Discovery Ridge and Sand Ripples

This mosaic of images from the Navigation Camera (Navcam) on NASA's Mars rover Curiosity shows the scene from the rover's position on the 376th Martian day, or sol, of the mission (August 27, 2013). The images were taken right after Curiosity completed the first drive during which it used autonomous navigation on unknown ground.

The view is centered toward the southwest and spans from east, at left, to north, at right. The prominent rock pile in the middle distance, left of center, is called "Discovery Ridge." The largest rocks in that pile are about 1 foot (0.3 meter) across. About 26 feet (8 meters) to the right of Discovery Ridge is a ripple of wind-deposited material. The ripple is about 13 feet (4 meters) long and begins about 33 feet (10 meters) from the rover.

The mosaic is presented as a cylindrical projection.
