AbstractIn this perspective, we outline that a space borne gravitational wave detector network combining LISA and Taiji can be used to measure the Hubble constant with an uncertainty less than 0.5% in ten years, compared with the network of the ground based gravitational wave detectors which can measure the Hubble constant within a 2% uncertainty in the next five years by the standard siren method. Taiji is a Chinese space borne gravitational wave detection mission planned for launch in the early 2030 s. The pilot satellite mission Taiji-1 has been launched in August 2019 to verify the feasibility of Taiji. The results of a few technologies tested on Taiji-1 are presented in this paper.

Theory Of Gravity

The generation of massive Gravitational Waves (GW) from metric f(R) theory of gravity is studied and the sensitivity of a spherical antenna detector towards such a wave is looked into. The energy sensitivity is maximum for the monopole mode of the sphere. Of the five quadrupole modes of a sphere, only three are triggered by a massive wave. Also, the sensitivity of a spherical antenna with mechanical resonators attached to it is studied. The Truncated Icosahedral Gravitational wave Antenna (TIGA), originally proposed for detecting the effect of massless GW on the quadrupole modes of a sphere, has been modified in this paper to get a Modified TIGA, in order to detect the sensitivity of monopole modes towards a massive wave.

The microthruster is the crucial device of the drag-free attitude control system, essential for the space-borne gravitational wave detection mission. The cusped field thruster (also called the High Efficiency Multistage Plasma Thruster) becomes one of the candidate thrusters for the mission due to its low complexity and potential long life over a wide range of thrust. However, the prescribed minimum of thrust and thrust noise are considerable obstacles to downscaling works on cusped field thrusters. This article reviews the development of the low power cusped field thruster at the Harbin Institute of Technology since 2012, including the design of prototypes, experimental investigations and simulation studies. Progress has been made on the downscaling of cusped field thrusters, and a new concept of microwave discharge cusped field thruster has been introduced.
