Recent observations of the Moon by spacecraft

Abstract

Lunar flyby, orbiting, and landing spacecraft in the last ten years have provided an excellent definition of the nature of the lunar surface, and important information about the lunar interior. Some of the major controversies concerning the Moon appear now to be resolved.
