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.
