An improved tool debuts Dec. 7 for viewing channels, dunes, boulders and other features revealed in the huge image files from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

The new tool, HiView, offers the best way to take a personal, virtual hike through any of thousands of square miles of Mars observed by HiRISE, seeing details as small as a desk. To watch the tutorial video and download the free HiView application, go to: http://www.uahirise.org/hiview/ .

The Mars Reconnaissance Orbiter has been studying Mars with an advanced set of instruments since 2006. It has returned more data about the planet than all other spacecraft combined. For more information about the mission, visit: http://www.nasa.gov/mro and http://mars.jpl.nasa.gov/mro .

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