The NASA - Dawn Spacecraft obtained this image of the Giant Asteroid 4-Vesta with its Framing Camera on Aug. 26, 2011. This image was taken through the Camera's Clear Filter. The detail in this image shows a steep Scarp (--- Rupes) with Landslides and Vertical Impact Craters located in its Wall. The image has a resolution of about 260 meters per pixel.


This frame (which is an Original NASA - Dawn Spacecraft b/w image published on the NASA - Planetary Photojournal with the ID n. PIA 14716) has been additionally processed and then colorized, according to an informed speculation carried out by Dr Paolo C. Fienga (LXTT-IPF), in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Dawn Spacecraft and then looked outside, towards the Giant Asteroid 4-Vesta), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among others, the existence of different Elements present on the Surface of 4-Vesta, each having a different Albedo (---> Reflectivity) and Chemical Composition.
