NASA has delivered the NavCube3-mini payload to Intuitive Machines for integration into Altus-1, the company’s first lunar relay satellite, marking an important milestone in the development of future lunar communications and navigation services. The lunar relays are designed to enable communications and navigation for astronauts and rovers operating at the agency’s future Moon Base. Lunar navigation is crucial for the success of these missions.
The NavCube3-mini is a compact but powerful navigation receiver designed to use signals from Earth-based GPS and Galileo Global Navigation Satellite Systems (GNSS) at lunar distances. Operating on less than 20 watts of power, roughly the same as a laptop computer, it can determine a spacecraft’s precise position far beyond Earth orbit.
Lunar Navigation System
The NavCube3-mini payload builds on a series of navigation technology advancements developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, each extending GPS navigation to new record-breaking distances from Earth. The payload will fly aboard Intuitive Machines’ Altus-1 lunar relay satellite, the first of a planned network of lunar relay satellites being developed under the company’s Near Space Network Services contract with NASA.
The relays will provide communications and navigation support for missions operating at the Moon, including the challenging lunar South Pole region, where Artemis astronauts will land in 2028, and where direct communications with Earth can be difficult. By extending communications coverage and improving navigation services, the relay network will help realize NASA’s vision for a sustained human presence on the lunar surface.
Benefits of Lunar Navigation
The lunar navigation system will enable astronauts and rovers to operate more safely and efficiently on the Moon’s surface. It will also provide valuable performance data to support the development of future lunar navigation infrastructure. This technology is part of NASA’s broader strategy to develop communications and navigation services that work across both commercial providers and NASA’s networks.

- Extend communications coverage and improve navigation services for missions operating at the Moon
Future of Lunar Navigation
The delivery of NavCube3-mini marks another step toward building the communications and navigation infrastructure needed for long-term lunar exploration. Through partnerships with commercial providers like Intuitive Machines, NASA is building a more connected and capable lunar environment. As activity around the Moon continues to grow, these capabilities will enable lunar spacecraft and explorers to operate more safely, efficiently, and autonomously.
Lunar Navigation and Beyond
The success of the lunar navigation system will have significant implications for future space exploration. It will enable NASA to establish a sustained human presence on the lunar surface and eventually expand to other destinations in the solar system. The development of this technology is a crucial step towards achieving these goals and will have a lasting impact on the future of space exploration.
