In fact, the Moon is the only natural satellite for earth that has existed on its own and keeps on revolving around the earth. Artificial Satellites Artificial satellites are the objects that are intentionally placed by humans which orbits the earth for practical uses. These artificial satellites ...
SOME DYNAMICAL PROPERTIES OF THE NATURAL AND ARTIFICIAL SATELLITESSome qualitative properties of the natural and artificial satellites in the solar system that can be understood in terms of the restricted three-body problem are discussed. Three problems are considered: The satellite system of Jupiter;...

The Moon's interior structure is investigated from seismograms of moonquakes and meteoritic and artificial impacts. The temperature of the central core may reach 1500 °C but a metallic iron composition is precluded by the Moon's moment of inertia. The Moon's center of mass is displaced toward...
The LASSII spacecraft is a sortie-mode satellite designed to be launched and recovered by Shuttle, and instrumented with a complement of plasma diagnostic tools which have been specifically designed to spatially an temporally resolve all the active elements within an ionospheric irregularity. The satel...
