Abstract:
The study focuses on addressing the escalating challenge of orbital debris in Low Earth Orbit (LEO), non-functional satellites, space vehicle stages, and fragments resulting from collisions and explosions. Although there are over 25,000 pieces of debris exceeding 10 cm in diameter in LEO as of 2022, 50 derelict objects are identified as particularly concerning. Using the Linux-based simulation software, TeMPEST (TEthered Mission Planning and Evaluation Software Tool), the research simulates Electrodynamic Tether Systems (EDTs), featuring a long conducting tether and, in some cases, an energy storage module, for the deorbiting of these objects. By systematically varying EDT properties and orbital elements, the simulation aims to ascertain the optimal operational range for the tethered system. This insight, coupled with the understanding derived from Space Laws, will guide the identification of viable debris mitigation strategies, facilitating the targeted removal of the 50 most problematic debris objects from LEO.
