What is life really like in space? And what do astronauts do there?Astronauts living in space have the same hygiene needs as people do on Earth. When they wake up, they wash their hair, brush their teeth and go to the bathroom as well. However, because of microgravity(微重力), astronauts take care of themselves in different ways. For example, they use a kind of special matter to wash their hair and leg restraints(腿部固定装置)to position themselves when they use the toilet. Astronauts eat three meals a day: breakfast, lunch and dinner. Some food can be eaten in the natural form, such as fruit. Other foods require adding water such as noodles. There are no fridges in space, so space food must be stored and prepared properly to avoid going bad. Besides morning routine(常规)and eating in space, astronauts perform many tasks including checking the machines, updating computer equipment(更新电脑设备), etc. At the same time, the control center on the earth sends messages to the astronauts through voice or email with new instructions to assist them in their daily routines. Whats more, living in space is not just all work and no play. A popular way of relaxation is looking out of the window. And they can also enjoy themselves by watching movies, reading books, playing cards and talking to their families during their free time. 11.
