The Mystery of Water on the Moon

SMRTR summary

New research using 17 years of Lunar Reconnaissance Orbiter data reveals the moon's water has been accumulating slowly over 3 to 3.5 billion years, with the oldest craters containing the most ice. Computer simulations show water concentrated in permanently shadowed polar regions, likely deposited through volcanic activity or solar wind interactions rather than comet impact. These polar ice reserves could prove crucial for future lunar missions, potentially providing drinking water, oxygen, and rocket fuel for humanity's long-term lunar presence.
