This excerpt of a Mars Global Surveyor Mars Orbiter Camera
daily global color mosaic shows typical afternoon
clouds over each of the large Tharsis volcanoes (left). Clouds
are white and bluish-white features in this image. Olympus
Mons is in the upper left corner. The three Tharsis Montes run diagonally
from upper center toward lower left--in order,they are Ascraeus Mons,
Pavonis Mons, and Arsia Mons. Together, the three Tharsis Montes cover
an area that would stretch down the west coast of the United States from
the border between Washington and Canada at the north end to the
Mexico/California border in the south. The Valles Marineris--a giant
system of chasms and troughs--stretches across the center right side of
the picture. The Valles Marineris would stretch all the way across the
United States, from Los Angeles on the west side to New York in the east.
This is a portion of the global image shown in
MGS MOC Release MOC2-143.
The mosaic shows images from a single day during the martian northern
summer in April 1999.
Malin Space Science Systems 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.
