On June 20, at the Dongfeng test center, LandSpace successfully executed the ground validation of the Zhuque-3 rocket propulsion system, configured with nine Tianque-12A engines operating in parallel. This test constitutes the most complex and automated ground test conducted to date in China using liquid methane and oxygen as propellants.
This was the test of the Zhuque-3 rocket.
The staggered ignition of the engines, which reached a total thrust of 7542 kN, was followed by 45 seconds of continuous operation and a servo oscillation test. The procedure closely replicated the conditions of the planned first flight, including cryogenic filling, tank pressurization, soft start and scheduled shutdown.

Through this execution, LandSpace demonstrated end-to-end compatibility between the systems involved: from avionics and structure, to propellant delivery and ground support systems. This precise integration represents a key step towards the commercial launch of reusable rockets.
The Zhuque-3, made of stainless steel structure, is 66 meters long and weighs about 570 tons at takeoff. It is designed to be reusable in its first stage, through vertical recovery guided by grid fins and an auxiliary power system.
Real flight simulation
The test station used was specifically adapted for this campaign, incorporating specialized test benches and remote and emergency control mechanisms. This environment allowed to simulate with high fidelity the real flight environment and to strengthen operational safety.
The test strengthens China’s position in the race for reusable rocket development reusable methane-powered rockets methane-powered reusable rockets, a technology that promises to significantly reduce launch costs. The Zhuque-3 is projected as a key platform for low-orbit satellite constellation services and high-frequency missions.
With this validation completed, LandSpace is approaching its first flight and consolidates its ability to operate in the competitive commercial aerospace sector, positioning itself alongside other global players in reusable launcher technology.
