Keywords惑星探査 / はやぶさ2 / 火星探査計画 / 水・物質循環
Outline of Annual Research Achievements

本計画研究は、「第1段階(H29・30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(H31・32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(H33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。はやぶさ2探査によるリモセン観測が予定通り実施されたことにより、2019年度からは、小惑星リュウグウのリモートセンシング観測およびそのデータ解析に従事した。また、2019年度には、リュウグウにおいて世界初となる、人口衝突クレーター形成実験も行った。クレーター形成で露出したリュウグウ内部物質のリモセン観測データの解析も併せて行った。

リュウグウの解析に加え、計画班では、将来の火星地下県探査のためのツール開発も行っている。我々は、レーダーサウンダー技術を応用し、地下水圏の露出部分であるクレーター壁や渓谷から内部へと続く、地下水圏の水平分布を取得する技術を開発した(Noguchi et al. 2019 GRL)。

Current Status of Research Progress
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

はやぶさ2探査で獲得したデータ解析の技術や知見を、他の太陽系天体観測へと展開すべく、火星および氷衛星の探査データ解析を専門とするPDを新規に雇用した。新規に雇用したPDは、2019年度に開発したレーダーサウンダー技術を用いた地下圏探査手法を地表面の情報と組み合わせて解析することで、確度の高い3次元地質図の作成を担う。
