A New Era in Lunar Communication: Axiom Space and Nokia’s Groundbreaking Partnership

The race to establish a sustainable human presence on the moon has led to some of the most innovative partnerships in space exploration history. Among these, the collaboration between Axiom Space and Nokia stands out as a significant leap forward. Announced on August 21, 2024, this partnership aims to integrate cutting-edge 4G/LTE wireless communication technologies into the spacesuits that Axiom Space is developing for NASA’s Artemis program.

At the heart of the Axiom-Nokia collaboration is the Lunar Surface Communications System (LSCS), a sophisticated communication network designed to support the Artemis spacesuits. The LSCS system will consist of two main components:

Network in a Box: This includes a base station, antennas, and other supporting systems installed on the Human Landing Services lander.
User Module: Integrated within Axiom’s spacesuits, this module will enable astronauts to connect to the LSCS seamlessly.

The system aims to provide redundancy for existing communication channels, such as UHF and Wi-Fi, while significantly increasing bandwidth. This enhancement allows for high-definition video streaming, real-time data transmission, and improved communication between astronauts and mission control.

The Artemis program, a critical part of NASA’s long-term lunar exploration goals, seeks to return humans to the moon by 2026. Axiom Space’s involvement in developing the next-generation extravehicular activity (EVA) suits is crucial to this mission. The addition of Nokia’s 4G/LTE technology will elevate the capabilities of these suits, allowing astronauts to perform more complex tasks with higher efficiency.

Russell Ralston, Axiom Space’s executive vice president of extravehicular activity, highlighted the importance of this technology in a recent interview. “From a suit perspective, we like this because it will give us a lot more capability and it gives us a little bit more redundancy in the communications,” he said. The LSCS technology offers a unique blend of reliability and versatility, providing astronauts with multiple communication options based on mission requirements.

One of the most significant benefits of the LSCS technology is its potential to revolutionize scientific operations on the lunar surface. The system enables scientists and geologists supporting the mission from Earth to gain a clearer, real-time understanding of the crew’s observations. By streaming high-definition video directly from the suit’s cameras, mission control and research teams can collaborate more effectively, making informed decisions with minimal delay.

“From a scientific perspective, what it means is all of the scientists and geologists supporting the NASA mission in real-time will have much better insight into what the crew is seeing,” Ralston explained. “People will connect with the mission a lot more closely when they can see it in such rich detail.”
