Astronaut training

Astronaut training is a process that helps astronauts learn how to be safe and successful in space. Astronauts practice a lot of important skills so they know how to do a good job when they are in space. They practice things like how to work in a space suit, how to fly the spaceship, how to repair things outside of the spaceship, how to operate different tools, and how to make sure their body stays healthy in the weightlessness of space. They also practice how to work together as a team so they can accomplish their mission safely and successfully.
