我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 core achievement of the Tianqin project is the successful detection of the new generation lunar laser retroreflector NGLR-1's echo signal, marking the first time Chinese scientists have detected this lunar laser reflector [1] - On August 13, the Tianqin station team obtained a total of 55 distance measurement values from the NGLR-1, confirming the success of the ranging experiment despite initial weather-related interruptions [1] - The successful detection provides crucial data for understanding gravity, spacetime, the moon's interior, and the evolution of the Earth-Moon system, contributing to a deeper understanding of the fundamental laws of the universe [1] Group 2 - The Tianqin project, proposed by Chinese Academy of Sciences academician Luo Jun in 2014, aims to deploy three satellites in Earth orbit by around 2035, forming an equilateral triangle constellation for space gravitational wave detection [2] - This recent achievement is part of the ongoing progress of the Tianqin project, which is focused on advanced research in fundamental physics, astrophysics, and cosmology [2]
