Planetary Pros: Satellites are a versatile and efficient means of communication for space missions.
Satellites in orbit can relay signals between spacecraft and ground stations and can transmit larger volumes of data such as images and scientific measurements.
Satellite communication can provide continuous coverage even in remote or inaccessible areas of the Earth.
Cosmic Cons: Putting satellites in space is expensive and satellite communication systems require lots of maintenance which can be expensive and difficult.
The need for ground-based tracking and control stations makes it even more tricky to set up.
Satellites in orbit are susceptible to space weather effects, which can impact signal quality and availability.
