In the early morning of August 21, Beijing time, the international academic journal classic quantum gravity published the results of the first round of experiments on the tianqin-1 experimental satellite. According to the paper, the experimental results show that all technical indicators of tianqin-1 in orbit verification not only exceed the expected target of the mission, but also exceed the highest level of similar technologies in China. Some technical indicators are two orders of magnitude higher than the existing domestic indicators. Luo Jun, academician of the Chinese Academy of Sciences and chief scientist of China’s “tianqin project”, said that the core task of “tianqin-1” is to verify the space inertial reference technology, which is one of the core technologies in the space gravitational wave detection technology system, including three key technologies of high-precision inertial sensing, micro cow level continuous adjustable micro propulsion and non drag control, and High precision laser interferometry technology, high stability temperature control technology and high precision centroid control technology. According to Ye Xianji, Professor of the tianqin center of Sun Yat sen University, the project was officially approved by the National Space Administration in October 2018, and successfully launched in Taiyuan, Shanxi Province on December 20, 2019, undertaking the on orbit verification task of the six major technologies of the “tianqin program”. According to relevant experts from the tianqin center of Sun Yat sen University, half a year after the launch of the tianqin-1 test satellite, all the six technologies of tianqin-1 have been verified in orbit, and each technical index is better than the mission objective. According to the introduction, classics and quantum gravity was first published in 1984. It is a well-known international journal in the field of gravity and relativity. It mainly deals with the research directions of quantum gravity, modified gravity theory and its experimental test. < / P > < p > “tianqin No.1” is an important part of the “0123” technology roadmap of tianqin project. The technical route of tianqin project is characterized by: on the one hand, each step of the mission has its own scientific output or major application; on the other hand, it promotes the key technology of space gravitational wave detection to mature in stages, so as to ensure the final development of the space gravitational wave detection mission. < / P > < p > < p > “tianqin project” is a major scientific plan for space gravitational wave detection in China, which was proposed by Luo Jun, academician of the Chinese Academy of Sciences in March 2014. Its scientific purpose is to conduct advanced research on astronomy, cosmology and basic physics through gravitational wave detection. It is estimated that around 2035, three identical satellites will be deployed to form an equilateral triangle formation with a side length of about 170000 km. A space gravitational wave observation Observatory will be built to carry out frontier research on space basic science.
