In this really nice VIS image, taken by the NASA - Mars Odyssey Orbiter on December, 11th, 2015, and during its 62.074th orbit around the Red Planet, we can see an Unnamed Impact Crater located in the Northern Hemisphere of Mars, in the Region known as Acidalia Planitia. The Outer Margins of the Ejecta Blanket have a lobated shape and they are, as you cans see, quite higher than the Inner Margins (such as the Margins of the Blanket which are closer to the Crater itself). This type of Ejecta Blanket is commonly called "Rampart" and it is thought (by Planetary Scientists) that a Volatile Material - such as an Element existing on the impacted Surface and/or in the Sub-Surface, like Water maybe, or a Gas of some sort - could have played a role in the creation of this kind of Morphology. The Unnamed Impact Crater visible here is fairly pristine, and - therefore - relatively young (always Geologically speaking, of course). Latitude (centered): 41,5210° North 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 20261) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced, Gamma corrected 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. |
