OneSpace[1] (Chinese: 零壹空间[2]; pinyin: Líng Yī Kōngjiān; literally: "Zero One Space") or One Space Technology Group[3] (Chinese: 零壹空间科技[4]; pinyin: Líng Yī Kōngjiān Kējì; literally: "Zero One Space Technology") is a Chinese private space launch group based in Beijing,subsidiaries in Chongqing, Shenzhen[5] and Xi'an[6]. OneSpace was founded in 2015. OneSpace is led by CEO Shu Chang, and is targeting the small launcher market for microsatellites and nanosatellites.[7][8] OneSpace launched China's first private rocket in 2018.[9]

The company plans to unveil its family of rockets early in 2019.[10]


OneSpace's headquarters and an R&D center is located in Beijing.[10] Its research and development center, and manufacturing and assembly base, is located in Chongqing.[8][10] Its rocket engine testing facility is located in Jiangxi Province and Shanxi Province[11].[8]


OS-X series[edit]

The OS-X series of rockets are suborbital sounding rockets, reaching high altitude or reaching space but not orbit; they are meant for research and development of their launch systems.


The OS-X0 (aka "Chongqing Liangjiang Star")[12] is a 9 m (30 ft) long suborbital high-altitude rocket. It uses solid propellant and is designed to carry payloads up to 100 km (62 mi) reaching space. First flight (suborbital) was on 17 May 2018, reaching an altitude of 40 km (25 mi).[9][13][14] The rocket is built completely from homegrown Chinese technology.[9] Its launch represents the first rocket designed by a private company launched in China.[12]


The OS-X1(aka"Chongqing Liangjiang Star") is a suborbital high-altitude rocket, a sounding rocket, designed for research and testing.[8] The solid rocket motor was successfully tested in December 2017.[15] This 9-meter long rocket was launch at Jiuquan Satellite Launch Center on 20180907 (04:10 UTC), reaching an altitude of 35 km and traveling 169 km.[16]

OS-M series[edit]

The OS-M series of rockets are larger than the OS series and aim to provide low cost flights to LEO and SSO.[17] [18]


The OS-M is a light-launch spacelaunch launch vehicle rocketing payloads to low Earth orbit (LEO) and Sun synchronous orbit (SSO). It is projected to be capable of lofting 205 kg (452 lb) to 300 km (190 mi) high LEO; and 73 kg (161 lb) to 800 km (500 mi) high SSO.[8][17][19] The first launch is scheduled for Q1 2019.

As of December 2019, the tests completed for OS-M were:

  • 2018/July/4: First-stage main rocket motor test
  • 2018/August/24: Three-stage solid-state propellant and the second and third stage separation system test
  • 2018/October/23: Fourth-stage engine and the third and fourth stage separation system test
  • 2018/November/26 through Nov/30: Attitude control system mechanical environment test.
  • 2018 December: Completed the OS-M attitude control system hot fire test.[20]


The OS-M2 is similar to the OS-M1, but has two boosters. Block A will be capable of lifting 390 kg (860 lb) to LEO and 204 kg (450 lb) to 800 km (500 mi) SSO, while block B will be capable of lifting 505 kg (1,113 lb) to LEO and 274 kg (604 lb) to 800 km (500 mi) SEO.[21]


The OS-M4 has four boosters. Block A will be capable of lifting 552 kg to LEO and 307 kg to 800km SSO, while block B will be capable of lifting 748 kg to LEO and 446 kg to 800km SEO.[22]

Future OS-M rockets[edit]

The firm is anticipating making future entries in the OS-M series of rockets in some way reusable.[8]

OneSpace is developing a 59 ton rocket,[7] that was originally scheduled for launch in 2018. It is to have a 500 kg (1,100 lb) payload to LEO. This is projected to cost RMB ¥100,000 CNY/kg ($6500 USD/lb)[23] OneSpace also envisions to eventually develop a crewed space capsule.[23]


OneSpace is in competition with several other Chinese solid rocket startups, being LandSpace, LinkSpace, ExPace.[24]


On August 12th, One Space secures 300 million RMB in series B funding. Till now, One Space has completed 4 rounds of financing, which sum to 800 million RMB.
