LAMP is a UV spectrograph investigation recently proposed for the LRO mission. Its three main objectives are to (i) identify and localize exposed water frost in permanently shadowed regions (PSRs), (ii) characterize landforms and albedos in PSRs, and (iii) demonstrate the feasibility of using natural starlight and sky-glow illumination for future lunar surface mission applications. A supplemental objective is to assay the lunar atmosphere and its variability. The LAMP spectrograph will accomplish these objectives by measuring the signal reflected from the nightside lunar surface and PSRs using the interplanetary HI Lyα sky-glow and FUV starlight as light sources. Both these light sources provide fairly uniform, but faint, illumination (e.g., the reflected Lya signal is expected to be ~ ˜10~R). Thanks to LAMP's sensitivity, however, by the end of the nominal 1-year mission the SNR for a Lyα albedo map will be >100/km2 in the polar regions, allowing the characterization of subtle compositional and structural features. LAMP is based on the flight-proven ALICE series of spectrographs that are flying on Rosetta and built for New Horizons.
