Butch Wilmore and Sunita Williams will finally return to Earth after nine months 'stuck' in space. The NASA astronauts are awaiting rescue by SpaceX.

NASA's stuck astronauts are heading home now that a replacement crew has arrived at the International Space Station.

NASA stated that if weather permits, the SpaceX capsule carrying Wilmore, Williams and two other astronauts will undock from the space station early Tuesday and splash down off Florida's coast later that evening.
