Original Caption Released with Image:

This image from NASA’s Mars Exploration Rover Spirit shows a daisy pattern created by the rover's rock abrasion tool on a rock dubbed "Mazatzal." The pattern was made as the rover brushed dust away from a large enough area of the surface of the wind-scalloped, volcanic rock to match the field of view of the rover's miniature thermal emission spectrometer. As Spirit ground into the surface with the diamond cutting teeth of the rock abrasion tool, a mineral-filled fracture in the rock suggested the possible presence of past water. The circles cut by the tool are about 5 centimeters (2 inches) in diameter.

Spirit acquired this image on Sol 86 (March 31, 2004) with the panoramic camera’s 753-nanometer, 535-nanometer, and 432-nanometer filters. The image is presented here in false color that is used to bring out subtle color differences.
