摘要： 围绕地球轨道的人造物体的数量日益增加,促使航天器的运行和飞行任务计划必须考虑到有碰撞的危险,特别对于载人飞行尤为重要。文内推演了空间碎片未来发展的情况和碰撞概率。空间飞行物体数目的进一步增长,必将导致和加快碰撞链式反应过程。

Abstract: The number of man—made objects orbiting around the earthhas become so high that collision risks have to be taken into account inthe mission planing and operation of spacecraft,especially of manned spa-cecrafts. In this paper,the scenarios for the future development of spacedebris and collision probabilities are derived. A further steady increase ofthe basic population would always lead to and speed up a chain reactioncollisions.
