China has established the world's first three-satellite constellation in the distant retrograde orbit (DRO) within the Earth-moon region, connecting them with stable inter-satellite links. This achievement, according to the Chinese Academy of Sciences (CAS), has yielded significant scientific and technological advancements, laying a foundation for future space exploration.
The Earth-moon region, extending up to 2 million kilometers from Earth, offers vast potential for lunar resource exploitation and interplanetary activities. The project, initiated in 2017, saw the launch of the satellites in 2024, forming the constellation.
Chinese scientists achieved breakthroughs, including the world's first low-energy DRO insertion and the successful verification of a long-distance inter-satellite communication link. The mission also supported astrophysical research and validated a new space-based orbit determination system, significantly reducing costs.
This program will support future lunar exploration missions, providing navigation services and high-precision time signals. The DRO's location will also facilitate communication with lunar spacecraft.
