In this nice VIS image, taken by the NASA - Mars Odyssey Orbiter on May, 22nd, 2004, and during its 10.809th orbit around the Red Planet, we can see one of the many Mesas that make up the Martian Region known as Deuteronilus Mensae.


Deuteronilus Mensae, which is approx. 937 Km (such as about 581,877 miles) across, and it is centered at 43° 54' North Lat. and 337° 24' West Long., lies just to the North of Arabia Terra and it is included in the Ismenius Lacus Quadrangle of Mars, along the so-called Dichotomy Boundary - such as a sub-Region located between the old, heavily cratered Southern Highlands and the low Plains of the Northern Hemisphere of the Red Planet


Deuteronilus Mensae is to the immediate West of Protonilus Mensae and Ismeniae Fossae. A few Glaciers persist in this Region even in modern times, with at least one of them which appears to be (geologically speaking) "relatively" recent - meaning that its formation, in other words, should have occurred as recently as about 100.000 to (only!) 10.000 years ago.

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 19772) 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.
