With Artemis, NASA will establish a long-term presence at the Moon, opening more of the lunar surface to exploration than ever before. This growth of lunar activity will require new, more robust communications, navigation, and networking capabilities. NASA's Space Communications and Navigation (SCaN) program has developed the LunaNet architecture to meet these needs.

LunaNet will leverage innovative networking techniques, standards, and an extensible framework to rapidly expand network capabilities at the Moon. This framework will allow industry, academia, and international partners to build and operate LunaNet nodes alongside NASA. These nodes will offer missions four distinct services: networking, navigation, detection and information, and radio/optical science services.

Networking

Typically, when missions launch into space, their communication down to Earth is reliant on pre-scheduled links with either a space relay or a ground-based antenna. With multiple missions journeying to the Moon, the reliance on pre-scheduled links could limit communications opportunities and efficiencies. LunaNet offers a network approach similar to the internet on Earth, where users maintain connections with the larger network and do not need to schedule data transference in advance.
