Outline of Research at the Start

高ΔV可能なキックモータ(軌道変換用ロケット)を搭載し,静止トランスファー軌道(GTO)や月軌道ゲートウェイ(Lunar Orbital Platform-Gateway, LOP-G)から月,火星,金星などの深宇宙に向かう探査ミッションを高頻度に実施できる超小型探査機システムを開発する.重要な研究要素は,①超小型探査機システムの長期ミッション信頼性の向上,②高推力キックモータ作動時の課題に対応する探査機システムであり,これら二点の解決方策の宇宙実証を目指す.これらの成果を通じて,超小型探査機を用いて深宇宙探査を高頻度に実施する基盤技術を整え,太陽系科学の発展や深宇宙領域の民間活用に寄与する.

Outline of Final Research Achievements

This research aims to extend the frontier of small satellite activities to deep space, which has been expanding explosively in low Earth orbit, to realize truly high-frequency and flexible deep space exploration that can be carried out by anyone at any time, and to contribute to the advances in solar system science.
We have realized an orbit and attitude control system capable of driving a high thrust propulsion system to enable an ultra-small spacecraft that is equipped with an orbit transfer propulsion system capable of about 1 km/s acceleration, and that can head for deep space such as the Moon and Mars from a piggy-back launch to a geostationary transfer orbit (GTO) or lunar gateway. The feasibility of the proposed system was demonstrated through the design of a specific mission with a science payload on board.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は,近年爆発的に活用が広がっている低コスト・短期開発可能な超小型衛星の活動領域を,地球低軌道から月やそれ以遠の深宇宙へと拡大することにより,「深宇宙探査をいつでも誰でも実施可能」という真に高頻度で機動的な深宇宙探査の実現を目指すものであり,太陽系科学という学術分野の発展や深宇宙領域の民間活用に貢献することが期待される.
