地球人造卫星和宇宙飞船在太空活动运行的过程中,由于各种不同的原因,会产生大小不等的金属碎片,称为太空垃圾。太空垃圾对人类的宇航事业,造成潜在威胁。科学家最近发明了“太空清道夫”卫星,体积只有足球那么大,重13磅,卫星上装备有4台小型侦察摄像机,一旦发现漂浮在太空的太空垃圾,“太空清道夫”就会自动跟踪依附过去,将那些漂浮的碎片推向大气层,在这个过程中,小卫星会迅 Earth satellites and spacecraft in space activities in the process of operation, due to a variety of reasons, will produce unequal sizes of metal fragments, known as space debris. Space junk poses a potential threat to human spaceflight. Scientists recently invented the “space scavenger” satellite, the size of only football, weighing 13 pounds, the satellite equipped with 4 small reconnaissance cameras, once found in space space debris, “Space Scavenger” will automatically follow the attachment In the past, those floating debris pushed to the atmosphere, in the process, the small satellite will be fast
