Both the rovers, Spirit and Opportunity have passed the one Martian year mark on the Red Planet now. http://marsrovers.jpl.nasa.gov/home/index.html
The image was created using a photorealistic model of the rover overlaying a mosaic from the rover itself. Opportunity captured the underlying view of "Burns Cliff" after driving right to the base of this southeastern portion of the inner wall of "Endurance Crater." The view combines frames taken by Opportunity's panoramic camera between the rover's 287th and 294th martian days (Nov. 13 to 20, 2004).
This synthetic image of the Spirit Mars Exploration Rover on top of a rock called "Jibsheet" was produced using "Virtual Presence in Space" technology. Developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif., this technology combines visualization and image-processing tools with Hollywood-style special effects. The image was created using a photorealistic model of the rover and a false-color mosaic. The size of the rover in the image is approximately correct and was based on the size of the rover tracks in the mosaic. The mosaic was assembled from frames taken by the panoramic camera on the rover's 489th Martian day, or sol (May 19, 2005)
