AB: We are entering a new era of utilization of space as Human territory (Humanosphere) for sustainable human society. From this point of view, a comprehensive academic study of the space environment could provide fundamental knowledge for developing space infrastructure such as huge power station ( Solar Power Satellite :SPS). Such study should cover not only the solar terrestrial relations but also possible nonlinear effects of space plasma onto large space structures. Since we have reached a state of understanding the framework of solar-terrestrial relations, we need to proceed our research for more practical objectives, which are directly related to the human activity in space. In the preset paper, we review the state of art of our knowledge of the space as Humanosphere from a view point of space plasma physics. I will then discuss the trend and perspectives of the role of space plasma physics, especially space plasma simulations in the coming new era of space civilization (utilization and beyond). The International Space Station is one of the human space activities at the ionospheric altitude level in the very near future. However, beyond the ISS era, much higher space activities will follow towards higher space civilization based on a very large structure such as Solar Power Station (SPS). I will discuss first the need of large scale space development such as the SPS to avoid a possible catastrophe of human life on Earth by the end of this century. Then I will touch upon possible plasma physics problems emerging from such large scale space development. The huge structure and the high voltage power supply for the microwave power transmission from the SPS definitely electromagnetically interact with space plasmas. Also much higher level artificial ion injection from the electric propulsion engine to carry such large structure into the GEO will create a large modification of the natural magnetosphere. These issues will demand the contribution by space physicists and simulationists.
