问题    太空垃圾(space trash)是指那些绕着地球飞行的无用处的人造物体。这些物体在太空中不断碰撞，产生更多的太空垃圾，不仅给航天事业带来了巨大隐患，而且还污染了宇宙空间，给人类带来灾难。目前移除太空垃圾的方法主要有自然移除和人为移除，但效果都不理想。最好的方法就是从源头杜绝卫星成为太空垃圾的可能性，只有这样才能保证人类航天事业的可持续发展。
选项
答案    Space trash refers to those useless artificial objects that orbit around the earth. The constant collision of these objects produces even more trash in space, which not only causes huge hidden troubles to the astronautic project but also pollutes the cosmic space, and eventually brings disaster to human beings. Currently, the major methods to remove space trash are natural removing and artificial removing, both of which are not ideal. The most effective way is to eradicate the possibility that satellites become space trash from the very beginning. Only by doing so can we guarantee the sustainable development of astronautic project.
