joshuark shares a report from Ars Technica: For the better part of two months last year, most of us had no idea how serious the problems were with Boeing's Starliner spacecraft docked at the International Space Station. A safety advisory panel found this uncertainty also filtered through NASA's workforce. [...] The Starliner capsule was beset by problems with its maneuvering thrusters and pernicious helium leaks on its 27-hour trip from the launch pad to the ISS. For a short time, Starliner commander Wilmore lost his ability to control the movements of his spacecraft as it moved in for docking at the station in June 2024. Engineers determined that some of the thrusters were overheating and eventually recovered most of their function, allowing Starliner to dock with the ISS. [...] Throughout that summer, managers from NASA and Boeing repeatedly stated that the spacecraft was safe to bring Wilmore and Williams home if the station needed to be evacuated in an emergency. But officials on the ground ordered extensive testing to understand the root of the problems. Buried behind the headlines, there was a real chance NASA managers would decide -- as they ultimately did -- not to put astronauts on Boeing's crew capsule when it was time to depart the ISS. [...] It would have been better, [Charlie Precourt, a former space shuttle commander and now a member of NASA's Aerospace Safety Advisory Panel (ASAP)] and other panel members said Friday, if NASA made a formal declaration of an in-flight "mishap" or "high visibility close call" soon after the Starliner spacecraft's troubled rendezvous with the ISS. Such a declaration would have elevated responsibility for the investigation to NASA's safety office. [...] After months of testing and analysis, NASA officials were unsure if the thruster problems would recur on Starliner's flight home. They decided in August 2024 to return the spacecraft to the ground without the astronauts, and the capsule safely landed in New Mexico the following month. The next Starliner flight will carry only cargo to the ISS. The safety panel recommended that NASA review its criteria and processes to ensure the language is "unambiguous" in requiring the agency to declare an in-flight mishap or a high-visibility close call for any event involving NASA personnel "that leads to an impact on crew or spacecraft safety."
