Outline of Research at the Start

火星衛星の起源の解決を目指すため、まず、対立する2つの有力な仮説「衝突説」と「捕獲説」の両説において、その形成過程を理論研究によって明らかにし、その形成過程と火星圏環境を再現した実験を行い、火星衛星の模擬物質を作成する。そして、火星衛星探査機 (MMX)に搭載される近赤外分光計(MIRS)と同一の装置を用いて、火星衛星模擬物質の近赤外スペクトルを測定する。火星衛星フォボスのMIRSによる観測は、2025年夏頃に開始される。観測されたフォボスのスペクトルを実験室で作成した模擬物質の近赤外スペクトルと比較することによって、火星衛星の起源に強い制約を与える。

Outline of Annual Research Achievements

火星衛星の起源の解決を目指すため、まず、対立する2つの有力な仮説「衝突説」と「捕獲説」の両説において、その形成過程を理論研究によって明らかにし、その形成過程と火星圏環境を再現した実験を行い、火星衛星の模擬物質を作成する。そして、火星衛星探査機 (MMX)に搭載される近赤外分光計(MIRS)と同一の装置を用いて、火星衛星模擬物質の近赤外スペクトルを測定する。本研究では、4つの研究計画から構成されており、2024年度は、以下の研究計画を実行した。<計画1> 火星衛星の形成過程に関する理論研究:「捕獲説」における、捕獲プロセスとその後の軌道進化の詳細を調べた。 「衝突説」において、衝突天体の組成を変えた計算を行い、形成される円盤の物理的特徴を明らかにした。<計画2> 火星模擬物質の作成と宇宙風化の実験:太陽風照射を模擬するHeイオン照射実験を行った。<計画3> MIRSによる火星模擬物質の近赤外スペクトル測定:隕石試料および再現実験で作成した模擬物質の近赤外スペクトルを、MMX搭載のMIRS にて測定した。 また、合成スペクトルのモデルの構築も行った。

Current Status of Research Progress
