This three-dimensional, cylindrical-perspective projection was constructed from images taken by the Mars Exploration Rover Opportunity's navigation camera on the rover's 93rd sol on Mars. The camera acquired the images at approximately 12:27 Local Solar Time, or around 8:22 AM Pacific Daylight Time on April 28, 2004. On that sol, Opportunity sat about 75 meters (246 feet) away from the rim of "Endurance Crater."
