According to a latest study led by a group of scientists from Brown University in US, a huge reservoirs of water may exist under the surface of the Moon. The gallons of water have been reserved in the form of volcanic 'glass beads' and will be used in future lunar colonies.
Earlier in 2008, another trace of some waters in volcanic glass beads have also been found by researchers.
In 2011, further study of tiny crystalline formations within those beads revealed that they actually contain similar amounts of water as some basalts on Earth, suggesting that the Moon's mantle contains as much water as Earth's.
Talking about the same Ralph Milliken, an associate professor at Brown University in the US has said, "The key question is whether those Apollo samples represent the bulk conditions of the lunar interior or instead represent unusual or perhaps anomalous water-rich regions within an otherwise 'dry' mantle."
"By looking at the orbital data, we can examine the large pyroclastic deposits on the Moon that were never sampled by the Apollo or Luna missions," he added.
"The fact that nearly all of them exhibit signatures of water suggests that the Apollo samples are not anomalous, so it may be that the bulk interior of the Moon is wet," Milliken further added.
Meanwhile, being asked about the future expectations and plannings, Shuai Li, a postdoctoral researcher at the University of Hawaii in the US has said, "Anything that helps save future lunar explorers from having to bring lots of water from home is a big step forward, and our results suggest a new alternative."
