Hummocky Terrain

December 4, 2012
NAC image M115475912R shows hummocky terrain north of the central peak of Tsiolkovskiy, still within the crater rim but outside the region flooded by mare basalt. The hummocks formed as the crater rebounded after the shock of impact dissipated. Image is 940 m wide, with an incidence angle of 75°. Credit: NASA/GSFC/Arizona State University
