After being stranded for more than nine months in space, Nasa astronauts Butch Wilmore and Sunita Williams are finally on their way back to Earth.

Their extended stay aboard the International Space Station (ISS) came to an end early Tuesday (Eastern Time) when they departed in a SpaceX capsule, along with two other astronauts. The capsule undocked while orbiting 260 miles (418 kilometers) above the Pacific Ocean and aimed for a splashdown off the Florida coast by early evening, weather permitting.
