It is an interesting idea for these reasons: 1. Mars' thinner atmosphere means more meteorites survive the fall though it than on Earth. 2. The surface is tens if not hundreds of millions of years older than any surface in northwest Africa or any dry lake bed. Thus, there is an enormous time for meteorites to accumulate on it not found on Earth. 3. Little, if any water, and very low temperatures mean that the weathering, which destroys meteorites on Earth, is almost nonexistent on that part of Mars. Thus, once a meteorite falls, it remains there for virtually forever. It is a reasonable hypothesis that there meteorites should be more abundant on parts of Mars than anywhere on Earth. does this mean some of out list members will be planning a trip there soon? :-) Yours, Paul Baton Rouge, LA __________________________________ Do you Yahoo!?
