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.

NASA's SpaceX Crew-10 members are aboard the Dragon capsule spacecraft in Florida for Wednesday night's mission to reach the International Space Station and retrieve astronauts Suni Williams and Butch Wilmore.
