NASA astronauts Barry Wilmore and Sunita Williams have been stuck in space for nine months, on what was originally going to be an eight-day mission.

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.
