MarsColors01-Viking.jpgVolcanic Outgassing from Arsia Mons? (CTX Frame)124 visiteDURING THE FINAL APPROACH to Mars, just before going into orbit, the Viking Orbiters took a series of pictures of the Planet with different color filters. As the Planet rotated, different parts were photographed until almost the entire surface was covered.
The pictures taken with the various filters were then compared, and the color at each point on the surface was determined by means of a variety of sophisticated computer processing techniques. The results are displayed in frame (2) as Mercator Maps of the Equatorial Regions (the approach trajectory prevented good visibility of the Polar Regions, and they are not shown).
Although Mars has very distinct light and dark areas, differences in color are quite subtle. The appearance of the Planet is dominated by variations in brightness or albedo that cause the classical markings known from telescopic observations.
The color of the surface is a fairly uniform rusty brown and differences are so small that they can barely be seen.
NOTA Lunexit: nel frame in questione si vede BENISSIMO (anche se nessuno - neppure noi, sino a circa 5 minuti fa (ore 18:00 dell'AD 2011, Novembre, 6 - sembra averci MAI fatto caso) una "fumata vulcanica" di notevolissime dimensioni che potrebbe provenire sempre da Arsia Mons (diciamo che SEMBRA Arsia, ma non possiamo esserne sicuri al 100%). A questo punto, la recente "fumata" di Arsia (ripresa dalla Sonda ESA Mars Express) a noi non pare più il solo e semplice prodotto di una svista o di una interpretazione eccessivamente immaginifica dei dati. Molto probabilmente, anche se potrebbe trattarsi di mero vulcanismo residuale (ossìa di fenomenologie, si, vulcaniche, ma del tutto estemporanee e di entità minima), i Grandi Vulcani di Tharsis non sono ancora - e comunque non del tutto... - morti. E su questga riflessione, ci si dovrebbe fermare per un pò...11/06/11 at 16:09MareKromium: NOTA: nel frame in questione si vede BENISSIMO (an...

vo1_783a42.jpgMars, according to Viking 1 Orbiter - Martian Cyclone56 visiteThis Viking 1 Orbiter image shows a "Low Pressure Cell" near the North Pole of Mars. This Cyclonic Storm is related to Mars' Polar Front, the boundary between the cold polar air and the warmer air to the south.
These clouds are low in the Atmosphere and most likely composed of water ice.
This image was taken in Martian Northern Mid-Summer at 6:55 MLT. The image is approx. 1150 Km across and north is at 11:30.10/29/10 at 17:01andreagg: lo avevo preso come metro di paragone anch'io ...
