The crew-swap mission will enable NASA’s Butch Wilmore and Suni Williams to return home from the International Space Station.

The flight was scrubbed on Wednesday night, and the astronauts will return to the launchpad for their trip to the International Space Station.

NASA and SpaceX were on track to launch NASA's Crew-10 astronauts to the space station Friday night in a mission that will also aim to return Starliner astronauts Suni Williams and Butch Wilmore.
