<\/figure>\nIM-1, the first NASA Commercial Launch Program Services launch for Intuitive Machines\u2019 Nova-C lunar lander, will carry multiple payloads to the Moon, including Lunar Node-1, demonstrating autonomous navigation via radio beacon to support precise geolocation and navigation among lunar orbiters, landers, and surface personnel. NASA\u2019s CLPS initiative oversees industry development of small robotic landers and rovers to support NASA\u2019s Artemis campaign. <\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\n\u201cImagine getting verification from a lighthouse on the shore you\u2019re approaching, rather than waiting on word from the home port you left days earlier,\u201d said Evan Anzalone, principal investigator of LN-1 and a navigation systems engineer at NASA\u2019s Marshall Space Flight Center in Huntsville, Alabama. \u201cWhat we seek to deliver is a lunar network of lighthouses, offering sustainable, localized navigation assets that enable lunar craft and ground crews to quickly and accurately confirm their position instead of relying on Earth.\u201d<\/p>\n
The system is designed to operate as part of a broader navigation infrastructure, anchored by a series of satellites in lunar orbit as being procured under NASA\u2019s Lunar Communications Relay and Navigation Systems<\/a> project. Together, future versions of LN-1 would utilize LunaNet-defined standards<\/a> to provide interoperable navigation reference signals from surface beacons as well as orbital assets.<\/p>\nCurrently, navigation beyond Earth is heavily reliant on point-to-point services provided by NASA\u2019s Deep Space Network<\/a>, <\/em>an international array of giant radio antennas which transmit positioning data to interplanetary spacecraft to keep them on course. These measurements typically are relayed back to Earth and processed on the ground to deliver information back to the traveling vehicle.<\/p>\nBut when seconds count during orbital maneuvers, or among explorers traversing uncharted areas of the lunar surface, LN-1 offers a timely improvement, Anzalone said.<\/p>\n

<\/figure>\nLunar Node-1, an autonomous navigation payload that will change how human explorers safely traverse the Moon\u2019s surface and live and work in lunar orbit, awaits liftoff as part of Intuitive Machines\u2019 IM-1 mission, its first under NASA\u2019s Commercial Lunar Payload Services initiative. LN-1 was developed, built, and tested at NASA\u2019s Marshall Space Flight Center in Huntsville, Alabama. <\/div>\nNASA\/Intuitive Machines<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\nThe CubeSat-sized experiment is one of six payloads included in the NASA delivery manifest for Intuitive Machines of Houston, which will be launched via a SpaceX Falcon 9 from Cape Canaveral, Florida. Designated IM-1, the launch is the company\u2019s first for NASA\u2019s CLPS initiative, which oversees industry development, testing, and launch of small robotic landers and rovers supporting NASA\u2019s Artemis<\/a> campaign.<\/p>\nThe Nova-C lander is scheduled to touch down near Malapert A, a lunar impact crater in the Moon\u2019s South Pole region.<\/p>\n
LN-1 relies on networked computer navigation software known as MAPS (Multi-spacecraft Autonomous Positioning System<\/a>). Developed by Anzalone and researchers at NASA Marshall, MAPS was successfully tested on the International Space Station in 2018 using NASA\u2019s Space Communications and Navigation testbed<\/a>.<\/p>\nEngineers at NASA Marshall conducted all structural design, thermal and electronic systems development, and integration and environmental testing of LN-1 as part of the NASA-Provided Lunar Payloads project<\/a> funded by the agency\u2019s Science Mission Directorate<\/a>. Anzalone and his team delivered the payload in 2021, having performed the payload build during the COVID pandemic. Since then, they refined the operating procedures, conducted thorough testing of the integrated flight system, and in October 2023, oversaw installation of LN-1 on Intuitive Machines\u2019 lander.<\/p>\n\n
