i-Space (Chinese: 星际荣耀; pinyin: xīngjì róngyào; lit.: 'Interstellar Glory'), also known as Space Honor, Beijing Interstellar Glory Space Technology Ltd., Interstellar Glory or StarCraft Glory is a Chinese private space launch company based in Beijing and founded in October 2016. As of July 2019, i-Space has successfully launched the Hyperbola-1S and Hyberbola-1Z rockets into space on a suborbital flight and reached low Earth orbit with Hyperbola-1.
The Hyperbola-1S (also called SQX-1S), and the Hyperbola-1Z (also called SQX-1Z), are single stage, solid-fueled suborbital test rockets. The Hyperbola-1S 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). The Hyperbola-1Z rocket has a diameter of 4.6 feet (about 1.4 meters), maximum design speed of 3,580 mph (1.6 km/s) and can reach altitude of 109 miles (175 kilometers).
The second flight of i-Space was a commercial sub-orbital flight launched on 5 September 2018 from the Jiuquan Satellite Launch Center in the Gobi desert, using the Hyperbola-1Z rocket. 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). It carried payloads from private Chinese satellite companies ZeroG Labs and ADA-space. The rocket delivered three CubeSat satellites one of which subsequently parachuted back to Earth.
The Hyperbola-1 (aka Shuang Quxian-1, SQX-1) (Chinese: 双曲线一号) rocket is 20.8 meters tall, 1.4 meters in diameter and weighs 31 metric tons. It consists of four all solid fuel stages, guided by liquid attitude control engines. It can launch 300 kg into low-Earth orbit (LEO). The rocket might be based on Chinese military missiles (perhaps DF-11 or DF-15). The launch price is reported around $5 million.
Its successful maiden flight was on July 25, 2019 05:00 UTC from Jiuquan. It launched from a movable supporting platform. It placed numerous payloads, among them the CAS-7B amateur radio satellite, into orbit 300 km above Earth. CAS-7B decayed from orbit 6 August. It was the first Chinese private company to achieve orbit (orbital launches of other private companies before had failed).
The Hyperbola-2 (Chinese: 双曲线二号) rocket is a two-stage, liquid-fueled, reusable rocket to lift 1.9 tons into LEO. It uses liquid oxygen and methane as fuel. The first stage is expected to land propulsively in order to be reused. The JD-1 engine made its first hot fire test in May 2020.
