Power Beaming from Lunar Orbit for Small Science Landers

A proposal for future small science mission to the moon envisions a network of small landers spread across the lunar surface, at latitudes ranging from equatorial to near polar landing sites. To provide power across the lunar nighttime, when solar power is not available, we analyze a proposal to power such small landers from orbit, using a laser to direct power from an orbital power station to photovoltaic arrays on the landers that are tuned to the laser wavelength. The approach is seen to be feasible, and conops for the system were outlined and a design for the spacecraft put together. To provide power to landers at any location, three orbital stations are required, each carrying a 3-kW laser.
