太空垃圾对运行卫星的威胁越来越令人担忧。为保护卫星不受其危害,航天专家们提出了许多卫星防护措施,这里只简单地作一个介绍。在诸多的卫星防护方案中,有些明显不实际的不多赘述。比如,垃圾回收方案,在目前起码是极不经济的,并且对于非常小的垃圾回收是根本不可能的。为保护卫星不受附近物体的袭击,在其周围设一个禁区的方案也是不现实的,因为太空垃圾只受自然力的控制,靠明令禁止并不能改变其轨道。有些卫星防护措施尚存争议,比如设置处理轨道问题。其做法是把不再使用的卫星 The threat of space junk to satellites is becoming more and more worrisome. In order to protect the satellites from being jeopardized, space experts put forward many satellite protection measures, and this is only a brief introduction here. Among the many satellite protection programs, some are obviously unrealistic and not detailed. For example, garbage collection programs are, at the very least, extremely uneconomical, and impossible for very small garbage collections. In order to protect the satellites from nearby objects, it is also unrealistic to have a restricted area around them because space debris is controlled by natural forces and can not change its trajectory by prohibiting it. Some satellite protection measures remain controversial, such as setting the track to deal with the problem. The practice is to no longer use the satellite
