Our Moon Could Be Conveniently Full of Water

It’s been known for a while (especially since the 2009 LCROSS impact experiment) that there is water on the Moon. But so far the largest volume has been found as ice inside the shadowed walls of craters on the Moon’s south pole, likely originating from ancient comet impacts. Now, using data collected by India’s Chandrayaan-1 lunar satellite, researchers from Brown University in Providence, Rhode Island have identified water inside ancient pyroclastic flows located across the Moon’s surface—water that must have come from inside the Moon itself.

“We observe the water in deposits that are at the surface today, but these deposits are the result of magma that originally comes from deep within the lunar interior,” said Ralph Milliken, a geologist at Brown and lead author of the study. “Therefore, because the products of the magma have water, the deep interior of the Moon must also contain water.”

While the age and origin of this indigenous interior water aren’t yet known, its availability near the surface would be a valuable asset for any future human settlements on the Moon.
