Outline of Final Research Achievements

We study the aqueous environment system on asteroids and Mars through exploration data and returned samples. We reconstruct the formation history of C-type asteroid Ryugu, water and material distribution, and water-rock reactions in the parent body of Ryugu based on remote sensing observations and analysis of returned samples by Hayabusa 2. We also reconstructed the stratigraphy formed by a result of water-rock reactions on Mars and established a methodology to create a map of subsurface hydrosphere of Mars.

Academic Significance and Societal Importance of the Research Achievements

本研究計画の学術的意義は、宇宙における水の存在とその起源、進化、および生命の可能性に関する理解を深めたことである。小惑星リュウグウからのサンプル採取と地球への帰還により、採取された物質の詳細な解析と研究が可能となった。社会的には、地球外の生命の存在や進化の理解を促し、人類の存在意義や宇宙における位置づけに関わる根本的な問いに対する解答を提供する可能性が見いだせた。本研究課題により得られた水惑星の成り立ちに関する知見は、学術的な理解と社会的な進歩の両面で重要な意義を持つと言える。
