Could somebody take a look at this microscopic imager view from Spirit, just posted, and tell me if you think it's just scrapes from the abrasion tool, or something more interesting -- like fossils. http://marsrovers.jpl.nasa.gov/gallery/all/2/m/099/2M135153386EFF2700P2959M2... Does anyone know where to find information on the image? I would like to know what terrain the picture is in (solid rock, soil, etc.), the scale of the image (microns, mm, meters), and lighting (natural, artificial, high/low angle, etc.). Pictures of rock/soil with no scales are difficult to interpret for processes that create structure. Without image info, it could be a photomicrograph of an rock, or a picture of a planet surface from orbit. The scale invariance of geology is always fun. :)
