Venusian_Atmosphere-ORB410_411_tot_H1.jpgThe Venusian Atmosphere under the Messenger56 visiteCaption ESA:"The images in this panel were obtained by the VIRTIS imaging spectrometer on board Venus Express on 5 and 6 June 2007, before and after MESSENGER’s closest approach to the Planet. These panels from VIRTIS provide a night-side view of the same Region that Messenger flew over and imaged.
The images where obtained at 1,7 micrometres, revealing atmospheric details down to an altitude of 50 Km from the surface".MareKromium

ZZ-ZZ-TheDunes-K12.jpgDunes (natural colors - elab. Keith Laney)56 visiteUna bellissima interpretazione delle dune di Endurance operata dal nostro buon Amico (ed ottimo Artista!) Keith Laney. Solo una precisazione: se i colori delle dune fangose di Endurance fossero davvero questi, allora potremmo TRANQUILLAMENTE parlare di una nuova (e strabiliante) evidenza oggettiva relativa alle modalità (peculiari, ma fisicamente comprensibili) attraverso le quali gli Idrocarburi affiorano su Marte.
Attenzione però: a nostro avviso questa elaborazione in "Natural Colors" è bella e suggestiva, MA NON REALISTICA.
La nostra conclusione è basata sull'applicazione del medesimo tipo di colorizzazione adottato bda Keith Laney sull'intera area di Endurance e non soltanto sulle dunette fangose che caratterizzano il fondo del cratere.
Ebbene, adottando una simile tecnica di colorizzazione, Endurance e tutta la regione a cui accede, dovrebbero presentarsi di color grigio/verde, con riflessi argento. Certo, un'ipotesi suggestiva ed un paesaggio - a quel punto - "Alieno ed Esotico" alla ennesima potenza ma...Io credo che la nostra interpretazione (frame che segue) sia, sebbene meno immaginosa e suggestiva, decisamente più verosimile.
E poi...Ai Posteri (l'ardua) Sentenza!MareKromium

PSP_004820_0940_RED_browse.jpgFingerprint Terrain with Sawtooth Patterns in the South Polar Ice Cap (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)56 visiteThis image shows a portion of the South Polar Ice Cap. The ice you see here is frozen CO2 rather than the frozen water you are used to here on Earth.
Even on Mars, where the temperatures are much lower than on Earth, CO2 ice is a volatile substance. As it is so unstable, large amounts can sublimate very quickly when heated. In this ice cap we can see icy features shrink in size by several meters per year as the ice that makes them up is removed by solar heating. Usually these icy features are almost circular as you get equal amounts of Sunlight from every direction when you are at the Pole.
However, in this location something strange has happened. Instead of the usual circular features we see features that are decidedly linear in shape. These sets of linear features have been dubbed "fingerprint terrain" by Planetary Scientists. They are seen in several locations in this ice cap and usually have a wavelength close to 90 mt (295 feet). It's hard to understand why linear features would form in this sort of environment by sublimation of ice alone.
It is possible that these features are formed instead by atmospheric processes. Either the features are sand dunes covered by a thin covering of frost or they might be made up of loose ice crystals that saltate like sand grains and have collected into ripples.
It would be a huge surprise to find sand dunes in this location, just as you wouldn't expect to see sand dunes on top of the Greenland ice sheet on Earth. To confirm that they are made of CO2 ice, HiRISE will image this location again at the end of the year and compare it to this image to look for changes.
Icy features should show large changes, but sand dunes move much more slowly. MareKromium
