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.

SpaceX Crew-10 mission successfully docked at the International Space Station, setting the stage to rescue two stranded NASA astronauts who have been stuck in space for months.

The two astronauts who crewed the Boeing Starliner have greeted their replacements, who docked Sunday morning at the International Space Station.
