NASA is building a “neighborhood network” on the Moon so astronauts can stay connected
5G is the technology that keeps smartphones connected on city streets. Soon, it may do the same on the Moon.
NASA is moving forward with plans to build a wireless communications network on the lunar surface — one designed to let astronauts and robotic systems coordinate in real time, without routing every signal back to Earth. The agency has now backed that vision with a funded contract, and a live demonstration on the Moon is part of the deal.
A $38 million bet on lunar connectivity
NASA has awarded Modulate Space Corporation a firm-fixed-price contract worth approximately $38 million to develop a 5G communications system for the lunar surface, complete with integrated Wi-Fi 6. Glenn Research Center in Cleveland is the NASA hub overseeing the work.
A firm-fixed-price contract matters beyond the dollar figure. It means the agreed price doesn’t change based on what it ultimately costs the contractor to deliver. NASA knows exactly what it’s spending — no cost overruns, no renegotiations mid-mission. That kind of cost certainty is a deliberate choice for a project with a hard deadline and a very specific deliverable.
The contract covers two distinct work areas that together aim to build what NASA describes as a scalable, standards-based lunar communications capability. The goal isn’t a one-time experiment. It’s the foundation for a system designed to grow alongside future Moon Base operations.
Two phases, one ambitious goal
The contract unfolds in two sequential phases. Phase 1 — the 5G Network-in-a-Box Development and Lab Demonstration — runs from October 1, 2025 through January 31, 2028. This is the ground-based validation stage: build it, test it, prove it works in a controlled environment before anyone ships hardware to the Moon.
Phase 2 follows immediately. The Lunar 5G and Wi-Fi 6 Integrated Surface Network and Flight Demonstration runs from November 30 through December 31, 2028 — a tight window that represents the real milestone: an actual demonstration on the lunar surface.
You don’t skip straight to the Moon. Ground testing reveals failure points that are far cheaper to fix in a lab than 238,000 miles away, and by the time hardware reaches the lunar surface, it’ll have already survived rigorous terrestrial scrutiny.
The dual-standard approach — combining 5G and Wi-Fi 6 — is worth understanding clearly. These aren’t competing technologies; they serve different roles. 5G handles longer-range, higher-bandwidth links between distant assets, while Wi-Fi 6 covers shorter-range, high-density connections within a habitat or work zone. Together, they form a layered network.
Why the Moon needs its own wireless network
Right now, lunar communication runs through Earth-based relay links. Every signal travels from the Moon to Earth and back. At the Moon’s distance, that round trip introduces latency that makes real-time coordination difficult and, in emergencies, genuinely dangerous.
A local surface network changes that equation. Astronauts, rovers, and habitats could exchange data without waiting for a signal to cross space twice — and that kind of responsiveness becomes essential as surface operations grow more complex.
The Moon also presents radio propagation challenges that Earth networks never face. There’s no atmosphere to scatter or absorb signals in familiar ways. The terrain is extreme — craters, ridges, and boulder fields that create unpredictable dead zones. Lunar dust, famously abrasive and electrostatically charged, can interfere with hardware in ways still being studied. Any surface network has to account for those conditions from the very beginning.
Hardware, firmware, and the road to scalability
The contract covers development of hardware, firmware, and software as an integrated package — not separate procurement efforts stitched together after the fact. That integration matters because lunar systems can’t afford the compatibility gaps that occasionally plague terrestrial tech rollouts.
NASA‘s stated goal is to gain insight into system architecture and operational performance. That language signals something important: this isn’t just about getting a demo to work once. The agency wants to understand how it works, so informed decisions can be made about what comes next.
Building on established 5G and Wi-Fi 6 standards means the system can evolve as those standards improve, rather than becoming a proprietary dead end. In a lunar context, scalability means starting with a minimal viable network — perhaps a few nodes covering a small base area — and expanding as more missions arrive and infrastructure accumulates.
What comes after the 2028 demonstration
A successful flight demonstration in late 2028 would be a significant milestone, but it’s explicitly a step in a longer journey. NASA’s Artemis program has set sustained human presence on the Moon as a core objective, and a functioning surface communications network is a prerequisite for that ambition — not an optional add-on.
The flexibility built into the technology design allows it to be upgraded as standards evolve and mission requirements shift. That’s a practical acknowledgment that a Moon Base in the 2030s will likely look very different from anything deployable today.
Open questions remain. How many network nodes would a functional base require? What surface area can realistically be covered? Perhaps most pressing: how does the system perform during the lunar night, when temperatures plunge and power generation from solar panels drops sharply? The 2028 demonstration will start answering some of those questions — and almost certainly raise new ones.
