Link Space Aerospace Technology Inc.
FounderHu Zhenyu, Yan Chengyi, and Wu Xiaofei

LinkSpace[1] (Chinese: 翎客航天[2][3]; pinyin: Líng-kè Hángtiān; lit. 'LINK Aerospace') or Link Space Aerospace Technology Inc. is a Chinese private space launch company based in Beijing. It is led by CEO Hu Zhenyu,[4] and founded as the first private rocket firm in China.[5] The company was founded in 2014, by Hu Zhenyu, a graduate of South China University of Technology; Yan Chengyi, a graduate of Tsinghua University; and Wu Xiaofei, a manufacturing expert. The company is registered in Shenzhen.[6]


Test rockets

In 2013, before the official registration of the company, Hu's team was testing the KC-SA-TOP suborbital rocket with 50 kg (110 lb) payloads in Horqin Left Rear Banner, Inner Mongolia Autonomous Region.[5][6]

VTVL prototypes

LinkSpace has built flying vertical-takeoff/vertical-landing (VTVL) prototype test rockets, to develop its reusable rocket technology. By July 2016, it achieved hover flight with a single-engine thrust-vectored rocket. By September 2017, it had built three hovering rockets, tested in Shandong Province.[4]

On 19 April 2019, the VTVL prototype test rocket RLV-T5 flew to a height of 40 m (131 ft) and landed safely after thirty seconds of flight.[7] RLV-T5, also known as NewLine Baby, is 8.1 m (27 ft) in length, weighs 1.5 t (1,100 lbs) and has five liquid engines.[8]

On 10 August 2019 the company reported a test flight reaching a height of 300 meters.[9]

New Line 1

The New Line 1 (Xin Gan Xian 1; Chinese: 新干线一号; pinyin: xīn gàn xiàn 1) is a two-stage rocket under development to launch microsats and nanosats, with a reusable first stage. It is to be a liquid-fuelled rocket, with a diameter of 1.8 m (5.9 ft), height of 20 m (66 ft). It would have a lift-off mass of 33 t (32 long tons; 36 short tons) and take-off thrust of 400 kN (90,000 lbf), allowing a payload of 200 kg (440 lb) to be lifted into a Sun synchronous orbit (SSO) of 249–550 km (155–342 mi) high.[10]

The first stage would have four liquid engines, fueled by kerolox (liquid oxygen and kerosene), each producing 100 kN (22,000 lbf) of thrust.[11] It is projected to have an initial launch cost of $4.5 million, dropping to $2.25 million using a reused first stage.[10] As of the end of 2017, the main rocket engine has been tested over 200 times, and first launch was planned for 2020.[12]

Future New Line rockets

Future development of a reusable second stage, in addition to the reusable first stage, is anticipated for in a future vehicle, such as New Line 3.[4]


LinkSpace is planning to also be a transport and rocket services company, providing rocket parts, and transportation. As part of the transportation, it will not just send payloads into orbit, or on suborbital jaunts; it also plans to send packages from one point on Earth to another point. This is similar to SpaceX's plan for suborbital rocket passenger transport anywhere around the world with Starship.[13]


LinkSpace is in competition with several other Chinese rocket startups, being LandSpace, OneSpace, ExPace.[14] With rocket reusability and point-to-point transport, it is similar to SpaceX.[13]
