Air Composition
Air composition refers to the mixture of gases that make up the Earth's atmosphere. The most abundant gases in the atmosphere are nitrogen (78%) and oxygen (21%), with trace amounts of other gases such as argon, carbon dioxide, neon, helium, and methane. The composition of air can vary depending on location, altitude, and time of day. In space and astronautical engineering, understanding air composition is important for designing life support systems for spacecraft and spacesuits. The composition of air in spacecraft must be carefully controlled to ensure the health and safety of astronauts. Additionally, knowledge of air composition is important for designing propulsion systems for spacecraft, as the composition of the atmosphere can affect the performance of engines.
