- Abstract
Our team is funded by NASA PDART to produce updated geologic maps of the Apollo 15-16-17 landing sites at regional (1:200,000) and landing site (1:24,000) map scales for publication in the USGS SIM series. Our new maps will incorporate findings and interpretations from nearly 50 years of studies of the original Apollo data, surface observations, and sample analyses, as well as recent remote sensing data. Task 1. Renovation of Pre-Mission Geologic Maps: We have renovated the regional (1:250,000) and landing site (1:50,000) maps for Apollo 15, 16, and 17 pre-mission geologic maps in ArcMap and are in the process of finalizing the GIS file submission to the USGS for archiving. Task 2. Updating the Geologic Map of Apollo 15-16-17 Landing Sites: Mapping of the updated geologic maps continues in year 2 with the focus on defining point features and structural/linear features. We have also included Kaguya Terrain Camera mosaics as supporting data for mapping regional features. Task 3. Determine crater derived ages for new units: Craters =500 m have been mapped on the regional (1:200,000) Lunar Reconnaissance Orbiter Wide Angle Camera basemaps and craters =10 m have been mapped on the Narrow Angle Camera (NAC) basemaps for each landing site (1:24,000). Once map units are defined, these counts will be used to interpret unit ages on each map.
