This interesting Contextual (or "CTX", for short) Frame, taken by the NASA - Dawn Spacecraft on September, 15, 2015, shows us several intriguing Surface Features which are all located of the Dwarf Planet known as 1-Ceres.


First of all, there is one truly deep Crack (look at the center of the frame) that almost cuts the picture in one half; second, you can see some funny-looking Striations (center right - Dx - of the frame) of unknown (let's say: unexplainable, for now) origin, a few Crater-Chains (the bigger one located beneath the large Crack that we have already mentioned hereabove) and many Unnamed Impact Craters (where the biggest - and most Complex one - is visible to the left - Sx - side of the picture).


The photo was taken from an altitude of approx. 915 miles (such as about 1472,5461 Km) from the Surface, with a resolution of roughly 450 feet (such as about 137,16 meters) per pixel.


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 19972 - Dawn HAMO Image 34) 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.
