NASA is going to "bomb" the moon to see if there is water hidden in it. For a long period of time, scientists thought there can't be any water on the moon. But recent studies have shown there might be billion of cubes of water on the moon, hidden deep in the moon craters.
"NASA is just hours away from punching two new craters in the moon, perhaps proving that water exists in the bottom of a crater at the moon's south pole."Source
We would know soon if there is water on the moon or not. Or if there is any, I wonder how it would taste like.
Don't worry, NASA won't blow up the moon...
