Spacecraft Subsystems

Overview of Subsystems

1. Power Subsystem - Manages electric power generation, storage, and distribution.
2. Attitude Control Subsystem - Responsible for maintaining desired orientation in space.
3. Structure & Mechanisms Subsystem - Provides physical support, including structural integrity and movable parts.
4. Command and Data Handling Subsystem - Processes commands and handles spacecraft data.
5. Communications Subsystem - Facilitates interaction with ground stations and other spacecraft.
6. Propulsion Subsystem - Allows for adjusting orbits and attitude.
7. Thermal Control Subsystem - Maintains equipment within operational temperature ranges.

Functionality of Subsystems

Each subsystem bears significant operational functions critical to the spacecraft's capabilities and mission success.
