NASA's Mars Global Surveyor shows a portion of dissected terrain southeast of Parana Valles on Mars.

Portion of dissected terrain southeast of Parana Valles (MOC 7705). This heavily gullied landscape (25.9°S, 8.3°W) shows the highest "drainage density" yet seen in MOC images. This image is somewhat lower in resolution (downtrack scale = 21.4 m/pixel, crosstrack = 14.3 m/pixel) but in other parameters comparable to Figures 1 and 2 (incidence angle = 27.5°, emission angle = 14.5°).

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.
