SpaceX aims to launch Crew-10 on Friday. The crew-swap mission will enable NASA’s Butch Wilmore and Suni Williams to return home from the International Space Station.

After their flight was scrubbed on Wednesday, four astronauts successfully lifted off, which will allow two NASA astronauts to return to Earth after an unexpected extended stay in orbit.

Sunita Williams and Butch Wilmore have completed over 900 hours of research involving 150 scientific experiments and technology demonstrations during their extended stay on the orbiting laboratory.
