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.

CAPE CANAVERAL, Fla. (AP) — 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.

The SpaceX Crew-10 launch attempt was scrubbed Wednesday from Kennedy Space Center meaning two Boeing Starliner astronauts waiting to come home will have to wait some more.
