NASA Researchers Think (Microbial) Life Could Survive on the Moon

In less than two years, NASA plans to have astronauts walking on the moon again — the first time in over half a century. "And one potential surprise could be detecting life on the moon," reports Space.com: New research suggests that future visitors to the lunar south pole region should be on the lookout for evidence of life in super-cold permanently shadowed craters — organisms that could have made the trek from Earth. Microbial life could potentially survive in the harsh conditions near the lunar south pole, suggested Prabal Saxena, a planetary researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "One of the most striking things our team has found is that, given recent research on the ranges in which certain microbial life can survive, there may be potentially habitable niches for such life in relatively protected areas on some airless bodies," Saxena told Space.com. Indeed, the lunar south pole may possess the properties that can enable survival and potentially even episodic growth of certain microbial life, Saxena said. "We're currently working on understanding which specific organisms may be most suited for surviving in such regions and what areas of the lunar polar regions, including places of interest relevant to exploration, may be most amenable to supporting life," he said. In work presented at a recent science workshop on the potential Artemis 3 landing sites, Saxena and study members reported that the lunar south pole may contain substantial surface niches that could be potentially habitable for a number of microorganisms. While it's possible organic molecules from earth might have been hurled to the moon after a meteor impact, there's a much more likely possibility. A NASA organic geochemist on the study views humans as "the most likely vector, given the extensive data that we have about our history of exploration..." Especially if humans start visiting these temperate radiation-protected sites...
