Islamabad, Feb 19: Later this month, Intuitive Machines is set to launch its IM-2 mission from NASA’s Kennedy Space Center. This mission will deploy a lander, rover, and hopper near the Moon’s south pole. A key highlight of the mission is the introduction of the first 4G cellular network on the Moon, developed by Nokia Bell Labs under a NASA contract.
Why the Moon Needs 4G Connectivity
Traditionally, lunar communication has relied on point-to-point radio signals, which require a direct line of sight. These methods are outdated and inefficient for future lunar exploration. Thierry Klein, president of Nokia Bell Labs Solutions Research, emphasizes that current systems lack speed, range, and the ability to support multiple connections. As NASA plans to establish a permanent lunar base under the Artemis program, a robust 4G network will be essential for high-speed data transfer and seamless astronaut operations.

How the 4G System Works
Nokia has developed a compact “network in a box” designed to endure the Moon’s extreme conditions. This small yet powerful system contains all essential networking components, except for the power source and antenna, which will be provided by the lander’s solar panels. During the IM-2 mission, the 4G network will facilitate communication between the lander, rover, and hopper.
However, due to the harsh cold of the lunar night, the system is expected to function for only a few days before shutting down.
Future Expansion and Challenges
Nokia aims to expand this 4G network, and possibly 5G, for future Artemis missions. There are even discussions about integrating the technology into astronaut spacesuits for real-time data exchange. However, concerns remain regarding signal interference. Chris De Pree, deputy spectrum manager at the National Radio Astronomy Observatory (NRAO), has warned that LTE signals could disrupt astronomical observations.
Additionally, Harvey Liszt, NRAO’s spectrum manager, pointed out that 4G is not yet officially approved for lunar operations. While Nokia has secured a temporary waiver, it must obtain a permanent frequency allocation to ensure continued use.
The IM-2 mission marks a major step toward transforming lunar communication. If successful, this initiative could pave the way for a fully functional lunar network, supporting future space exploration and human settlement on the Moon.
