PIA07976: Close-up of 'Davis' on 'Jibsheet' Outcrop


Close-up of ‘Davis’ on ‘Jibsheet’ Outcrop

Caption:

This mosaic of four frames from the microscopic imager on NASA's Mars Exploration Rover Spirit shows the texture of a target called "Davis" on a rock outcrop called "Jibsheet" on "Husband Hill" inside Mars' Gusev Crater. The images were taken on Spirit's 487th martian day, or "sol (May 17, 2005). The individual frames are each 3 centimeters (1.2 inches) across and they overlap slightly in this two-by-two array. The glossier central region of the mosaic, about 4.5 centimeters (1.8 inches) in diameter, was scrubbed with the wire-bristle brush of Spirit's rock abrasion tool. 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. The image has been rotated 180 degrees
