Space Shuttle Main Engine

The Space Shuttle Main Engine (SSME) is a highly advanced, reusable rocket engine that powers the shuttle during launch. It operates by burning liquid hydrogen and liquid oxygen to produce a powerful, controlled thrust. The engine is designed for efficiency and precise control, enabling it to be restarted multiple times if needed. It is mounted on the shuttle’s orbiter and provides the primary propulsion during ascent into space. The SSME’s reliability and performance are crucial for safe crew transportation, enabling the shuttle to launch, reach orbit, and return safely to Earth.
