China has taken a significant step forward in its space exploration efforts with the successful maiden flight of the Long March 12B carrier rocket. This launch, conducted on Monday from the Jiuquan Satellite Launch Center, marks a major milestone in the nation’s space capabilities. The rocket, standing approximately 72 meters tall, entered its designated orbit successfully, deploying the 10th batch of Spacesail Constellation communication satellites.
The Long March 12B is currently the most powerful single-body rocket in China’s arsenal. It features a two-stage launch vehicle powered by 10 engines fueled by liquid oxygen and kerosene, producing around 800 metric tons of thrust at liftoff. This enables the rocket to carry more than 20 tons of payload into low-Earth orbit. Development of this advanced rocket system began in September 2024, incorporating cutting-edge technologies such as high-performance propulsion components, lightweight structures, and autonomous flight-control software designed to handle in-flight anomalies.
Future plans for the Long March 12B include tests aimed at recovering and reusing its first-stage booster. If these tests are successful, a reusable variant of the rocket could be operational in the coming years. This would be a significant achievement, potentially reducing costs and increasing the frequency of launches.
The recent launch also contributes to the expansion of the Spacesail Constellation, a network of low-Earth-orbit satellites intended to deliver high-speed global broadband internet services. With the addition of this latest deployment, over 160 satellites have now been launched for the project, which is ambitiously targeting the deployment of more than 10,000 satellites by 2030.
This successful mission not only underscores China’s growing prowess in the commercial space sector but also highlights its ambitions to enhance global satellite internet coverage. The Long March 12B’s maiden flight is a testament to China’s commitment to advancing its position in the global space race.
