Xenon is a chemical element with the symbol "Xe" and atomic number 54. It is a noble gas that is used in a number of aerospace applications.
One common use of xenon in the aerospace industry is in thrusters for spacecraft. Xenon is an inert gas that can be ionized to create plasma, which can be used to generate thrust for propulsion. Xenon thrusters are often used for station-keeping and attitude control on spacecraft, as they can provide a high level of thrust with relatively low mass.
Xenon is also used in a variety of other aerospace applications, including as a fill gas for airbags and as a refrigerant in air conditioning systems.
Overall, xenon is an important element in the aerospace industry, and it has a number of applications in aerospace technology.
