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.

The Crew-9 mission, consisting of NASA astronauts Nick Hague, Suni Williams and Butch Wilmore, along with Roscosmos cosmonaut Aleksandr Gorbunov, is set to return to Earth after a brief handover period with the newly arrived Crew-10 expedition crew, pending weather conditions at the splashdown sites off the coast of Florida.
