Substance
In space and astronautical engineering, substance refers to any material or matter that is present in the space environment. This includes gases, liquids, solids, and plasma. Understanding the behavior and properties of substances in space is crucial for designing and operating spacecraft and space systems. For example, the behavior of propellants and coolants in microgravity environments can be very different from their behavior on Earth, which can affect the performance and reliability of space systems. Additionally, the interaction between substances and the space environment, such as radiation and temperature extremes, can also impact the performance and longevity of space systems.
