Humphrey   << back to mosaics


        This mosaic was acquired by the Mars Exploration Rover Spirit on Sol 060 (March 4, 2004). This view shows the Rock Abrasion Tool (RAT) hole cut into the side of an upright rock named "Humphrey." The hole itself was named "Heyworth2." The mosaic covers roughly 30 degrees from top to bottom, while the RAT hole is about 4.5 cm (1.8 in) in diameter.  Pancam's 753nm, 535nm, and 482nm filters were used in this mosaic.  Two versions are available below at full resolution: an approximate true color rendering, and a false color stretch to enhance the subtle color differences in the scene.
