This 360-degree view combines frames taken by the navigation camera on NASA's Mars Exploration Rover Spirit during the rover's 271st martian day, or sol, on Oct. 7, 2004. The rover had just driven into position for using the tools on its robotic arm (not in the picture) to examine a layered rock called "Tetl" in the "Columbia Hills." Spirit's total driving distance from its landing to this point was 3,641 meters (2.26 miles), more than six times the distance set as a criterion for mission success. The view presented here in a vertical projection with geometric seam correction.
