Craters-Kunowsky_Crater-2004_06.jpgFrost and Wavy Clouds on Kunowsky Crater (Original NASA/MGS/MSSS b/w Frame)102 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.".

Dunes-PIA07152-00.jpgDark Dunes and Yardangs inside Herschel Crater (Original NASA/MGS/MSSS b/w Frame)100 visiteImmagine ripresa dal Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) che ci mostra Dune di colore scuro, scolpite dal vento, che giacciono sul fondo del Cratere Herschel. La superficie di queste Dune sembra caratterizzarsi per il fatto che ci appaiono - anche da una notevole distanza... - consistenti fessure scavate al loro interno. Questo sta a significare che la sabbia che le forma NON semplicemente "accatastata" (ma, granuloscopicamente parlando, "libera"), cos come accade per la maggior parte delle Dune Terrestri! Questo fenomeno ci dice che la sabbia di queste Dune Marziane "cementata e compatta", simile a roccia (fragile, ma pur sempre roccia), e l'azione costante dei venti, nel tempo, ha creato, su queste sabbie "indurite", delle particolari "aree erose" che sono conosciute come Yardangs. L'immagine copre un'area di circa 3 Km (1,9 miglia) la quale si trova vicino ai 15,6 di Latitudine Sud ed ai 229,0 di Longitudine Ovest. Il Sole illumina la scena dalla Sn, in alto.

Volcanoes-The_FootPrint_Volcano-D.jpgThe "Footprint" Volcano (Original NASA/MGS/MSSS b/w Frame)100 visiteCaption NASA originale:"This MGS-MOC HR image, acquired 13 July 2003, shows a small, Dust-covered Volcano on the Plains located to the East of Pavonis Mons.
The Floor of the Caldera - such as the elliptical depression at the Summit of the Volcano - has a few windblown Ripples on it. The Ripples and thick Dust Mantle, together with the small impact craters on its Surface, indicate that the Volcano erupted some time ago, but there has been no activity at this Volcano in geologically recent times. This image covers an area approx. 3 Km wide by 6,8 Km (approx. 1,9 mi by 4,2 mi). The Volcano is located near 1,6° South Lat. and 105,7° West Long.; sunlight illuminates the scene from the left".
Nota Lunexit: il nome "Footprint" è stato convenzionalmente attribuito a questo rilievo da Lunar Explorer Italia.

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)100 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

Craters-Galle_Crater-Happy_Face_Crater-2003_05_15_M2300366.jpgGalle Crater (Natural Colors; credits: NASA/MGS/MSSS)99 visiteCaption NASA originale:"The 2 pictures shown here are taken from the same daily global image mosaic (the only difference is that each was processed slightly differently). The pictures show Galle Crater, informally known as "Happy Face," as it appeared in early Southern Winter. The white-ish gray surfaces are coated with wintertime carbon dioxide frost. The pattern of frost distribution gives the appearance that "Happy Face" has opened its mouth. Galle Crater is located on the east rim of Argyre Planitia at 51S, 31W. Sunlight illuminates the scene from the upper left. Galle Crater is about 230 Km (143 mi) across".

Volcanoes-Pavonis_Mons.jpgPavonis Mons (Darkened Natural Colors; credits: NASA/MGS/MSSS)97 visiteCaption NASA originale:"This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide angle color composite image, obtained in December 2003, shows the middle of the three Tharsis Montes, Pavonis Mons.
This is a broad shield volcano -similar to the volcanoes of Hawaii - located on the Martian equator at 113° W.
The volcano summit is near 14 Km (~8.7 mi) above the Martian Datum (0 elevation); the central caldera (crater near center of image) is about 45 Km (~28 mi.) across and about 4.5 Km (~2.8 mi.) deep.
Sunlight illuminates the scene from the lower left".
