Psp_001401_1850_red-1.jpgThe "Bridges" of Arabia Terra (1) extra-detail mgnf78 visiteUn detail-mgnf che ci mostra con sconcertante chiarezza l'impossibilità che questi rilievi sìano il prodotto di azioni eoliche (anche complesse).

Alcuni Ricercatori suggeriscono un'origine artificiale per questi "ponti!" (o "tubi"); noi supponiamo, invece, una loro origine naturale, ma da investigarsi in un'ottica non geologica (o almeno NON SOLO geologica).

Psp_001401_1850_red-3.jpgThe "Bridges" of Arabia Terra (2) extra-detail mgnf53 visiteC'è poco da commentare in questo dettaglio: osservate Voi stessi la conformazione, la configurazione e la posizione di questi indecifrabili rilievi e poi provate a maturare una opinione al riguardo.
A nostro avviso, NON siamo davanti ad image-artifacts nè a rilievi soggetti ad una forma di distorsione dell'immagine dovuta al tipo di angolo visuale adottato da MRO (e quindi rilievi "regolari" che appaiono "distorti" in seguito ad un effetto ottico).

La Verità, al momento, è che siamo in presenza di rilievi peculiari di Marte e, di fatto, non solo inesplicabili, ma anche totalmente ignorati (almeno in via "ufficiale") dalle maggiori Agenzie Spaziali.

Psp_001481_2410_red-00.jpgEolian and Periglacial Activities in Vastitas Borealis (DD Tracks and Polygons)54 visiteThis image shows a region of approximately 7 x 7 km (4.4-by-4.4 miles) located in Vastitas Borealis, part of the Northern Plains.

The surface imaged is relatively young, as indicated by the lack of recent impact craters.
Eolian and Periglacial activity seem to be the dominant geological processes at work, as shown by numerous crisscrossing DD Tracks and ubiquitous polygonal features, respectively.

Dust Devils form when the sun warms up the air near a flat, dry surface. Warm air then rises quickly through the cooler air above and starts spinning, causing a forward motion. The spinning, forward-moving cell may pick up dust and sand as it advances, thus leaving behind a "clean" track. We infer from this image that a thin veneer of light-colored particles of dust and/or fine-grained sand cover relatively darker materials, apparent in the dust devil tracks.

The tracks pictured in this image are in many cases more than 30 mt (27 yards) wide and over 4 Km (2,5 miles) long, surpassing the dimensions of average terrestrial DD tracks.

Psp_001481_2410_red-01.jpgEolian and Periglacial Activities in Vastitas Borealis (polygons)53 visiteThe polygons shown in this image's subset, which covers approximately 400 x 250 mt (350 x 225 yards), are in the order of 10 mt (0.9 yards) across; in some cases they are delimited by aligned rocks. Similar features in both shape and scale are found in Terrestrial Periglacial Regions such as Antarctica, where ice is present at or near the surface.

Antarctica's polygons and rock alignments are produced by repeated expansion and contraction of the soil-ice mixture due to seasonal temperature oscillations; dry soil falling into the cracks form sand wedges and amplify this effect. This results in polygonal networks of stress fractures and in the resurfacing and sorting of rocks along these fractures.
