Scientists have hypothesized since the 1960s that the Sun is a source of ingredients that form water on the Moon. When a stream of charged particles known as the solar wind smashes into the lunar surface, the idea goes, it triggers a chemical reaction that could make water molecules.
Now, in the most realistic lab simulation of this process yet, NASA-led researchers have confirmed this prediction.
The finding, researchers wrote in a March 17 paper in JGR Planets, has implications for NASA’s Artemis astronaut operations at the Moon’s South Pole. A critical resource for exploration, much of the water on the Moon is thought to be frozen in permanently shadowed regions at the poles.
“The exciting thing here is that with only lunar soil and a basic ingredient from the Sun, which is always spitting out hydrogen, there’s a possibility of creating water,” Li Hsia Yeo, a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “That’s incredible to think about,” said Yeo, who led the study.
Solar wind flows constantly from the Sun. It’s made largely of protons, which are nuclei of hydrogen atoms that have lost their electrons. Traveling at more than one million miles per hour, the solar wind bathes the entire solar system. We see evidence of it on Earth when it lights up our sky in auroral light shows.
Computer-processed data of the solar wind from NASA’s STEREO spacecraft. Download here: https://svs.gsfc.nasa.gov/20278/ NASA/SwRI/Craig DeForest Most of the solar particles don’t reach the surface of Earth because our planet has a magnetic shield and an atmosphere to deflect them. But the Moon has no such protection. As computer models and lab experiments have shown, when protons smash into the Moon’s surface, which is made of a dusty and rocky material called regolith, they collide with electrons and recombine to form hydrogen atoms.
Then, the hydrogen atoms can migrate through the lunar surface and bond with the abundant oxygen atoms already present in minerals like silica to form hydroxyl (OH) molecules, a component of water, and water (H2O) molecules themselves.
Scientists have found evidence of both hydroxyl and water molecules in the Moon’s upper surface, just a few millimeters deep. These molecules leave behind a kind of chemical fingerprint — a noticeable dip in a wavy line on a graph that shows how light interacts with the regolith. With the current tools available, though, it is difficult to tell the difference between hydroxyl and water, so scientists use the term “water” to refer to either one or a mix of both molecules.
Many researchers think the solar wind is the main reason the molecules are there, though other sources like micrometeorite impacts could also help by creating heat and triggering chemical reactions.
In 2016, scientists discovered that water is released from the Moon during meteor showers. When a speck of comet debris strikes the moon, it vaporizes on impact, creating a shock wave in the lunar soil. With a sufficiently large impactor, this shock wave can breach the soil’s dry upper layer and release water molecules from a hydrated layer below. NASA’s LADEE spacecraft detected these water molecules as they entered the tenuous lunar atmosphere. NASA’s Goddard Space Flight Center Conceptual Image Lab Spacecraft measurements had already hinted that the solar wind is the primary driver of water, or its components, at the lunar surface. One key clue, confirmed by Yeo’s team’s experiment: the Moon’s water-related spectral signal changes over the course of the day.
In some regions, it’s stronger in the cooler morning and fades as the surface heats up, likely because water and hydrogen molecules move around or escape to space. As the surface cools again at night, the signal peaks again. This daily cycle points to an active source — most likely the solar wind—replenishing tiny amounts of water on the Moon each day.
To test whether this is true, Yeo and her colleague, Jason McLain, a research scientist at NASA Goddard, built a custom apparatus to examine Apollo lunar samples. In a first, the apparatus held all experiment components inside: a solar particle beam device, an airless chamber that simulated the Moon’s environment, and a molecule detector. Their invention allowed the researchers to avoid ever taking the sample out of the chamber — as other experiments did — and exposing it to contamination from the water in the air.
“It took a long time and many iterations to design the apparatus components and get them all to fit inside,” said McLain, “but it was worth it, because once we eliminated all possible sources of contamination, we learned that this decades-old idea about the solar wind turns out to be true.”
Using dust from two different samples picked up on the Moon by NASA’s Apollo 17 astronauts in 1972, Yeo and her colleagues first baked the samples to remove any possible water they could have picked up between air-tight storage in NASA’s space-sample curation facility at NASA’s Johnson Space Center in Houston and Goddard’s lab. Then, they used a tiny particle accelerator to bombard the dust with mock solar wind for several days — the equivalent of 80,000 years on the Moon, based on the high dose of the particles used.
They used a detector called a spectrometer to measure how much light the dust molecules reflected, which showed how the samples’ chemical makeup changed over time.
In the end, the team saw a drop in the light signal that bounced to their detector precisely at the point in the infrared region of the electromagnetic spectrum — near 3 microns — where water typically absorbs energy, leaving a telltale signature.
While they can’t conclusively say if their experiment made water molecules, the researchers reported in their study that the shape and width of the dip in the wavy line on their graph suggests that both hydroxyl and water were produced in the lunar samples.

In an open challenge, NASA is seeking innovative business models that propose new approaches to solving complex Earth science problems using unconventional computing methods and is holding an informational webinar on Monday, April 28.
The agency’s Beyond the Algorithm Challenge, sponsored by NASA’s Earth Science Technology Office, asks for proposals to more rapidly and accurately understand our home planet using transformative computing methods such as quantum computing, quantum machine learning, neuromorphic computing, in-memory computing, or other approaches.
The Beyond the Algorithm Challenge kicked off in March and consists of three phases. Participant submissions, which are due on July 25, will be evaluated based on creativity, technical feasibility, impact, business model evaluation, and presentation. Up to 10 finalists will be invited to present their ideas to a panel of judges at a live pitch event, and winners will a monetary prize.
For details about the challenge, interested participants can sign up for the informational webinar on Monday, April 28, here.
Using the vantage point of space, NASA’s observations of Earth increase our understanding of our home planet, improve lives, and safeguard our future. The capabilities of NASA’s Earth Science Division include developing new technology, delivering actionable science, and providing environmental information to meet the increased demand for more sophisticated, more accurate, more trustworthy, and more actionable environmental information for decision-makers and policymakers.
For example, rapid flood analysis is one area that may benefit from computing advancements. Flood hazards affect personal safety and land use, directly affecting individual livelihoods, community property, and infrastructure development and resilience. Advanced flood analysis capability enables contributions to protect and serve impacted communities, making a tangible difference in areas such as disaster preparedness, recovery, and resilience.
Advancements in computing capabilities show promise in overcoming processing power, efficiency, and performance limitations of conventional computing methods in addressing Earth science challenges like rapid flood analysis. Quantum computers offer a fundamentally different paradigm of computation and can solve certain classes of problems exponentially faster than their classical counterparts. Likewise, quantum machine learning offers the potential to reduce required training data or produce more accurate models. The emerging field of neuromorphic, or brain-inspired, computing holds significant promise for algorithm development optimized for high-speed, low power. And in-memory computing saves time and energy for data-heavy processes like artificial intelligence training.
Blue Clarity is hosting the Beyond the Algorithm Challenge on behalf of NASA. The NASA Tournament Lab, part of the Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate, manages the challenge. The program supports global public competitions and crowdsourcing as tools to advance NASA research and development and other mission needs.

GLOBE Mission Earth Supports Career Technical Education
The NASA Science Activation program’s GLOBE Mission EARTH (GME) project is forging powerful connections between career technical education (CTE) programs and real-world science, inspiring students across the United States to pursue careers in Science, Technology, Engineering, and Mathematics (STEM).
GME is a collaborative effort between NASA scientists, educators, and schools that brings NASA Earth science and the GLOBE Program into classrooms to support hands-on, inquiry-based learning. GLOBE (Global Learning and Observations to Benefit the Environment) is an international science and education program that provides students and the public with the opportunity to participate in data collection and the scientific process, contributing meaningfully to our understanding of the Earth system.
By connecting students directly to environmental research and NASA data, GME helps make science more relevant, engaging, and applicable to students’ futures. In CTE programs—where project-based and work-based learning are key instructional strategies—GME’s integration of GLOBE protocols offers students the chance to develop not only technical skills, but also essential data literacy and professional competencies like collaboration, critical thinking, and communication. These cross-cutting skills are valuable across a wide range of industries, from agriculture and advanced manufacturing to natural resources and public safety.
The real-world, hands-on approach of CTE makes it an ideal setting for implementing GLOBE to support STEM learning across industries. At Skyline High School in Oakland, California, for example, GLOBE has been embedded in multiple courses within the school’s Green Energy Pathway, originally launched by GLOBE partner Tracy Ostrom. Over the past decade, nearly 1,000 students have participated in GLOBE activities at Skyline. Many of these students describe their experiences with environmental data collection and interactions with NASA scientists as inspiring and transformative. Similarly, at Toledo Technology Academy, GME is connecting students with NASA science and renewable energy projects—allowing them to study how solar panels impact their local environment and how weather conditions affect wind energy generation.
To expand awareness of how GLOBE can enhance CTE learning and career preparation, WestEd staff Svetlana Darche and Nico Janik presented at the Educating for Careers Conference on March 3, 2025, in Sacramento, California. This event, sponsored by the California chapter of the Association for Career and Technical Education (ACTE), brought together over 2,600 educators dedicated to equipping students with the tools they need to succeed in an evolving job market. Darche and Janik’s session, titled “Developing STEM Skills While Contributing to Science,” showcased GLOBE’s role in work-based learning and introduced new federal definitions from the Carl D. Perkins Act (Perkins V) that emphasize:
Interactions with industry professionals A direct link to curriculum and instruction First-hand engagement with real-world tasks in a given career field GLOBE’s approach to scientific data collection aligns perfectly with these criteria. Janik led 40 educators through a hands-on experience using the GLOBE Surface Temperature Protocol, demonstrating how students investigate the Urban Heat Island Effect while learning critical technical and analytical skills. By collecting and analyzing real-world data, students gain firsthand experience with the tools and methods used by scientists, bridging the gap between classroom learning and future career opportunities.
Through GME’s work with CTE programs, students are not only learning science—they are doing science. These authentic experiences inspire, empower, and prepare students for careers where data literacy, scientific inquiry, and problem-solving are essential. With ongoing collaborations between GLOBE, NASA, and educators nationwide, the next generation of STEM professionals is already taking shape—one real-world investigation at a time.
GME is supported by NASA under cooperative agreement award number NNX16AC54A and is part of NASA’s Science Activation Portfolio.
