How Much Water Ice is on the Moon?
Recent studies indicate that lunar soil contains about 6% water ice within the top 10 meters, primarily located in cold traps. This finding, derived from advanced radar and radio telescopes, suggests that while water ice exists, its usability for future missions remains uncertain.

What Are Cold Traps on the Moon?
Cold traps are areas on the moon that remain permanently shadowed and extremely cold, allowing water ice to accumulate without sublimating. These regions are of particular interest for future lunar missions, as they may serve as potential resources for astronauts.

What Are the Skepticisms Surrounding Lunar Water Ice?
Despite the promising findings, some experts express skepticism about the actual usability of lunar water ice. Alfred McEwen from Arizona State University questions the value of these resources, while others, like Clive Neal from the University of Notre Dame, suggest that more exploration is needed to determine the true extent of water ice on the moon.
