NASA's Curiosity Mars rover and its recent tracks from driving in Gale Crater appear in an image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Dec. 11, 2013.

Excerpts from the large HiRISE observation are at:

The tracks show where the rover has zigzagged around obstacles on its route toward the lower slopes of Mount Sharp, its next major destination.

HiRISE first imaged the Mars Science Laboratory spacecraft while it was descending on a parachute to place Curiosity on Mars 17 months ago. Since then, it has provided updated views of the rover's traverse, as seen from orbit.

HiRISE is operated by the University of Arizona, Tucson. The instrument was built by Ball Aerospace & Technologies Corp., Boulder, Colo. The Mars Reconnaissance Orbiter project and Mars Science Laboratory project are managed for NASA's Science Mission Directorate, Washington, by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena.
