This document discusses the concept of an Interplanetary Network (IPN) which would provide internet-like connectivity throughout the solar system. The IPN would face significant challenges due to extreme propagation delays, asymmetric link capacities, high error rates, and intermittent connectivity between planets and satellites. The proposed architecture includes an Interplanetary Backbone Network connecting planets and satellites, and Interplanetary External Networks connecting spacecraft. Key applications of the IPN would be time-insensitive and time-sensitive scientific data delivery, mission telemetry, and command/control of robotic vehicles across planets. The IPN is envisioned to support increasing space exploration and future missions involving distributed landers, rovers, and even human outposts communicating with orbiters.

- 2. Introduction Objectives Challenges Architecture of IPN Working of Terrestrial Internet Working of IPN Terrestrial v/s Celestial Communication Applications Conclusion
- 3. IPN is a conceived computer network in space, consisting of a set of network nodes which can communicate with each other. IPN is a technical name for ”anywhere and everywhere internet”. It aims to provide Internet-like services over the entire solar system.
- 5. Extremely long propagation delay Asymmetrical forward and reverse Link capacities High link error rates for radio-frequency (RF) communication channels Intermittent link connectivity Lack of fixed communication infrastructure
- 6. Effects of planetary distances on the signal strength and the protocol design Power, mass, size, and cost constraints for communication hardware and protocol design
- 11. InterPlanetary Backbone Network Communication among Earth, outer-space planets, moons, satellites, relay stations, etc. InterPlanetary External Network Space crafts flying in groups in deep space between planets, clusters of sensor nodes, and groups of space stations.
- 12. Planetary Network Planetary Satellite Network Satellites circling the planets provides relay services, communication & navigation services to surface elements. Includes links between orbiting satellites & links between satellite and surface elements. Planetary Surface Network Links between high power surface elements (rovers, landers, etc). Surface elements that cannot directly talk to satellites, organized in an ad hoc manner.

- 17. “Non-chatty” message-oriented communications Essential in long delay environments. Store-and-forward between nodes Essential when no contemporaneous end-to-end path exists. Highly desirable to free resources at less-advantaged “leaf nodes”. Routing algorithms cognizant of scheduled connectivity Essential to accommodate scheduled connectivity. Highly desirable to be able to adaptively exploit alternate routes.
- 18. Use transport and network technologies appropriate to the environment Essential to support combination of IP and non-IP networks. Essential to be able to support incremental deployment of new technologies.
- 19. Time-Insensitive Scientific Data Delivery: -Large volume of scientific data to be collected from planets and moons. Time-Sensitive Scientific Data Delivery: -Audio and visual information about the local environment to Earth, in-situ controlling robots, or eventually in-situ astronauts. Mission Status Telemetry: - Delivery of the status and the health report of the mission, spacecraft, or the landed vehicles to the mission center or other nodes. Command and Control: -Closed-loop command and control of the in-situ mission elements.
- 20. With the increasing pace of space exploration, Earth will distribute large numbers of robotic vehicles, landers, and possibly even humans, to asteroids and other planets in the coming decades. Possible future missions include lander/rover/orbiter sets, sample return missions, aircraft communicating with orbiters, and outposts of humans or computers remotely operating rovers.
