Questions of lunar bulk chemistry are being considered, giving attention to the depletion of the moon in iron and compounds more volatile than iron. Currently four seismic stations are operating on the moon to provide data for the study of the lunar interior. The travel times of seismic waves generated by artificial impacts have been used to determine the structure of the outer 150 km of the moon. New evidence fails to resolve the controversy whether the lunar interior is hot or cold. A schematic cross section of the moon is presented and problems concerning the origin of the moon are considered.
