The Interplanetary Internet is a proposed communication network designed to connect spacecraft and missions across different planets in our solar system. It aims to overcome the challenges of long distances and delays in data transmission, which can take minutes to hours depending on the location of the planets. This network would use advanced technologies, such as delay-tolerant networking (DTN), to ensure reliable communication even when signals are weak or intermittent. By establishing a robust system, the Interplanetary Internet could support future exploration missions to places like Mars and beyond, enabling scientists to share data and collaborate more effectively.
