在太空的飞船如果发生了危险怎么办?放弃飞船跳向地球?这听起来似乎过于疯狂了,但实际上,从太空直接跳下有可能就是未来航天员返回地球的一种方法。不管是运动还是救生,若直接从约10万米的高空跳向地球,听起来都像是天方夜潭——在下落的过程中要经受极高的速度和温度(这种高速高温使陨石都要燃烧),而 What to do if a spacecraft in space is in danger? Give up the spacecraft's jump to Earth? This may sound crazy, but in reality jumping directly from space could be a way for future astronauts to return to Earth. Whether it is exercise or life-saving, jumping directly from about 100 000 meters above sea level sounds like a night lake - to withstand the extreme speed and temperature during the fall (this high temperature causes meteorites To burn), and
