English: LAMP is one of seven instruments aboard NASA’s Lunar Reconnaissance Orbiter spacecraft

LAMP is an imaging ultraviolet spectrometer based on an instrument that is currently.on its way to Pluto (the ALICE UV spectrometer). The instrument detects ultraviolet.light between 1,200 – 1,800 Å. Building up data over the course of the mission will allow surface resolutions of a few kilometers with high signal-to-noise ratio.

The Lyman-Alpha Mapping Project (LAMP) will search for surface ice and frost in the polar regions and provide images of permanently shadowed regions illuminated only by starlight and the glow of interplanetary hydrogen emission, the Lyman-Alpha line. Permanently shadowed regions on the moon's surface, such as the bottoms of some of the deep craters at the lunar poles, are very cold and might hold water ice. The Lyman-Alpha Mapping Project (LAMP) was built and developed at the Southwest Research Institute in San Antonio.
