Scientists have analyzed data from the Mini-SAR radar on India's Chandrayaan-1 spacecraft to discover nearly 600 million tons of water ice locked in permanently shadowed craters near the moon's north pole.

Lunar water is a resource of inestimable value. Reserves of this volume would be enough to support a permanent colony on the moon and could even be used as fuel for missions to Mars, the asteroids, and beyond.  Water is the key to the exploration and exploitation of natural resources in space.  Finding this much water on the moon is unbelievably great!
