【Tech 24H】The Tianqin Laser Ranging Station at Sun Yat-sen University has achieved the first successful detection of echo signals from the next generation lunar laser retroreflector NGLR-1, obtaining multiple distance measurements. The solid monolithic NGLR-1 offers higher precision by eliminating distance broadening caused by lunar libration in previous reflectors, enabling advanced research in lunar physics, astrophysics, and cosmology.
