Spectral and Mineralogical Analysis of Planned CLPS Landing Sites with Lro-lamp

In anticipation of the Commercial Lunar Payload Services (CLPS) landed missions to regions of interest on the Moon as well as the lunar south polar region, we performed a series of spectral analyses and created FUV maps for each candidate region. 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. We will report LAMP imagery for these sites to aid in planning and upcoming data interpretation. Planned sites include the south pole, the Gruithuisen Domes, Reiner Gamma, and Mare Crisium. We compared LAMP data with ultraviolet, visible, and near-infrared spectral observations from two previous lunar missions, Clementine, and Kaguya as well as the most mineralogically and geologically relevant returned Apollo sample (and one Luna 24 sample). We produce Off/On-band albedo ratio maps with good signal to noise using the LAMP spectral mapping pipeline. Multiple regions of interest (ROIs) are selected at each site for comparison in both LAMP and previous mission data. Mare Crisium is more uniform in the FUV with some melt features, while the Gruithuisen Domes and Reiner Gamma both exhibit high FUV albedo ratios, pointing towards high feldspathic compositions (such as plagioclase) and space weathering. Melt features are highlighted and compared between the regions with contrasting compositions indicating differing subsurface lithologies and formation histories.
