MARS GLOBAL SURVEYOR
Image of the Week
November 13, 2006

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

o Mars at LS 137 Degrees (Released 07 November 2006)
  http://www.msss.com/mars_images/moc/2006/11/13

Image Caption:

These images capture what Mars typically looks like in mid-afternoon
at Ls 137 degrees. In other words, with the exception of occasional
differences in weather and polar frost patterns, this is what the
red planet looks like this month (November 2006).

Six views are shown, including the two polar regions. These are
composites of 24-26 Mars Global Surveyor (MGS) Mars Orbiter Camera
(MOC) daily global mapping images acquired at red and blue
wavelengths. The 'hole' over the south pole is an area where no
images were obtained, because this polar region is enveloped in
wintertime darkness.

Presently, it is summer in the northern hemisphere and winter in
the southern hemisphere. Ls, solar longitude, is a measure of the
time of year on Mars. Mars travels 360 degrees around the Sun in 1 Mars
year. The year begins at Ls 0 degrees, the start of northern spring and
southern autumn. Northern summer/southern winter begins at Ls 90 degrees,
northern autumn/southern spring start at Ls 180 degrees, and northern
winter/southern summer begin at Ls 270 degrees.

Ls 137 degrees occurs in the middle of this month (November 2006). The
pictures show how Mars appeared to the MOC wide angle cameras at
a previous Ls 137 degrees in March 2001. The six views are centered on
the Tharsis region (upper left), Acidalia and Mare Eyrthraeum
(upper right), Syrtis Major and Hellas (middle left), Elysium and
Mare Cimmeria (middle right), the north pole (lower left), and
the south pole (lower right).

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.

Mars Global Surveyor Image of the Week - October 10, 2006

MARS GLOBAL SURVEYOR 
Image of the Week
October 10, 2006

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

o Summertime View of North Polar Sand Dunes (Released 10 October 2006)
  http://www.msss.com/mars_images/moc/2006/10/10

Image Caption:
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a 
suite of dunes in one of the several north polar dune fields. The bright 
surfaces adjacent to some of the dunes are patches of frost. These dunes 
spend much of the autumn, winter, and spring seasons covered with carbon 
dioxide frost. Only in late spring and in summer are the dark windblown 
sands fully exposed.

Over the course of the 9+ years of the MGS mission, the MOC team has 
sought evidence that sand dunes may be migrating downwind over time. 
However, no clear examples of the movement of a whole dune have been 
identified. On Earth, such movement is typically detectable in air 
photos of the smallest active dunes over periods of a few years. Owing 
to the fact that the north polar dunes spend much of each martian year 
under a cover of frost, perhaps these move much more slowly than their 
frost-free, terrestrial counterparts. The sand may also be somewhat 
cemented by ice or minerals, likewise preventing vigorous dune migration 
in the present environment.

This view covers an area approximately 3 km (1.9 mi) wide and is 
illuminated by sunlight from the lower left. The dunes are located 
near 79.8N, 127.1W, and the picture was acquired on 11 September 2006.
