Can Reflector Panel Technologies Tame Terrible Lunar Lighting Environments?

Abstract

This project investigated passive (non-powered) lighting countermeasures to improve lighting conditions where the Sun’s rays are nearly horizontal with the operational surface. NASA’s future missions are targeting the Lunar South Pole where “day” lasts for 2 weeks and the Sun is always on the horizon. The Sun’s collimated light creates harsh working conditions where the light is glaring when facing the sun, and deep long shadows are formed when turned away from the sun. The goal of this research was to determine if standard Commercial Off The Shelf (COTS) technologies, used by photographers, could increase the usability of an EVA crew member’s immediate surrounding work environment.
