LunaNet – Lunar Communications and the Emerging Network on the Moon

In March 2025, the Moon briefly had a 4G network that worked for about 25 minutes. That sounds less impressive until you consider the service area: roughly 384,000 kilometers from Earth, attached to a lunar lander with no repair crew, electrical grid, or easy recovery from an awkward landing.

Nokia’s Lunar Surface Communications System traveled aboard Intuitive Machines’ Athena lander to connect nearby lunar vehicles using the same basic 4G/LTE technology used on Earth. The network powered on, its radio and core systems operated, and it transmitted data toward Earth. Athena’s landing left its solar panels unable to support prolonged operations, however, so the rover connection that would have produced the first lunar cellular “call” never happened. Nokia later confirmed that the system remained on air throughout its available power window even though the intended connection to the hopper could not be completed.

As technological demonstrations go, it was both a success and a very lunar kind of failure.

More importantly, it showed what lunar connectivity is becoming. Information may move from nearby machines to an orbital relay and then across nearly 400,000 kilometers to Earth, linking local networking with long-distance communications. The Moon is not simply getting Wi-Fi. It is beginning to acquire the standards, services, infrastructure, and economic relationships that make a connected environment possible.

The Moon’s First Telecom Problem Is the Moon

For decades, lunar communication was mostly mission-specific. A spacecraft carried its own equipment and communicated with Earth through dedicated radio links. That model becomes inefficient if the Moon begins hosting hundreds of robotic missions alongside eventual human crews.

The European Space Agency says more than 400 government and private lunar missions are planned over the next two decades. Not all will launch, but the planning volume helps explain why shared infrastructure matters. If every machine requires its own complete communications arrangement with Earth, lunar exploration starts to resemble a town where every house must build its own telephone company.

Shared networks could reduce both spacecraft burden and operating cost. Instead of reproducing an entire communications or navigation system for each mission, users could rely on infrastructure already in place.

The Moon itself creates the clearest technical case. A rover on the far side cannot point an antenna toward Earth because lunar rock blocks the signal. China’s original Queqiao relay supported Chang’e-4’s 2019 far-side landing, while Queqiao-2 later supported Chang’e-6, which returned the first samples from the Moon’s far side. Relay infrastructure did more than improve reception. It determined where a mission could operate while remaining connected.

GPS Has Already Reached the Moon

On March 3, 2025, NASA and the Italian Space Agency’s Lunar GNSS Receiver Experiment became the first system to acquire and track GPS and Galileo signals from the lunar surface. It also produced a navigation fix roughly 225,000 miles from Earth.

GPS was not designed for Moon users, so the demonstration showed that sensitive equipment can exploit terrestrial navigation signals far beyond their normal service region. Dedicated lunar systems would still provide more reliable coverage, particularly near the south pole, where terrain complicates both communications and navigation.

ESA’s Moonlight program takes the next step. Its planned architecture uses five lunar satellites and three Earth ground stations, with surface positioning targeted at accuracy of up to about three meters. Initial operations are planned by the end of 2028, followed by broader service around 2030. Navigation can therefore become something missions consume as a shared service rather than a complete capability each spacecraft must reproduce.

NASA Is Working on the Moon’s Internet Rulebook

NASA’s LunaNet project addresses a different problem: interoperability. It is not one giant NASA-owned lunar network but a framework intended to help independently operated communications and navigation systems work together.

That becomes important when equipment built by one organization depends on services operated by another. Without common interfaces, every mission inherits another integration problem.

LunaNet Version 5, released in February 2025 and developed by NASA, ESA, and JAXA, covers communications and positioning, navigation, and timing services. The internet analogy works because independently operated systems become more useful when they can exchange information through common rules.

The architecture is also moving into hardware. In July 2026, NASA delivered the 3.5-pound NavCube3-mini receiver to Intuitive Machines for integration into Altus-1, its first planned lunar relay satellite. Roughly half a shoebox in size and drawing less than 20 watts, the receiver shows how lunar navigation capability is becoming compact enough for shared commercial infrastructure.

Somebody Has to Pay the Internet Bill

Once communications becomes infrastructure, economics follows. In 2024, NASA selected Intuitive Machines for commercial lunar relay services under its Near Space Network through a contract vehicle with a maximum potential value of $4.82 billion over as much as ten years.

The $4.82 billion figure is a ceiling, not committed spending. Intuitive Machines reported $150 million in initial funded task orders, a much smaller figure that better reflects the market today: real, but still embryonic.

NASA is effectively testing a shift from mission-owned communications equipment toward purchased services. A future operator could buy relay or navigation capacity instead of building the supporting network itself. Intuitive Machines has described its planned Lunar Data Network as a scalable, pay-by-the-minute service, making the commercial model sound less like exotic space hardware and more like telecommunications.

A future Moon business may have to survive an unforgiving environment while also facing a problem recognizable to every company on Earth: its communications bill. Providers still need customers before infrastructure becomes profitable, while missions benefit from networks being available before they arrive. Governments are therefore acting as anchor customers while companies test whether shared lunar communications can support a durable service market.

Lunar Spectrum and Timing Constraints

Even the Moon Needs Spectrum Rules and a Clock

More transmitters create another familiar scarcity: spectrum. In March 2025, the International Telecommunication Union published a detailed report covering communications across the lunar surface and surrounding space.

The far side makes the tradeoff unusually sharp because the Moon shields it from much of Earth’s radio noise. FarView, a proposed low-frequency observatory, envisions roughly 100,000 dipole antennas across about 200 square kilometers. A communications system could therefore create value for one lunar activity while degrading a scientific environment that is difficult to reproduce elsewhere.

Lunar infrastructure also needs a shared clock. Because gravity and motion differ from conditions on Earth, clocks on the Moon do not tick at precisely the same apparent rate. NIST-linked research puts the difference at about 56 microseconds per Earth day. That is imperceptible to a person but important to navigation systems and networks that depend on precise timing.

Spectrum coordination and synchronized time mark a shift beyond isolated hardware. Shared infrastructure needs common rules for access and a common reference for machines expected to operate together.

Lunar Network Performance Limits

Space Internet Has One Very Annoying Ping Time

There is one constraint engineers cannot negotiate away: the speed of light. At an average Earth-Moon distance of about 384,400 kilometers, a signal takes roughly 1.3 seconds to travel one way, creating a minimum round trip of about 2.6 seconds before processing or routing delays.

Bandwidth can improve even when latency cannot. During Artemis II in 2026, NASA’s Orion optical communications system exchanged 484 gigabytes of data with Earth and reached downlink rates of up to 260 megabits per second. NASA compared that volume with roughly 100 high-definition movies. Optical links can carry much richer mission data, but a laser still travels at light speed.

Connections can also disappear when terrain blocks a signal or relay geometry changes. Delay/Disruption Tolerant Networking addresses that problem by allowing information to wait at one network node until the next usable connection appears. The standardized Bundle Protocol formalizes this store-carry-forward approach, making intermittent connectivity an expected operating condition rather than a failure.

None of this means the Moon has anything comparable to the consumer internet. Nokia’s cellular demonstration lasted minutes, Moonlight remains under development, and commercial relay services are still emerging. Yet operational relays already support far-side missions, Earth navigation signals have produced a lunar fix, and optical communications have worked at lunar distance. Standards and commercial services are now being built around those demonstrated capabilities.

The first customers will be scientific missions, machines, and astronauts rather than people streaming movies. Coverage will be patchy and expensive, but the underlying shift is clear: the Moon is acquiring a communications layer that connects organizations and equipment that would otherwise operate alone.

And if that works, Mars is next.
