科学家们希望能够更好的了解所谓的“太空天气”，“太空天气”有时会对地球天气或对地球轨道上的通信卫星造成破坏。

Scientists hope to gain a better understanding of so-called " space weather ," which can sometimes knock out weather or communication satellites orbiting the Earth .

中国发言人称今年送入轨道的主要是通信卫星，将在36000英尺的轨道上飞行。

A spokesman for the China Aerospace Science and Technology Corporation said thevessels going up this yt r will mostly be ' communication satellites ' orbitingat around 36000ft .

她在专业领域内出类拔萃，一定超乎常人，但由于宇航训练不足，当混乱不仅笼罩她的航天飞机，更笼罩了天外社区里一整层轨道空间站和通信卫星的时候，她彻底慌了。

She must have been an overachiever to reach a position of eminence in her profession , but her undertraining as an astronaut leaves her in a state of utter panic when chaos engulfs not only her shuttle but a whole tier of orbiting space stations and communication satellites in the extraterrestrial neighborhood .

1990年初开始提出利用静止轨道以外的其他轨道通信卫星的设想，最好是利用低轨道（LEO）卫星。

Now in the 1990 's it have been growing in using orbits other than the geostationary orbit for telecommunications satellites . It is the best approach to use the Low Earth Orbit ( LEO ) satellites .
