Exploration Mission to Halley's Comet
Kozaburo Inoue
Collaborative Researcher,
Institute of Space and Astronautical Science,
Japan Aerospace Exploration Agency
"I will introduce Mr. Kozaburo Inoue. Mr. Inoue entered Institute of Industrial Science, University of Tokyo in 1963. Although the name of the institute was changed afterwards to Institute of Space and Aeronautical Science, University of Tokyo, and then to Institute of Space and Astronautical Science (ISAS), he has been engaged in a study of development of satellite communication equipment and communication system of scientific satellite since the initial stage of Japanese scientific satellite development. He was engaged in more than 20 satellite missions of scientific satellite. In particular, Halley's comet which can be observed from the earth every period of 76 years is a subject of concern of the whole world. As an engineering chief of "Exploration mission for Halley's comet" whose satellite was launched to the orbit around the sun, he poured all his energy into developing an explorer that has never been experienced deep space communication of 2 AU (300 million km) in the satellite side under the limitation of 140 kg of weight and less than 100 W of power consumption and constructing a 64 m diameter antenna at Usuda, operational station of deep space communications and communication system. The full text below has splendid contents as a record about Mr. Inoue's hard work at that time. He was retired from his job in 2003, but he is still active as an adviser and a reviewer as a collaborative researcher of ISAS. He enjoys playing tennis and go other than watching sports games and listening to music in his spare time." (By Tomoki Obuchi, SJR Editorial Member)
