Here's how astronauts Butch Wilmore and Suni Williams physically managed to last 10 month at the International Space Station.

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.

NASA will wait at least another two days to launch its next space station crew, delaying the return of Starliner astronauts Barry "Butch" Wilmore and Sunita Williams a bit longer.
