The NASA scientists spot water molecules moving around the day side of the Moon,using Lunar Reconnaissance Orbiter(LRO).
NASA observes this as a good sign to carry out future lunar missions using the water presence in moon.
Measurements from the Lyman Alpha Mapping Project (LAMP) instrument abroad the LRO of the sparse layer of molecules temporarily stuck to the surface helped characterise lunar hydration changes over the course of a day,according to the study published in the journal of Geophysical Research Letters.
More recently,scientists have identified surface water in sparse populations of molecules bound to the soil,or regolith,NASA said in a statement.This water which remains tightly bound to the regolith until the temperatures peak near lunar noon is common at higher altitudes in moon.
Michael Poston from Southwest Research Institute(SwRI) in Texas,US had previously conducted extensive experiments with water and lunar samples collected by the Apollo mission and revealed the amount of energy needed to remove water molecules from lunar materials,helping scientist understand how water is bound to surface materials.
“Previous research reported quantities of hopping water molecules that were too large to explain with known physical processes.I’m excited about these latest results because the amount of water interpreted here is consistent with what lab measurements indicate is possible,”he said.They found that water builds up over time,rather than raining down directly from solar wind.
