This NAC image shows a close-up view of the craters Vyasa and Stravinsky (PIA11360). Stravinsky is the smooth-floored crater partially seen on the right side of the image that overlies the rim of the larger, rougher crater Vyasa in the center and left. The low-Sun lighting angle casts distinctive shadows that show Mercury's rough surface, pockmarked by craters of all sizes. Small craters are visible on the smooth-floor of Stravinsky because of the high resolution of this image.
