3D- Visualization of Mars Terrain using Mars Color Camera Images onboard MOM

A fly-through of mars, covering Valles Marineris region was created by Space Applications Centre (SAC) using Mars Color Camera (MCC) Image.   This fly-through takes to hovering around Oudemans, Calydon Fossa, Louros Valles  Arima, Ophir and Perrotin features.

Valles Marineris is the largest canyon system about 4000 km long, 200 km wide and 7 km deep. This image also shows Noctis Labyrinthus at bottom left corner of the image. Fracture patterns at the center of Valles Marineris and northern portion of Noctis Labyrinthus are clearly seen.

The Noctis Labyrinthus, located at the western edge of the Valles Marineris Rift System, is a jumbled terrain composed of huge blocks which are heavily fractured. Eroded deposits located in central portion (floor) of Valles Marineris are clearly seen in this image. Regional contacts / fracture pattern running parallel to Valles Marineris, Arima crater located south of Valles Marineris is also seen in this image. Wall of the canyon are also seen.

Images of Valles Marineris and adjoining regions of Mars taken by MCC on board MOM are used in generating the fly-through. The MCC image was captured on November 10, 2014 at an altitude of 16,972 km. The spatial resolution of image is 882 m. The data was corrected by normalizing the radiometry with topographic effects. Subsequently, the image is draped over Planet Mars topography in the region of coverage mentioned above. Topography data has been smoothed for visual appeal.

Mars Digital Elevation Model from Mars Orbiter Laser Altimeter (MOLA) of Mars Global Surveyor mission is used as Topography Source. Mars Digital Image Mosaic from Viking missions is used as background planet texture. The video is generated by DECU, SAC, Ahmedabad.
