Space travel is nothing new.The first spacecraft with a human was sent up into space in 1961.
Since then,people have not only traveled to space,but many of them have also lived there in space stations for some time.
The Soviet Union sent the first space station into space in 1971.This space station was called Salyut I.Salyut I was designed as a place where people could live while they observed space and did experiments.The first group of astronauts lived there for 23 days.The Soviet Union went on to make seven more Salyut space stations.At about the same time,the United States built its own space station,called Skylab.
Astronauts visited and often lived in these space stations for a short time.However,it wasn’t until the late 1980s when the Soviet Union sent the Mir space station that people began to live in space for a longer time.Mir stayed in space from 1989 until 2001,when it was decided that the space station was too old and no longer safe to live in.
Living in apace stations seems to be fun,but astronauts face many problems.One of them is food.All the meals on space stations are put together on Earth and sent there by space shuttle.Because the food has to last a long time (sometimes up to three months),a lot of it has to be stored in cans.The space station does not have a fridge,but it has a cool room to keep fruit and vegetables fresh.Astronauts also eat many other foods such as dried meat that do not need special care.
Without the help of gravity,sitting down to eat can be tough.Astronauts sometimes have to fix themselves to the wall while eating.They also have to be very careful to that food does not float away.

太空旅行是什么新鲜事.第一个宇宙飞船与人类送入太空是在1961年.
自那时起,人们不仅前往太空,但他们中的许多人也住在空间站有一段时间.
苏联把第一个空间站于1971年进入太空.这被称为礼炮号空间站I礼炮号我被设计为一个地方,人们可以住在他们观察空间和做了实验.第一批宇航员在那儿生活了23天.苏联继续让七礼炮号空间站.大约在同一时间,美国建造自己的空间站,称为太空实验室.
宇航员访问和经常住在这些空间站很短一段时间.然而,直到1980年代后期当苏联和平号空间站发送,人们开始在太空生活的更长时间.米尔留在空间从1989到2001年,当它被决定,空间站太陈旧,不再安全的住在.
生活在快速地站似乎很有趣,但是宇航员面对许多问题.其中一个是食物.在空间站里所有的食物放在一起在地球和发送通过航天飞机.因为食物必须持续很长时间(有时长达三个月),很多都是储存在罐子.空间站没有冰箱,但它有一个凉爽的地方保存水果和蔬菜的新鲜.宇航员也吃很多其他食物如风干肉,不需要特别的照顾.
不要让重力,坐下来吃东西是很困难的.宇航员有时不得不自己解决吃饭时的墙.他们还必须非常小心,食物不会漂走.
