China marked a significant milestone in its space exploration efforts with the successful maiden flight of the Long March 12B carrier rocket on Monday. This development underscores the nation’s advancing space capabilities as the rocket took off from the Jiuquan Satellite Launch Center, achieving its planned orbit and deploying the latest batch of Spacesail Constellation communication satellites.
The Long March 12B stands out as China’s most powerful single-body rocket to date, reaching a height of approximately 72 meters. This two-stage launch vehicle is equipped with 10 engines fueled by liquid oxygen and kerosene, collectively producing around 800 metric tons of thrust at liftoff. It boasts the capacity to transport over 20 tons of payload into low-Earth orbit, marking a significant engineering feat for the Chinese space program.
Initiated in September 2024, the development of the Long March 12B integrated cutting-edge technologies aimed at enhancing its performance and efficiency. Among these are high-performance propulsion components, lightweight structural materials, optimized fuel management systems, and advanced autonomous flight-control software designed to handle any anomalies during flight. Plans are underway for future tests focused on recovering and reusing the rocket’s first-stage booster, which could lead to the introduction of a reusable version of the Long March 12B in the years ahead.
This mission also contributed to the expansion of the Spacesail Constellation, a low-Earth-orbit satellite network intended to deliver high-speed global broadband internet services. With the latest deployment, the project has now launched more than 160 satellites, working towards its ambitious goal of deploying over 10,000 satellites by 2030. This endeavor not only highlights China’s growing footprint in the commercial space sector but also its aspirations to enhance satellite internet coverage worldwide.
