The pair of NASA astronauts who have been in space for over nine months returned to Earth on Tuesday after a new crew to replace them reached the ISS over the weekend.

NASA removed two astronauts from its Crew-9 mission to allow for Williams and Wilmore to join the cohort, and return onboard the SpaceX Dragon − which carries four people at a time. The altered Crew-9 − only Hague and Gorbunov − launched aboard the SpaceX Dragon Freedom in late September.

NASA astronauts Butch Wilmore and Suni Williams are set to arrive home on SpaceX after spending 9 months on the ISS after Boeing’s Starliner was sent back empty.
