NASA researchers report that certain Earth microorganisms can survive in cold, permanently shaded areas near the Moon’s south pole. Their findings suggest that microbes brought by astronauts—or carried unintentionally during exploration—could persist in small lunar “niches” such as compact crevices and other shadowed refuges. Some locations may be no larger than a footprint, limiting how widely contaminants could spread.
The study identifies bacteria and fungi that remain viable for extended periods in these harsh conditions. One fungus, Aspergillus, shows particular resilience, with survival lasting more than a week in some scenarios. Other microbes are described as enduring for at least more than a day, depending on exposure and local conditions.
Across outlets, the main focus is the same: the survival of Earth life on the Moon is possible in specific shaded regions, but the extent and duration vary by organism and environment. The results raise concerns for future efforts to study “pristine” lunar chemistry and for mission planning related to NASA’s Artemis program, where contamination control and biological risk assessments are central.
