About
Zhuque-2 is a two-stage, liquid oxygen/liquid methane (methalox) orbital launch vehicle developed by the Chinese private aerospace company LandSpace. Standing 49.5 m tall with a 3.35 m core diameter and a liftoff mass of about 219 tonnes, the rocket is powered by four TQ-12 methalox engines on its first stage and a vacuum-optimized TQ-12 engine paired with a TQ-11 vernier thruster on its second stage. Designed to serve the growing commercial small-to-medium satellite launch market, Zhuque-2 targets LEO and SSO missions at lower cost than traditional cryogenic or hypergolic rockets. Its maiden flight on 14 December 2022 reached space but failed to attain orbit after an early shutdown of the second-stage vernier engine. On 12 July 2023, the second flight successfully placed its payload into orbit, making it the first methane-fueled launch vehicle in history to reach orbit. A third successful flight followed on 8 December 2023. LandSpace has since introduced the stretched, higher-thrust Zhuque-2E variant.
