"LandSpace's Zhuque-3 Y1 Carrier Rocket Completes First Phase of Flight Test Mission | Xinxing PORTFOLIO"

The Ultimate Journey Begins Now

From October 18 to 20, 2025, LandSpace's Zhuque-3 Y1 carrier rocket completed the first phase of its maiden flight mission at the liquid oxygen-methane Rocket Launch Pad No. 2 in the Dongfeng Commercial Space Innovation Test Zone — propellant loading rehearsal and static fire test. Vertical operations drills will follow per schedule, after which the rocket will return to the technical area to prepare for the orbital launch and first-stage recovery.

The Zhuque-3 maiden flight test mission is divided into two phases: Phase one covers propellant loading rehearsal and static fire testing, followed by return to the technical area for inspection and maintenance; Phase two targets orbital launch as its primary mission objective, with simultaneous attempt at first-stage recovery. This test covered the full process including horizontal transfer and erection of the complete rocket, full subcooled propellant loading, integrated launch-test operations, nine-engine ignition and hold-down, and propellant drain, comprehensively validating the rationality of the launch-test workflow and the compatibility between the rocket system and launch site system.

The Zhuque-3 (ZQ-3) was formally approved in August 2023. Developed independently by LandSpace for large-scale constellation deployment missions, it is a high-capacity, low-cost, reusable large liquid-propellant carrier rocket. The rocket's first and second stages have a diameter of 4.5 meters, the fairing is 5.2 meters in diameter, the total length is 66.1 meters, the liftoff mass is approximately 570 metric tons, and the liftoff thrust exceeds 750 metric tons. The rocket uses stainless steel as the primary structural material for its body. The first stage is equipped with nine TQ-12A liquid oxygen-methane engines, along with RCS thrusters, grid fins, and landing legs required for stage recovery. After completing orbital launch missions, it can autonomously return with high precision and achieve a soft landing at the recovery site for reuse.

LandSpace always places flight safety and technical reliability above all else, maintaining a pragmatic and steady work pace, meeting every challenge with rationality and responsibility. Following the Zhuque-3 first-stage propulsion system test in June this year, this phase represents the final major ground test before launch. Going forward, LandSpace will conduct reviews based on test data, further refine procedures and contingency plans, and steadily advance Phase two work while ensuring quality and safety, striving for complete success in both test objectives and taking a solid step toward the engineering application and scaled development of reusable rockets.
