ELEMENTAL MAPPING OF THE MOON WITH THE SELENE GAMMA-RAY SPECTROMETER. R. C. Reedy 1 ,

Elemental maps of the Moon from gamma-ray spectrometers (GRS) orbiting the Moon have been very im-portant in understanding the origin and evolution of the Moon and its present state [1]. Previous GRS missions to the Moon have only mapped a few elements. Better elemental maps and maps of more elements are needed. Gamma-ray and other in-struments on upcoming lunar missions such as the Indian Chandrayaan-1 and the Japanese SELENE will provide such elemental maps. Gamma rays are the best probes of many ele-ments in the Moon [2]. The advanced GRS experiment on SELENE will map many elements and is described here.
