The physical processes that characterize the interaction of high power microwave beams and the neutral and ionized regions of the Earth's aerospace environment are fairly well understood. Consequently it might be thought that predictions concerning both the degradation of SPS microwave beams that traverse the ionosphere and atmosphere, as well as the impact of energy losses from SPS beams on the Earth's environment can be readily obtained by model calculations. However, the parameters that characterize the natural background medium can themselves vary considerably and often in an unpredictable way. Furthermore, certain extreme conditions could conceivably lead to catastrophic failure of an SPS system. These conditions can arise through, for example, sudden enhancements in plasma density in the ionosphere due to solar flares and geomagnetic storms or from lightning flashes that raise the temperature of the lower ionosphere to tens of thousands of K. In this paper we examine the potential consequences of such phenomena on the performance of SPS systems.
