The Boeing Starliner spacecraft successfully completed its uncrewed flight back to Earth, NASA announced overnight. The return ended the Starliner’s most recent flight test months later than intended and leaves its original crew, NASA astronauts Barry “Butch” Wilmore and Suni Williams, aboard the International Space Station until next year.

SpaceX launched a crewed NASA mission on Friday to return two astronauts from the International Space Station, after technical issues with Boeing’s spacecraft extended their stay for nine months, leading SpaceX CEO Elon Musk and President Donald Trump to suggest they were stranded for “political reasons.”

The crew-swap mission will enable NASA’s Butch Wilmore and Suni Williams to return to Earth from the International Space Station.

Former NASA astronaut Cady Coleman delivers the latest on the SpaceX mission that will bring astronauts Suni and Butch home after nine long months in space. Sometimes a good mistake is exactly what you need to make a movie scene work.

NASA astronauts Sunita Williams and Butch Wilmore, stranded at the International Space Station for over nine months, will return to Earth on Tuesday evening, NASA announced in a statement. Williams and Wilmore are scheduled to travel back to Earth alongside Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov aboard a SpaceX Crew Dragon spacecraft.
