The Opportunity rover has come across an odd-shaped, large, dark rock, about 0.6 meters (2 feet) across on the
surface of Mars, which may be a meteorite. The rover team spotted the rock called "Block Island," on July 18, 2009, in the opposite direction from which it was driving. The team then had the rover do a hard right (not really, but you know what I mean) and backtrack some 250 meters (820 feet) to study it closer. Oppy has been studying the rock with its
alpha particle X-ray spectrometer to get composition measurements and to confirm if indeed it is a meteorite.
Below, see a close-up, colorized version of Block Island and a 3-D version, both created by Photoshopper Extraordinaire Stu Atkinson.
