In this VIS image, taken by the NASA - Mars Odyssey Orbiter on May, 23rd, 2002, and during its 1.948th orbit around the Red Planet, we can clearly see some so-called "Chaotic Terrain" as welll as a small part of a Tributary Channel that empties into the Martian Region known as Ares Vallis.

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 18986) 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.
