近地空间对航天器来说是一个恶劣的环境。太空中的卫星暴露于诸如宇宙射线的单粒子效应、货车艾伦辐射带电子的内部充电以及在地磁暴和亚磁暴期间注入内磁层的热等离子体中的高能电子的表面充电等危险。这些地球物理现象变化很大，统称为空间天气。与这些危险有关的问题包括使命丢失、子系统故障、使命降级、数据丢失、幻象命令、虚假信号和单粒子效应（扰乱、闭锁和烧毁）。在这里，我们描述的物理现象，并给出了许多例子，他们对通信卫星的影响。
Space near Earth contains a hostile environment for spacecraft. Satellites in space are exposed to such hazards as single-event effects from cosmic rays, internal charging from Van Allen radiation belt electrons, and surface charging from energetic electrons in hot plasma injected into the inner magnetosphere during geomagnetic storms and sub storms. These geophysical phenomena are highly variable, and are collectively known as space weather. Problems associated with these hazards include loss of mission, subsystem failure, mission degradation, loss of data, phantom commands, spurious signals, and single-event effects (upsets, latchup, and burnout). Here, we describe the physical phenomena and give numerous examples of their effects on communications satellites.
