Fienga - Lunexit Team)53 visiteCaption NASA:"Autumn has begun in the Southern Hemisphere of Mars. As the Sun retreats northward frost will begin to accumulate. The frost-free Floor of this Unnamed Crater, with it's intricate texture, will soon be hidden. Due to Mars' orbit, the seasons are twice as long as on Earth - so it will be a full earthyear before this Crater Floor is exposed again".MareKromium

ESP_013557_1245_RED_abrowse-01.jpgThe "Argyre Lineae" and the "Lineae" seen on the Jovian moon "Europa": a comparison (CTX-Frame - image-mosaic by Lunexit)62 visitePer il momento, il nostro parallelo è solo un azzardo, giustificato - si fa per dire... - dalla notevole somiglianza esistente fra le linee che caratterizzano la Superficie della Luna Gioviana "Europa" (pensate, ad esempio, alla "Minos Linea" - in basso a Dx - che la NASA stessa ritiene essere la "Prova Geologica" dell'esistenza di un Oceano Sotterraneo - liquido! - situato ad un centinaio di Km di profondità) e queste "linee" che caratterizzano il Terreno Marziano intorno alla Latitudine 55° Sud. e 32° Est - Regione della Pianura di Argyre, a circa 2° di Lat. di distanza dal Distretto Montuoso di Charitum (il quale costituisce, nella sua interezza, il margine - Rim - Sud del Bacino di Argyre).
Certo, la NASA dice che queste "Linee Marziane" sono i soliti segni lasciati dal transito dei Dust Devils ma, se osservate con attenzione, potreste notare che esistono - invece - delle nette ed indubitabili differenze fra queste "Linee di Argyre" ed i DD-Tracks.
(nota: la definizione di questi segni della Superficie Marziana come "Argyre Lineae" è stata operata da Lunexit e non dalla NASA)MareKromium

Islands.jpgThe Islands of Mars (Original NASA-2001 Mars Odyssey Orbiter b/w Frame)55 visiteNew HR images of mid-latitude Mars are revealing glacier-formed landscapes far from the Martian Poles, says a leading Mars Researcher.
Conspicuous trains of debris in valleys, arcs of debris on steep slopes and other features far from the polar ice caps bear striking similarities to glacial landscapes of Earth, says Brown University's James Head III. When combined with the latest climate models and orbital calculation for Mars, the geological features make a compelling case for Mars having ongoing climate shifts that allow ice to leave the poles and accumulate at lower latitudes.
"The exciting thing is a real convergence of these things, said Head, who will present the latest Mars climate discoveries on Sunday, 16 October, at the Annual Meeting of the Geological Society of America in Salt Lake City (Utah). "For decades people have been saying that deposits at mid and equatorial latitudes look like they are ice-created, said Head. But without better images, elevation data and some way of explaining it, ice outside of Mars' polar regions was a hard sell.
Now high-resolution images from the Mars Odyssey spacecraft's Thermal Emission Imaging System combined with images from the Mars Global Surveyor spacecraft's Mars Orbiter Camera and Mars Orbiter Laser Altimeter can be compared directly with glacier features in mountain and polar regions of Earth. The likenesses are hard to ignore.
For instance, consider what Head calls "lineated valley fill." These are lines of debris on valley floors that run downhill and parallel to the valley walls, as if they mark some sort of past flow. The same sorts of lines of debris are seen in aerial images of Earth glaciers. The difference is that on Mars the water ice sublimes away (goes directly from solid ice to gas, without any liquid phase between) and leaves the debris lines intact. On Earth the lines of debris are usually washed away as a glacier melts.
