Summary:
- NASA researchers have found that the lunar regolith, or soil, on the Moon is not a significant source of water for Earth. This is because the regolith contains very little water and is not able to efficiently transport water to Earth.
- The study shows that the water found on Earth is more likely to have come from other sources, such as asteroids or comets, rather than from the Moon's surface.
- This finding helps scientists better understand the origins of Earth's water and the role that the Moon has played in the formation and evolution of our planet.
