30-second brief
NASA delivered the NavCube3-mini navigation payload to Intuitive Machines on July 13 for integration into the Altus-1 lunar relay satellite. The device uses Earth-based GPS and Galileo signals to provide positioning data for lunar missions.
One-minute read
NASA has delivered the NavCube3-mini navigation payload to Intuitive Machines for installation on the Altus-1 lunar relay satellite. Weighing 3.5 pounds and consuming under 20 watts, the compact device uses GPS and Galileo GNSS signals from Earth to track precise positions in lunar orbit. Developed at Goddard Space Flight Center, the payload completed environmental and performance testing prior to delivery. Altus-1 is part of Intuitive Machines' Near Space Network Services contract with NASA, designed to establish communication and navigation infrastructure for commercial landers, rovers, and future Artemis crewed missions to the Moon.
Why this matters
Extending Earth-based navigation signals to lunar distances allows commercial and government missions to navigate more accurately and autonomously, supporting sustained human presence on the Moon.
Background
Direct communication and precise navigation near the Moon, particularly at the lunar South Pole, present severe technical challenges. NASA relies on commercial partnerships under programs like Near Space Network Services to build scalable orbital infrastructure.

NASA delivered the NavCube3-mini payload to Intuitive Machines on July 13 for integration into Altus-1, the company's first lunar relay satellite. The compact payload will serve as a key technology demonstration to validate Earth-based navigation signals in lunar orbit.
Weighing 3.5 pounds and about half the size of a shoebox, NavCube3-mini operates on less than 20 watts of power. It is designed to process signals from Earth's GPS and Galileo Global Navigation Satellite Systems at lunar distances, allowing spacecraft to determine their precise position far beyond Earth orbit.
The payload was developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Prior to delivery, it underwent extensive testing, including launch vibration simulations, thermal vacuum exposure, and electromagnetic compatibility assessments to ensure flight readiness.
Altus-1 is being developed under Intuitive Machines' Near Space Network Services contract with NASA. The relay satellite network aims to provide communications and navigation support for future Moon missions, including operations near the lunar South Pole where astronauts under the Artemis program are expected to land.
