What features do all space probes have in common and what do theses features do?

All space probes share common features such as communication systems, power sources, and scientific instruments. Communication systems enable data transmission back to Earth, allowing scientists to receive and analyze information about the probe's findings. Power sources, often solar panels or radioisotope thermoelectric generators, provide the necessary energy for the probe's operations. Scientific instruments are tailored to gather specific data, such as images, temperature readings, or chemical compositions, contributing to our understanding of space and celestial bodies.
