ZZ-Mercury-Natural_Satellite-Caduceus-PIA15542.jpgNOT ALONE!236 visiteCaption NASA:"This discovery image provides the first evidence that Mercury has a small natural satellite or moon. Visible as a small bright spot in an image taken yesterday by the Mercury Dual Imaging System (MDIS) Wide Angle Camera (WAC), the moon is approximately 70 meters (230 feet) in diameter and orbits Mercury at a mean distance of 14.300 Km (such as 8890 miles). A proposal to name the moon "Caduceus", after the staff carried by the Roman god Mercury, has been submitted by the MESSENGER team to the International Astronomical Union, the body responsible for assigning names to celestial objects.
This discovery presents an unprecedented opportunity for a return of samples from the Mercury System, as Project Scientist Nat MacRulf explains. "We have yet to identify a sample from Mercury in any of the meteorite collections we have here on Earth. Such a sample would give us critical insight into the chemical composition of Mercury and the timing of crustal formation on that body, leading to a better understanding of how the planet formed and evolved. If we could obtain a sample of Caduceus, it would enhance the scientific return of the MESSENGER mission beyond our wildest dreams!"
Work on designing a scenario for sample return is already underway. MESSENGER Project Manager Burt Panini held an emergency meeting with the MESSENGER mission operations and navigation teams yesterday evening to determine if the spacecraft could be targeted toward the diminutive moon. After an intensive discussion, a unanimous decision was taken to abandon the orbit-correction maneuvers that had been planned for later this month to place the spacecraft in an eight-hour orbit. Instead, the new plan is to use the remaining propellant to crash MESSENGER into Caduceus. "Our detailed analysis tells us that if we act now, and with the right trajectory, MESSENGER will impart just enough momentum to the moon to break it free of Mercury's Gravity well and set it on an Earth-crossing trajectory suitable for recovery as a Mercury meteorite", said Panini.
This action will form the basis of a new request to NASA by the MESSENGER team for an extended extended mission, tentatively called "MESSENGER Infinitesimally Nudging Caduceus", or MIN-C for short. Once MIN-C is approved by NASA, the Spacecraft will be targeted for a collision trajectory. If Caduceus is successfully released from the pull of Mercury and placed on a course to reach Earth, we can expect the moon to arrive at Earth by 2014. "The risk to the public is reassuringly small", offers MESSENGER mission design lead Adam McJames. "We have designed a trajectory that will bring the moon to Earth at a remote location on the Wilkes Land ice sheet in Antarctica. This trajectory will avoid all population centers and will put the moon's impact site within reach for retrieval by the scientific staff at the U.S.-operated McMurdo Station".
If successful, MESSENGER's extended extended MIN-C mission will mark the first instance of the documented arrival to Earth of material from the Mercury system. Moreover, it will serve as the basis for a new Discovery-class mission proposal currently in development by the Applied Psychics Laboratory for a Mercury lander mission for in situ X-ray analysis of surface composition. That mission is to be named the Hermean On-surface Analysis with X-rays.

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-Praxiteles_Crater-PIA12052.jpgPraxiteles Crater (enhanced Natural Colors; credits: Lunar Explorer Italia)68 visiteMESSENGER's high-resolution images obtained during the mission's second Mercury flyby have revealed a number of irregularly shaped depressions on the floor of Praxiteles Crater. These depressions are intriguing indications of possible past volcanic activity within this Crater. View the previously released NAC image of Praxiteles for additional discussion.
The image shown here is similar to one recently published in the 1st of May issue of the "Science" magazine. This image was created by first mosaicking together the highest-resolution NAC images available of Praxiteles (one of which is shown in the previous web release), to produce complete coverage of the Crater. Independently, an enhanced-color image of Praxiteles was created by using images from all 11 WAC narrow-band color filters. (Visit last week's web release for more examples of enhanced-color images see PIA12051).
The WAC images provide important color information, but the WAC resolution is considerably less than that of the mosaicked NAC images. Thus, by overlaying a slightly transparent version of the WAC enhanced-color image on the high-resolution NAC mosaic, the high-resolution color view of Praxiteles crater shown here was produced. This overlay-color view helps associate the color features with the morphologic surface features. The fact that the irregularly shaped depressions on the floor of Praxiteles are associated with bright orange and yellow color features provides evidence that the depressions may be related to past volcanic activity in this area of Mercury.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)147 visiteToday's APOD (obtained by the NASA - MESSENGER Spacecraft during the past month of November) provides us with the best look yet at Basho Crater (approximately 75 Km - such as about 47 miles - in diameter): a (relatively) young Impact Crater located in the Southern Hemisphere of the Planet Mercury. Basho Crater features some of the most striking Albedo (---> Reflectivity) contrasts that can be found on the whole Surface of the Innermost Planet of the Solar System, with both Low-Reflectance Ejecta and High-Reflectance Deposits (probably the most "famous", common and yet highly controversial - as far as its origin is concerned -Mercurian Surface Feature ever discovered: the so-called Hollows).

ZZ-Mercury-Craters-Basho_Crater-PIA16625-PCF-LXTT-IPF.jpgBasho Crater (Absolute Natural Colors; credts for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)147 visiteToday's APOD (obtained by the NASA - MESSENGER Spacecraft during the past month of November) provides us with the best look yet at Basho Crater (approximately 75 Km - such as about 47 miles - in diameter): a (relatively) young Impact Crater located in the Southern Hemisphere of the Planet Mercury. Basho Crater features some of the most striking Albedo (---> Reflectivity) contrasts that can be found on the whole Surface of the Innermost Planet of the Solar System, with both Low-Reflectance Ejecta and High-Reflectance Deposits (probably the most "famous", common and yet highly controversial - as far as its origin is concerned -Mercurian Surface Feature ever discovered: the so-called Hollows).
Date acquired: November, 6th, 2012
Image Mission Elapsed Time (MET): 260649832
Image ID: 2901613
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Center Latitude: 32,47° South
Center Longitude: 189,2° East
Resolution: 103 meters/pixel
Solar Incidence Angle: 32,4° (meaning that the Sun, at the time that the pictures were taken, was about 57,6° above the imaged Local Mercurian Horizon)
Emission Angle: 4,9°
Sun-Mercury-Messenger (or "Phase") Angle: 32,6°
This picture (which is an Original NASA - MESSENGER Spacecraft color frame published on the NASA - Planetary Photojournal with the ID n. PIA 16625) has been additionally processed and then re-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.MareKromium12/25/12 at 05:152di7: Auguri a tutti!
