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.

Wilmore and Williams will return on the SpaceX Dragon Freedom, the same spacecraft that transported the Crew-9 astronauts to the ISS. The astronauts' return is not a rescue mission, as their extended stay was planned last summer to accommodate crew rotation and space station operations.
