Reflected Lyman-alpha sky-glow and starlight produce sufficient signal for even a small UV instrument like LAMP to see in the Moon's permanently shadowed regions.
The LAMP investigation offers to exploit this to:
- Spectrally identify the locations of any exposed water-ice deposits in the Moon's PSRs
- Directly map even the darkest PSRs
- Demonstrate the feasibility of low-light starlight/sky-glow vision applications for operational use on future landed missions.
LAMP is a low-risk, high-heritage investigation based on a rebuild of an existing instrument. LAMP offers to enhance the exploration and science value of LRO by:
- Addressing LRO-AO measurement objectives,
- Testing a novel polar/night vision system for future robotic and human landed missions
- Collecting lunar atmospheric science datasets that LRO would not otherwise obtain.
- Identify and localize exposed water frost in Permanently Shadowed Regions (PSRs).
- Collect landform-scale mapping in all PSRs.
- Demonstrate the feasibility of natural starlight and sky-glow illumination for future missions.
- (Supplemental) Assay the lunar atmosphere and its variability.
