MARS RECONNAISSANCE ORBITER HIRISE IMAGES
February 29, 2012

o Sand Dunes in the Spring
  http://hirise.lpl.arizona.edu/ESP_025416_2640

  In the spring as the ice sublimates (goes directly from solid to
  gas) numerous seasonal phenomena are observed.

o Dunes on Ridges
  http://hirise.lpl.arizona.edu/ESP_025625_1580

  These dunes may be active today, but we haven't yet observed them
  at significantly different times to measure the movement.

o Old Salt
  http://hirise.lpl.arizona.edu/ESP_025625_1580

  These patches are very similar in color, morphology, and geologic
  setting to larger deposits thought to consist of chloride salts,
  like table salt.

o Tilted and Layered Bedrock Blocks in a Large Crater inside Becquerel Crater
  http://hirise.lpl.arizona.edu/ESP_025782_2020

  There is a crater nearly 50 kilometers in diameter inside the 167-kilometer
  Becquerel Crater, named after Antoine Henri Becquerel, the discoverer of
  radioactivity along with Marie and Pierre Curie.
