NASA and SpaceX on Friday will count down to a long-awaited crewed rocket launch that will allow them to bring home U.S. astronauts Butch Wilmore and Suni Williams, who have been stuck on the International Space Station for nine months.

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

The SpaceX Crew-10 launch attempt was scrubbed Wednesday from Kennedy Space Center meaning two Boeing Starliner astronauts waiting to come home will have to wait some more.
