Original Caption Released with Image:

This mosaic of 24 frames from the microscopic imager on NASA's Mars Exploration Rover Spirit shows the texture of a target called "Keystone" on the "Methuselah" outcrop of layered rock on "Husband Hill" inside Mars' Gusev Crater. The images were taken on Spirit's 469th martian day, or "sol (April 28, 2005). The target area shows fine layers that may have been deposited by wind or water. The individual frames are each 3 centimeters (1.2 inches) across and they overlap slightly in this array of six frames horizontally by four frames vertically. The target was fully shadowed when the images were acquired. The scale of the images (31 microns or one one-thousandth of an inch per pixel) allows features as small as 0.1 millimeter (four one-thousandths of an inch) to be resolved.
