In mid-October 2025, China's Space Pioneer commercial aerospace firm secured around $350 million in new funding rounds to support its reusable Tianlong-3 rocket and next-generation launch vehicle and engine development. Space Pioneer also completed separation tests for 36 satellites via its Tianlong-3 (TL-3) carrier rocket in Zhangjiagang, East China's Jiangsu Province this month, marking a key breakthrough in China's commercial aerospace sector, particularly in multi-satellite deployment and heavy-lift capabilities. The test, combined with other new technologies, brings the TL-3's reliability and cost efficiency up to competitive world-class standards. Space Pioneer's TL-3 aims to provide reliable, efficient, and low-cost launch services for low-Earth orbit (LEO) satellite constellation missions, accelerating the development of China's space infrastructure.
Tianlong-3 is a two-stage kerosene and liquid oxygen-fueled (kerolox) launch vehicle with a reusable first stage made of high-strength stainless steel. The TL-3 carrier rocket, capable of delivering over 20 tons of cargo into LEO, integrates more than 50 key technologies—30 are being applied for the first time. In July 2025, Space Pioneer completed construction of its Tianlong-3 rocket launch pad at the Jiuquan Satellite Launch Center (JSLC) in northwestern China.
Unlike traditional multi-satellite separation systems that rely on explosive bolts or pyrotechnic devices that are costly, high-risk, and that can cause strong impacts and contamination of the carrier rocket—this new design uses a shape-memory alloy unlocking mechanism. The test verified the new design's accuracy and reliability, achieving a 90 percent reduction in impact force, a 60 percent reduction in weight, zero emissions and only 30 percent of the traditional system's cost, according to the company.
Space Pioneer, also known as Beijing Tianbing Technology Co., Ltd., has achieved an annual production capacity of 30 TL-3 rockets and 500 TH series engines. The company plans to carry out TL-3's maiden flight by the end of 2025 and gradually support more than 60 launches per year, providing critical launch capacity for China's satellite internet infrastructure.
In 2023, Space Pioneer's Tianlong-2 rocket became China's first commercial liquid-fueled launch vehicle to reach Earth orbit.
China has been ramping up the construction of LEO constellations. On October 17, 2025 China sent 18 satellites into scheduled orbit, constituting the Spacesail Constellation—a commercial Chinese low-orbit satellite network, according to China's Ministry of Industry and Information Technology (MIIT).
Meanwhile, the Zhuque-3 reusable rocket, developed by Chinese private space firm LandSpace, successfully completed its fueling rehearsal and static ignition test on October 21, 2025, marking an entry into the critical preparation phase for its maiden flight, and it is also expected to support China's large-scale constellation deployment.
