The moon’s surface contains stored water, according to three different space probes gathering evidence. Although many scientists have thought that ice might be trapped in the moon’s colder, shadowed craters, this newer evidence shows that water actually exists on the sunlit surface. The amount is still very small and very different from water as we know it. In fact, it’s not liquid water, frozen water or gaseous water, which we’ve been trained since second grade to believe are the only forms water can take. Instead, this water is a thin film of molecules. Scientists estimate that scraping molecules from an area the size of a football field would only produce less than a quart of water.
