| Popis: | As a countermeasure for suppressing space debris growth, the Institute of Space Technology and Aeronautics, Japan Aerospace Exploration Agency (JAXA), is investigating an active space debris removal system that employs highly-efficient Electrodynamic Tether (EDT) technology as its orbital transfer system. Firstly, a small, expendable EDT package is under development that consists of a bare conductive tether and Field Emission Cathodes (FECs) that utilize carbon nanotubes. This package presents a possible technique for lowering the orbit of a debris removal system without the need for propellant. A test flight experiment using a rocket upper stage or a small satellite is planned for establishing and demonstrating the EDT technology. First, precise numerical simulations are performed for some aspects of mission analysis, such as available electric currents, orbital changes, tether stability, and deployment dynamics. The status of the trial fabrications and some evaluation test of the tether such as electric discharge are also described. 資料番号: AA0049206088 レポート番号: JAXA-SP-05-001E |
