ZZ-Mercury-Limb-PIA14551-pcf-lxtt.jpgMercurian Limb (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)131 visiteThe Rays apparent in this spectacular Limb image of Mercury come from Debussy, the sharp Crater near the Terminator. This dominant Crater on Mercury was also a part of MESSENGER's historic image of Mercury- the first image ever to be taken from a spacecraft in orbit about this Planet. Readers may also notice a streak in the blackness of space in the top left corner of the image. This artifact was produced by a Cosmic Ray hitting the camera's CCD detector while the image was being collected.
This image was acquired as part of MDIS's Limb imaging campaign. Once per week, MDIS captures images of Mercury's Limb, with an emphasis on imaging the Southern Hemisphere's Limb. These Limb images provide information about Mercury's shape and complement measurements of topography made by the Mercury Laser Altimeter (MLA) of Mercury's Northern Hemisphere.

ZZ-Mercury-Global_View_of_the_Surface-PIA14399-PCF-LXTT.jpgLow Reflectance Material and Crater Rays (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)206 visiteThis image highlights some of the color features present on Mercury's Surface, such as Low Reflectance Material (LRM) and Crater Rays. Visible in the top left quadrant of this image is the named crater Moody, which has a prominent yellow-orange color on its Floor in this enhanced color image.
This image was acquired as part of MDIS's color base map. The color base map is composed of WAC images taken through eight different narrow-band color filters and will cover more than 90% of Mercury's Surface with an average resolution of 1 Km/pixel (0,6 miles/pixel). The highest-quality color images are obtained for Mercury's surface when both the Spacecraft and the Sun are overhead, so these images typically are taken with viewing conditions of low incidence and emission angles.

ZZ-Mercury-Craters-Ives_Crater-PIA14360-PCF-LXTT.jpgIves Crater (Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)133 visiteCaption NASA:"In this image, one is immediately drawn to the Rayed Crater in the upper right. Ives Crater, named in 1979 after American composer Charles Edward Ives, is smaller than many Unnamed Craters visible in this image, but it is younger and therefore brighter than its surrounding Terrain".

ZZ-Craters-Mercury-Secondary_Craters_Field-PIA14379.jpgSecondary Crater-Chains or Signs of multiple and simultaneous Cometary Impacts? (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)158 visiteCaption NASA:"This view captured by MESSENGER's wide angle camera (WAC) shows many Secondary Crater-Chains that originated from a Primary Impact Crater located outside this image, to the West. The Secondary Crater-Chains are formed as the Parent Crater-forming event launches Ejecta into the surrounding area. The chunks of Ejecta dig out their own craters which sometimes overlap to form a long valley-like depression. These features are striking though not uncommon on Mercury's battered Surface. Some other examples of Secondary Craters can be found at Abedin Crater".

ZZ-Mercury-Craters-Cervantes_Crater-PIA14251-PCF-LXTT.jpgPortion of the Rim of Cervantes Crater (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)151 visiteThe Rim of the Double-Ring Basin Cervantes cuts through the middle of this NAC image. Cervantes has a diameter of about 213 Km and was named in honor of the Spanish novelist, playwright, and poet Miguel de Cervantes (1547-1616), best known for his novel Don Quixote.
This image was acquired as part of MDIS's High-Resolution Surface Morphology Base Map. The Surface Morphology Base Map will cover more than 90% of Mercury's Surface with an average resolution of 250 meters/pixel (0,16 miles/pixel or 820 feet/pixel). Images acquired for the Surface Morphology Base Map typically have off-vertical Sun Angles (i.e.: high Solar Incidence Angles) and visible shadows so as to reveal clearly the topographic form of geologic features. On March 17, 2011 (March 18, 2011, UTC), MESSENGER became the first Spacecraft ever to orbit the planet Mercury. The mission is currently in its commissioning phase, during which Spacecraft and instrument performance are verified through a series of specially designed checkout activities. In the course of the one-year primary mission, the Spacecraft's seven scientific instruments and radio science investigation will unravel the history and evolution of the Solar System's innermost Planet.

ZZ-Mercury-Limb-PIA14250-PCF-LXTT-1.jpgCrescent Mercury (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)74 visiteMercury forms a beautiful crescent shape in this image, acquired as the MESSENGER Spacecraft was high above Mercury's Southern Hemisphere. On the left side is the Terminator, dividing the day from night. On the right side is the sunlit Limb, separating Mercury from the darkness of (the Inner) Space.
This image was acquired as part of MDIS's limb imaging campaign. Once per week, MDIS captures images of Mercury's Limb, with an emphasis on imaging the Southern Hemisphere Limb.

ZZ-Mercury-Z1.jpgThe "Face" of Mercury (Natural Colors; credits for the additional process. and color.: NASA/JHU APL/CIW)192 visiteCaption NASA:"On March 17, 2011, the MESSENGER Spacecraft became the first to orbit Mercury, the Solar System's Innermost Planet. This is its first processed color image since entering Mercury orbit. Larger, denser, and with almost twice the Surface Gravity of Earth's moon, Mercury still looks moon-like at first glance.
But in this view its Terrain shows light blue and brown areas near Craters and long bright rays of material streaking the Surface. The prominent bright ray crater Debussy at the upper right is approx. 80 Km (49,68 miles) in diameter. Terrain toward the bottom of the historic image extends to Mercury's South Pole and includes a region not previously imaged from Space".MareKromium
