The E.T.PACK project aims to tackle space debris with dispensable aluminum tape that will help pull the satellite out of orbit when its mission is complete.
Developed by a team headed up by the Universidad Carlos III de Madrid, the E.T.PACK (Electrodynamic Tether technology for Passive Consumable-less deorbit Kit) project relies on a low work-function tether that would be loaded into the spacecraft prior to launch. At the mission’s end, the craft would unfurl the tether, which is thinner than a human hair and coated in a material that emits electrons when heated by sunlight. The now-released tether would then generate electricity via the Lorentz force phenomenon, powering thrusters to force the spacecraft out of orbit with no extra fuel required.
