China has achieved a significant breakthrough in its space exploration endeavors with the successful inaugural launch of the Long March 12B carrier rocket. This event, which took place on Monday, underscores the country’s expanding capabilities in space technology.
The launch occurred at the Jiuquan Satellite Launch Center, where the rocket ascended and successfully positioned its payload into the predetermined orbit. This mission included the deployment of the 10th batch of the Spacesail Constellation communication satellites, advancing China’s satellite internet infrastructure.
The Long March 12B stands as China’s most formidable single-body rocket to date, reaching a height of approximately 72 meters. It is a two-stage launch vehicle powered by ten engines using liquid oxygen and kerosene, generating around 800 metric tons of thrust at liftoff. This powerful rocket can carry payloads exceeding 20 tons into low-Earth orbit, showcasing its significant capacity.
Development of this advanced rocket commenced in September 2024, integrating cutting-edge technologies aimed at enhancing performance and efficiency. These advancements include high-performance engines, lightweight structural materials, optimized fuel systems, and autonomous flight control software capable of addressing in-flight issues.
Plans are underway for future testing to recover and reuse the rocket’s first-stage booster, potentially leading to a reusable version of the Long March 12B in the years to come. This mission also marked a step forward for the Spacesail Constellation initiative, which seeks to establish a global broadband internet network through low-Earth-orbit satellites. With more than 160 satellites already in orbit, the project aims to deploy over 10,000 satellites by 2030. The successful launch is another stride in China’s growing commercial space sector and its efforts to enhance worldwide satellite internet access.
