i-Space[1] (Chinese: 星际荣耀; pinyin; xīngjì róngyào; literally: "Interstellar Glory"), also known as Space Honor[2] or Beijing Interstellar Glory Space Technology Ltd.[3] is a Chinese private space launch company based in Beijing and founded in October 2016. As of August 2018, i-Space has successfully launched the Hyperbola-1S rocket into space twice on a suborbital flight.[2][4]



The Hyperbola-1S, also called SQX-1Z,[5] is a single stage, solid-fueled test rocket. The rocket is 8.4 meters (28 ft) long, with a diameter of 1 meter (3 ft 3 in) and weighs 4.6 tonnes (10,000 lb).

Its first sub-orbital test flight took place in April 2018.[4] Its second flight was a commercial sub-orbital flight launched on 5 September 2018 from the Jiuquan Satellite Launch Center in the Gobi desert. The sub-orbital flight reached an altitude of 108 kilometres (67 mi) and a peak velocity of over 1,200 metres per second (3,900 ft/s).[6] It carried payloads from private Chinese satellite companies ZeroG Labs and ADA-space. The rocket delivered three CubeSat satellites that subsequently parachuted back to Earth.[7]


The Hyperbola-1 rocket is under development and aims to lift 300 kg into low-Earth orbit (LEO) by June 2019.[6]


The Hyperbola-3 rocket is a two-stage, liquid-fueled, reusable rocket that aims to lift 2 tons into LEO by 2021.[6]

Other developments[edit]

In May 2018, i-Space indicated they hoped to eventually develop a reusable sub-orbital spaceplane for space tourism.[5][8][dead link]
