Living in space for six months is not easy for astronauts. Life there is very different from that on Earth. 9. They have to stay in small rooms and use special machines to keep the air clean.
In space, there is almost no gravity. So astronauts can fly around instead of walking. 10. They must sleep in sleeping bags and tie themselves to the wall. If they don't, they will fly around at night.
Eating in space is also special. There is no fresh food like fruits or vegetables for a long time. 11. They also have to be careful not to let food fly into the machines.
Astronauts in space work for many hours every day. They do experiments, fix machines and take photos of the earth. 12. They exercise every day to keep their bones and muscles strong.
After six months, coming back to Earth is hard, too. 13. But they are always proud of their job. They help us know more about space and our planet.
