这就是为什么这项新政策还包含了更新美国政府现行轨道碎片减缓标准的指导方针,该方针要求发射卫星或航天器的任何实体积极分析其所有行动产生空间碎片的可能性,无论是意外故障还是正常操作。
That 's why this new policy also includes directions to update the current U.S. Government Orbital Debris Mitigation Standard Practices , which already require any entity that launches a satellite or spacecraft to vigorously analyze the likelihood that any of their actions , from an unexpected failure or normal operations , will create more space debris .

此时地球与坦普尔塔特尔彗星轨道相交,该彗星轨道的碎片进入地球的轨道,与大气层摩擦,最后燃烧蒸发,这样我们就看到了狮子座的流星雨。
It occurs when Earth crosses the orbital path of Comet Tempel-Tuttle , which , like all comets , litters its orbit with bits of debris . It 's when this comet debris enters Earth 's atmosphere , and vaporizes , that we see the Leonid meteor shower .
