Tomorrow, NASA is going to send three objects (apparently 3 stages of a rocket) crashing into a crater on the moon to look for signs of water. Current projections are for an impact of 4:30 a.m. PDT. To see what they are aiming for, take a look at this picture from the Astronomy Photo of the Day. Thanks to my Dad for the tip - he keeps me up-to-date on all the cool photos posted on the APOD website!
Just in case you happen to be up at that hour, you can check it out on NASA TV (or I'm sure see replays later).
Any guesses as to whether or not it has water? My (totally unscientific) guess is that they will find water.
