Four astronauts will soon launch to the space station — a flight that will kick off a series of events culminating in the long-awaited return of NASA 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.

NASA will livestream the launch Friday night of Crew-10, which will in part replace the Starliner astronauts at the International Space Station.
