Preparations are underway for another trip on board the Soyuz Spacecraft.
One cosmonaut and two astronauts - one from the U.S., the other from Canada.
Have you ever wondered what astronauts and cosmonauts do when they're not launching out of orbit or floating around the International Space Station? They're training on Earth.
Here's a Russian Cosmonaut - looks like he's just spinning around in a chair. But he's really training for zero gravity.
They also practice manual docking on a flight simulator. And in their down time, they play some pool.
Ground crews put the spacecraft into position on Monday. The next Soyuz crew is scheduled to take off Wednesday.
