In a significant leap forward for its space endeavors, China successfully launched the Long March 12B carrier rocket on Monday, underscoring the nation’s growing capabilities in space exploration. The rocket’s maiden flight took place at the Jiuquan Satellite Launch Center, where it ascended into its designated orbit and deployed the latest addition to the Spacesail Constellation communication satellites.
Measuring approximately 72 meters in height, the Long March 12B is now China’s most formidable single-body rocket. The two-stage vehicle is equipped with ten engines fueled by liquid oxygen and kerosene, delivering an impressive thrust of around 800 metric tons during liftoff. This powerful configuration allows the rocket to transport payloads exceeding 20 tons into low-Earth orbit.
The development of the Long March 12B began in September 2024, with engineers integrating cutting-edge technologies to enhance its performance and efficiency. Among these innovations are high-performance propulsion systems, lightweight structural elements, sophisticated fuel management, and autonomous flight-control software designed to address anomalies during flight. Looking ahead, engineers are preparing for future tests aimed at recovering and reusing the rocket’s first-stage booster, which could pave the way for a reusable version in the years to come.
This mission also marked an expansion of the Spacesail Constellation, a satellite network operating in low-Earth orbit with the goal of delivering high-speed global broadband internet. To date, the initiative has successfully launched more than 160 satellites, with an ambitious plan to deploy over 10,000 by the year 2030.
The successful deployment of the Long March 12B represents a critical milestone for China’s burgeoning commercial space sector, reinforcing the country’s ambitions to enhance global satellite internet coverage. As China continues to advance its space technology, the achievement not only highlights a significant technological development but also positions the nation as a key player in the global space race.
