Butch Wilmore and Suni Williams, who’ve been at the space station since June, will return to Earth along with two Crew-9 astronauts.

The pair of Boeing Starliner astronauts left behind on the International Space Station are finally on their way back to Earth after a planned eight-day trip turned into more than 9 1/2 months.

NASA astronauts Butch Wilmore and Suni Williams arrived at the ISS aboard Boeing's Starliner spacecraft last June. The duo were flying the capsule's first crewed flight test, which was expected to stay in orbit for about 10 days before flying the pair back to Earth.
