The Zhuque family, who lived in the Hexi Corridor on the ancient Silk Road, established LANDSPACE and has been exploring environmental, economic, and safety propellants. Little Zhuque visited LANDSPACE and learned about various liquid propellants, including liquid oxygen and kerosene with high thrust but easy carbon accumulation, environmentally friendly liquid oxygen and liquid hydrogen with high energy consumption, stable but toxic unsymmetrical dimethylhydrazine and nitrogen tetroxide. Finally, they discovered that the Zhuque Two carrier rocket, launched by LANDSPACE, was the world’s first rocket to use liquid oxygen and methane as propellants. Liquid oxygen and methane are expected to have broader applications in the future due to their abundant reserves, easy storage conditions, safe transportation, complete combustion, and pollution-free combustion products.
