Paper Abstract

Space operations present the human visual system with a wide dynamic range of images from faint stars and starlit shadows to un-attenuated sunlight. Lunar operations near the poles will result in low sun angles, exacerbating visual problems associated with shadowing and glare. We discuss the perceptual challenges these conditions will present to the human explorers, and consider some possible mitigations and countermeasures. We also discuss the problems of simulating these conditions for realistic training.
