They have to be tied down to sleep, or they will float away. Eating can be fun because food is packed in bags and they use special spoons. I think the best part is looking out the window and seeing the beautiful blue Earth. However, astronauts have to exercise every day to stay strong. Life in space is exciting but also challenging. I would love to try it one day. 1 学科网（北京）股份有限公司 $
