Space Power Systems-What Will be Their Impact on the Upper Atmosphere and Ionosphere.
Abstract
Space power systems are currently receiving widespread attention because of the significant contributions that they could make toward meeting our country's energy needs in the 21st century. Although the systems are environmentally 'clean' relative to alternative or complementary concepts, some effects may be produced in the earth's atmosphere and ionosphere that could ultimately have impact on other activities of our society and on the biosphere as a whole. Specifically, we must consider (1) interactions of the microwave radiation with the thermosphere and ionosphere, and (2) pollution of the entire atmosphere up through the thermosphere as a result of the high volume of space traffic that will be required to construct and then service and maintain the power satellites. Microwave propagation effects could result in ionospheric modification that would have adverse effects on communications systems. Pollution effects, particularly in the stratosphere, could lead to changes in the spectral properties of ultraviolet radiation at the earth's surface, which would alter a number of biospheric processes. These factors must be taken into account in the design and development of space power systems so as to minimize their impacts. In addition, since the pollution problem is not unique to power satellites alone, a careful assessment of this problem is necessary taking into account all advanced space systems concepts that require a high level of support by space transportation vehicles.
