The mission delivered an entire satellite group on a single flight, enabling Qianfan to add orbital capacity through a coordinated batch deployment. Multi-satellite launches are particularly important for large constellations because they can reduce deployment costs, simplify launch procurement and accelerate the establishment or replenishment of orbital planes.
For LandSpace, the flight demonstrated the improved Zhuque-2’s ability to support routine constellation missions involving multiple spacecraft and a coordinated orbital insertion. Reliable access to batch launches is becoming increasingly important as Chinese satellite operators move from individual technology demonstrations toward sustained constellation construction.
At 2:26 p.m. on September 15, the Zhuque-2E Y7 launch vehicle lifted off from the Dongfeng Commercial Space Innovation Pilot Zone, successfully placing 10 satellites from Qianfan Polar Orbit Group 19 into their designated orbits and completing the flight test mission.
Zhuque-2E is one of LandSpace’s primary operational launch vehicles and currently handles the company’s regular commercial missions. Its continued use gives satellite customers access to an established launch platform while LandSpace develops the larger, reusable Zhuque-3 for missions requiring greater payload capacity and a higher launch cadence.
The two rockets are designed to meet different customer and mission requirements rather than follow a simple replacement sequence. Zhuque-2E addresses current commercial demand, including near-term satellite and constellation launches, while Zhuque-3 is intended to support future missions requiring increased lift capacity and reusable launch operations.
LandSpace is also using technical commonality between the two vehicles to support faster development. Zhuque-2E and the first and second stages of Zhuque-3 use Tianque-12A and Tianque-15A engines, respectively, while both launch systems employ pneumatic pushers for separation between their first and second stages.
Sharing propulsion and stage-separation technologies can reduce development and production costs and allow qualification results, flight data and operational experience from one vehicle to inform improvements to the other. Each successful Zhuque-2E mission therefore supports immediate commercial launch demand while also generating experience relevant to LandSpace’s broader launch vehicle program.
The September 15 mission highlights the growing connection between China’s satellite manufacturing capacity, constellation deployment plans and commercial launch services. By operating Zhuque-2E alongside the developing Zhuque-3, LandSpace aims to serve current payload requirements while preparing for larger and more frequent missions as constellation demand increases.
China’s expanding commercial space ecosystem is also bringing additional satellite capacity and more competitive supply options to the international market. Global customers can contact STARPATH GLOBAL to explore cost-effective satellite imagery, payload and assembly, integration and testing services from China, matching technical requirements and budgets with suitable solutions.
