What a Pair! (EDM)
What a Pair! (EDM)

This is an Extra Detail Magnification (or "EDM", for short) obtained from yesterday's Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on January, 3rd, 2016, that showed us an old and Unnamed Impact Crater (visible at the top left - Sx - of the frame) that has been blanketed by Impact Ejecta which should have come from a younger, (and also) Unnamed Impact Crater with really steep and clean Slopes located to its right (Dx). The older Unnamed Impact Crater appears to contain (---> have) a (still barely) visible Central Peak, as well as remnants of a Complex Floor, that has now been covered by "Slumping Material (possibly Dust and Landslides)".


The Original Frame was centered at about 10,5° North Latitude and 155,7° East Longitude. The NASA - Dawn Spacecraft captured the scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 227 miles (such as about 365,320 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 112 feet (i.e. about 34,1376 meters) per pixel (---> Picture Element).


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 20383 - DAWN LAMO Image n. 29) 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.
