Chemicals


Chemicals refer to any substance with a distinct molecular composition that is produced by or used in a chemical process. In the context of space and astronautical engineering, chemicals play a crucial role in the propulsion systems of spacecraft. Chemical propulsion systems rely on the chemical reaction between a fuel and an oxidizer to produce thrust. The most common chemical propellants used in spacecraft are liquid hydrogen and liquid oxygen, which react to produce water vapor and heat. Other chemicals used in space and astronautical engineering include lubricants, coolants, and cleaning agents, which are used to maintain and operate spacecraft and their components in the harsh environment of space.
