Because they're pretty sure there's some water underneath the surface, NASA is sending an old spacecraft crashing into the southern pole of the moon tomorrow morning. A small satellite will then search the plume of soil it kicks up for signs of ice, before it, too, crashes into the moon. "This is going to be pretty cool," says the mission's excited project manager, Dan Andrews, probably referring to smashing huge things into the moon under the guise of science. [AP via ABC News]
