NASA Study Finds Earth Microbes Could Survive on the Moon
What Happened
A NASA-led study found that some bacteria and fungi carried by astronauts could survive in cold, permanently shadowed regions near the Moon’s South Pole. Researchers identified sheltered areas where certain microbes could persist for days, weeks, or even longer in a dormant state, challenging the assumption that the Moon is completely hostile to Earth life.
Key Takeaways
The discovery raises concerns about contaminating future lunar and Mars missions, as Earth microbes could interfere with efforts to study pristine lunar chemistry or search for signs of extraterrestrial life. It also highlights the need for stricter planetary-protection measures as human exploration expands.
