How the Moon’s Hidden Protection Shields Against Solar Wind Erosion

It seems the Moon has been protecting itself from cosmic erosion all along! Using Apollo moon dust for the first time, a team of researchers found that the lunar surface’s rough, porous texture acts as a natural shield against solar wind bombardment, thus reducing erosion rates by up to ten times more than previously thought. This groundbreaking finding not only solves a long standing puzzle about the Moon’s thin atmosphere but also rewrites our understanding of how rocky planets lose material to space, with major implications for upcoming missions to the Moon and Mercury.
