MGS MOC Release Nos. M0C2-251 to MOC2-255, 16 October 2000
These Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) pictures
and their captions (select images below) illustrate some of the range of
martian features and image data obtained by the MOC during the second six-month
period that MGS was in its Mapping Orbit, from September 1999 through February
2000. Many of the pictures from this period are in the southern hemisphere
and were acquired to monitor the south polar cap as it retreated through
the spring season. Others in the south examined the Mars Polar Lander site,
both before the landing and afterward in attempts to learn of the Lander's
fate. The pictures shown below represent a tiny fraction of the variety
of things seen during this portion of the MGS mission; their purpose is
to accompany more than 30,000 NEW pictures released this month in the MSSS Mars Global Surveyor Mars Orbiter
Camera Gallery. These data have been validated by the MGS MOC Operations
Team at Malin Space Science Systems and are being deposited for permanent
archive with the NASA Planetary
Data System (PDS). The data validation process is important and labor-intensive;
new MOC data are submitted to the archive every six months.

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.
