摘要
字面意义上的空间碎片指的是解体产生的碎片,但一般也包含火箭残骸、废弃卫星等各类无功能人造物体。随着人类探索、利用太空的步伐,空间碎片逐渐开始成为影响并威胁人类空间活动不可避免的问题。文章主要介绍空间碎片问题的起源、当前的状况、人们如何应对以及未来可能遇到的问题。
The concept of space debris,from the literal perspective,stands for the debris from breakup events,and has now been extended to various manmade objects in space,such as rocket bodies or satellites.Since the first day that human beings started to explore and utilize space,space debris has gradually become an unavoidable problem that affects and even threatens our future space operations.In this paper we describe the origin of the space debris,its current status,how we deal with it,and further problems that we may face in the future.
