OK, let's discuss this. The closest, supposedly reachable, celestial body which could yield mountains of information about outer space and NASA picks up, packs up, and decides to head to Mars instead. Really? Seems to me, corporately thinking of course, that the most cost effective study would be right here on our "reachable" moon. Huge craters that would yield many objects to study. These objects could then be continuously returned to earth for hands on physical analysis. Yet, where are all of these yields? Well, NASA prefers distant study and video....much more beneficial.
