Outline of Annual Research Achievements

本計画研究は、「第1段階（2017-2018年度）：はやぶさ2探査での観測データの取得準備、近傍観測」、「第2段階（2019-2020年度）：微惑星・水惑星・氷衛星の水・物質循環に関する地球科学データの抽出」、「第3段階（2021年度）：微惑星・水惑星・氷衛星の水・物質循環モデルの構築」からなる。本年度は、第二段階の最終年であり、水惑星天体から得られた観測データの解析をさらに進め、論文化に集中した。特に、はやぶさ２探査では、世界初となる人口クレーター形成により露出した小惑星リュウグウの内部物質データの取得にも成功した。これらの結果は、査読付き原著論文としてScience誌（Arakawa et al. 2020; Morota et al. 2020）やNature姉妹誌（Kitazato, Nakamura, Morota, Namiki, Okada, Watanabe et al. 2021）に掲載されることとなった。

本年度は、他の計画班との融合研究も進み、特にB01分析班と行った研究からは、火星雪物の発見（Koike, Usui et al. 2020 Nature Communications）や、A03理論班と行った准惑星セレスの分光観測データ解析法の開発（Kurokawa, Usui et al. 2020 JGR）が特筆される。また、将来の火星探査を見据えた予察的な研究も融合研究から生まれている（Usui et al. 2020 Space Science Review; Hyodo et al. 2020 Scientific Report）。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

はやぶさ2探査が計画通りに進んでいるため、その解析および成果発表とも予定通り進んでいる。

Strategy for Future Research Activity

プログラム最終年である２０２１年度に向け、融合研究を加速すべく、地質学をバックグラウンドとするPDを新規に雇用することになっている。
