Mission Design for the TAIJI misson and Structure Formation in Early Universe Xuefei Gong, Shengnian Xu,Shanquan Gui, Shuanglin Huang and Yun-Kau Lau ∗ Abstract Gravitational wave detection in space promises to open a new window in astronomy to study the strong field dynamics of gravitational physics in astro- physics and cosmology. The present article is an extract of a report on a feasibility study of gravitational wave detection in space, commissioned by the National Space Science Center, Chinese Academy of Sciences almost a decade ago. The objective of the study was to explore various possible mission options to detect gravitational waves in space alternative to that of the (e)LISA mission concept and look into the requirements on the technological fronts. On the basis of relative merits and bal- ance between science and technological feasibility, a set of representative mission options were studied and in the end a mission design was recommended as the start- ing point for research and development in the Chinese Academy of Sciences.
