Air
In space and astronautical engineering, air refers to the mixture of gases that make up the Earth's atmosphere. The composition of air includes nitrogen, oxygen, argon, carbon dioxide, and other trace gases. Understanding the properties of air is crucial for designing spacecraft and space suits that can support human life in the vacuum of space. Engineers must consider factors such as air pressure, temperature, and composition when designing life support systems for astronauts. Additionally, air resistance plays a role in the design of spacecraft and their trajectories. The study of air and its properties is an important aspect of space and astronautical engineering.
