NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this 360-degree view of the rover's surroundings on the 399th martian day, or sol, of its surface mission (March 8, 2005). Opportunity drove 35 meters (115 feet) that sol and reached the edge of "Vostok Crater" before taking the images. Sand has buried much of the crater. This location is catalogued as Opportunity's site 50. The view is presented in a vertical projection with geometric seam correction.
