Spacecraft Bus

A spacecraft bus is the core framework of a satellite or space vehicle, providing the essential support systems needed for its operation. It includes structures, power supplies, thermal management, communication systems, and attitude control. Think of it as the "body" of the spacecraft, holding all the scientific instruments and payloads in place, while ensuring they function properly in the harsh environment of space. The bus is designed to be reliable and adaptable, allowing the mission's specific instruments to perform their tasks effectively.
