Saku Tsuneta Director General

Message from the Director General April 2015 Saku Tsuneta Director General Institute of Space and Astronautical Science Japan Aerospace Exploration Agency While the Institute of Space and Astronautical operation of the magnetosphere observation satellite Science (ISAS) is a part of the Japan Aerospace “Akebono” launched in 1989, was terminated due to Exploration Agency, at the same time, it has been deterioration of the instruments and a lowered flight operated as the Inter-University Research System altitude. “Akebono”, carried out observation activities (Institute) (*1). This makes ISAS a unique research of aurora and the Van Allen radiation belt for 26 institute. ISAS, being a research hub for research- years, and resulted in 311 refereed paper and 254 ers around the nation, has realized missions that theses (36 of them are doctoral thesis). cannot be accomplished by an individual university or institute. Under close collaboration with research- ISAS currently operates 7 satellites and probes, ers in space science and space engineering, ISAS including “Hayabusa 2”, (*2) PROCYON, “Hisaki”, has proposed and executed a series of ambitious “Akatsuki”, “Hinode”, “Suzaku”, and “GEOTAIL”.
