NASA has announced a call for proposals to develop the lunar technologies needed to support exploration and establish a long-term human presence at the Moon’s South Pole.
The agency is targeting major gaps in power generation, oxygen production, manufacturing and advanced materials as it works towards a future Moon Base.
The call forms part of NASA’s Next Space Technologies for Exploration Partnerships-3, or NextSTEP-3, and focuses on technologies that could eventually operate in the harsh lunar environment.
NASA wants competing solutions to be matured and demonstrated, helping move critical systems closer to operational use.
The result could be a new generation of lunar infrastructure capable of producing power and resources locally while reducing dependence on supplies launched from Earth.
NASA says the programme will support US-led capabilities while allowing participation from private companies, universities, non-profit organisations and international partners working through US-led teams.
Speaking on the initiative, Greg Stover, director of NASA’s Advanced Research and Technology Division, commented: “NASA is accelerating the development of key technologies and closing critical gaps needed for long-term human exploration at the Moon.
“Partnering with industry will strengthen the US industrial base as we mature the capabilities and infrastructure needed for a sustainable lunar presence.”
Five technologies could shape lunar operations
The Lunar Enabling Infrastructure Accelerator (LEIA) solicitation identifies five priority areas.
One is vertical solar array technology, designed to provide reliable power generation, distribution and energy storage in the challenging lighting conditions around the lunar poles.
NASA is also seeking in situ resource utilisation (ISRU) systems that can extract oxygen from lunar regolith. Oxygen is chemically bound within the rocks and dust covering the Moon, making the material a potentially important local resource for future explorers.
A third focus is the radioisotope Stirling generator, which uses heat from radioactive material to produce electricity. Such systems could provide power in locations where conventional solar generation is difficult or impossible.
The remaining areas are in-space advanced manufacturing and innovative nanomaterials production. Manufacturing materials and components locally could reduce the need for repeated resupply missions from Earth and give future lunar operations greater flexibility.
The engineering challenge at the lunar South Pole
NASA’s choice of the South Pole is not simply about where to put a base.
The region offers scientific and resource opportunities, but its terrain and lighting conditions also create some of the most difficult engineering challenges on the Moon.
Deep craters, rugged terrain and permanently shadowed areas can experience extreme cold, while the Sun remains low on the horizon. That makes dependable power especially important for equipment that must operate for extended periods.
Some permanently shadowed regions are also of interest because they may contain frozen volatiles, including water ice. Accessing these areas could eventually support resource utilisation and reduce the amount of material future missions need to bring from Earth.
NASA’s plan for a Moon Base
NASA is now pursuing a phased Moon Base strategy, rather than attempting to construct a permanent settlement in a single mission.
The agency’s approach begins with robotic missions and technology demonstrations, followed by the deployment of foundational infrastructure such as power, communications, transportation and logistics systems.
Later phases are intended to support astronauts living and working on the lunar surface for increasingly long periods.
The Artemis programme forms part of this wider effort. NASA’s current architecture targets the first crewed lunar landing in early 2028, while Artemis V is expected to begin building the foundations of the Moon Base later that year. The agency plans to increase the cadence of lunar missions thereafter.
Building infrastructure before the base
That makes developing lunar technologies more than a supporting exercise.
Reliable power, local resource extraction and the ability to manufacture materials on the Moon could determine how far astronauts can operate from their initial landing sites.
NASA is already developing technologies for power generation, regolith excavation, resource extraction, construction and communications as part of its wider lunar surface technology programme.
The latest solicitation adds another layer to that effort by targeting lunar technologies that could help turn individual Moon missions into a scalable infrastructure network.
If successful, these systems could provide some of the basic building blocks needed to move from short-duration visits to a sustained human presence on the Moon.
