NASA’s Artemis III site update reduces the landing-area set from 13 candidate regions to 9, announced in October 2024 and documented in the NTRS abstract under document ID 20250011660. The nine regions are 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. NASA says this downselection reflects current Artemis III constraints and prioritizes operational feasibility, terrain safety, and science value; it does not mean the removed regions are unusable for future exploration.
The technical implication is that Artemis III is being optimized for crew safety and risk mitigation in the lunar south polar environment, where illumination, terrain roughness, and access to scientifically valuable volatile-rich areas are tightly coupled. NASA explicitly states the update is specific to Artemis III and does not affect Artemis IV and later missions, which are expected to broaden access across more of the south polar region. For the Ark, this is a signal that early human lunar settlement will likely begin in a narrow set of highly constrained, high-value zones, making site characterization, autonomy, hazard mapping, and logistics resilience more important than broad geographic flexibility.
Ark action: preserve and continuously update the site-selection logic, hazard models, and regional geospatial datasets used to rank lunar south-pole landing zones, because these will become baseline inputs for habitation planning and emergency recovery. Track the nine candidate regions, the criteria NASA is using to exclude others, and any later site refinements tied to mission launch windows and transfer trajectories. Integrate this update into Ark planning for settlement siting, surface mobility corridors, resource prospecting, and long-term archival prioritization, since the first human foothold on the Moon will likely define the infrastructure geometry for decades.
The key takeaway is that NASA has narrowed Artemis III to nine south-polar candidate regions, establishing the practical launch point for humanity’s next lunar foothold and the Ark’s near-term preservation priorities.
