“…This activity is currently financed with 3M€ by the European Commission under the FET-OPEN project Electrodynamic Tether technology for Passive Consumable-less deorbit Kit (E.T.PACK). E.T.PACK involves the University Carlos III of Madrid as coordinator of the project and responsible for the mission analysis, SENER in charge of the system engineering and the avionics, the University of Padova as responsible for the tether deployment mechanism validation, the TU Dresden in charge of the electron emitter and ATD and IKTS working on new material developments [1,2]. The objective of the E.T.PACK project is to develop the deorbit kit (DK) up to TRL4 by 2022.…”

“…A recent project funded by the European Commission -BETs - [12] analyzed in details the use of electrodynamic tape tethers instead of round tethers due to their higher survivability to space debris impacts and a better electrodynamic performance due to the larger perimeter of the tether cross section for equal tether mass. A multi-national study currently been conducted on the use of tape tethers for deorbiting is the H2020 European project "E.T.PACK" [13]. The materials investigated in our research program, their dimensional characteristics and the related missions are summarized in Table I.…”

In the last several years, the need for an alternative to chemical propulsive systems for low-orbit satellite deorbiting has become increasingly evident; a Tethered System can provide adequate thrust or drag without the complications of combustions and with a minimal impact on the environment. In this context, the authors are part of a team that is studying various tether applications and building a prototype of an electrodynamic tether system. The goal of this paper is to characterize tether materials in order to find valid solutions for future space tether missions. Mission requirements (e.g., the survivability to hypervelocity impacts and the capability to damp oscillations in electrodynamic tethers) influence the choice of tether parameters such as cross section geometry (round wires or tapes), materials, length, and cross section sizes. The determination of the elastic characteristics and damping coefficients is carried out through a campaign of experiments conducted with both direct stress/strain measurements and the laboratory facility SPAcecRraft Testbed for Autonomous proximity operatioNs experimentS (SPARTANS) on a low friction table at the University of Padova. In the latter case, the stiffness and damping of a flexible line were verified by applying different tensile load profiles and then measuring the tether-line dynamic response in terms of tension spike amplitude, oscillation decay, and estimation of the damping coefficient.
