China is making significant strides in cislunar space with its “Cislunar Information Superhighway.”
This 30-satellite network aims to provide real-time communication, navigation, and monitoring services between Earth and the moon.
It marks a crucial step toward expanding human activities and intensifying global space competition.
The Vision Behind the Cislunar Information Superhighway
The China Academy of Space Technology (CAST) and the Beijing Institute of Spacecraft System Engineering are leading this initiative.
The “Cislunar Information Superhighway” will allow up to 20 travelers to communicate with Earth through images, audio, and video. Furthermore, it will offer precise positioning, navigation, and timing (PNT) for Earth-moon missions and lunar operations.
Yang Mengfei, chief designer of China’s Chang’e-5 mission, emphasizes the growing importance of cislunar space. He notes, “Activities in this region are expected to expand rapidly over the next decade, fueling a new wave of global competition.”
In particular, cislunar space includes satellite orbits around Earth, the area within the moon’s orbit, and the space in betweeen.
Stages of Development
China’s cislunar infrastructure will develop in three stages:
- Initial Phase: Two satellites and a lunar control station will support communication for up to 10 users.
- Expansion Phase: Ten more satellites and a second lunar station will be added. This will increase data rates to 5 gigabytes per second and improve navigation accuracy to 100 meters.
- Final Phase: The network will expand to 30 satellites and three lunar stations. This phase aims for data rates of 10 gigabytes per second and 10-meter navigation accuracy for lunar activities, and 50 meters for Earth-moon travel.
This project not only enhances China’s technological capabilities but also secures critical orbital slots and radio frequencies. Additionally, the global competition includes similar projects from the United States, Europe, and Japan, all focusing on scientific exploration and commercial operations on the moon.
The Cislunar Information Superhighway
The development of this satellite network highlights the increasing importance of cislunar space, not just for scientific exploration but also for military and commercial activities.
For instance, the United States Air Force is developing the Cislunar Highway Patrol System, designed to monitor objects at lunar distances.
As countries compete for dominance, the establishment of cislunar infrastructure becomes crucial for future space missions, including crewed lunar landings and the construction of international lunar research stations.
