概要

The increase in the orbital debris population is becoming a serious problem for human space activities. One of the most effective solutions to remediate the on-orbit environment is the active removal of existing large orbital debris. In order to realize low-cost active debris removal systems, simple and efficient deorbit propulsion is needed. Electrodynamic tether is a promising candidate for such a propulsion system because of its propellant-less mechanism, high-efficiency in weight and electrical power, and ease of attachment to debris. The first half of this paper describes the fundamentals of the electrodynamic tether including its advantages and disadvantages, and the strategic roadmap of the development of the active debris removal systems using the electrodynamic tether. The second half describes the current research and development status of the system and key technologies for a demonstration flight of the electrodynamic tether as the first step of the strategic roadmap.
