China has achieved a significant milestone in its space exploration efforts with the successful inaugural flight of the Long March 12B carrier rocket. Launched from the Jiuquan Satellite Launch Center, the rocket’s mission was a success as it reached its designated orbit, carrying and strategically deploying the 10th installment of the Spacesail Constellation communication satellites.
Standing at approximately 72 meters, the Long March 12B has emerged as China’s most robust single-body rocket to date. Equipped with a two-stage launch system, it is powered by an array of 10 engines that utilize liquid oxygen and kerosene, producing an impressive thrust of around 800 metric tons at liftoff. This enables the rocket to transport payloads exceeding 20 tons into low-Earth orbit.
The development of this advanced rocket system commenced in September 2024, with a focus on integrating cutting-edge technologies to enhance its performance and efficiency. This includes the use of high-performance propulsion systems, lightweight structural designs, optimized fuel management, and sophisticated autonomous flight-control software capable of addressing in-flight anomalies.
Future plans for the Long March 12B involve tests aimed at recovering and reusing its first-stage booster, with the potential to introduce a reusable version in the coming years. This development marks a notable step forward in China’s ambitions to create a sustainable and cost-effective space program.
The mission also plays a crucial role in expanding the Spacesail Constellation, a satellite network situated in low-Earth orbit designed to deliver high-speed broadband internet services globally. With over 160 satellites now deployed, the project aims to launch more than 10,000 satellites by 2030. This successful launch underscores China’s burgeoning commercial space industry and its determination to enhance satellite internet coverage worldwide.
