The rock abrasion tool on NASA's Mars Exploration Rover Spirit ground two
holes in a relatively soft rock called "Wooly Patch" near the base of the
"Columbia Hills" inside Gusev Crater on Mars. This approximately
true-color image from the panoramic camera was taken on sol 200 (July 25,
2004) and generated using the camera's 600-, 530-, and 480-nanometer
filters. It shows the natural red and reddish-brown color of the rock.
Scientists speculate that this relatively soft rock (compared to others
analyzed by Spirit) may have been modified by water. Small cracks in the
surface outside the drill holes may be the result of interactions with
water-rich fluids.
