NASA astronaut Suni (Sunita) Williams retires after 27 years; final ISS mission extended by Starliner failures
Suni Williams retired from NASA effective 27 December 2025 after a 27-year career. Her final mission aboard the International Space Station was extended when Boeing's Starliner suffered failures, keeping her and crewmate Butch Wilmore aloft until their March 2025 return aboard a SpaceX spacecraft after 286 days in orbit.
