On Monday, China marked a significant leap in its space exploration efforts with the inaugural flight of the Long March 12B carrier rocket. This advanced rocket was launched from the Jiuquan Satellite Launch Center and successfully placed its payload into the intended orbit, deploying the latest batch of Spacesail Constellation communication satellites.
The Long March 12B stands at approximately 72 meters tall and is currently the most powerful single-body rocket in China’s space fleet. This two-stage launch vehicle boasts 10 engines fueled by liquid oxygen and kerosene, producing around 800 metric tons of thrust at liftoff. It has the capability to transport over 20 tons of payload into low-Earth orbit, underscoring its formidable strength and efficiency.
Development on the Long March 12B commenced in September 2024, incorporating a range of cutting-edge technologies designed to enhance its performance. These advancements include high-performance propulsion systems, lightweight structural components, optimized fuel management, and autonomous flight-control software capable of addressing in-flight issues. Engineers are looking ahead to further testing aimed at achieving recovery and reuse of the rocket’s first-stage booster, which could lead to a reusable version of the rocket entering service in the near future.
This successful mission also bolsters the Spacesail Constellation project, a low-Earth-orbit satellite network intended to deliver high-speed global broadband internet services. With this launch, the project has now deployed over 160 satellites, moving closer to its ambitious goal of launching more than 10,000 satellites by 2030.
The successful flight of the Long March 12B showcases China’s growing prowess in the commercial space sector and its ongoing commitment to expanding global satellite internet access. This launch represents another milestone in the country’s efforts to enhance its capabilities in space technology and satellite communications.
