Abstract

SpaceX is currently leading the global launch market with the successful launch and recovery of Falcon 9 v1.2 Block 5. SpaceX developed Merlin engine, a kerosene gas generator engine, and continuously upgraded the engine from Falcon 1 to Falcon Heavy to increase payload weight. SpaceX suffered a lot of failures early on, but with the help of NASA, it was possible to overcome many crises and develop vehicles. In addition, it successfully developed reusable vehicles, which drastically reduced operating costs. Subsequent launch vehicles in Korea also need to be developed with reference to SpaceX's development strategy.

SpaceX는 현재 Falcon 9 v1.2 Block 5의 성공적인 발사 및 회수로 세계 발사 시장을 주도하고 있다. SpaceX는 케로신 가스 발생기 엔진인 Merlin 엔진을 개발하였고, Falcon 1에서 Falcon Heavy까지 엔진을 지속적으로 업그레이드하여 탑재 중량을 증가시켰다. SpaceX는 초기에 많은 실패를 겪었지만 NASA의 도움으로 많은 위기를 극복하고 발사체를 개발할 수 있었다. 또한 재사용 발사체를 성공적으로 개발하여 운용비용을 크게 절감했다. 한국의 후속 발사체도 이러한 SpaceX의 개발 전략을 참고하여 개발할 필요가 있다.
