The Starliner spacecraft lost four thrusters while approaching the International Space Station last summer. NASA astronaut, Butch Wilmore took manual control, remembers Ars Technica, "But as Starliner's thrusters failed, Wilmore lost the ability to move the spacecraft in the direction he wanted to go..." Starliner had flown to within a stone's throw of the space station, a safe harbor, if only they could reach it. But already, the failure of so many thrusters violated the mission's flight rules. In such an instance, they were supposed to turn around and come back to Earth. Approaching the station was deemed too risky for Wilmore and Williams, aboard Starliner, as well as for the astronauts on the $100 billion space station.

But what if it was not safe to come home, either?

"I don't know that we can come back to Earth at that point," Wilmore said in an interview. "I don't know if we can. And matter of fact, I'm thinking we probably can't."
After a half-hour exclusive interview, Ars Technica's senior space editor Eric Berger says he'd heard "a hell of a story." After Starliner lost four of its 28 reaction control system thrusters, Van Cise and this team in Houston decided the best chance for success was resetting the failed thrusters. This is, effectively, a fancy way of turning off your computer and rebooting it to try to fix the problem. But it meant Wilmore had to go hands-off from Starliner's controls. Imagine that. You're drifting away from the space station, trying to maintain your position. The station is your only real lifeline because if you lose the ability to dock, the chance of coming back in one piece is quite low. And now you're being told to take your hands off the controls...

Two of the four thrusters came back online.

Wilmore: "...But then we lose a fifth jet. What if we'd have lost that fifth jet while those other four were still down? I have no idea what would've happened. I attribute to the providence of the Lord getting those two jets back before that fifth one failed...

Berger: Mission Control decided that it wanted to try to recover the failed thrusters again. After Wilmore took his hands off the controls, this process recovered all but one of them. At that point, the vehicle could be flown autonomously, as it was intended to be.
"Wilmore added that he felt pretty confident, in the aftermath of docking to the space station, that Starliner probably would not be their ride home," according to the article. And Williams says it was the right decision. Publicly, NASA and Boeing expressed confidence in Starliner's safe return with crew. But Williams and Wilmore, who had just made that harrowing ride, felt differently.

This week NASA "issued a solicitation for the next two private astronaut missions to the International Space Station," reports Space News. Scheduled after May of 2026 and then mid-2027, "These will be the fifth and sixth such missions to the ISS, part of a broader low Earth orbit commercialization effort by NASA with the ultimate goal of replacing the International Space Station with one or more commercial stations."

NASA's Space Station program manager calls the missions "a key part" of helping industry partners "gain the experience needed to train and manage crews, conduct research, and develop future destinations." In short, they see the missions "providing companies with hands-on opportunities to refine their capabilities and build partnerships that will shape the future of low Earth orbit." [NASA's call for proposals] offers an opportunity to have future missions commanded by someone other than a former NASA astronaut. While companies must propose a commander who meets current requirements, it can also propose an alternate commander who is a former astronaut from the Canadian Space Agency, European Space Agency or Japan Aerospace Exploration Agency with similar ISS experience requirements... ["Broadening of this requirement is not guaranteed," NASA warns.]

That could allow some former astronauts already working with commercial spaceflight companies an opportunity to command private astronaut missions. Axiom Space, for example, announced in July 2024 that former ESA astronaut Tim Peake had joined its astronaut team. That came after Axiom and the U.K. Space Agency signed a memorandum of understanding in October 2023 to study the feasibility of a private astronaut mission crewed exclusively by U.K. astronauts.
So far Axiom Space has been awarded all four private astronaut missions, according to the article, "flying one mission each in 2022, 2023 and 2024. Its next mission, Ax-4, is scheduled for no earlier than May."

But "While Axiom has little or no competition for previous PAM awards, it will likely face stiffer competition this time. Vast, a company also planning to develop commercial space stations, has previously stated its intent to submit proposals..."

NASA's SpaceX Crew-9 has returned to Earth safely after a stay of more than nine months aboard the International Space Station. The crew remained in space longer than expected due to issues with Boeing's Starliner capsule, which was originally scheduled to bring them home sooner.

While the mission has been politically fraught, the astronauts said in a rare space-to-earth interview last month that they were neither stranded nor abandoned. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..." CNN has more details on the arrival: Williams and Wilmore, alongside NASA's Nick Hague and cosmonaut Aleksandr Gorbunov of Russia's Roscosmos space agency, safely splashed down off the coast of Tallahassee, Florida at 5:57 p.m. ET. The crew's highly anticipated return came after the crew climbed aboard a SpaceX Crew Dragon capsule and departed the International Space Station at 1:05 a.m. ET. Williams, Wilmore, Hague and Gorbunov spent Tuesday morning and afternoon in orbit in the roughly 13-foot-wide (4-meter-wide), gumdrop-shaped SpaceX Crew Dragon spacecraft. Gradually descending, the capsule carried the astronauts from the space station, which orbits about 250 miles (400 kilometers) above Earth, toward the thick inner layer of our planet's atmosphere.

Around 5 p.m. ET, the Crew Dragon capsule began firing its engines to begin the final phase of the journey: reentry. This leg of the journey is considered the most dangerous of any flight home from space. The jarring physics of hitting the atmosphere while traveling more than 22 times the speed of sound routinely heats the exterior of returning spacecraft to more than 3,500 degrees Fahrenheit (1,926 degrees Celsius) and can trigger a communication blackout. After plunging toward home, the Crew Dragon spacecraft deployed two sets of parachutes in quick succession to further slow its descent. The capsule decelerated from orbital speeds of more than 17,000 miles per hour (27,359 kilometers per hour) to less than 20 miles per hour (32 kilometers per hour) as the vehicle hit the ocean.

After the vehicle hit the ocean, a SpaceX rescue ship waiting nearby worked to haul the spacecraft out of the water. Williams and Wilmore and their crewmates will soon exit Dragon and take their first breaths of earthly air in nine months. Medical teams will evaluate the crew's health, as is routine after astronauts return from space, before deciding next steps. Ultimately, the NASA crew members will return to their home base at Johnson Space Center in Houston. You can watch a recording of the re-entry and splashdown here.

A SpaceX Falcon 9 rocket launched a four-member crew to the International Space Station on Friday night, paving the way for NASA astronauts Butch Wilmore and Suni Williams to return to Earth after being there for nine months due to issues with Boeing's Starliner capsule. Arrival is set for late Saturday night. The Associated Press reports: NASA wants overlap between the two crews so Wilmore and Williams can fill in the newcomers on happenings aboard the orbiting lab. That would put them on course for an undocking next week and a splashdown off the Florida coast, weather permitting. The duo will be escorted back by astronauts who flew up on a rescue mission on SpaceX last September alongside two empty seats reserved for Wilmore and Williams on the return leg.

Reaching orbit from NASA's Kennedy Space Center, the newest crew includes NASA's Anne McClain and Nichole Ayers, both military pilots; and Japan's Takuya Onishi and Russia's Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free. "Spaceflight is tough, but humans are tougher," McClain said minutes into the flight. You can watch a recording of the launch here.

Wilmore and Williams aren't stranded on the International Space Station, and they weren't abandoned, the astronauts reminded CNN in a rare space-to-earth interview last month. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..."

As Christie's auction house planned the first-ever auction dedicated to AI-generated art works, over 5,600 people signed an online letter urging them to cancel it. "Many of the artworks you plan to auction were created using AI models that are known to be trained on copyrighted work without a license," the letter complained.

"These models, and the companies behind them, exploit human artists, using their work without permission or payment to build commercial AI products that compete with them. Your support of these models, and the people who use them, rewards and further incentivizes AI companies' mass theft of human artists' work." CNET reports that the signers "range from illustrators to authors to art therapists to cinematographers, from countries all across the globe."

Christie's ignored them all and held the auction anyways. So what happened when it was over on Wednesday morning? More than 30 lots attracted hundreds of bids and brought in $728,784, Christie's reports. And there's a generational twist: The auction house says 37% of registrants were completely new to Christie's, and 48% of bidders were millennials or members of Gen Z... The highest price in the sale was $277,200 for a work by Refik Anadol titled Machine Hallucinations — ISS Dreams — A. It used a data set of more than 1.2 million images taken from the International Space Station and satellites.
ARTnews reports that the auction actually brought in more than Christie's had expected: The sale, which made up of 34 lots, had an 82 percent sell through rate... While some digital artists, including Beeple, championed the sale, others decried it as emblematic of the ongoing struggle between human artistry and machine-driven innovation. The results, however, suggest that AI art — controversial as it may be — is carving a firm place in the market.

Axiom Space and Red Hat will collaborate to launch Data Center Unit-1 (AxDCU-1) to the International Space Station this spring. It's a small data processing prototype (powered by lightweight, edge-optimized Red Hat Device Edge) that will demonstrate initial Orbital Data Center (ODC) capabilities.

"It all sounds rather grand for something that resembles a glorified shoebox," reports the Register. Axiom Space said: "The prototype will test applications in cloud computing, artificial intelligence, and machine learning (AI/ML), data fusion and space cybersecurity."

Space is an ideal environment for edge devices. Connectivity to datacenters on Earth is severely constrained, so the more processing that can be done before data is transmitted to a terrestrial receiving station, the better. Tony James, chief architect, Science and Space at Red Hat, said: "Off-planet data processing is the next frontier, and edge computing is a crucial component. With Red Hat Device Edge and in collaboration with Axiom Space, Earth-based mission partners will have the capabilities necessary to make real-time decisions in space with greater reliability and consistency...."

The Red Hat Device Edge software used by Axiom's device combines Red Hat Enterprise Linux, the Red Hat Ansible Platform, and MicroShift, a lightweight Kubernetes container orchestration service derived from Red Hat OpenShift. The plan is for Axiom Space to host hybrid cloud applications and cloud-native workloads on-orbit. Jason Aspiotis, global director of in-space data and security, Axiom Space, told The Register that the hardware itself is a commercial off-the-shelf unit designed for operation in harsh environments... "AxDCU-1 will have the ability to be controlled and utilized either via ground-to-space or space-to-space communications links. Our current plans are to maintain this device on the ISS. We plan to utilize this asset for at least two years."
The article notes that HPE has also "sent up a succession of Spaceborne computers — commercial, off-the-shelf supercomputers — over the years to test storage, recovery, and operational potential on long-duration missions." (They apparently use Red Hat Enterprise Linux.) "At the other end of the scale, the European Space Agency has run Raspberry Pi computers on the ISS for years as part of the AstroPi educational outreach program."

Axiom Space says their Orbital Data Center is deigned to "reduce delays traditionally associated with orbital data processing and analysis." By utilizing Earth-independent cloud storage and edge processing infrastructure, Axiom Space ODCs will enable data to be processed closer to its source, spacecraft or satellites, bypassing the need for terrestrial-based data centers. This architecture alleviates reliance on costly, slow, intermittent or contested network connections, creating more secure and quicker decision-making in space.

The goal is to allow Axiom Space and its partners to have access to real-time processing capabilities, laying the foundation for increased reliability and improved space cybersecurity with extensive applications. Use cases for ODCs include but are not limited to supporting Earth observation satellites with in-space and lower latency data storage and processing, AI/ML training on-orbit, multi-factor authentication and cyber intrusion detection and response, supervised autonomy, in-situ space weather analytics and off-planet backup & disaster recovery for critical infrastructure on Earth.

How confident are we about the safety of commercial space tourism? Long-time Slashdot reader theodp writes: It's one thing for Microsoft to boast that they dare to use Outlook instead of Gmail. But it took a whole other level of commitment for Jeff Bezos to join his brother Mark aboard Blue Origin's first passenger-carrying mission in July 2021.

So, while Bezos is unhesitant about sending himself and other celebrities and loved ones into space aboard Blue Origin, how confident are you about the current state of space travel safety?

If offered a free ride into space from Bezos's Blue Origin, or one of the other options like Virgin Galactic, Axiom Space, or Boeing's Starliner, would you accept or decline it?

An anonymous reader shared this report from ABC News: Elon Musk called this week for the deorbiting of the International Space Station (ISS) "as soon as possible." "It is time to begin preparations for deorbiting the [ISS]," Musk wrote in a post on X on Thursday. "It has served its purpose. There is very little incremental utility. Let's go to Mars." In a follow-up post, Musk said he was planning to recommend to President Donald Trump that the station be brought down "as soon as possible" and that the 2030 timeline for deorbiting be moved up to two years from now.
Jordan Bimm, space historian and professor of science communication at the University of Chicago, told ABC News what he thinks was one of the most important findings to come out of ISS research: "that microgravity affects the body in lots of deleterious ways." "That leads to your bone loss, muscle loss, changes in the fluid inside our bodies that are normally being pulled down by Earth's gravity, changes to the eye and vision loss and things like that. We have gotten good data on how that progresses over time, and importantly, we have developed countermeasures for these things as well, including resistance training or running on a treadmill, things like that..."

Last June two NASA astronauts flew to the International Space Station on the first crewed test flight of Boeing's Starliner. But they aren't stranded there, and they weren't abandoned, the astronauts reminded CNN this week in a rare space-to-earth interview: "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck — and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.'

"That's what we prefer," he said...

[NASA astronaut Suni] Williams also reiterated a sentiment she has expressed on several occasions, including in interviews conducted before she left Earth. "Butch and I knew this was a test flight," she told CNN's Cooper, acknowledging the pair has been prepared for contingencies and understood that the stay in space might be extended. "We knew that we would probably find some things (wrong with Starliner) and we found some stuff, and so that was not a surprise," she said.
When Cooper opened the interview by asking the astronauts how they're doing, Williams answers "We're doing pretty darn good, actually," pointing out they had plenty of food and great crew members. And Wilmore added that crews come to the space station on a careful cycle, and "to alter that cycle sends ripple effects all the way down the chain. We would never expect to come back just special for us or anyone unless it was a medical issue or something really out of the circumstances along those lines. So we need to come back and keep the normal cycle going..."

CNN's article notes a new announcement from NASA Tuesday that the astronauts might return a couple weeks early "after opting to change the SpaceX Crew Dragon capsule it will use." That mission's targeted launch date is now March 12.

In the meantime, Williams says in the interview, "We do have some internet connection up here, so we can get some internet live. We've gotten football. It's been this crew's go-to this past fall. Also YouTube or something like that. It's not continuous — it has chunks of time that we get it. And we use that same system also to make phone calls home, so we can talk to our families, and do videoconferences even on the weekends as well. This place is a pretty nice place to live, for the most part."

And they're also "working on with folks on the ground" to test the NASA's cube-shaped, free-flying robotic Astrobees.

Friday the Orlando Sentinel covered NASA's 2024 mission-safety report from the Aerospace Safety Advisory Panel (formed in 1968). The report "commended the agency's handling of last year's beleaguered Boeing's Starliner mission [prioritizing astronaut safety], but revealed yet another issue found during the flight and questioned the agency's needs for the spacecraft in the future..." [The report] stated that it was unclear how a decision was made to waive a failure tolerance requirement on some of the thrusters without flight or qualification data to justify the decision. "These examples illustrate the panel's concern that, absent role clarity, risk management choices could unintentionally devolve to contractors, whose interests may not fully align with NASA's," the report warned...

It also revealed that in addition to the thruster and leak issues on the propulsion module driving the decision to fly home without astronauts, Starliner had a new issue as it made its way back to Earth. "Overall, Starliner performed well across all major systems in the undock, deorbit, and landing sequences; however, an additional mono propellant thruster failure was discovered in the crew module — distinct from the failures in the service module experienced during orbit," the report stated. "Had the crew been aboard, this would have significantly increased the risk during reentry, confirming the wisdom of the decision."

As far as Starliner's path to certification, the ASAP report said it would continue to monitor several unresolved issues with thrusters and seek information on how NASA and Boeing plan to get the spacecraft certified. "While the thruster issues have received considerable attention, the panel has previously noted other Starliner issues that require resolution prior to certification," it stated. That includes a battery redesign and work to strengthen the landing airbag apparatus. "Beyond these technical matters, schedule and budget pose substantial challenges to Starliner certification," the report added...

"Until the Starliner certification plan is well understood, it remains unclear as to whether a second provider will be available prior to the end of the ISS's operational life [in 2030]," the report stated.
The report "also suggested that NASA immediately adapt next-generation extravehicular mobility units, or EVUs," reports ExecutiveGov, "as current space suits astronauts use for operations outside the ISS are now beyond their design life."

NASA is planning to host a live Twitch stream next week from the International Space Station (ISS). "The stream, which takes place on February 12th at 11:45AM ET on NASA's Twitch channel, will feature Don Pettit, an astronaut currently on the ISS, and Matt Dominick, who returned to Earth from the ISS in October," reports The Verge. From the report: The astronauts will discuss "daily life aboard the space station and the research conducted in microgravity" and viewers will be able to ask them questions, according to a blog post.

"This Twitch event from space is the first of many," Brittany Brown, director of the Office of Communications Digital and Technology Division at NASA Headquarters in Washington, says in the post. "We spoke with digital creators at TwitchCon about their desire for streams designed with their communities in mind, and we listened. In addition to our spacewalks, launches, and landings, we'll host more Twitch-exclusive streams like this one."

Spirit Aerosystems builds aircraft components, including fuselages and flight deck sections for Boeing, according to Wikipedia. But now Boeing is set to acquire Spirit AeroSystems.

The aviation blog called Aviation Source News says the price tag was $4.7 billion, and opines that Boeing's move signals "a renewed focus on quality and supply chain stability" as Boeing "addresses lingering concerns surrounding its 737 program." Spirit's recent struggles with quality control and production delays have had a fallout effect for Boeing... By integrating Spirit's operations, Boeing can implement more stringent oversight and ensure consistent manufacturing processes. This move is a direct response to past quality lapses that have plagued the company and damaged its reputation. Beyond quality control, the acquisition also offers Boeing greater control over its supply chain. By bringing a key supplier in-house, Boeing can streamline production, improve coordination, and reduce the risk of future disruptions...

Spirit AeroSystems also supplies parts to Airbus, Boeing's main competitor. To address this, a separate agreement is being negotiated for Airbus to acquire Spirit's Airbus-related business. This strategic move ensures that Airbus maintains control over its own supply chain and prevents Boeing from gaining undue influence over its competitor's production.
Meanwhile, the vice president leading Boeing's Starliner spacecraft unit "has left his role in the program and been replaced by the company's International Space Station program manager, John Mulholland," Reuters reports, citing a Boeing spokesperson. In its first test mission last summer flying astronauts, Starliner was forced by NASA to leave its crew aboard the ISS and return empty in September over problems with its propulsion system. A panel of senior NASA officials in August had voted to have a Crew Dragon capsule from Elon Musk's SpaceX bring them back instead, deeming Starliner too risky for the astronauts.

Paul Hill, a veteran NASA flight director and member of the agency's Aerospace Safety Advisory Panel, said during a quarterly panel meeting on Thursday that NASA and Boeing continue to investigate Starliner's propulsion system. A Boeing spokesperson said on Thursday that the company and NASA have not yet determined what Starliner's next mission will look like, such as whether it will need to repeat its crewed flight test before receiving NASA certification for routine flights.

"Private space stations have been raising billions of dollars in an effort to build future hubs — and even one day cities — in orbit," according to a recent report from the U.K. newspaper, the Telegraph: Axiom Space, a US business aiming to build its own station, has raised more than $500m (£400m). Vast, a space business backed by crypto billionaire Jed McCaleb, is plotting two stations before the end of the decade. Gravitics, meanwhile, has raised tens of millions of dollars for its modular space "real estate". Nasa itself, along with other space agencies, is planning a further station, Lunar Gateway, which will orbit the Moon. Jeff Bezos's Blue Origin has also announced plans to build a space station by 2027, called Orbital Reef, which it has described as an orbital "mixed-use business park". Working with US aerospace business Sierra Space, Orbital Reef will be made up of inflatable pods, which can be launched on a regular rocket before being "blown up" in space. Sierra Space says these modules could house in-space manufacturing or pharmaceutical technology...

Since 2021, Nasa has also offered to pay hundreds of millions of dollars to private companies to develop commercial space stations that could succeed the ISS. So far, it has handed $400m to companies including Axiom, Blue Origin (which is working with Sierra Space), and Northrop Grumman... Vast hopes to launch its first space station, Haven-1, as soon as 2025. This simple module will be the first privately-run space station and will be occupied by a crew of four over four two week expeditions... While Vast was not one of the businesses to secure funding from Nasa, it hopes by launching the first proof-of-concept space station as soon as next year it can leapfrog rival efforts and claim the agency as an anchor customer. From there, it can target other space agencies or companies looking to conduct research.
Some interesting perspectives from the article:

• Chris Quilty, an analyst at Quilty Space: "If China were not building its own space station it is arguable whether Nasa would have felt enjoined to maintain a human presence in low Earth orbit."

• Tim Farrar, founder of TMF Associates, which advises some of the world's top space companies: "Unless they either secure government funding or focus on space tourism, they will inevitably have to rely on the largess of either billionaires or gullible investors who are space enthusiasts."

Thanks to Slashdot reader fjo3 for sharing the news.

fjo3 shares a report from the Washington Post: The International Space Station had to fire thrusters from a docked spacecraft last month to avoid a piece of debris that has been circling the globe for the nearly 18 years since the Chinese government blasted apart one of its own satellites in a weapons test. The evasive maneuver was the second in just six days for the space station, which has four NASA astronauts and three Russian cosmonauts aboard. That is the shortest interval ever between such actions, illustrating the slowly worsening problem of space junk in orbit. Debris is an increasingly vexing issue not only for NASA, but also for companies such as SpaceX and OneWeb seeking to protect the thousands of small satellites they send into space to provide high-speed internet. The debris cloud from China's 2007 destruction of the Fengyun 1C satellite remains one of the most persistent threats in orbit, with about 3,500 fragments still posing collision risks to spacecraft. Since 2020, the ISS has performed 15 debris-avoidance maneuvers.

The evasive maneuver was performed after a Space Force warning. According to the report, Space Force now tracks over 47,200 objects in orbit, issuing approximately 23 daily collision warnings -- up from just six per day five years ago.

Axiom Space has revised its plan for assembling its commercial space station by launching the Payload, Power, and Thermal module first, enabling it to operate as a free-flying platform as early as 2028 -- two years ahead of the original timeline. Space.com reports: NASA awarded Axiom Space a contract in 2020 to attach one or more modules to the International Space Station (ISS), which is set to retire by 2030 at the earliest. The original plan called for Axiom to detach a multi-module group from the ISS, creating a commercial outpost in low Earth orbit that will continue operating after the ISS is gone. But that plan has now been altered.

To create its space station, Axiom plans to launch five modules: a payload/power/thermal element, an airlock, a research/manufacturing hub, and a pair of habitat modules. The original plan was for Axiom to launch the Habitat 1 module to the ISS first, followed by the additional elements. The new assembly sequence will see the Payload, Power and Thermal module launch to the ISS first. This module could detach from the station -- and become a free flyer called Axiom Station -- as soon as 2028, according to the company. After that happens, Axiom will continue assembling the outpost, launching the Habitat 1 module to meet up with it. Habitat 1 will be followed by the airlock, the Habitat 2 module, and then the research and manufacturing facility. Angela Hart, a manager for the Commercial Low Earth Orbit Development Program at NASA's Johnson Space Center in Houston, said: "The updated assembly sequence has been coordinated with NASA to support both NASA and Axiom Space needs and plans for a smooth transition in low Earth orbit."

NASA has delayed the launch of SpaceX Crew-10 to late March 2025 to allow time for processing a new Dragon spacecraft, extending the stay of astronauts Butch Wilmore and Suni Williams on the ISS to about nine months. CNN reports: Williams and Wilmore launched to space in June, piloting the first crewed test flight of Boeing's Starliner spacecraft. Their trip, expected to last about a week, ballooned into a monthslong assignment after their vehicle experienced technical issues en route to the space station and NASA determined it would be too risky to bring them home aboard the Starliner.

The astronauts have since joined Crew-9, a routine space station mission originally slated to return to Earth no earlier than February after a handoff period with Crew-10. Now, Crew-10 will get off the ground at least a month later than expected because NASA and SpaceX teams need "time to complete processing on a new Dragon spacecraft for the mission," according to the space agency. "NASA and SpaceX assessed various options for managing the next crewed handover, including using another Dragon spacecraft," NASA noted in a blog post on Tuesday. "After careful consideration, the team determined that launching Crew-10 in late March, following completion of the new Dragon spacecraft, was the best option for meeting NASA's requirements and achieving space station objectives for 2025."

Scripps Research scientists sent stem-cell-derived brain organoids to the ISS to study the effects of microgravity on brain cells, finding that the organoids matured faster and showed signs of specialization compared to Earth-grown controls. The findings have been published in the journal Stem Cells Translational Medicine. Phys.Org reports: To examine how the space environment impacts cellular functions, the team compared the cells' RNA expression patterns -- a measure of gene activity -- to identical "ground control" organoids that had remained on Earth. Surprisingly, they found that the organoids grown in microgravity had higher levels of genes associated with maturity and lower levels of genes associated with proliferation compared to the ground controls, meaning that the cells exposed to microgravity developed faster and replicated less than those on Earth. "We discovered that in both types of organoids, the gene expression profile was characteristic of an older stage of development than the ones that were on the ground," [says co-senior author Jeanne Loring, Ph.D., professor emeritus in the Department of Molecular Medicine and founding director of the Center for Regenerative Medicine at Scripps Research]. "In microgravity, they developed faster, but it's really important to know these were not adult neurons, so this doesn't tell us anything about aging."

The team also noted that contrary to their hypothesis, there was less inflammation and lower expression of stress-related genes in organoids grown in microgravity, but more research is needed to determine why. Loring speculates that microgravity conditions may more closely mirror the conditions experienced by cells within the brain compared to organoids grown under conventional lab conditions and in the presence of gravity. "The characteristics of microgravity are probably also at work in people's brains, because there's no convection in microgravity -- in other words, things don't move," says Loring. "I think that in space, these organoids are more like the brain because they're not getting flushed with a whole bunch of culture medium or oxygen. They're very independent; they form something like a brainlet, a microcosm of the brain." "The next thing we plan to do is to study the part of the brain that's most affected by Alzheimer's disease," says Loring. "We also want to know whether there are differences in the way neurons connect with each other in space. With these kinds of studies, you can't rely on earlier work to predict what the result would be because there is no earlier work. We're on the ground floor, so to speak; in the sky, but on the ground floor."

An anonymous reader shared this report from Reuters: The rapid increase in satellites and space junk will make low Earth orbit unusable unless companies and countries cooperate and share the data needed to manage that most accessible region of space, experts and industry insiders said. A United Nations panel on space traffic coordination in late October determined that urgent action was necessary and called for a comprehensive shared database of orbital objects as well as an international framework to track and manage them. More than 14,000 satellites including some 3,500 inactive surround the globe in low Earth orbit, showed data from U.S.-based Slingshot Aerospace. Alongside those are about 120 million pieces of debris from launches, collisions and wear-and-tear of which only a few thousand are large enough to track... [T]here is no centralised system that all space-faring nations can leverage and even persuading them to use such a system has many obstacles. Whereas some countries are willing to share data, others fear compromising security, particularly as satellites are often dual-use and include defence purposes. Moreover, enterprises are keen to guard commercial secrets.

In the meantime, the mess multiplies. A Chinese rocket stage exploded in August, adding thousands of fragments of debris to low Earth orbit. In June, a defunct Russian satellite exploded, scattering thousands of shards which forced astronauts on the International Space Station to take shelter for an hour... Projections point to tens of thousands more satellites entering orbit in the coming years. The potential financial risk of collisions is likely to be $556 million over five years, based on a modelled scenario with a 3.13% annual collision probability and $111 million in yearly damages, said Montreal-based NorthStar Earth & Space...

[Aarti Holla-Maini, director of the U.N . Office for Outer Space Affairs], said the October panel aimed to bring together public- and private-sector experts to outline steps needed to start work on coordination. It will present its findings at a committee meeting next year. Global cooperation is essential to developing enforceable rules akin to those used by the International Civil Aviation Organization for air traffic, industry experts told Reuters. Such effort would involve the use of existing tools, such as databases, telescopes, radars and other sensors to track objects while improving coverage, early detection and data precision. Yet geopolitical tension and reluctance to share data with nations deemed unfriendly as well as commercial concerns over protecting proprietary information and competitive advantages remain significant barriers. That leaves operators of orbital equipment relying on informal or semi-formal methods of avoiding collisions, such as drawing on data from the U.S. Space Force or groups like the Space Data Association. However, this can involve issues such as accountability and inconsistent data standards.

"The top challenges are speed — as consensus-building takes time — and trust," Holla-Maini said. "Some countries simply can't communicate with others, but the U.N. can facilitate this process. Speed is our biggest enemy, but there's no alternative. It must be done."
Data from Slingshot Aerospace shows a 17% rise in close approaches per satellite over the past year, according to the article. (It adds that SpaceX data "showed Starlink satellites performed nearly 50,000 collision-avoidance manoeuvres in the first half of 2024, about double the previous six months...)

The European Space Agency, which has fewer spacecraft than SpaceX, said in 2021 its manoeuvres have increased to three or four times per craft versus a historical average of one."

India plans to build a moon-orbiting space station by 2040 that will support crewed missions to the moon and serve as a hub for scientific research. Space Magazine reports: If all goes according to plan, the lunar space station will be completed around the same time the nation's astronauts land on the moon, with construction of a permanent base on the surface before 2050. The lunar space station appears to be the third and final phase of India's moon exploration efforts. [...]

The lunar space station may be similar to the one India plans to build in Earth orbit, known as the Bharatiya Antariksh Station, or BAS. The development of this station's first module, BAS-1, was greenlit by the Indian government in September. Officials have said the first module will be launched to low Earth orbit by 2028, and the entire station will be operational by 2035.

"NASA has emphasized the ISS crew is in no immediate danger," reports Space.com. "The leaking area in the Russian segment of the orbital complex has been ongoing for five years," and "there was a temporary increase in the leak rate that was patched earlier this year..."

Former astronaut Bob Cabana emphasized that troubleshooting is ongoing during a brief livestreamed meeting on Wednesday. But NASA and Roscosmos "don't have a common understanding of what the likely root causes or the severity of the consequences of these leaks." "The Russian position is that the most probable cause of the cracks is high cycling caused by micro-vibrations," Cabana said, referring to flexing of metal and similar components that heat and cool as the ISS orbits in and out of sunlight. "NASA believes the PrK cracks are likely multi-causal — including pressure and mechanical stress, residual stress, material properties and environmental exposures," Cabana continued.

NASA and Russia disagree about whether "continued operations are safe", he added, but the remedy for now is to keep the hatch closed between the U.S. and Russian side as investigations continue.

The two agencies will continue meeting to seek "common understanding of the structural integrity", Cabana pledged, but he did not provide a timeline. Academic and industry experts will also be consulted.
