据报道,美国计划于90年代末发射的国际空间站,面临中等尺寸空间垃圾撞击的危险。这种尺寸的垃圾多为直径1～10厘米的碎片。这种空间垃圾之所以最危险,原因是:对于空间站的金属防护层来说,这些尺寸的垃圾太大,无法使它们偏离空间站或失效;就地面雷达而言,这些垃圾的尺寸又因太小而无法跟踪,致使空间站不能采取躲 It is reported that the United States plans to launch the ISS in the late 1990s at risk of being hit by garbage at a medium size. Most of the garbage of this size is 1 to 10 cm in diameter. The reason this type of space was the most dangerous was that these sizes of rubbish were too large for space station metal shields to deflect them from space stations or to fail; in the case of ground radars, the size of the rubbish was too small And can not track, resulting in space station can not take shelter
