Abstract

Chinese Space-borne Gravitational Wave Detection Program “Taiji” is to detect the gravitational wave(GW)within the frequency band between 0.1 mHz and 1 Hz. The GW sources in such frequency band offer a brand new approach to study our universe,the supper massive black holes,the nature of gravity,the dark matter and the dark energy. The technologies related to Taiji program are so challenging that Taiji have to take three steps,“single satellite”,“double satellites” and “three satellites”,to achieve the final objectives. The “single satellite” mission,called Taiji-1,is now successfully launched,and the first run of on-orbit testing is completed. A brief review of the scientific influences,the recent status and the anatomy of key technologies of the space-borne GW detection missions are given. The mission overview and the 3-step strategic planning of Taiji program are analyzed. The future perspectives and some advices concerned with Taiji program are also discussed.
