On Monday, China achieved a significant milestone in its space exploration program with the inaugural launch of the Long March 12B carrier rocket. This event signifies a considerable leap in the nation’s space capabilities as the rocket successfully lifted off from the Jiuquan Satellite Launch Center, delivered its payload into the intended orbit, and released the 10th batch of Spacesail Constellation communication satellites.
The Long March 12B, standing at approximately 72 meters, is recognized as China’s most robust single-body rocket to date. With a two-stage design, it utilizes 10 liquid oxygen and kerosene-fueled engines, producing around 800 metric tons of thrust at launch. This formidable power enables the rocket to transport payloads exceeding 20 tons into low-Earth orbit.
Development of this advanced rocket commenced in September 2024, incorporating cutting-edge technologies designed to enhance its performance and efficiency. Key innovations include high-performance propulsion systems, lightweight structural components, streamlined fuel management, and advanced autonomous flight-control software, which can address in-flight anomalies autonomously. Engineers are now focused on future testing phases that aim to achieve the recovery and reuse of the rocket’s first-stage booster, potentially leading to a reusable model of the Long March 12B in the near future.
The mission also contributed to the expansion of the Spacesail Constellation, a network of low-Earth-orbit satellites intended to deliver high-speed global broadband internet services. With over 160 satellites now deployed, this ambitious project plans to launch more than 10,000 satellites by the year 2030. This successful launch underscores China’s burgeoning commercial space industry and its strategic goal to broaden satellite internet coverage worldwide.
