In this VIS image, taken by the NASA - Mars Odyssey Orbiter (using an InfraRed Filter) on July 6th, 2013, and during its 51.284th orbit around the Red Planet, we can see a large section of the Channel known as Nanedi Vallis (a large Valley located in the Lunae Palus Quadrangle of Mars, at 4,9° North Latitude and 49,0° West Longitude. Nanedi Vallis is approx. 508 Km (such as about 315,4 miles) long and it was so named after the Sesotho (---> the National Language of the African Republic of Lesotho) word for "planet". Nanedi Valles is located between Shalbatana Vallis and the upper portion of Maja Valles and it is about 4 Km (approx. 2,484 miles) wide at its Northern End. Its shape is similar to the one of Nirgal Vallis (since both these Channels are very sinuous and show only a few - and short - Branches).

This frame (which is an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17438) has been additionally processed, magnified, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a 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.
