This is certainly not the first time that we can take a look at the Limb of Mercury and, just as usual, we have to underline that these kind of images never fail to showcase the Geological Diversities of the Innermost Planet of the Solar System. This time, something fills the scene with "terror" and that is, to be clear and precise, the "Terror Rupes", such as the long, Cliff-like Landform visible almost at (better yet to say "near"...) the center of the scene. Terror Rupes is one of Mercury's most prominent Lobate Scarps, and it was so named after the HMS (---> Her Majesty's Ship) Terror: an eighteenth-century warship that, later, participated in Scientific Polar Explorations. Date acquired: February, 4th, 2012 This picture (which is an Original NASA - MESSENGER Spacecraft's b/w and NON-Map-Projected image published on the NASA - Planetary Photojournal with the ID n. PIA 17881) has been additionally processed, contrast enhanced, Gamma corrected, magnified to aid the visibility of the details 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 outside, towards the Southern Limb 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. |
