月球上有水， 不是流动水

Yes, there is water on the Moon, but not in liquid lakes; it exists as ice in permanently shadowed polar craters and as water molecules trapped in minerals across the sunlit surface, making it far more widespread than previously thought. This water, found in low concentrations (like a few drops in a 12-ounce bottle of water per cubic meter), is crucial for future space exploration, says NASA, and is chemically bound or in icy chunks mixed with lunar soil.
