Abstract：

The Taiji program is a space-based gravitational-wave observatory targeting the 0.1 mHz–1.0 Hz frequency band via a triangular constellation of three Sun-orbiting spacecraft. Its scientific case encompasses the observation of supermassive and intermediate-mass black-hole mergers, extreme and intermediate-mass-ratio inspirals, the formation and cosmological evolution of massive black holes, and the probing of fundamental gravity, spacetime structure, and the dark Universe. This talk delivers a concise mission overview, addressing the primary science objectives and the payload configuration. Special attention is devoted to the program's development roadmap, covering key in orbit validation outcomes from the Taiji-1 mission, the current mission status, and the strategic vision toward full constellation deployment.

CV：Luo Ziren is Professor Researcher of Institute of Mechanics, CAS. Executive Director of the Gravitational Wave Experimental Center. Dr. Luo has been dedicated to space gravitational wave detection and precision laser metrology research since 2007. He once served as the Chief Designer of the core measurement subsystem for China’s Taiji-1 technology demonstration satellite, and led the in-orbit realization of China’s first hundred-picometer-level laser interferometry precision in 2019. He is currently the Chief Scientist of the national key R&D program “System Analysis and Design of Inter-satellite Laser Interferometry”, and Chief Scientist Assistant for the Taiji-2 mission, leading the development of key interferometer prototypes and core technical system construction for the next-generation space gravitational wave detection program.
