NASA has narrowed Artemis III south-pole candidate landing regions from 13 to 9. The updated set announced in October 2024 includes Peak near Cabeus B, Haworth, Malapert Massif, Mons Mouton Plateau, Mons Mouton, Nobile Rim 1, Nobile Rim 2, de Gerlache Rim 2, and Slater Plain. The original 13 regions, announced in August 2022, were each about 15 by 15 kilometers (9.3 by 9.3 miles), and the final landing area is expected to be a roughly 100-meter-radius site inside one of these regions.
The technical significance is concentrated at the lunar south pole, where permanently shadowed regions are believed to host water ice and other volatiles, while the terrain is heavily cratered, mountainous, and operationally unforgiving. A separate NASA update emphasizes the need for high-fidelity digital elevation models with less than 1 meter per pixel and less than 0.1 vertical error to support hazard avoidance, illumination modeling, landing ellipse definition, and traverse planning. For long-term habitation, this is a blueprint for where energy, water, mobility, and safety constraints intersect; for existential risk, it shows that survivable lunar infrastructure will depend on precision mapping and site-specific resource access, not generic polar presence.
The Ark should treat these regions as the highest-priority lunar testbed for settlement logistics, resource prospecting, and fault-tolerant surface operations. Monitor Artemis III site downselection, especially any site that converges on low-seismic, ice-adjacent terrain near Shackleton, Malapert, or de Gerlache, and integrate the mapping standards into Ark habitat siting criteria. Research must focus on regolith mechanics, shadow-ice accessibility, power continuity during long shadow periods, and transport corridors between landing zones and resource nodes.
