An Internet for the Solar System (emf2026)

This talk explores the emerging concept of “An Internet for the Solar System” — a networked approach to interplanetary communication that could transform how spacecraft, habitats, and missions share data beyond Earth. Starting with NASA’s LunaNet initiative, we will examine how principles from terrestrial internet infrastructure are being adapted for the unique challenges of space: extreme latency, intermittent connectivity, and vast distances. The session will introduce Delay/Disruption Tolerant Networking (DTN), a key protocol framework enabling reliable communication where traditional internet models fail. We will explore how LunaNet envisions a federated system of lunar orbiters, surface relays, and Earth-based nodes working together as a scalable, interoperable network. A particular focus will be placed on ground infrastructure, including the role of commercial and community-accessible deep space facilities such as Goonhilly Earth Station. Once a cornerstone of satellite communications, Goonhilly is now re-emerging as a key player in deep space data links, supporting missions and opening opportunities for non-governmental participation in space communications. The talk will also consider future extensions of this interplanetary internet: Mars networks, autonomous routing between spacecraft, and the potential for open standards that enable wider access beyond national space agencies.
