Secondary Crater-Chains or Signs of multiple and simultaneous Cometary Impacts? (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

Caption NASA:"This view captured by MESSENGER's wide angle camera (WAC) shows many Secondary Crater-Chains that originated from a Primary Impact Crater located outside this image, to the West. The Secondary Crater-Chains are formed as the Parent Crater-forming event launches Ejecta into the surrounding area. The chunks of Ejecta dig out their own craters which sometimes overlap to form a long valley-like depression. These features are striking though not uncommon on Mercury's battered Surface. Some other examples of Secondary Craters can be found at Abedin Crater".
