ESA Eyes Laser-Driven Moon Rover to Probe Ice in Permanently Shadowed Craters
A European concept named PHILIP would power a 250 kg lunar rover with a 500-watt infrared laser from a sunlit lander up to 15 km away, enabling operation in the Moon’s permanently shadowed, ice-rich regions by converting the laser into electricity with modified solar panels; the system also enables two-way data via a modulated retro-reflector, with field tests in Tenerife and plans for prototyping under ESA funding.
