Beijing-based startup iSpace successfully sent two satellites into the designated orbits with their own rocket on Thursday. It is the first company to complete such a mission in the commercial space industry at a domestic level. The SQX-1 Y1 is the 20.8-meter-tall four-stage solid-propellant carrier rocket carrying two satellites. The rocket blasted off at 1:00 p.m. BJT from a supporting pad in the large desert at the Jiuquan Satellite Launch Center, northwest China. With a liftoff weight of 31 metric tonnes and a diameter of 1.4 meters, the rocket can carry a payload of 260kg into a sun-synchronous orbit 500 km above the Earth. Established in 2015, the startup iSpace is China's first private company to get a license to develop carrier rockets.
