MARS GLOBAL SURVEYOR IMAGES
December 4-10, 2003

The following new images taken by the Mars Orbiter Camera (MOC) on
the Mars Global Surveyor spacecraft are now available:

o Polygons near Lyot Crater (Released 04 December 2003)
  http://www.msss.com/mars_images/moc/2003/12/04/index.html

  This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image
  shows patterned ground, arranged in the form of polygons, on the
  undulating plains associated with ejecta from the Lyot impact
  crater on the martian northern plains. This picture was acquired
  in October 2003 and shows that the polygon margins are ridges with
  large boulders---shown here as dark dots---on them. On Earth,
  polygon patterns like this are created in arctic and antarctic
  regions where there is ice in the ground. The seasonal and
  longer-term cycles of freezing and thawing of the ice-rich ground
  cause these features to form over time. Whether the same is true
  for Mars is unknown. The polygons are located near 54.6°N, 326.6°W.
  The image covers an area 3 km (1.9 mi) wide and is illuminated
  from the lower left.

o Tithonium Chasma's Sedimentary Rocks (Released 05 December 2003)
  http://www.msss.com/mars_images/moc/2003/12/05/index.html

o Crater in Marte Vallis (Released 06 December 2003)
  http://www.msss.com/mars_images/moc/2003/12/06/index.html

  This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image
  shows a streamlined tail--pointing toward the upper right
  (northeast)--in the lee of a meteor impact crater in Marte Vallis,
  a large valley and channel complex southeast and east of the Elysium
  volcanic region. The fluid that went through Marte Vallis, whether
  water, mud, lava, or otherwise, created this form as it moved from
  the lower left (southwest) toward the upper right. The crater is
  located near 19.0°N, 174.9°W. The image covers an area 3 km
  (1.9 mi) wide and is illuminated from the left.

o Small Dust Storm in Syria/Claritas (Released 07 December 2003)
  http://www.msss.com/mars_images/moc/2003/12/07/index.html

o Troughs in Tempe Terra (Released 08 December 2003)
  http://www.msss.com/mars_images/moc/2003/12/08/index.html

o Wind-Eroded Terrain near Olympus Mons (Released 09 December 2003)
  http://www.msss.com/mars_images/moc/2003/12/09/index.html

o Layers in Tithonium (Released 10 December 2003)

Mars Global Surveyor was launched in November 1996 and has been
in Mars orbit since September 1997. It began its primary
mapping mission on March 8, 1999. Mars Global Surveyor is the
first mission in a long-term program of Mars exploration known as
the Mars Surveyor Program that is managed by JPL for NASA's Office
of Space Science, Washington, DC. Malin Space Science Systems (MSSS)
and the California Institute of Technology built the MOC
using spare hardware from the Mars Observer mission. MSSS operates
the camera from its facilities in San Diego, CA. The Jet Propulsion
Laboratory's Mars Surveyor Operations Project operates the Mars Global
Surveyor spacecraft with its industrial partner, Lockheed Martin
Astronautics, from facilities in Pasadena, CA and Denver, CO.
