NASA astronauts Sunita "Suni" Williams and Barry "Butch" Wilmore have been on the International Space Station since June, even though they initially expected to stay for just eight days. But now, NASA might bring the two astronauts home several weeks earlier than expected.

Two NASA astronauts, stranded at the International Space Station since June, could return to Earth weeks earlier than originally planned after SpaceX agreed to swap capsules for its upcoming flights.

After Elon Musk said SpaceX would rescue the “stranded” Starliner astronauts, NASA moved their return date up by two weeks — a slight adjustment to a plan that had already been in place for months.
