Fragment of the Nakhla meteorite that fell to Earth in 1911. American Museum of Natural History, August 2006

This meteorite is one of the SNCs, or "snicks", a class of meteorite that has one very interesting thing in common - they are all from Mars. This wasn't the first time I have seen a chunk of Mars, that honor goes to a fragment of ALH84001 in Washington D.C. (which I'll post a photo of eventually), but it is always thrilling to be just a few inches from a piece of another planet.
