Establishing a robust and interoperable lunar communication network is essential for supporting future lunar exploration efforts, including sustained human and robotic missions. This seminar explores ongoing work focused on integrating Delay and Disruption Tolerant Networking (DTN) into lunar communication architectures to address the unique challenges of space-based connectivity. Leveraging terrestrial 3GPP (3rd Generation Partnership Project) technologies, the project demonstrates how a scalable and standardized mobile communication framework can be extended to support lunar operations. By combining DTN with 3GPP-compliant architectures, this approach aims to enable more resilient, interoperable, and adaptable communication networks aligned with the LunaNet architecture. The seminar will feature a demonstration of the current capabilities of the SPATIAM DTN Network Function for a lunar network that integrates with 3GPP systems for delivering network and user services on the Moon, including Media streaming of high-definition (HD) and ultra high-definition (4K) content and Bidirectional file transfer and messaging between emulated lunar nodes, Bidirectional telemetry, tracking, and command (TT&C) in addition to other capabilities. This demonstration illustrates the potential of SPATIAM's DTN Network Function as a foundational technology for future lunar communication systems, supporting the development of reliable, scalable, and standards-based networks for upcoming lunar missions.
