在航天技术飞速发展的今天,太空行走已不算什么新鲜事了,尤其是美国和俄罗斯航天员,为了建造和修理空间站,经常出舱漫步,进行各种试验和维修工作,一呆就是几个小时,如履平地。其实,太空行走是风险很大的一项航天活动,因为太空环境非常恶劣:没有气压,没有氧气,阳光下温度高达120℃,背阴处温度低于零下100℃,还有大量的宇宙辐射。因此,在太空行走时必须使用 Nowadays, with the rapid development of space technology, space walking is nothing new, especially the astronauts of the United States and Russia. In order to construct and repair the space station, they often go out for sampans and carry out various tests and maintenance work. Hours, as flat. In fact, space walking is a very risky aerospace activity because the space environment is very harsh: no air pressure and no oxygen. The temperature in the sun is as high as 120 ° C, the temperature in the shady area is below minus 100 ° C, and there is a lot of cosmic radiation. Therefore, it must be used while walking in space
