SSME (Space Shuttle Main Engine)

The Space Shuttle Main Engine (SSME) is a powerful rocket engine used to propel the space shuttle into orbit. It runs on liquid hydrogen and liquid oxygen, which combine to produce a high-speed exhaust that generates thrust. Known for its efficiency and reusability, the SSME is designed to perform reliably through multiple flights. It operates by rapidly expanding and accelerating gases to push the shuttle upward. As a critical component, its advanced engineering allows precise control of thrust and minimizes fuel consumption, playing a key role in the shuttle's ability to launch, orbit, and return safely to Earth.
