In this VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 26th, 2014, and during its 54.853rd orbit around the Red Planet, we can see a portion of a huge Dunefield that covers most part of the Floor of Lyot Crater: a large (approx. 236 Km - such as about 146,556 miles - in diameter) Impact Crater located in the Northern Hemisphere's Martian Region known as Vastitas Borealis. Several Hills are easy to spot al over this area, and one of them, visible toward the right (Dx) upper margin of the frame, shows deep Gullies on its whitish North/West-facing Slopes; last, but not least, on the upper portion of the frame, right in the middle of a relatively flat (and Dust-free) area, a medium-sized Impact Crater with (an irregularly-shaped) Pedestal can also be seen. Latitude (centered): 50,2638° North 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 18544 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 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. |
