This - once again - Bright and unusually-looking Material - nicknamed "Spot 1", by the NASA's Planetary Scientists, and found in and around an Unnamed Impact Crater - is very well visible in this beautiful S-EDM which was obtained from a crop of a Contextual Image, taken by the NASA - Dawn Spacecraft on June 17, 2015. In particular, the East-looking Inner Slopes as well as the South-Western (and, even though in just a small part, the Eastern) Outer Slopes of said Unnamed Impact Crater, seem to be litterally covered by this "White Mineral" whose origin is, of course, still unknown.


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 S-EDM (which is a crop taken out from an EDM obtained  by an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19589) 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.
