In this VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 2nd, 2015, and during its 58.618th orbit around the Red Planet, you can see (and have to know) that the subtle (---> almost invisible) Paired Surface Fractues - visible at the bottom of the frame - are still part of the Martian Region known as Sirenum Fossae, though this area is hundreds of kilometers away from yesterday's APOD image location.

If you pay special attention to the frame, you might also be able to see a number of Gullies (look at the top of the picture) that are located on the intersection between two Unnamed Impact Crater's Rims.

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 19441) 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.
