Enhanced Color Panorama Above 'Perseverance Valley' on Mars


Toward the right side of this enhanced-color scene is a broad notch in the crest of the western rim of Endeavour Crater on Mars. Wheel tracks in that area were left by NASA's Mars Exploration Rover Opportunity as it observed "Perseverance Valley" from above in the spring of 2017. via NASA http://ift.tt/2uhwo7D
