On Monday, China achieved a significant milestone in its space endeavors with the inaugural flight of the Long March 12B carrier rocket. This event, conducted at the Jiuquan Satellite Launch Center, underscores China’s rapid advancements in space technology. The rocket’s successful launch enabled it to enter the predetermined orbit, where it deployed the 10th batch of Spacesail Constellation communication satellites.
The Long March 12B is notable for its impressive stature, standing about 72 meters tall, making it the most powerful single-body rocket China has developed to date. The two-stage launch vehicle boasts 10 engines fueled by liquid oxygen and kerosene, generating roughly 800 metric tons of thrust during liftoff. It is capable of carrying over 20 tons of payload into low-Earth orbit, showcasing its robust payload capacity.
Development for this rocket began in September 2024, with engineers integrating a range of cutting-edge technologies aimed at enhancing its performance and efficiency. These innovations include advanced propulsion systems, lightweight structural components, optimized fuel management, and sophisticated autonomous flight-control software designed to address any anomalies during flight.
The engineering team is also planning subsequent tests focused on the recovery and reuse of the rocket’s first-stage booster. Should these tests prove successful, a reusable variant of the Long March 12B could be operational in the coming years, potentially marking a new era in China’s space exploration capabilities.
Furthermore, the mission contributed to the expansion of the Spacesail Constellation, an ambitious low-Earth-orbit satellite network set to offer high-speed global broadband internet services. With more than 160 satellites now in orbit, the project aims to deploy over 10,000 satellites by the end of the decade. This successful launch not only highlights the progress of China’s burgeoning commercial space sector but also aligns with its broader goal of enhancing global satellite internet coverage.
