Can Reflector Panel Technologies Tame Terrible Lunar Lighting Environments?

This project investigated the usage of reflector panel technology to redirect collimated sunlight to make it more usable for the lunar surface EVAs. When astronauts travel to the Moon’s South Pole, they will find a terrible exterior work environment to carry out EVA tasks. The location creates a situation where collimated light from the Sun illuminates the surface at low inclination angles, and the problem that the crew will often shadow their own workspace. Artificial lighting countermeasures will be marginally beneficial because the Sun’s illumination level is orders of magnitude higher than intensities possible from battery driven lighting systems. These conditions will persist because the latitude of the polar worksite, and the Moon’s orbit around the Earth. Photographers, on Earth, battle similar problems in their studios and outdoor worksites. To solve this problem, they use large portable reflectors to redirect light towards the object they are imaging.
