Beyond 2000, more complicated systems will be developed in space, based on ten years of experience of the space station. An example is the 10 MW (mega watts) SPS (Satellite Power System) which was once studied by a Japanese group as a test bed for the technologies developed during the earlier phase of the space station program and the environmental research. The 10 MW SPS consists of main subsystems of an SPS; solar cell panel, electrical power line, microwave generator and a power transmitting antenna. The area of the solar panel is 400 m x 600 m, which is large enough to generate an electrical power of 30 MW with photovoltaic devices. All phases of this project from construction through operation have been considered to be the objectives of this mission. The concept has been reexamined from standpoint of a space station mission. As a result, several findings have been pointed out to refine the concept. To reduce the cost, the method of the construction should be modified in the direction to take advantage of low cost service of the space infrastructure the space station provides rather than to build an independent space system. It is important to incorporate various missions and technologies inviting more participants of the joint enterprise to share the mission. Possibly there will be users to pay for the mission product. The more benefit of ouptut of the system has to be demonstrated prior to initiation of the project to get financial support.
