B-Mercury-PIA02240.jpgThe components of the surface of Mercury98 visiteCaption NASA originale:"Updated calibration and subsequent mosaicing have led to substantial improvements in the Mariner 10 color image data. This color composite was formed to especially highlight differences in opaque minerals (such as Ilmenite), Iron content and soil maturity.
K - Crater Kuiper shows color consistent with fresh material excavated from a subsurface unit that may have an "unusual" composition;
D - relatively dark and blue unit consistent with enhanced Titanium content;
B - bright red unit that may represent primitive crustal material
F - color unit that follows plains boundaries, interpreted as lava flows".

ZZ-Mercury-Craters-Unnamed_Impact_Crater_with_Pond-PIA18371-PCF-LXTT-IPF.jpgImpact's Melt "Pond" (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)144 visiteThis High-Resolution Contextual (CTX) Image, taken by NASA - MESSENGER Spacecraft on the date of March, 10, 2014, shows us a few Ponds (---> small Lake-like Features) made of Impact Melt (remember that this kind of Surface Features appear to us way smoother than the Terrain which surrounds them).
In particular, these Melt Ponds (where the bigger one looks like some sort of a Flat Ellipse, with its Major Axis measuring approx. 1 Km - and visible at about 10 o' clock of the frame) were deposited (probably) as Fluid Ejecta (---> such as Ejecta made of liquid or semi-liquid Rock) coming from an Unnamed Impact Crater located to the North (top) of the picture, but not visible here.

ZZ-Mercury-Craters-Scarlatti_Crater-PIA18215-PCF-LXTT-IPF.jpgScarlatti Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)131 visiteIn this image-mosaic, obtained by putting together three frames taken by the NASA - MESSENGER Spacecraft on March, 30, 2014, we can see, located almost at the center of the frame, the large (such as approx. 132 Km - such as about 81,97 miles - in diameter) Peak-Ring Basin known as Scarlatti.
While Scarlatti has a typical Peak-Ring in many respects, if you take a good look towards its North/Eastern Section (upper right side - Dx - of the Feature), you will be able to notice its "transition" to a relatively wide (in this case, approx. 30 Km - such as about 18,63 miles - across) sort of Collapse Pit, surrounded by High-Reflectance (white and reddish in color) Surface Material. This Pit (perhaps a Volcanic Vent or a Caldera, eons ago), according to several NASA Planetary Scientists, could have been - and we say, as IPF, reasonably, considering all the visible Features characterizing it - the site of some (most likely extremely ancient as well as really powerful) Explosive Volcanic Activity.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)94 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.

ZZ-Mercury-Craters-Unnamed_Craters-PIA17827-PCF-LXTT-IPF-00.jpgMercurian Nightfall (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)91 visiteWith the Sun already extremely low in the Sky over this Mercurian Region located in the Northern Hemisphere of the Innermost Planet of the Solar System (the Sun is only about 8° above the imaged Local Horizon), the long, deep and dark Shadows created by this specific Spatial Configuration, accentuate the very uneven (---> highly irregular) nature of the Terrain.
In fact, the Surface visible here (---> we are looking at a scene which is about 14,6 Km - such as a very little more than 9 miles - across) has been battered - for eons and eons - by a countless number of Meteors and other Cosmic Impactors, until the Hilly Surface that exists and we can see today was finally created. For the most attentive Viewers, we, as IPF, strongly suggest you to take a careful look at the (very unusually-looking) Surface Feature (probably an oblong Secondary Crater with a strange - and still illuminated - Central Peak) that is located on the lower portion of the frame, slightly towards the left (Sx).

Terror Rupes is one of Mercury's most prominent Lobate Scarps, and it was so named after the HMS (---> Her Majesty's Ship) Terror: an eighteenth-century warship that, later, participated in Scientific Polar Explorations.

The fascinating Peak-Ringed Impact Basin named Wang Meng (whose diameter is approx. 165 Km - such as about 102,465 miles) is visible toward the Mercurian Horizon, slightly to the left portion of the frame, while the Pit-Floored Impact Crater Glinka can be seen near the bottom left of the picture. Last, but not least, the Impact Crater known as Judah Ha Levi is about half way in between the first two that we mentioned herebefore.

ZZ-Mercury-Craters-Unnamed_Craters-CB-PIA17692-PCF-LXTT-IPF-0.jpgOn the Edge of Caloris Basin (CTX Frame - Possible Absolute Natural Colors; credits for the additional process. and color. Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)101 visiteThis picture, which is an image-mosaic made of 3 (three) frames taken by the NASA - MESSENGER Spacecraft on October, 24, 2013, features several Unnamed Impact Craters (being the larger one, visible near the top of the image, approximately 54 Km - such as about 33,53 miles - in diameter) that are all located in the proximities of the Eastern Edge of the Giant Caloris Basin. The two larger Unnamed Impact Craters seen here have excavated (obviously, at the time of their formation, and according to NASA's Scientists) "Low Reflectance Material", and they both show extrenmly bright Hollows (which, in fact, caused an oversaturation of the picture in the areas where thay are present) within their relatively flat Floors.
The Orange/Reddish Deposits visible in the North/Eastern Quadrant (---> center and upper right corner) of the scene, exhibit a so-called "Spectral Signature" that is similar to the one usually left by Pyroclastic Deposits, and this circumstance suggests that this Region (just like way many others on Mercury) might have, once, been the Site of Explosive Volcanism.

ZZ-Mercury-Volcanic_Features-Vent-PIA15245-PCF-LXTT-IPF.jpgVolcanic Vent on the Edge of Caloris Basin (Absokute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)70 visiteThis kidney-shaped Surface Depression (which is approximately 23 Km - such as 14,283 miles - across its longest dimension) lies along the Inner Margin of the giant Caloris Basin and it was first imaged during the NASA - MESSENGER Spacecraft's first Fly-By of the innermost Planet in the Solar System, about 2 years ago. The Rimless, non-circular Surface Depression is, in fact, the Vent of a small, explosive Volcano, and it is similar to many other Volcanic Vents that have been discovered on Mercury. The small number of superposed Impact Craters indicates that this Feature is, just in a manner of speaking, relatively "young" as to the surrounding Terrain. Notice, also, the considerable number of bright Hollows that seem to characterize a large portion of the Inner Rim as well as the East-facing Slopes of the small Impact Crater located right outside the Eastern Margin of the Vent, at about 4 o'clock of the Main Feature.
Note: for another view of this Volcanic Vent and its extremely interesting surroundings (seen on a larger scale), please refer to the APOD of December, 22nd, 2012.

ZZ-Mercury-Craters-Donalaitis_Crater-PIA16958-PCF-LXTT-IPF-1.jpgDonelaitis Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/IPF)125 visiteThis composite of three frames, taken by the NASA - MESSENGER Spacecraft in August 2011, shows us the recently named Donalaitis Crater (whose diameter is approx. 84,5 Km - such as about 52,47 miles - and it lies well visible at the center of the image). As you can see, this Complex Mercurian Impact Crater exhibits some extremely unusually-looking bright yellow-orangish Deposits on its Floor. These colorful and very bright Deposits, as you may easily notice, contrast starkly with the much darker and gray colors (with pale brown/reddish nuances and some brighter white spots - where the latter could be, perhaps, some Hollows-covered areas) of the surrounding (and highly cratered) Terrain.
Donelaitis Crater was named after Kristijonas Donelaitis (1714 - 1780), a Lithuanian poet. His classic poem, 'The Seasons (Metai)', describes the lives of Lithuanian peasants, who at the time of its writing were being pushed into serfdom as most of their country was annexed by the Russian Empire.
