About this work
Test subjects performing subjective assessment of underwater lamp source during NBL Preliminary Lunar Lighting Evaluation. Divers at the Neutral Buoyancy Laboratory (NBL) in Houston are setting the stage for future Moonwalk training by simulating lunar lighting conditions. At the Lunar South Pole, the Sun will remain no more than a few degrees above the horizon, resulting in extremely long and dark shadows.
