The growing demand for reusable space transportation systems underscores the importance of developing reliable recovery technologies for space vehicles, particularly launcher stages. This paper presents an actively controlled parafoil system designed to enhance landing precision, building on the legacy of the Space Rider (SR) mission. The system integrates modern navigation methods, optimization-based guidance, and robust control strategies. It consists of a parafoil attached to a recoverable payload, operating in cooperation with a sea-drone platform. This cooperative scheme reduces the required landing area and mitigates impact energy constraints by using a net-based absorption mechanism. To assess feasibility, a high-fidelity simulation environment was developed, enabling the evaluation of landing accuracy and touchdown velocity, among other requirements. The results confirm the viability of the proposed approach and highlight key challenges for future development and maturation.
