由于月球阻碍了与探测器的直接无线电通信，中国首先必须把一颗人造卫星送入月球轨道上的一个点，人造卫星可以从那里向航天器和地球发射信号。

Because the moon's body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot where it could send signals to the spacecraft and to Earth.

此外，由太阳活动引起的“地磁风暴”，确实可以破坏一些无线电通信，危害卫星，甚至瘫痪电力系统。

Additionally, it's also true that geomagnetic "storms" caused by solar activity can disrupt some radio communications, endanger satellites and even knock out power systems.

美国国家航空和航天局称，一场强烈的太阳活动已干扰无线电通信，可能在接下来的几天里中断电网、无线及卫星通讯。

A powerful solar eruption has disturbed radio communications and could disrupt electrical power grids, radio and satellite communication in the next days, NASA said.
