Mars Global Surveyor
Mars Orbiter Camera
Melas Chasma Floor
MGS MOC Release No. MOC2-104, 25 March 1999
The Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) continues
to provide a stunning array of images that show the red planet to
have a very diverse collection of surface textures and properties.
This picture shows a 3 kilometers (1.9 miles) by 4.4 kilometers (2.7 miles)
portion of the floor of Melas Chasma. Dark sand dunes spaced 55 to 60
meters (~190 feet) apart dominate the floor of this portion of the
Valles Marineris canyon system. Smaller ripples are also visible in
the troughs between some of the dunes, perhaps indicating a modern,
dynamic eolian (i.e., wind-swept) environment. Illumination
is from the upper left.
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.
