Outstanding results for NASA 's search for water on moon

NASA's search for water on the moon has beaten expectations after a moonshot of a hole blasted in the moon last year reveals lots of water in a crater where the sun never shines - 41 gallons of ice and vapor.

That may not sound like much but it's almost twice as much as researchers had initially measured and more than they ever expected to find.

Mission chief scientist Anthony Colaprete of the NASA Ames Research Center calculates there could be 1 billion gallons of water in the crater that was hit enough to fill 1,500 Olympic-sized swimming pools. (AP)
