空间碎片是人类进行空间活动而遗留在太空中的各类废弃物,如发射火箭、卫星、飞船等产生的多余物,以及空间物体之间碰撞而产生的碎块等。据中国航天空间碎片观测研究中心发布,经过多年跟踪观测,他们目前发现直径10厘米以上的碎片有数万个,而小于1厘米的碎片更是难计其数。毫无疑问,空间碎片的破坏力和杀伤力很大,那些体积较大,速度又快的碎片与同样运行速度很快的航天器相撞,两个加速度的叠加将会对航 Space debris are all kinds of wastes left in space by humans for their space activities, such as those generated by the launching of rockets, satellites, spacecraft and the like, as well as debris resulting from the collision between space objects. According to the China Spaceflight Observation and Research Center, after many years of follow-up observation, they now find that there are tens of thousands of fragments of more than 10cm in diameter, while fragments smaller than 1cm are even more difficult to predict. Undoubtedly, the destructive and lethal force of space debris is so great that those larger, faster fragments collide with similarly fast spacecraft, and the superposition of the two accelerations will make it to the air
