“…The effectiveness of the different disposal methods depends strongly on the type, mass and orbital position of the satellite. Such concepts for the removal objects from orbits include tethering, tugging, beaming with an electrostatic tractor (for GEO) [49], ion-beaming through relocation and lasering, net capturing [50], docking with a nozzle (especially in GEO), harpooning, de-orbiting with a drag augmentation sail, and de-orbit kits [51]. There are, however, also passive debris removal concepts.…”

The growth of orbital space debris is both a consequence of and a potential hindrance to space activities. The risks posed by space debris propagation in the most used orbital regions highlight the need to adequately address the challenges posed to the sustainability in outer space. The preservation of the access to and usability of outer space in the long-term requires that action is taken which has to be the result of both mitigation and remediation measures for existing and future space missions. As the enforcement of such technical measures will depend on adequate regulation, they need to be approached also from a legal perspective. The deficiencies in law for space debris remediation mechanisms originate from the fact that although technical concepts have been developed, the legal framework for space activities does not impose any legal obligations for debris removal and on-orbit servicing. Nevertheless, an overview of the relevant legal framework shows that there is a legal basis for the protection of the outer space environment which can, as has already been the case with space debris mitigation guidelines, be substantiated in more concrete terms by the formulation of voluntary, non-binding instruments and included in national legislation.

“…The ever-increasing population of space debris poses a significant threat to the on-orbit serving spacecraft; thus, it has been a growing concern for the academic and industrial communities [1]. Many novel space debris capturing and removal methods have been proposed and developed [2]. Among these, the electrodynamic tether (EDT) system is an appealing technology as an active space debris removal system owing to its advantages of low mass, compact size, lack of propellant, and ease of operation [3,4].…”

This study develops a coupled multiphysics finite element method for the dynamic analysis of a bare flexible electrodynamic tether. Contrary to the existing methods, the new method discretizes and solves the orbital motion limited equation and the dynamic equation of an elastic flexible tether simultaneously. First, the new method is verified via comparison with the existing methods in a straight tether situation. Second, the number of tether elements, tether bending deformation, and two design parameters at the cathodic end affecting the electrical current are investigated. It is determined that the tether bending deformation and the two parameters i.e., the impedance Z T and Φ PW have a significant impact on the electron collection efficiency of an electrodynamic tether system. The results indicate that the proposed method should be applied in the refined mission analysis.
