* Communication systems: These systems allow the probe to send data back to Earth and receive instructions from ground control.
* Propulsion systems: These systems provide the probe with the ability to move through space and maneuver.
* Power systems: These systems provide the probe with the electrical power it needs to operate.
* Sensors and instruments: These devices collect data about the space environment, such as temperature, pressure, radiation levels, and magnetic fields.
* Cameras: These devices take pictures of the space environment and the objects it encounters.
* Sample collection systems: These systems collect samples of material from the space environment, such as rocks, soil, and gases.
* Data storage systems: These systems store the data collected by the probe's sensors and instruments.
* Guidance and control systems: These systems keep the probe on course and ensure that it functions properly.
Space probes also typically carry redundant systems to ensure that they remain functional in the event of a failure.
