 A lot of that was water and comets and so forth. So besides possibly getting some inkling of how life started on Earth by discovering what was coming in and where it came from, we may also find some additional water deposits, and that's sort of the holy grail that everybody's after on the Moon, especially down by the South Pole, is finding water there, because you can do a lot with it once you have it. Can we assume, though, Rod, that the backside of the Moon and the other side we see might be the same?
