Martian landforms<\/span> shaped by winds, water, lava flow, seasonal icing and other forces are analyzed in 21 journal reports based on data from a camera orbiting Mars. <\/span><\/div>
<\/div>

The research in a January special issue of Icarus testifies to the diversity of the planet <\/span>being examined by the High Resolution Imaging Science Experiment<\/span> (HiRISE<\/span>) camera on NASA<\/a>'s Mars Reconnaissance Orbiter<\/span>. Examples of the findings include: <\/span><\/p>

<\/div>

-- Valleys associated with light-toned layered deposits in several locations along the plateaus adjacent to the largest canyon system on Mars <\/span>suggest low-temperature alteration of volcanic rocks by acidic water both before and after formation of the canyons. <\/span><\/p>

<\/div>

-- The youngest flood-lava flow on Mars, found in the Elysium Planitia region and covering an area the size of Oregon, is the product of a single eruption and was put in place turbulently over a span of several weeks at most. <\/span><\/p>

<\/div>

-- New details are observed in how seasonal vanishing of carbon-dioxide ice sheets in far-southern latitudes imprints the ground with fan-shaped and spider-shaped patterns via venting of carbon-dioxide gas from the undersurface of the ice. <\/span><\/p>

<\/div>

HiRISE <\/span>is operated by the University of Arizona, Tucson, and was built by Ball Aerospace & Technologies <\/span>Corp., Boulder, Colo. It is one of six instruments on NASA's Mars Reconnaissance Orbiter<\/span>, which is managed by NASA's Jet Propulsion Laboratory<\/span>, Pasadena, Calif., and was built by Lockheed Martin Space Systems, Denver. The U.S. Geological Survey Astrogeology Science Center<\/span>, Flagstaff, Ariz., played a special role in preparation of the special issue, providing two guest editors and authorship of multiple papers.
