Moon has Water and its own Water Cycle, says NASA

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.

Scientists also confirmed the water was in the form of mostly pure ice crystals in some places. The results are featured in six papers published in the October 22 issue of Science.

"NASA has convincingly confirmed the presence of water ice and characterised its patchy distribution in permanently shadowed regions of the moon," said Michael Wargo, chief lunar scientist at NASA Headquarters in Washington.
