MARS RECONNAISSANCE ORBITER HIRISE IMAGES
January 27, 2016

o Pit Crater near Elysium Mons
  http://hirise.lpl.arizona.edu/ESP_043222_2035

  Pit craters are simply sink holes in the ground with near vertical
  walls and floors that are only visible when the sun is high in the sky.

o A Tale of Two Flows
  http://hirise.lpl.arizona.edu/ESP_043609_2230

  We will need to study this image in more detail to understand how these
  flows have interacted with each other and what they can tell us about their composition.

o The Changing Sands
  http://hirise.lpl.arizona.edu/ESP_043617_1885

  These barchan dunes have been imaged at least five times already, and each time, a
  bit more movement is revealed.

o Jarosite in Noctis Labyrinthus
  http://hirise.lpl.arizona.edu/ESP_043719_1725

  The jarosite-bearing deposit observed here could indicate acidic aqueous conditions
  within a volcanic system in Noctis Labyrinthus.
