Abstract

The Moon's permanently shadowed regions (PSRs) never see direct sunlight and are illuminated only by secondary illumination - light reflected from nearby topography. Modeling the secondary illumination enables our understanding of the illumination and thermal condition at the PSRs and can be computed for any point in time by using topography. The ShadowCam instrument onboard the KPLO spacecraft is now in the nominal mission phase, acquiring images of the PSRs. We compare the secondary illumination model generated images with true high-resolution images of the Shackleton PSR acquired by ShadowCam.
