In July 2023, Astrobotic Technology, a Pittsburgh-based aerospace company, secured a $34.6 million partnership with NASA under the Tipping Point program to demonstrate power transmission on the lunar surface. This initiative, named LunaGrid-Lite, aims to showcase the first high-voltage power transmission across the Moon's surface, marking a significant advancement in lunar infrastructure development.

Overview of LunaGrid-Lite
LunaGrid-Lite is designed to demonstrate the transmission of 1 kilowatt (kW) of power from an Astrobotic lunar lander to a tethered rover over a distance of 1 kilometer. The mission involves deploying a 6U CubeRover, which will unreel the cable from the lander and receive power transmitted through it. This demonstration serves as a precursor to Astrobotic's LunaGrid service, which aims to provide commercial power services to future lunar missions. ([astrobotic.com](
Significance of the Mission
The successful demonstration of power transmission on the lunar surface is crucial for the sustainability of long-term lunar operations. Reliable power is essential for various lunar activities, including scientific research, habitat operations, and in-situ resource utilization. By validating the technology through LunaGrid-Lite, Astrobotic and NASA aim to lay the groundwork for future lunar infrastructure that can support both crewed and robotic missions. ([astrobotic.com](
Technological Developments
To facilitate the LunaGrid-Lite mission, Astrobotic has developed a lunar-optimized, ultra-light cable capable of transmitting 1 kW of alternating current (AC) power. In July 2024, the company successfully demonstrated power transfer through 1,000 feet of this cable, measuring key parameters such as power factor, cable efficiency, voltage drop, and reactive power. These tests confirmed the cable's ability to transmit power at the desired voltage and frequency, exceeding expected performance models. ([astrobotic.com](
Project Milestones
As of August 2025, the LunaGrid-Lite project has completed its Critical Design Review (CDR), marking the end of the design and planning phase. The project has progressed to the fabrication and assembly of flight components, with plans to deploy the system on the lunar surface as early as 2026. This milestone indicates the project's readiness for flight and its potential to validate surface power delivery on the Moon. ([astrobotic.com](
Implications for Future Lunar Missions
The success of LunaGrid-Lite is expected to have far-reaching implications for future lunar missions. By demonstrating the feasibility of power transmission on the lunar surface, the mission paves the way for the establishment of sustainable lunar infrastructure. This infrastructure is vital for supporting NASA's Artemis program, which aims to return humans to the Moon and establish a long-term presence. Additionally, the technology developed through LunaGrid-Lite could benefit international space agencies and commercial enterprises planning lunar operations. ([astrobotic.com](
Conclusion
Astrobotic's LunaGrid-Lite mission represents a significant step forward in lunar exploration and infrastructure development. By demonstrating the transmission of high-voltage power across the lunar surface, the mission addresses a critical need for sustainable energy solutions on the Moon. The successful implementation of this technology will be instrumental in supporting future lunar missions, both crewed and robotic, and in establishing a permanent human presence on the Moon.
