Troy, the lighter disturbed soil near the center-right in this image, is part of an area called "Scamander Plains," which lies at the edge of a small filled-in crater near the Western edge of Homeplate. Spirit became embedded after the wheels cut through a darker top layer of soil. The composition of different layers in the soil at the site became the subject of intense investigation by tools on Spirit's robotic arm. For scale, the parallel rover tracks are about 1 meter (39 inches) apart. The track on the right is more evident because Spirit was driving backwards, dragging its right-front wheel, which no longer rotates.
Three versions of this view are offered at full resolution: an approximate true color rendering generated with Pancam's 601-nm, 535-nm, and 482-nm filters, a false-color, red-green-blue composite generated from Pancam's 753-nm, 535-nm, and 432-nm filters, and a harshly stretched version of the false color mosaic to bring out the subtle color changes in the scene.
Spirit has been investigating a region within Mars' Gusev Crater for more than 79 months in what was originally planned as a three-month mission.
