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 Sunita Williams and Barry “Butch” Wilmore departed the International Space Station on March 18, ending an unexpectedly long space mission.

NASA’s two stuck astronauts headed back to Earth with SpaceX on Tuesday to close out a dramatic marathon mission that began with a bungled Boeing test flight more than nine months ago. Butch Wilmore and Suni Williams bid farewell to the International Space Station — their home since last spring — departing aboard a SpaceX capsule alongside two other astronauts.
