NASA bumped up the return flight home plans for the SpaceX Crew-9 mission that includes a pair of astronauts who were left behind on the International Space Station by Boeing’s Starliner.

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.

The Starliner crew was originally meant to stay on board the ISS for a week, but issues with Boeing's Starliner spacecraft severely delayed their return to Earth.
