At 0338 Hours Hong Kong SAR- Beijing Time9 April 2026 , China- People’s Republic of China- CNSA –China National Space Administration Successfully launched Chang Zheng – Long March 6A yao 17 Carrier Rocket ignited and took off at the Taiyuan Satellite Launch Center Shanxi Province.. China successfully launched the 21st low-Earth orbit satellite internet constellation from the Taiyuan Satellite Launch Center using a Long March-6A carrier rocket. This launch was the 81st space launch globally in 2026, China’s 21st (3rd this month), the 6th launch by the Eighth Academy of Aerospace Science and Technology, and the 3rd launch by the Long March-6A rocket
The Long March 6A rocket, developed by the Eighth Academy of China Aerospace Science and Technology Corporation, is China’s first solid-liquid coupled launch vehicle, capable of launching single, dual, triple, or stacked satellites …
I. Core Technologies and Positioning
- The Long March 6A, the first solid-liquid hybrid rocket
, is China’s only medium-lift rocket to adopt a “liquid core stage + solid booster” configuration.- Core-level power : Equipped with two liquid oxygen and kerosene engines (non-toxic and pollution-free), providing stable thrust for extended range;
- Solid propulsion : It is equipped with four solid rocket motors with a diameter of 2 meters, each with a thrust of 120 tons and an ignition response of only milliseconds, which significantly improves the initial thrust.@China Aerospace Science and Technology Corporation…
- Carrying capacity : ≥4.5 tons for 700 km sun-synchronous orbit, and up to 6.5 tons for 500 km orbit.@Beijing Blue Dragon31
- It can flexibly adapt to the needs of multiple missions
and supports various launch configurations such as single satellite, dual satellite, three satellites, stacking, and wall mounting. It can be adapted to diverse payloads such as remote sensing satellites and communication constellations. For example, the Qianfan constellation was once deployed in the form of “18 satellites in one launch”.@Science and Technology Power1 - Breakthroughs in intelligence and security
- For the first time in China, online fault diagnosis and adaptive reconfiguration technology for servo systems has been adopted, enabling automatic adjustment of control commands during flight.
- The health diagnostic system completes engine status analysis within 0.3 seconds and automatically stops ignition if an abnormality is detected.
- The system enables unattended launches, with personnel evacuated four hours before the mission and the system taking over remotely.
2 Application Scenarios and Strategic Value
- The core carrier of the satellite internet network
is responsible for the networking mission of China’s “Government Grid Constellation” (GW constellation), which is planned to have 13,000 satellites and provide global coverage 6G communication services. More than 50 satellites will be launched by 2025, and the core backbone network is planned to be completed by the end of 2026.2734 - Military-civilian integration and industrial empowerment
- Civilian applications : Supporting national land surveys, crop yield estimation, and disaster prevention and mitigation (such as real-time monitoring of floods);31
- Military potential : Low-Earth orbit satellites can provide encrypted communication and high-precision navigation correction, enabling a “detect and strike” combat mode;
- Commercial spaceflight : Reduce the cost of a single launch by 30% and promote the localization of satellite manufacturing (such as phased array antennas being 100% domestically controlled).
- The environmentally friendly and sustainable design
uses green propellants, with emissions mainly consisting of water vapor and carbon dioxide; the satellite is equipped with a thin-film deorbit sail, which will burn up in the atmosphere within 3 months after the end of its lifespan, reducing space debris.
IV. Public Concerns and Future Challenges
- Spaceflight
has created numerous astronomical phenomena, including the “twilight effect” and “rocket piercing the moon.” In June 2025, observers in Xi’an captured images of a giant scattering cloud ejected from a rocket in the morning light.4 - International competition and technological iteration
- Advantages : Mature solid-liquid bonding technology (100% success rate), modular design supports rapid integration;
- Challenges : Facing SpaceX’s rocket recovery technology, the development of reusable rockets needs to be accelerated; the international launch market is constrained by geopolitics.
With its “cross-domain propulsion” and mission adaptability, the Long March 6 rocket has become the backbone of China’s high-density space launches and will continue to support the country’s space infrastructure and global competition for low-Earth orbit resources in the future.
