The Sutter’s Mill meteorite fell to ground on 22 April 2012 and shortly thereafter searches were instigated for samples by NASA-ARC and SETI personnel in cooperation with multiple volunteers from the public. These efforts resulted in the finding of a number of metoeritic stones that were subsequently analyzed using a variety of analytical techniques by a world-wide consortium of scientists. The results of this work appeared as a Research Article in the 21 Dec 2012 issue of Science. These efforts established that the Sutter’s Mill meteorite is an unusual carbonaceous chondrite, a relatively rare type of meteorite that contains prebiotic organic compounds.
