| Research Abstract |
A new space propulsion system using stardust as propellant was proposed. It is expected that such system can reduce the propellant that we must bring from the earth. The new accelerator in which the solid micro particles that imitate stardust was charged through plasma and the new propellant supply module in which the supply was not depended by gravity were designed and produced, and the acceleration performance of micro particles was examined. As a result, a high charge efficiency that is almost the theoretical limit value is achieved, and one order higher value of thrust was obtained compared with the preceding study.
