Laser powering Moon rover from lander

ESA's PHILIP, ‘Powering rovers by High Intensity Laser Induction on Planets’, project explored powering a rover to explore perma-shadowed craters on the Moon via a laser mounted on a lander, from up to 15 km away. The light reflected to the lander from the rover could also be used for communication, with signal pulses introduced via a modulating retroreflector.
