NASA astronauts Butch and Suni emerge from recovery after long Starliner mission
By Joey Roulette
WASHINGTON (Reuters) -Butch Wilmore and Suni Williams, the U.S. astronauts left on the International Space Station last year by Boeing's troubled Starliner capsule, are on the up after returning to Earth in March, emerging from weeks of physical therapy to ramp up work with Boeing and various NASA programs.
"Right now, we're just coming off of the rehab portion of our return," Wilmore, 62, told Reuters in an interview on Wednesday. "Gravity stinks for a period, and that period varies for different people, but eventually you get over those neurovestibular balance type of issues."
Wilmore and Williams, who last year set off for an eight-day Starliner test flight that swelled into a nine-month stay in space, have had to readapt their muscles, sense of balance and other basics of Earth living in a 45-day period standard for astronauts returning from long-term space missions.
The astronaut duo have spent at least two hours a day with astronaut strength and reconditioning officials within NASA's medical unit while juggling an increasing workload with Boeing's Starliner program, NASA's space station unit in Houston and agency researchers.
"It's been a little bit of a whirlwind," Williams, 59, said in the interview. "Because we also have obligations to all of the folks that we worked with."
Williams said some of her post-spaceflight side effects were slower to clear up and she felt tired in late stages of recovery, as dozens of various muscles re-engaged. That made it hard for her to wake up as early in the mornings as she likes, until a little more than a week ago.
"Then I'm up at four in the morning, and I'm like, Aha! I'm back," she said.
Wilmore had some issues with his back and neck before heading to space, being unable to turn his head all the way to the side, he said. That all went away in space where "you don't have any stress on your body."
When he returned in March, gravity greeted him with the neck pain he left on Earth.
"We're still floating in the capsule in the ocean, and my neck starts hurting, while we still hadn't even been extracted yet," he said, laughing.
The human body, evolved over millions of years in the gravity of Earth's surface, was not meant for spaceflight.
The absence of gravity triggers an array of physical effects over time, such as muscle atrophy or cardiovascular shifts that can cause a chain reaction of other health changes. Confinement in a small space and higher solar radiation in space, without the protection of Earth's atmosphere, have other effects.
STARLINER PROBLEMS
Propulsion system issues on Boeing's Starliner forced NASA to bring the capsule back without its crew last year and to fold the two astronauts into its normal, long-duration rotation schedule on the ISS.
Boeing, which has taken $2 billion in charges on its Starliner development, faces a looming decision by NASA to refly the spacecraft uncrewed before it carries humans again. Boeing spent $410 million to fly a similar uncrewed mission in 2022 after a 2019 testing failure.
Reflying Starliner uncrewed "seems like the logical thing to do," Williams said, drawing comparisons with Elon Musk's SpaceX and Russian capsules that flew uncrewed missions before putting humans aboard. She and NASA are pushing for that outcome, Williams added.
"I think that's the correct path," said Williams, who is "hoping Boeing and NASA will decide on that same course of action" soon.
Results from Starliner testing planned throughout the summer are expected to determine whether the spacecraft can fly humans on its next flight, NASA officials have said.

Shift4 appoints new CEO
This story was originally published on Payments Dive. To receive daily news and insights, subscribe to our free daily Payments Dive newsletter. Shift4 named founder Jared Isaacman as executive chairman after President Donald Trump abruptly dropped the executive's nomination to run NASA over the weekend, the digital processor said in a regulatory filing Thursday. "Mr. Isaacman will remain an executive officer and Class I member of the Board," the filing said. The change is effective on Thursday, according to the filing with the Securities and Exchange Commission. The Allentown, Pennsylvania-based payments processing company had selected Shift4 President Taylor Lauber to succeed Isaacman if Trump's December nomination was confirmed by the Senate, but the chamber never voted on it. Isaacman, who has been the company's CEO and chairman since it was founded in 1999, will retain his super voting shares in Shift4, according to the filing. Lauber said during an April earnings call that Isaacman would convert his class B and class C shares into class A shares, which are worth a single vote per share. That agreement was "subject to several conditions, including the ratification and confirmation by the U.S. Senate of Mr. Isaacman's appointment as administrator of the National Aeronautics and Space Administration," the SEC filing said. "As a result of this condition not being met, Mr. Isaacman is no longer required to reduce his voting shares." Isaacman had a 76% voting power ownership stake in Shift4, according toan April 30 proxy filing. Trump cited Isaacman's "prior associations" when he withdrew the NASA nomination. The president pulled the nomination over the Shift4 founder's past contributions to Democrats, according to a report from the New York Times. However, Isaacman suggested on a Wednesday episode o fthe All-In podcast that his ties to billionaire SpaceX and Tesla CEO Elon Musk cost him the nomination, Bloomberg reported. Musk may also have helped him win the nomination from Trump, given Isaacman's participation in past SpaceX missions. Recommended Reading Shift4 CEO likely to keep post

Physicists use AI to hunt for UAPs and UFOs
An international team of physicists has developed a new methodology to aid NASA and other government agencies in their ongoing investigations into unidentified aerial phenomena (UAPs). The result is a novel strategy integrating a specially designed artificial intelligence program that was partially inspired by the physicists' own hunt for elusive dark matter. More popularly known as unidentified flying objects or UFOs, UAPs aren't necessarily considered as outlandish as they were decades ago. Setting aside the various theories that point to mysterious visitors from another planet, analysis increasingly centers on determining more worldly explanations. UAPs are often explained by classified experimental aircraft, astronomical events, or simply a case of mistaken drone identity. Meanwhile, a small percentage of sightings continue to baffle experts. Over the last few years, the US government has attempted to present a more transparent approach to its UAP research, while the military continues a campaign to destigmatize reporting sightings among its ranks. In November 2024, Congress held a publicly televised joint subcommittee hearing about UAPs featuring a former US Navy rear admiral and NASA administrator. While not without its fair share of criticism, these and similar events are shifting the overarching narrative around unidentified aerial phenomenon. Researchers like Matthew Syzdagis at the University of Albany have followed this evolving discourse for years. An associate professor of physics focused on dark matter, Syzdagis recently began collaborating with over 30 colleagues around the world to determine if this approach to hunting dark matter could be adapted to the search for UAPs. Their results, published this month in the journal Progress in Aerospace Studies, offer a new interdisciplinary methodology to review the past and future UAP sightings. 'As this process moves forward, it's critical that future study of UAPs follows a rigorous, repeatable method that can be tested and confirmed by other researchers,' Syzdagis said in a statement. 'We aim to establish a roadmap for these efforts with this paper.' The team relied on an array of datasets and tools to build their framework, including publicly available Doppler weather information from the National Weather Service (NWS). The NWS data was used to corroborate observations from additional equipment and determine if any of them simultaneously recorded a given anomaly. They then utilized Cosmic Watch, a radiation-detection system, to assess if a target UAP observed by infrared cameras was accompanied by ionizing radiation. To help analyze the infrared data, Szydagis created a new software program called Custom Target Analysis Protocol (C-TAP) that utilizes machine learning alongside human verification to review individual camera frames on a pixel-by-pixel basis. Inspired by similar strategies used to scan for direct evidence of dark matter, C-TAP then flags and separates actual UAP observations from any digital noise. Finally, these results were overlaid with trigonometric calculations to exclude any known objects in the sky like satellites or the International Space Station. To test it all out, Szydagis and colleagues used their new methodology to review observable light and infrared images collected on a 2021 field expedition around Laguna Beach, California, amid a period of heightened UAP reports. In total, the team reviewed about one hour of triggered visible and night-vision video footage along with over 600 hours of infrared data and 55 hours of background radiation measurements. Of the multiple anomalies initially flagged, researchers were able to offer plausible and likely explanations for all sightings except for one—a collection of bright white dots inside a dark spot recorded across multiple videos. And even then, it seems unlikely that the UAP event was unique. 'At this point, none can be classified as true anomalies, although further study of remaining ambiguities may alter this conclusion,' the study's authors wrote in their conclusion. Moving forward, the team hopes their methodology will help more researchers around the world continue to vet UAP sightings on a scientific, unbiased basis. 'Given the longstanding, global nature of the UAP/UFO question, [and] the air safety and security implications of their presence… studying and understanding these phenomena is of great and urgent importance,' added University of Albany physics professor and study lead author Kevin Knuth.

Why Trump can't just quit Musk
A version of this story appeared in CNN's What Matters newsletter. To get it in your inbox, sign up for free here. A few years ago, when Elon Musk was turning heel to people worried about climate change, joining forces with Republicans and breaking up with Democrats, I wrote about how the government couldn't just quit him. It's still true now that Musk is breaking up with President Donald Trump, on whose candidacy Musk spent somewhere in the neighborhood of $300 million. Musk got a literal golden key to the White House and the opportunity to take a chainsaw to the federal bureaucracy from Trump in exchange for the friendship that campaign coin bought him. The Trump-Musk bromance, which burned hot during the campaign and for the first few months of Trump's second term in the White House, has now experienced what SpaceX might euphemistically call a 'rapid unscheduled disassembly.' Even if Trump all but demands that key back and the relationship can't be put back together again, a permanent divorce would necessarily be messy and drawn out. At one point as they were lobbing shots at each other on their respective social media platforms, Trump suggested canceling Musk's government contracts. Musk suggested not letting NASA use his SpaceX's Dragon Spacecraft. Both have retreated from those suggestions. As I wrote back in 2023: 'NASA needs his rockets. The Pentagon needs his satellites. The government needs for electric vehicles to access his network of chargers. Officials need his social media platform — Twitter, now called X — to communicate with people.' It's all still true, although Trump has no interest in electric vehicles, and a standoff over whether a massive tax bill should continue to incentivize Americans to buy electric vehicles may have contributed to their beef. There are still a growing number of Americans buying electric vehicles, and Tesla's charging network is a part of that infrastructure. If anything, the intervening years have made the government even more dependent on Musk and particularly SpaceX, which not only provides rockets to NASA, but also has the Starlink internet system, which is key to the Pentagon and has been floated as an option to improve coverage for rural America. SpaceX has gotten more than $20 billion in contracts from NASA and the Pentagon, according to CNN's Chris Isidore. Isidore also explains Trump can't just go to another rocket company. Replacing SpaceX on those contracts, however, is not realistic. That's because there is no other company available to replace it. For example, Boeing, the only other company able transport astronauts to and from the International Space Station (ISS), had problems on its only crewed flight last year. That required its Starliner spacecraft to return to Earth without two astronauts, who were stranded at the ISS for nine months instead of the planned trip of a handful of days. CNN's Jackie Wattles, who covers space, told me the government's reliance on SpaceX goes much further. 'It's hard to understate how crucial SpaceX's capabilities are for civil and military space endeavors,' Wattles said. 'NASA not only relies solely on SpaceX to get astronauts to and from the International Space Station, the space agency awarded SpaceX nearly $1 billion last year to develop a way to safely drag the ISS out of orbit when it's decommissioned — a move expected to happen in the early 2030s if not sooner.' She ticked off a number of ways in which the US relies on SpaceX: If the US does end up wanting to go to Mars, SpaceX's Starship, which is still in development, is the only vehicle designed for the purpose. The US is paying SpaceX $4 billion for moon landings. It's relying on SpaceX to dispose of the International Space Station in the future. SpaceX carries more payload for the military than any other company. It launches most US spy satellites, and the Pentagon plans to count on Starlink for connectivity. Plus, Starlink is now working on updating the technology the Federal Aviation Administration uses to manage US airspace, something that raised questions about conflicts of interest when it was announced, but now seems like one more thing binding the government to Musk. Musk's companies are at the mercy of federal regulators, as we explored with a look at the ethical minefield created by Musk's involvement with the Department of Government Efficiency. His Neuralink, which aims to implant chips in the brains of humans, will have to deal with the Food and Drug Administration. SpaceX has to deal with the FAA and other agencies. X, formerly Twitter, features in the oversight of the Federal Communications Commission. Tesla has been investigated by the National Highway Traffic Safety Administration. Trump's administration has shown no reluctance to use the cogs of government to go after perceived enemies. Just ask Harvard. But if Trump were to use government to attack Musk, it would be like something out of Vladimir Putin's playbook in Russia, where oligarchs rise and fall based on whether they are in favor with the government. 'Trump can go after (Musk's companies), but then it'll be pretty explicit that's what he's doing,' said the tech journalist Kara Swisher, appearing on CNN's 'The Situation Room' Friday. 'Then he'll look exactly like what people accuse him of, which is an autocrat,' Swisher said. It would hurt the country if Trump did target Musk, she said. In additoin to Tesla, SpaceX and Neuralink, she pointed to the importance of Musk's forays into AI. 'We really do need cogent, important guidance on AI as it goes forward,' Swisher said.
