NASA Astronaut Hands Over Command of International Space Station

American Barry Wilmore set to return to Earth tonight.

— -- American astronaut Barry Wilmore has checked mostly everything off his to-do list in space.

The Soyuz will stay close to the ISS for about two revolutions of the Earth as it fires its engines to align with the landing site. The crew on board the spacecraft will then turn its de-orbit engines in the direction of travel and fire them for four to five minutes before falling back to Earth.

The atmosphere helps slow the Soyuz down until parachutes open and help the spacecraft glide toward a landing.
