Space Japan Club (in English) 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."

Special Report (in English) Discussions on Optical Communications started in CCSDS Tatsuya Mukai, Yoshihisa Takayama, Nobuhiro Kura, and Nicolas Perlot "In CCSDS, space networking by radio communications has been discussed and recently a study group for optical communications was formed in CCSDS because this technology has several advantages and has matured in the last decades through important developments and demonstrations." From Aerospace America (in Japanese) UAV Roundup 2011 This article was translated with the permission of AIAA by Yoshiaki Suzuki, Yoshihisa Takayama and Hiromitsu Wakana Satellite Communications and I (in English) Looking back 10 years of experience in satellite developments Naoko Yoshimura, NICT, Japan "I am writing here for the second time. It’s been ten years since I submitted the last essay in 2001. I would like to look back over the past decade. Ten years ago, “KIZUNA” (WINDS) the high‐speed internet satellite was at a very early stage of conceptual design. Now it in orbit, and being operated very well for various satellite experiments; it’s a really impressive achievement. " Space Japan Interview (in Japanese) Learned from Development of CS "Sakura, Cherry in English", blooming in the universe of "Showa".

Reviewer: Takashi Iida, Editorial Advisor "This book gives us a fresh impression, since it has a big title and describes many predictions that we have not even thought so far. Among them, it is the most impressive that the U.S. prosperity has just begun, and the 21st century is the opening of the U.S. era.
