Hi all - I'm setting something of a personal record here today - we all get enough messages, and I have to remember that not everything requires my personal comment, but in this case, here goes -
IF only NASA would provide us with some decent new crater counts from the moons of Jupiter and Saturn, it would save us from a lot of theory and computer models. The differentation in irons these folks are seeing may have come from only one proto-planet whose accretion suddenly stopped, say 3.8 billion years ago. In closing, we still don't have a unified accretion model which accounts for all of the craters. Good hunting - EP --- "Sterling K.
