Abstract : Money is currently earmarked by Congress for laser augmented power for satellites. This means that satellites that are currently underpowered or have low PY efficiency may be rejuvenated by dosing them with laser power beamed from earth. In addition, Solar Thermal Propulsion schemes may be able to use laser power as an energy source in place of the sun when the sun's energy cannot be collected or is insufficient. Such cases include eclipses, earth's shadow, or other occlusions. Before we can say yes or no to this multiple use of laser power, we have several questions that must be answered. To answer these questions, we performed some simple laser power beaming experiments on existing solar thermal propulsion hardware. We will compare these data with data we get from strictly solar powered experiments using the same hardware. This paper is focused on the results from the laser power beaming experiment.
