North_Polar_Features-Chasma_Boreale-PIA07195-00-PCF-LXTT.jpgFeatures of Chasma Boreale (Original NASA/MGS/MSSS b/w Frame) 97 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)106 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)263 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!

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) 275 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".
