MARS ODYSSEY THEMIS IMAGES
December 1-4, 2003

o Swirling Winds Reflected In Dunes (Released 1 December 2003)

  These dark transverse and linear dunes are located in the floor of a
  crater in the southern highlands. The dunes appear to follow the
  flow of winds that circle around the crater floor, creating a swirling
  pattern. Rather than swirling winds, however, the apparent arc may
  simply be caused by a north to south shift in the relative strengths of
  two winds that influence these dunes.

o Disappearing Act (Released 2 December 2003)

o Nili Fossae in Color (Released 3 December 2003)

o Hematite Outlier and Sand Dunes (Released 4 December 2003)

  This image shows a crater just south of the edge of the famous
  hematite-bearing surface, which is visible in the context image
  as a smooth area to the north. The crater has two features of
  immediate note. The first is a layered mound in the north part
  of the crater floor. This mound contains hematite, and it is an
  outlying remnant of the greater deposits to the north that have
  otherwise completely disappeared in this crater. The second feature
  is a dune field in the center of the crater floor, with dark dunes
  indicating winds from the northwest. The dunes grade into a dark
  sand sheet with no coherent structure, indicating that the sand
  layer thins out to the south and east.

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission
for NASA's Office of Space Science, Washington, D.C. The Thermal Emission
Imaging System (THEMIS) was developed by Arizona State University,
Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing.
The THEMIS investigation is led by Dr. Philip Christensen at Arizona State
University. Lockheed Martin Astronautics, Denver, is the prime contractor
for the Odyssey project, and developed and built the orbiter. Mission
operations are conducted jointly from Lockheed Martin and from JPL, a
division of the California Institute of Technology in Pasadena.
