/prəˈpelənt//prəˈpelənt/The term "propellant" comes from the Latin word "propendere," which means "to bend forward." In the context of rocketry, a propellant is a substance that is burned or reacted with an oxidizing agent to produce thrust, propelling a spacecraft or missile forward. This thrust occurs due to the generation of gases, which bend forward or propel the vehicle in the desired direction, as explained by the "propendere" root. The use of propellants in rockets and spacecraft dates back to the 19th century, involving chemicals such as black powder and liquid oxygen with hydrogen peroxide or alcohol. Today, modern propellant technologies such as solid, liquid, and hybrid propellants are used in various space missions, with the goal of achieving faster and more efficient space travel.
