MARS RECONNAISSANCE ORBITER HIRISE IMAGES
December 14, 2011

o Fresh Crater North of Tharsis Region
  http://hirise.lpl.arizona.edu/ESP_019641_2310

  The ejecta blanket---remnants of the material from the original
  impact--- is still visible indicating that the crater may be very fresh.

o Layering in Central Candor Chasma
  http://hirise.lpl.arizona.edu/ESP_019732_1750
  
  This area also has a high abundance of hematite, a mineral that can
  precipitate out of water.

o Spring Fans Bursting from Cracks in Ice
  http://hirise.lpl.arizona.edu/ESP_024428_2605

  In the springtime the ice on the dunes in the North polar region
  cracks, often in polygonal patterns.

o Faults in Ius Chasma
  http://hirise.lpl.arizona.edu/ESP_025020_1720

  Ius Chasma is one of many steep-sided interconnected depressions that
  comprise Valles Marines, the largest canyon system in the Solar System.
