Scientific paper

A conceptual design of a high-power, long-duration lunar rover powered by a laser beam is presented. The laser transmitter in lunar orbit consists of an SP-100 reactor prime power source providing 100 kW of electricity to a laser diode array that emits 50 kW of laser radiation. The laser radiation is beamed to the lunar surface where it is received by a GaAlAs solid-state, laser-to-electric converter. This converter provides 22.5 kW of electrical power to the rover vehicle for science, locomotion, and crew needs. The mass of one laser transmitter is approximately 5000 kg, whereas the mass of the rover power system is 520 kg. The rover power system is significantly less massive (23 kg/kW) than alternative rover power units.
