'Moon even has its own water cycle'

[1]

Washington: A year after announcing the discovery of water molecules on the moon, NASA scientists have now said the earth's satellite is not only rich in useful materials, it has a water cycle of its own.

In fact, new studies suggest that there is a lot more water on the moon than earlier thought.

The new data uncovered by NASA's Lunar Crater Observation and Sensing Satellite, or LCROSS, and Lunar Reconnaissance Orbiter, or LRO found evidence that the lunar soil within shadowy craters is rich in useful materials, and the moon is chemically active and has a water cycle.
