A study published in Science Advances on August 19, 2026, suggests that microbes hitching a ride with future Artemis astronauts could potentially survive in the shadowed regions of the Moon's south pole.[^1]

Simulations of the Nobile Rim, Connecting Ridge, and De Gerlache Rim revealed that even an astronaut's footprint could become a habitable zone for microbes.[^2] The researchers tested five common human skin and spacecraft microorganisms, including the fungus Aspergillus niger, to determine their tolerance to heat and ultraviolet radiation.[^5]

The study utilized detailed environmental maps built from elevation and temperature data collected by instruments on NASA's Lunar Reconnaissance Orbiter combined with radiation models.[^3] A similar warning was issued in a NASA study published on April 12, 2026, which noted that human microbes traveling with astronauts could survive in the permanently shadowed regions of the Moon's South Pole.[^4]
