Outline of Final Research Achievements

Space debris, in particular, cm-sized debris are important issue of space development. We performed a conceptual study for the deorbit mission by laser ablation with a high-intensity space-laser system. Among the steps of the deorbit operation of space debris, we performed the experiment of step 1; detection and step 2; tracking in the laboratory with 1/10 scale model of EUSO telescope. In addition, the optimization study revealed that the deorbit mission can work optimal condition in the sun-synchronous orbit, which can always stay in the twilight with the altitude of 600-900 km. Furthermore, we examined the ablation response for various debris materials and the way of the suppression of the rotation of them.

Academic Significance and Societal Importance of the Research Achievements

これまで全く有効な対策が存在しなかったcmサイズのデブリに対して、始めて実現可能な対策を提案するもので、社会的な意義が非常に高く社会的な関心も高い。追尾手法について、デブリの軌道位置を予測し、もっとも最適な位置で標的を待ち受ける新しい制御手法を開発した。さらに、衛星のミッション終了後のデブリ化阻止技術へ本件のレーザーアブレーションを用いた回転・軌道抑制技術の転用が可能であることが分かり、実用化に向けて私企業と具体的な議論を始めている。
