Imagine flying to the moon or drifting among the stars in space. Some brave men and women called astronauts do just that. They travel into space to learn more about our world. What do you think it’s like to live and work in space? Let’s take a look. 2

Why Do Astronauts Go To Space? Astronauts ride in rockets that carry them through space. Some travel to a space station where they study the sun, Earth, and moon. Astronauts learn things about space that we didn’t know before. 3

What Do Astronauts Wear? Astronauts dress for their jobs. During take-off and landing, they wear suits that hold a mirror and a radio. If astronauts get into trouble, they can use these tools to show or tell others where they are. 4

Inside the space station, there is plenty of air to breathe, and the temperature is just right. The astronauts can wear shorts and T-shirts, just like they do on Earth. Outside the space station, there is no air, and it can be very cold. Astronauts wear suits that protect them and help them to breathe. 5

How Do Astronauts Sleep? Astronauts sleep in sleeping bags attached to the wall. That’s because there is no gravity— everything is light and bouncy. If they didn’t tie themselves down, their bodies would float around. 6

What Do Astronauts Eat? Astronauts eat many of the same foods in space as they do on Earth. They just add water or heat them up. Astronauts also bring foods that are ready to eat, like fruit and nuts. 7
Page 9
What Do Astronauts Do? Astronauts work hard. In the lab, they might study how things live and grow in space. Outside the space station, they fix parts of the station that have broken. Sometimes they try out new tools. 8

Astronauts must exercise in space or their bones will get soft. Some ride bikes that don’t move. Others run in place. Astronauts also like to have fun. They read, play games, and listen to music. 9
