MARS RECONNAISSANCE ORBITER HIRISE IMAGES
August 8, 2013

o Possible Cyclic Bedding within a Crater in Arabia Terra

  "Cyclic bedding" refers to a pattern of layering caused by repeated
  fluctuations in the amount of available sediment that creates new rock
  layers.

o Polygonal Surface Patterns at the South Pole

  Around the South Pole there are areas of this carbon dioxide ice that
  do not disappear every spring, but rather survive winter after winter.

o Diffuse Winter Lighting of the Chasma Boreale Scarp

  The diffuse light in this observation gives the image a unique appearance,
  almost like a painting.

o Bright Dunes in Syria Planum

  Features such as these hint that while modern Mars is relatively benign,
  the surface of the planet was battered by much more ferocious winds in
  the recent past.
