NASA Orbiter Finds New Gully Channel on Mars

Standard

A comparison of images taken by the High Resolution Imaging
Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter in November 2010 and May 2013 reveal the formation of a new gully channel on a crater-wall slope in the southern highlands of Mars.

These before-and-after images are available online at http://www.nasa.gov/jpl/new-gully-channel-terra-sirenum-pia17958 .

Gully or ravine landforms are common on Mars, particularly in the southern highlands. This pair of images shows that material flowing down from an alcove at the head of a gully broke out of an older route and eroded a new channel.

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 is managed for NASA’s Science Mission Directorate, Washington, by NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena.
