North_Polar_Regions-Dunes.jpgNorth Polar Dunes (Original NASA/MGS/MSSS b/w Frame)95 visiteCaption originale:"This MGS-MOC image shows two "Barchan Dunes" in the North Polar Region of Mars. The orientation of the Dunes, with the steep faces pointed toward the South-East, indicates that the winds responsible for their formation blew from the North-West. At the time this image was acquired by MOC, the dunes and surrounding plains were covered by seasonal carbon dioxide frost".
Location near: 73,8° North Lat. an 40,8° West Long.
Image width: ~3 Km (~1,9 mi)
Illumination from: lower left
Season: Northern Winter

North_Polar_Regions-North_Pole.jpgThe North Pole of Mars (Natural Colors; credits: NASA/MGS/MSSS)307 visiteNon ci sono parole sufficienti per descrivere questa meravigliosa immagine ad HD del Polo Nord di Marte ed il volume di dettagli che risultano percepibili è davvero enorme. EccoVi il testo originale di commento al frame:"Spring reached the North Pole of Mars (foto del Maggio 2002) and brought with it the usual dust storms. As the North Polar Cap begins to thaw, a temperature difference occurs between the cold frost region and recently thawed surface, resulting in swirling winds between the adjacent regions. In the above image mosaic from the Mars Global Surveyor spacecraft, the white material is frozen carbon dioxide that covers much of the extreme north. The choppy clouds of at least three dust storms can be identified". Che altro dire???

North_Polar_Regions-The_Erg-MO.jpgThe North Polar Erg (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)54 visiteCaption NASA:"With the surface frost removed by the Summer Sun, different polar textures are exposed. This image contains Polar Dunes and a large region just off the Permanent Polar Cap".

North_Polar_Regions-The_Erg-PIA07282.jpgOutcrops in the North polar Erg (Original NASA/MGS/MSSS b/w Frame)81 visiteCaption NASA originale:"This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image, acquired during Northern Summer in December 2004, shows dark, windblown Sand Dunes in the North Polar Erg: a vast Sea of Sand Dunes that surrounds the North Polar Cap. These landforms are located near 80,3° North Lat. and 144,1° West Long. Light-toned features in the image are exposures of the substrate that underlies the immense Erg. The image covers an area of about 3 Km (1,9 mi) wide and is illuminated by sunlight from the lower left".
Nota Lunexit: le "light-toned features", a nostro avviso, sono soltanto degli affioramenti rocciosi (Rocky Outcrops).

North_Polar_Regions-Unusual_Landscape-MGS-1.jpgIndecipherable North Polar Landscape (Original NASA/MGS/MSSS b/w Frame)55 visiteOriginal caption:"This MGS-MOC image shows a slope on which layered materials are exposed by erosion in the North Polar Region of Mars. Wind streaks are also evident in this Summertime scene.
The layers that make up the material beneath the ice of the North Polar Residual Cap are typically considered to be a mixture of some amount of dust and ice, but the proportions of these constituents are not known".
Location near: 82,6° N; 298,1° W

Season: Northern Summer

Northern_Regions-Mesas-MGS.jpgMesas in Vastitas Borealis (Original NASA/MGS/MSSS b/w frame)54 visiteCaption NASA originale:"This MGS-MOC image shows two mesas on the Northern Plains of Mars. "Mesa" is the Spanish word for "table" and that is a very good description of the two elliptical features captured in this MOC image. In both cases, the Mesa tops and the material beneath them, down to the level of the surrounding, rugged Plain, are remnants of a once more extensive layer (or layers) of material that has been largely eroded away. The circular feature near the center of the larger Mesa is the site of a filled and buried Impact Crater".
Location near: 53,5° North Lat. and 153,5° West Long.
Image width: ~3 Km (~1,9 mi)
Illumination from: lower left
Season: Northern Spring
