South Korea’s Manned Space Launch Strategy through Soyuz and Falcon 9 Development Strategy

In this study, the development process of Soyuz and Falcon 9 was studied for the development of a Korean manned space launch vehicle, and it was found that only gas generator cycle engines can be used for manned launch vehicles.The minimum launch success rate required to transition to a manned space launcher was analyzed to be 95%, which would require about 40 launches for the Nuri.The basic variant of the Nuri is expected to be capable of configuring a one-or two-seat manned space launch vehicle, and when improved, it can be upgraded to the Soyuz class.
