人类在太空中完成了一次又一次伟大的壮举的同时,纯净的太空越来越不洁净了,“太空垃圾”便是这场征服外层空间的产物。运载火箭把航天器送到太空后,就完成了它的使命。星箭分离之后,火箭的剩余部分就在太空中游荡。各类航天器除可回收的一类之外(比如返回式卫星),其他的在太空中度过了设计寿命、丧失了功能之 While mankind has accomplished great feats again and again in space, pure space is becoming more and more unclean, and “space debris” is the product of this conquest of outer space. After the launch vehicle delivered the spacecraft to space, it completed its mission. After the separation of the stars and arrows, the rest of the rocket wanders in space. All kinds of spacecrafts, except for the ones that can be recycled (such as return satellites), have passed the design life and lost their functions in space.
