American company SpaceX's Dragon spacecraft arrived at the International Space Station last night to bring home two astronauts who were stranded there for nine months.
Butch Wilmore and Suni Williams are scheduled to return home this week with two other astronauts aboard the Dragon spacecraft.
Williams and Wilmore launched to the space station aboard a Boeing Starliner last summer and were scheduled to return eight days later, but the Starliner was deemed unsafe due to a fault in its pressurization system.
