The Southern Hemisphere of 1-Ceres

As we have already said in a very recent past, also this specific frame - which shows a large portion of the Southern Hemisphere of the so-called "Dwarf Planet" known as 1-Ceres - is just one among the first snapshots coming from Dawn's second Mapping Orbit of 1-Ceres; this picture has been taken from an altitude of approx. 2700 miles (such as about 4345,218 Km). Even in this case, the Resolution is roughly 1400 feet (such as approx. 426,72 meters) per pixel.


Huge and small Unnamed Impact Craters (both Simple and Complex), jointly with a number of (tiny) "White Spots" and "White Areas" characterize the whole scene. All that said, 1-Ceres is still, to us, an almost completely unknown Celestial Body but, in the future, we might see, know and, maybe, understand something more about its past and, why not, its present....


The 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 19624 - Dawn Survey Orbit Image 48) has been additionally processed, 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 Limb and Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
