North_Polar_Features-Chasma_Boreale-PIA07195-00-PCF-LXTT.jpgFeatures of Chasma Boreale (Original NASA/MGS/MSSS b/w Frame) 94 visiteCaption NASA originale:"This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark Sand Dunes in the North Polar Region of Mars. They are streaming away (toward the left) from a low escarpment at the edge of an outlier of Polar Water Ice (the bright area on the right). The picture covers an area about 3 Km (1.9 mi) wide and is located near 80,7° North Lat. and 80,2° West Long.. Sunlight illuminates the scene from the lower left".

Souhern_Emisphere.jpgThe Southern Hemisphere of Mars (Natural Colors; credits: NASA/MGS/MSSS)102 visiteCaption NASA:"The wide angle camera view of Mars shown here was obtained by the Mars Global Surveyor Mars Orbiter Camera in late July 1999, about 1 week before the start of southern Spring. The frosty, retreating south polar cap (white) is seen in the lower quarter of the image and wisps of dust storm clouds (grayish-orange in this view) occur just above the cap at the lower left. The southernmost of the large Tharsis volcanoes, Arsia Mons, is seen at the upper left. Arsia Mons is about 350 Km across".

Phobos_from_MGS-001.jpgPhobos from Mars Global Surveyor (2)260 visiteTra le idee che la NASA aveva in mente c'era anche quella di inviare una Sonda proprio su Phobos, onde studiarlo meglio ed eventualmente atterrarci sopra.
L'idea di uno studio maggiormente approfondito di questo corpo celeste è rimasta, ma le possibilità di un atterraggio sono sensibilmente diminuite da quando si è scoperto (grazie alla Sonda Mars Global Surveyor ed alle immagini scattate in infrarosso) che l'intera superficie di Phobos è ricoperta da uno strato uniforme di polvere spesso circa 1 metro!

Volcanoes-The_FootPrint_Volcano-A-MGS-PCF-LXTT-IPF.jpgThe "Footprint" Volcano (Absolute Natural Colors; credits for the additional process. and color.: Drr Don P. Mitchell and Paolo C. Fienga - Lunexit Team)85 visiteThis NASA - Mars Global Surveyor (MGS) - Mars Orbiter Camera (MOC) High Resolution image, acquired on the date of July, 13, 2003, shows a small, Dust-covered and so far - officially - Unnamed Volcano (note: the nickname "Footprint" has been given to this Surface Feature by the Researchers of the Italian Planetary Foundation) that is located on the Volcanic Plains to the East of the Giant Martian Volcano, Pavonis Mons.
It is interesting to notice that the Floor of the Caldera - such as the elliptical depression visible at the Summit of the Volcano - has a few windblown Ripples on it. The Ripples and the extremely thick Dust Mantle, together with a number of small Impact Craters located on its Surface, are signs which indicate that the "Footprint" Volcano erupted a VERY long time ago, and that there has been no more activity in (geologically speaking) recent times. In addition to the above, we also wish to underline that, while the Surface surrounding the Footprint Volcano has kept, despite the eons of volcanic idleness, a dark gray color (such as the typical colors of Lava, once is cooled off, and Volcanic Ashes), the Land that is farther away from the Volcano has maintained (or maybe re-gained?) the typical brown-orange color which characterizes most of the Equatorial and Peri-Equatorial Surface of Mars. This image covers an area approx. 3 by 6,8 Km wide (such as approx. 1,9 by 4,2 miles). The Footprint Volcano is located near 1,6° South Lat. and 105,7° West Long.; the Sunlight illuminates the scene from the South.
The frame has been colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Global Surveyor 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.MareKromium

Hills-Zephyria_Region-PIA07859-00.jpgFlow Features and Hills in Zephyria Planum (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 272 visiteCaption NASA originale:"This MGS-MOC image shows a Plain covered by Flow Material that surrounded and banked against 3 older, rounded Hills in the Zephyria Region. Although some investigators have proposed that the Flows covering Plains in this Region are the remains of an ice-covered lake, others have found considerable evidence, including small Volcanoes, to suggest that the Flows are Volcanic. The textures on these Flows resemble that of some of the Lava Flows in the Tharsis Region of Mars".
