In this beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on June, 9th, 2003, and during its 6.588th orbit around the Red Planet, we can see an old, flat-floored and dusty Unnamed Impact Crater - as well as its (relatively) huge Ejecta Blanket - which is located on the Floor of the much larger Tikhov Crater. Tikhov Crater is an Impact Crater found in the Hellas Quadrangle of Mars and centered at 51,1° South Latitude and 254,3° West Longitude. Tikhov Crater is approx. 111 Km (such as about 68,931 miles) in diameter.


Its name was approved in the AD 1973 by the by the International Astronomical Union (or "IAU", for short) Working Group for Planetary System Nomenclature (or "WGPSN", for short), after Gavriil Adrianovich Tikhov (a Belarussian Astronomer who died in the AD 1960).

This image (which is an Original Mars Odyssey Orbiter falsely colored and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19427) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then re-colorized in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
