当今世界,人类的科学技术日新月异,许多国家都把研究的领域扩展到了地球以外的世界,每年都有许多颗人造卫星被送入宇宙空间。人们不禁要问,那些运载火箭的塔层,那些失效的人造卫星,油缸,太空摄影附件都到哪儿去了呢?它们没有被地球回收,而是飘散在太空中。 太空中这些大件的金属垃圾沿太空轨道四处飘散,不时会碰在一起,散裂成数以百计的碎片,这些碎片又继续飘散,又会撞到其他金属拉圾而再次分裂,这样不断地循环撞击、
In today’s world, science and technology of mankind are changing with each passing day. Many countries have extended their research to a world beyond the earth. Many man-made satellites are sent into the universe every year. People can not help wondering where the rocket towers, those lapsed artificial satellites, oil tanks, and space photography attachments are gone. They are not recovered by the earth, but are scattered in space.
