NASA delivered the NavCube3-mini payload on July 13 to Intuitive Machines for integration into Altus-1, the company\u2019s 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\u2019s future Moon Base<\/a>.<\/p>\n

About half the size of a shoebox and weighing just 3.5 pounds, NavCube3-mini<\/a> is a compact but powerful navigation receiver designed to use signals from Earth-based GPS and Galileo Global Navigation Satellite Systems (GNSS)<\/a> at lunar distances. Operating on less than 20 watts of power, roughly the same as a laptop computer, it can determine a spacecraft\u2019s precise position far beyond Earth orbit. The compact payload builds on a series of navigation technology advancements developed at NASA\u2019s Goddard Space Flight Center<\/a> in Greenbelt, Maryland, each extending GPS navigation to new record-breaking distances<\/a> from Earth.<\/p>\n

The payload will fly aboard Intuitive Machines\u2019 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<\/a> with NASA. The relays<\/a> 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\u2019s vision for a sustained human presence on the lunar surface.<\/p>\n
