Scientists suggest that permanently shadowed regions (PSRs) on the moon could harbor dormant microbes, potentially affecting future lunar research. These regions, located near the moon's poles, remain dark and cold due to their unique positioning, making them a potential refuge for bacteria like Bacillus subtilis. This species, commonly found on Earth and known for its resilience, could survive in PSRs after being introduced via spacecraft. Understanding the presence and impact of these microbes is crucial for future explorations, particularly for sample analysis from these sites.
'The question then is to what extent does this contamination matter? This will depend on the scientific work being done within the PSRs.'
'That analysis will be easier if contamination from terrestrial sources is minimized,' Moores added, highlighting the potential challenges in future lunar studies.'
