Most Densely Cratered Regions on the Moon (IMAGE) NASA/Goddard Space Flight Center Caption A lunar topographic map showing one of the most densely cratered regions on the Moon. The topography is derived from over 2.4 billion shots made by the Lunar Orbiter Laser Altimeter instrument on board the NASA Lunar Reconnaissance Orbiter. These most heavily cratered areas are among the best candidates to study and explore to understand the earliest lunar history.
