The Boeing Starliner spacecraft successfully completed its uncrewed flight back to Earth, NASA announced overnight. The return ended the Starliner’s most recent flight test months later than intended and leaves its original crew, NASA astronauts Barry “Butch” Wilmore and Suni Williams, aboard the International Space Station until next year.

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.

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.
