President Trump on Tuesday announced that he has asked SpaceX founder Elon Musk to “go get” two NASA astronauts who have been aboard the International Space Station since June awaiting a return trip to Earth.

While Suni Williams and Butch Wilmore’s situation is unusual, their return trip will be pretty routine, as they were already slated to fly home on a SpaceX capsule as part of a scheduled crew rotation.

The founder of SpaceX said President Trump had asked his company to return two astronauts aboard the space station to Earth “as soon as possible.” NASA said it would do that “as soon as practical.”
