 note = {About fifty years have passed since the first launch of the artificial satellite in the earth orbit. During the time, several thousand rockets and satellites have been launched and the total mass will be estimated several thousand tons. These expensive rockets and satellites turn out debris when they finish their missions. Many of the debris still move around the earth, which brings increased anxiety of collision with the satellites in service or the International Space Station (ISS) under construction. Therefore, in the Institute of Space Technology and Aeronautics (ISTA), JAXA, the debris problem has been investigated comprehensively from the viewpoint of observation, protection and prevention of occurrence. This paper describes the results of the observation and protection research area., 資料番号: AA0048129019, レポート番号: JAXA-RM-04-011},
