| Abstract | Space tether system has wide variety of applications for technological and scientific missions such as momentum exchange orbit transfer by releasing payload connected with the tether, artificial gravity generation by rotating two bodies connected with the tether and scientific inspections of the upper atmosphere by multi probes on the long tether. The electrodynamic tether is a kind of space tether application that possesses the conducting tether and plasma contactors. It produces thrust on the earth orbit by the interaction between the current through the tether and the geomagnetic field. So, it can be used for orbit raising thrust force or orbit lowering drag force depending on the direction of the current. It also generates electrical power (electromotive force) by the conducting tether across the geomagnetic field. The electrodynamic tether also has the potential to provide a near-propellantless propulsion system, using the energy from sunlight converted to electrical energy. Therefore, the electrodynamic tether system can be applicable for various missions such as station-keeping, power generation, orbit raising, and the deorbit of largesized debris when some practical problems such as the tether cutting would be solved. |
