Earth Microbes Could Survive in Moon's South Pole, NASA Study Finds
A NASA study published in August 2026 in Science Advances has found that some of the microbes humans carry with them to space may be capable of surviving in the harsh environment of the Moon's South Pole. Researchers examined how Earth-based microorganisms might persist in the permanently shadowed regions of this area, which represent some of the coldest and most inhospitable locations in our solar system.
The findings carry implications for lunar exploration efforts, particularly as NASA's Artemis program and other missions aim to establish a sustained human presence near the lunar south pole. Understanding whether terrestrial microbes can survive—and potentially contaminate—these areas is critical for planetary protection protocols and scientific integrity.
Scientists note that while the Moon's surface is generally hostile to life due to extreme radiation, lack of atmosphere, and temperature extremes, certain sheltered nooks and crannies could provide conditions marginally more hospitable. The study emphasizes the need for continued research into microbial persistence beyond Earth to inform future exploration strategies.
