ZZ-Mercury-Craters-Unnamed_Crater-PIA16948-PCF-LXTT-IPF.jpg
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)134 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).

ZZ-Mercury-Craters-Faulkner_Crater-PIA16908-PCF-LXTT-IPF-0.jpgFaulkner Crater (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)122 visiteIn this picture, taken by the NASA - MESSENGER Spacecraft, we can see relatively young and smooth Lava Plains which have filled and partially (actually, almost completely) buried the Mercurian Faulkner Crater (approx. 168 Km - such as about 104,32 miles - in diameter), leaving only the Northern three-quarters of its highly degraded Rim visible. These smooth Lava Plains, which have relatively few superposed Impact Craters (and that is why they can be considered - always relatively speaking - "young") and appear of a light brown-pink color in this Absolute Natural Colors image, were - likely - emplaced when powerful Volcanic Flows breached Faulkner's Southern Rim, invaded the whole Floor of the Crater and then set, leaving only the highest-standing portions of Terrain (such as, as we wrote herebefore, some part of its Northern Rim) almost intact.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)81 visiteThis image (taken by the NASA - Messenger Spacecraft in middle February 2013), shows us an area of ~ 23 Km - such as about 14,28 miles - across that is located within an Unnamed Mercurian Impact Basin that has been litterally "etched" by Hollows. Out of curiosity, this is the only area within the Basin in which Hollows are found. To the bottom left portion of the frame, some part of the Peak Ring of the Basin can also be seen and, most likely, this Peak Ring has been heavily modified by a number of subsequent impacts.

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)74 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-Limb-PIA16820-PCF-LXTT-IPF.jpgSouthern Craters (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia/Italian Planetary Foundation)83 visiteThe set of 3 (three) frames shown here in Absolute Natural Colors and forming this image mosaic, was acquired by the NASA - MESSENGER Spacecraft as part of a sequence intended to monitor any changes in the calibration of the Multispectral Wide Angle Camera onboard the Spacecraft over time. However, the final result of this "calibration" also gives us a simply beautiful view of a wide portion (the whole scene is approx. 1900 Km - such as a little less of 1180 miles - across) of Mercury's heavily cratered Southern Hemisphere. Furthermore, the Impact Craters Magritte, Neruda, and Sher-Gil can be easily spotted within this scene. North is towards the top-left of the image.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)85 visiteThis image highlights the velvety texture that surrounds several Volcanic Vents located near the Outer Rim of the huge Impact Basin known as "Caloris Basin", on Mercury. This (apparently) soft texture, like freshly fallen snow, is formed by the emplacement of tiny beads of Lava that were explosively erupted and then quenched and solidified just before they reached the Surface. This diffuse Deposit heavily blankets several Impact Craters and older Vents, while it becomes thinner as long as it goes farther away from the Source of the Eruption. A large amount of the typical Mercurian Surface Features known as "Hollows" is also very well visible on the Rims of a number of Unnamed (and relatively modest in size) Impact Craters. This whole scene is approx. 106 Km across.

ZZ-Mercury-Volcanic_Regions-Plains-PIA16428-PCF-LXTT-IPF.jpgVolcanic Region (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)88 visiteMany Regions of Mercury's Surface show a relatively smooth and dark brown/reddish-colored Terrain (with almost black patches near and around the Rims of the major Impact Craters) that, in a way, appears to have "flooded" (---> quickly covered, either in whole or in part) low-lying Areas and, at the same time, which has also partially filled (and/or, here and there, almost completely buried) what seem to be the oldest Impact Craters existing on the Surface. Said that, we can reasonably speculate that these smooth Plains could have formed, in a very distant past of the Innermost Planet of the Solar System, as a consequence of the occurrence of some powerful Volcanic Activity which, in fact, ended up by - litterally - "drowning" these Regions with - and in - extremely voluminous amounts of, most likely, low-viscosity Basaltic Lavas.

Notice that the beautiful colors of the Mercurian Surface, as well as all the details of the Terrain seen here, all appear to be extremely clear, sharp and well visible, (also) thanks to to fact that the Sun, at the time that the picture was taken, was relatively high in the Sky (59,2° on the Local Horizon, to be exact).

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)80 visiteEven though quite a few Impact Craters are visible in this Absolute Natural Color view of Mercury's Limb, the Crater Degas (whose diameter is approx. 55 Km) gets easily noticed. Located near the center of the image, the distinctive gray color of the Low-Reflectance (---> Albedo) Material associated with Degas Crater (Material that covers most of the Floor, the Inner and Outer Rim, as well as a little bit of the Surface located in close proximity with the Crater itself) makes a clear contrast with the surrounding Terrain and neighboring Craters.
This image was acquired as a Targeted Observation that occurred simultaneously with a measurement carried out by the Mercury Atmospheric and Surface Composition Spectrometer (MASCS). Targeted Observations that involve both MDIS and MASCS, once the data from both instruments are combined, facilitate a better understanding of the color and reflectance of small-scale Geologic Features which are present on the Surface of Mercury.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)88 visiteGeddes Crater (so named, in March 2010, in honor of Wilhelmina Geddes (1887 - 1955), an Irish stained glass and graphic artist) is well known to be a Mercurian extremely geologically interesting Impact Feature. As you know, the Ridge of Antoniadi Dorsum bisects the Crater, and in the center of the Crater's Floor there is a large Depression with a distinctive orangish hue: a color similar to the one seen in other areas (still on Mercury and elsewhere in the Solar System, such as, for instance, on our Moon) which are (better yet: were) associated with Explosive Volcanism or other phenomena of (perhaps Sulphurous-rich) Outgassing. This recently acquired image reveals new, High-Resolution detail of such a potentially Volcanic Depression (---> a Volcanic - in origin - Collapse Pit, to be more specific, which might have formed as a consequenc of the progressive withdrawal of Subsurface Magma), including the presence of many Hollows (a Surface Feature that, as we know now, is extremely common and that can be found all over the Surface of Mercury and which do not seem to be only related, in our opinion, as IPF, to the verification of Impact Events).

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)81 visiteThe main and really impressive Impact Crater visible in this NASA - MESSENGER Spacecraft image, Eitoku (which has a diameter of approx. 100 Km - such as about 62 miles) , displays several (almost) Central Peaks that appear especially prominent due to the high Solar Incidence Angle (meaning that the Sun was setting onto the imaged Local Horizon at the time that this picture was taken - and therefore the shadows of each and every Mercurian relief resulted way more visible - i.e.: longer - and suggestive) as well as to the fact that this frame has not been Map Projected. Note that Central (and/or almost Central, like in this case) Peaks are a relatively common Feature in Mercury's larger Impact Craters. Note, also, that the smaller Impact Craters visible on the Floor and Rim (which, on its side, appears quite degraded) of Eitoku Crater indicate/suggest that we are actually looking at an old Impact Feature.

The Basin has a smooth, filled Floor with little weathering and a Peak-ring Structure. Shota Rustaveli was a Georgian poet who lived from 1172-1216. He is well known for writing the Georgian National Epic Poem, "The Knight in the Panther's Skin". He is also the namesake of the coveted Shota Rustaveli State Prize, the highest honor a Georgian artist or writer can achieve.
