Hi Sterling -
Short answer: Try a comet.
I am suspicious of the crater counts based on the Apollo samples data, as the
Moon is part of a two body system, the Moon and the Earth. It is very true that
the money for crater counting has been too low; even the money for
re-processing earlier planetary surface imagery has been too low. We do have
one data set right at hand, Earth craters, but guess what - the money for
studying them has been too low as well. The possible Shiva crater demonstrates
this all too well.
We need to know exactly what hit when. For the last 13,000 years or so, it has
been comet fragments. Whether this represents the long term trend I do not
know, but I believe Shoemaker may have had it right.
