A group of experts from various fields for research on space exploration

Key words: space engineering, space art, space medicine, life environment, physical education

01nishioka01       Members of this unit conduct multidisciplinary, or cross-sectional, research on “space exploration”, with an awareness of trends in space utilization in modern times. The research unit aims to develop space technologies (including propulsion, aerodynamics, thermodynamics, environment, and robot technologies) and contribute to the next generation of space exploration.




Space exploration as a general science and technological capabilities

       Space exploration requires collaboration among researchers from a variety of fields, which makes thi field attractive. For researchers of the University of Tsukuba, a university located in the vicinity of the Japan Aerospace Exploration Agency (JAXA) as its strong point, it is an attractive collaborative research institution. However, as the proverb “The grass is always greener on the other side of fence” goes, the University of Tsukuba conducts research in a significantly larger number of academic fields than the JAXA, an institution with an advanced research environment specializing in space exploration, and has valuable resources that are unavailable in the aerospace exploration agency. Once you are in space, its infinite possibilities across a wide variety of academic disciplines, which you have not been able to even image, come to your mind: What effect will outer space have on organisms (which relates to medicine)? What forms of new expression can be created in a zero-gravity environment (which relates to art)? For specialized research institutions, universities are attractive because abundant academic resources are available to them. When our unit received a proposal of collaborative research made by the JAXA, and recruited participants from researchers of the university, Associate Professor Nasahara of the Faculty of Life and Environmental Sciences; Professor Sakurai, the Director of the Proton Therapy Center; and Professor Osaka of the Faculty of Art and Design responded, and the “Tsukuba Space Frontier Forum” on a wide range of subjects, including topics related to radio astronomy, research on remote sensing of agricultural fields from outer space, and space art in a zero-gravity environment, was held.


A group of specialists with a moderate level of association among them

       I am specialized in research on mild combustion phenomena, for which simulation methods are effectively used, and the specialty of Professor Kasahara, who transferred to Nagoya University, is new rocket engines that utilize the energy of detonations at a rate of Mach 10. Associate Professor Kameda, a member from the Faculty of Engineering, Systems, and Information, promoted collaborative research and development with the JAXA as the leader of a student project for the development of “Yui”, an ultra-small satellite. Associate Professor Fujino of a faculty related to electricity, a specialist in electromagnetic hydrodynamics, conducts research on the magneto-hydrodynamic (MHD) method to reduce shock waves generated at the time of re-entry (Figure 2). Researchers Yokota and Shimamura, young new members, are specialized in the development of electric (including the ion engine used for Hayabusa, an asteroid explore) and laser propulsion machines, respectively, which are space propulsion machines developed based on innovative ideas. We hope that the unit will provide “opportunities” for specialists from different fields to develop relationships with each other that center on space while conducting research on their specialties.
