MARS RECONNAISSANCE ORBITER HIRISE IMAGES
August 21, 2013

o Small Crater within Pollack Crater Containing Light-Toned Material
  http://hirise.lpl.arizona.edu/ESP_018212_1715

  This observation shows a small crater in within the much larger
  Pollack Crater containing light-toned material.

o Lava Against an Impact Crater in Elysium Planitia
  http://hirise.lpl.arizona.edu/ESP_018537_1860

  In places where we see smaller ridges in the lava, they have steep
  faces that retain less dust and look rocky.

o Looking for Changes in Dust Drifts West of Alba Mons
  http://hirise.lpl.arizona.edu/ESP_032709_2210

  This image was intended to search for surface changes after three Mars
  years in a dust-covered region west of the Alba Mons volcano.

o Frosted Impact Crater in Late Northern Winter
  http://hirise.lpl.arizona.edu/ESP_032722_2405

  Changing gullies have so far been documented only in the Southern
  Hemisphere, where a greater thickness of carbon dioxide frost forms in the winter.
