The two astronauts who crewed the Boeing Starliner have greeted their replacements, who docked Sunday morning at the International Space Station.

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.

Four new astronauts arrived at the International Space Station aboard SpaceX's Crew Dragon on Sunday. Their arrival finally provides a way home for two NASA astronauts who have been on the ISS since June 2024.
