Volcanic_Regions-Rocky_Outcrops-MGS-01.jpgStreamlined Rocky Outcrops near Olympus Mons (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia) 237 visiteCaption NASA originale:"This MGS-MOC image shows wind-eroded "Streamlined" Rocky Outcrops overlying Lava Flow Surfaces located to the West of Olympus Mons. Outcrops with this appearance are also called Yardangs. Yardangs typically form in Sedimentary Rock or Volcanic Ash that contains some amount of Sand. The weathering of the Rock due to the Aeolian action cause the release of sand-sized particles from the Outcrops and, in time, such a form of erosion slowly shape the rock into the classic, inverted boat hull-like shapes of Yardangs".
Location near: 13,2° North Lat. and 160,1° West Long.

Volcanoes-Ascraeus_Mons-PIA07149-PCF-LXTT-1.jpgAscraeus Mons (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)260 visiteCaption NASA originale:"This red wide angle Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows Ascraeus Mons, the northernmost of the three Tharsis Montes shield volcanoes. Ascraeus Mons is about 460 Km (~286 mi) across and its summit is at an elevation of about 18 km (11 mi) above the "Martian Datum" (or Mars' Ground Zero, such as the elevation designated as 0 km). The center of the Summit Caldera is near 11° North Lat. and 104° West Long.". MareKromium

Craters-Kunowsky_Crater-2004_06-PCF-LXTT.jpgFrost and Wavy Clouds on Kunowsky Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)204 visiteCaption NASA originale:"This red wide angle MGS-MOC image, acquired in March 2004, shows Kunowsky Crater ringed by seasonal Frost. Kunowsky Crater is about 67 Km (~42 mi) in diameter. Wavy Clouds form to the East of the Crater in early Spring as winds circulate from West to East. The Crater is located at about 57,1° North Lat. and 9,7° West Long.". MareKromium

Utopia_Planitia-PIA07839.jpgPolygons in Utopia Planitia (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)232 visiteCaption NASA originale:"This MGS-MOC image shows a typical view of Polygon-cracked and Pitted Surfaces unique to Western Utopia Planitia. No other place on Mars has this appearance. Some Mars scientists have speculated that ground ice may be responsible for these landforms".

Volcanoes-Olympus_Mons-MGS-2003_09-PCF-LXTT-00.jpgOlympus Mons (Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)268 visiteCaption originale: "This is a red camera wide angle view of the Giant Martian Volcano, Olympus Mons, acquired by the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC). The Volcano is large enough to cover much of the state of New Mexico. This view was taken looking West toward the Sunward Limb of the Planet. The limb is the horizon to the left; the dark band is outer space. Sunlight illuminates this scene from the lower left". MareKromium

South_Polar_Regions-SPRC.jpgSublimation at the South Polar Residual Cap (Absolute Natural Colors; credits: Dr Paolo C. Fienga - Lunexit Team)97 visiteCaption NASA:"This MGS-MOC image shows a portion of the South Polar Residual Cap where the effects of Sublimation are apparent.
Over extended periods of time, Sublimation "eats" away at the smoother appearing material (largely composed of frozen CO2), darkening the Scarps and creating the irregularly shaped depressions that are present throughout much of the scene".
