MARS RECONNAISSANCE ORBITER HIRISE IMAGES February 4, 2015
o Tangential Craters within Ptolemaeus Crater http://hirise.lpl.arizona.edu/ESP_020065_1335 This image shows two small craters, just touching on their rims, in the much larger Ptolmaeus Crater. o Curiosity Rover at Pahrump Hills http://hirise.lpl.arizona.edu/ESP_039280_1755 The region contains sedimentary rocks that scientists believe formed in the presence of water. o Yardangs in Arsinoes Chaos http://hirise.lpl.arizona.edu/ESP_039563_1730 Yardangs are portions of rock that have been sand blasted into long, skinny ridges by bouncing sand particles blowing in the wind. o Icy Wonderland http://hirise.lpl.arizona.edu/ESP_039633_0950 The weak boundaries of the polygonal structure of the surface have been eroded by spring sublimation of carbon dioxide as energy from the Sun turns ice to gas. 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.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
