In this (relatively "old", but always smply beautiful) VIS image, taken by the NASA - Mars Odyssey Orbiter on July, 19th, 2002, and during its 2.637th orbit around the Red Planet, we can see, oce again (just like after yesterday's APOD) a small portion of the huge Martian Canyon known as Coprates Chasma (---> the Abyss of Coprates). Coprates Chasma belongs to (---> is just part of) the Great Valles Marineris Canyon System, it is approx. 966 Km (such as about 599,886 miles) long and it was so named after a so-called "Classical Albedo Feature".

If you pay attention, on the lower left (Sx) side of the frame (---> West/South-West of the pictured Region), you will be able to se the margin of a massive (and now highly eroded - likely by a powerful Aeolian Action) Landslide. Last, but not least, the gray-colored areas - visible both towards the left (Sx) and in the central/upper portion of the picture - are, most likely, relatively flat Rocky Locations where the Orangish Dust that keeps (almost continuously) falling on Mars, did not set (probably because of the presence of very Low Altitude Winds and strong Air Currents).

This image (which is an Original Mars Odyssey Orbiter false colors and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19008) 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.
