I have seen a number of articles about the lack of craters and the assumption that this means recent geological activity. But that would assume a similar craterization rate to that of the inner planets like Mars and our Moon. I am wondering, is it possible that due to it's orbit, distance and smaller size that the rate is just a lot slower? whatever, It is just a mind boggling accomplishment, and the photos really are incredible.
