This "dark" and, just as usual, very mysterious and suggestive Extra Detail Magnification ("EDM") has been obtained from a Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on March, 8th, 2016, which showed us the complex, uneven and extremely unusually-looking Attis Crater, which measures about 14 miles (such as roughly 22,53 Km) in diameter. The long shadows visible in (and around) the Crater reflect Attis's truly far-Southern location. Attis Crater is centered at about 73° South Latitude and 257° East Longitude. What is the origin of the almost Linear 4 Cracks which characterize the Cetral Portion of the Floor of Attis Crater? Non one knowns for sure. Yet...


The NASA - Dawn Spacecraft captured the scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 240 miles (such as about 386,2416 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 120 feet (i.e. about 36,576 meters) per pixel (---> Picture Element).


This picture (which is a crop obtained from an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20672 - DAWN LAMO Image n. 92) has been additionally processed, extra-magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized (according to an educated guess carried out by Dr Paolo C. Fienga-LXTT-IPF) in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Dawn Spacecraft and then looked ahead, towards the Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
