Craters-Unnamed_Concentric_Craters-M2100005.jpgConcentric Craters (Original NASA/MGS/MSSS b/w Frame)77 visiteCrateri all'interno di crateri o 'crateri concentrici': si tratta di un fenomeno decisamente raro ed inusuale, ma non (ovviamente) impossibile. Questa Stranezza Marziana non la annoveriamo fra le Anomalie in senso stretto, bens fra le - semplici - "rarit" che la Natura capace di creare.

Craters-Unnamed_Crater-Layered_Outcrop-Thaumasia_Region-00.jpgLayered Rocky Outcrops (Original NASA/MGS/MSSS b/w Frame)67 visiteCaption NASA originale:"This MGS-MOC image shows light-toned, layered rock outcrops in the central pit of an impact crater in the Thaumasia Planum Region of Mars. The outcrops were tilted and broken-up by the extreme energy of the impact that formed the crater in which they occur. These are layers of rock that were brought up by the impact from horizontal beds that lie below the floor of the crater".
Location near: 21,7 South Lat. and 69,4 West Long.
Image width: ~3 Km (~1,9 mi)
Illumination from: upper left
Season: Southern Summer
Nota: difficile pensare, per spiegare i rilievi catturati in questo frame, ad una costruzione logica pi improbabile di quella proposta dalla NASA...

Craters-Unnamed_Crater-MGS-PIA06877.jpgUnnamed Crater in Lycus Sulci (Original NASA/MGS/MSSS b/w Frame)103 visiteUn Cratere da impatto Senza Nome giace nell'area immediatamente ad Ovest di Lycus Sulci ed a Nord-Ovest del Monte Olympus. Spettacolare il livello di dettaglio raggiunto nella ripresa delle pareti del Cratere che, nella sua interezza, copre un'area di circa 3 Km quadrati.

Craters-Unnamed_Crater-PIA06699-PCF-LXTT.jpgDark Slope Streaks (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)143 visiteCaption NASA:"Dark Slope Streaks are a common feature on the Slopes thickly-mantled by Dust in the Tharsis, Arabia, and Western Amazonis Planitia egions of Mars. Less common are light-toned Slope Streaks, which often occur in the same area as Dark Streaks. They are most common in Arabia Terra, and some are shown in this MGS image. Slope Streaks are probably the result of sudden Avalanches of extremely dry Dust. The behavior of the avalanching dust is somewhat fluid-like and it is a phenomenon often observed during the Martian year.

Craters-Unnamed_Crater-PIA07202-PCF-LXTT.jpgUnnamed Crater with Pedestal (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)245 visiteThis Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an Unnamed Impact Crater, a little over 2 Km (> 1,2 mi) in diameter, located in Noachis Terra near 50,4 South and 14,3 West. The Crater's Bouldery Ejecta Blanket has protected underlying material from being eroded away by wind, leaving the Ejecta up on a low Pedestal. This picture covers an area about 3 Km (approx. 1,9 miles) across, and is illuminated by sunlight from the lower left.MareKromium

Craters-Unnamed_Crater-Southern_Regions.jpgUnnamed Crater covered by Fog (Original NASA/MGS/MSSS b/w Frame)103 visiteCaption NASA originale:"Craters near the edge of the retreating South Polar Seasonal Frost Cap often have fog in them, this time of year. This MGS-MOC wide angle red image was acquired on July 13, 2003. It shows an Unnamed Crater, roughly 36 Km across, that is enveloped in Fog.
This picture was taken as a context frame for a high resolution view that was intended to show Dunes on the Floor of the Crater. That high resolution view was frustrated by thick Fog that hid the Dunes from view. This wide angle context frame shows that winds from the lower right (South/East) were blowing over the Crater, causing the Fog to bunch up in a wavy, rippled pattern. Winds streaming off the South Polar Cap toward the North create a variety of patterns in the Fogs formed by Water Ice or Vapor as the Seasonal Cap retreats during Southern Spring.
This picture shows an area located at about 66,4 South Lat. and 208,6 West Long; sunlight illuminates the scene from the upper left (North/West)".
