053-Vesta-PIA14312.jpgFeatures of 4- Vesta (Saturated Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)212 visiteCaption NASA:"NASA's Dawn Spacecraft obtained this image of the giant Asteroid 4-Vesta with its framing camera on July, 9, 2011. It was taken from a distance of about 26.000 miles (approx. 41.000 Km). 4-Vesta is also considered a "protoplanet" because it is a large body that almost became a planet. Each pixel in the image corresponds to roughly 2,4 miles (about 3,8 Km).
The Dawn mission to 4-Vesta and 1-Ceres is managed by the Jet Propulsion Laboratory, for NASA's Science Mission Directorate, Washington, D.C. It is a project of the Discovery Program managed by NASA's Marshall Space Flight Center, Huntsville, Ala. UCLA, is responsible for overall Dawn mission science. Orbital Sciences Corporation of Dulles, Va., designed and built the Dawn Spacecraft!".

009-1-Ceres-PIA19884-PCF-LXTT-IPF-1.jpgWhite Unnamed Crater on 1-Ceres (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)63 visiteToday's APOD is an Extra Detail Magnification (or "EDM", for short) of yesterday's Contextual (or "CTX", for short) Frame, taken by the NASA - Dawn Spacecraft that shows us a small White Crater (---> also informally known as "White Spot") that is located in the Northern Hemisphere of the Dwarf Planet named 1-Ceres.
Now, we ask you one (extremely complicated, in fact) question that you, however, should try to answer: why, on 1-Ceres, the huge and deep Impact Craters do not show "White Material" inside them, while, on the other hand, the small and shallow ones (Impact Craters) do? Probably because, but we, as IPF, cannot be sure of this (just like everyone else), the White Material, in the end, does not belong to/comes from the Sub-Surface of 1-Ceres (as we thought, at the beginning), but it belongs to/comes from the Impactors. And you, what do you think?...If you want to share your opinion, please, write us at alphacentauri@intercom.it
The picture 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, was taken on August 21, 2015.
This image (which is a crop taken from an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19884 - Dawn HAMO Image 8) 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.MareKromium
