Can you direct me to the info showing the return data matching the shergottites? I was not aware of this (I have a young family and full time job, I cannot read it all). That, to me is fascinating evidence I was not aware of. My understanding was that SNC probably sample only two of sites on mars (ALHA84001 a third). This being the case, you wouldn't necessarily expect our rovers to return pics like SNC Odd only one meteorite from the ancient half of mars (84001) so far. Is there an explanation for this? Is it just luck of the draw? The two most recent imacts (producing all SNC) have both been from the newer side of Mars? How much does one theory influence the other?
