Originally scheduled for a short mission, astronauts Sunita Williams and Butch Wilmore have been stranded in space for over eight months. They launched aboard Boeing’s new Starliner capsule last June for what was meant to be a one-week test flight.

The return of astronauts Butch Wilmore and Suni Williams, who went to the International Space Station on Boeing's faulty Starliner capsule last summer, depends on when Crew-10 arrives.

The change in the return schedule of Sunita Williams and Buth Wilmore stems from NASA’s decision to deploy Endeavor, a previously flown SpaceX capsule, for the upcoming Crew-10 mission.
