Oxidizer
In space and astronautical engineering, an oxidizer is a substance that releases oxygen atoms to support the combustion of a fuel. It is a critical component of rocket propellants, as it provides the oxygen necessary for the fuel to burn in the absence of air. Common oxidizers used in space and astronautical engineering include liquid oxygen, nitrogen tetroxide, and hydrogen peroxide. The choice of oxidizer depends on the specific application and the desired performance of the rocket engine. However, oxidizers can be highly reactive and pose significant safety risks, requiring careful handling and storage procedures.
