LandSpace (Chinese: 蓝箭[2]; pinyin: Lán Jiàn; lit. 'Blue Arrow') or Landspace Technology Corporation[3] (Chinese: 蓝箭空间科技[4][5]; pinyin: Lán Jiàn Kōngjiān Kējì; lit. 'Blue Arrow Space Technology') is a Chinese private space launch company based in Beijing.[6][3] It was founded in 2015 by Tsinghua University alumni Zhang Changwu.[7][6][8]

The company conducted its first launch of the Zhuque-1 launch vehicle on 27 October 2018, however the payload failed to reach orbit due to an issue with the third stage.[9][10]

The firm aims to develop, build and operate a solid-fueled orbital rocket Zhuque-1, which is technologically based on the Long March 11 rocket of the Chinese government. LandSpace also aims to develop an original rocket design, the liquid-fueled orbital rocket Zhuque-2.[11]

Launch vehicles

Zhuque-1

Zhuque-1

Zhuque-1 (ZQ-1, Chinese:朱雀一号 or 朱雀·南太湖号), also called LandSpace-1 or LS-1 (the name LandSpace-1 or LS-1 was originally reserved for a different rocket that did not in the end materialize;[12] after cancellation of the rocket, the name LandSpace-1 was affiliated to LandSpace's rocket-to-be-developed, the Zhuque-1), is a 19 m (62 ft)-tall, three-stage solid-propellant rocket. All stages have a diameter of 1.35 m. It is likely based on the DF-26 missile's rocket motor.[13] Zhuque-1 has a takeoff mass of 27 t (30 tons) and a thrust of 45 tf (99,000 lbf), and is able to carry 300 kg (660 lb) of payload into a 300 km (190 mi) low Earth orbit.[9]

The maiden flight of Zhuque-1 was on 27 October 2018 from a mobile platform at the Jiuquan Satellite Launch Center, carrying Weilai-1 satellite for China Central Television. After a successful first- and second-stage firing, and fairing separation, the payload failed to reach orbit due to an issue with the third stage.[9][10] Zhuque-1 was the first Chinese private orbital rocket to attempt an orbital launch.[14]

According to some reports, the manufacturer of the solid rocket motors has ended their contract with LandSpace. This raised doubts as to whether there will be a second flight of Zhuque-1.[13]

Zhuque-2

LandSpace is also developing a liquid-fuelled rocket called Zhuque-2 (ZQ-2).[6] Zhuque-2 is a medium-sized rocket powered by liquid oxygen and methane capable of lifting 4,000 kg of payload into a 200 km low Earth orbit, or 2,000 kg of payload into a 500 km Sun-synchronous orbit.[15][16] As of July 2018, the rocket was planned to be launched in 2020,[17] however by 2019 this had slipped to 2021.[18]

Zhuque-2 will have a liftoff weight of 216 metric tons and use 4 TQ-12 methalox engines on the first stage each with a thrust of 67 metric tonnes.[19][20] The second stage will use 1 vacuum optimised TQ-12 with a thrust of 80 metric tonnes in combination with a 10 metric tonnes thrust TQ-11 engines which will act as a vernier thruster.

In May 2019, LandSpace did test firings of its liquid methane and LOX fuelled TQ-12 rocket engine at its test facility at Huzhou, Zhejiang province. LandSpace's head of research and development, Ge Minghe, says the engine has a thrust of 80 tonnes. 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.[21][22]

Marketplace

LandSpace is one of several Chinese solid rocket startups in competition, others being OneSpace, LinkSpace, ExPace,[23] i-Space and Galactic Energy.
