Successfully constructing a space station with three modules, China has ushered in a new era of exploration in lunar and deep space.

Recently, at the academic seminar on exploration and research of the Earth-Moon space using DRO technology, China announced the successful establishment of the world's first international Earth-Moon space three-star constellation based on DRO. The two satellites DRO-A/B developed and deployed by China have arrived and stationed in the distant retrograde orbit of the Earth-Moon space, and have established inter-satellite measurement communication links with the previously launched DRO-L near-Earth orbit satellite. This signifies that China has officially opened a new era of exploration in the Earth-Moon space.
