Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
In the aerospace context, chemistry refers to the study of chemical reactions and materials that are used in aerospace technology. This can include the development and testing of new propellants, fuels, and materials for use in spacecraft, aircraft, and other aerospace systems.
Examples of applications of chemistry in aerospace include:
-
Propellant chemistry, which involves the development and testing of new propellants and fuels for use in rocket engines and other propulsion systems.
-
Materials chemistry, which involves the development and testing of new materials for use in spacecraft, aircraft, and other aerospace systems. This can include the development of heat-resistant materials for use in re-entry vehicles, lightweight materials for use in aircraft, and corrosion-resistant materials for use in satellites.
-
Environmental chemistry, which involves the study of the effects of aerospace activities on the environment, such as the impact of rocket launches on air and water quality.
-
Analytical chemistry, which involves the use of analytical techniques to study the composition and properties of materials and fuels used in aerospace technology.
-
Fuel cell chemistry, which involves the development and testing of fuel cells for use in spacecraft and other aerospace applications.
Some examples of organizations that conduct research in aerospace chemistry include NASA, the European Space Agency (ESA), and the National Aeronautics and Space Administration of Russia (Roscosmos), as well as universities and private companies with research and development programs in aerospace technology.
