In an effort to save fuel so that the Mars Global Surveyor (MGS) mission can be extended additional years into the future (in order to act as a relay for entry, descent, and landing telemetry from the Mars Exploration Rover mission in early 2004), the spacecraft was re-oriented in mid-August 2001 such that it no longer points the camera and other science instruments straight down at Mars (i.e., towards its nadir). Now it points about 16 off-nadir. For the Mars Orbiter Camera (MOC) experiment, this new [sic] orientation, known among MGS teams as "Relay-16" (because it enables the "relay mission" and has an offset of 16), has resulted in a tremendous increase in the number of opportunities to acquire high resolution stereo (3-D) views of the martian surface. Ideally, an image taken during the Mapping Mission when the spacecraft was pointing nadir is repeated within a week or two of its first Mars anniversary--i.e., 1 Mars year after it was first acquired--so that the illumination conditions are close to the same in the two images.

The 3-D anaglyph shown here is an example of the on-going effort to acquire rRelay-16 stereo during the MGS Extended Mission. The first picture used to make this image, M13-01484, was acquired March 21, 2000. Nearly 1 Mars year later, the second image, E12-02584, was taken on January 23, 2002. Together, the images show eroded, pitted, light-toned layer outcrops in Iani Chaos near 4.4S, 18.6W. The layered materials may be ancient sedimentary rocks. The image covers an area 26 km (16 miles) by nearly 3 km (1.9 mi) wide, and is illuminated from the top left.

To see this image in stereo vision, you must use "3-D" glasses (red in left eye, blue in right). To see the original image from March 2000, visit M13-01484 in the MOC Gallery.

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.
