Although original concept of the magnetic sail depends solely on very large magnetic field generated by using such device as superconductors coil, in 2001, Winglee et al. proposed an efficient method to realize a huge magnetic field around a spacecraft with an assistance of plasma emission. From their theoretical analysis of what they call as mini-magnetospheric plasma propulsion (M2P2), it was shown that if a dense plasma were exhausted near the center of the dipole magnetic field, the magnetic field can be expanded far away from the spacecraft, thus the energy of the solar wind can be captured by this huge magnetic field in spite of very low-density solar wind. Based on the idea of such plasma sail, firstly studied were deep space missions targeting at some outer satellites like Jupiter. Plasma sail has great advantage against other electric propulsion systems because of its ability to produce larger thrust to power ratio. However, the thrust formula shown by Winglee et al. is doubtful in some respects. Therefore, an analysis model is discussed that can describe a process of the magnetic field inflation accompanied by plasma emission from the spacecraft., 資料番号: AA0046978013, レポート番号: JAXA-SP-03-001}, pages = {68--71}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {磁気プラズマセイル(MPS)の研究}, volume = {JAXA-SP-03-001}, year = {2004} }
