Urvara Crater and Pongal Catena

Urvara Crater and Pongal Catena
Urvara Crater and Pongal Catena Dawn observed this scene on Sept. 28, 2015, from its third mapping orbit at an altitude of 915 miles (1,470 kilometers). On the lower left is the center and northwestern part of Urvara Crater, Ceres’ third largest. Extending outward from Urvara on its right is a narrow depression 60 miles (97 kilometers) long called Pongal Catena. (Pongal is a popular Hindu harvest festival of thanksgiving, celebrated by the Tamil people.) It may be the result of stresses produced by the tremendous impacts that formed Urvara and the even larger Yalode Crater (which we will see below). We saw other catenae above. This picture is centered on this map at 36°S, 263°E. Full image and caption. NASA / JPL-Caltech / UCLA / MPS / DLR / IDA
