Satellites and Spacecraft

What do satellites and spacecraft need to operate?

Once a satellite or spacecraft is launched, it still needs a propulsion system to move or turn; communications and telemetry systems to send and receive data and commands from scientists and flight controllers; and an electrical energy system to power everything on the craft. For every spacecraft, the way these systems are designed and operated differs depending on the payload of the craft.
