The Distributed and Intelligent Space System Lab (DSSL) at Tsinghua University held its 2025 Annual Research Summary Meeting, bringing together all laboratory members to review a year marked by rapid progress, expanding international engagement, and growing research depth.
Throughout 2025, DSSL remained highly active on the international stage. The laboratory participated in major academic forums ranging from the 5th China Aerospace Safety Conference in Harbin to the 76th International Astronautical Congress in Sydney. At the same time, DSSL hosted a series of high-level research exchanges in Beijing, including the National Key R&D Programme “Gravitational Wave Detection” project progress workshop, as well as a visit by Professor George Zhu, Academician of the Canadian Academy of Engineering, who toured the laboratory’s lunar robotics research platform.
Individual members of the laboratory also strengthened DSSL’s global academic footprint. Fang Zhengqing undertook a research exchange at Princeton University, while Kinthong Lee represented the laboratory at the Planetary Defense Conference (PDC) in South Africa, contributing to international discussions on planetary protection.
In terms of research output, DSSL achieved significant progress across a broad range of themes in space systems, astrodynamics, and intelligent spacecraft. Topics spanned risk assessment of satellite collisions in mega-constellations, low-thrust trajectory optimisation, multi-agent reinforcement learning for on-orbit cooperative control, asteroid deflection mission design, space-based gravitational wave observatories, spaceborne cooperative perception, and planetary surface vision and segmentation, alongside multiple international conference papers and newly granted patents.
To ensure close academic exchange within the laboratory, members delivered progress reports both on campus and at external venues, enabling continuous cross-fertilisation of ideas and strengthening collaboration across research directions.
The 2025 summary meeting concluded that DSSL has entered a phase of greater research depth, wider international visibility, and stronger interdisciplinary integration. With this momentum, the laboratory looks forward to a new year of expanded scientific ambition and innovation in 2026.
