View Back Uphill After Entering 'Perseverance Valley'

A CLOSER LOOK

This image from the navigation camera (Navcam) on the mast of NASA's Mars Exploration Rover Opportunity provides a look back to the crest of Endeavour Crater's rim after the rover began descending "Perseverance Valley" on the rim's inner slope. The Navcam took this image on July 18, 2017, during the 4,793rd Martian day, or sol, of Opportunity's work on Mars. Wheel tracks from the top of the rim to the rover are visible above the rear solar panel of the vehicle. For scale, the distance between tracks from right-side wheels and tracks from left-side wheels is about 3.3 feet (1 meter). The knob-topped cylinder mounted at the edge of the solar panel is the calibration target for Opportunity's panoramic camera (Pancam). Opportunity's location on Sol 4793 was a site within the upper end of Perse
