space-charge current

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.

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。
