On Monday, China achieved a significant milestone in its space exploration endeavors with the successful inaugural flight of the Long March 12B carrier rocket. This launch, which took place at the Jiuquan Satellite Launch Center, signifies a major leap forward in the nation’s space capabilities as the rocket managed to enter its designated orbit, deploying the 10th set of communication satellites for the Spacesail Constellation.
The Long March 12B, towering at approximately 72 meters, is now recognized as China’s most potent single-body rocket. The two-stage rocket is powered by ten engines fueled by liquid oxygen and kerosene, providing a thrust of around 800 metric tons at launch. This powerful configuration allows it to carry payloads exceeding 20 tons into low-Earth orbit. Development of this cutting-edge rocket commenced in September 2024, incorporating a range of advanced technologies aimed at enhancing performance and efficiency. Among these are high-performance propulsion systems, lightweight structural components, optimized fuel management systems, and sophisticated autonomous flight-control software capable of managing in-flight anomalies.
Looking ahead, engineers are setting their sights on future tests aimed at recovering and reusing the rocket’s first-stage booster. Should these efforts prove successful, a reusable version of the Long March 12B could be operational in the coming years, marking a new chapter in China’s space endeavors.
This mission has also contributed to the expansion of the Spacesail Constellation, which is a low-Earth-orbit satellite network designed to deliver high-speed global broadband internet services. To date, over 160 satellites have been launched for this ambitious project, which aims to deploy more than 10,000 satellites by the year 2030. The latest launch is a testament to China’s burgeoning commercial space sector and its aspirations to extend satellite internet coverage on a global scale.
