Butch Wilmore and Suni Williams are heading home after about nine months at the International Space Station. The two veteran NASA astronauts were only supposed to be in space for a little more than a week.

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.

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.
