MARS RECONNAISSANCE ORBITER HIRISE IMAGES
April 2, 2014

o Ring of Cratered Cones

  Interestingly, the area around the ring has few cones: did water 
  or steam flow to the crater and make that zone less fertile?

o Mission 2020: A Candidate Landing Site in Gusev Crater	
  http://hirise.lpl.arizona.edu/ESP_035164_1655

  As we did for Phoenix in 2008 and the Mars Science Laboratory in 
  2012, HiRISE has been imaging landing sites for a potential rover 
  mission in 2020.

o An Irregular Crater Intersecting Graben in Tractus Albus	
  http://hirise.lpl.arizona.edu/ESP_035226_2090

  This crater is very irregularly shaped and might suggest that some 
  underlying liquid was present that made it so elongated after the 
  initial impact.

o An Elevated Crater in the Apollinaris Mons Region: Volcanic or Impact-Related?	
  http://hirise.lpl.arizona.edu/ESP_035863_1710
  
  When a circular depression is visible on the summit of a mound or 
  elevated landform, careful analysis is needed to identify if it was 
  created by an impact or by volcanic activity.

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.
