Ancient and Unnamed Impact Crater on 1-Ceres (CTX Frame)
Ancient and Unnamed Impact Crater on 1-Ceres (CTX Frame)

This beautiful Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on January, 2nd, 2016, shows us an extremely ancient and Unnamed Impact Crater which displays a (relatively, considering the very high amount of Impacts) flattened Floor and a low, small and slightly (VERY slightly, as NASA says...) "rounded", Central Peak.


The frame is centered at about 43,8° South Latitude and 122,6° East Longitude. The NASA - Dawn Spacecraft captured the scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 234 miles (such as about 376,585 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 115 feet (i.e. about 35,052 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 20310 - DAWN LAMO Image n. 26) 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.
