Shuang Quxian-1S (Hyperbola-1S) is a small solid fuel rocket designed by the Chinese company Beijing Interstellar Glory Space Technology Ltd. under the brand name iSpace as a demonstrator for their planned Hyperbola-1 rocket.
On 4 April 2018, the 8.4 m long and 4.6 ton single stage Shuang Quxian-1S (Hyperbola-1S) test vehicle was launched from Hainan to an altitude of 108 km. On 5 September 2018 a similar Shuang Quxian-1Z (Hyperbola-1Z) was launched, which featured grid fins instad of the normal fins.
iSpace plans to perform an orbital launch of the Shuang Quxian-1 (SQX-1, Hyperbola-1) by June 2019, which might possibly use a larger stage 1 with the Hyperbola-1S as stage 2.
