轨道碎片

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 .

其中对航天器威胁最大的就是空间碎片，包括微流星体和轨道碎片。

Most of the spacecrafts are suffering from the bad space environment , and the space debris , included meteoroid and orbital debris , imperiled the spacecrafts most .

目前各航天大国都在研究航天器风险评估技术，有些国家已经有了成熟的风险评估软件，可针对微流星体环境和轨道碎片环境分别对航天器进行风险评估。

So far many countries are researching the technology of risk assessment of space debris impact , some of them already have a risk code , which can be used to value the risk assessment for the spacecraft in both meteoroid and orbital debris environment .

事实是，我们有很多轨道的碎片，在每小时10至20万公里行驶。

The truth is we do have a lot of orbiting debris , and traveling at 10 to 20 thousand miles per hour .

太空轨道上碎片过多可能让人类无法发射新的卫星，而卫星已成为地球上人类生活不可或缺的部分。

Too much debris in orbit would make it impossible to launch the satellites that have become an indispensable part of life back on Earth .

为保证航天任务的顺利完成，必须采用一定的模型，对可能威胁目标轨道的空间碎片进行跟踪预测。

To insure the security of space mission , the dangerous big debris must be tracked and predicted .

在近地轨道，这些碎片的飞行速度大约为每秒7公里（合每小时25200公里）。

In low Earth orbits , they are travelling at about 7km a second ( 25200km / h ) .

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 .
