ZZ-Mercury-Craters-Theophanes_Crater-PIA16868-PCF-LXTT-IPF.jpgTheophanes Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)65 visiteThis image, taken by the NASA - MESSENGER Spacecraft in the early October 2012, shows the ancient Mercurian Impact Crater Theophanes (whose diameter is approx. 46 Km - such as a little more than 28,5 miles), which was originally imaged by the NASA - Mariner 10 Spacecraft.
This Impact Crater was named after the Byzantine iconographer known as "Theophanes the Greek". Though he was born in Constantinople, the Capitol of the Byzantine Empire, around the AD 1340, Theophanes spent most of his life in Russia, where he moved in the AD 1370, and it was right there that he gained notoriety as an icon painter. Some of his more prominent works include Our Lady of the Don and the Transfiguration of Christ. He is also known as the teacher and mentor of the great medieval Russian painter Andrei Rublev, the eponym of another Impact Crater located in the Southern Hemisphere of Mercury.
As you can se, the Hollows which characterize Thophanes Crater are all concentrated in a relatively flat area going from the North-East of Theophanes' Complex Central Uplift, until its upper margin (---> Inner Rim), but only in that portion of its Floor that is located in between (approx.) 1 to 2 o'clock. The reason of such a peculiar configuration of Theophanes' Hollows is (obviuosly) so far unknown, even though we, as IPF, have a theory about it, which we shall try to explain in the future.

ZZ-Mercury-Craters-Tiziano_Crater-PIA12079.jpgTitian Crater (extremely enhanced Natural Colors; credits: NASA and Lunar Explorer Italia)53 visiteThis enhanced-color image shows Titian Crater (center) and is similar to an image that recently appeared in the 1st of May 2009 issue of Science magazine.
The enhanced-color view was created by using high-resolution images taken in all 11 WAC filers (one of which is shown in a previously released image, see PIA11765) and comparing and contrasting them to accentuate differences on Mercury’s Surface. Such color differences can be used to learn about the history of Mercury’s Surface in this area. In the enhanced color, the smooth floor of Titian is a brighter orange color than the surrounding area, likely due to being filled with volcanic material. Ejecta from Titian appear blueish and cover much of the Surface surrounding the Crater. This material was excavated from depth during the Crater’s formation.
Later impacts, such as the one that produced the small crater that appears yellowish in the upper center of the image, excavated material from below the Titian ejecta. This yellow-appearing material was present at or near the surface before the impact that created Titian and is a different composition (and thus, color) from its surroundings. Impacts make it possible to assess how Mercury’s Crust varies with depth and ultimately how the crust evolved through time.

Nota Lunexit: curiosa la "chiazza violacea" visibile ad ore 01:00 del Cratere "Tiziano". La NASA, ovviamente, ha commentato tutto, tranne il dettaglio più intrigante. Noi, purtroppo, non possiamo aggiungere nulla, se non ribadire un concetto già espresso dalla NASA più volte, e cioè che "a colore diverso, nei frames colorizzati in natural enhanced colors, corrisponde un materiale diverso". Nulla di più.MareKromium

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)81 visiteIn this beautiful view obtained by the NASA - MESSENGER Spacecraft on November, 8, 2011, we can see, once again, prominent, near the center of the degraded Impact Crater To Ngoc Van, an interesting (and really irregularly shaped) Collapse Pit (approx. 20 Km - such as about 12,42 miles - across). As a matter of fact, many samples of Impact Craters with one (or more) Collapse Pit/s located on their Floors, have already been identified across the Mercurian Surface and - most likely - they all formed as a consequence of (extremely ancient) phenomena of Explosive Volcanism.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)95 visiteIn this beautiful Extra Detail Magnification (or "EDM" for short) which has been taken from a picture obtained by the NASA - MESSENGER Spacecraft on November, 8, 2011, we can see, once again, prominent, near the center of the degraded Impact Crater To Ngoc Van, an interesting (and really irregularly shaped) Collapse Pit (approx. 20 Km - such as about 12,42 miles - across). As a matter of fact, many samples of Impact Craters with one (or more) Collapse Pit/s located on their Floors, have already been identified across the Mercurian Surface and - most likely - they all formed as a consequence of (extremely ancient) phenomena of Explosive Volcanism. To be more specific, we, as IPF, do believe that the aforementioned phenomena of Explosive Volcanism that caused the formation of Pits inside a great number of Mercurian Impact Craters, was, most likely, triggered by the Impacts themselves and the subsequent powerful Shock-Waves that deeply altered the Sub-Surface of a Planet which - at the time when most of the Impacts took place - was still Geoilogically Active (we could say that, in those - remote - times when its Surface was so heavily battered, Mercury was, however, still "alive" - at least from a Geological point of view).

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)60 visiteThis image of the Limb of the Planet Mercury shows, among other fascinating Surface Features, the location of the Impact Basin Tolstoj (approximately 350 Km - such as about 217,35 miles - in diameter). The interior of Tolstoj is filled with smooth Plains while the exterior is largely made of the so-called Low Reflectivity Material (or LRO, for short). Just to give to our Readers an idea of the real dimensions and proportions of what is visible on this part of Mercury, you have to consider that today's frame is approx. 2770 Km (such as about 1720,17 miles) across.

ZZ-Mercury-Craters-Tyagaraja_Crater-PIA17051-PCF-LXTT-IPF-1.jpgTyagaraja Crater (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)57 visiteThis colorful picture of Tyagaraja Crater (which is about 97 Km - such as approx. 60,23 miles - in diameter) and its surroundings shows us many different types of Material that exist on the Surface of Mercury. For instance, the very bright, white areas visible on the Floor of the Crater (in particular to the North/East, at about 3 o'clock) are the very "famous" (and common, on Mercury) Hollows; as a matter of fact, they are so much brighter than the surrounding Areas that they appear slightly over-saturated in this particular image. The yellow/red/orangish spots located near the center of the Crater are, most likely, Volcanic Materials which surround a Pyroclastic Vent. Last, but not least, the very Dark Material (almost black) that is visible all around Tyagaraja Crater (and, particularly, towards the South/Western Regions surrounding Tyagaraja - such as the areas located in the lower left (Sx) side of the frame) is Low Reflectance Material (LRM). Just out of curiosity, if you look carefully at the outline of Tyagaraja Crater, you may notice that its shape is quite unusual for a Primary Impact Crater: in fact, its shape it is not a "circle", but rather an (almost regular, on its Western side) "hexagon".

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)111 visiteThis image - taken by the NASA - MESSENGER Spacecraft - shows us the Hollow-covered Central Peak Structure (a Feature that is also often called Central Uplift) of a Mercurian Northern Hemisphere's Unnamed Impact Crater having a diameter of about 60 Km (such as approx. 37,26 miles). It is now clear that these mysterious Mercurian Surface Features known as "Hollows" are not only related - as it was thought at the beginning - to (relatively) flat surfaces (such as the Floors of a countless number of Impact Craters) or on areas located near or on top of the Rims of said Impact Craters: it has been now visually proven that the Hollows can also be found on highly irregular (---> NOT "flat") and complex rocky structures (---> Central Peaks and, maybe, Hills and Mountains). And, in the meanwhile, the search continues...

ZZ-Mercury-Craters-Unnamed_Crater-PIA16948-PCF-LXTT-IPF.jpgUnnamed Crater with "Slump" Deposits (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)115 visiteThe Unnamed Impact Crater visible in this image taken by the NASA - MESSENGER Spacecraft shows prominent "Slump Deposits" that were created when the Crater Walls collapsed and, perhaps, some portion of the Ejecta, fell back down, inside the Crater itself. These events, according to NASA Scientists, probably occurred immediately (or just a VERY little time) after the Crater formation. If you look closely, you can also see that the Inner Rim appears to host small patches of Hollows. One clue to understand the Hollow formation is that they appear to form, preferentially (but NOT always!), on Sunward-facing Slopes (and since this Impact Crater is located at a high Northern Latitude, its Northern (Inner) Wall gets the most exposure to the Sun). This extra heating may enhance the sudden loss (---> escape) of the Volatiles that are present in and near the subsurface, thus creating those strange, bright Features that are now commonly known as "Hollows" (---> litterally: a "hollow" is a place that once was full of "something" - i.e.: Ice, Gases and/or other Volatiles like Nitrogen, Carbon Dioxide, Ammonia, Hydrogen, Methane and Sulfur Dioxide - and that now has become empty).
