MARS RECONNAISSANCE ORBITER HIRISE IMAGES
June 20, 2012

o Rough Surfaces in Deuteronilus Mensae	
  http://hirise.lpl.arizona.edu/ESP_025174_2245

  The objective of this observation is to examine what may be 
  formerly ice-rich terrain that has just lost ice to the atmosphere.

o Exploring Antoniadi Crater	
  http://hirise.lpl.arizona.edu/ESP_025331_2005

  Antoniadi Crater was identified, even prior to the MRO mission, as 
  a likely ancient lake (now dry) that was supplied by both surface 
  water and ground water.

o Ridges in Meridiani Planum

  When terrain gets squeezed by geologic forces deep rocks sometimes 
  break and get pushed upwards forming raised wrinkles on the surface.

o Colorful Layers in Nili Fossae

  This enhanced-color version of the central part of the HiRISE image 
  shows colorful layers that may contain carbonate minerals.
