MARS RECONNAISSANCE ORBITER HIRISE IMAGES March 25, 2011
o Light-Toned Layering in Noctis Labyrinthus Pit http://hirise.lpl.arizona.edu/ESP_019377_1695 Just like on Earth, rock layers can tell the geologic history of a region: it's a window to the past. o The Beautiful Arc of a Dune http://hirise.lpl.arizona.edu/ESP_019992_1340 In the full observation, we can see several dunes within a crater and a gorgeous dune that arcs to the center of the image. o Spring Drama http://hirise.lpl.arizona.edu/ESP_021522_0930 This region is also host to surface features with radially-organized channels carved in the surface by seasonal erosion by escaping carbon dioxide gas, known colloquially as "spiders." o Possible New Gully Activity http://hirise.lpl.arizona.edu/ESP_021622_1095 The dunes in this image, currently losing their winter coat of carbon dioxide frost, sport possibly active gullies on their southern edge. o Dunes and Dust Devils http://hirise.lpl.arizona.edu/ESP_021641_1205 In the Southern hemisphere we see fields of sand dunes on the floors of many craters. All of the HiRISE images are archived here: http://hirise.lpl.arizona.edu/ Information about the Mars Reconnaissance Orbiter is online at http://www.nasa.gov/mro. The mission is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, for the NASA Science Mission Directorate, Washington, D.C. Lockheed Martin Space Systems, of Denver, is the prime contractor and built the spacecraft. HiRISE is operated by the University of Arizona. Ball Aerospace and Technologies Corp., of Boulder, Colo., built the HiRISE instrument. ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
