With a fresh crew now aboard the International Space Station, the four fliers they are replacing — including long-delayed Starliner astronauts Barry "Butch" Wilmore and Sunita Williams — undocked early Tuesday for a long-awaited return to Earth,

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.
