Science Applications, Part 1

The tethered satellite system mission can allow direct observation of the structure and the dynamics of the lower atmosphere; as well as answer some basic questions on the chemical composition of the atmosphere; the coupling mechanisms between small and large scale motions; the global wind field of the lower atmosphere, and how it is influenced by waves and tides; the mass, momentum, and energy fluxes in the lower thermosphere; how the above are affected by externally perturbed conditions (for example by magnetic storms, solar wind and its variability, etc.); and the pattern of electric current circulation and its relationship with the magnetospheric environment. Fundamental plasma processes can also be studied. Similarity of conditions in other plasmas in space makes it possible to get information on the magnetospheres of the giant planets or more generally on the solar system. The electrodynamic phenomena associated with the Jovian satellite Io (radioemission, UV emission, energetic electron precipitation) can be examined by simple scaling to the terrestrial case.
