A power subsystem installed in the first Japanese Halley's comet explorer, "SUISEI" was developed by extraordinary efforts for the reduction of its weight and size, because the payload capability of a launch vehicle was restricted. Consequently, for instance, output power to weight ratio of the solar cell panel for "SUISEI" was improved by about 30% as compared with that of a conventional body-mount type solar cell panel for scientific satellite use. Besides, flight performances of the subsystem almost satisfied required ones for about 200 days from the launch of "SUISEI" to the nearest approach to the comet. We could establish design techniques of a power subsystem for interplanetary spacecraft use by means of this success.
