Interplanetary communication is the study and development of communication systems and technologies that enable communication between different planets or celestial bodies within the solar system. This research area focuses on overcoming challenges such as long distances, signal delays, and disruptions caused by planetary orbits and atmospheres. Scientists and engineers involved in interplanetary communication work on designing reliable communication protocols, antennas, and spacecraft systems to enable the exchange of data and information between spacecraft, rovers, satellites, and ground stations on different planets. This field is crucial for space exploration missions and scientific research across the solar system.
