This preliminary mosaic of an Artemis III candidate landing site is composed of images selected to optimize illuminated terrain coverage. As a first step, the thousands of NAC images of the south pole were filtered to the region of interest and divided into square segments along the image track at 20 m/pixel to minimize file sizes and provide flexibility to use only illuminated portions of each image for mosaicking. To determine optimal image ordering, we used sub-solar longitudes to guide the image selection to ensure local areas had consistent lighting geometries. For a first pass at offset correction, we used the results of aligning most of the LROC NAC images poleward of 84° south as described in Wagner et al. 2022 (LPSC LIII, Abstract no. 2573). Each image segment was then map-projected at native image resolution (1 m/px) and images with sub-solar longitudes within 10° bins were mosaicked together. As a second pass at offset correction, we compared the sub-solar longitude mosaics to the LOLA shaded relief product (5 m pixel scale). The final mosaic is a 1 m/pixel 16-bit (unsigned word) GeoTiff masked along boundaries between images with different lighting and blended for a more “seamless” mosaic. This mosaic is composed of 103 NACs (235 image segments) and eight bins of 10°-20° of sub-solar longitude. We estimate the absolute positional accuracy to be 5 to 20 m.
