Mars Odyssey THEMIS images - June 9-12, 2009

The following new images taken by the Thermal Emission Imaging System (THEMIS) on the Mars Odyssey spacecraft are now available:

• Polar Ridges (Released 9 June 2009)
  Intersecting linear ridges are found in several locations around the south polar cap.
• South Polar Textures (Released 10 June 2009)
  As spring turns to summer, the frost cover has been removed from the south polar cap. The surface textures seen in this VIS image are created by action of the sun on the icy cap.
• Crater Rim Channels (Released 11 June 2009)
  Channels dissect the northern rim of this unnamed crater in Terra Cimmeria.
• Terby Crater (Released 12 June 2009)
  This VIS image shows some of the eroded, layered crater fill material within Terby Crater.
