<\/p>\nChina has formally launched the International Earth-Moon CubeSat Constellation Big Science Program, which aims to deploy 30 CubeSats across cislunar space in six batches. The preliminary schedule targets the completion of all launches and deployments around 2030. The satellites will conduct space-environment monitoring, gamma-ray burst observations and lunar-resource surveys, generating data intended to support future crewed lunar missions and lunar base development.<\/p>\n
<\/p>\n
The constellation will consist of 12U CubeSats weighing no more than 30 kilograms each. They are planned for deployment into 1:3 Earth-Moon resonant highly elliptical orbits, in which the spacecraft will travel between a near-Earth perigee and an apogee approaching the Moon. The orbital design will use Earth-Moon gravitational resonance to support long-duration operations.<\/p>\n
The Earth-Moon region extends from low Earth orbit to approximately 2 million kilometers from Earth. It is emerging as a key operating area for future crewed lunar missions, lunar-orbit transportation systems and permanent lunar infrastructure.<\/p>\n
Under the current plan, the 30 satellites will be divided into two groups: space-environment monitoring spacecraft and gamma-ray burst detection spacecraft. By observing events from multiple locations at the same time, the constellation is expected to capture their evolution more completely than isolated spacecraft can. Its gamma-ray burst observations are intended to improve burst-localization accuracy to the sub-arcsecond level,which is a breakthrough accuracy in the history of human astronomical observation.<\/p>\n
The project would shift cislunar exploration from what researchers describe as an intermittent, single-point observation model to a networked and more continuous monitoring model. Put simply, it aims to replace the equivalent of shining a flashlight into space with turning on a network of streetlights.<\/p>\n
One of the constellation\u2019s most direct applications is monitoring the space environment around future crewed missions. Solar activity can produce elevated radiation, energetic-particle events and disturbances that affect spacecraft electronics, communications and human health.<\/p>\n
For a lunar base, such information could support decisions about when astronauts should conduct extravehicular activities, when sensitive equipment should be placed in a safe configuration and when crews should move into better-shielded areas. It could also help mission controllers assess risks during spacecraft transfers, lunar landings and ascent operations.<\/p>\n
The satellites are also expected to support lunar-resource exploration. Their data would not replace dedicated resource-mapping missions, but could contribute to a broader information system for selecting landing sites, planning surface operations and understanding the environment in which future infrastructure will operate.<\/p>\n
As with terrestrial weather forecasting, useful space-weather services would require more than raw observations. Data from the CubeSat constellation would need to be combined with solar observations, propagation models and ground-based analysis. The mission could therefore become an early component of a future Earth-Moon space-environment forecasting system.<\/p>\n
The future lunar economy will also require navigation and communications infrastructure located closer to the Moon. At present, many lunar missions depend on tracking, navigation and communications services based on Earth, roughly 380,000 kilometers away.<\/p>\n
That approach remains effective for individual missions, but it becomes more difficult as traffic increases and operations become more complex. For example, in the past, whether it was landing and taking off on the lunar surface, or rendezvous and docking in the lunar orbit, all of these operations relied on navigation and positioning services provided by the Earth, which was as far as 380,000 kilometers away, resulting in extremely low accuracy and great difficulties. A dedicated navigation constellation near the Moon could provide positioning, navigation and timing services for lunar landings, ascent operations, orbital rendezvous and docking. Local navigation support could make these activities more accurate, safer, and less dependent on continuous assistance from Earth. Furthermore, it offers a more cost-effective solution, which is essential for future large-scale lunar exploration and development.\u00a0<\/span><\/span><\/span><\/p>\n The Earth-Moon CubeSat constellation is not itself a lunar navigation network. Its role is primarily scientific and environmental. However, operating multiple small spacecraft in cislunar space would help develop experience in constellation coordination, long-distance communications, autonomous operations and deep-space mission control\u2014capabilities that could later support dedicated navigation systems.<\/p>\n In the future, as human exploitation of the Moon increases, communication between the Earth and the Moon will also become extremely urgent. We need to further master technologies including high-capacity laser communication, so that the bandwidth of round-trip data between the Earth and the Moon can be increased by orders of magnitude, meeting the needs of various future lunar exploration and development activities. Although such systems require extremely precise pointing, acquisition and tracking.<\/p>\n The program was jointly initiated by the Deep Space Exploration Laboratory and the International Deep Space Exploration Association, with support from the Asia-Pacific Space Cooperation Organization.<\/p>\n Its cooperation framework is based on four principles: joint design<\/strong>, free launch opportunities<\/strong>, shared financial responsibilities<\/strong> and scientific-data sharing<\/strong>. The Chinese side is responsible for the unified development of three sets of standard payloads, namely high-energy particle imager, space magnetometer and gamma-ray burst detector, and will provide them to partners free of charge.<\/p>\n China provides the core technical payload, partner countries offer the satellite platform and launch services, and all parties share the data.<\/strong> The program will also provide technical training and establish standardized interface specifications to help developing countries participate more deeply in deep-space exploration.<\/p>\n Thailand, Serbia, Egypt, Senegal and Indonesia are among the countries whose research institutions have joined the initiative. The first phase of engineering development has begun, with system-level studies covering satellites, payloads and ground control expected to conclude soon.<\/p>\n The mission\u2019s technical requirements could stimulate China\u2019s CubeSat supply chain. Cislunar spacecraft must withstand a more demanding radiation environment and operate under more difficult communications, navigation and mission-control conditions than typical low Earth orbit CubeSats. Meeting those requirements could accelerate the transition of domestic CubeSat manufacturing from laboratory-scale prototypes toward more standardized industrial production.<\/p>\n The China Computer Industry Association\u2019s Space Computing Working Committee has also reported that more than 100 organizations have applied to join, indicating an emerging industrial ecosystem around space computing and small spacecraft.<\/p>\n The constellation has sometimes been described as a \u201cspace-based Starlink\u201d because both concepts involve multiple satellites operating as a network. The comparison is useful for explaining the basic idea, but the two systems serve fundamentally different purposes.<\/p>\n SpaceX\u2019s Starlink is a large low Earth orbit communications network designed primarily to provide internet access to users on the ground. Its satellites support broadband connectivity, and its value comes from the scale and capacity of the communications network.<\/p>\n The International Earth-Moon CubeSat Constellation is intended mainly to serve space-based scientific exploration and future activity in the Earth-Moon system. Its satellites will monitor the space environment, detect high-energy astronomical events and collect data relevant to lunar exploration. It is not a terrestrial internet network and is not intended to provide routine broadband service to ground users.<\/p>\n The difference can also be understood in terms of infrastructure priorities. Starlink is optimized for high-throughput communications in low Earth orbit, while the Earth-Moon constellation is focused on distributed scientific sensing in a much larger and more challenging operational environment.<\/p>\n The significance of the International Lunar Cube Constellation does not lie in the 30 satellites themselves, but in the fact that it proves one thing: China is taking the approach of “international cooperation + technology export + data sharing” to proactively lay out infrastructure in cislunar space, the new frontier of human activities in the future, in the hope that this region will play an even more important role in humanity’s future voyages to the deeper reaches of the universe.<\/p>\n The same trends behind this program\u2014standardized spacecraft, lower-cost payloads and expanding satellite manufacturing capacity\u2014are also broadening access to Earth-observation services. China\u2019s growing space industry is bringing more satellite platforms and payload capabilities to the global market, creating increasingly competitive options for international customers.<\/p>\n STARPATH GLOBAL helps organizations select satellite imagery according to their actual industry requirements, including a resolution that is sufficient for the task without creating unnecessary cost.
