The Jovian system with its rapid planetary rotation and strong magnetic field presents exciting opportunities for the use of electrodynamic (EM) tethers. Previous analysis for a radial, 10 km length tether demonstrated the possibility of propulsive forces as large as 50 Newtons near the planet. For orbital positions beyond about 2.5 Jovian radii, an EM tether can simultaneously be used for power and increases in the orbital altitude. Although the previous study demonstrated the physical feasibility of EM tether use at Jupiter, it did not address the issues of limited gravity gradient force for tether orientation and the practical use of this technology in an engineered system. This presentation will discuss these issues and current progress in an ongoing science/engineering transitional study.
