Passive Systems

Passive systems refer to the use of natural phenomena or materials to achieve a desired function in space and astronautical engineering without the need for active control or external power. These systems rely on the inherent properties of materials or the environment to perform their intended function. Examples of passive systems include thermal control coatings that reflect or absorb heat, deployable structures that use stored energy to unfold, and aerodynamic shapes that use natural airflow to stabilize a spacecraft. Passive systems are often preferred over active systems because they are simpler, more reliable, and require less maintenance. However, they may have limitations in terms of performance and adaptability to changing conditions.
