In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 5th, 2015 and during its 58.313th orbit around the Red Planet, we can see, once again, after the APODs of June, 26 and September, 12, 2013, a truly small section of Samara Valles: a very long and sinuous Valley bordering the Memnonia Quadrangle and the Margaritifer Sinus Quadrangle.

The Samara Valles Valleys' System 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): 25,3069° South

This frame (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19274) 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.
