A new open-source artificial intelligence model trained on roughly 2 million lunar image tiles can map craters, identify unusual volcanic terrain and estimate where ice may remain stable near the Moon’s poles, NASA and IBM announced Thursday. The NASA-IBM Lunar Foundation Model combines more than 1 million high-resolution camera images with nearly 964,000 multispectral images, giving researchers a reusable technical foundation for several kinds of lunar analysis rather than a separate model for each task.

The public [NASA release](https://science.nasa.gov/science-research/artificial-intelligence-lunar-foundation-model/?ref=theamericanquorum.com) describes the system as one of the first open-source foundation models built specifically for lunar science. Its weights, downstream models, benchmark data and code are available for outside testing. That openness matters because the model’s value will depend not only on benchmark performance reported by its creators, but also on whether independent researchers can reproduce results and adapt the system reliably to different instruments, lighting conditions and scientific questions.

In initial evaluations, the model matched or exceeded several strong baselines across crater mapping and segmentation of irregular mare patches, while showing a clearer advantage in estimating polar ice stability. NASA and IBM said performance improved by as much as 23% on key surface-identification tasks, according to [Reuters](https://www.reuters.com/science/ibm-nasa-launch-ai-model-help-map-ice-craters-moon-2026-09-10/?ref=theamericanquorum.com). Those results are promising, but they measure performance on defined research tasks, not a completed landing decision or proof of recoverable water.

## A general model for lunar data

Foundation models are trained on large datasets so their learned representations can be adapted to many downstream tasks with relatively small amounts of labeled data. In lunar research, that approach can reduce the need for scientists to design and train a specialized model from scratch each time they want to count craters, segment a geological formation or compare surface changes. The new model acts as a common visual backbone that can be fine-tuned for a specific scientific problem.

The training data draw primarily from NASA’s Lunar Reconnaissance Orbiter, or LRO, which has studied the Moon since 2009\. The orbiter’s [mission record](https://science.nasa.gov/mission/lro/?ref=theamericanquorum.com) includes nearly global surface mapping along with measurements of temperature, composition and radiation. NASA says the volume of LRO data exceeds that of all its other planetary missions combined, making the archive valuable but difficult to examine exhaustively through manual review.

The model also incorporates imagery and terrain information from NASA’s Gravity Recovery and Interior Laboratory and Lunar Prospector missions, as well as Japan’s Selenological and Engineering Explorer. Combining modalities can help the system recognize relationships that are difficult to extract from one image type alone. High-resolution photographs show fine surface features, while multispectral observations and terrain layers provide information about composition, elevation and illumination.

## Three tests with practical value

Crater detection is the most intuitive application. Scientists use the number, size and distribution of impact craters to estimate the relative age of lunar surfaces and reconstruct parts of the solar system’s history. Automating detection across vast archives can accelerate that work and make it easier to compare regions consistently, although human review remains important when shadows, overlapping rims or low-resolution imagery create ambiguity.

A second task involves irregular mare patches, small volcanic features that appear younger than much of the surrounding terrain. Mapping them helps researchers test explanations of the Moon’s volcanic and thermal evolution. The model can segment those features more quickly than a manual search, allowing scientists to devote more time to interpreting their distribution and deciding which locations warrant closer observation.

The third application, polar ice prospectivity, has the clearest operational relevance. Permanently shadowed craters can remain cold enough to preserve ice for billions of years. NASA’s overview of [lunar water](https://science.nasa.gov/moon/moon-water-and-ices/?ref=theamericanquorum.com) explains that ice deposits could reveal how water reached and moved across the Moon. In a future exploration program, accessible water might also support drinking supplies, oxygen production or propellant, but prospectivity maps identify likely locations rather than verifying the quantity, purity or extractability of a deposit.

## Open access broadens the test

NASA and IBM published the model collection on [Hugging Face](https://huggingface.co/collections/nasa-ibm-ai4science/nasa-ibm-lunar-fm-and-downstream-models?ref=theamericanquorum.com), including separate downstream versions for crater detection, ice prospectivity and irregular mare patch segmentation. The release gives universities and smaller research groups access to a system that would be expensive to train independently. It also creates a shared baseline for comparing new approaches rather than forcing each laboratory to assemble a different starting point.

The associated [code repository](https://github.com/NASA-IMPACT/NASA-IBM-Lunar-Foundation-Model?ref=theamericanquorum.com) provides fine-tuning and inference tools, integration with the open-source TerraTorch framework and configurations for the downstream tasks. NASA has also released machine-learning-ready datasets and benchmark collections. The repository notes that pretraining code is not included, a limitation researchers will need to consider when evaluating how fully the original training process can be reproduced.

Open weights and code do not automatically eliminate other barriers. Running a large vision model still requires computing resources, technical expertise and careful data handling. Researchers must also examine whether benchmark datasets contain geographic or sensor biases, whether training images overlap with evaluation material and how model errors change across regions that receive extreme or inconsistent illumination.

## Why lunar imagery is difficult

The Moon presents unusual computer-vision problems. With almost no atmosphere, surface appearance is shaped heavily by the angle of sunlight, and near the poles the same feature can look dramatically different across observations. Deep shadows can conceal crater floors, while bright slopes can reduce visible texture. NASA cautions that changing illumination may affect the visibility of smaller craters even when the underlying terrain is unchanged.

Resolution adds another constraint. The training archive combines imagery ranging from approximately 1 meter to 100 meters per pixel, meaning that one data layer may reveal a boulder-scale feature while another captures only its broader geological setting. A model must learn useful connections across those scales without treating every difference as a physical change. Its predictions are therefore best viewed as tools for prioritizing expert analysis, not substitutes for instrument calibration or geological judgment.

The companion [technical report](https://huggingface.co/nasa-ibm-ai4science/NASA-IBM-Lunar-Foundation-Model/blob/main/NI%5FLFM%5FTechnical%5FReport.pdf?ref=theamericanquorum.com) and benchmarks will allow specialists to inspect architecture, training choices and task-specific performance. The most important next evidence will come from independent evaluation on data the model’s developers did not select, including observations from other missions and newly collected images. A 23% improvement on one benchmark can be meaningful without implying the same gain across every lunar region or scientific objective.

## AI becomes scientific infrastructure

The lunar model is part of a broader NASA-IBM effort to build reusable AI systems for science. Earlier Prithvi models have addressed Earth observation, weather, floods, crops and hurricanes, while a solar model has been developed for space-weather forecasting. NASA’s [AI strategy](https://science.nasa.gov/artificial-intelligence-science/?ref=theamericanquorum.com) frames these systems as a way to extract more value from large public datasets that are growing faster than researchers can examine them manually.

That approach can change the economics of scientific software. Training one broadly useful model and distributing it openly allows many teams to share the high initial cost, then spend their resources on validation and specialized applications. It can also improve comparability across studies if researchers report results against the same benchmarks. The trade-off is that a widely adopted base model may propagate its blind spots across many projects, making documentation and independent testing essential.

The immediate mission context is NASA’s [Artemis program](https://www.nasa.gov/humans-in-space/artemis/?ref=theamericanquorum.com), which is intended to build experience for sustained lunar exploration and later missions to Mars. Better maps could help narrow candidate landing areas, identify terrain hazards and prioritize sites for direct resource measurements. Yet the model does not choose a landing site on its own; engineering constraints, communications, lighting, scientific goals and direct observations all remain part of that decision.

## What the release establishes

The NASA-IBM release demonstrates that a single pretrained system can perform competitively across several lunar mapping tasks and that its creators are making core assets available for scrutiny. It does not establish that every prediction is accurate, that suspected ice can be extracted or that automated analysis can replace planetary scientists. Those distinctions are especially important when an AI result influences expensive missions or safety-critical planning.

The next phase will test whether the model becomes a durable research platform rather than a successful demonstration. Uptake by independent teams, performance on new mission data, transparent reporting of failures and measurable reductions in analysis time will provide stronger evidence of operational value. For now, NASA and IBM have lowered the technical barrier to applying advanced computer vision to the Moon and opened the system to the scientific community that must determine how far its advantages extend.
