COVER Lunar Prospector evidence for water ice at the north (top) and south (bottom) lunar poles. Data on the rate of epithermal neutron emission from the lunar surface are color coded on two maps (overlaid by surface relief maps) poleward of ±70°. The dark blue and purple areas indicate low counting rates and are consistent with hydrogen-rich deposits covered by desiccated regolith. See the related Lunar Prospector Reports beginning on p. 1475. [Image: S. Maurice, Observatoire Midi-Pyrénées]
