NASA - National Aeronautics and Space AdministrationMoffett Field, CA – Scientists found treasure when they studied a meteorite that was recovered April 22nd, 2012 at Sutter’s Mill, the gold discovery site that led to the 1849 California Gold Rush. Detection of the falling meteorites by Doppler weather radar allowed for rapid recovery so that scientists could study for the first time a primitive meteorite with little exposure to the elements, providing the most pristine look yet at the surface of primitive asteroids.

An international team of 70 researchers reported in an issue of “Science” that this meteorite was classified as a Carbonaceous-Mighei or CM-type carbonaceous chondrite and that they were able to identify for the first time the source region of these meteorites.

Fragments of the Sutter’s Mill meteorite fall collected by NASA Ames and SETI Institute meteor astronomer Dr. Peter Jenniskens in the evening of Tuesday April 24th, two days after the fall. This was the second recovered find. (Image credit: NASA / Eric James)
