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.

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

Butch Wilmore and Sunni Williams have spent nine months aboard the International Space Station following the failure of Boeing’s Starliner mission. Their rescue rocket has finally been launched.
