Respond to the following 5 questions:
1. Relating to control systems, explain in detail the difference between open-loop and closed-loop control systems?
2. Describe in detail of the various functions of control systems in spacecraft technology?
3. On space vehicles, control systems are a basic part of almost all payloads and subsystems. To support the payload, each subsystem in the spacecraft bus needs to control something as well. Explain in detail what these subsystems would be?
4. Describe in detail what is the space systems engineering process?
5. Relating to Environmental Control and Life-support Subsystem (ECLSS) explain how to use the three basic means of heat transfer—conduction, convection, and radiation—and how to use them on spacecraft technology?
