In this, once again, interesting, but "foggy" VIS image, obtained by the NASA - Mars Odyssey Orbiter on September, 16th, 2009, during its 34.410th orbit around the Red Planet, we can see part of the Eastern Wall of Ophir Chasma (which is nothing else but a deep Canyon located in the Coprates Quadrangle of Mars, and centered at about South Latitude and 72,5° West Longitude). Ophir Chasma is approx. 317 Km long and it was so named after a so-called "Classical Albedo Feature".


Latitude (centered at approx.): 3,98145° South

This image (which is a crop obtained from an Original Mars Odyssey Orbiter falsely colored and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20250) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then re-colorized in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
