"Lots" of water was found by NASA yesterday as solid ice under the surface.
Scientists have long suspected that water was under the surface of the moon as ice. These rumors were increased by the Chandrayaan-1 spotted what seemed like ice when it was orbiting the moon. NASA confirmed this when they slammed two satellites into the moon on purpose. These satellites then tested for water and the test came out positive. There is apparently an equivalent of 24 gallon of water that was kicked up by the crash itself. There could actually be much more.
This a history-making day in space science. Now NASA is thinking about setting out a permanent base on the moon which it can use as a refueling stop on the way to Mars. Even Google put a image of the moon on their homepage to represent this historic event.
I think this is a very important day in space science and it may even be one of the greatest discoveries made by NASA.
