Variable
In space and astronautical engineering, a variable is a quantity or a characteristic that can change or take on different values. Variables can be classified as independent or dependent. Independent variables are those that can be manipulated or controlled, while dependent variables are those that are affected by changes in the independent variables. In space and astronautical engineering, variables can be used to describe the behavior of systems, such as spacecraft or rockets, and to predict their performance under different conditions. Examples of variables in space and astronautical engineering include thrust, velocity, altitude, temperature, pressure, and fuel consumption.
