        This mosaic was acquired by the Mars Exploration Rover Spirit on Sol 2019 (September 7, 2009). This bittersweet image shows the area directly in front of the rover's left front wheel. The bright disturbed soil was a key source of information about the story of water at Gusev Crater, as well as the reason Spirit would ultimately never leave this spot. The rover became embedded in this soil and could not achieve enough tilt to survive the winter. Pancam's 601nm, 535nm, and 482nm filters were used in this vertical projection mosaic.  Three versions are available below at full resolution: an approximate true color rendering, a false color stretch to enhance the subtle color differences in the scene, and a stereo anaglyph for 3D viewing with red blue glasses.
