Electromagnetic effects induced by the Space Station

Abstract

We have identified several mechanisms which can cause electric (E) and magnetic (B) field contaminations of the Space Station environment. The level of E and B fields generated by some of them such as the motion of the vehicle across the ambient magnetic field Bo and the 20-kHz leakage currents and charges can be controlled by proper design considerations. On the other hand, thcre are some mechanisms which are inherent to the interactior, of large vehicles with the plasma and probably their contributions to E and B fields cannot be controlled; these include plasma waves in the wake and ram directions and the effects of the volume current generated by the ionization of tie neutrals. The interaction of high-voltage, solar cell arrays with plasma is yet another rich source of E and B fields and it is probably uncontrollable. Wherever possible, quantitative estimates of E and B are given.

Optimizing Electrodynamic Tether System Performance

“…There have already been several investigations to assess the use of tethers on the ISS to account for this decay 41, , 43 46 as well as other electromagnetic effects. 47,48 This particular study employs unique attributes never before investigated to implement an EDT system for use on AIAA-2009-6734 14-17 September 2009, Pasadena, California the ISS. Variables such as the tether width, tether porosity, anode type and cathode type will be introduced as new system parameters to be explored.…”
