What a Pair! (CTX Frame)

This Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on January, 3rd, 2016, shows us an old and Unnamed Impact Crater (visible at the top center of the frame) that has been blanketed by Impact Ejecta which should have come from a younger (and still) Unnamed Impact Crater located to its right (Dx). The older Unnamed Impact Crater appears to contain (---> have) a (relatively easy) visible Central Peak, as well as remnants of a Complex Floor, that has now been covered by "Slumping Material (possibly Dust and Landslides)".


This frame is 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 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.
