NASA researchers reported in Science Advances that several microbial types that could hitchhike on upcoming Artemis missions may survive in the Moon’s permanently shadowed regions near the south pole. The study examined microorganisms’ survival under lunar-relevant cold and radiation exposure conditions. The analysis focuses on contamination risk: if viable microbes are transported to the Moon’s surface, they could complicate scientific efforts to understand lunar history and planetary processes. NASA said it is a concern precisely because Permanently Shadowed Regions can act as long-term traps for conditions that preserve microbes in a dormant state. The findings come as the agency prepares for human landings and the establishment of future lunar infrastructure. For life-science stakeholders, the work emphasizes the need to treat planetary protection as an operational requirement rather than a one-time clearance step. The report is also likely to influence how mission teams plan for cleanliness assurance, sampling protocols, and waste-handling procedures across Artemis missions.
