Investigating the Moon’s Motion by Laser Rangingterminations have been especially interesting because radar measures distance (albeit in light-seconds rather than in meters) more directly than and independently of the classical astronomical triangulation methods. In addition to yielding precise distances, detailed examination of the reflected ene

Lunar Physical Libration Theorye Moon, is a very onerous task. The differential equations are complicated, mutually coupled and non-linear. The elaborate numerical treatment of . (1902) furnished solutions which remain authoritative to this day except for the modifications of . (1948) who replaced Hansen’s lunar theory with Brown’s theory.

Laser Measurement of Earth-Moon Distance and Selenographye then, there has been practically no interruption in observation of the Moon by radar, which has brought us a great deal of important information, including, in particular, a new lunar parallax value (cf. .., 1965).
