Looking Back - Sol 538 (Natural Colors - Credits: NASA)

This look back at a dune that NASA's Curiosity Mars rover drove across was taken by the rover's Mast Camera (MastCam) during the 538th Martian Day, or Sol, of Curiosity's work on Mars (Feb. 9, 2014). The Rover had driven over the dune three days earlier. For scale, the distance between the parallel wheel tracks is about 9 feet (i.e.: approx.
2,7 meters). The dune is about 3 feet (a little more than 1 meter) tall in the middle of its span across an opening called "Dingo Gap". This view is looking Eastward. This raw color image was recorded by the camera under Martian lighting conditions.
