Features of Eumenides Dorsum (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

This frame, which is a mosaic of several orbital images obtained by the High Resolution Stereo Camera onboard the ESA - Mars Express Orbiter, shows us a number of Surface Features; in particular, and in addition to the presence of Plains, Buttes and just a few ancient and semi-buried Impact Craters, we suggest you to pay some special attention to the unbelievable complex of Sinuous Erosional Surface Striations, known as "Yardangs" (which are the most common Aeolian - meaning "sculpted by Wind" - Features that can be found on the Red Planet), that covers a huge portion of the central part of the picture.
All the abovementioned Surface Features are located in the Eumenides Dorsum Region of Mars, which lies to the West of the Tharsis Volcanic Province and forms part of the Region known as Medusae Fossae, at approx. 2° South Latitude and 206° East Longitude. The images here were taken on the date of December, 26, of the AD 2007; they have a ground resolution of about 13 meters per pixel and cover an area (in total) of about 12.000 square Km.
This frame (which is the Original ESA - Mars Express HRST b/w mosaic n. 424-20081105-5114-6-co-01-H1) has been additionally processed and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the ESA - Mars Express 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. Different colors, as well as different shades of the same color, mean, among others, the existence of different Elements present on the Surface of Mars, each having a different Albedo (---> Reflectivity) and Chemical Composition.
