To stay entertained and occupy their minds, astronauts do many things.
Many astronauts play games with their crewmates, watch movies,  and watch sunsets and sunrises from space.

Staying healthy and active is hugely important for astronauts because gravity is not working their muscles the same as it does on Earth. They can become weak.
Astronauts exercise every day by using equipment like exercise bikes and weight machines.

Astronauts sleep in sleeping bags that are attached to the side of the ship so that they are secure.
If an astronaut's bed isn't fastened down, it will just float away.

With no gravity, eating can be difficult depending on the food. You can't even salt your food or the salt will float away!
Some foods are made by adding water and some are similar to the food we eat on Earth.
Astronauts need to focus on staying healthy by eating nutritious foods to have energy to do their work.

Astronauts have to study, train, and work hard for about two years before going into space.
They begin their training at the Johnson Space Center in Houston, Texas, opened in 1961.
They spend a lot of time in class learning skills they need, training with other people they will work with once in space.
Each astronaut has their own job, they work as a team.
