A Mountain on 1-Ceres, and something more...

Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA and Dr Paolo C. Fienga for the additional process. and color.

A large Mountain - about 3 miles (such as approx. 4,82802 Km) high, surrounded by (relatively) smooth Terrain - can be seen in this fascinating picture taken by the NASA - Dawn Spacecraft. North on 1-Ceres is towards the upper left (Sx) of the frame.


Also clearly visible here, is a new White Spot (located in the lower portion of the frame), a relatively recent (we believe, as IPFOblong-shaped Impact Crater whose Inner Slopes are marked by whitish Flows, and - last but not least - a small area - found in and out, and oriented to the East of a small Impact Crater - which seems to be covered by a "flow" of White Material (coming from the Crater itself) whose origin is still unknown (watch, once again, towards the upper left - Sx - corner of the frame).


Just out of curiosity, this specific frame is just one among the first snapshots coming from Dawn's second Mapping Orbit of 1-Ceres, which is carried out from an altitude of approx. 2700 miles (such as about 4345,218 Km).  The Resolution here is roughly 1400 feet (such as approx. 426,72 meters) per pixel.


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 19586 - Dawn Survey Orbit Image 18) 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 Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
