Aerial view of Perseverance Valley This orbital image of Perseverance Valley was taken by the HiRISE camera on the Mars Reconnaissance Orbiter. You can see the notch where the valley begins in the crater rim in lower left quadrant of image. Its branching pattern becomes apparent in the center of image. Opportunity and the MER mission are seeking to determine how this unique geologic feature in Endeavour Crater formed some 2 billion years ago. NASA / JPL-Caltech / University of Arizona
