Glushko is a young impact crater attached to the western rim of the crater Olbers. Glushko possesses a high albedo and is the focus of a prominent ray system that extends in all directions across the nearby surface. It has sharp, well-defined features that, combined with its higher albedo, are indicative of a young impact crater. There is a small outer rampart, and material along the inner walls has slumped to form shelves and ramparts. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
