B. Fong Chao's article entitled “As the World Turns, II” (Eos, Dec. 3, 1991), was written in an informal manner appropriate for a broad spectrum of readers, many of whom might otherwise have had little interest in the subject of Earth rotation. U

An analysis of six years of lunar-laser-ranging data gives a zero amplitude for the Nordtvedt term in the earth-moon distance yielding the Nordtvedt parameter eta = 0.00 plus or minus 0.03. Thus, earth's gravitational self-energy contributes equally,

Lunar physical librations and laser ranging

Autor: D. H. Eckhardt, M. A. Slade, James G. Williams, William M. Kaula

Publikováno v: The Moon. 8:469-483

The analysis of lunar laser ranging data requires very accurate calculations of the lunar physical librations. Libration terms are given which arise from the additive and planetary terms in the lunar theory. The large size of the recently discovered

The Lunar Laser Ranging Experiment: Accurate ranges have given a large improvement in the lunar orbit and new selenophysical information

The lunar ranging measurements now being made at the McDonald Observatory have an accuracy of 1 nsec in round-trip travel time. This corresponds to 15 cm in the one-way distance. The use of lasers with pulse-lengths of less than 1 nsec is expected to

Afcrla Lunar Laser Range And Photography Instrumentation

Autor: M. S. Hunt, R. L. Iliff, D. H. Eckhardt

Publikováno v: SPIE Proceedings.

A lunar laser system is being developed for Air Force Cambridge Research Laboratories. It has been designed to detect, photoelectrically and photographically, ruby laser pulses which are retro-reflected from optical cube corners loca-ted on the moon.
