The rapid growth of space utilization, increase in demand for small satellites and their launch opportunities, and the rise of mega-constellations means an increased threat from space debris. Considering the current situation, Post-Mission Disposal (PMD) is considered to be important technique for the prevention of space debris and sustainable space development. ALE and Japan Aerospace Exploration Agency (JAXA), as a part of the JAXA Space Innovation through Partnership and Co-creation (J-SPARC) project, are developing a PMD device using an Electrodynamic tether (EDT) to demonstrate the de-orbit of satellites. In this project, we are planning to launch a satellite equipped with a PMD device in 2021. The EDT is effective for satellites in a wide range of orbits within the Earth's magnetic field. It uses Lorentz force, an interaction between the Earth's magnetic field and electrical current flowing through the tether and atmospheric drag, to decrease the time needed to de-orbit. Our developed PMD device is able to significantly reduce the time required for the satellite to reenter the atmosphere. It can be utilized as a countermeasure for the prevention of space debris. This paper provides details of the developed PMD device, the numerical analysis of de-orbit, and the mission overview.
