Unnamed Craters in Syrtis Major Planum (Original NASA/MGS/MSSS b/w Frame)

Caption 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".
