NASA and IBM unveiled the Lunar Foundation Model, an open-source AI model trained on decades of lunar observation data from four missions. Available on Hugging Face, it outperforms existing methods by up to 23% in identifying ice deposits, craters and volcanic features to support NASA's Artemis program.

NASA and IBM Unveil Groundbreaking Lunar Foundation Model

NASA and IBM released the Lunar Foundation Model on Thursday, marking a significant advancement in lunar research capabilities

1

. This open-source AI model, now available on Hugging Face, represents the first publicly accessible tool designed to process and analyze decades of lunar observation data at scale

2

. The model joins the Prithvi family of foundation models, which already includes applications for weather, climate and earth observation

1

.

Trained on more than 30 layers of data collected by nine instruments across four NASA missions, including the Lunar Reconnaissance Orbiter, the Lunar Foundation Model addresses a critical bottleneck in lunar research

3

. Previously, scientists had to manually examine maps and images or rely on low-resolution machine learning models designed for specific tasks

1

. The new model integrates observations captured in multiple data formats, viewing angles and spatial scales, eliminating the need to build custom AI models from scratch for each research question

Superior Performance in Identifying Critical Lunar Features

In benchmark tests, the AI model demonstrated remarkable accuracy improvements over widely used methods. The model outperformed SwinV2-B, a Microsoft-trained vision system commonly used as a baseline for image analysis tasks, by up to 23% in identifying key features on the lunar surface

3

. For crater detection specifically, it surpassed SwinV2-B by nearly 19% while using only half the training labels

4

.

The model's capabilities extend beyond simple feature recognition. It can identify ice deposits in permanently shadowed regions, map craters to select safe landing sites, and analyze volcanic features called Irregular Mare Patches

1

. When estimating polar ice prospectivity within the top meter of regolith, the Lunar Foundation Model reduced errors by up to 22% compared to SwinV2-B

4

. This accuracy matters because lunar ice indicates the presence of water and oxygen, resources considered essential for establishing a future moon base and producing rocket fuel for missions to Mars

Overcoming Unique Technical Challenges in Lunar Data Processing

Developing the Lunar Foundation Model required solving problems unique to lunar observation. Dr. Juan Bernabé-Moreno, director of IBM Research Europe, explained that the Moon's lack of atmosphere creates extreme lighting conditions that don't exist on Earth

5

. Without atmospheric scattering to soften shadows, lunar shadows appear knife-edged and pitch black, meaning shadowed pixels carry no information

5

. A single crater can look completely different depending on when it was photographed.

To address this, researchers incorporated explicit metadata describing solar angles and spacecraft positions directly into the model's architecture

4

. This allows the model to recognize actual terrain features rather than being misled by shadows. The team also employed masked-token learning, a technique where the AI is shown portions of lunar tiles and must predict concealed information across millions of examples

4

.

Traditional training methods proved disastrous for lunar applications. Bernabé-Moreno described initial attempts as a "complete disaster" because many craters look similar when photographed from orbit

5

. The solution involved dividing the Moon into wedges like an orange and completely separating training wedges from testing wedges, providing the model with necessary consistency

First-of-Its-Kind Dataset Enables Future Research

Alongside the Lunar Foundation Model, IBM and NASA scientists compiled SomBench, the first open-source lunar dataset of its kind

4

. This dataset brings together tens of thousands of maps and images collected by instruments from NASA's Lunar Reconnaissance Orbiter and Gravity Recovery and Interior Laboratory missions, as well as Japan's Selenological and Engineering Explorer

5

.

SomBench organizes nearly 2 million overlapping map patches into aligned tracks, ensuring data from different instruments, resolutions or angles all correspond when capturing the same lunar tiles

4

. The dataset incorporates over 30 spatially-aligned layers, combining high-resolution optical cameras, laser altimeters, radar reflectance tools and spectrometers that measure elemental density

2

.

"That alone is a massive scientific contribution, because put the model aside: the community now has a co-registered dataset with more than two million data points," Bernabé-Moreno noted

5

. NASA's chief science data officer Kevin Murphy emphasized that collecting data is only part of the job, stating the agency must also make data easier for scientists to explore and use

.

Supporting the Artemis Program and Beyond

The timing of this release aligns with NASA's Artemis program, which plans to return astronauts to the Moon in 2028

3

. The program aims to test new technology for a sustained lunar presence and prepare for future Mars missions. Campbell Watson, senior research manager at IBM Research, explained that by making the model and dataset publicly available, the organizations want to provide the global scientific community with a shared foundation that researchers can adapt to new questions about the moon

.

The model recently demonstrated its practical capabilities when a SpaceX Falcon 9 rocket crashed into the Moon on August 5. When IBM fed an image of the impact to the model, it correctly identified the crash site as a new crater on its first attempt, despite the impact closely overlapping with an existing crater

For researchers interested in using the model, hardware requirements vary depending on the application. Most fine-tuning experiments were conducted using Nvidia A100 GPUs, though smaller-scale experiments and inference workloads may be possible on more modest hardware

2

. Watch for the scientific community to build specialized applications on this foundation, potentially uncovering discoveries about lunar ice distribution, crater formation patterns and volcanic activity that could shape future moon explorations and planetary AI applications.
