空洞

This artificially induced plasma depletion can then be used to investigate other space phenomena, such as the growth of the plasma instabilities or the modification of radio propagation paths. The 47 second OMS burn of July 29, 1985, produced the largest and most long-lived ionospheric hole to date, dumping some 830 kg of exhaust into the ionosphere at sunset. A 6 second, 68 km OMS release above Connecticut in August 1985, produced an airglow which covered over 400,000 square km.

这一人工诱导离子损耗之后能够被用于研究其他的太空现象，比如离子不稳定性的增长或者无线电传播通道的改变。1985年7月29日47秒的轨道操纵系统的燃烧产生了迄今为止最大和最长期的电离层空洞，将大约830公斤的废气在日落时倾倒入电离层。1985年8月康涅迪格上空6秒种、68公里的轨道操纵系统的排放产生了覆盖40万平方公里的气辉。
