In this nice VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 27th, 2003, and during its 7.925th orbit around the Red Planet, we can see a really small portion of the highly degraded Inner Rim and quite flat - but partly cratered - Floor of Saheki Crater. Saheki Crater is an ancient Impact Crater located in the Iapygia Quadrangle of Mars, and centered at 21,75° South Latitude and 286.97° West Longitude.

Saheki Crater is about 85 Km (such as approx. 52,785 miles) in diameter and it was so named after Tsuneo Saheki, a Japanese Amateur Astronomer (AD 1916 – AD 1996).

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 19496) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then 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.
