Zhuque-2 Launch

Zhuque-2 (Chinese: 朱雀二号; pinyin: Zhūquè èr hào; lit. 'Zhuque-2', ZQ-2) is a Chinese medium-class orbital launch vehicle developed by LandSpace. It is a liquid-fuelled rocket powered by liquid oxygen and liquid methane (methalox) and was the first methane-fueled rocket to reach orbit.[2][3]

Design

[edit]

Zhuque-2 has a liftoff weight of 216 tonnes and uses 4 TQ-12 methalox engines in the first stage, each with a thrust of 67 tonnes-force (660 kN).[4][5] The second stage uses one vacuum-optimized TQ-12 with a thrust of 80 tonnes-force (780 kN) in combination with a TQ-11 engine (8 tonnes-force (78 kN) thrust), which acts as a vernier thruster.[6]

Zhuque-2 is capable of lifting 6,000 kg of payload into a 200 km low Earth orbit and 4,000 kg of payload into a 500 km Sun-synchronous orbit.[2][7]

History

[edit]

In May 2019, LandSpace performed test firings of its liquid-methane and liquid-oxygen fuelled TQ-12 rocket engine at its test facility at Huzhou, Zhejiang province. LandSpace's head of research and development, Ge Minghe, says that the engine has a thrust of 80 tonnes-force. The Huzhou facility will be able to produce about 15 ZQ-2 rockets and 200 TQ-12 engines starting in 2022, according to CEO, Zhang Changwu.[8][9][needs update]

On 14 December 2022, LandSpace conducted the debut flight of Zhuque-2, but failed to reach orbit due to an early shutdown of its second-stage vernier engines after the second-stage main engines apparently completed a successful burn. It was the world's first orbital launch attempt by a methane-fueled launch vehicle.[10]

In March 2023, LandSpace confirmed that the second Zhuque-2 launch vehicle had completed assembly and was undergoing preparations for a launch attempt in the coming months.[11]

On 12 July 2023, Zhuque-2 became the first methane-fueled launch vehicle to reach orbit after a successful second flight.[2][12]

An enhanced version of the rocket, the Zhuque-2E, successfully placed two satellites into orbit on 27 November 2024. The new version of the rocket differs from the initial variant by featuring a common bulkhead tank structure, a new TQ-15 liquid oxygen and methane engine with thrust vectoring capabilities on the second stage, and a new niobium alloy nozzle extension on the enhanced TQ-15A engine.[13]

ZQ-2E (Block 2)

[edit]

The Zhuque-2E (Y5), launched on 14 May 2026, is the first of the Block 2 subvariant of the launch vehicle. Various improvements were included on the Block 2 variant which allow the launch vehicle to reach its full designed capabilities such as lifting 6,000 kg (13,000 lb) to Low Earth orbit and 4,000 kg (8,800 lb) to a 500 kilometre SSO orbit. Improvements over the base ZQ-2E include: lengthened first-stage tanks, full subcooled propellant loading, a three-ignition second stage allowing orbital disposal, and an accelerated launch campaign and launch cycle. According to Spacenews.com, the 14 May 2026 "...launch successfully inserted a 2,800-kilogram customized payload described as a 'large-scale constellation deployment experiment' into a 900-kilometer polar orbit, ... The mission demonstrated high-mass payload launch capability and readiness for multi-satellite launch services, the company said in a post-launch statement, as it looks to secure launch contracts from China’s megaconstellation projects."[1]
