Stereo (3-D) Views: Red/Blue Glasses Needed
For scale, two small squares in each image are 10 m
on a side, 40 m apart horizontally, and 10 m apart
vertically. (10 m = 10.9 yards; 40 m = 47.3 yards).

Through February 2000.



The data acquired by the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) during the period between September 1999 and February 2000--now available for viewing in the MGS MOC GALLERY at http://www.msss.com/moc_gallery/---include hundreds of pictures taken in support of the Mars Polar Lander mission before and after the attempted landing. Repeated efforts to find the lost lander during December 1999 and January - February 2000 resulted in several overlapping pictures taken from different angles as the spacecraft was pointed off its usual nadir---looking straight down---imaging position. Pictures such as these are perfect for 3-D, or, stereo, viewing. The context image on the right shows, at 20 meters (66 ft) per pixel, the mosaic of MOC images obtained to search for the lost lander. The four small white boxes show the locations of 3-D views in the picture on the left. To view these in stereo, you need red-blue "3-D" glasses (red filter over left eye, blue over right). Each stereo (3-D) image covers an area approximately 750 by 750 meters (about 1/2 a mile on a side). The terrain appears to be rugged, but the cause of this relief is unknown. Perhaps wind and frost have shaped this landscape. The Mars Polar Lander was lost during descent on December 3, 1999. Its location was not found in the MOC images (finding the lander would have been very difficult, because it is so small--smaller than a Volkswagen "Beetle"--and the camera was not really designed to see things that small; see Mars Polar Lander: The Search Begins). These images are located near 76.3°S, 195.0°W. North is toward the top and illumination is from the upper left. For scale, two small squares in each 3-D image are 10 m on a side, 40 m apart horizontally, and 10 m apart vertically (10 m = 10.9 yards; 40 m = 47.3 yards).

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.
