Craters-Schiaparelli_Crater-Layers-02.gifLayers in Schiaparelli Crater (Natural Colors; credits: Lunexit)55 visiteDa "NASA - Picture of the Day", del giorno 29 Novembre 2009:"Is this a picture of Mars or Earth?
Oddly enough, it is a picture of Mars. What may appear to some as a terrestrial coastline is in fact a formation of ancient layered hills and wind-blown sand on Mars.
The above-pictured region spans about 3 Km in Schiaparelli Crater. What created the layers of sediment is still a topic of research. Viable hypotheses include ancient epochs of deposit either from running water or wind-blown sand. Winds and sandstorms have smoothed and eroded the structures more recently.
The "water" that appears near the bottom is actually dark colored sand. The image was taken with the Mars Global Surveyor Spacecraft that operated around Mars from 1996-2006 and returned over 200.000 images".MareKromium

Craters-Terby_Crater-01.jpgThe Sedimentary Layers of Terby Crater (1 - Original NASA/MGS/MSSS b/w Frame)53 visiteOriginal caption:"This MGS-MOC image shows some of the light-toned, layered, Sedimentary Rock Outcrops in Northern Terby Crater. Terby is located along the North edge of Hellas Planitia. The Sedimentary Rocks might have been deposited in a greater, Hellas-filling sea — or not. Today, the rocks are partly covered by dark-toned Sediment and Debris".
Location near: 27,2° South Lat. and 285,3° West Long.

Craters-Tikhonravov_Crater-PIA07196.jpgThe "Eyes" and "Eyebrows" of Tikhonravov Crater (Original NASA/MGS/MSSS b/w Frame)75 visiteCaption NASA originale:"This red wide angle MGS-MOC image shows Tikhonravov Crater in Central Arabia Terra. The Crater is about 386 Km (approx. 240 miles) in diameter and presents two Unnamed Impact Craters at its center that have dark patches of Sand in them, giving the impression of pupils in two eyes. Each of these two Unnamed Craters lies a dark-toned patch of Surface Material, providing the impression of eyebrows.
M. K. Tikhonravov was a leading Russian rocket engineer in the 20th Century. The crater named for him, despite its large size, is still partly buried, on its West Side, beneath the heavily Cratered Terrain of Arabia Terra. The center of Tikhonravov is near 13,5° North Lat. and 324,2° West Long. Sunlight illuminates the scene from the upper left".

The three circular crack patterns indicate the location of three buried Unnamed Impact Craters. These landforms are located near 41,9° North Lat. and 275,9° West Long. The image covers an area approximately 3 km (about 1,9 mi) across. Sunlight illuminates this scene from the lower left".
