i-Space ^[1] (other forms of writing the name are also wide spread in the media; Chinese: 星际荣耀; pinyin; xīngjì róngyào; literally: "Interstellar Glory", also known as Space Honor,^[2] Beijing Interstellar Glory Space Technology Ltd.,^[3], Interstellar Glory^[4] or StarCraft Glory^[5] 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^[2]^[6] and reached low Earth orbit with Hyperbola-1.^[7]

The company develops solid fuel small satellite orbital launchers. The main components of the company's rockets, e.g. solid propellant engines, are outsourced and produced by the CASC.^[5]

Rockets

Suborbital rockets: Hyperbola-1S and Hyberbola-1Z

The Hyperbola-1S (also called SQX-1S),^[8] and the Hyperbola-1Z (also called SQX-1Z),^[9] 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).^[8]

The first sub-orbital test flight of Hyperbola-1S took place from Hainan island^[10] in 5 April 2018^[6]^[5] to an altitude of 108 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).^[11] 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.^[12]

Hyperbola-1

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.^[13] It can launch 300 kg into low-Earth orbit (LEO).^[11] The rocket might be based on Chinese military missiles (perhaps DF-11 or DF-15).^[14]^[15] The launch price is reported around $5 million.^[16]

Its successful maiden flight was on July 25, 2019 05:00 UTC from Jiuquan.^[7]^[14] It launched from a movable supporting platform^[16]. It placed numerous payloads^[17], among them the CAS-7B^[18] amateur radio satellite, into orbit 300 km above Earth. CAS-7B decayed from orbit 6 August.^[19] It was the first Chinese private company to achieve orbit (orbital launches of other private companies before had failed).^[15]

The 1st stage is equipped with grid fins,^[20] presumably for attitude control.^{[citation needed]}

Hyperbola-2

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.^[20] The JD-1 engine made its first hot fire test in May 2020.^[21]

Other developments

In May 2018, i-Space indicated they hoped to eventually develop a reusable sub-orbital spaceplane (Chinese: 亚轨道概念飞行器) for space tourism.^[9]^[22]^{[dead link]}
