At 07:35 on August 19, 2026, LandSpace's independently developed Zhuque-3 (Yao-2) launch vehicle lifted off from the Dongfeng Commercial Aerospace Innovation Test Zone. The first stage successfully landed at the designated recovery site, while the second stage delivered the Honghu-03 satellite into its intended orbit—marking China's first vertical land recovery of a rocket first stage and the first use of landing legs for recovery. This milestone transitions the Zhuque-3 from recovery technology validation to engineering-level reuse testing. Zhuque-3 is LandSpace's next-generation reusable liquid oxygen-methane rocket. Over 60% of its Tianque-series engine components are manufactured using metal 3D printing, with critical parts such as the gas generator, combustion chamber, turbopump housing, and injector printed by BLT using primarily superalloys, titanium alloys, and stainless steel. The demand for lightweight, integrated, and rapidly iterated engine designs in reusable rockets is accelerating the large-scale adoption of metal additive manufacturing in commercial aerospace. Value for powder buyers: ① As reusable rockets enter engineering validation, higher launch frequency and engine reuse rates will drive continuous procurement and batch qualification of aerospace-grade superalloy and titanium powders; ② Private rocket firms like LandSpace, following a 'low-cost + rapid iteration' approach, are increasing 3D printing usage, ensuring robust demand for superalloy, titanium alloy, and copper alloy powders (for thrust chambers); ③ Watch for derivative powder demand from hot-section component repair and remanufacturing enabled by rocket reuse.
