Your question is Components in a Satellite CubeSat. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about the components you can find inside a satellite CubeSat class.
Name the major physical and functional subsystems, explain the responsibility of each, and describe how they interact during a typical mission such as imaging Earth and transmitting the result to a ground station. Distinguish spacecraft platform components from the mission payload, and mention important interfaces or dependencies between subsystems.
Keep the answer at the level of a typical 1U, 2U, or 3U CubeSat. Focus on subsystem responsibilities, power and data flow, communications, attitude control, and operational concerns rather than vendor-specific hardware.
