|Products||Launch service provider|
i-Space (other forms of writing the name are also wide spread in the media; Chinese: 星际荣耀; pinyin; xīngjì róngyào; literally: "Interstellar Glory", not to be confused with the Japanese ispace), 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.
Suborbital rockets: Hyperbola-1S and Hyberbola-1Z
The Hyperbola-1S (also called SQX-1S), and the Hyperbola-1Z (also called SQX-1Z), are single stage, solid-fueled suborbital test rockets. The Hyberbola-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 Hyberbola-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 Hyberbola-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 Shian Quxian-1, SQX-1) rocket is 20.8 meters tall, 1.4 meters in diameter and weighs 31 metric tons. It consist of three solid fuel stages and a liquid fuel fourth stage. 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 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.
