of the debris relative to the spacecraft. The dynamic model of the spacecraft caters for several perturbing effects , such as Earth and Moon gravitational field asymmetry and the Earth's oblateness effect ...
Tides have largest impact on gravity measurements compared to all other environmental effects . They are a direct result of the gravitational forces of the planetary bodies, mainly the Moon ...
of the telescope, the selenocentric coordinates of each of the reflectors, as well as orbital elements of the Moon . In addition, the interest has been directed more specially towards the study of the rotational ...

gravitational effects from the moon and Jovian planets (Jupiter, Saturn, Uranus, and Neptune) influence solar activity and climatic conditions on Earth. Then, standard statistical methods are used to determine ...
Abstract:The passive retroreflector arrays placed on the moon by Apollo 11, 14 and 15 astronauts continue to produce valuable Earth- Moon range measurements that enable high-precision tests ...
the local normal is tangential to the gravitation field line at the observation point. Therefore, the measured zenith distances involve all the instantaneous gravitational field distortions. The direct ...
the primary body under the gravitational attraction, and a small lag angle between the direction of the bulge and a line that connects the two bodies have been reproduced. We measure the angular velocity ...
deviation from an ideal ballistic path is measured en route, then small corrections are made. The vehicle V2's, which exploded, in mid-air, despite their is virtually steered to the Moon , which subtends ...
