Rock hunters bag five Mars meteorites CNN

Exploring the coldest and hottest places on Earth, space rock hunters have found five new meteorites from Mars, bringing the number of known stones from the red planet to 24. Planet scientists express keen interest in rare martian meteorites, some of which have offered tantalizing clues about whether the planet once possessed oceans or life. The recent cache actually includes six specimens, but two are presumed to be chunks from the same meteorite. One of the pair weighs in at 30 pounds (13.7 kg), the second-largest Mars meteorite fragment ever recovered, NASA scientists said this week.
