Scientists Have Discovered That There is Water Under the Moon’s Surface – Futurism

In Brief New research from Brown University suggests that huge amounts of water may be found under the surface of the Moon. The presence of water in the Moon's mantle could provide insight to how water got to Earth and help sustain future deep space missions. A Wet Mantle

Scientists have long speculated about the presence of water on the Moon. Previous studies found traces of water in the icy shadowed regions of the Moons poles, but a recent study from Brown University suggests that there may be substantial amounts of water hiding inside the lunar rock.

Unlike the water in the lunar poles, which could have been caused byhydrogen coming from solar winds, the water in the mantle came very early in theMoonsformation, Brown University geologist Ralph Milliken said in an interview withSpace.com. In their study published in the journal Nature Geoscience, Milliken and his team examined pyroclastic deposits rock layers which were probably formed from large volcanic eruptions using satellite data from the Moon Mineralogy Mapper instrument on the Indian Chandrayaan-1 probe.

Our work shows that nearly all of the large pyroclastic deposits also contain water, so this seems to be a common characteristic of magmas that come from the deep lunar interior, Milliken said in the interview. That is, most of the mantle of the moon may be wet.'

How large amounts of water ended up under the Moons surface remains unclear. Understanding it the water got there, possibly delivered after the giant impact event, as Millikens team thinks, could help explain how water came to be on Earth.

Even more interesting is the potential help lunar water could give to future exploration on the Moon and beyond. These deposits may be much easier to access than potential water ice in shadowed regions at the lunar poles, Milliken added in the interview. Water is heavy and expensive to take from Earth to space, so any bit of water that you can get on the moon instead of bringing with you from Earth is a big deal and opens up possibilities for sustained human presence on the moon.

This would be especially useful since some Mars missions in the works right now notably NASAs involve using the Moon as a jump off point. A potential lunar base would be easier to maintain given the presence of water on Earths satellite.

The better we understand how much water is there, then the better we can estimate the processes responsible and the usefulness of the deposits for future human exploration, Milliken said to Space.com.
