Interplanetary Networks refer to communication systems designed to connect spacecraft and other devices across different planets and celestial bodies. These networks enable data exchange, allowing scientists to gather information from missions exploring planets like Mars or Venus. The concept involves using satellites and relay stations to transmit signals over vast distances in space. This is crucial for coordinating missions, sending commands, and receiving scientific data. As space exploration advances, developing robust interplanetary networks will enhance our understanding of the solar system and support future human missions to places like the Moon and Mars.
