Don't expect any of the Artemis II moon astronauts to fly again soon.

On Tuesday (Oct. 13), NASA announced that Artemis II mission specialist Christina Koch will become the agency’s acting deputy chief engineer, effective Nov. 1.

"With this appointment, Koch will transition to management astronaut status and will no longer be eligible for future spaceflight assignments," NASA officials wrote in a statement on Tuesday.

Her three Artemis II crewmates had already shared their next moves, none of which put another spaceflight in play in the near future.

Mission commander Reid Wiseman and pilot Victor Glover, both of NASA, became "emeritus" astronauts last month, a role that seems to include planning, advising and mentoring duties but no flights into the final frontier. Glover will also work full-time at his alma mater, the California Polytechnic State University (Cal Poly) in San Luis Obispo.

"I'm grateful they will continue sharing what they learned with our astronauts, flight controllers and engineers as we prepare for Artemis III in 2027 and the missions that follow," NASA Administrator Jared Isaacman said of Wiseman and Glover in a Sept. 9 statement.

The fourth Artemis II astronaut, mission specialist Jeremy Hansen of the Canadian Space Agency, announced a change of his own in July: He planned to become a reservist in the Royal Canadian Air Force, where he's also a colonel. That move became official last month as well.

Artemis II sent the four astronauts on a 10-day trip around the moon in an Orion capsule. It was the first crewed mission of NASA's Artemis program and the first human spaceflight beyond low Earth orbit (LEO) since Apollo 17 in 1972.

As Isaacman mentioned, the next mission in the program is Artemis III, a docking test in LEO scheduled to launch next year. The Artemis III crew, which was announced in June, consists of NASA astronauts Randy Bresnik (commander), Andre Douglas and Frank Rubio (mission specialists) and Luca Parmitano of the European Space Agency (pilot).

If all goes according to plan, Artemis IV will land astronauts near the moon's south pole in 2028. We don't yet know who will fly on that historic mission.

Koch will succeed current NASA Deputy Chief Engineer Katherine Van Hooser, who will retire on Oct. 21 after more than 35 years of work for the space agency.

"In her new role, Koch will help lead NASA's engineering community, supporting technical oversight, mission readiness, and engineering excellence across the agency's programs and projects," agency officials said in Tuesday's statement.

Koch is a natural choice for the job, given her education and experience. She holds bachelor's degrees in electrical engineering and physics and a master's in electrical engineering, and she began her NASA career as an electrical engineer at Goddard Space Flight Center in Maryland.

NASA selected Koch as an astronaut candidate in 2013. She has two spaceflights under her belt: Artemis II and a 328-day-flight to the International Space Station that launched in March 2019. That's the longest space mission ever conducted by a woman, and it featured the first three all-female spacewalks, which Koch conducted with fellow NASA astronaut Jessica Meir.

"Christina has seen NASA engineering from both sides of the equation: developing complex systems on the ground and trusting them with her life in space," Isaacman said in the Tuesday statement.

"After spending nearly a year living and working aboard the International Space Station and helping lead America back around the moon on Artemis II this year, she brings an extraordinary combination of technical expertise, operational experience, and judgment to this role," he added. "I am excited to see the impact she will have across NASA as we return Americans to the lunar surface, build the Moon Base, get underway on nuclear power in space, and develop the capabilities that will ultimately take us on to Mars."

NASA's DART mission made a cosmic mess four years ago — and now a new spacecraft is ready to scout out exactly what the first-of-its-kind collision accomplished.

The Double Asteroid Redirection Test (DART) spacecraft slammed into a small space rock called Dimorphos on Sept. 26, 2022, in humanity's first test of planetary defense. That's the field dedicated to protecting Earth from the possibility of a calamitous asteroid impact, and DART mimicked how humans could change the orbit of a threatening space rock, taking it off its collision course.

The mission definitely succeeded, shortening the little asteroid's orbit around a larger rock called Didymos by about 33 minutes. But in order to make the most of the experiment, scientists ensured a second spacecraft would follow DART at a more leisurely pace. That decision will pay off this month with the arrival of a European Space Agency (ESA) spacecraft dubbed Hera, which launched in October 2024, two years after DART's impact.

"Hera wants to be the detective, like Inspector Colombo, going back to the crash scene," said Patrick Michel, a planetary scientist at the French National Centre for Scientific Research (CNRS) and principal investigator of the Hera mission.

Scientists have been able to do limited monitoring of the Didymos system over the years with telescopes both on the ground and in space. That's how they calculated the basic change to the orbit, and they've built a basic sketch of what happened.

"We know that there was a lot of material kicked up," said Angela Stickle, a planetary scientist at Johns Hopkins University's Applied Physics Laboratory affiliated with both missions. "We know that we probably left a pretty significant mark on Dimorphos."

But the story isn't over and scientists are far from satisfied. No one knows how big a crater the impact left, or whether it completely rearranged all the asteroid's boulders. There are hints Dimorphos is now tumbling, and material may have moved between it and the larger Didymos.

Even the change to the orbit is complicated, said Cristina Thomas, a planetary astronomer at Northern Arizona University affiliated with both missions: The time Dimorphos took to circle Didymos was still changing some six months after impact, for reasons that aren't clear. "This thing that we thought was going to be very cut and dry turned out to be really interesting and complicated," Thomas said.

That's where Hera comes in, with its first arrival maneuver scheduled for Oct. 15. During three careful braking maneuvers, the spacecraft will slow down and approach the space rocks. Assuming everything goes smoothly, by early November, the spacecraft will come within 20 miles (30 kilometers) of the two rocks and begin its early science observations, then move even closer in early December.

Mission personnel can't wait for their first glimpses of Dimorphos — the first time scientists will visit someplace they've seen before without knowing what they'll find. "For us, it's like a new world," Michel said. "The new image won't have anything to do with the previous one, so that's really exciting."

In addition to mapping the two asteroids and seeing what kind of crater the impact left, scientists will also have their eyes peeled for any pieces of the DART spacecraft, although they don't expect to find anything. "We were coming in really fast, so typically, the whole spacecraft you would expect to just kind of shatter or melt," Stickle said. The only sliver of possibility is that part of the two long solar panels stretching off the spacecraft may have snapped off and survived. (The appendages may also have turned the crater shape into an oval.)

In January, once Hera has settled in, it will release two tiny companions that have piggybacked out to Dimorphos. One, called Milani, will identify the composition of materials on and around Dimorphos. The other, Juventas, will use radar to peer inside Dimorphos — the first time scientists have ever been able to study the interior of a space rock directly. Juventas will end its mission by landing on the small asteroid, and Milani may attempt a landing as well.

The trio of spacecraft will operate in tandem throughout early 2027, and the main spacecraft will operate at least through September 2027. All told, they will give scientists an unprecedented look at the pair of asteroids — the first binary asteroid a spacecraft has ever studied in detail. And the Didymos–Dimorphos duo is a good one to visit first. "It's very ordinary, and I mean that in the best possible way," Thomas said.

Ordinary except, of course, for that time humans punched it, opening the door for the Hera mission to explore the previously unremarkable rocks. And finally, that moment is just around the corner.

"Nothing really worries me," Michel said of the spacecraft's arrival. "It's really just excitement now."

In a milestone achievement, NASA's Perseverance Mars rover has broken the record for most miles driven on a world beyond Earth.

On Oct. 11, Perseverance hit 28.10 miles (45.22 kilometers) traveled on Mars, breaking the record previously held by NASA's Opportunity rover which went 28.06 miles (45.16 km). It took Oppy 14 years to cover all that ground; Perseverance, by contrast, has been on Mars for just 5.5 years.

The new record is far from the end of Perseverance's journey, however; the mission team thinks the rover could eventually more than double the distance it's already traveled.

"Our original design was only planned to last for [about] 20 kilometers of driving," Mark Maimone, a rover driver at NASA's Jet Propulsion Laboratory (JPL) in Southern California, told Space.com.

"We've more than doubled that already … and we're looking really good to go for up to 100 kilometers total," added Maimone, who works as a designated principal in autonomous planetary rover navigation on Perseverance and helped to develop the autonomous driving systems on NASA's previous Mars rovers.

"So we could double what we've done so far," he said. "And we have great expectations that [Perseverance] can continue its mission of exploring and collecting really useful and beneficial samples that will tell us so much more about the history of Mars."

Indeed, Perseverance remains in great shape, mission team members stressed.

"We are very fortunate that all of Perseverance's original capabilities are more or less intact, especially for the science instruments," JPL's Vivian Sun, the mission's deputy project scientist, told Space.com.

Perseverance landed on the floor of Mars' 28-mile-wide (46 km) Jezero Crater in February 2021. It was far from the first robot to traverse the planet's surface; the Perseverance team built on years of experience with the Sojourner, Spirit, Opportunity and Curiosity rovers.

Through the triumphs and missteps of these previous craft, NASA learned how to better explore another planet with a rover operated from millions of miles away. Perseverance saw massive improvements made to everything from its specialty wheels to its autonomous driving system and onboard tools and instruments.

This "could not have been done without the previous missions that we've sent to Mars," Sun said.

"Five years later [after landing], we're definitely a very well oiled machine," she added. "There's a lot of technical advancements on Perseverance that are the result of many people, many engineers, working on this new technology year after year for decades now."

And, according to both Sun and Maimone, this teamwork is the real secret behind Perseverance's endurance and success.

"The magic sauce for our operations team is how cohesively we work together," Sun said. The engineers, rover drivers and science team all work together and keep each other's work in mind as they make decisions on everything from driving speed to science targets, she added.

"I'm just super appreciative of all the people that have and still work on the mission. They're really what makes the mission special," Sun said.

What's next for Perseverance

As the team mentioned, Perseverance is nowhere near done on Mars. The rover could keep driving for many more miles on the Red Planet, and the scientists and engineers at NASA have big plans and high hopes for its future.

"We are currently planning to continue down south on the crater rim," Sun said. "There's a whole diversity of different rocks along this crater rim going south that we want to investigate and figure out how it indicates conditions from early Mars."

Jezero is a giant crater created by an impact from an asteroid or comet billions of years ago. Perseverance's work has shown that Jezero hosted a lake for long stretches billions of years ago. Scientists are therefore eager to continue exploring the site, searching for clues about what the planet looked like in the ancient past, and if it could have possibly hosted life.

"There are huge chunks of pre-Jezero crust that were embedded in the stratigraphy or got thrown up by the impact, and they're now incorporated onto the crater rim," Sun said. "These are our chance to probe like really old rocks that don't really exist in any other form on the surface anymore."

As part of Perseverance's next steps south on the crater rim, the team is heading toward an area called "Rainbow Falls."

Sun said that the Rainbow Falls area is thought to have kaolinite, a clay mineral that forms when water interacts with rock. By studying these types of minerals, mission scientists might be able to get a better idea of the conditions on Mars all of those billions of years ago, when water filled Jezero Crater.

"Whenever we are looking at clay minerals, I think the question of habitability and the search for potential biosignatures is always on the table," Sun said. "So that is very much the case when we get to Rainbow Falls, or even when we see kaolinite."

Northrop Grumman's robotic Cygnus XL spacecraft departed the International Space Station today (Oct. 9) after a six-month stay.

Northrop Grumman's uncrewed Cygnus XL freighter was released by the station's huge Canadarm2 robotic arm today at 12:44 p.m. EDT (1644 GMT), while the duo flew 260 miles (418 kilometers) above the Pacific Ocean.

The departing vehicle is the second of Northrop Grumman's "Cygnus XL" line of freighters but the 24th Cygnus of any type to fly cargo to the orbiting lab. The company named it the S.S. Steven R. Nagel, after a NASA astronaut who flew four space shuttle missions in the 1980s and 1990s.

The S.S. Steven R. Nagel launched atop a SpaceX Falcon 9 rocket on April 11, carrying 11,000 pounds (4,990 kilograms) of science gear and supplies to the International Space Station (ISS). It's carrying some stuff down as well — thousands of pounds of trash, which will burn up along with the Cygnus when it reenters Earth's atmosphere on Sunday (Oct. 11).

That's the usual fate for three of the four robotic ISS resupply vehicles in operation today — Cygnus XL, Russia's Progress and Japan's HTV-X. Only SpaceX's Dragon cargo capsule is reusable; it wraps up its orbital flights with parachute-aided ocean splashdowns.

Cygnus XL is different than Dragon in another way as well: The Northrop Grumman vehicle does not dock to the ISS on its own. Rather, it's grappled by Canadarm2, which berths it to the station and moves it around in other ways as necessary.

During today's operation, which was commanded from the ground, Canadarm2 detached the S.S. Steven R. Nagel from the Earth-facing port of the ISS' Unity module and then maneuvered it into position for release at 12:45 p.m. NASA astronaut Luke Delaney monitored these activities from the ISS.

"We're just really excited to have had the S.S. Stephen R. Nagel on board, and all the science and research, critical hardware," Delaney said shortly after the Cygnus was released.

"Appreciate all the teams that came together to make this complex operation a success, from assembly, launching, docking and now the undock," he added. "Thanks for continuing to push the boundaries of human knowledge and experiments on board, to include the research during this deorbit phase. These true are the building blocks of the future of space exploration."

And about that deorbit science: The S.S. Stephen R. Nagel is carrying heat shield prototypes that will get a test during the freighter's fiery reentry.

Editor's note: This story was updated at 1 p.m. ET on Oct. 9 with news of the Cygnus XL's departure from the ISS.

We have our first look at the science from Artemis II, and it's as amazing as we might have hoped.

This past April, four astronauts strapped in for a flyby around the moon and back to Earth. The first mission to the moon since the Apollo program ended in 1972, this success marked an incredible historic milestone. The Artemis II crew also conducted groundbreaking science, observing parts of the moon no human had ever laid eyes on before. And now, we have our first look at some of the science from the mission.

"It's the science community's job now to take these data and go do magical things with it," David Hollibaugh Baker, a member of the Artemis II Lunar Science Team, said during a Wednesday (10/7) press conference that announced the mission's initial science results.

This is just the first batch of data from the mission, but it includes a whopping 996 new images, 814 GB of observations and 521 minutes of audio from the crew that has never been heard before. Everything from that astronauts' handwritten notes and drawings to photographs and verbal observations have revealed exciting new information — about impact flashes on the moon, for example, as well as the terminator line between the lunar "day" and "night" sides and a whole range of lunar colors and observations from beyond the mysterious far side.

Let's take a quick look at some of the highlights.

Impact flashes

"Dude, no way!" Artemis II commander Reid Wiseman of NASA exclaimed in newly released mission audio.

"It's just like a 'bloop!'" mission specialist Jeremy Hansen of the Canadian Space Agency added as the flashes appeared on the lunar surface. .

As Artemis II's Orion capsule flew by the moon, the four astronauts onboard — Wiseman, Hansen and NASA astronauts Victor Glover (mission pilot) and Christina Koch (mission specialist)— started seeing flashes of light on the lunar surface. These were impact flashes caused by small rocks hitting the lunar surface and vaporizing in the impact.

"We have seen three impact flashes so far," Wiseman said to Mission Control at NASA's Johnson Space Center in Houston. "It was not sun glint off a particulate from the thrusters or the purge tanks. It was definitely impact flashes on the moon."

"Amazing news," Mission Control responded. "I literally just looked over at the SER [Science Evaluation Room], and they were jumping up and down, literally."

In total, the crew saw five impact flashes on the moon's surface, which the mission's science team was able to confirm didn't come from other sources.

While the Artemis II crew was equipped with cameras, they were also trained to make observations with the unaided eye. And impact flashes happen too quickly to photograph them, so — as you can see above — the crew used a tablet to make annotations and describe their observations.

"We wanted them to look visually, so there are not camera images of that, but we have their annotations of when they saw them," Jennifer Heldmen, science theme lead for the Artemis II mission, said during the briefing.

A rainbow moon

In addition to seeing impact flashes across the lunar surface, the Artemis II crew observed a wide range of colors on the moon.

Looking up in the night sky, it might seem that the moon is just shades of gray. But as the astronauts saw during their flyby, the moon is gray, black, brown, tan, white, green and even blue. This muted rainbow of colors was not only visually striking, as the astronauts' photos show, but it can also help scientists determine what types of rocks and minerals might be found in different regions across the moon's surface.

"The crew reported greens and yellowish hues on top of Aristarchus Plateau, signaling they were seeing remnants of different styles and epochs of volcanic activity, and the crew contrasted those colors to nearby browns and grays of adjacent volcanic plains," Ariel Deutsch, a member of the Artemis II Lunar Science Team, said during the briefing, givingone example of these colorful observations.

"To me, it's primarily like a brownish-green glass, and then if I went up into the mares [dark volcanic deposits] to the north of Aristarchus, I would give that a very muted brown," Wiseman said in mission recordings shared in this release.

"It's like a jaundiced cheek of the moon," Koch remarked in mission audio, describing yellowish colors on the moon.

And while the crew took some amazing photographs of the moon, in this data release we can also see their handwritten notes annotating the colors they saw on the moon.

The far side of the moon

As the moon is tidally locked to Earth, it has one "day side" that always faces us and one far or "night side" that is always facing away. When the Artemis II astronauts flew by the moon, they flew around the entire object, even around the far side. During their flyby, they were able to see a part of the far sidethat has never been observed up close like this before.

"The Artemis II crew were the first people to see this section of the moon illuminated in all of human history," Alex Stoken, a member of the Crew Lunar Observations team, said during the briefing.

When they approached the moon's far side, the crew also came upon the terminator line, or the boundary between the day and night sides of the moon.

At the terminator, the team was able to view the incredible contrasting shadows and textures of the lunar surface, revealing sharp details about the moon's topography.

"The terminator is the most striking thing that I’ve seen so far," Glover said as the crew flew by.

As they rounded the moon's far side, the moon was backlit by the sun, essentially eclipsing it. This allowed for incredibly unique and sharp views of the moon.

"You’ve got to be kidding me," Koch said in the capsule. "You can actually see mountains."

These are just a few highlights from this incredibly thorough and detailed data release. As we dig deeper into this initial science, you can take a dive through the data yourself here and here.

World Space Week 2026 is off to a great start, and everyone's favorite daily pop culture animation has joined the celebration.

Today's Google Doodle (Oct. 6) features the tech company's logo over a sparkling view of the Rosebud Nebula. The image was captured by NASA's James Webb Space Telescope (JWST), with stars that shimmer periodically on the search engine's home page.

This year's World Space Week runs from Oct. 4 through Oct. 10. The theme, "Rocket Revolution," highlights the leaps in accomplishments humanity has achieved over the past decade and more of spaceflight, with the goal of uniting industry leaders, agencies, educational institutions, students and enthusiasts for space-related activities and celebrations around the globe.

"This World Space Week 2026 Doodle celebrates the technology behind awe-inspiring astrophotography," it says on the Oct. 6 Google Doodle page, which shares a brief description of the Rosebud Nebula:

"Located 3,300 light-years away, this reflection nebula is home to over 130 young stars. Its clouds of gas and dust form a physical shape resembling an unopened, blooming rosebud, glowing rosy-pink from dust heated by these stars."

World Space Week was officially established by the United Nations in 1999. It marks the dual observance of launch of Earth's first artificial satellite, Sputnik 1, on Oct. 4, 1957, and the 1967 signing of the Outer Space Treaty on Oct. 10, which solidified the basic principles for peaceful exploration of the cosmos.

The four astronauts of SpaceX’s Crew-12 mission returned to Earth this morning (Oct. 8) after nearly eight months in space.

Crew-12's Crew Dragon capsule, named "Freedom," undocked from the International Space Station (ISS) on Wednesday morning (Oct. 7), beginning a roughly 27-hour trip back to its home planet.

Everything went well during the journey: Freedom splashed down as planned in the Pacific Ocean off the coast of Los Angeles today at 11:34 a.m. EDT (1534 GMT). Not long after that, the four astronauts were safely extracted from the capsule aboard a recovery ship. They'll be taken to terra firma for standard medical examinations and to begin the 45-day-long postflight conditioning process, which will help their bodies readjust to life with gravity.

"The crew is doing well. They were all smiles exiting the capsule," Bill Spetch, deputy manager of commercial, NASA’s Low Earth Orbit Program, said during a post-splashdown press conference today. "It's great to have them back after 237 days in space, 235 of those on the space station."

The Crew-12 astronauts are Jessica Meir and Jack Hathaway of NASA, the European Space Agency's (ESA) Sophie Adenot, and Andrey Fedyaev of the Russian space agency Roscosmos. Meir and Fedyaev had each been to space once before, while Crew-12 was the first mission for Hathaway and Adenot.

The quartet launched to the ISS atop a SpaceX Falcon 9 rocket on Feb. 13. Their arrival brought the station up to its normal complement of seven crewmembers. It had been operating with a skeleton crew of three since Jan. 15, when SpaceX's Crew-11 mission headed home a month early to deal with a medical issue experienced by one of its astronauts, NASA's Mike Fincke.

That was the first medical evacuation in the long history of the ISS. But it was not an emergency situation, NASA officials stressed at the time, and Fincke is doing fine now here on terra firma. (He retired in August with a total of 549 days in space, the fourth-most ever for a NASA astronaut.)

Crew-12, in turn, was relieved by the four-person Crew-13, which arrived at the ISS last Thursday (Oct. 1). Crew-13 made it to the station less than eight hours after launch — the quickest-ever ISS trip for an American spacecraft. (The world record is just over three hours, by a Russian Soyuz crewed vehicle.)

Crew-13 was originally supposed to launch on Sept. 12. However, an issue with the propulsion system on its Crew Dragon capsule, named "Grace," pushed things back, giving Crew-12 a few extra weeks in orbit.

The Crew-12 astronauts were very busy during their nearly 10 months off Earth, performing a variety of maintenance work and dozens of scientific experiments.

Then there were the spacewalks. Meir performed four of them, bringing her lifetime total to seven. And on Aug. 18, Adenot stepped outside the ISS, becoming the first French woman ever to walk in space. She did two more over the next two weeks, including one with Meir, which was just the sixth all-female extravehicular activity in the station's history.

Adenot also set a record on Crew-12, spending more time in space continuously (237 days) than any other ESA astronaut ever had. Luca Parmitano set the previous record of 201 days back in 2019-2020.

The Crew-12 astronauts felt a mix of emotions about their homecoming, as big transitions are always bittersweet. Indeed, Meir gave us a sense of this a few weeks back.

"What I'm looking forward to most is seeing my three-and-a-half-year-old daughter,” Meir said during a Sept. 16 call with reporters from the station.

"I'm so looking forward to seeing nature again," she added, "feeling the breeze on my face, the wind rustling through the leaves, experiencing all those things that we don't have up here. But I will very, very much miss being weightless all the time and the incredible views that we have."

Splashdown didn't wrap up all Crew-12 activities today. NASA and SpaceX will talk about the mission this afternoon, during a press conference scheduled to start at 1:15 p.m. EDT (1715 GMT). The briefing will also discuss the planned Oct. 13 launch of SpaceX's robotic CRS-35 cargo mission to the ISS. Participants are:

• Bill Spetch, deputy manager of Commercial, NASA's Low Earth Orbit Program
• Dr. Liz Warren, deputy chief scientist, NASA's Low Earth Orbit Program
• Lee Echerd, senior mission manager, Customer Operations and Integration, SpaceX
• Andreas Mogensen, leader, Human Exploration Group, (ESA)

Editor's note: This story was updated at 8:30 a.m. ET on Oct. 7 with news of successful undocking. It was updated again at 6 p.m. ET that day to correct its headline, which previously said the Crew-12 astronauts have spent nearly 10 months in space. It was updated again at noon ET on Oct. 8 with news of successful splashdown.

SpaceX's latest astronaut launch just set a new space record.

The company's Crew-13 mission for NASA arrived at the International Space Station (ISS) today (Oct. 1) at 7:05 p.m. EDT (2305 GMT), 7 hours and 55 minutes after it launched from Florida's Space Coast.

That's the fastest any American spacecraft has ever reached the orbiting lab, NASA officials said.

The previous record was 12 hours and 33 minutes, set in November 2024 by SpaceX's Dragon cargo capsule during the robotic CRS-31 resupply flight. The fastest that astronauts had made the trip in a U.S. vehicle was 14 hours and 43 minutes, which was achieved by the Crew-11 mission in August 2025.

"We got lucky this time," Julianna Scheiman, director of NASA science and Dragon programs at SpaceX, said during Crew-13's post-launch press conference today.

"The space station was in an opportune spot in space, and the orbital mechanics, the physics of it all, worked out for it to be the shortest launch-to-docking time we've had to date," she said, adding that "this is close to the fastest it could be."

Crew-13 didn't set the overall speed record to the ISS, however — not even close. In May 2020, a Russian Soyuz spacecraft carrying three astronauts reached the orbiting lab just 3 hours and 3 minutes after lifting off from Baikonur Cosmodrome in Kazakhstan. The Soyuz caught up to the ISS after just two orbits of Earth.

The Soyuz isn't faster or more powerful than a cargo or crew-carrying Dragon capsule. Rather, the difference in chase-down times comes down primarily to choices made by mission controllers; Russia tends to target more aggressive "fast-track" trajectories.

Crew-13 delivered four astronauts to the orbiting lab: NASA's Jessica Watkins and Luke Delaney, Joshua Kutryk of the Canadian Space Agency and Sergey Teteryatnikov of the Russian space agency Roscosmos. The quartet will live and work in space for the next six months.

They'll relieve the four astronauts of SpaceX's Crew-12 mission, which launched in mid-February. Those spaceflyers — NASA astronauts Jessica Meir and Jack Hathaway, the European Space Agency's Sophie Adenot and cosmonaut Andrey Fedyaev — could return to Earth in their Crew Dragon capsule as soon as Monday (Oct. 5), according to NASA officials.

In case you are feeling the empty hole of moon missions, void since the return of the Artemis II astronauts from their trip around the lunar far side six months ago, NASA has you covered.

The agency's Space Launch System (SLS) rocket launched Artemis II on April 1, carrying a crew of four on the first mission around the moon since the Apollo program ended in 1972. SLS lifted off from Launch Complex-39B at NASA's Kennedy Space Center (KSC) in Florida, and, to the awe of hundreds of thousands, climbed a bright blue early evening sky on a trail of smoke left by the vehicle's solid rocket boosters up into space.

More than 300,000 people traveled to the Space Coast to watch the launch from dozens of locations around KSC and surrounding cities. But the best views wouldn't be seen until well after the rocket cleared the pad, when NASA technicians recovered the slew of engineering footage captured by dozens of specialized cameras distributed everywhere from the base of the launch pad to drones positioned in the air to track every detail of the launch. Now, NASA has released that footage to the public.

The newly-released videos include a wide spectrum (literally) of views and angles that follow SLS from just before engine ignition through solid rocket booster separation as the rocket leaves Earth's atmosphere. NASA teams used scientifically calibrated in-flight imaging (SCIFLI) to compile footage ranging from the visible light spectrum, to short-wave infrared (SWIR), near-infrared (NIR), mid-wave infrared (MWIR) and infrared — to give you a few helpful acronyms for context as you pursue these videos on NASA's Artemis II album. These different wavelengths of light captured views imperceivable to the eye and typical camera sensors, and allowed NASA technicians to filter out things like the extreme brightness of the flames from the rocket’s engines.

Artemis II was the first crewed mission of NASA's Artemis program, which aims to establish a permanent base on the surface of the moon in the 2030s. It was also the first flight of NASA's Orion spacecraft with astronauts aboard. Essentially a shakedown cruise for Orion's life support systems, the mission flew NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, as well as Canadian astronaut Jeremy Hansen on a 10-day flight around the moon and back to Earth.

The next mission in NASA's lunar line up, Artemis III, will last longer, but won't fly as far. Artemis III is scheduled to launch in mid-2027 with NASA astronauts Randy Bresnik, Frank Rubio and Andrew Douglas, as well as European Space Agency (ESA) astronaut Luca Parmitano of Italy. They will launch aboard Orion to Earth orbit, where their spacecraft will rendezvous with the two commercial lunar landers NASA has contracted for the Artemis program, SpaceX's Starship and Blue Origin's Blue Moon.

Artemis III is expected to last about two weeks as Orion will rendezvous and dock with each lander separately to test the spacecrafts' interoperability. That mission will serve as a precursor to the program's first actual lunar landing with astronauts on Artemis IV, which NASA is targeting to lift off in 2028.

City lights streak by as stars twinkle in the distance in this image captured from aboard the International Space Station (ISS).

What is it?

In a photo recently captured by NASA astronaut Anil Menon from the ISS, bars of city light can be seen streaking beneath the station — 262 miles (422 kilometers) beneath, to be exact. It's just one fleeting moment, but it showcases both the unnatural beauty of the city lights as well as the natural beauty of our planet and the stars in the distance.

The city lights beam from Central Asia. They're streaking because the ISS travels at about 17,500 mph (28,000 kph), and this image was captured as a long exposure. Auroras blaze on the lefthand side of the photo, and star trails sparkle across the blackness of space in the distance.

Why is it incredible?

All in one image, we can see streaking city lights, an extension of the ISS and its hardware, colorful auroras glowing green, red and orange, and star trails speckling the cosmos.

In just this one long-exposure image, Anil has captured the beauty of Earth, its human-populated cities, the universe we inhabit and the incredible technology we have managed to create and sustain in orbit.

It also remains incredible that, while so much amazing science and technical progress happens aboard the space station, it is also a place where art like this photograph can be made. Even in space, hundreds of miles above Earth, hurtling at thousands of miles per hour, astronauts working hard to make progress for humanity are able to find brief moments of transcendent beauty.

Russia's robotic Progress 96 cargo spacecraft met up with the space station today (Sept. 19).

Progress 96 launched atop a Soyuz rocket from Baikonur Cosmodrome in Kazakhstan on Wednesday (Sept. 16), kicking off a three-day orbital chase of the International Space Station (ISS).

That chase came to an end today at 9:44 a.m. EDT (1344 GMT), when the freighter docked with the space-facing port of the ISS' Poisk module. The two spacecraft were flying 260 miles (418 kilometers) above the Black Sea at the time, according to NASA's docking webcast.

Progress 96 carried about 3 tons of food, fuel and other supplies for the occupants of the ISS.

There are currently seven of those folks: Jack Hathaway, Jessica Meir and Anil Menon of NASA, the European Space Agency's Sophie Adenot, and Pyotr Dubrov, Andrey Fedyaev and Anna Kikina of Russia's space agency, Roscosmos.

Progress 96 will stay attached to the ISS for about five months. It will then be loaded up with trash and sent to burn up in Earth's atmosphere.

This is the ultimate fate of most ISS resupply spacecraft — every Progress, HTV-X vehicle (which is built by the Japan Aerospace Exploration Agency) and Cygnus (provided by Northrop Grumman). The only reusable freighter in the current fleet is SpaceX's Dragon capsule.

Europe's prototype spacesuit aboard the International Space Station (ISS) still needs some work after European Space Agency astronaut Sophie Adenot performed its first fit and dexterity checks on orbit.

EuroSuit launched aboard the SpaceX CRS-34 Cargo Dragon mission, which lifted off May 15 and docked to the ISS about two days later with nearly 6,500 pounds (2,950 kilograms) of supplies and equipment. Adenot arrived on the ISS three months earlier, in February, as a member of the SpaceX Crew-12 mission. Her time with the suit gave European engineers their first astronaut feedback on the intravehicular activity (IVA) prototype in orbit, and she did not give a five-star review.

"I think there are still a lot of points that will be improved in the future," Adenot told Space.com on Sept. 16, during a call with reporters previewing the Crew-12 mission's impending return to Earth. "We are looking forward to the future steps."

EuroSuit was developed by the French Space Agency (CNES), the Institute of Space Medicine and Physiology (MEDES), spaceflight systems company Spartan Space, and sports clothing brand Decathlon. As the "I" in IVA suggests, EuroSuit is not designed for spacewalks. It's meant for use inside a spacecraft during the most critical phases of flight, specifically launch and landing, similar to the black-and-white spacesuits worn by astronauts who launch aboard SpaceX's Crew Dragon.

One of the suit's biggest innovations is supposed to be its ease of use. EuroSuit is designed for astronauts to put on, without help from another crewmember, in less than two minutes, and take off in the same amount of time. This would be a big advantage in emergency situations when astronauts may need to don their suits quickly — for example, to deal with a spacecraft pressure leak or to evacuate the space station.

Adenot's on-orbit tests focused on the ergonomics of the suit, rather than full life-support performance. She was tasked with donning and doffing the suit and assessing its dexterity by handling small objects and manipulating a tablet's touchscreen.

EuroSuit fits into a broader European effort to build more independent capabilities in space. CNES says the project reflects Europe's ambition to be more autonomous in human spaceflight, with the French space agency focusing specifically on intravehicular suits.

"By relying on the exceptional expertise of our partners, we are prepared to deliver this type of suit when the time comes," Sébastien Barde, CNES deputy director for exploration and human spaceflight, said in a statement last year.

The project is coordinated by CNES, which brought together the aerospace, medicine and activewear expertise that went into EuroSuit's development. Spartan Space, the suit's primary contractor, created the overall design, with MEDES contributing biomonitoring systems for tracking astronaut vital signs and other data. Decathlon brought ergonomic insight into textiles meant for extreme environments.

Feedback from Adenot's ISS tests will help guide EuroSuit technicians toward a more informed architecture, which will include key systems like pressurization, atmospheric control, and communications that will be needed for the final design.

"This EuroSuit is at the very first step of its development," Adenot said. "Everything in the design of space systems goes incremental. I would say right now we are at the very beginning of its journey."

Leaving the International Space Station will be bittersweet for its outgoing crew, who’ve been living aboard the orbital lab since February performing maintenance and upgrades and carrying out dozens of microgravity research experiments.

The astronauts of SpaceX’s Crew-12 mission launched to the ISS on Feb. 13 and are now gearing up for their return to Earth. When exactly that might take place, however, is still up in the air, as their replacements don't yet have a launch date. NASA and SpaceX had targeted Sept. 12 for the liftoff of Crew-13, but have twice delayed that mission to allow additional time for preflight tests and data analysis. Now, NASA is targeting a Crew-13 launch no sooner than early October, according to a Sept. 16 statement from the space agency.

As is standard practice with ISS crew rotations, the astronauts of Crew-12 will remain aboard the station and continue a typical day-to-day schedule through a brief overlap period between crews once their replacements are safely aboard. In the meantime, the members of Crew-12 — NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency astronaut Sophie Adenot and Roscosmos cosmonaut Andrey Fedyaev — are reflecting on their time in space and also looking forward to the comforts of Earth upon their return.

The quartet gathered in the station’s Kibo laboratory module for a call with reporters yesterday (Sept. 16) to discuss the past several months aboard the ISS and their upcoming trip home. It was the first time “in quite a while,” Meir said, that just the four Crew-12 astronauts found themselves together. They currently share the station with the three astronauts of Russia’s Soyuz MS-29 mission — NASA's Anil Menon and cosmonauts Pyotr Dubrov and Anna Kikina.

Their coming together “really started evoking those memories of our trip up here and our ride on the [SpaceX] Dragon, and of course started to get us anticipating that ride home that hopefully we're going to have pretty soon around the corner,” Meir said on the call.

All four reflected on some of their most profound moments during their spaceflight and shared some of what they’re looking forward to once they’re back on Earth. “My biggest eureka moment happened just recently, on the final spacewalk that we did,” Meir said, referring to her Sept. 1 extravehicular activity (EVA). She performed a total of four EVAs during this current stint aboard the ISS, bringing her career total spacewalk tally to seven.

“It was the first time that I ever got to ride the Canadarm on a spacewalk,” Meir said, describing the EVA as a “full circle” moment. She helped fix the Canadarm during a previous spacewalk on this mission, “and then to ride it with these guys driving me around was the most incredible feeling,” she said.

Fedyaev recalled another notable spacewalk event. During the May 27 Roscosmos EVA that featured cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, Fedyaev controlled the station’s European Robotic Arm (ERA) with both his comrades attached.

“The most [memorable] moment in my flight was the work with the ERA manipulator,” Fadyaev said. “We moved … two cosmonauts in one moment on the ERA from SM module to the MLM module,” he added, referring to Russia’s Zvezda Service Module and Nauka Multipurpose Laboratory Module. It was the first-ever time that two cosmonauts were transported simultaneously between modules using the ERA, and the experience stood out for Fadyaev, who skillfully handled the robotic arm’s controls.

Adenot pointed to the second of her two spacewalks as a point of pride during what is her first mission to space. She and Menon spent the majority of their Aug. 18 EVA removing a failed Space-to-Ground Antenna (SGANT) on the station’s Z1 truss, but stuck bolts and electrical connectors ate up so much time that they had to defer installing the spare until Aug. 25. Adenot recalled her relief when engineering teams on the ground confirmed the new SGANT’s functionality. “After two EVAs trying to fix it with Anil, it was a great thing to hear,” she said.

The Crew-12 astronauts also discussed some of the science they’ve helped carry out during their time on orbit. One of Hathaway’s proudest moments came when he heard the celebrations from teams in mission control over ISS communications channels after the crew completed upgrades to the station’s Cold Atom Lab, which facilitates quantum mechanics experiments.

“We spent, it must have been two or three hours trying to figure out how to get this part to fit into the slide it was supposed to fit in,” Hathaway said. “Hearing the cheers … over the space-to-ground loops when we finally got it properly installed and it was ready to do science was a pretty fun moment for me.”

Some of Meir’s favorite experiments took place in the Life Sciences Glovebox, including investigations involving neocartilage and stem cells. “Previous experiments have shown that the stem cells actually divide for longer, more continuously, in microgravity than they do on Earth,” Meir said. “So potentially that's something very novel that was discovered. And potentially, if it becomes cost-effective, we could produce stem cells up here to be used for targeted therapies back on Earth.”

As for what they’re looking forward to once they return to Earth, the answer is pretty much everything. “One of the things about living in space is, it's an expeditionary lifestyle,” Hathaway said. “We don't have a lot of selection of food. We don't have running water … So going home and being able to take a nice long hot shower will be very relaxing and very nice. And of course, I'm looking forward to seeing my family. But a hot shower is near the top of my list.”

Adenot, too, has her mind in the water. “I love water sports,” she said. “We don't have a lot of variety of sports [aboard the ISS], and obviously we don't have water sports. So I'm looking forward to these.”

“What I'm looking forward to most is seeing my three-and-a-half-year-old daughter,” Meir said, and added a few more things to her list. “I'm so looking forward to seeing nature again,” she said, “feeling the breeze on my face, the wind rustling through the leaves, experiencing all those things that we don't have up here. But I will very, very much miss being weightless all the time and the incredible views that we have.”

Like most test pilots, Jack Hathaway was always looking for a faster and more capable winged vehicle to fly. Even as a kid, he dreamed of being at the controls of the "coolest plane out there."

Unfortunately for him, he was a few years too young.

NASA's first space shuttle orbiter, OV-101 or "Enterprise," made its debut 50 years ago today (Sept. 17). Though only a prototype used for atmospheric and ground tests, Enterprise proved that a spacecraft could launch like a rocket and land as a glider, enabling the world's first reusable orbital platform.

Enterprise became a museum piece in 1985. Twenty-six years later, the three-surviving space-worthy orbiters followed, permanently landing in institutions on both U.S. coasts. Hathaway did not become an astronaut until a decade after that.

"It was definitely one of my goals to be able to fly something like it someday, and didn't quite make it. Maybe [had I] been a couple years older I would have, but I look back at it and it was pretty awesome," said Hathaway on Wednesday (Sep. 16), taking part in a press conference from on board the International Space Station. "It built this space station, which [people] have inhabited now for over 25 years, which is pretty awesome.

"We're thankful for the people that flew the space shuttle who came before us," he said.

'A great day'

"Would you now roll out orbiter 101, now christened the 'Enterprise,'" directed Jim Fletcher, then the NASA administrator, on Sept. 17, 1976, as he stood before an audience outside the vehicle's manufacturing plant in Palmdale, California.

As the crowd caught its first glimpses of the now familiar black-and-white winged spacecraft, a marching band performed the theme to "Star Trek." Most of the TV show's primary cast were there as NASA's invited guests. OV-101 was originally going to be named the "Constitution" before a grassroots letter writing campaign convinced the government to name its first space shuttle after the show's fictional starship.

"We are on the verge of a new era," said Barry Goldwater, the then-ranking minority member of the U.S. Senate's Committee on Aeronautics and Space Sciences. "As we witness today the rollout of the space shuttle, we are on the verge of a new era, not only in spaceflight, but in the lives of men and women and children all across this Earth."

"I submit that the space shuttle will present us with a remarkable opportunity to exploit the new frontier of space for the benefit of all mankind and to continue to expand our knowledge of the space environment in which we live," he said.

"What a great day that was in 1976!" recalled Star Trek's Spock, actor Leonard Nimoy, as the Enterprise arrived in New York for its display at the Intrepid Museum in 2012. "It was a great day for America, a great day for us to be connected to that history."

An inspiration

NASA astronaut Jessica Meir was born 10 months after Enterprise's reveal. Like Hathaway, her Expedition 74 and SpaceX Crew-12 crewmate, she grew up watching the space shuttle fly.

"I do think that the space shuttle program had a huge part in inspiring me," she said from on board the ISS in response to a question from collectSPACE. "When people ask me what made me want to be an astronaut, you know, there wasn't one moment that I describe, but I very vividly recall in the classrooms [watching] space shuttle launches."

In February 1977, five months before Meir was born, Enterprise made its first flight mounted to the top of NASA's Shuttle Carrier Aircraft. It flew a total of 16 times, of which five saw it separate from the 747 and land on its own on the dry lakebed at Edwards Air Force Base in California. Two pairs of two astronauts each took turns flying the tests: Fred Haise and Gordon Fullerton as one crew and Joe Engle and Richard Truly as the other.

Before turning Enterprise over to the Smithsonian, one of the last uses NASA had for the orbiter was to inspire and engage the public. The orbiter was the only one in history to be carried atop a Boeing 747 on a transatlantic tour of European countries and be displayed at the Paris Air Show in France in 1983. It was also exhibited at the 1984 Louisiana World Exposition in New Orleans.

"Seeing them when we were growing up as kids in the classroom, seeing it on the evening news — I think that was one of the things that really inspired me and got me interested in spaceflight and exploration in general," Meir said.

Fifty years ago, NASA rolled out its first space shuttle while a host of iconic Star Trek actors watched on to celebrate the historic step forward in human spaceflight.

What is it?

On September 17, 1976, NASA rolled out the space shuttle Enterprise, the first-ever space shuttle (which happens to bear the same name as the USS Enterprise from Star Trek).

This grand reveal took place at the Rockwell manufacturing facility in Palmdale, California — and there was no shortage of fanfare. As the shuttle rolled out of its hangar, the Air Force Band of the Golden West played music from Star Trek as a crowd of 600 guests looked on and listened.

Among the guests were Star Trek icons including series creator Gene Roddenberry; Leonard Nimoy, who played Mr. Spock; Nichelle Nichols (Lt. Uhura); George Takei (Mr. Sulu); James Doohan (Chief Engineer Montgomery Scotty Scott); DeForest Kelley (Dr. Bones McCoy); and Walter Koenig (Ensign Pavel Chekov). The crew took a moment to pose in front of the shuttle with NASA Administrator James D. Fletcher.

Why is it incredible?

The start of the space shuttle program was a "historic step in the nation's space program," Fletcher said at the time.

And today, 50 years in the future, it is clear in looking back that this truly was a historic step. NASA's space shuttle program ran until 2011 when the shuttle Atlantis made its final flight. For over 30 years, NASA astronauts flew to and from space aboard space shuttles, making incredible leaps such as the construction of the International Space Station and the launch of the Hubble Space Telescope.

The space shuttle program also included tragic incidents with the Challenger and Columbia missions, showing NASA and the world just how dangerous space can be.

Russia launched a cargo mission toward the International Space Station today (Sept. 16), delivering the freighter spacecraft to orbit for a three-day rendezvous journey.

The robotic Progress 96 spacecraft lifted off atop a Soyuz rocket from the Russian-run Baikonur Cosmodrome in Kazakhstan today at 9:33 a.m. EDT (1333 GMT).

From engine ignition through solar array deployment on the spacecraft, the Progress 96 launch was completely nominal. It was "a flawless launch," said NASA's Rob Navias during the mission's livestream this morning, with "an excellent climb to orbit by the Soyuz booster."

Progress 96 is loaded with about 3 tons of food, propellant and other supplies for the astronauts aboard the International Space Station (ISS). The freighter will deliver this cargo three days after launch, if all goes according to plan. You'll be able to watch rendezvous and docking activities when the time comes.

The freighter will remain docked to the orbiting lab for about five months. It will then be loaded up with trash and sent down to a fiery death in Earth's atmosphere over the Pacific Ocean.

The Progress 94 spacecraft met this fate on Sept. 7, departing from ISS' Poisk module to make room for Progress 96.

Progress is one of four spacecraft that fly operational cargo missions to the ISS these days, along with Japan's HTV-X, SpaceX's Dragon capsule and Northrop Grumman's Cygnus. All but Dragon are expendable, burning up in our air when their time in orbit is up.

There are currently seven people living aboard the ISS — NASA astronauts Jack Hathaway, Jessica Meir and Anil Menon; the European Space Agency's Sophie Adenot, who last month became the first French woman ever to perform a spacewalk; and Pyotr Dubrov, Andrey Fedyaev and Anna Kikina of the Russian space agency Roscosmos.

Editor's note: This story was updated at 10 a.m. ET on Sept. 16 with news of successful launch.

NASA astronaut Victor Glover is now "astronaut emeritus." He's hanging up his spacesuit for a position he hopes can guide the future engineering and science leaders of tomorrow.

Glover, who served as pilot on NASA's Artemis II mission that flew around the moon in April, officially began his new role as executive advisor to Jeff Armstrong, president of the California Polytechnic State University (Cal Poly),on Sept. 1, and is stepping away from the majority of his duties at the space agency.

NASA announced on Sept. 9 that Glover, as well as Artemis II commander Reid Wiseman, are transitioning to emeritus status beginning this month, but are not retiring from the agency outright. Even astronauts who do fully retire from NASA are still retained "in the system," Glover told Space.com, "but I actually get to have a badge that is a little bit different. I can come back. I have a NASA email address. I still work closely with the agency. I'm considered a special government employee."

"It allows me to have just a slightly more robust and meaningful relationship with NASA," Glover said — but "more robust" won't necessarily equate to the same daily commitment. His role at Cal Poly will be full-time, according to the university, but he's not exactly going to be putting in typical work hours there either.

"We're still figuring it out," he said. "It's not going to be nine to five. I'm not a faculty member. I don't have a class I have to teach or a board that I oversee. It'll be where the school needs me the most and where I can highlight what great work they're already doing."

Glover's connection to Cal Poly runs deep. He's a Cal Poly alum who graduated with an engineering degree in 1999. A two-sport athlete, he wrestled for the university and played on its football team. And it's where he met his wife, Dionna, who also graduated from Cal Poly. The two have since raised four daughters, all of whom have either graduated or are currently attending their parents' alma mater. With Glover's multifaceted connection to the university, Cal Poly sees his potential contributions as equally diverse.

The university says that Glover, in his position as executive advisor, will work with the gamut of university leadership, including the president, provost and college deans. He will help "identify, develop and accelerate strategic initiatives, partnerships and philanthropy aimed at expanding the university's leadership in engineering, applied computing, aerospace, aviation, maritime, artificial intelligence, cybersecurity, autonomous systems and national defense," according to Cal Poly's statement.

How that will manifest into Glover's actual contributions is still being figured out. "There's just so much potential," he said, adding that he wants to serve in an additive role for Cal Poly where he can "get in and help, and do the most good."

Cal Poly has been undergoing a period of significant change and expansion over the past several years. This fall, for the first time ever, the university transitioned from a quarter system to a semester-based one. It also recently completed its integration with the former California State University Maritime Academy, whose Vallejo campus is now Cal Poly's Solano Campus and home to the Cal Poly Maritime Academy.

"They're hitting on all cylinders in so many areas," Glover said. "There's so many areas where Cal Poly is doing amazing things, and each of those things by themselves have been a big deal."

The university operates on a "Learn by Doing" philosophy, which emphasizes hands-on, real-world experience alongside classroom instruction. Glover credits his professional successes to this system, and his experiences over a decade at NASA have reinforced his belief in that kind of educational approach.

"Putting energy and time into building trust is just as important, or more important, as building technology, and so I think there's a lot of areas where my NASA experience will also feed back into Learn by Doing," Glover said. "I think everything I did at NASA has a place here."

"At NASA we do some pretty challenging things, pretty risky things, but we have a really strong scientific and technical understanding of what we're doing," Glover said. "That kind of risk-informed decision making is an important part of what we do here [at Cal Poly], whether it's professional development or helping these students to become the next generation of leaders."

Glover cited Charles Lindbergh's book "We," and its perspective on learning to fly a plane, as an example for Learn by Doing's effectiveness. "You teach yourself to fly," Glover said. "An instructor is really there to keep you from having ultimate mistakes. But you teach yourself to fly. It's something that you have to work out yourself. And I think that this school really understands that … We want to make sure that these students can critically think and analyze, but we also want to make sure that they can do the work with their hands."

Flying is something with which Glover has an extensive familiarity. Before he joined NASA in 2013, he was a U.S. Navy aviator and test pilot with 4,000 flight hours in more than 40 aircraft who flew 24 combat missions, though he is now best known for piloting NASA's Orion spacecraft around the moon on Artemis II.

Glover launched aboard Orion on NASA's Space Launch System (SLS) rocket on April 1 with three crewmates — Wiseman, NASA astronaut Christina Koch and Canadian Space Agency astronaut Jeremy Hansen. The quartet spent approximately 10 days aboard the Orion capsule and flew a course around the moon's far side. Their mission was the first to fly a crew to lunar space since Apollo 17 in 1972, and it captured the attention of millions across the world as the astronauts sent back views of the moon unlike any humanity had ever seen.

Artemis II was the first crewed mission in NASA's Artemis program, which has the ultimate goal of establishing a permanent base on the lunar surface. The next time Orion launches, on Artemis III, the spacecraft's crew will be tasked with testing out docking hardware with the program's lunar lander vehicles in Earth orbit. NASA is targeting mid-2027 for that mission. If it's successful, Artemis IV will follow in 2028 as the program's first lunar landing attempt, with subsequent missions with more crew and cargo to incrementally assemble an outpost on the surface of the moon in the 2030s.

As the only people to fly aboard Orion in space so far, the Artemis II crew's experience and insight into the spacecraft, and how future Artremis astronauts can best train to fly it, are invaluable to NASA — hence Glover and Wiseman's emeritus status.

Hansen, who trained at NASA's Johnson Space Center (JSC) and lived in Houston since his induction as a CSA astronaut in 2009, announced in July that he's stepping back from active astronaut duty beginning this month and moving back to Canada. On Sept. 8, the day before NASA made the announcement about Glover and Wiseman, Hansen posted a video on X stating that his Artemis II duties officially concluded on Sept. 2.

That leaves Koch as the only Artemis II crew member on an active astronaut roster, but Glover and Wiseman, as emeritus flyers, aren't out of the agency entirely. "With our experience flying Orion in space, the agency knows that we can still make a meaningful contribution to Artemis and human spaceflight in general, without having to be there full time," Glover said. "We can still support our colleagues and their families and the mission while we go off and pursue other other opportunities."

Supporting other astronauts on NASA's roster, and the teams that run the missions, are the parts of the job that Glover enjoyed the most. "[The emeritus status] allows us to still support our colleagues, which is the best part of being an astronaut. It's not flying in space," Glover said.

"I told [NASA leadership], ‘Nothing has really changed,'" Glover said. "If they call me and say, ‘Hey, we need this,' they can count on me to be there because they are so fantastic. I will always be there to carry the water for them when they need it."

Though he'll still be helping astronauts prepare for future missions every now and then, Glover said his own spaceflight days are behind him. Glover had flown to space once before, prior to Artemis II, as pilot of SpaceX's Crew-1 mission to the International Space Station (ISS). Glover spent 168 days in orbit on that stint, serving as flight engineer for Expeditions 64 and 65, and completed four spacewalks.

"I didn't make this move planning to go back to space," Glover said. "I was pretty satisfied after my first space mission, so I don't have this hole in my heart that needs to be filled by going to space again."

A few NASA astronauts who've left and moved on to the private sector have ended up going back to space, like Peggy Whitson, who retired from NASA in 2018 before joining Axiom Space and later commanding the company's Ax-2 and Ax-4 private astronaut missions to the ISS. But Glover doesn't see a move like that in his future.

"If I wanted to go to space, I would have stayed at NASA. It's the gold standard," Glover said. "I love our corporate partners and what they're doing. There's some really amazing things, including what Jared Isaacman himself has done … But I would have stayed at NASA full time as an active astronaut if I was trying to go back to space."

Isaacman was sworn in as NASA administrator in December 2025. His spaceflight experience came before that: In September 2021, he commanded SpaceX's Inspiration4 mission, the first all-civilian orbital spaceflight, and later performed the first commercial spacewalk during the private Polaris Dawn mission in September 2024.

In fact, Glover said it was harder walking away from his career flying fighter jets than it was to walk away from the opportunity to maybe one day fly in space again. Harder still might be leaving behind the place he's called home for more than a decade, but ultimately he said it was an easy choice. He's lived in Houston and worked at JSC since his selection into NASA's astronaut class in 2013, but expects he and his family will make the permanent move to the West Coast, to be closer to Cal Poly.

"One of the reasons why this was just such an easy decision to make is that both NASA and Cal Poly … and everybody understands that we need time to get used to this new reality, and they're all giving us a lot of grace and space as we just kind of figure out what the right rhythm, what the right ops tempo is," Glover said. He thinks he and the family will make the move sometime after the New Year.

In the meantime, though you may not see him quite as much on NASA's social media channels, he has made a few appearances in posts on his daughter Maya's TikTok profile. In posts celebrating his return from the moon and recent career shift, Glover can be seen performing dance routines with his family — but don't bother refreshing your feed to load more any time soon.

"Don't expect to see a whole lot more of that, because I would do anything for my kids, but you know, well, I guess almost anything for my kids," Glover said jokingly. When asked which was harder to train for, between piloting Orion and the dance moves, he said, "Oh, clearly the dance moves."

NASA astronaut Jessica Meir just shared some tips for controlling curls in the tough environment of microgravity — and it was a big deal for curly-haired people like me.

Meir's hair-care advice came Wednesday (Sept. 9) in a 5.5-minute video she posted to X from the International Space Station (ISS), where everything floats and "where curls are even more free to be what they want to be," the Expedition 75 astronaut wrote.

And if you think all this talk about hair care sounds frivolous, take it from a fellow curly: the representation matters. More on that in a moment, but first, let's see how Meir takes care of her curly hair in microgravity.

According to Meir, washing in orbit requires no-rinse shampoo, especially focusing on the scalp, where sweat and salt build up. She has less access to hair products than we do here on Earth, as you would imagine, so she keeps it simple: a careful squeeze of her pouch of water, then working the expelled water along her hair roots, and also rubbing it on the scalp. Meir then uses a "dedicated T-shirt" to dry her hair, which she described as thick as well as curly.

In between treatments, Meir avoids brushes (for pretty obvious reasons of frizz) and uses her hands and fingers instead to "work" her hair. Luckily, humidity is not much of an issue on the ISS, but she does use leave-in conditioner: "My Earthly 3a curls become more like 3c," she said. Meir has been on the ISS since February, and she said she's looking forward to having an actual shower when she gets back home to Earth.

OK, so about that representation. My editor asked me to talk not only about Meir's video but also my own connections to her words, which brings up some teenage angst. In the 1990s, I was (then, as now) a curly-haired person who was just (bitterly) old enough to remember all the curly rock stars of my childhood in the '80s. But dare to wear curls in my school in like, 1994? As if! Lame!

All the young women around me were rocking the flat-haired "Rachel from 'Friends'" look that would take thick-haired curlies like me forever to achieve. I couldn't be bothered — I like sleep! Which apparently was enough for my classmates (of any gender) to deliver unprintable and sometimes racist insults, or to hide their faces from me because I was "ugly," or to spread rumors that I carried hair lice, and so forth. I couldn't believe it; other kids were sporting awesome and stand-out 'dos like mullets and mushroom cuts, so what was wrong with curls?

To be clear, as a 40-something I now have perspective: I later learned that some of my classmates had complex (even tragic) issues of their own contributing to the bullying, and I have no idea how other kids in my classes fared with their hairdos. The real lesson learned is that representation matters, inclusivity is possible and inclusivity matters across multiple dimensions. While looks may not sound important, at first glance, they really are: curly hair is a dimension of diversity. (I know I am just one female voice, with white U.K. ancestry; other people with curly hair will have different perspectives.)

So, back to the curly-hair-space-care routine: as a fellow curly, can I confirm that it stands up? Yes it does. While I'm no astronaut like Meir, I can offer you an analog: the two weeks I spent in 2014 at the Mars Society's Mars Desert Research Station in rural Utah, during which my crew was able to shower every two days, if we were lucky.

On that simulated Red Planet mission, I also used no-rinse shampoo to save on water, only combed (never brushed) my hair when it was wet, and mostly wore it bun-style to protect the curls in the meantime. While it took me two showers to feel normal when I at last reached a hotel room with running water, my hair bounced — so to speak — back quickly. That shows my curls are resilient, and since my 20s I've felt lucky to have them; my hair takes me a minimum of work or styling besides a quick wash and comb, and — as long as I don't touch my hair after it's wet — it's happy.

And to all those kids teasing me back in the day, allow me a moment of moon joy: NASA's Christina Koch sported curly hair during NASA's Artemis II lunar mission earlier this year. Koch herself, by the way, later spoke about her moon-mission braids at an event in my literal city in Canada (as, speaking of representation, I'm Canadian). Yes, of course there was more to this historic mission than hair: I covered Artemis II's science and activities at numerous in-person events for three-plus years, and some of its crew members for 17 years. But to see curls on a person looping around the moon? Bonus.

Every curly-haired person's experience is different, however, so I'd like to hear from you. There's a comment section with this article to chat about microgravity (or analog) curly-hair care, other curly-haired astronauts, or similar topics. Let us know your thoughts.

Rocket Lab still holds out hope that it can build NASA's next Mars orbiter.

The agency picked Blue Origin for that job earlier this month, awarding Jeff Bezos' spaceflight company $700 million to develop, launch and operate the Mars Telecommunications Network (MTN).

Today (Sept. 11), however, Rocket Lab announced that it has challenged that decision, filing a formal protest with the Government Accountability Office (GAO).

"NASA's award decision appears to be inconsistent with the eligibility criteria mandated by Congress. In addition, the agency’s punitive review of Rocket Lab's technical volume was inconsistent, making incorrect assertions and conclusions," Rocket Lab said today in an X post that laid out its argument.

"Procurement standards exist to ensure fair competition and protect public investment," the California-based company added. "We are pursuing this review to ensure those standards are upheld for critical infrastructure that will underpin American exploration at Mars for decades to come."

As its name suggests, the MTN orbiter will serve as a communications link between mission controllers here on Earth and other NASA spacecraft studying the Red Planet. Just two agency orbiters fulfill that relay role these days, and both are quite old: Mars Odyssey launched in 2001, and the Mars Reconnaissance Orbiter lifted off in 2005.

NASA had been eyeing a new Mars telecom orbiter for years and finally got Congressional funding for it in July 2025 — $700 million, to be precise. The agency issued a request for proposals this past May, drawing considerable interest from the private sector.

Blue Origin and Rocket Lab were widely considered the front-runners, and NASA ended up going with Blue. The award calls for the company to deliver MTN (which, despite the "network" in its name, is a single spacecraft) to NASA no later than Dec. 31, 2028. It's expected to be up and running at the Red Planet by 2030.

Blue Origin has been in Rocket Lab's shoes before, and has behaved similarly. Bezos' company filed a protest with the GAO in 2021 after NASA picked SpaceX to provide the first crewed moon lander for the agency's Artemis program.

The GAO denied the protest in July of that year. Blue Origin then sued NASA but lost in court in November 2021. The story has a happy ending for the company, however: NASA decided to select a second Artemis lander as well, and Blue Origin won that contract in 2023. We'll see how this story plays out for Rocket Lab...

LINK, the satellite sent to boost the orbit of NASA's Swift Observatory, may have had to give up on its mission, but LINK's manufacturer and operator Katalyst Space hasn't completely abandoned the spacecraft to its cosmic demise.

NASA called off LINK's mission to rendezvous with its Neil Gehrels Swift Observatory when the specialized probe encountered a thruster control issue. LINK was delivered to orbit on July 3, aboard an air-launched Northrop Grumman Pegasus XL rocket, but began to spin uncontrollably about three weeks after reaching space. Swift's orbit began decaying faster than expected last year, due to increased solar activity, and LINK was designed to rendezvous with Swift, grapple it, and then raise the observatory to a more stable altitude.

LINK's Swift Boost mission was considered a "Hail Mary" attempt from its onset. NASA's discovery of Swift's swiftly decaying orbit meant the Arizona-based Katalyst had less than a year to design, manufacture and test LINK before needing to launch. Now, with both of their missions on the short-track for destruction, NASA and Katalyst are left both trying to get the most out of their spacecraft with the time each has left.

LINK's failure means Swift is destined to burn up in Earth's atmosphere before the end of the year, and LINK itself is expected to fall to the same fate within just the next few weeks. But the probe's inability to save Swift hasn't stopped Katalyst from getting as much data from LINK as it can. Though a closer rendezvous is no longer in the cards, the spacecraft managed to successfully fire all three of its electric propulsion thrusters and adjust its orbit to fly within 7.5 to 9 miles (12 to 15 kilometers) of Swift. Katalyst was also able to deploy all three of LINK's robotic arms, which would have been used to grapple Swift for its orbital adjustment.

Swift launched in November 2004, and has been studying high-energy phenomena like gamma-ray bursts, supernovas, black-hole ejections and fast radio bursts across the universe for more than 20 years. Despite its impending demise, two of Swift's three science instruments — its X-ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT) — were turned back on in late August after being shut down in February to minimize atmospheric drag on the spacecraft in anticipation of LINK's now defunct orbital boost efforts.

With the option for LINK to raise Swift's orbit now off the table, Katalyst and NASA are working to perform whatever technology demonstrations are possible aboard the spacecraft, in the hopes the technology can be used to service other satellites on missions in the future.

Three of NASA's Artemis II astronauts are starting off the school year with new assignments.

Artemis II commander Reid Wiseman and pilot Victor Glover, both NASA astronauts, will transition into "emeritus status" in September, the space agency announced on Wednesday (Sept. 9). Meanwhile, Canadian mission specialist Jeremy Hansen shared a video on X on Tuesday (Sept. 8) concerning his already-announced transfer from active duty to reserve status in the Canadian military.

The fourth Artemis II astronaut, NASA mission specialist Christina Koch, appears to still be on active duty, as no announcements have been made saying otherwise.

The Artemis II quartet flew around the moon in April, becoming the first people to go beyond low Earth orbit since 1972. The historic journey was widely expected to be the last step in active astronaut duty for at least some of the mission's four astronauts, especially Hansen, who had waited for a flight assignment for 17 years in part due to how Canadian Space Agency funding is allocated. (Robotics provided by the CSA form a minority share of international space partnerships with NASA, and astronaut flight rates are tied to funding.)

The Artemis II astronauts made a series of public appearances together this summer, culminating on Aug. 28 when President Trump awarded them the Congressional Space Medal of Honor. Hansen was only the second non-American to receive the award, which had previously been given to just 30 astronauts total.

While NASA's Wednesday announcement about Glover and Wiseman did not explicitly state that the duo are exiting active astronaut duty, their new role is described as allowing the astronauts to assist NASA as consultants and "individuals with a high degree of technical and professional knowledge," while allowing them to do other things.

The two astronauts are expected to help NASA plan future Artemis program missions. "I'm grateful they will continue sharing what they learned with our astronauts, flight controllers and engineers as we prepare for Artemis III in 2027 and the missions that follow," NASA administrator Jared Isaacman said in the statement.

Glover, who also retired from the U.S. Navy recently, will now assume a full-time role at his alma mater, California Polytechnic State University in San Luis Obispo, which has aerospace and space programs. The news was announced by the university on Wednesday, but the position took effect on Sept. 1. Glover will be an administrative leader providing advice to senior leadership on education, research and workforce strategies, according to Cal Poly.

"The most meaningful moments of my NASA career were supporting astronauts and their families through missions, and mentoring interns and new hires as they began their own journeys in technical and public service," Glover wrote Wednesday in a post on X about the career change.

Wiseman did not share any specific updates about his career plans on social media. The astronaut also exited active astronaut duty temporarily between 2020 and 2022 when he was chief of the astronaut office for NASA, a role that precludes flying in space as the chief is involved in flight assignments. Wiseman left that role and resumed active astronaut duty before being assigned to Artemis 2, which occurred shortly before the public announcement of the mission's crew in April 2023.

"NASA gave me tremendous responsibility, supported me through two space missions — and my time as chief astronaut — and was always there for my family when we needed it most," Wiseman said in the NASA statement about his career change. "I'm thrilled to continue serving future missions and programs through the emeritus program."

Hansen's Artemis 2 duties officially concluded on Sept. 2, according to his X account, and the astronaut — who has been based out of Houston since 2009 — posted a new video of himself Wednesday walking in the woods in Canada. Hansen said he has retired as a colonel with the Royal Canadian Air Force and is now a reservist working with 3 Canadian Space Division, which is essentially Canada's Space Force.

"The intention of that is to continue to serve Canada and government — the Canadian Space Agency — when it makes sense, to help us take advantage of some of the extraordinary opportunities that are before us right now," Hansen said in the video, adding that he will divulge more details about that work shortly.

Hansen also said he accepted a role as honorary national president with the Canadian military's Air Cadet League of Canada, which the astronaut has often said helped equip him with both flying and leadership skills when Hansen was growing up.

Additionally, Hansen pledged to "continue to share the moon joy" both as an individual and with his crew. For example, he recently joined a Canadian keynote-speakers bureau in which he plans to speak about how to accomplish personal "moonshots." In October, Hansen will also co-release "Earthrise: A Canadian Astronaut's Journey Into Deep Space" (HarperCollins Publishers, 2026) — a book that discusses his career and Artemis 2 — which he co-wrote with Canadian author John Larsen.

On Aug. 30, the Nancy Grace Roman Space Telescope launched into space aboard a SpaceX Falcon Heavy rocket — then, after completing their job, the rocket's boosters safely landed back on Earth. Watching the events unfold, Space.com's Chelsea Gohd caught one of these beautiful landings on camera as onlookers at NASA's Kennedy Space Center watched in awe.

What is it?

The Roman Space Telescope is NASA's next great observatory, meant to revolutionize how we view the cosmos. Equipped with instruments like a coronagraph that can directly image exoplanets and a Wide-Field Instrument (WFI) that has a massively wide field of view, it's designed to work with big names like the Hubble Space Telescope and James Webb Space Telescope and reveal our universe's intricacies on a grand scale.

But to get to space, like any other space telescope, it needed a rocket to ferry it there. In this case, that was SpaceX's Falcon Heavy rocket. Falcon Heavy is about 230 feet (70 meters) tall and can lift nearly 141,000 pounds (64 metric tons) of payload to low Earth orbit. And importantly, Falcon Heavy's two boosters are reusable.

After launching a payload to space, the boosters split and each lands back on Earth in an upright position. In the image above, Gohd captured one of those boosters landing in the distance.

Why is it incredible?

Though we hear about it so often, there is something undeniably dreamlike about living in a time when a rocket can land its parts back on Earth so precisely. I was also there for the launch of the Roman Space Telescope in Florida, and it was breathtaking to watch such a huge piece of equipment navigate mid-air and straighten itself before landing. The crowd in the picture was equally astonished while the event unfolded.

My mother texted me just after she watched the Roman Space Telescope launch live online, exclaiming that the booster's landing looked just like a taxi returning to its station, getting ready for the next task. I hadn't thought about it that way before, but she was correct.

One of the boosters that participated in Roman's launch landed at Landing Zone 2 and the other hit the ground at Landing Zone 40. As NASA explained in a statement, one of these boosters carried out its very first mission while the other was on its third.

Now, the next spectacle to take our breath away will be Roman's very first images of the universe. Those are expected to drop next year.

Like most of their compatriots here on terra firma, the three Americans living off Earth will get to put their feet up today (Sept. 7).

NASA astronauts Jack Hathaway, Jessica Meir and Anil Menon will get Labor Day off aboard the International Space Station (ISS), the agency said on Friday (Sept. 4). European Space Agency astronaut Sophie Adenot, the first French woman ever to perform a spacewalk, will also be off duty.

However, the three Russian cosmonauts living on the ISS will have to clock in as usual.

The trio — Pyotr Dubrov, Andrey Fedyaev and Anna Kikina — "will be busy monitoring the Progress 94 resupply spacecraft when it undocks on Monday, packed with trash and obsolete gear, from the Poisk module," NASA officials said in an update on Friday.

"It will be replaced by the Progress 96 resupply spacecraft after it launches from Kazakhstan's Baikonur Cosmodrome on Sept. 9 for an automated docking two days later to Poisk’s vacated port," they added.

Adenot, Feyaev, Hathaway and Meir arrived at the ISS in mid-February on SpaceX's Crew-12 mission. Dubrov, Kikina and Menon are relative newcomers, reaching the station aboard a Russian Soyuz spacecraft on July 14.

NASA astronauts on long-duration missions to the ISS generally work a relatively normal schedule, getting weekends and major holidays off. Such downtime is crucial to mission success, as it helps the spaceflyers stay happy, healthy and productive.

They may not be able to mark the holidays in exactly the same ways we do here on Earth, however. For example, the astronauts won't be grilling any hamburgers or hot dogs today, as open flames are verboten on the ISS.

As today's schedule shows, international crewmates do not always have the same days off in orbit. But they try to celebrate major holidays like Christmas together, both to cement the bonds that exist between them and to take the sting out of being so far away from family and friends.

After nearly eight years traveling through the inner solar system, the trailblazing BepiColombo spacecraft has finally begun its arrival at Mercury.

The joint European Space Agency (ESA)-Japanese Aerospace Exploration Agency (JAXA) mission reached a major milestone today (Sep. 3), entering its arrival phase at one of our sun's least-studied planets. BepiColombo's Mercury Transfer Module (MTM), the main power and propulsion system that has ferried a dual stack of planetary probes through space for nearly eight years, released its payload to kick off a sequence of operations that will ultimately place the two spacecraft in Mercury's orbit.

The separation left ESA's Mercury Planetary Orbiter (MPO) and JAXA's Mercury Magnetospheric Orbiter, known as Mio, together for their final approach, which will take about six more months. "It will basically be a new mission starting today," said Bruno Sousa, ESA's head of operations definition and engineering, during today's mission livestream.

BepiColombo launched aboard an Ariane 5 rocket from Europe's Spaceport at the Guiana Space Center in Kourou, French Guiana, on Oct. 19, 2018, beginning a journey that was expected to take about seven years. To assist its plunge sunward, the spacecraft's trajectory has included one flyby of Earth, two of Venus and six of Mercury, as it has shed more and more gravitational energy during to slow its approach to the system's innermost planet.

"It's one of the most complicated missions we have ever flown," Sousa said. The mission was made even more complicated in April 2024, when a solar panel issue reduced the available power for MTM's electric thrusters. Engineers devised a lower-thrust trajectory that saved BepiColombo's mission but delayed its Mercury arrival from December 2025 to November 2026.

Today's maneuver doesn't place BepiColombo in orbit around Mercury quite yet. MPO and Mio will spend the next several weeks navigating toward the planet ahead of orbital insertion on Nov. 21. "Arriving to Mercury is not as simple as other missions that do a big maneuver and they are there," said Elsa Montagnon, BepiColombo's operations manager. "In our case, it's going to be six months of continuous activities."

The Nov. 21 arrival will begin a sequence of 16 maneuvers to progressively lower and reshape BepiColombo's orbit. Mio is scheduled to separate from MPO around Dec. 9 and settle into a highly elliptical polar orbit. MPO will jettison Mio's MOSIF sunshield (Magnetospheric Orbiter Sunshield and Interface Structure) on Dec. 16, then continue lowering its own altitude before reaching its own polar orbit on March 10, 2027.

BepiColombo is scheduled to begin science operations on April 6, 2027, with MPO and Mio studying Mercury simultaneously from complementary orbits. MPO will focus on Mercury's surface composition, geology and planetary interior, while Mio will investigate the planet's magnetic field and its interaction with the solar wind.

Today's separation took place at 8:00 a.m. EDT (1200 GMT), but confirmation of that event didn't come for more than an hour following its scheduled execution. Acquisition of signal from BepiColombo came just before 10 a.m. EDT (1400 GMT), followed by a positive telemetry reading indicating the spacecraft was where it was supposed to be.

"I'm again extremely relieved," Montagnon said. "That the telemetry comes exactly at the moment we expect it, and that we see in the telemetry that the configuration of the spacecraft is the correct one," she said, "this is the best case scenario."

Blue Origin will build NASA's next Mars orbiter.

The agency announced on Tuesday (Sept. 1) that it has selected Jeff Bezos' spaceflight company to develop the $700 million Mars Telecommunications Network (MTN), which is expected to be up and running at the Red Planet by 2030.

"The award marks a milestone in NASA's strategy to expand communications and navigation services beyond Earth and the moon, establishing the foundation for sustained exploration of Mars in the coming decades," NASA officials said in a statement on Tuesday.

As its name suggests, the MTN — previously known as the Mars Telecommunications Orbiter — will primarily serve to aid NASA science missions rather than gather data of its own.

The MTN is "a next-generation communications system that will enable reliable, high-bandwidth communications and navigation services for current and future Mars missions," NASA officials said in the statement.

The need for such a data-relay craft is expected to become acute in the coming years as NASA's fleet of current Mars orbiters ages and the agency works to prepare the Red Planet ground for crewed missions in the late 2030s or early 2040s.

At the moment, just two NASA orbiters relay data and commands between the agency's Curiosity and Perseverance Mars rovers and their handlers on Earth — Mars Odyssey and the Mars Reconnaissance Orbiter, which launched in 2001 and 2005, respectively. The European Space Agency's Mars Express and Trace Gas Orbiter spacecraft help out as well.

All four of these orbiters are gathering science data of their own, however. The MTN will not have a split focus; it will be a dedicated communications craft.

NASA got $700 million for a Mars telecom orbiter in July 2025, when Congress passed a budget reconciliation bill. The agency laid out requirements for the spacecraft in February of this year, then issued a request for proposals in May.

Blue Origin and Rocket Lab were viewed as the front-runners for the contract, and both pushed hard for it, touting their bona fides and expertise.

Blue Origin won out in the end, however. The company will base MTN on its Blue Ring spacecraft platform, which it describes as "an all-in-one, high-powered hybrid solar electric and chemical propelled spacecraft that provides unmatched mission maneuverability, versatility, and capacity at dramatically lower profile costs."

Blue Ring has not flown a mission yet, but a prototype version of it went to space on the first-ever launch of Blue Origin's powerful New Glenn rocket in January 2025. Though Blue Ring can fly on other rockets as well, MTN will presumably launch on a New Glenn; the newly announced NASA contract calls for Blue Origin to "design, develop, integrate, launch and operate" the Mars telecom mission.

The contract calls for Blue Origin to deliver the spacecraft to NASA no later than Dec. 31, 2028.

Two astronauts replaced a spacecraft docking aid and a video camera during a successful spacewalk outside of the International Space Station on Tuesday (Sept. 1).

NASA astronaut Jessica Meir and ESA (European Space Agency) astronaut Sophie Adenot got through most of the tasks set out for them even in light of Adenot's spacesuit developing a mobility issue late in the extravehicular activity (EVA), which lasted six hours and 49 minutes.

After beginning the spacewalk from the U.S. Quest airlock at 8:40 a.m. EDT (1240 GMT), Meir and Adenot set about the first and most important activity of the outing: replacing the planar deflector on the forward port of the station's Harmony Node 2. The retroreflector is used to support navigation during rendezvous and docking operations by visiting spacecraft. The older reflector that they replaced had become coated in thruster residue from earlier spacecraft arrivals and departures.

They also replaced the Camera Port 3 (CP3) high-definition (HD) camera on the station's truss.

"And it's off!" reported Meir after freeing the spent camera assembly that was swapped out for spare. Her words were met by applause in Mission Control at NASA's Johnson Space Center in Houston.

"That worked, great!" she said.

From there, Adenot headed off to continue an ongoing scientific study by swabbing areas on the exterior of the airlock and her gloves for possible microorganisms. Meir, meanwhile, rode one end of the Canadarm2 robotic arm to a site near the Alpha Magnetic Spectrometer (AMS), torquing 46 bolts in preparation for future maintenance of the particle physics detector.

Meir also relocated power and thermal jumper cables and an articulating portable foot restraint for use on a later spacewalk.

There were some other tasks planned, time permitting, but toward the end of the EVA, Adenot reported losing mobility in her left shoulder joint. Erring on the side of caution, Mission Control called for Adenot to wait where she was until Meir could follow her back to the airlock.

Once there, Meir was able to unzip a portion of Adenot's extravehicular mobility unit's (EMU's) upper arm assembly to inspect what was happening. In doing so, she freed the kink that had limited Adenot's motion.

"I think it was where the cable got caught in between the shoulder MLI [multi-layer insulation] and the rotation [joint]. I don't think it was held up by anything but some friction," said Meir.

The two Expedition 75 crewmates then proceeded back into the airlock to complete the EVA at 4:29 p.m (2029 GMT).

Tuesday's spacewalk was Meir's seventh and Adenot's third. Meir, who has a total of 49 hours and 22 minutes on EVA, now ranks third among all women astronauts at NASA for total number of spacewalks. She trails only Peggy Whitson with 10 and Suni Williams at 9.

Adenot now has spent 19 hours and 42 minutes working in the vacuum of space.

This spacewalk was the 284th supporting the International Space Station's assembly, maintenance and upgrades. It was the seventh spacewalk this year, fifth EVA for Expedition 75 and the sixth all-female spacewalk in history.

NASA's next big space telescope is not only meant to unlock some of the mysteries of dark energy. It also is a pioneer in the naming of missions.

Scientific American recently said that the observatory, which launched on Aug. 30, is the first ever space telescope ever named after a real-life woman: American astronomer Nancy Grace Roman, who supported development of the iconic Hubble Space Telescope and was NASA's first head of astronomy in the 1960s.

The story is very different when it comes to men. For example, NASA's "Great Observatories," which launched between 1990 and 2003, were all named after famous U.S. male astronomers or physicists: the Hubble Space Telescope (Edwin Hubble), the Compton Gamma-Ray Observatory (Arthur Compton), the Chandra X-ray Observatory (Subrahmanyan Chandrasekhar) and the Spitzer Space Telescope (Lyman Spitzer).

Indeed, relatively few spacecraft of any kind have borne female names over the years — and most of the ones that did were not honoring actual, real-life people.

For instance, a number of missions with female names took them from mythology (e.g., NASA's Europa Clipper and China's Chang'e moon probes). Others used female names not attached to particular individuals (such as NASA's Clementine moon mission, and the European Space Agency's LISA, which is an acronym for "Laser Intraferometer Space Antenna.")

A notable exception is Sojourner, the mini-rover on NASA's Mars Pathfinder lander mission that was made famous again by the 2015 film "The Martian;" it's named after Sojourner Truth, a Civil War-era abolitionist. Sojourner's name was selected in 1995 from a worldwide naming contest for students and suggested by 12-year-old Valerie Ambroise of Bridgeport, Connecticut. Some other notable examples of missions honoring real-life women include:

• ESA's long-delayed ExoMars rover Rosalind Franklin, which is now set to launch to Mars in 2028. It's named after a British scientist who contributed to discovering the structure of DNA. (Part of the rover's mission is to analyze potential biosignatures on the Red Planet's surface.)
• The Cygnus International Space Station (ISS) resupply program, which is managed by Northrop Grumman. Multiple Cygnus freighters have been named after female NASA astronauts, including Janice E. Voss, Sally Ride and Kalpana Chawla, and one of them honored the American mathematician and "hidden figure" Katherine Johnson.
• Satellogic's ÑuSat/NewSat series. It has commonly named satellites after female historical figures in science, such as Black American chemist Alice Ball, Polish physicist-chemist Marie Curie and Australian radio astronomer Ruby Payne-Scott.
• Canada's GHGSat has a program in which employees name the company's Earth-orbiting satellites after family members, which has generated names from real-life people like Eleonore and Penny.
• The U.S. Space Force nicknamed its GPS III Space Vehicle-08 "Ms. Creola Katherine Johnson," another nod to the mathematician

What this means

Throughout history, the names of ocean-going ships — ships on the water, not spaceships — often have associations with women. The U.K.'s Imperial War Museums (IWM) suggests that women's names are used due to two traditions. The first is that, very generally speaking, the word "boat" is a "female" word in some languages that use gendered nouns, but that is by far not universal, even among the imperial sailing powers of the 1400s to 1600s.

The second association, which seems more likely, is the notion of a mother, goddess or similar "female figure" guiding a crew, which we see in theaters right now with "The Odyssey:" Athena helps Odysseus, reflecting the ancient Greek epic story. (For example, figureheads — sculptures on sailing ship prows — were often, although not always, carved in the likeness of women, Royal Museums Greenwich states.)

There are famous sailing ships with female names that many Americans can cite, such as the nicknames for the three Spanish ships — the Niña, Pinta and Santa María — used by Christopher Columbus during his famed first voyage to the New World in 1492.

"There's always been a tradition to name ships — and oftentimes after women," Valerie Neal, emerita curator in the Smithsonian National Air and Space Museum's department of space history, told Space.com. Neal's research includes extensive work on female astronauts.

The U.S. space program has historically leaned upon mythological names of both genders for its missions, she noted, citing the Mercury, Gemini and Apollo human spaceflight programs as examples of male monikers. These days, Neal added, the education system is less tilted toward introducing children to old Greek or Roman myths, which may explain why it's now more common to name missions after real-life individuals.

In the 1970s and 1980s, for example, "there was a big debate at the time of the space shuttle naming whether to name the space shuttles after historic figures, or after concepts," Neal said. "One idea was even after Native American tribes." (For example, Tafuna High School in American Samoa recommended the name "Hōkūle'a" for shuttle, as noted in NASA's 1991 monograph "From Ship to Shuttle: NASA Orbiter-Naming Program")

The space shuttles were ultimately named Columbia, Challenger, Discovery, Atlantis and Endeavour after "historic ships of exploration," Neal said. You can read more about the origins of those names in this piece by The Space Foundation.

The Cygnus spacecraft "USS Janice Voss," which flew to the ISS in 2014, was the first U.S. orbital mission known to Neal to be named after a woman. "She had had an affiliation with the Orbital Sciences Corporation, and so they wanted to honor her," said Neal, referring to a previous company that managed the Cygnus program.

The flock of Cygnuses named after women — at least six of them, according to Neal — is "a good sign that people are starting to think of contemporary figures, or more contemporary, [and] naming spacecraft as a tribute to them, and to their contributions in science and exploration and discovery."

Naming a flagship space telescope after Nancy Grace Roman is another good sign, of course. And choosing her for this honor makes sense; she was in "a class by herself — because her name is so directly associated with astronomy and large space telescopes" like Hubble, Neal said.

"It is recognizing her significance in the history of space exploration as a leader who made so much possible, through her own work as an astronomer, but then as an administrator and manager at NASA made possible the orbiting solar observatories, the orbiting astronomical observatories — and then Hubble and the other great observatories that followed."

Roman's name on the telescope, she added, is "elevated" because "her name coincides exactly with the spacecraft and its purpose, whereas the names of the astronauts that are attached to the [ISS] resupply missions … not all of them had any connection to the International Space Station. Several did, but not all."

Neal said she's hopeful that more women will see their names attached to space missions, including both those historical astronomers who saw "their bosses were getting all the credit" as well as the numerous non-male scientists making impacts in the field today.

"I think it's entirely possible that, in time, there will be another major observatory named for a woman," Neal added. She noted that recommendations from the science community every 10 years form the basis of new space missions, and that the next such "decadal survey" in astrophysics is expected to wrap up around 2030.

In the nearer term, NASA is considering ideas such as an ultraviolet telescope, an advanced X-ray imaging satellite, and the Habitable Worlds Observatory for launch in the 2030s or early 2040s, presenting more opportunities to attach female names to flagship space missions.

Sidebar: Female mission names

With thousands of flown or planned missions to space, and numerous parts making up each spacecraft, it is difficult to compile a comprehensive list of probes or instruments that have had female names. The following is therefore a partial list, though an extensive one. In no particular order, it includes:

• Telescopes/observatories: NASA's Roman, ESA's Gaia, NASA's Pandora, the British-American Ariel V telescope, ESA's NewAthena, ESA's Ariel, ESA's LISA, NASA's TESS (Transiting Exoplanet Survey Satellite).
• Human spacecraft: Mercury Aurora 7, SpaceX's Crew Dragon Grace.
• Satellites/ISS missions: ESRO-1A and 1B's nicknames of Aurora and Boreas, multiple Cygnus ISS resupply spacecraft, much of the Satellogic NuSat/NewSat constellation, several GHGSat spacecraft, Space Force's GPS III Space Vehicle-08 (nicknamed Ms. Creola Katherine Johnson), and the Russian Resurs-DK1 satellite's multinational cosmic-ray module PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics).
• Moon: China's Chang'e series, the Soviet Union's Luna series, NASA's Artemis program and missions, Intuitive Machines' IM-2 lander Athena, JAXA's Selene/Kaguya, NASA's Clementine, the NASA ARTEMIS moon-orbiting probe.
• Venus: ESA's Venus Express, the Soviet Union's Venera series.
• Mars: ESA's Rosalind Franklin rover, NASA's Sojourner rover, JAXA's failed Nozomi orbiter.
• Jupiter/moons: NASA's Juno, NASA's Europa Clipper.
• Asteroids: NASA's Lucy, ESA's Hera.
• Other hardware: Some spacecraft/rocket parts have female names (e.g. the US military's Juno II rocket, Firefly Aerospace's Miranda engine, ESA's Europa and Ariane rockets).

The following at first glance appear to have female names, but either were not confirmed before this story's deadline or were confirmed to have other origins:

Repairing an engineering marvel like the International Space Station is no easy feat by itself, but it's even more impressive when it's done 250 miles (400 kilometers) up.

What is it?

In this photograph, European Space Agency (ESA) astronaut Sophie Adenot works on the exterior of the International Space Station on Aug. 25, 2026.

The photo was taken while Adenot and NASA astronaut Anil Menon were conducting a 6.5-hour spacewalk, or extravehicular activity (EVA), to replace one of two Space-to-Ground antennas on the outside of the ISS.

This was the second EVA that Adenot and Menon performed to replace the antenna. During a previous spacewalk a week earlier, the pair ran out of time before the new antenna could be installed.

With that first spacewalk, Adenot became the first woman from France to ever conduct an EVA.

Why is it incredible?

It can be hard to conceptualize just how high up the ISS orbits until you see a photo like this one; few people on Earth have ever flown as high as 250 miles (400 km), so that altitude can feel a bit abstract. Seeing an astronaut like Adenot clinging to the space station with the clouds and blue oceans of Earth below puts things into perspective.

At that height, the ISS orbits at quite a high rate of speed. The orbital laboratory zips around Earth at 17,500 mph (28,000 kph), meaning it circles the planet 16 times a day. This photo was taken on day 194, or orbit 3010, of Adenot's mission, which began in February when she launched to the ISS as part of NASA's Crew-12 mission.

Two astronauts will conduct history's sixth all-female spacewalk today (Sept. 1), and you can watch it live.

NASA's Jessica Meir and Sophie Adenot of the European Space Agency will venture outside the International Space Station (ISS) at around 8:30 a.m. EDT (1230 GMT) on an excursion expected to last about 6.5 hours.

You can watch it here at Space.com, courtesy of NASA, or directly via the agency. Coverage will start at 7:00 a.m. EDT (1100 GMT).

During today's spacewalk, Meir and Adenot "will replace a retroreflector on the forward port of the space station's Harmony module to support spacecraft navigation during rendezvous and docking operations," NASA officials said in a media advisory.

"After installing the reflector, the crew will work to install jumper cables for the data-relay systems, prepare the Alpha Magnetic Spectrometer's radiator for future maintenance, and replace a high-definition camera on the station's truss," they added.

(The Alpha Magnetic Spectrometer is a $2 billion particle physics experiment mounted to the exterior of the ISS that studies cosmic rays and hunts for mysterious dark matter, among other tasks.)

Adenot will be "crew member 1" on today's spacewalk and will wear a suit with red stripes, NASA officials said. Meir will wear an unmarked suit and serve as "crew member 2."

It will be the third spacewalk for Adenot, who two weeks ago became the first French woman ever to perform an extravehicular activity (EVA). It will be the seventh for Meir, which will put her third among female NASA astronauts behind Peggy Whitson (10 EVAs) and Suni Williams (nine).

There have been just five all-female ISS spacewalks to date, and Meir has been part of three of them — the first three, in fact. She conducted those with fellow NASA astronaut (and Artemis II crewmember) Christina Koch on Oct. 18, 2019, Jan. 15, 2020 and Jan. 20, 2020.

NASA's Neil Gehrels Swift Observatory is back to studying the universe after spending months in a low-drag configuration while awaiting an orbital rescue mission that ultimately fell short.

Mission controllers restarted two of Swift's three science instruments — its X-ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT) — on Aug. 26. Both instruments had been shut down in February as part of an effort to minimize atmospheric drag and keep the aging spacecraft in orbit long enough for another spacecraft to reach and boost it to a higher altitude, according to an Aug. 28 statement from NASA.

Swift's third instrument, the Burst Alert Telescope (BAT), remains offline. Operations of the BAT were halted in April to conserve power, allowing controllers to position Swift's solar panels in a way that further reduced drag from its interaction with Earth's atmosphere. NASA says the mission team hopes to resume data collection with the instrument within the next few weeks.

"Over the last 21 years, Swift has been NASA's multitool for studying the cosmos," NASA officials said in the statement. "It observes a wide range of light, rapidly points at short-lived outbursts, and sends alerts to other facilities in space and on the ground to help coordinate follow-up observations."

The return to science follows NASA's decision to abandon plans to boost Swift's orbit using LINK, a robotic servicing spacecraft built by the Arizona company Katalyst Space. LINK launched July 3 aboard a Northrop Grumman Pegasus XL rocket with the ambitious goal of rendezvousing with Swift, grabbing the observatory and raising its orbit.

However, the rescue mission encountered trouble in late July when LINK developed attitude-control problems that caused it to spin and disrupted communications. Two of the spacecraft's three reaction wheels were found to be inoperable, while its cold-gas thruster system also experienced some loss of functionality.

Although engineers managed to reduce LINK's spin and regain attitude control, NASA and Katalyst announced Aug. 19 that the spacecraft would no longer attempt to capture and boost Swift. Instead, LINK is expected to rendezvous with Swift and perform proximity operations, providing an opportunity to demonstrate technologies that could be used for future in-space satellite servicing missions — leaving Swift without the orbital boost intended to extend its life and its future increasingly uncertain.

Launched in 2004, Swift was originally designed for a two-year mission studying gamma-ray bursts, the most powerful explosions in the universe. More than two decades later, the observatory continues to detect and rapidly follow up on fleeting cosmic events in gamma-ray, X-ray, ultraviolet and visible light, while alerting other observatories so they can turn their attention to the same targets.

Unlike some spacecraft in low Earth orbit, Swift doesn't have a propulsion system capable of counteracting atmospheric drag. Increased solar activity has heated and expanded Earth's upper atmosphere, increasing the drag on Swift and causing its orbit to decay faster than previously expected.

NASA's low-drag operations had been expected to keep Swift above an altitude of about 185 miles (300 kilometers) until October. Below that threshold, operating the observatory becomes increasingly difficult and its descent accelerates, NASA officials said in the statement.

Now that science operations have resumed — and the planned orbital boost is off the table — NASA expects Swift to reach that critical altitude within the next one to two months. Without intervention, the observatory is likely to crash back to Earth later this year, mostly burning up as it reenters the atmosphere, according to the space agency.

For now, the veteran space telescope is making the most of the time it has left — and once again scanning the universe.

One of NASA's intrepid Mars rovers has notched another impressive milestone during its exploration of the Red Planet.

What is it?

NASA's Curiosity Mars rover used its Mastcam camera to capture a panorama made up of 323 individual images. The images were taken on Aug. 1 and Aug. 2, 2026, the 4,972nd and 4,973rd Martian days (or sols) of the rover's mission, just as Curiosity notched a total of 1 kilometer (0.6 miles) of elevation gain throughout its now 14-year exploration of the Red Planet.

The images show the wide expanse of a broad valley nicknamed "Valle Grande," a depression on the side of Mars' Mount Sharp, the 3-mile-tall (5-kilometer) mountain the rover has been climbing since 2014. The valley's floor and northern rim can be seen in the distance.

Why is it incredible?

Curiosity's mission has been incredible for a number of reasons. For one, the daring "sky crane" maneuver that NASA and the Jet Propulsion Laboratory used to land the SUV-sized robot on the Red Planet changed Mars landings forever.

Since then, Curiosity has discovered clues that liquid water once flowed across the surface of Mars and has found tantalizing evidence of complex organic molecules on the Red Planet, including some that scientists consider to be the "building blocks" of life.

And even after 14 years of traveling across the Red Planet and suffering considerable damage to its wheels, NASA says Curiosity has plenty of exploration and science left to conduct.

Another one of NASA's Mars rovers, Perseverance, recently notched a travel milestone of its own when it surpassed 26.2 miles (42.2 km) of travel  — the length of a marathon  — across the Martian surface.

Four astronauts just received the United States' highest space honor.

President Donald Trump gave the astronauts of NASA's Artemis II moon mission the Congressional Space Medal of Honor today (Aug. 28) during a ceremony at Johnson Space Center in Houston.

"This is a very rare thing. It's for courageous people, brilliant people, bestowed on astronauts who have distinguished themselves with exceptional service to the nation and all of mankind," Trump said during the event.

Artemis II launched on April 1 and came back to Earth nine days later. It was the first crewed mission of NASA's Artemis program, which aims to establish a long-term base near the moon's south pole in the coming years.

The flight sent four people — NASA's Reid Wiseman, Victor Glover and Christina Koch, as well as Canadian Space Agency astronaut Jeremy Hansen — on a looping journey around the lunar far side. It was the first crewed trip beyond low Earth orbit since Apollo 17 in 1972, and its astronauts got farther from their home planet than any people ever had before.

Artemis II engaged folks around the world thanks to its importance, its historic nature and the charisma of its astronauts. And some fortuitous orbital dynamics didn't hurt, either: The Artemis II crew were lucky enough to observe a total solar eclipse from beyond the moon, something human eyes had never seen firsthand before.

The Congressional Space Medal of Honor is awarded "to any astronaut who in the performance of his duties has distinguished himself by exceptionalIy meritorious efforts and contributions to the welfare of the Nation and of mankind," NASA wrote in a description of the award, citing Congress' stated criteria.

Though the president gives out the medal, he does so on the recommendation of the NASA administrator, the agency added. Before today, just 30 people had received the award, and most of them are pretty big names. Past honorees include Apollo 11 astronaut Neil Armstrong; Alan Shepard and John Glenn, who were the first Americans to reach space and orbit Earth, respectively; Gemini astronaut Ed White, the first American to perform a spacewalk; and Apollo 13 commander Jim Lovell.

The award was also given to each of the 14 astronauts who died in the space shuttle Challenger and Columbia disasters.

Hansen therefore wasn't the first non-American to receive the medal. Ilan Ramon, one of the seven people who perished when Columbia broke apart upon reentry to Earth's atmosphere on Feb. 1, 2003, was from Israel.

During his speech at today's ceremony, Trump said that the United States is entering a golden age of spaceflight and exploration. And he thanked the Artemis II astronauts for being a guiding light.

"Thanks to the crew of Artemis II, those dreams are closer than ever before," the president said. "We're on the cusp of an adventure and something that's so special, people have really not imagined anything. It's really, civilization is into the stars. The stars are up there and they're beautiful, and you're right next to them. You have the courage to be right next to them. Few people do, but you're leading the way. It's great, great bravery."

The astronauts reciprocated the warmth. For example, they gave the president a blue flight jacket commemorating the mission. And Wiseman, Artemis II's commander, thanked Trump for calling the crew during their mission.

"The one thing that really sticks out to us is, you said how proud you are and how proud our nation is of the job that we have just accomplished," Wiseman said during the ceremony. "And for us, that is what we set out to do. We wanted to inspire this nation and inspire the world, and for us, that showed us we were on the right track. So, thank you for that call."

A private spacecraft failed to rescue NASA's Swift space telescope, meaning the big observatory will come crashing back to Earth in the near future.

The Neil Gehrels Swift Observatory launched to Earth orbit in November 2004. Over the past two decades, it studied gamma-ray bursts — the most powerful explosions in the universe — and other cosmic objects and events using a trio of telescopes.

But Swift's science work is now done, and its days in orbit are numbered.

Call to action

In September 2025, NASA put out a call to action to save Swift, whose orbit was decaying quickly due to high solar activity. The bottom line: The observatory needed a boost to a higher orbit soon, or it would be dragged down to its death in Earth's atmosphere.

The Arizona-based company Katalyst Space Technologies answered that call, and won a $30 million NASA contract to perform the re-boost. In hurry-and-scurry mode, Katalyst built a robotic spacecraft called LINK, which launched on July 3 to meet up with Swift and haul it to a higher orbit.

But LINK suffered attitude-control issues after launch, causing NASA and Katalyst to wave off the rescue attempt.

Timeline troubles

Ghonhee Lee is the CEO of Katalyst Space Technologies.

Speaking to CNN News Central on Aug. 24, Lee said: "You know, this is not the outcome that we wanted, but I think it's very important to recognize the unprecedented scale. This was an ambitious, high-risk, high-reward mission where we designed, built and launched a space robot within nine months."

Lee said that the timeline worked against the group. "I think if we had had 12 months even — just three more months — it would have made a tremendous difference," he told CNN's Kate Bolduan.

Swift is now coming back down to Earth, but it's unclear when and where.

Uncontrolled reentry

"Yes, Swift will have an uncontrolled reentry," said Alise Fisher, public affairs specialist in astrophysics within the Office of Communications at NASA Headquarters in Washington, D.C.

The spacecraft's specific timing for reentry will depend on a number of factors, Fisher told Space.com. "Swift is not likely to reenter sooner than October. NASA will share more information as reentry approaches, following established interagency procedures for such notifications."

NASA expects most of the Swift spacecraft to burn up as it travels through the atmosphere, Fisher said, "but some components are expected to survive reentry. The risk of harm coming to anyone on Earth is unlikely."

Survivability analysis

Swift's dry mass is 613 kilograms (1,351 pounds). The spacecraft's science gear includes a Burst Alert Telescope, an Ultraviolet/Optical Telescope and an X-Ray Telescope.

So what might make it to Earth during Swift's speedy fall through the atmosphere?

The observatory's "dry mass and instruments are such that it will likely disintegrate sufficiently upon reentry to not pose a ground casualty hazard," said Darren McKnight, a senior technical fellow at LeoLabs, a company that keeps a persistent eye on what's going on in Earth orbit.

"However, it has both an X-ray telescope and optical telescope, so the internal workings of those devices might survive," McKnight told Space.com. He said that optical lenses, along with titanium tanks, are components that might make it to the ground.

"I am sure that they have done the analysis but have seen no public reporting on the survivability analysis," he said.

A sign of things to come?

Swift is unlikely to burn up entirely upon reentry, given its mass, said Ewan Wright, a Ph.D. student in interdisciplinary studies at the University of British Columbia in Vancouver and a junior fellow at the university's Outer Space Institute.

We also don't know where it will come down, he noted.

"It has an orbital inclination of 21 degrees, so could reenter anywhere in any latitude from 21 North to 21 South," Wright told Space.com. "The most likely outcome is that any surviving debris will land in the sea, but there is a chance it could impact a built-up area and cause a casualty."

Even if Swift's return to Earth is uneventful, "there are more and more uncontrolled reentries of satellites and rockets each year, and the chance that someone will be hit is growing," Wright said.

"Houston, we have a working comm link again."

Thanks to the efforts of two astronauts, such a call is possible again using one of two Space-to-Ground antennas outside the International Space Station (ISS). The pair finished the replacement of a faulty dish assembly during a spacewalk on Tuesday (Aug. 25).

Anil Menon of NASA and Sophie Adenot of the European Space Agency (ESA), who previously removed a faulty dish during a spacewalk on Aug. 18, installed a spare in its place and moved the broken assembly from a temporary to more permanent storage location along the station's backbone truss.

With Menon positioned at the end of the Canadarm2 robotic arm and Adenot traversing by handrails to join him, the two Expedition 75 crewmates first retrieved a spare Space-to-Ground Antenna (SGANT) from an external stowage position. Menon and the spare dish were then maneuvered to the Z-1 truss, where it was mounted and connected to the station's power and data systems.

Menon and Adenot then retrieved the faulty antenna, which they had stowed on the Z-1 truss during the prior spacewalk. Menon (on the arm) moved it to external stowage platform-3 (ESP-3) on the starboard side of the truss.

The replacement work became necessary after the SGANT ceased being able to track NASA's data and relay satellites, rendering it unusable, beginning last November. A second antenna has been in use since, continuing the transmission of voice and critical data, but this repair re-established redundancy to the system.

"On behalf of CAPCOM and I, we're going to count down like a bolt: '3, 2, 1… You just saved the video dish, you just saved the video dish,'" sang astronaut Anne McClain from Mission Control at NASA's Johnson Space Center in Houston, parodying the The Buggles' 1979 hit "Video Killed the Radio Star."

"Oh my god, it is hard to top that," replied Menon, who could be heard laughing along with Adenot. "I want to thank the entire team on executing this complex, time-critical operation successfully."

Tuesday's spacewalk began at 8:27 a.m. EDT (1227 GMT) and was completed exactly 6.5 hours later, at 2:57 p.m. EDT (1857 GMT).

The extravehicular activity (EVA) was the 283rd in support of ISS assembly, maintenance and upgrades. It was Menon's third EVA, increasing his total spacewalking time to 19 hours and 20 minutes. It was the second time that Adenot worked in the vacuum of space, raising her time on EVA to 12 hours and 53 minutes after becoming the first woman and fifth citizen of France to perform a spacewalk.

This was the sixth outing from the International Space Station this year, the third EVA for Expedition 75 and the 98th spacewalk using U.S. extravehicular mobility unit (EMU) spacesuits at the station.

Two astronauts will do some repair work outside the International Space Station today (Aug. 25), and you can watch the action live.

NASA's Anil Menon and Sophie Adenot of the European Space Agency will conduct a spacewalk today (Aug. 25) to replace a space-to-ground-antenna. The extravehicular activity (EVA) is expected to start around 8:35 a.m. EDT (1235 GMT) and last 6.5 hours.

You can watch it live here at Space.com, courtesy of NASA, or directly via the space agency. Coverage will start at 7:00 a.m. EDT (1100 GMT).

This will be the third spacewalk for Menon and the second for Adenot, the first French woman ever to conduct an EVA. Her history-making first excursion occurred on Aug. 18, when she and Menon removed a failed space-to-ground antenna, a relay link that enables high-speed communications between the International Space Station (ISS) and Mission Control at Johnson Space Center in Houston.

The duo ran out of time before they could install a replacement antenna, however. They'll finish the job today, if all goes to plan.

"If time allows, Menon and Adenot also will attempt a get‑ahead task to replace a retroreflector on the forward port of the space station's Harmony module, which will improve navigation data for visiting spacecraft," NASA officials wrote in a spacewalk preview.

Adenot arrived at the ISS in February as part of SpaceX's Crew-12 mission, which also includes NASA astronauts Jack Hathaway and Jessica Meir and cosmonaut Andrey Fedyaev.

Menon came aboard on July 14, making the trip on a Russian Soyuz spacecraft along with cosmonauts Pyotr Dubrov and Anna Kikina. Menon performed his first-ever spacewalk on Aug. 6, with Meir.

Menon will be "crewmember 1" on today's spacewalk, and Adenot will be "crewmember 2." The EVA will be the 283rd in the history of the ISS, which has been continuously occupied by rotating astronaut crews since November 2000.

HOUSTON — What does NASA's astronaut training hub look like these days, as the agency aims to bring more commercial space stations into the fold?

It's an interesting mix of government and private companies, of space agency personnel and of contractors, all working together to keep U.S. and international astronauts flying through the end of the ISS — currently expected around 2030 — and the new breed of commercial space stations expected to take its place.

Canadian reporters like myself were invited on a tour of Johnson Space Center (JSC) on Aug. 4 ahead of the launch of SpaceX Crew-13, which launches no earlier than Sept. 12. Canadian Space Agency astronaut Josh Kutryk is a mission specialist on the Crew Dragon spacecraft, which also includes NASA commander Jessica Watkins, NASA pilot Luke Delaney and Roscosmos mission specialist Teteryatnikov.

The ISS remains an active program for at least a few years; NASA managers reiterated in a press conference here on Aug. 3 that they are still targeting an end-of-operations in about 2030 — but they are prepared to extend the lifetime of the station if directed by Congress (which wants to keep going at least another two years).

The space station has had a leak on the Russian side for several years, and astronauts recently and briefly sheltered in a Crew Dragon during discussions of a fix. At the press conference, NASA added the situation is under control as Roscosmos agreed to essentially seal off that area. Major station systems, they added, are otherwise in good health.

But as spaceflight takes planning, teams are already thinking about "lessons learned" when the ISS retires for a new generation of mission planners, which would include an even greater focus on companies. NASA's Commercial LEO (Low Earth Orbit) Destinations or CLD program aims to have private space stations for astronauts by the time the ISS retires, and handed out early-stage contracts valued at about $415 million in 2021 to three teams led by Nanoracks, Blue Origin and Northrop Grumman. After NASA briefly considered changing the program's scope, after input from industry a new request for proposals advancing CLD should be out soon.

Meanwhile, companies like Vast Space have their own self-funded modules almost ready to fly, while Bigelow Aerospace has an inflatable module on ISS that is being tested, long-duration wise, to make sure the concept holds up for a future free-flying destination. No matter who hosts astronauts, however, NASA officials on the tour said they are prepared to offer expertise and help — and there is no other visible demonstration of that expertise to the public than the ISS Mission Control, which is often shown live on NASA+ during a selection of space station operations.

Mission Control: 'We have all of those disciplines'

The Mission Control building holds several dedicated control rooms for different mission purposes, including an historic Apollo control center and another room alternately used for Boeing Starliner and Artemis missions. I've been lucky enough to visit all of these in the past. Our only stop in the building Aug. 4, however, was the iconic ISS mission control.

On screen at the front of the room, the Expedition 75 astronauts were awake and active, occasionally zooming by a camera mounted inside the Destiny U.S. lab sandwiched between two station "nodes" leading to other modules. Flight director Diane Dailey told us the controllers are watching for things like if the astronauts are loaded down with equipment, which indicates that would not be a good time to call unless urgent. "We usually have that live camera view just up for awareness. It just helps us understand," she said.

Speaking of calls, an open laptop screen, deliberately positioned within view of the camera, showed all "green" on the comms channels—which helps ground controllers figure out if the crew can hear them, as the station flies in and out of satellite and ground station views all the time. (A flight map, also at the front of the room, also allows for tracking the station and its communications capabilities as it flies around the world.)

While it was hard not to keep gazing at these screens, what was almost as mesmerizing was watching the quiet group of ISS controllers positioned in front of their own laptops and occasionally holding side conversations about their systems. SpaceX now has its own Mission Control in California for its spacecraft, while Boeing chose to integrate theirs with NASA's. Whatever pathway companies choose, however, Mission Control will remain an important example of "division of labor" for future space stations.

"You're going to see different consoles that specialize in different aspects of spacecraft operations," Dailey said. "I like to kind of think of it in terms of, 'What are all the capabilities you'd need on any given spacecraft', right? You'd need propulsion. You'd need communications. You'd need computers. All of those things. So, we have all of those disciplines and all those areas in the spacecraft represented here."

Building 9: What to do 'when you no longer have gravity assisting you'

The Space Vehicle Mockup Facility — known to JSC workers as Building 9 — is constantly in flux, because modules constantly shift in and out of the facility for different missions. The facility's goal these days is not only to support NASA missions, but also private industry, by providing the physical space and hardware to simulate problems in space if they arise.

When it comes to astronaut training, one example is learning how to do CPR: "CPR is hard enough when you have gravity. When you no longer have gravity assisting you, they [astronauts] have to learn to 'strap in'," said Mathieu Caron, the CSA's director of astronauts, life sciences and space medicine, who accompanied reporters on the tour of Building 9.

That's only one example of an emergency, of course. Another one is fire alarms—in which the astronauts learn how to quickly gather their team in a "safe haven" with communications and computers available to talk with Earth, then to make sure everyone is there before assessing the situation and figuring out how to deal with it (which could mean fighting the fire, or heading to an escape vehicle.)

When astronauts are training for fire alarms in Building 9, Caron said, there's an extra step involved: letting nearby personnel know that the simulated fire alarm in the ISS area is not the actual fire alarm for the building. "Like, if you hear this specific bell, it's because they're just practicing that training," he explained.

The emphasis of our visit was on ISS operations, given that we were visiting in association with Crew-13, but the facility's website also mentions "commercial space flight companies and exploration programs" among the customers.

While walking the perimeter of the building alongside NASA and CSA, we could see some distant glimpses of other companies' hardware — from SpaceX and Blue Origin, for example, as well as the Starlab Space consortium's multi-floor space station mockup. As NASA very much intends to be the customer on future CLD destinations, surely more of these companies will be occupying the floor of Building 9 after the ISS retires.

Neutral Buoyancy Laboratory: 'The better they get, the more we treat it like the real world'

Our last stop on the Gilligan-like three-hour tour was the Neutral Buoyancy Laboratory, which is part of JSC's Sonny Carter Training Facility and about a 15-minute drive from the heart of the NASA campus. Most space people would easily recognize this place as the spot where astronauts rehearse spacewalks, clad in adapted spacesuits simulating what they'll feel for real the moment they step out the hatch.

I spent much of my childhood in community center pools, learning how to swim, and when I walked beside the football-field-sized pool for the first time the humidity — and the echoes on the ceiling and walls from noises — felt somewhat like old times. The scale, however, was strange. The echoes were happening much further away from me, while the humidity was less intense given the expanse of the huge facility. It was hard for my mind to settle, as the setting felt both familiar and unfamiliar.

We only spent a few moments poolside, however, as getting up on the catwalks allowed a much better view of the scene. In one zone were the ISS module mockups inside the pool, through which a couple of astronauts were training while surrounded by divers. (You could track the team's progress by watching the bubbles and hoses on the surface.)

"When they [astronaut candidates] first start, we help them a lot," the NBL's Tim Hall told our media group. "The more mature they get in their training, and the better they get, the more we treat it like the real world — and let them execute on their own."

In another was an area where the Orion spacecraft for the Artemis 2 moon mission was put through its paces during training: Could the arriving divers handle waves? What if the spacecraft landed upside-down? All of these things were simulated repeatedly to ease recovery operations.

"Have you ever watched 'Apollo 13'?" Hall asked us. (It's the movie that sparked my interest in space when I saw it on VHS in 1996, so yes.) "If you're a fan, at the end of the movie, you'll see them at 'Stable 1'," he continued — that means the spacecraft is upright in the water.

"We have Stable 1, 2, 3, 4. Those are all the positions of the vehicle when it's laying in the water. So, this thing is actually training for the crew. … we can rotate [the spacecraft], so they train the crew how to get in and out of it in the different stable conditions."

The deep-ocean capabilities are not only useful for spacecraft, but for applications like the oil industry: the pool has been used in past years to simulate offshore work and fire training for the engineers on distant rigs, for example. Private space companies also have had their own time in the pool for spacesuit applications, such as what Axiom Space advertised in 2025 to test the Axiom Extravehicular Mobility Unit (AxEMU) spacesuit that NASA astronauts are expected to use on the lunar surface.

Could more companies come in as the ISS program winds down? Hall says right now a lot of the spare capacity is taken up by the U.S. Navy, but the NBL does expect to offer more of these commercial services in future — as it's already advertised on their website.

"We're open to that for sure," Hall said. "We haven't had anybody out here yet for, like, a recovery or anything on training like that from a private space [company], but that's definitely something we'll address."

NASA's Artemis II moon astronauts will join a very exclusive club next week.

President Donald Trump will award those spaceflyers the Congressional Space Medal of Honor next Friday (Aug. 28) at Johnson Space Center in Houston to recognize their historic journey around the moon this past April.

The ceremony will begin at 11 a.m. EDT (1500 GMT) and will feature NASA Administrator Jared Isaacman, President Trump and the Artemis II astronauts. You'll be able to watch it live when the time comes.

Artemis II sent NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, as well as the Canadian Space Agency's Jeremy Hansen, on a 10-day trip around Earth's nearest neighbor. It was the first crewed voyage beyond low Earth orbit since 1972, when the Apollo 17 astronauts returned home from the moon.

The mission's success was a huge step for NASA's Artemis program, which aims to establish a base near the lunar south pole in the coming years.

The Congressional Space Medal of Honor is the highest award that the U.S. government can bestow upon an astronaut. It's possible that only Wiseman, Glover and Koch will receive it next week; NASA's media advisory about the event states that Trump will give the medal to "each of NASA's Artemis II crew members," suggesting that Hansen might not be included. (The award is not limited to American citizens.)

Thirty people have received the Congressional Space Medal of Honor to date. They are:

• Neil A. Armstrong
• Frank Borman

On Aug. 20, 1977, NASA launched the Voyager 2 spacecraft on a mission to explore the outer planets. Despite its name, this was the first of the two Voyager missions NASA launched that year.

Voyager 2: Sailing Among Giant Planets

Thanks to a rare alignment of the planets, NASA had the opportunity to send a spacecraft on an unprecedented journey to Jupiter, Saturn, Uranus and Neptune.While Voyager 1 ended its planetary mission after Saturn, Voyager 2 completed a 12-year journey to Neptune. But they didn't stop there!

Voyager 1 left the solar system and entered interstellar space in 2012, and Voyager 2 followed suit in 2018. As it approaches 50 years of operation, the probe continues to return data from three functioning science instruments.

Why it mattered

Nearly half a century later, it remains the only spacecraft to visit all four has giants in our solar system, and the only spacecraft humanity has ever sent past Uranus and Neptune. Some of Voyager 2’s biggest surprises came from the moons orbiting those planets. Its images of Neptune’s largest moon, Triton, revealed active geyser-like plumes blasting nitrogen miles above the surface — making it one of only three geologically active moons in the solar system (maybe four, depending on what Europa Clipper finds).

Decades beyond its original mission, Voyager 2 has begun studying the Kuiper Belt environment beyond the Sun’s protective heliosphere, giving scientists measurements from a region no spacecraft had been designed to reach. Voyager 2's plutonium power supply drops in efficiency about four watts per year, and NASA engineers were recently able to reduce how much power Voyager 2 needs by switching off a number of non-science components to adapt a less demanding method of warming the spacecraft while it continues traveling ever farther away from the sun.

NASA is calling off the effort to save its Neil Gehrels Swift Observatory after a private rescue spacecraft couldn't overcome its own problems in orbit.

LINK, the specialized probe from Katalyst Space that NASA contracted for the Swift Boost mission, was delivered to space on an air-launched Northrop Grumman Pegasus XL rocket on July 3. The vehicle was designed to rendezvous with the Swift Observatory in order to grapple and raise it to a more stable orbit, but LINK ran into trouble when it began to spin uncontrollably about three weeks after launch.

Today (Aug. 19), NASA announced an official end to LINK's efforts to boost Swift's orbit, citing ongoing attitude control issues with the private spacecraft, but the agency hasn't canceled the mission outright. LINK will still attempt a rendezvous with Swift in order to practice proximity operations and demonstrate its capabilities other than spacecraft capture, which could aid future missions down the road.

From its inception, the Swift Boost mission was always viewed as a long shot. Increased solar activity had already begun decaying the observatory's orbit faster than anticipated when NASA awarded the $30 million Swift Boost contract to Katalyst in 2025, giving the Arizona-based company less than a year to complete LINK's design, manufacture and testing before time to save Swift would run out.

"NASA should be willing to move quickly and take smart risks when the potential return is worth it, and that is exactly what we did with this mission," NASA Administrator Jared Isaacman said in a statement today. "This is not the outcome we were working toward, but it does not change why this mission was worth attempting. The team moved with extraordinary speed to give Swift a chance to carry out more science while advancing capabilities America will need for satellite servicing in the future."

Swift is a one-of-its kind orbital observatory designed to study high-energy phenomena across the universe. It can detect sudden events like gamma-ray bursts and quickly direct its instruments to study them in X-ray, ultraviolet and visible light. The spacecraft is also routinely redirected for rapid response research to study things like newly discovered supernovae, black-hole ejections, fast radio bursts and other short-lived astronomical events.

With LINK now incapable of boosting Swift's orbit, NASA estimates the observatory will dip catastrophically low into Earth's atmosphere before the end of the year. After Swift dies, the agency says it will "continue to prioritize finding new options to react rapidly to cosmic events, using current missions to help fill the gap in the meantime."

Katalyst is working closely with NASA as the Swift Boost mission enters its next phase. Together, the company and space agency are evaluating logistics for LINK's rendezvous and maneuvering demonstration within Swift's vicinity, which will provide data for potential future servicing missions to other satellites, NASA's statement says.

Two astronauts — including the first French woman in history to perform a spacewalk — worked outside of the International Space Station (ISS) on Tuesday (Aug 18), becoming temporary TV repairpersons. Just like what frequently happens on Earth, the work required more time than the "appointment" allowed, requiring a second visit to be scheduled.

NASA astronaut Anil Menon and ESA (European Space Agency) astronaut Sophie Adenot were tasked with the removal and replacement of a Space-to-Ground antenna that since November had ceased being able to track NASA's data relay satellites, rendering it unusable. A second antenna has been in use since, continuing the transmission of critical data and enabling high-speed communications with Mission Control Houston.

Spacewalk planners had allocated about six and a half hours for the work to be completed. The two Expedition 75 crewmates were successful in removing the failed Space-to-Ground antenna from its mount on the station's truss but ran into delays disconnecting its electrical connections and and locking down gimbal bolts, or pins, to secure the large dish assembly during its transport to its temporary stowage location.

"We got into this with the mindset that we wanted everything to go perfectly," said Menon as the spacewalk came to an end. "Things were a lot different than expected, but what I would say that I am really impressed with is that all of those contingencies were well thought out."

As such, flight controllers had the astronauts tether the failed antenna to the truss and waived them off installing the replacement antenna, leaving it for a future extravehicular activity (EVA) still to be scheduled. Mission managers will decide whether to add that task to a spacewalk already planned for next Tuesday (Aug. 25) or to leave it for a later outing.

"We are looking at times," radioed Mission Control to the spacewalkers. "We are going to go directly to the long-duration tie-down of this SGANT on the Z-1 truss."

Menon and Adenot began the spacewalk at 8:29 a.m. EDT (1229 GMT) when they switched their spacesuits to battery power. Their EVA ended once they were back inside the U.S. Quest airlock and re-pressurization began at 2:52 p.m. EDT (1852 GMT).

Their total time logged on this spacewalk was 6 hours and 23 minutes.

Tuesday's spacewalk was the 282nd in support of ISS assembly, maintenance and upgrades. It was Menon's second EVA since making his first outing with fellow NASA astronaut Jessica Meir on Aug. 6, increasing his total spacewalking time to 12 hours and 50 minutes.

It was the first time that Sophie Adenot ventured into the vacuum of space, making her the first female and fifth citizen of France to perform a spacewalk after Jean-Loup Chrétien, Jean-Pierre Haigneré, Philippe Perrin, and Thomas Pesquet.

"What a day!" said Adenot. "My deepest gratitude to everyone who made this possible — the pioneers who came before us, but also the incredible teams working behind the scenes today."

This was the fifth spacewalk conducted out of the International Space Station this year, the second for Expedition 75 and the 97th using U.S. extravehicular mobility unit (EMU) spacesuits at the space station.

Sophie Adenot will make spaceflight history today (Aug. 18).

The European Space Agency (ESA) astronaut will become the first French woman ever to conduct a spacewalk, an activity she'll undertake with NASA astronaut Anil Menon.

The duo are scheduled to step outside the International Space Station (ISS) for a 6.5-hour excursion today at around 8:35 a.m. EDT (1235 GMT). You can watch it live here at Space.com, courtesy of NASA. Coverage starts at 7 a.m. EDT (1100 GMT).

Adenot and Menon will "replace a space-to-ground antenna on the orbital complex," NASA officials wrote in a spacewalk preview.

"The antenna is a critical communications link NASA uses to transmit data, enabling high-speed communications between the Mission Control Center in Houston and the space station," they added.

This will be the second spacewalk for Menon; his first one, conducted with fellow NASA astronaut Jessica Meir, occurred on Aug. 6. During that extravehicular activity (EVA), a carbon dioxide sensor on Menon's spacesuit gave "an unexpected data reading," NASA officials wrote in an Aug. 7 update.

The sensor returned to normal after Menon doffed the suit, but NASA took some extra time to make sure there was no serious issue. As a result, the agency pushed his second spacewalk back a few days — from the originally planned Aug. 13 to today.

Today's spacewalk will be the 282nd overall in the long history of the ISS. Menon, who reached orbit on a Russian Soyuz spacecraft on July 14, will be "crewmember 1" on the EVA. Adenot — a member of SpaceX's Crew-12 mission, which reached the orbiting lab in February — will be "crewmember 2."

Adenot won't be the first French person overall to conduct an EVA. That distinction goes to Jean-Loup Chrétien, who performed a spacewalk outside the then-Soviet Union's Mir space station in 1988.

Other male French astronauts, including Philippe Perrin and Thomas Pesquet, later spacewalked outside the ISS. Pesquet also became the first French person to command an ISS mission, taking the reins in October 2021.

MORRISON, Colorado - The Artemis II crew that circuited the moon earlier this year came full circle, dropping by a distinctive spot on Earth that's visually reminiscent of both the moon and Mars.

On Aug. 3, the vast and stunning Red Rocks Amphitheatre served as both an inoculation of near-term nostalgia and heart-felt congratulations to the crew for the impressive journey of Artemis II. The 10-day mission began on April 1 of this year, flew around the moon and back, and splashed down in the Pacific Ocean on April 10. It was the first crewed flight to saunter spaceward beyond low Earth orbit in 53 years.

Some 8,500 people packed the open-air venue at Red Rocks to make eye-contact with space travelers Reid Wiseman, commander, Victor Glover, pilot, Christina Koch and Jeremy Hansen as mission specialists – all of them clearly awestruck by the crowd reaction. The event was a broader post-flight campaign for the foursome, also spotlighting the region's contributions to the sojourn of Artemis II. A science, technology, engineering, and mathematics (STEM) fest was also part of the early morning affair.

Iconic location

"I can't imagine a more iconic location on Earth to hear about the trip to the moon," said Robert Lightfoot, president of Lockheed Martin Space and a major aerospace contractor for the Artemis program. There were hundreds of suppliers across the rocky mountain region, over 10,000 employees, that supported the Artemis II mission, he told the gathered throng.

Leadership from industry prime contractors including Lockheed Martin, Amentum, Boeing, L3 Harris and Northrop Grumman took part in the salute to the Artemis II voyage.

Colorado Governor Jared Polis pointed out that "here in Colorado, we're a mile closer to space." As the best and biggest homecoming for the Artemis II crew, he added, "keep reaching for the stars."

Lori Glaze, NASA associate administrator for the Human Spaceflight Mission Directorate, said today "is a truly revolutionary and exciting time for NASA and America's space program. We are going to reach farther. We're going to dream bigger. And we're going to secure America's leadership in deep space exploration and discovery."

What next?

In a pre-event press gaggle, Space.com asked the Artemis II crew members how their Orion spacecraft named Integrity performed and would help the upcoming Artemis III crewed flight in Earth orbit.

"It handled incredibly well," said Reid Wiseman, Artemis II commander. "Just from habitability, I think that is where we learned the most, putting four humans in the spacecraft. We knew that the machine was technically competent and capable of getting to the moon … Artemis I taught us that," he told Space.com.

"We had some heat shield things we needed to sort out on Artemis II. But putting the four of us in there, seeing how the life support system worked and how is it for habitability, to eat, live, work, and sleep in there, we definitely learned a lot that we've handed on to Artemis III," said Wiseman.

Sense of gratitude

The Red Rock Artemis II stage event had the four Artemis II crew members facing a huge gathering of supportive spectators. In excess of 1,300 questions were submitted by the attendees.

The Artemis II crew entrance was marked by roaring footage of the Artemis I launch scored by music from thunderous Metallica's "Fuel."

"The biggest thing that this mission has given us is an overwhelming sense of gratitude. I think we've got to figure out how to keep this going," Glover said.

For Christina Koch, the Red Rocks gathering spurred a call and response audience participation. "I say moon, you say joy," to which the throng promptly called back three times. She also asked the audience to put their thumb out in the air. From a distance, "you can cover the entire Earth with your thumb. That's how small it was to us," she said, "but what you knew was that was home."

Proximity operations

Victor Glover, the pilot of Artemis II, focused on a proximity operations demonstration during the flight. That entailed the crew guiding the spacecraft through a series of controlled approach and retreat maneuvers using the detached upper stage, the interim cryogenic propulsion stage, as a reference target.

"That is when we had a chance to fly the spacecraft by hand, not just using the computers," Glover told Space.com. "We actually got to fly. One of the most amazing aspects of that is looking out the window or through the cameras on the [cockpit] displays to determine how far we were from the upper stage," he explained.

That task made use of all four sets of eyes onboard Orion, Glover said. "We did not have radar, or some other type of digital ranging system between us and that vehicle. But the Artemis II team trusted us to fly like that. I'm still blown away by that trust," he said, "and it flew marvelously."

South pole ambitions

NASA's Glaze added that Artemis III is to fly sometime mid-year in 2027.

"We are going to demonstrate docking with one or both of our two landers, the Blue Origin and the SpaceX lander. They've got some demonstration versions that they are preparing right now. We're working on that mission to prove out, not just going back and forth at a target, but actually docking and doing that hard job," Glaze told Space.com.

Space.com pressed Glaze on the term "demonstration versions" of the Blue Origin and SpaceX lunar landers.

Would the fidelity of those demos be good enough to green-light an actual human moon landing on the Artemis IV mission?

"I do," Glaze responded. "We're working really hard with both of our lander providers on development of the demo pathfinder versions of their landers that we will dock with […] to assure that the docking systems are the same docking system we're going to work with when we are going for the landing mission," she said.

Glaze said that "this is one of the key risks. This allows us to buy down that risk and at least work through that part of the mission. So when we do the landed mission we've got that part out of the way.

"We've got our lessons learned from those docking demonstrations. And then we are really focused on all the risks associated with the landing on the moon … we can really focus our efforts there."

According to Space.com sources, however, there is active discussion of whether the lunar south pole is an advisable location for the first human landing of the Artemis Program. Indeed, Artemis II pilot Glover recently stated that he thinks there's a need to be realistic and progressively work our way to the south pole locale rather than land there first.

"We've had a lot of conversations with both of our lander vendors. The designs they have are for the south pole," responded Glaze. "We're working really closely with them on those designs. And we are very focused on landing at the south pole."

Over the moon

Canada's Artemis II mission specialist, Jeremy Hansen, told the audience that their space trek was a very human experience for the four crew members, "but we came to see and feel you. You shared the moon joy," he said.

Hansen underscored the international character of Artemis II. "It was one of those deliberate contributions to the planet," he said, because billions of us on Earth have to join forces. "We have to work together. We can no longer believe that our end-state is not working together. Not acceptable. We have to collaborate," he said.

Asked by a young audience member about items taken on their excursion around the moon, mission specialist Koch replied: "I took handwritten letters that I hadn't read before from my family, and also a very tall cow figurine. My dad had the idea of having a cow jump over the moon."

Not every canceled NASA program earns a halo after its demise, but one scrapped project is finding new life by contributing its parts to help the space agency achieve its moon base goals faster.

Northrop Grumman is repurposing hardware and technology from the Habitation and Logistics Outpost (HALO) space station module for use on a new series of Lunar Infrastructure Demo (LID) missions. HALO was originally designed as the habitation module for NASA's since-cancelled moon-orbiting Gateway space station but found itself on the chopping block when the agency restructured the Artemis program architecture earlier this year.

Rather than scrap the unfinished module outright, Northrop Grumman will adapt HALO's electrical and mechanical components to support the development of technologies for a moon base that can survive the cold, weeks-long night at the lunar south pole while sustaining the long-term habitation of astronauts inside.

Part of NASA's reasoning for canceling Gateway was the need for expedience. As the agency's vision for Artemis and the return of astronauts to the lunar surface has evolved, China's plans to land the first taikonauts on the moon have steadily taken shape. Those ambitions, and the continued progression of China's lunar program, have kicked off a new space race in which the U.S. and NASA are intent on maintaining their first-place position.

In March, NASA Administrator Jared Isaacman announced a shakeup to the Artemis program designed to enable a more step-by-step approach toward developing the technologies needed for a next-generation crewed lunar landing, and to achieve that landing on the shortest timeline possible.

That timeline currently puts the first Artemis lunar landing with astronauts on the Artemis IV mission, scheduled for late 2028. Before then, however, NASA is planning nearly two dozen uncrewed missions to the moon to lay the groundwork for the infrastructure needed to precede astronauts' return. And, rather than let HALO rust in a warehouse, Northrop is doubling down on its commitment to the cause.

"To help NASA move faster … HALO’s power, data and mechanical interfaces will enable NASA to move with speed and begin gathering real lunar surface performance data sooner," the company said in a press release on Aug. 4.

Northrop announced 3 LID missions to "reuse HALO-derived technologies to rapidly mature lunar surface power, thermal, autonomy, communications and hosted payload services," which will help NASA gather data to better protect robotics and crews during long-duration stints near the moon's south pole, where the agency plans to establish its Artemis moon base. Neither the company nor NASA gave a target timeline for these missions.

NASA is targeting the south pole specifically because of the abundance of water ice that scientists have detected in that region on the moon. When harnessed appropriately, such ice concentrations can be used for a variety of applications to enable sustainable habitation on the lunar surface — the ultimate goal of the Artemis program — including potable water, radiation shielding and rocket fuel.

NASA believes that overcoming the technological hurdle of "in-situ resource utilization" (ISRU), or the ability to rely on materials locally available to you in order to sustain your survival, is the gold standard of spaceflight that will open the door to humanity's long-term exploration of the cosmos. Manufacturing propellants off Earth, for example, would mean a substantial increase in the distance any particular mission to space can fly, because nearly 95% of a rocket's mass at launch is fuel. So, the ability to refuel in space, circumventing the burden of launching to orbit fully fueled, would give satellites and crewed spacecraft the ability to fly much farther into the solar system than current launch systems allow.

As much as Artemis is, in itself, a program to establish a permanent human presence on the moon, NASA also sees it as the proving ground for technologies that could one day sustain astronaut missions to Mars. There is worry, however, over the national security and economic consequences that could accompany China beating the U.S. to the moon, so speed is top of mind for those tasked with the country's lunar return.

"As America embarks on the next chapter in human space exploration, our Lunar Infrastructure Demos will help turn the moon into a place where astronauts can stay, work and make discoveries that benefit humanity,” said David Schiller, Northrop Grumman's vice president of civil space and sciences, in a statement. “Our ready‑to‑fly, reliable HALO technologies allow NASA to move faster, putting in place robust infrastructure that can endure the lunar night and establish a strong blueprint for a future moon base.”

A radiation-shielding vest might one day protect astronauts from dangerous, random outbursts from the sun, a new study finds.

More than 50 years after the final Apollo mission, NASA's Artemis program aims to return humans to the moon. To succeed, this project must protect astronauts from solar radiation, especially the intense and unpredictable radiation from solar storms. Coating an entire spacecraft with a meaningfully thick layer of radiation shielding remains impractical due to weight constraints, but wrapping astronauts in protective garments may potentially be helpful.

In the new study, researchers experimented with the AstroRad vest, which was designed by the Israeli startup StemRad with support from the Israel Space Agency and aerospace giant Lockheed Martin. The garment was created to protect astronauts from explosions from the sun known as solar particle events.

"Radiation in space is unavoidable, and a single major solar particle event can make a substantial contribution to an astronaut's lifetime risk of radiation-induced cancer," study co-author Oren Milstein, CEO and co-founder of StemRad, told Space.com. "By significantly reducing that contribution, personal shielding could be particularly important for future lunar and Mars missions."

When it comes to protection against radiation, lead is excellent at blocking hazardous forms of light, such as X-rays and gamma rays. However, lead is much less effective at defending against the kinds of dangerous particles that can hurtle through space. For instance, when fast high-energy electrons known as beta particles strike dense lead atoms, they can trigger a shower of X-rays that are more harmful than the beta particles themselves. And if neutrons strike lead atoms, they can knock loose a spray of neutrons from the atoms' nuclei, worsening the impact from the radiation.

Instead, AstroRad relies on a high-density plastic rich in hydrogen. Among the elements, hydrogen possesses the highest density of electrons per atom, which can help create a dense shield to protect against incoming particles. At the same time, hydrogen atoms normally do not have neutrons, so if neutrons hit them, they cannot generate the kind of dangerous neutron sprays that can happen with lead atoms.

Moreover, the plastic in AstroRad is much lighter than lead. This makes it easier to move around in garments incorporating the plastic, and more practical for space missions in which weight is a major limitation.

The scientists combined thousands of hexagonal rods of the rigid plastic together like scales to create a flexible garment. All in all, each vest weighed about 57 pounds (26 kilograms).

The scientists developed a vest rather than a full-body suit or a helmet because "different organs and tissues have very different sensitivities to radiation, so shielding every part of the body equally is not the most effective approach," study co-author Jordan Houri, lead scientist for space exploration at StemRad, told Space.com. "At the same time, a full-body suit would be much harder to put on and move around in."

The shielding thickness of the AstroRad vest was based on how sensitive to radiation the underlying organs were. This strategy provides about a 30% greater reduction in the dose of radiation a person receives compared with distributing the same amount of shielding uniformly across the body, Houri said.

The researchers tested their vest during NASA's uncrewed Artemis I moon mission in late 2022 using a pair of extraordinarily complex dummies called phantoms. These artificial torsos were constructed of plastics that mimicked the density of human tissue, bone and organs, and each was equipped with more than 5,600 radiation sensors on and in them.

The two phantoms were designed to be adult females, since previous research found that breasts and ovaries are especially susceptible to radiation damage.

"Women are predicted to face a higher risk of radiation-induced cancer," Milstein said. "Targeted shielding could help narrow that difference in risk between male and female astronauts."

Since the phantoms mimicked women, they were given women's names, Zohar and Helga. "Helga was contributed to the experiment by the German Aerospace Center, and Helga is a traditional German name," Milstein said. "Zohar was contributed by the Israel Space Agency, which selected the name through a public outreach campaign. Zohar is a traditional Hebrew name meaning 'radiance,' which we thought was particularly fitting."

Zohar and Helga flew seated in NASA's Orion spacecraft; Zohar was equipped with an AstroRad vest, while Helga was not. Although Orion did not encounter a significant solar outburst during its 26-day mission to lunar orbit and back, the researchers were able to extrapolate how much solar radiation astronauts might experience based on what the phantoms encountered passing through the inner Van Allen belt of radiation surrounding Earth.

When the scientists analyzed past solar particle events, they found the AstroRad vest would have significantly reduced the dose of radiation a person during those outbursts — for instance, by nearly 60% for a solar particle event that happened in August 1972.

"We had originally anticipated something closer to 45%, so when we first saw the result, we thought we needed to go back and find an error," Houri said. "Instead, the detailed analysis showed that AstroRad's approach of providing targeted shielding to the most radiation-sensitive organs and tissues was even more effective than we had projected."

Such a reduction could spare astronauts the equivalent of up to 193 days of deep-space radiation exposure. "The most important implication is that AstroRad could help overcome one of the major health challenges limiting long-duration human exploration beyond Earth," Milstein said.

AstroRad is not something astronauts would wear continuously throughout an entire mission, Houri said. "AstroRad was developed as an emergency countermeasure for solar particle events, so astronauts would only wear it when radiation levels are elevated, typically for periods of hours or days," he explained.

Still, "although it is not something astronauts would need to wear throughout an entire mission, we designed the vest to remain usable for many hours at a time," Milstein said. During tests with the vests on the International Space Station, "several crew members even slept with it on."

The level of radiation protection the AstroRad vest provided was similar to that supplied by the Orion spacecraft's onboard storm shelter, "while allowing the astronaut wearing it to leave the shelter and continue mission-critical tasks," Houri said. "AstroRad can be used on its own or together with a shelter, but one of its main advantages is that an astronaut can remain protected while moving around the cabin and carrying out essential mission operations rather than remaining inside the shelter."

The scientists are now investigating whether it is possible to manufacture radiation shielding in space using onboard materials. For instance, in collaboration with Florida aerospace company Redwire, "we have already demonstrated that it is possible to 3D-print AstroRad components from recycled polyethylene aboard the International Space Station," Milstein said.

The scientists detailed their findings online today (Aug. 12) in the journal Science Advances.

On Aug. 12, 2005, NASA launched its Mars Reconnaissance Orbiter.

The Mars Reconnaissance Orbiter (MRO) mission lifted off on a United Launch Alliance Atlas V-401 rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station (now known as the Cape Canaveral Space Force Station) in Florida.

Some of the best cameras ever launched into space are on MRO, and the spacecraft has taken some seriously amazing photos of Mars. The High-Resolution Imaging Science Experiment, or HiRISE camera, takes super-sharp photos of the Martian surface and has helped NASA scout the Red Planet for suitable landing sites for rovers like Curiosity. It also serves as a data relay station for other spacecraft on Mars that need to beam data back to Earth.

MRO has also studied water and ice on Mars, and its cameras have revealed some pretty remarkable landscapes.

Why it mattered

Now operational for more than 20 years, MRO serves as one of NASA's oldest spacecraft in operation around the Red Planet. It has become instrumental in the space agency's ability to maintain communication with other probes in orbit around Mars and rovers on the planet's surface.

The probe's HiRISE camera revolutionized scientists' understanding of Mars' diverse surface features, with resolution high enough to picture objects as small as 3 feet (1 meter) wide. Since its arrival in orbit around Mars on March 10, 2006, MRO has snapped more than 100,000 images of the surface below and helped NASA track geologic activity like migrating dunes, impact craters, avalanches, dust storms and seasonal frost changes. And NASA is still finding ways to put the aging satellite's scientific instruments to good use. For example, the agency executed a 120-degree roll program last year designed to strengthen MRO's SHARAD radar signal by 10 times or more, allowing it to probe deeper than 1 mile (1.6 kilometers) underground to detect water ice.

MRO's role as a communications relay for probes on and around Mars became even more important earlier this year, when NASA's MAVEN mission ended in June. Today, MRO returns around 80,000 megabits of data per day, according to Astronomy.com, and remains one of NASA's most critical assets in orbit around Mars.

NASA just made an interstellar tweak to the Voyager 2 spacecraft, known as the "Big Bang", to keep its remaining 50-year-old science instruments running a little longer.

Voyager 2 and its twin launched in 1977, called Voyager 1, rely on a form of nuclear battery known as a radioisotope thermoelectric generator that uses the heat produced by the decay of plutonium. But the supply of plutonium on each probe drops at about four watts a year on each spacecraft.

To keep the probe running on this dwindling power supply, engineers recently reduced Voyager 2's power requirements by turning off a few non-science devices and using "lower-power alternatives" that are still effective enough to keep the spacecraft warm while it's so far from the sun, NASA officials said in a statement. "The spacecraft power margins have grown razor thin, requiring the team to conserve energy by shutting off non-essential devices and systems," NASA officials wrote of the mission, which is managed by the agency's Jet Propulsion Laboratory.

The drop in power is having a measurable science impact on both spacecraft — each has turned off two of their science instruments since 2024 alone. While some of these instruments were shut off after the spacecraft finished their historic planetary flybys decades ago, others were turned off due to power requirements.

Each spacecraft initially launched with 10 instruments, and Voyager 2 is now down to only three instruments. At first it looked as though Voyager 2 would have to shut down another of these instruments later this year, but luckily, the new power shifts will allow all three to operate "for at least another year," NASA said.

Voyager 1 will be tasked to do the same "Big Bang" power change "in the coming months." A signal to each spacecraft takes nearly 24 hours (or one light-day) to make a one-way journey, and officials noted Voyager 1 is further from Earth than its twin. (Voyager 2 is at about 142 astronomical units or sun-Earth distances, while Voyager 1 is nearing 171 AU.)

The two spacecraft initially launched to take advantage of a rare alignment between the outer solar system gas giant planets, which in order of distance from the sun are Jupiter, Saturn, Uranus and Neptune. Each Voyager spacecraft first flew past Jupiter and Saturn, taking unprecedented imagery of the planets and their moons.

Next, Voyager 1 was directed to fly above the plane of the solar system (also known as the ecliptic) while Voyager 2 continued flying past Uranus and Neptune, becoming the first spacecraft to see these worlds and their moons. Voyager 2's last planetary flyby was in 1989.

The two spacecraft continue to send scientific data from interstellar space; Voyager 1 passed into that region in 2012, while Voyager 2 did so in 2018. Voyager 1 is Earth's most distant spacecraft, currently around 15.9 billion miles (25.5 billion kilometers) away from us, according to NASA.

Two NASA astronauts installed the seventh and final set of mounting hardware for new sets of solar arrays during a successful 6.5-hour spacewalk outside of the International Space Station.

Jessica Meir and Anil Menon on Thursday (Aug. 6), assembled the modification kit for one of the space station's eight power channels, which will allow for the future addition of a new ISS Rolll-Out Solar Array (iROSA). Since 2021, astronauts on prior spacewalks have deployed six of the iROSA assemblies, leaving now just two awaiting delivery to the station later this year.

Like building a giant erector set, Meir and Menon worked to assemble and bolt together the triangular brackets on the 3B power channel, located on the far right, or starboard (S6) segment of the station's backbone truss. Menon was positioned on an articulating portable foot restraint (APFR) atop a worksite interface (WIFEX), providing a stable angle to work from the truss.

Once the modification kit structure was built and secured to the 3B mast canister, the two spacewalkers routed cabling that will carry the electricity from the future iROSA into the 3B power channel and then covered the struts with multi-layer insulation to protect them from micrometeoroid strikes.

The iROSA wings sit forward of the legacy solar arrays, augmenting their electricity generation rather than replacing it. The station's eight original arrays began showing degraded power output as they exceeded their 15-year design life. When used in tandem with the new iROSA wings, the upgraded system will increase the station's electricity supply by 20% to 30%.

The other power channel currently without an iROSA deployed is 2A on the left, or port side, of the station.

"Anil, you can see the moon to the — well, I am not sure what way you're facing, but…," said Meir, taking a short break during the spacewalk to notice NASA's next destination for astronauts under its Artemis program.

"To my right. Yeah, I see it — thanks for the heads-up," said Menon. "I can see a future moon base there."

"I can see it, too!" Meir said.

Meir later turned her attention to Mars with her closing words of the day.

"On this day in 2012, NASA's robotic rover Curiosity successfully landed on the surface of Mars with the goal of understanding if the planet could have fostered life. Curiosity achieved that goal within a year," she said. "One day, humans will visit Curiosity, propelled by the groundbreaking science, technology demonstrations and operations conducted here on the International Space Station for almost 26 years now."

"Today, we made one more step toward expanding the ISS power system, further sustaining our human presence in low Earth orbit, as we prepare to take those next steps," said Meir.

Thursday's spacewalk began at 8:33 a.m. EDT (1233 GMT) when Meir and Menon switched their spacesuits to internal battery power. After collecting their tools and reentering the Quest airlock, the spacewalk, or extravehicular activity (EVA), concluded at 3:00 p.m. EDT (1900 GMT), 6 hours and 27 minutes after it began.

This was the 96th U.S. EVA and 281st spacewalk overall in support of the International Space Station's assembly, maintenance and enhancement. It was the first career spacewalk for Menon and the sixth for Meir, bringing her total time on EVA to 42 hours and 33 minutes.

This was the first spacewalk for the space station's Expedition 75 crew. There are two more U.S. outings scheduled for this month: EVA 97 will work to replace a space-to-ground antenna on Aug. 13, and EVA 98 will connect power channel cables and data relay systems as part of ongoing maintenance, including preparations for the station's future deorbit, as well as replace a navigational aid used for spacecraft docking on Aug. 25.

NASA's Perseverance rover witnessed a rare event recently, when Earth briefly disappeared behind Mars' moon Phobos in the Red Planet sky.

What is it?

These new composite images were released by NASA's Jet Propulsion Laboratory (JPL) and taken on July 2, 2026, the 1,907th Martian day of Perseverance's mission. They consist of nine different images taken by the rover's Mastcam-Z instrument as it pointed up into the hazy Martian sky, watching our planet, seen here as a pale dot, cross behind the Mars moon Phobos.

This type of event is known as an occultation, from the Latin word occultare, meaning "to hide." On Earth, the most common type of occultation occurs when our moon passes in front of background stars or when planets pass behind the moon.

Mars has two moons, Phobos and Deimos. Phobos is the larger and innermost moon. Both are lumpy and irregularly shaped, and astronomers aren't sure whether they came from the asteroid belt or were formed from an ancient impact near or on the Red Planet.

Why is it incredible?

The image took careful preparation and required Perseverance to be in the right place at the right time.

"Phobos crosses the Martian sky three times a day, and Earth is visible for months at a stretch, but catching one directly behind the other takes planning and a little luck," said Mark Lemmon, a Mastcam-Z co-investigator at the Space Science Institute.

Aside from catching Earth passing behind Phobos, Perseverance has also witnessed Phobos passing in front of the sun, in what JPL calls a "Martian solar eclipse."

The next crew, spacecraft and rocket to fly to the International Space Station are on schedule to meet their mid-September launch date, mission managers and the astronauts told reporters on Monday (Aug. 3).

SpaceX's Crew-13 astronauts — commander Jessica Watkins and pilot Luke Delaney of NASA, mission specialist Josh Kutryk with the Canadian Space Agency and mission specialist Sergey Teteryatnikov of Russia's federal space corporation Roscosmos — will become only the second crew to fly aboard the Dragon spacecraft "Grace" when they lift off no earlier than Sept. 12 from Space Launch Complex-40 at Cape Canaveral Space Force Station in Florida.

They will then dock with the space station the following day to begin a seven-month stay on the orbiting outpost, as part of the Expedition 75/76 crew.

"We expect a very busy mission with lots of station maintenance, both internal and external, with a few EVAs [extravehicular activities, or spacewalks] on the docket," said Watkins, who is the only member of Crew-13 to have flown into space before and will become the first active NASA astronaut to fly on Dragon twice. "[We also expect] visiting vehicle capture and stowage operations, lots of science — very interesting science experiments that will be flying with us as well — and plenty of outreach."

Kutryk will be the fourth Canadian to serve on an ISS crew and the second from his country to fly this year, after Jeremy Hansen launched around the moon on the Artemis II crew in April.

"Personally, myself, I grew up on a cattle farm in Canada. It's a long way from being here with this mission in front of us, but the one thing that has resonated at every twist and turn in that journey has been the complexity of these missions and the enormity of the teams that go into pulling missions like this off," said Kutryk. "So, we need to say thank you to everyone."

Cybertrucks, spacesuits and mudflats

"Every time we do a human spaceflight mission, it gives us an opportunity to strengthen our understanding of low Earth orbit. It gives us an opportunity to broaden our international relationships and an opportunity to showcase to the world what we can do in low Earth orbit for human spaceflight," said Joel Montalbano, NASA's deputy associate administrator for human spaceflight.

During the mission, Watkins, Delaney, Kutryk and Teteryatnikov will take part in research to combat heart disease and Parkinson's disease by studying human stem cell-derived tissues. They will also explore crop production that's important for longer-duration spaceflight missions, and help improve scientists' understanding of blood flow abnormalities that are seen on long missions. The crew will also test new diagnostic medical equipment for keeping an eye on their overall health.

First, though, they must get to space.

"Final integration of the Dragon is complete. The capsule was stacked on the trunk just last week and mission preparations are proceeding well for a mid-September launch," said Dana Weigel, NASA's manager for its low Earth orbit program. "Falcon 9 booster maintenance will kick off this month. That same booster was flown on Crew-12. We are not tracking any major issues for this mission campaign."

This Friday (Aug. 7), the crew will don their SpaceX suits — the first "Rev. 3" models with improved donning and doffing capabilities, as well as adjustments to account for spinal growth on orbit — and get their first chance to board "Grace," their ride into orbit and back. This "test drive" will help them gain some muscle memory — some familiarity within the the vehicle mission — and provide them a very big psychological boost, managers said.

"Grace" will also sport new metal "mud flaps" for its Draco abort thrusters, replacing earlier carbon fiber models. In addition, should the crew encounter an emergency before launch, they will be evacuated from the launch pad area for the first time by Tesla Cybertrucks operated by SpaceX, reducing conflicts when SpaceX and NASA want to launch crewed flights at the near or same time.

"There was a lot of certification that had to go into making sure those Cybertrucks would start up with a gloved hand. There were a lot of tests in terms of making sure you could egress the vehicle with a bulky suit on," Richard Jones, deputy program manager of NASA's commercial crew program, said in a response to a question from collectSPACE and Space.com. "All of those things were proven to be already intact, and they're going to configure those Cybertrucks to be ready."

Departures and arrivals

The four members of Crew-13 will be sharing their time on the space station with outgoing and incoming Russian Soyuz crews, who will launch and land with members of Delaney's astronaut candidate class, "The Flies," selected in 2021.

"It's really exciting to see the class fly," said Delaney. "We're going to be meeting Anil [Menon] up there. He's part of our class. Deniz [Burnham] will come up right behind to replace him. Working closely with both of those two throughout astronaut training, it's really just satisfying."

"I'm slightly hoping we get delayed a little bit, so we have some overlaps, so that way we can have three Flies back to back, he said.

For Kutryk, some timing just cannot be controlled.

"It's about midway through — pretty much perfect timing. That's sarcasm," said Kutryk, referring to the upcoming birth of his third child, who is expected to come into the world while he is on the space station.

"It's been done a couple times before," he said, referring to NASA astronaut Mike Fincke and Randy Bresnik, who both had children born while on the ISS. "I think that my family is ready. I have a wonderful, huge support network, from my wife outwards, around us, and we're looking forward to that challenge and to the uniqueness of this experience."
