In this interesting VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 23rd, 2015, and during its 60.737th orbit around the Red Planet, we can see that Impact Craters' Floors can have a wide range of different Surface Features, going from just Flat Areas, to Complex Central Peaks, or even a Single Central Pit. In this case, this Unnamed Impact Crater, located in the Martian Region known as Terra Sabaea, has, as you can see, a Central Pit-like Feature.


The different Floor Features visible in this picture developped (---> were created) baceause of the occurrence (most likely) of several concurring factors, including the size of the Impactor, the Geology of the Surface Material and the Geology of the Materials found in the Sub-Surface of Mars, or even deeper underground.

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 20092) has been additionally processed, magnified to aid the visibility of the details, extra-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.
