Microbial survival risks in lunar exploration

Overview

Research indicates that Earth-based microorganisms could potentially survive in the extreme cold of the Moon’s South Pole. NASA simulations suggest that microbes such as Bacillus subtilis, Staphylococcus aureus, Deinococcus radiodurans, and the fungus Aspergillus niger could remain in a latent state within permanently shadowed regions like Nobile Rim and De Gerlache Rim for at least one terrestrial day.

While the lack of liquid water and atmosphere prevents these organisms from multiplying, their ability to endure extreme temperatures and ultraviolet radiation poses a risk of unintentional biological contamination. This persistence presents a challenge for planetary protection, as terrestrial biological traces could complicate the scientific search for primordial lunar chemical signatures and future life-detection missions.
