In this VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 2nd, 2015, and during its 58.617th orbit around the Red Planet, we can clearly see, among other things, at least one huge Linear Surface Depression that crosses the Southern Part of a relatively (Geologically speaking) recent and really irregularly-shaped Unnamed Impact Crater (maybe a Secondary Crater?) with a large Pedestal, that is located in the Martian Region known as Sirenum Fossae.


This Linear Depression is, most likely (has NASA's Planetary Scientists say, but we have no way to be sure about that - and, in addition, we, as IPF, totally disagree with such an interpretation, that seems truly superficial and unsubstantiated), a Tectonic Fracture that - just like many others - is, in fact, hundreds of kilometers long and over a few million years old.

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19440) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then 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.
