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.

The delayed mission has reached the space station, the hatch has opened and soon the two astronauts who've been "stuck" in space can return home.
