If you're interested in citizen science projects. A site called CosmoQuest run by the Fraser Cain of The Universe Today and Dr Pamela Gay of Astronomy Cast has a project up marking moon craters in images taken by NASA's Lunar Reconnaissance Orbiter. The want to get a million craters marked before the 5th of May. That may be overly hopeful as the count is only about 70k at the moment.

It's incredible how many craters there are on the moon. They're endless. I've tried the planetary transits from kepler on Zooniverse. Moon craters are somewhat easier. I think zooniverse do a moon crater thing too. At cosmoquest with the forums and google hangouts they do you feel closer to the people running the place.
