The two donut-shaped tracks make an infinity symbol, and mark the first two drives of NASA's Curiosity rover. The landing site is at the far right. Tracks from the first drive on Aug. 22, 2012 lead away from the landing site and include the donut at right. The second donut was made during the rover's second drive on Aug. 27.
The full-resolution images making up this mosaic were taken by the rover's Navigation camera.
JPL manages the Mars Science Laboratory/Curiosity for NASA's Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL, a division of the California Institute of Technology in Pasadena.
