The Japan Aerospace Exploration Agency (JAXA) has performed the research and development of debris removal systems equipped with electrodynamic tethers and this study is a part of this effort. Our goal is to develop a propellant-free debris de-orbiting system by the combination of the field emission cathode and a bare tether. In the preliminary experiments, electron extraction tests of carbon nanotube cathodes made by thermal chemical vapor deposition and arc discharge process were conducted. The results showed that the carbon nanotube cathodes had sufficient emission capability for the electrodynamic tether application, although its endurance performance was not sufficient in our test. Further investigations on the durability improvement and the optimization of electrode configuration hate been started.", "subitem_description_type": "Other"}]}, "item_5_description_32":
