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.

Butch Wilmore and Suni Williams originally planned to go to space for just eight days but got stuck on the station after their Boeing Starliner spacecraft experienced problems.
