Illustrations Regarding Early Mars Sedimentary Rocks
from the NASA/JPL Press Conference, December 4, 2000

MGS MOC Release No. MOC2-265, 4 December 2000


Note: Originally it was planned that there would be a "Space Science Update" televised from NASA Heaquarters in Washington, D.C., on December 7, 2000, to present Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) results regarding sedimentary rocks on Mars. That media event never transpired because Science lifted its usual embargo on December 4, 2000, and a hasty press conference at Caltech's Jet Propulsion Laboratory was put together to give the MGS MOC group a chance to describe their work. The following pictures were prepared for the December 7, 2000, Space Science Update. Not all of these were shown at the press conference that actually took place on December 4th. Pictures A, B, C, E, F, G, H, I, L, and several from O and P were used at the JPL Press Conference.

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.
