Highly Cratered Region on 1-Ceres (EDM)
Highly Cratered Region on 1-Ceres (EDM)

This is an Extra Detail Magnification (or "EDM", for short) that was obtained from yesterday's Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the Framing Camera onboard the NASA - Dawn Spacecraft on January, 2nd, 2016, which showed us, among other things, several Unnamed Impact Craters superimposed upon one another. The low Sun angle enhanced the Topography of this densely Cratered Region. One (truly) unusually-looking, (relatively) small and Complex Unnamed Impact Crater (the one visible in this EDM, at about 9 o'clock of the picture) seems to have some sort of a "Wall" inside it that, in fact, splits the Crater's Floor in two parts: one that is illuminated, and one that is in the darkness. 

The Original Image was centered at approximately 78° South Latitude and 171° East Longitude. The original photo was taken during the NASA - Dawn Spacecraft's Low-Altitude Mapping Orbit (or "LAMO", for short) and from a distance of approx. 242 miles (such as about 389,460 Km) as to the Surface, with a resolution of roughly 118 feet (such as about 35,9664 meters) per pixel.


This image (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 20313 - DAWN LAMO Image n. 23) 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.
