In this beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 17th, 2003, we can see a - relatively large and well defined - Unnamed Channel dissecting the Inner and Outer Rim of Moreux Crater, as well as the Materials carried and deposited on the Crater Floor by the Channel itself.
Moreux Crater is an Impact Crater located in the Ismenius Lacus Quadrangle of Mars, with a diameter of approx. 138 Km (such as about 85,698 miles). It is centered at 42,1° North Latitude and 315,6° West Longitude. Moreux Crater was so named after Dr Theophile Moreux, a French Astronomer and Meteorologist (he was born at Argent-sur-Sauldre, Cher on November, 20, 1867, and died at Bourges, France, on July, 13, 1954). Notice how strong is the texture as well as the color difference existing between the Outer Portion of Moreux Crater (orange/brown and uneven), as compared to the Crater's Floor (light and dark gray, quite smooth and poorly cratered).

This image (which is an Original Mars Odyssey Orbiter falsely colored and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19235) 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.
