Microscopic shots starting to come in of that weird rock by Opportunity
Here.
Note the little seam of shiny stuff glaring at the camera.
I would like, once more, to express my immense appreciation for the way the Rover website has set up and organized its raw image files. This is great. Wish the Saturn shots were this well organized, but to be fair, the data stream for Cassini is not broken up as neatly into "sols" as the rover data is.
