This fascinating (but relatively common, in a way...) Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on February, 22nd, 2016, shows us some highly Craterd Terrain that is found within (---> on the Floor) of the large Chaminuka Crater.


Chaminuka Crater was so named after the Spirit who provides rains during times of drought, according to the legends of the Shona People of Zimbabwe. Chaminuka Crater measures about 76 miles (such as approx. 122,30984 Km) in diameter and is located in the Southern Hemisphere of this truly "strange and intriguing" Celestial Body.


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 image (which is an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20568 - DAWN LAMO Image n. 73) 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.
