In this nice VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 3rd, 2003, and during its 7.248th orbit around the Red Planet, shows an Unnamed Impact Crater that is found within another larger Impact Crater, both located on the Floor of the huge Hadley Crater.

Hadley Crater (which is an ancient Impact Crater found in the Eridania Quadrangle of Mars, centered at 19,5°South Latitude and 203,1° West Longitude. and approx. 119 Km - such as about 73,899 miles - in diameter ) lies to the West of the Channel known as Al-Qahira Vallis, and it is located in the so-called "Transition Zone" existing between the Old Southern Highlands and the Younger Northern Lowlands of Mars.

Hadley Crater has been so named after the British Lawyer and Meteorologist George Hadley (1685 - 1768), whose name was also given to the so-called ‘Hadley Cell’: a Circulation System found in the Earth’s Atmosphere, which transports heat and moisture from the Tropics up to higher Latitudes.

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 19455) 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.
