China's space ambitions are in full swing, with the recent announcement of the Long March 10C rocket's development as a commercial workhorse. This comes on the heels of a major achievement in reusable rocket technology, as China's China Academy of Launch Vehicle Technology (CALT) successfully recovered the first stage of the Long March 10B, a feat that has only been accomplished by SpaceX and China itself. This achievement is a testament to China's commitment to pushing the boundaries of space exploration and its determination to become a major player in the commercial space market.
The Long March 10C is set to be an all-methalox rocket, with both stages using reusable gas-generator methalox engines, designated YF-219. This design choice is significant as it allows for more efficient and powerful rocket systems, potentially surpassing the capabilities of the Long March 5B. The rocket's first stage will be larger and more powerful than the kerolox first stages of the Long March 10A and B, requiring a larger recovery vessel or a different approach to recovery. This expansion in capability is crucial for China's commercial launch, human spaceflight, and crewed lunar programs.
CALT researcher Qian Hang emphasizes the importance of modular design in the development of the Long March 10 series. The approach of using 'one diameter, two types of engines, and three modules' will significantly improve the efficiency of rocket manufacturing, assembly, testing, and launch. This modularization is a key strategy for China's space transportation industry, as it allows for faster and more cost-effective development and production.
The Long March 10C is positioned to be a mainstay commercial launcher, according to Yang Yuguang, Chairman of the Space Transportation Committee of the International Astronautical Federation. This designation is a testament to China's growing influence in the commercial space market and its ability to compete with established players like SpaceX. The rocket's development is a strategic move to boost the tonnage China can deploy to orbit, making megaconstellations and other large-scale space projects more viable.
China's efforts in reusable rocket technology are not limited to CALT. The Shanghai Academy of Spaceflight Technology (SAST) has developed the Long March 12A, a methalox rocket that reached orbit in its first launch in December 2025, albeit with a failed booster recovery attempt. SAST has also undergone recapitalization and restructuring, increasing its registered capital and investment, indicating a renewed focus on its reusable rocket program.
The competition is fierce, with China Commercial Rocket Co. Ltd., a subsidiary of SAST, developing the Long March 12B, a kerolox rocket that debuted in June without a recovery attempt. This highlights the diverse approaches China is taking to achieve its space goals. The country is also working on 7-meter-diameter reusable rockets as an intermediate step towards the super heavy-lift Long March 9, further showcasing its commitment to innovation and technological advancement.
In conclusion, China's space program is rapidly evolving, with a strong focus on reusable rocket technology and commercial space ventures. The development of the Long March 10C and the expansion of CALT's capabilities demonstrate China's determination to become a leading player in the global space industry. As China continues to invest in its space infrastructure and technology, the future of space exploration and commercial space ventures looks increasingly promising.
