The reporter learned from the Space Application Engineering and Technology Center of the Chinese Academy of Sciences that recently, China made an important breakthrough in the Earth-Moon laser communication test mission, successfully established a bidirectional laser link at a distance of more than 400,000 kilometers, and realized two-way high-speed laser communication between the Earth and the Moon for the first time. This marks the official transition of China's space laser communication from low-Earth orbit into Earth-Moon space.
