This view was assembled from images taken by the navigation camera on NASA's Mars Exploration Rover Spirit during the rover's 337th martian day, or sol (Dec. 14, 2004). Spirit's position, catalogued as Site 100 for the mission, was on the slope of "Husband Hill." The rover had driven 6 meters (20 feet) on Sol 337 after examining a rock called "Wishstone" for several sols. That rock is just to the left of the top of the arch traced by the rover tracks in this view. Spirit experienced slippage of up to 80 percent on uphill portions of the day's drive. The view is presented here in a cylindrical projection with geometric seam correction.
