Abstract

The fatal anomaly of the Advanced Earth Observing Satellite-2 (ADEOS-2) on the polar earth orbit of 803 km altitude, that was due to an electric power loss from 6 kW to 1 kW, occurred off the coast of Peru from 16:12 to 16:16 UT on 24 October, 2003. It was considered to be caused by the short/open of the electronic cables in the harness connected the solar paddle and the satellite body. That had been probably triggered by electrostatic charging and subsequent discharging of the electronically floating Multi-Layer Insulation (MLI) blanket of the harness by the energetic auroral electron flux when the ADEOS-2 was passing through the northern aurora oval just before the anomaly. Measurements of the onboard energetic charged particle detector were not fully available around the anomaly due to the data transmission schedule. However the NOAA-17 satellite, that was almost 30 km just above the ADEOS-2, observed an extraordinary enhancement of the energetic electron flux at the nightside aurora oval. The total energetic electron flux (larger than 30 keV) is calculated to be 2.94 x 10(exp 10) (particles/sq cm). This total flux is supposed to be enough to charge the floating MLI blanket deeply and induce discharging for trigger arcs., 資料番号: AA0049206095, レポート番号: JAXA-SP-05-001E

Abstract

A magnetic sail is a unique propulsion system, which travels interplanetary space by capturing the energy of the solar wind. In order to simulate the interaction between the artificial magnetic field produced around a spacecraft and the solar wind, scaled-down laboratory experiment was conducted in a space chamber. Preliminary results showed some strong interactions between the high-density and high-velocity plasma flow and an artificial magnetic field, hence the possibility of the magnetic sail simulator is provided; however, further improvement is required to realize a collision-less solar wind plasma flow in the laboratory., 資料番号: AA0049120020
