The dream of establishing permanent human settlements on the Moon and Mars isn’t just science fiction anymore; it’s becoming an engineering reality. As we stand at the threshold of 2025, the convergence of artificial intelligence and advanced materials science is revolutionizing how we think about powering humanity’s next frontier. The challenges are immense: extreme temperatures, pervasive dust, intense radiation, and the complete absence of a power grid. Yet, the solutions emerging today are nothing short of extraordinary.
Unlike Earth, where we can simply plug into the grid, our future lunar and Martian outposts will need to generate, store, and distribute every watt of power independently. The stakes couldn’t be higher, from life support systems keeping astronauts alive to resource extraction operations that will fuel our expansion across the solar system. What makes 2025 particularly exciting is how AI is accelerating the discovery of materials that seemed impossible just a few years ago, while simultaneously optimizing energy systems for the harsh realities of space.
Revolutionary Solar Power: Beyond Silicon’s Limits
Perovskite Solar Cells Break New Ground
The solar power revolution in space is being led by perovskite solar cells, which are shattering efficiency records at an unprecedented pace. In April 2025, Chinese manufacturer LONGi achieved a world record efficiency of 34.85% for perovskite-silicon tandem solar cells, building on their previous record of 34.6% from June 2024. This isn’t just incremental progress; it’s a quantum leap that could revolutionize how we power space missions.
What makes these cells particularly exciting for space applications isn’t just their efficiency, but their unique properties. Merida Aerospace is developing perovskite solar cells specifically for low-Earth-orbit satellites, highlighting their remarkable resilience to high-energy radiation in space conditions, thanks to a self-healing effect. This self-healing capability, influenced by space temperatures, enhances light absorption and could dramatically extend the operational lifespan of solar arrays, a critical advantage when replacement missions cost millions of dollars.
The durability challenge that has long plagued perovskites is finally being addressed. Chinese researchers used a stabilizing ligand (para-toluenesulfonyl hydrazide) for all-inorganic perovskite cells, enabling them to maintain 80% efficiency after 1,500 hours of operation at 65°C and 800 hours at 85°C. Similarly, the University of Surrey found that alumina nanoparticles significantly enhanced the lifespan and stability of perovskite devices, maintaining high performance for more than two months.
Manufacturing Solar Panels on the Moon
Perhaps the most groundbreaking development of 2025 is the proposal by German scientists to manufacture halide perovskite cells locally on the Moon using regolith-based “moonglass”. This innovative approach could save an astonishing 99% of material transport weight and associated costs, while offering specific power ratios 20-100 times higher than traditional space solar solutions.
This isn’t just theoretical speculation. The European Space Agency is accelerating research into using lunar regolith for solar panel production due to growing concerns over germanium shortages, a critical material for traditional space power systems, exacerbated by export restrictions. ESA’s sustainability chief emphasizes that it is “not conceivable that we are bringing everything from Earth” for long-term exploration.
The 2025 Space Resources Challenge by ESA, in collaboration with the Luxembourg Space Agency and European Space Resources Innovation Centre, is focusing on innovative methods for excavation and beneficiation of lunar regolith, including preparing material for molten salt electrolysis to extract oxygen, laying the groundwork for broader in-situ resource utilization applications.
Vertical Solar Arrays for Lunar Poles
NASA’s Lunar Surface Innovation Initiative has identified the Lunar Vertical Solar Array Technology (VSAT) as a key supporting technology for surface power. This autonomous system features a 10-meter mast specifically designed to capture near-continuous sunlight at the lunar south pole, a region of high strategic interest due to its potential water ice reserves and periods of near-constant illumination. The vertical design cleverly adapts to the low sun angles at the lunar poles, allowing for extended periods of power generation compared to traditional flat-lying panels.
Nuclear Power: The Backbone of Deep Space Operations
Fission Power Systems for Mars
While solar power offers significant advantages, its limitations become apparent during long lunar nights (lasting 14 Earth days) or prolonged Martian dust storms. NASA has made a strategic decision, selecting nuclear fission power as the primary surface power generation technology for initial crewed missions to Mars. This decision underscores the recognition that sustained human presence on Mars requires a robust, sun-independent power source.
The Fission Surface Power (FSP) project, sponsored by NASA in collaboration with the Department of Energy and Idaho National Laboratory, aims to demonstrate a 40 kilowatt-electric nuclear reactor on the Moon by the end of the decade. This system is designed to support significant power demands, including peak loads of 60-70 kW for in-situ resource utilization activities and 20 kW for lunar habitats, with a 10-year operational life and a mass target of 6,000 kg.
Advanced Radioisotope Power Systems
Radioisotope Power Systems, particularly Multi-Mission Radioisotope Thermoelectric Generators (MMRTGs), have a proven track record powering deep-space probes like the Voyagers and Mars rovers such as Curiosity and Perseverance. These systems convert heat from the natural decay of plutonium-238 into electricity using solid-state thermocouples, with no moving parts, ensuring high reliability and long operational lifetimes.
The efficiency of these systems is being dramatically improved. Penn State scientists have developed high-entropy materials that achieved 15% conversion efficiency, a substantial increase from the 5-6% of current commercially available devices, with a record high figure of merit of 1.50 at 1060 K. This improvement means existing RTGs could be significantly smaller or produce substantially more power for the same size, critical for mass-constrained space missions.
Next-Generation Energy Storage Solutions
Solid-State Batteries: Safety Meets Performance
The energy storage revolution is being led by solid-state batteries, which replace the flammable liquid electrolyte with a solid material, dramatically enhancing safety by reducing the risk of thermal runaway and fire. NASA’s Sulfur Selenium solid-state battery, developed under the SABERS project, boasts an impressive energy density of 500 Wh/kg, effectively doubling the performance of traditional lithium-ion batteries.
This breakthrough is achieved through a novel combination of sulfur and selenium in the cathode with a lithium-metal anode. The SABERS battery also features a stackable architecture, reducing weight by 40% compared to traditional configurations, and incorporates “holey graphene” for enhanced conductivity and reduced mass. NASA envisions applications including lunar rovers and Mars helicopters, due to the battery’s resilience to extreme temperatures and radiation.
The commercial sector is also making significant strides. In May 2025, Factorial Inc. shipped its first solid-state lithium-metal battery cells for drone deployment, achieving up to 50% greater energy density than conventional lithium-ion batteries, enabling longer flight times and greater payload capacity for unmanned aerial systems.
Regenerative Fuel Cells: Closed-Loop Energy Systems
Regenerative Fuel Cells represent one of the most elegant solutions for long-duration energy storage in space. These systems operate in a closed loop: during periods of power generation, water is electrolyzed into hydrogen and oxygen, which are then stored. During periods of darkness or high demand, the fuel cell combines the stored hydrogen and oxygen to generate electricity and water, which is recycled back into the system.
In April 2025, Honda R&D announced plans to test its high-differential-pressure water electrolysis system on the International Space Station in collaboration with Sierra Space and Tec-Masters. This project is part of Honda’s vision for a regenerative fuel cell system that could provide advanced energy storage capable of supporting human life on the lunar surface. The system’s lightweight and compact design, along with reduced maintenance needs due to the absence of mechanical compression, addresses the critical need to minimize transportation costs for lunar development.
For Mars applications, regenerative fuel cells are particularly attractive due to the availability of carbon dioxide in the Martian atmosphere. NASA’s Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) on the Perseverance rover, which successfully produced oxygen from Martian atmospheric carbon dioxide, is a foundational step in demonstrating ISRU capabilities for fuel cell systems.
AI-Driven Materials Discovery: The Game Changer
Computational Materials Science Revolution
The complexity of designing materials for the extreme conditions of space, radiation, vacuum, and vast temperature swings has traditionally required decades of trial-and-error research. Artificial intelligence is changing this paradigm completely. The Artificial Intelligence for Advanced Materials 2025 (AI4AM2025) conference highlighted how AI is revolutionizing the prediction of new materials by enabling more efficient analysis of complex datasets, predicting material properties and behaviors with unprecedented accuracy.
This integration significantly reduces the time and cost involved in experimenting with new materials, as AI can identify promising candidates faster than traditional methods. Machine learning models can uncover patterns and insights from large-scale datasets that would be impossible for humans to detect, fundamentally accelerating the materials discovery process.
Generative AI: Designing Materials from Scratch
Microsoft’s MatterGen represents a breakthrough in materials design, acting as an idea generator that crafts detailed concepts of molecular structures using advanced algorithms to predict potential materials with unique properties. This generative approach is a radical departure from traditional methods of screening existing materials; it designs entirely new materials customized to defined parameters.
MatterSim complements MatterGen by applying rigorous computational analysis to predict which of those imagined materials are stable and viable, effectively filtering out what is physically possible from what is merely theoretical. MatterGen can generate materials with desired chemistry, mechanical, electronic, or magnetic properties, as well as combinations of different constraints.
Cornell University researchers demonstrated in May 2025 how physics-informed generative AI models can generate novel crystal structures that embed crystallographic symmetry and other fundamental principles, ensuring that AI-generated materials are not only mathematically possible but also chemically realistic.
Machine Learning for Lunar Construction
The application of AI extends beyond material discovery to actual construction processes. NASA’s Moon to Mars Planetary Autonomous Construction Technology (MMPACT) project is exploring large-scale, robotic 3D printing technology for construction on other planets using simulated lunar and Martian regolith. ICON, a partner in NASA’s 3D-Printed Habitat Challenge, has already built a 1,700-square-foot simulated Martian habitat, Mars Dune Alpha, demonstrating the feasibility of 3D printing structures from local resources.
Machine learning algorithms are being developed to ensure the quality of parts fabricated with lunar regolith-based materials using laser additive manufacturing methods. A project starting in October 2025 at UCL, in collaboration with ESA, aims to develop and optimize laser-based additive manufacturing for fabricating small parts like drills and solar panel support structures from lunar regolith.

The Integrated Future: Building Multi-Planetary Infrastructure
The vision for sustainable space exploration goes far beyond individual technologies; it requires a completely integrated approach where energy systems, advanced materials, and AI work in harmony. NASA’s Moon to Mars Architecture defines a continuously evolving blueprint for long-term, human-led scientific discovery in deep space, with a core objective to develop the power, communications, navigation, and resource utilization capabilities necessary to support human exploration.
This architecture envisions a global lunar utilization infrastructure where industry and international partners can maintain continuous robotic and human presence, fostering a robust lunar economy. The Lunar Surface Innovation Initiative has already advanced many lunar technologies, with numerous systems now en route or already on the Moon.
Central to this vision is the establishment of integrated power grids on planetary surfaces. Initial grid concepts for the Moon suggest a radial network that can expand, with recommendations for long-distance power transmission at 3 kV AC, 3-phase, and 1 kHz frequency, identified as the lightest solution for future growth into the hundreds of megawatt to gigawatt range. For Mars, a hybrid AC/DC grid, similar to those proposed for lunar colonies, is expected to offer advantages in energy efficiency, safety, and reliability.
The synergies between energy and AI are creating a positive feedback loop. AI accelerates the discovery and optimization of advanced materials for solar cells, batteries, and thermoelectric generators, directly enhancing their performance and durability in space. These improved energy systems, in turn, power AI-driven autonomous systems for exploration and construction. The data collected by these systems feeds back into AI models, further refining material designs and optimizing energy infrastructure.
This interconnected approach is essential for overcoming the immense challenges of off-world habitation. The Moon to Mars architecture, with its emphasis on interoperability and scalability, provides the framework where technology developed for lunar missions serves as a direct stepping stone for Mars, and eventually, the entire solar system.
The Road Ahead: 2025 and Beyond
As we progress through 2025, several critical milestones are shaping the future of space power systems. The testing of Honda’s regenerative fuel cell system on the ISS will validate closed-loop energy storage for lunar applications. The demonstration of 40 kWe nuclear fission power on the Moon by decade’s end will prove the viability of industrial-scale power for permanent human habitation.
Perhaps most importantly, the shift toward in-situ resource utilization is accelerating. The ability to manufacture solar panels from lunar regolith represents more than just cost savings; it’s a fundamental paradigm shift toward true self-sufficiency. When combined with AI-driven materials discovery and autonomous construction systems, we’re witnessing the emergence of technologies that could support not just outposts, but entire civilizations beyond Earth.
The advancements we’re seeing today in materials science and space technology are laying the groundwork for humanity’s next great leap. From self-healing materials to ultra-lightweight composites, the innovations emerging from 2025 will define the next century of space exploration.
