In this VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 4, 2013 and during its 50.135nd orbit around the Red Planet, we can see a small section of Samara Valles: a very long and sinuous Valley bordering the Memnonia Quadrangle and the Margaritifer Sinus Quadrangle. Samara Valles is located at approximately 25,1° South Latitude and 19,1° West Longitude (or 340,9° East Long.); it is approx. 615 Km (such as about 381,9 miles) long and it was so named after the ancient name of the Somme River (France).
Latitude (centered): 25,0361° South

This frame (which is an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17103) has been additionally processed, magnified, contrast enhanced 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.
