Outline of Final Research Achievements

In this study, we constructed a light scattering model of ejecta curtain emerging at impact to obtain precious information on target bodies from observation of the ejecta curatin. Conducting numerical simulations and laboratory experiments of impact cratering and light scattering, we revealed the dependence of light scattering on the form and structure of ejecta curtain, the particle size distribution, the particle number density distribution, the scattering phase function of ejecta particles, the solar phase angle, and so on. The products of this study is expected to be applied for the future planetary missions with impact experiments in space.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は，はやぶさ２の衝突実験をはじめ今後の宇宙衝突実験を伴う惑星探査計画において，イジェクタカーテンのその場観測の重要性を改めて意義付けるものであり，衝突対象天体の情報をより適切に引き出すことを可能とするものである．
