ZZ-Mercury-Craters-Balzac_Crater_and_others-PIA16907-PCF-LXTT-IPF.jpgCraters' Variety (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)118 visiteThis oblique view of the Surface of Mercury highlights, from top to bottom, the Impact Craters Balzac, Phidias,Tyagaraja, Stevenson, and Zeami. While named Impact Craters are still sparse across much of the Surface of Mercury, this Region, since it had already been observed by the NASA - Mariner 10 Spacecraft, granted to Planetary Scientists and Researchers plenty of time to propose names to the International Astronomical Union (or IAU, for short) and get them approved. Furthermore, in the NASA - Mariner 10 images of Mercury, Craters like Tyagaraja (located at the center of the image and having a diameter of approx. 97 Km - such as about 60,2 miles) and Zeami were described as hosting "Bright Floor Deposits", but the relatively low resolution at which they were imaged at that time did not allow the Planetary Scientists to carry out a more detailed analysis.
Now, thanks to the imaging capabilities of the cameras onboard the NASA - MESSENGER Spacecraft, we know that the Mercurian Impact Craters such as these visible in today's APOD, actually do not host "Bright Floor Deposits" but rather that fascinating (and still far from being fully understood) Features known as "Hollows".

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)94 visiteBerkel Crater (a Mercurian Impact Crater that was so named after the Turkish painter and printmaker, Sabri Berkel) is a so-called "Complex Impact Crater" (approx. 24 Km - such as a little less than 15 miles - in diameter) that sits inside the larger Ellington Basin, which is located in the low Latitudes of the Southern Hemisphere of Mercury. Berkel's interior contains some kind of Material (so far unknown) that, as you can clearly see in today's image, is way darker than the surrounding Terrain; furthermore, a large number of the vey common Mercurian Surface Features, known as "Hollows", can also be seen all over the Floor of the Crater itself.
This image was acquired as a targeted set of stereo images. Targeted Stereo Observations are acquired at resolutions much higher than that of the 200-meter/pixel Stereo Base Map. These targets acquired with the NAC enable the detailed Topography of Mercury's Surface to be determined for a local area of specific interest.

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.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)82 visiteOne of 9 (nine) newly named Mercurian Impact Craters, Pahinui, has intriguing Collapse-looking Pits surrounding its Central Peak. Pahinui Crater ha been so named after the Hawaiian musician Gabby Pahinui, a key figure in the 1970s Hawaiian Renaissance and master of the "slack-key guitar", a style that originated in Hawaii.
This image was acquired by the NASA - MESSENGER Spacecraft as part of the Mercury Dual Imaging System (MDIS)'s High-Resolution Surface Morphology Base Map. The Surface Morphology Base Map covers more than 99% of Mercury's Surface with an average resolution of 200 meters/pixel. Images acquired for the Surface Morphology Base Map typically are obtained at off-vertical Sun Angles (i.e.: high Solar Incidence Angles and therefore low Sun shining over the imaged Local Horizon) and have visible Shadows so as to reveal clearly the Topographic Form of many Geologic Features.

ZZ-Mercury-Limb-Flare-Fake-PIA16909-PCF-LXTT-IPF-0.jpgThis is NOT a "Game"!98 visiteThis beautiful and, as you can see, deeply suggestive image has been recently taken by the NASA - MESSENGER Spacecraft, while it was imaging the Limb of the Planet Mercury. What you see here could reasonably be an "Outgassing" - like the controversial ones which, sometimes, have been seen occurring on our Moon (actually, the so-called "Outgassings" are events in which Volatile-rich Materials are vented from deep inside the Lunar Interior, up to the Lunar Surface - specifically, we can think about Elements like Radon, Nitrogen, Carbon Monoxide, and/or Carbon Dioxide - and which might be the visible result of Low Level (---> Residual) Lunar Volcanic and/or Tectonic Activities). These Outgassing Phenomena, as you should know, are commonly put in the Cathegory of the so-called "Transient Lunar Phenomena" (or TLP, for short).-
On the other hand, this "Flare" might also be the result of an extremely unlikely (but yet possible) Residual Active Volcanic Activity (so, in this scenario, we would be looking at an actual Volcanic Plume) which happened on the innermost Planet of the Solar System: a Planet that has always been considered by the Planetary Scientists - as well as by the General Scientific Community -, like a (Geologically speaking) "Completely Dead Celestial Body".
It is also possible (even though we, as IPF, believe that this very last hypothesis is the least likely of the three) that the "Flare-like Light" seen here, on the Mercurian Limb, could be the evidence of an Impact (i.e.: a Meteor Strike) that has just occurred. However, if this hypothesis were true, we could also assume, just by looking at the shapes of both the Main Plume and the Upper Cloud which can be seen right on top of the Plume itself, that the Celestial Object that hit the Surface of Mercury should/must have followed a nearly (---> almost perfectly) Vertical Impact Trajectory (and this is another rather unlikely - better yet: extremely rare - circumstance).
This picture (which is an Original NASA - MESSENGER Spacecraft b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 16909 - but now, as we wrote herebefore, removed) has been additionally processed and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - MESSENGER Spacecraft and then looked down, towards the Surface of Mercury), 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 other things, the existence of different Elements (Minerals) present on the Surface of Mercury, each having a different Albedo (---> Reflectivity) and Chemical Composition.
Important Note for the Readers: the People working at NASA for The MESSENGER Team implied that this picture was (once again, after "Caduceus") some sort of "practical joke", created to celebrate the Worldwide famous "April Fools' Day". Well, we, as IPF, believe that if this picture, as it seems, is actually a "joke" (---> a fake, in this case), it really is a VERY, VERY poor and stupid one. Please, forgive us for being so direct, but even though some People may think that this idea of making a practical joke out of a MESSENGER b/w frame was "funny" and "educational" (and, in a pretty distorted way, it probably was so), we honestly believe that this silly "stunt" only proves, in a LOUD and CLEAR WAY, how easily, once you have the right REPUTATION, skills and means, the original RAW image-data received from Space can be corrupted/tampered with, either by adding or by removing Features.
As you can also easily understand, the implications arising out of this "stunt" are, actually, countless and, in a way (like we already underlined in the past), quite disturbing...

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.

Fienga - Lunar Explorer Italia/Italian Planetary Foundation)88 visiteProkofiev Crater, so officially named in August 2012 after the Russian composer, is the largest Impact Crater (with a diameter of approx. 112 Km - such as about 69,5 miles) located in Mercury's North Polar Region which hosts Radar-Bright Surface Material. Furthermore, the NASA - MESSENGER Spacecraft has also found evidence that within the cold, dark, and permanently shadowed Inner Regions of Prokofiev, Water Ice is exposed on the Mercurian Surface, just like it seems to happen on the Floors of extremely deep and steep Impact Craters and Canyons located near and at the Poles of our own Moon.
