Summary

Description	English: Mars Viking Hemisphere Point Perspectives - Viking orbiter - 1980 Planet Mars https://astrogeology.usgs.gov/maps/mars-viking-hemisphere-point-perspectives https://astrogeology.usgs.gov/search/details/Mars/Viking/valles_marineris_enhanced/tif Valles Marineris Hemisphere Enhanced Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 2500 kilometers from the surface of the planet, with the scale being .6km/pixel. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene (lat -8, long 78) shows the entire Valles Marineris canyon system, over 2000 kilometers long and up to 8 kilometers deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 25 kilometers high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.
