Scientists have observed any water molecules moving around the day side of the Moon, using an instrument NASA's Lunar Reconnaissance Orbiter (LRO).
Scientists thought that the Moon was very dry until the last decade or so and water existing there mainly as pockets of ice in permanently shaded craters near the poles. But more recently, scientists have identified surface water in sparse populations of molecules bound to the lunar soil or regolith (loose rock).
The amount of the water molecules and locations vary based on the time of day in the Moon. This water is more common at higher latitudes and tends to hop/rise around as the surface heats up until temperatures drop and the molecules return to the surface. Scientists recently converted the (Lyman Alpha Mapping Project) LAMP’s light collection mode to measure reflected signals on the lunar dayside with more precision which allowing us to track more accurately where the water is and how much is present.
Again Scientists have hypothesized that hydrogen ions present in the solar wind may be the source of most of the Moon’s surface water.
However, if the lunar–water is present indeed, it can potentially be used by humans to make fuel or to use for radiation shielding or thermal management.
