Craters-Unnamed_Craters-Syrtis_Major.jpgUnnamed Craters in Syrtis Major Planum (Original NASA/MGS/MSSS b/w Frame)53 visiteCaption NASA originale:"This MGS-MOC image shows a portion of Syrtis Major Planum, dominated in this area by two Impact Craters of differing age. The large one is about 1,3 Km (approx. 0,8 miles) in diameter, the smaller is about 250 mt (~820 feet) across.
The smaller Unnamed Crater has a well-defined Ejecta Blanket and Rays emanate outward from its center. The larger Unnamed Crater does not exhibit these features. The larger one is older, and its Ejecta Blanket and Rays have been removed and degraded over time".
Location near: 5,4° North; 294,2° West
Image width: ~3 Km (~1,9 mi)
Illumination from: upper left
Season: Northern Spring

Craters-Unnamed_Craters-Utopia_Planitia-00.jpgOld Buried Unnamed Craters in Northern Utopia Planitia (Original NASA/MGS/MSSS b/w Frame)53 visiteOriginal caption:"This MGS-MOC image shows 2 circular features on the Plains of Northern Utopia. A common sight on the Martian Northern Plains, these rings indicate the locations of Buried Impact Craters".
Location near: 65,1° North Lat. and 261,2° West Long.

Craters-Unnamed_Craters_with_Sedimentary_Rock_Outcrops-PIA07127-00.jpgSedimentary Rocks (Original NASA/MGS/MSSS b/w Frame)69 visiteCaption NASA originale:"Burial and Exhumation of Impact Craters, and their destruction by erosion, are common and repeated themes all over the Surface of Mars. Many Craters in Western Arabia Terra exhibit light-toned, Layered Outcrops of ancient Sedimentary Rock. Like the Sedimentary Rocks explored further to the South in Meridiani Planum by the Opportunity Mars Exploration Rover (MER-B), these "Intracrater Sedimentary Rocks" may have been deposited in water. This MGS-MOC image shows an example of light-toned Sedimentary Rocks outcropping in an Unnamed Crater that is much farther North than most of the similar examples in Western Arabia Terra. This one is located near 36,6° North Lat. and 1,4° West Long. and shows several old Impact Craters in various states of erosion and exhumation from beneath and within the Sedimentary Rock Materials. The image covers an area of approx. 3 Km".

Craters-Unnamed_Defrosting_Crater-PIA03921-00.jpgUnnamed Defrosting Crater (Original NASA/MGS/MSSS b/w Frame)66 visiteCaption NASA originale:"This MGS-MOC image shows a Surface in the South Polar Region, covered by CO2 Frost. In this springtime scene, the Frost has begun to sublime so that Sandy Surfaces exhibit an abundance of Dark Spots. The circular depression is probably the remains of an Impact Crater. In summer, the Spotted Surfaces in this image would be darker than their surroundings, because they are patches of Windblown Sand".
Location near: 67,6° South Lat. and 254,3° West Long.
Image width: ~3 Km (~1,9) mi
Illumination from: upper left
Season: Southern Spring

Craters-Unnamed_Fresh_Crater_in_Noctis_Labyrinthus-MGS.jpgFresh Crater (Original NASA/MGS/MSSS b/w Frame)56 visiteCaption NASA originale:"This MGS-MOC image shows a relatively Fresh Crater with dark, rayed Ejecta on an upland plain above one of the many depressions in the Eastern Labyrinthus Noctis Region. The presence of the dark rays emanating from the Crater suggests that the impact was a relatively recent event compared to other Craters of similar diameter in the scene. Over time, the dark Ejecta will fade and blend in with its surroundings, owing to settling of Dust from the Atmosphere".
Location near: 9,7° South Lat. and 94,8° West Long.
Image width: ~3 Km (~1,9 mi)
Illumination from: upper left
Season: Southern Summer
