It is a super wide-field telescope (60 degree) that observes UV photons from air-showers produced by cosmic-rays in dark side of the Earth. EUSO is planned to be attached to Columbus module of International space station. It is promoted international collaboration of scientists among Europe, USA, and Japan. The phase - A study (conceptual design) under ESA has been successfully finished in July. However, Italian space agency and ESA are in difficulties to move to the phase-B study. Therefore, Japan and US team decided to challenge to the second phase of JEM/EF (Japan Experiment Module / Exposure Facility) mission., 共催: 日本学術会議, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113037}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {Extreme Universe Space Observatory(EUSO)}, volume = {22}, year = {2006} }
