In this VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 8, 2013 and during its 50.199nd orbit around the Red Planet, we can see the Eastern Portion of Hydrae Chasma, a deep and almost Circular Depression approximately 50 Km across, situated between Juventae Chasma (to the North) and the large Canyon System known as Valles Marineris (to the South). This Chasma (---> Abyss) has steep Walls, flanked by numerous Landslides and a massive Scarp along its Southern Boundary, just where the Surface has collapsed into the Depression. If you wish to see another image of Hydrae Chasma (taken, in that occasion, by the NASA - Mars Reconnaissance Orbiter), please refer to the APOD of December, 16, 2012.

This frame (which is an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17108) has been additionally processed, magnified, contrast enhanced 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.
