A Note on System of Electrodynamic Tethering

Priyadarshini Jha

Electrodynamic Tethers (EDTs) are long conducting wires, such as those deployed from tether satellites, that can work on electromagnetic principles as generators (converting kinetic energy to electrical energy) or motors (converting electrical energy to kinetic energy). The travel of a conductive cable through a planet’s magnetic field generates electric potential across it. Crafts can employ long, powerful conductors (albeit not all tethers are conductive) as part of a tether propulsion system to modify the orbits of spacecraft. It has the potential to dramatically reduce the cost of space travel. When direct current is applied to the tether, it exerts a Lorentz force against the magnetic field, while also exerting a force on the vehicle. It can either accelerate or decelerate a circling spaceship. Several uses for electrodynamic tethers have been identified throughout the years for prospective usage in industry, government, and scientific research. A number of factors influence the metal conductor chosen for use in an electrodynamic tether.
