NASA astronauts Sunita "Suni" Williams and Barry "Butch" Wilmore have been on the International Space Station for more than eight months, even though they initially expected to stay for just about eight days.

Hague and Gorbunov arrived at the station in late September, on SpaceX's Crew-9 mission. Williams and Wilmore have been in orbit since early June, when they launched on the first crewed mission of Boeing's Starliner spacecraft.
