In this nice and clear VIS image, taken by the NASA - Mars Odyssey Orbiter on May, 30h, 2004, and during its 10.910th orbit around the Red Planet, we can see a small part of the North/Western Inner Rim of the famous Schiaparelli Crater.
Schiaparelli Crater is a large, ancient Impact Scar of Mars, some 480 Km (such as about 298,08 miles) wide. It has - let's say obviously - been profoundly modified by billions of years of Erosion and Deposition (inside it) of Particles of Ash and Dust carried, most likely and largely, by Aeolian Actions (---> Wind) and - probably, but in a much lower quantity - even by Water.
For the fictional Astronaut Mark Watney, the descent from the Rim onto the Crater's Floor looks smooth and gradual. But it almost wrecks his Rover Vehicle when he drives into Soft Sediments. His goal (for those who have not yet read the book or watched the movie)? An Automated Rescue Rocket, intended for the next Mars expedition, which stands about 250 Km (such as approx. 155,25 miles) away, on the Southern Part of Schiaparelli's (relatively flat, but still deeply insidious) Floor.

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19799) has been additionally processed, magnified to aid the visibility of the details, extra-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.
