LEND Water South Pole

This image, created from data from the Lunar Exploration Neutron Detector (LEND) instrument, shows locations where fewer neutrons have been detected at the lunar south pole. The presence of hydrogen in the lunar soil reduces the number of neutrons that flow out from the Moon. To map out likely deposits of water ice, LEND scientists look for places that have fewer neutrons. Locations that appear blue suggest higher concentrations of hydrogen, and possible water ice.
