NASA astronauts Butch Wilmore and Suni Williams have been in space since June 5, 2024 Highlights Boeing Starliner crew's return delayed by SpaceX mission NASA astronauts Wilmore, Williams stay on ISS until March SpaceX delay pushes back Crew-10 mission, altering schedules Advertisement NASA astronauts Barry Wilmore and Sunita Williams, who embarked on Boeing's Starliner spacecraft in June 2024, will now extend their stay on the International Space Station (ISS) until March 2025. The return, initially set for February, has been postponed due to a delay in SpaceX's Crew-10 mission, NASA confirmed on December 17. The decision was attributed to ongoing work on a new Crew Dragon spacecraft, as per official statements. Crew-10's Revised Timeline Crew-10, which will carry NASA astronauts Anne McClain and Nichole Ayers, along with JAXA's Takuya Onishi and Roscosmos cosmonaut Kirill Peskov, is now scheduled for a late-March launch aboard a SpaceX Falcon 9 rocket. This adjustment pushes back Crew-9's return, leaving Wilmore and Williams aboard the ISS for approximately nine months instead of the originally planned 10-day mission. The delay arose as SpaceX completes its latest Crew Dragon capsule, which is expected to arrive at NASA's Kennedy Space Center in January 2025 for final processing and testing. Steve Stich, Manager of NASA's Commercial Crew Program, stated in the official release that fabricating and integrating a new spacecraft requires meticulous attention to detail.
