Nokia Leads The Construction Of The First 4G Network On The Moon, An Essential Step For Future Lunar Colonies And Space Exploration Towards Mars
On February 26, the IM-2 mission from Intuitive Machines promises to make history. Between a rover and a hopper, the landing module is an unprecedented innovation: a fully functional 4G cellular network on the Moon.
This technology, developed by Nokia Bell Labs, has never left Earth orbit. Now, it can transform the way humanity communicates in space.
The proposal is ambitious. The lunar 4G network can pave the way for astronauts, robots, and even future colonists to maintain the same connectivity that powers billions of smartphones on Earth. It is a step that could change space exploration forever.

From Apollo To Artemis: A New Era Of Lunar Communication
For decades, lunar communications relied on point-to-point radio. During the Apollo missions, a single module or rover communicated with Earth, sending only limited data.
“They were based on technologies [ultra high frequency] or [very high frequency] connecting a small number of devices with relatively low data transfer rates,” explains Thierry Klein, president of Nokia Bell Labs Solutions Research.
Now, the scenario has changed. NASA’s Artemis program plans to return astronauts to the Moon by 2028 and establish a permanent habitat in the 2030s. With more people, devices, and data circulating, the old communication model no longer meets the needs.
The answer is the Lunar Surface Communication System (LSCS), a sort of “network in a box.” This innovative system includes a base station and an antenna mounted on the landing module.
Designed to withstand radiation, vibration, and extreme temperatures, the LSCS draws power from the solar panels of the module. It will provide high-speed communication between the landing module, a rover, and a hopper during the IM-2 mission.
“We intend to prove that cellular technologies can provide the reliable, high-capacity, and efficient connectivity needed for future crewed and uncrewed missions to the Moon and, eventually, to Mars,” emphasizes Klein.
A Network Made For The Moon — And Beyond
The IM-2 mission builds on the success of the IM-1 mission, which used the Nova-C lunar module. For this new phase, the upgraded module has been named Athena and includes significant advancements, such as a lighter helium pressure tank.
Athena has a requested destination: the “Mons Mouton” region of the Moon, located 160 km from the lunar South Pole.
This will be the closest landing ever attempted in this area. The expectation is that Athena will demonstrate lunar mobility, resource prospecting, and analysis of volatile substances beneath the surface.
In addition to proving its exploration capabilities, the IM-2 mission will also serve to test the durability and efficiency of the 4G network under extreme lunar conditions.
Nokia envisions a future where lunar habitats, rovers, and space trajectories are interconnected through 4G or 5G networks. “Perhaps just one network in a box, one tower, would provide all the coverage or maybe we would need several of them,” comments Klein.
But building this network on the Moon has not been simple. The technology needs to be adapted to the challenges of the space environment. Each of the 14 mounting points on the landing module is thermally insulated to protect the network from extreme cold.
Intuitive Machines also integrated the LSCS into the thermal protection system of the module, which regulates the temperature during operations.
A First Step Towards The Future
The lunar network allows for high-definition video transmission, command communications, and telemetry data.
The IM-2 mission represents a crucial test. Although the network will only operate for a few days, until the lunar night forces the systems to shut down, its success could lay the groundwork for a new era in space exploration. An era where connectivity on the Moon will be as seamless as it is on Earth.
Who knows, in a not-so-distant future, lunar colonists may be able to scroll through their phones under the light of Earth, just as they do under the glow of the Moon.
