Oxidizer
An oxidizer is a chemical that provides oxygen for a fuel to burn, similar to how air helps a fire burn. In rockets, it's stored separately from the fuel and mixed in the engine.
TECHNICAL DEFINITION
An oxidizer is a chemical compound that supplies oxygen or other electron-accepting species to a fuel during combustion, enabling the release of chemical energy in rocket engines, typically stored separately from the fuel.
BACKGROUND
The RS-25, also known as the Space Shuttle Main Engine (SSME), is a liquid-fuel cryogenic rocket engine that was used on NASA's Space Shuttle and is used on the Space Launch System.
