China’s First Reusable Rocket Lands Successfully

China’s successful recovery of Landspace’s Zhuque-3 Y2 first stage marks an engineering breakthrough, but its heavier design leaves the economics and payload capacity behind SpaceX’s Falcon 9.

• On 18 August, Zhuque-3 Y2 launched the Honghu 03 satellite from Jiuquan and landed its first stage vertically about 390 km downrange in Gansu.
• Landspace became only the third group, after SpaceX and Blue Origin, to land an orbital booster on its own legs.
• The basic Zhuque-3 model has a recoverable capacity of about 8 tonnes, versus 10 to 13 tonnes for a Falcon 9 returning to its launch complex; Falcon 9 can also land on a droneship up to 680 km downrange.
• Zhuque-3 uses stainless steel that is three times as heavy as the aluminium alloy and carbon-fibre composite used by Falcon 9, trading greater re-entry resilience for lower payload capacity.
• China’s 2023 Thousand Sails plan targets 15,000 satellites in orbit by 2030, while the expendable Long March 2D has already carried 41 satellites on one launch.

Takeaway: Reliable reusable rockets could eventually help China challenge US dominance in low Earth orbit, but Zhuque-3’s payload disadvantage is likely to persist for years and the economics remain uncertain.
