China has reached a significant milestone in its space exploration efforts with the successful maiden flight of the Long March 12B carrier rocket. The launch occurred on Monday at the Jiuquan Satellite Launch Center, where the rocket achieved its intended orbit and deployed the 10th batch of Spacesail Constellation communication satellites. This achievement marks a notable advancement in China’s space capabilities, showcasing the potential of its latest and most powerful single-body rocket.
The Long March 12B, standing approximately 72 meters tall, is a two-stage launch vehicle powered by 10 engines fueled by liquid oxygen and kerosene. This configuration generates an impressive 800 metric tons of thrust at liftoff, enabling the rocket to transport over 20 tons of payload into low-Earth orbit. The development of the rocket started in September 2024, with engineers integrating cutting-edge technologies to enhance its performance and efficiency. These innovations include advanced propulsion components, lightweight structures, optimized fuel management, and autonomous flight-control software designed to handle in-flight anomalies.
Future plans for the Long March 12B involve tests to recover and reuse its first-stage booster. Should these tests prove successful, a reusable version of the rocket could be operational in the coming years, further advancing China’s space capabilities and sustainability efforts.
This successful launch also supports the expansion of the Spacesail Constellation, a satellite network aimed at delivering high-speed global broadband internet services. With over 160 satellites already launched for the project, the goal is to deploy more than 10,000 satellites by the year 2030, significantly increasing global satellite internet coverage.
Overall, the successful maiden flight of the Long March 12B rocket represents a critical step forward for China’s burgeoning commercial space sector and highlights the nation’s ambitions to enhance its presence in global satellite communications.
