This is the meteorite causing all of the excitement about life possibly existing on Mars. This meteorite was the first meteorite found by the Antarctic team in 1984. The meteorite was initially identified as a diogenite, a rare type of achrondite meteorite. It wasn't until October 1993 that David Mittlefehldt caught the error, and properly identified as as an SNC.
