The two astronauts who crewed the Boeing Starliner have greeted their replacements, who arrived Saturday night at 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.

The replacements for NASA’s two stuck astronauts launched to the International Space Station on Friday night, paving the way for the pair’s return after nine long months. Butch Wilmore and Suni Williams need SpaceX to get this relief team to the space station before they can check out.
