Abstract
ShadowCam is a National Aeronautics and Space Administration Advanced Exploration
Systems funded instrument hosted onboard the Korea Aerospace Research Institute
(KARI) Korea Pathfinder Lunar Orbiter (KPLO) satellite. By collecting
high-resolution images of permanently shadowed regions (PSRs), ShadowCam will
provide critical information about the distribution and accessibility of water
ice and other volatiles at spatial scales (1.7 m/pixel) required to mitigate
risks and maximize the results of future exploration activities. The PSRs never
see direct sunlight and are illuminated only by light reflected from nearby
topographic highs. Since secondary illumination is very dim, ShadowCam was
designed to be over 200 times more sensitive than previous imagers like the
Lunar Reconnaissance Orbiter Camera Narrow Angle Camera (LROC NAC). ShadowCam
images thus allow for unprecedented views into the shadows, but saturate while
imaging sunlit terrain.
