"Perseverance Valley" lies just on the other side of the dip in the crater rim visible in the left half of this 360-degree panorama from the Navigation Camera (Navcam) on NASA's Mars Exploration Rover Opportunity.
As the rover arrived at this area in early May 2017, researchers began looking for clues about what process carved the valley. The rover team plans to drive Opportunity all the way down the valley into the interior of Endeavour Crater.
The foreground and the area to the right are on the plain just outside of Endeavour Crater. An orbital view of the location is at PIA21496.
The high point near the center of the image is called "Winnemucca," part of an Endeavour rim segment called "Cape Byron." Endeavour's interior and distant eastern rim are visible at upper left, above the notched portion of the western rim that sits directly above Perseverance Valley.
The rover's Navcam took the component images of this scene on May 2 and May 3, 2017, during the 4,718th and 4,719th Martian days, or sols, of Opportunity's work on Mars, two days before a drive that brought Opportunity to the head of the valley.
