Pits, Flows, Other Scenes in New Set of Mars Images
Thousands of new Mars images from 340 observations by the highest resolution camera orbiting the Red Planet include scenes of rimless pits, mud volcanoes and other features.
Newly  released images from 340 recent observations of Mars by the High Resolution  Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance  Orbiter show details of a wide assortment of Martian environments.Strewn  boulders and rippled sand lie on the floors of two shadowy, steep-walled pits.  Mounds in another region appear to be mud volcanoes, which may have brought  fine-grained material to the surface from deep underground. In the Tharsis  volcanic region, the intersection of a lava flow with a trough caused by ground  collapse allows seeing whether the flow happened before or after the collapse.These and  thousands of other images from HiRISE observations between Oct. 1 and Nov. 1,  2010, are now available on NASA's Planetary Data System (http://pds.jpl.nasa.gov/)  and the camera team's website (http://hirise.lpl.arizona.edu).The camera is  one of six instruments on NASA's Mars Reconnaissance Orbiter, which reached  Mars in 2006.  It has made more than  17,000 observations. Each observation covers an area of several square miles on  Mars and reveals details as small as desks.For more  information about the Mars Reconnaissance Orbiter mission, seehttp://mars.jpl.nasa.gov/mro/.
