Craters-Unnamed_Craters-ESP_031292_1295-PCF-LXTT-IPF.jpgUnnamed Craters in Hellas Planitia (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)76 visiteIn this frame, taken by the NASA - Mars Reconnaissance Orbiter on March, 30, 2013 and showing us a small portion of the Southern Martian Region known as Hellas Planitia, we can see - litterally lost in a "Sea" of Sand that has also been heavily marked by the passage of a countless number of Dust Devils - two relatively small Unnamed Impact Craters which are going through two very different (and very distant, in terms of time) moments of their evolution.
Barely visible, on the left (Sx) side of the picture, there is an extremely old and now almost completely "Buried Impact Crater", whose Rim, however, can still be discerned from the surrounding landscape; on the right (Dx) side of the frame, instead, a way more recent Unnamed Impact Crater that shows a very well defined (and therefore - of course, always relatively speaking - "fresh") Rim, with signs of a Landslide, that has occurred on its Inner Southern Slope, and also with what appears to be just a hint of a light-colored Windstreak on its Northern Outer Rim. Also a few Gullies can be spotted in several locations of the Inner Slopes of the Crater (particularly on its North-facing Inner Rim and Slope).

ESP_031268_2115-PCF-LXTT-IPF-0.jpgUnusually-looking Surface Feature (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)66 visiteThis image, taken by the NASA - Mars Reconnaissance Orbiter on March 28, 2013, shows us a number of shallow and Irregular Pit-like Features with Raised Rims, all concentrated along Ridges and other Topographic Features (---> Surface Reliefs). How did these unusually-looking Surface Features form? One idea is that they could be the final and visible result of the Sublimation of shallow lenses of nearly pure Ice but, even assuming that this theory is correct, why do the Pits have Raised Rims? So far, nobody was good enough to answer to that question.
If we keep reasoning about the possible nature of these Surface Features, we also have to say that they cannot - reasonably - be just shallow Impact Craters, because such an alignment seems extremely unlikely (and the irregular margins of the alleged "Impact Craters" would be even harder to explain); furthermore, these Landforms cannot even be Wind-blown Deposits of Material because, all the way next to them, can be seen very many Boulders which are way too big (and therefore too heavy!) to be moved simply by the Wind.
As you can see, there are younger Wind-blown Drifts on top of the Pits and, for the time being, we have not found a clear (---> substantiated) connection between these Landforms and some possible Volcanic Phenomenon. However, a few Planetary Scientists speculated that there might have been ancient Oceans over this Region, but could this possibility, even if it is correct, somehow be good to satisfactorily explain these Features? The answer is no. Last, but not least, what we see in this frame could also be the result of an ancient Glaciation where, perhaps, powerful Winds deposited Ice-rich Debris next to Topographic Obstacles.
Future (and closer) images of this Region may provide us with more clues but, for now, this Landforms are still a mystery. Just one of the many, of course...

Craters-Kasimov_Crater-ESP_030609_1550-PCF-LXTT-IPF-3.jpgInverted Channels in Kasimov Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia/Italian Planetary Foundation)75 visiteBy slightly enhancing an Absolute Natural Color image such as the EDM (see the inset to the right of the CTX Frame, which represents an about 1-Km wide - such as 0,621 miles - section of the whole area photographed by the NASA - Mars Reconnaissance Orbiter), can help us to achieve a better understanding of the imaged Surface Features, as well as to clearly distinguish between Surface Materials possessing different Histories, Textures and Mineral (---> Chemical) Compositions.
The whole image shows us a portion of the Floor of the Martian Impact Crater named "Kasimov" (a large - approx. 91 Km in diameter - and extremely ancient Impact Crater located in the Southern Hemisphere of the Red Planet), with several brown-gray (with subtle reddish nuances) Ridges that run from the bottom center to the upper left side of the frame. If you look carefully at all these different Ridges, you will notice that the Main Ridge is joined by a smaller one (look at the central portion of the CTX Frame) like small Tributary Rivers join together with larger ones on Earth. Indeed, this is exactly what happened here, on Mars, but - most likely - a few billions of years ago.
These Ridges are called "Inverted Channels" and they mark the locations of ancient Martian Riverbeds (in this case the Main River flowed towards the upper left of the image). Such Inverted Channels formed because the bottoms of these Rivers (---> Tributaries) were all full of Gravel-sized Rocks, whereas the areas around them were made of fine Clays. A VERY long time after the Rivers stopped flowing and dried-up, the Wind, slowly, removed completely the fine and light Clays, but it was not strong enough to blow away the heavy Gravel. In the end, after all the Clays were gone, the old Riverbeds were left as High-standing Gravel Ridges, such as the ones very well visible here (both in the CTX Frame as well as in the EDM).

ESP_030609_1550) and the EDM (which is an Original Mars Reconnaissance Orbiter enhanced color frame, identified by the serial n. ESP_030609_1550-1) have both been additionally processed and then colorized (as far as the EDM is concerned, re-colorized) in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Reconnaissance Orbiter and then looked down, towards the Surface of Kasimov Crater - 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 Kasimov Crater, each having a different Albedo (---> Reflectivity) and Chemical Composition.MareKromium     (3 voti)

ESP_025010_2650-PCF-LXTT-IPF.jpgOn the North Polar Scarp (EDM - Absolute Natural Colors; credits for the additional process. and color. Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)80 visiteThis image, taken by the NASA - Mars Reconnaissance Orbiter in the late November of the AD 2011, was acquired in order to monitor the effects on the North Polar Scarp of the so-called "Frost Avalanches" that occurred the year prior. HiRISE often re-images certain areas of Mars so to track those changes which, over time, might have occurred in some particularly interesting Regions and, in this case, the NASA People wanted to photograph the North Polar Scarp near the onset of the Martian Springtime, so to get a better understanding, among other things, of the number, extent and frequency of these Frost Avalanches; their possible causes (beside the thawing ---> the fact that Ice, Snow, or other frozen substances, start to become liquid, or just soft, as a result of warming) and the role that they have in the evolution of the North Poalr Scarp itself.
It is a fact that, even though the HiRISE has captured the occurrence of many other Frost Avalanches in the past, their view never ceases to amaze, since it demonstrates (but we, as IPF, just like many other Researchers and Scientists all over the World, had no doubts about it) that there still are, even at present time, several Active Geologic and Atmospheric Processes which keep happening (or regular bases) on the Red Planet. And this one, in other words, is just "one of the many"...

ESP_029516_1730-PCF-LXTT-IPF-2.jpgFeatures of Hydrae Chasma (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)85 visiteHydrae Chasma is a deep, almost Circular Depression approximately 50 Km across, situated between Juventae Chasma (to the North) and the large Canyon System known as Valles Marineris (to the South). This Chasma (---> Abyss) has steep Walls, flanked by numerous Landslides and a massive Scarp along its Southern Boundary, just where the Surface has collapsed into the Depression.
The EDM shows us an isolated flat-topped and small Mountain (known as a "Mesa") rising out of a Sea of Dunes located in the center of Hydrae Chasma. Darker-toned Dunes, likely composed of Basaltic Sands, form an Apron along the base of the Mesa's Northern Margin. The Western Side of the Mesa is gently sloping and is composed of a highly fractured light-toned Rubbly Base. It is overlaid by alternating light and dark Layered Cliff-forming Units and is covered by a Sediment Cap containing still more Dunes.
The Layered Sequences are present only in the Interior Deposits and not in the Walls of the Chasma. Similar Deposits can also be found on the Floor of the Valles Marineris Canyon System, as well as in other Chasmata (like Juventae, for instance), and may represent the Sedimentary Remnants of ancient (relatively) deep and quiet (---> with probably minimal Internal Streams) Martian Lakes that formed, eons ago, within all these Canyon and Depression Systems and which, in (a, likely, extremely long) time, slowly disappeared (---> evaporated, sublimed or just froze).

And so: what is this Circular Landform? It probably got its shape from an Impact Crater long ago, but was subsequently eroded and filled in, and then eroded again, so that now it is something like a "Low Mesa", surrounded by a Boulder-rich Geological Unit.
