NASA astronauts Sunita "Suni" Williams and Barry "Butch" Wilmore surely didn't think they'd still be on the International Space Station this long when they left Earth in June. In fact, they initially expected to stay for just eight days.

Two NASA astronauts flew to the International Space Station in June on Boeing's Starliner capsule. The test flight was planned for eight days but technical troubles forced the capsule to return empty.

A spokesperson with NASA, which oversees SpaceX’s flights to the ISS, said “NASA and SpaceX are expeditiously working to safely return the agency’s SpaceX Crew-9 astronauts Suni Williams and Butch Wilmore as soon as practical, while also preparing for the launch of Crew-10 to complete a handover between expeditions.”
