Chinese launch vehicle makers are developing a fully reusable version of the super-heavy rocket
The giant rocket will consist of three stages and four side boosters, with the first stage and boosters using a fuel mixture of kerosene and liquid oxygen.
The first stage of the launch vehicle with a diameter of 10.6 meters will be able to launch 150 tons of payload into low Earth orbit, 65 tons into geosynchronous orbit or 50 tons into lunar orbit.
Long, a senior official who often provides updates on China's space activities, said new launch vehicles should be ready by 2035.
China is also developing a three-stage heavya rocket capable of sending Chinese astronauts to the moon. A two-stage low Earth orbit version could make its first flight in 2026.
