Starliner's Space Station Flight Was 'Wilder' Than We Thought

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.

NASA Seeks Proposals for Two More Private Astronaut Space Station Visits

5 avril 2025 à 19:34
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..."

SpaceX Launches NASA's Crew-10 Mission To ISS

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..."

Axiom Space and Red Hat Will Bring Edge Computing to the International Space Station

✇Slashdot

8 mars 2025 à 22:34
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.

Elon Musk Urges Deorbiting the International Space Station 'As Soon as Possible'

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..."
