This cylindrical-projection mosaic was assembled from images taken by the navigation camera on the Mars Exploration Rover Spirit on sol 107 (April 21, 2004) at a region dubbed "site 32." Spirit is sitting east of "Missoula Crater," no longer in the crater's ejecta field, but on outer plains. Since landing, Spirit has traveled almost exclusively over ejecta fields. This new landscape looks different with fewer angular rocks and more rounded, vesicle-filled rocks. Spirit will continue another 1,900 meters (1.18 miles) along this terrain before reaching the western base of the "Columbia Hills."
