Nasa’s two stuck astronauts headed back to Earth with SpaceX on Tuesday to close out a dramatic marathon mission that began with a bungled Boeing test flight more than nine months ago.

Butch Wilmore and Suni Williams bid farewell to the International Space Station — their home since last spring — departing aboard a SpaceX capsule alongside two other astronauts.
