MARS RECONNAISSANCE ORBITER HIRISE IMAGES November 7, 2012
o Topography of Moving Dunes in Nili Patera http://hirise.lpl.arizona.edu/ESP_017762_1890 Many HiRISE targets are imaged twice, close together in time, with each image having a different viewing angle, allowing us to create a digital elevation model, or DEM. o The First Day of Southern Spring http://hirise.lpl.arizona.edu/ESP_028956_0930 Like the Earth, Mars is tilted on its axis, and the sun crosses the equator twice each year. On Earth we call this the equinox. o A New Impact Site http://hirise.lpl.arizona.edu/ESP_029015_1705 What's unusual about this site is that it isn't as dusty as most places where new impacts are discovered. o Compositionally Diverse Bedrock http://hirise.lpl.arizona.edu/ESP_029234_2015 Regolith, particulate fragmented rock and fine grained soils, generally covers most of the surface of Mars. 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 http://six.pairlist.net/mailman/listinfo/meteorite-list
