Upper edge of Perseverance Valley As Opportunity pulled up to Perseverance Valley in May 2017, she used her Pancam to
shoot this image. It shows the upper edge of Endeavour Crater’s rim and the ‘spillway’
leading into the valley, which falls downslope to the left for the length of two American
football fields or about 219.45 meters or 240 yards. Under the direction of Planetary
Society President Jim Bell, the Pancam science lead, this image was processed at ASU
in false color, a technique that enables scientists to better discern the various geological
features in the scene. NASA / JPL-Caltech / Cornell / ASU
