Hidden reserves of water found in Moon

Scientists have found a mineral in a lunar meteorite pointing to the presence of abundant hidden reserves of water ice under the surface of the Moon.
A team from the Tohoku University in Japan found the mineral, called moganite, in a lunar meteorite discovered in a desert in northwest Africa. Moganite, a crystal of silicon dioxide, is known to form on Earth in specific circumstances in sedimentary settings from alkaline fluids. It has never before been detected in samples of lunar rock. Researchers believe the mineral formed on the surface of the Moon in the area called Procellarum Terrane, as water originally present in lunar dirt evaporated due to exposure to strong sunlight.”For the first time, we can prove that there is water ice in the lunar material,” said Masahiro Kayama from Tohoku University, who led the study.
“In a moganite, there is less water, because moganite forms from the evaporation of water. That’s the case on the surface of the Moon. But in the subsurface, much water remains as ice, because it’s protected from the sunlight,” Kayama told ‘Space.com’. For example, NASA’s Lunar Crater Observation and Sensing Satellite detected a shadowed crater near the Moon’s south pole. India’s probe Chandrayaan-1 recorded evidence of water in the thin atmosphere above the Moon’s surface.
