The first stage uses four 75 ton liquid oxygen kerosene engines, the second stage uses a 75 ton engine, and the third stage uses a 7 ton engine, The original goal was to send a 2.6-ton load into a 300 km high low earth orbit and a 1.5-ton load into a 700 km high solar synchronous orbit

Korea Aerospace Research Institute is currently planning the second orbital flight of the “world” rocket, and the mission time is no earlier than May 19, 2022. In the future, the “world” rocket will be used to launch earth observation satellites and spacecraft related to South Korea’s lunar exploration mission
