Developing electrodynamic tether technology for the sustainable use of space.  The E.T.PACK team was established in 2019, when the European Innovation Council (EIC) granted the FET-OPEN project "Electrodynamic Tether technology for PAssive Consumable-less deorbit Kit". Its goal, i.e. the development of a deorbit device based on ElectroDynamic Tether (EDT) technology with TRL 4, was…
