Revolutionizing Lunar Communications
Nokia’s partnership with NASA marks a pivotal advancement in space communications, with an ambitious goal to establish the first-ever LTE/4G network on the Moon. As part of NASA’s Tipping Point program, this project is set to transform lunar exploration by offering robust and reliable communication capabilities vital for future missions.
Nokia Bell Labs developed the lunar network, which features an LTE Base Station with integrated Evolved Packet Core functionalities, LTE User Equipment, RF antennas, and high-reliability operations and maintenance (O&M) software. This system will be installed on the lunar lander and rovers, facilitating crucial communications across the Moon’s surface.
This advanced setup will support various data transmission applications, including voice and video communications, telemetry, biometric data exchange, and the remote control of robotic and sensor payloads.
Partnership and Execution
Nokia has partnered with Intuitive Machines and Lunar Outpost for the IM-2 mission, targeting the Moon’s south pole. The Nova-C lander, equipped with Nokia’s network, will communicate with Lunar Outpost’s MAPP rover and Intuitive Machines’ Micro-Nova hopper. This setup will enable a comprehensive exploration of the lunar surface, including mapping, data collection, and potentially identifying lunar ice.
Why LTE/4G?
LTE/4G technology was chosen for its maturity, reliability, and performance in terrestrial networks. It meets the initial mission requirements and provides a pathway to future upgrades, including 5G. This technology will ensure astronauts have access to the same advanced communication capabilities in space as on Earth, which is crucial for supporting mission operations and daily activities.
Mission Objectives and Challenges
The mission began in 2022 and aims to test and validate the network’s performance in the Moon’s harsh environment, characterized by extreme temperatures, vacuum, and radiation. The system’s compact design addresses the stringent size, weight, and power constraints typical of space payloads. The mission will also explore radio propagation on the lunar surface, providing valuable data for future missions.
Nokia aims to prove that cellular technologies can provide reliable, high-capacity, and efficient connectivity for future crewed and uncrewed missions to the Moon and other planets. Astronauts will need the same advanced capabilities in space we have on Earth to support their missions and live their lives. They will need access to voice, video, and data communications capabilities as well as telemetry and biometric data. To perform their mission tasks, they must tap into vast sensor grids, deploy scientific payloads and experiments, and remotely operate robots and other machinery. All these scenarios and applications will require robust network connectivity.
It’s possible that the first images of ice on the Moon could be sent over the Nokia lunar network. The trove of data collected on IM-2 will provide a wealth of knowledge about a key area of the Moon, helping pave the way for future crewed Artemis missions. The Moon’s surface is one of the most inhospitable environments we have ever encountered, with no atmosphere, no natural protection from cosmic radiation, and temperatures that can fluctuate by as much as 300° C between lunar day and night. If Nokia can build a network that can function on the Moon, it can build a network that can function in the most extreme environments on Earth.
Technological Components and Deployment
The lunar 4G/LTE system will have two primary components. The first is the base station unit, which will be integrated directly into Intuitive Machines’ spacecraft, the Nova-C lander, and act as the cell site for the Moon network. The second component will be the radio equipment installed on two lunar vehicles: Lunar Outpost’s Mobile Autonomous Prospecting Platform (MAPP) rover and Intuitive Machines’ Micro-Nova hopper. Together, these radio components will form a network that will allow the vehicles and landers to communicate with one another. A powerful direct-to-Earth radio connection from the lander will provide a link home, over which mission controllers will receive data and images and remotely operate the vehicles over the cellular network.
Thierry Klein, President of Bell Labs Solutions Research at Nokia, said: “Like shelter, food, and life support, communications will be a crucial component of any future lunar or Mars mission. Instead of ‘reinventing the wheel’ by creating a proprietary network in space, we are taking advantage of the same state-of-the-art technologies that connect billions of smartphones on Earth.”
Klein continued: “Humanity has always been fascinated by space, and that interest has only intensified in the 21st century. We are sending more humans and more machines into space to explore, study and even pursue new business ventures. Wherever these humans and machines go in the solar system, they will need communications. Nokia is prepared to make that journey with them.”
Future Implications
This project is a stepping stone towards a sustainable human presence on the Moon and future Mars missions. By leveraging terrestrial cellular technologies, Nokia aims to provide reliable, high-capacity connectivity for space missions, ensuring seamless communication and data transmission. The knowledge gained from this mission will enhance lunar exploration and contribute to advancements in networks deployed in extreme environments on Earth.
Nokia’s involvement in this mission is part of a broader effort to develop commercial space capabilities and support NASA’s Artemis program, which seeks to establish sustainable operations on the Moon. This initiative underscores the importance of reliable communications in space exploration and sets the stage for future innovations in space technology.
