This really beautiful and dramatic image taken by the NASA - MESSENGER Spacecraft shows us the Central Peak of the Stieglitz Impact Crater, which is located high on Mercury's Northern Hemisphere. The fresh appearance of its Ejecta Deposit suggests that Stieglitz is a relatively young Crater. Intriguingly, Stieglitz also hosts some significant amounts of Radar-Bright Materials whose origin and composition is, so far, unknown. Date acquired: August, 27th, 2012 This picture (which is an Original NASA - MESSENGER Spacecraft b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 16420) has been additionally processed and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - MESSENGER Spacecraft and then looked down, towards the Surface of Mercury), 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 other things, the existence of different Elements (Minerals) present on the Surface of Mercury, each having a different Albedo (---> Reflectivity) and Chemical Composition. |
