A pulsed-operation MPD Thruster was not fit for utilization in space. In this study, the MPD thruster doesn't have the coil for external magnetic field application but permanent magnet, Samarium cobalt. So, if magnetic Curie temperature is taken into consideration, the radiation-cooled thruster without cooling water can be designed. The manned Mars explorations which are a final objective of this study are missions for which a high specific impulse is needed. Using hydrogen, we could obtain a result of thrust 41.9 mN, specific impulse 2870 s, and thrust efficiency 12.5 %. We will perform performance improvement and heat analysis for development of a radiation-cooled thruster. And, to decrease cathode damage, we designed multi-hollow cathode. Using it, a new water-cooled thruster with changing anode geometry, distance between electrodes and magnet field strength was made.
