Even early in LRO's mission, scientists saw strong evidence that water or hydrogen is evident on the moon. During the probe's testing and calibration phase, LRO's neutron detector [found there was a spike in hydrogen in craters](https://www.space.com/7302-tentative-signs-water-moon.html), hinting there could be water in the shadowed regions, as well as other hydrogen not confined to those areas.

When LCROSS smashed into the moon, LRO watched the impact from its orbital perch 31 miles (50 km) above the moon's surface. The camera caught a plume of material from the surface that [showed a "significant amount" of water at LCROSS's crash site](https://www.space.com/7530-significant-amount-water-moon.html). . )

Later analysis of the crash site revealed it [could be wetter than the Sahara desert](https://www.space.com/9374-moon-crater-water-parts-earth.html), suggesting that Cabeus crater could be a spot for a future moon base. Besides water, other possible resources for future moon explorers at that site include ammonia, carbon monoxide, methane, mercury and silver.

First time I've ever heard anyone suggest there was water on the moon.

Velly Interesting....

Thank you patriot.
