Birthplace of famous Mars meteorite pinpointedhttp://www.newscientist.com/article.ns?id=dn8004--- "There was only this one place, in all the places we can look that aren't too dusty, that had a composition that was consistent with the ALH84001." ---
The site is in the Eos Chasma and there is a crater about 20 kilometers in diameter.
