中国科学家首次探测到月球新一代激光反射镜回波信号

Group 1 - The successful detection of the new generation lunar laser retroreflector NGLR-1 by the Sun Yat-sen University Tianqin Station marks China's achievement in lunar laser measurement, making it the fourth country to accomplish this after France, Germany, and the United States [1][3] - The Tianqin team initially obtained 17 distance measurement values and later confirmed the success of the measurement by acquiring 38 additional values, despite weather interruptions [3] - The NGLR-1 retroreflector, unlike its predecessors, is a solid 10-centimeter diameter object, which increases measurement precision and reduces distance broadening effects caused by lunar libration [4] Group 2 - The Tianqin project, proposed by Chinese Academy of Sciences academician Luo Jun in 2014, aims to establish a space gravitational wave observatory by deploying three satellites in a triangular formation by around 2035 [4] - The successful measurement of the NGLR-1 contributes to the ongoing progress of the Tianqin project, which supports long-term research in lunar physics, astrophysics, and cosmology [4]
