LRO LAMP Updated Global and Spectral Mapping Products Including Future CLPS Landing Sites

The Lunar Reconnaissance Orbiter’s UV Lyman Alpha Mapping Project (LAMP) instrument continues to collect high spatial and spectral resolution maps of the lunar surface into its fifth extended mission. LAMP is an ultraviolet imaging spectrograph that provides unparalleled UV coverage of regions of interest, including future Commercial Lunar Payload Services (CLPS) landing sites. Lacus Mortis and Mare Crisium are the planned landing sites for late 2022 and 2023 missions delivered by Astrobotic and Intuitive Machines. We will report LAMP imagery for these regions to aid in planning and upcoming data interpretation. The LAMP data are processed into both global spatial albedo maps and high-resolution spectral data products. We will discuss how LAMP’s data pipeline continues to produce spectral maps useful for studying and providing context to the geologic record, craters, lunar hydration features, and surface properties. Two LAMP data pipeline mapping tools that produce calibrated and corrected maps, the Global Mapper (GM) and Spectral Mapper (SM). The Global Mapper is used for producing global albedo raster maps, using standard equirectangular and polar stereographic projections matching LRO Lunar Orbital Laser Altimeter (LOLA) data projections, easily loadable into GIS tools. LAMP’s Spectral Mapper produces our high spectral resolution data product, containing observational parameters in spectral data cubes (albedo, phase angle info, brightness, integration time). Code improvements to the spectral mapper include photometric corrections and signal to noise filter refinement, with output to NetCDF to GeoTiff PDS4 compliant formats. In addition to spectral maps of the lunar poles and global spatial coverage, we are currently working on producing maps of CLPS sites, which will highlight LRO-LAMP’s utility in aiding landed missions in the coming years.
