For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. The full artist’s concept illustration and full caption is shown below. Credits:
NASA, ESA, CSA, Ralf Crawford (STScI) Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system.
Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star 155 light-years away using detailed data known as spectra from NASA’s James Webb Space Telescope. (The term water ice specifies its makeup, since many other frozen molecules are also observed in space, such as carbon dioxide ice, or “dry ice.”) In 2008, data from NASA’s retired Spitzer Space Telescope hinted at the possibility of frozen water in this system.
“Webb unambiguously detected not just water ice, but crystalline water ice, which is also found in locations like Saturn’s rings and icy bodies in our solar system’s Kuiper Belt,” said Chen Xie, the lead author of the new paper and an assistant research scientist at Johns Hopkins University in Baltimore, Maryland.
All the frozen water Webb detected is paired with fine dust particles throughout the disk — like itsy-bitsy “dirty snowballs.” The results published Wednesday in the journal Nature.
Astronomers have been waiting for this definitive data for decades. “When I was a graduate student 25 years ago, my advisor told me there should be ice in debris disks, but prior to Webb, we didn’t have instruments sensitive enough to make these observations,” said Christine Chen, a co-author and associate astronomer at the Space Telescope Science Institute in Baltimore. “What’s most striking is that this data looks similar to the telescope’s other recent observations of Kuiper Belt objects in our own solar system.”
Water ice is a vital ingredient in disks around young stars — it heavily influences the formation of giant planets and may also be delivered by small bodies like comets and asteroids to fully formed rocky planets. Now that researchers have detected water ice with Webb, they have opened the door for all researchers to study how these processes play out in new ways in many other planetary systems.
Image: Debris Disk Around Star HD 181327 (Artist’s Concept)
For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. All the frozen water detected by Webb is paired with fine dust particles throughout the disk. The majority of the water ice observed is found where it’s coldest and farthest from the star. The closer to the star the researchers looked, the less water ice they found. NASA, ESA, CSA, Ralf Crawford (STScI) Rocks, Dust, Ice Rushing Around
The star, cataloged HD 181327, is significantly younger than our Sun. It’s estimated to be 23 million years old, compared to the Sun’s more mature 4.6 billion years. The star is slightly more massive than the Sun, and it’s hotter, which led to the formation of a slightly larger system around it.
Webb’s observations confirm a significant gap between the star and its debris disk — a wide area that is free of dust. Farther out, its debris disk is similar to our solar system’s Kuiper Belt, where dwarf planets, comets, and other bits of ice and rock are found (and sometimes collide with one another). Billions of years ago, our Kuiper Belt was likely similar to this star’s debris disk.
“HD 181327 is a very active system,” Chen said. “There are regular, ongoing collisions in its debris disk. When those icy bodies collide, they release tiny particles of dusty water ice that are perfectly sized for Webb to detect.”
Frozen Water — Almost Everywhere
Water ice isn’t spread evenly throughout this system. The majority is found where it’s coldest and farthest from the star. “The outer area of the debris disk consists of over 20% water ice,” Xie said.
The closer in the researchers looked, the less water ice they found. Toward the middle of the debris disk, Webb detected about 8% water ice. Here, it’s likely that frozen water particles are produced slightly faster than they are destroyed. In the area of the debris disk closest to the star, Webb detected almost none. It’s likely that the star’s ultraviolet light vaporizes the closest specks of water ice. It’s also possible that rocks known as planetesimals have “locked up” frozen water in their interiors, which Webb can’t detect.
This team and many more researchers will continue to search for — and study — water ice in debris disks and actively forming planetary systems throughout our Milky Way galaxy. “The presence of water ice helps facilitate planet formation,” Xie said. “Icy materials may also ultimately be ‘delivered’ to terrestrial planets that may form over a couple hundred million years in systems like this.”
The researchers observed HD 181327 with Webb’s NIRSpec (Near-Infrared Spectrograph), which is super-sensitive to extremely faint dust particles that can only be detected from space.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

As NASA partners with American industry to deliver science and technology payloads to the Moon, a dedicated team behind the scenes ensures every mission is grounded in strategy, compliance, and innovation. Leading that effort is Aubrie Henspeter, who advises all aspects of procurement for NASA’s Commercial Lunar Payload Services (CLPS) initiative—one of the cornerstone projects supporting the Artemis campaign.
Official portrait of Aubrie Henspeter. NASA/Bill Stafford With 20 years at NASA, Henspeter brings multifaceted experience to her role as CLPS procurement team lead in the Lunar & Planetary Exploration Procurement Office at Johnson Space Center in Houston. Her job is equal parts problem-solving, mentoring, and strategizing—all focused on enabling commercial partners to deliver NASA payloads to the lunar surface faster, more affordably, and more efficient than ever before.
“It’s been a great experience to see the full lifecycle of a project—from soliciting requirements to launching to the Moon,” said Henspeter. “We work to continuously adjust as the lunar industry grows and improve procurement terms and conditions by incorporating lessons learned.”
Henspeter leads a team of six contracting officers and contract specialists, managing workload priorities and supporting the continuity of seven commercial missions currently on contract. She also helps shape upcoming contract opportunities for future lunar deliveries, constantly seeking creative procurement strategies within a commercial firm-fixed-price framework.
NASA launched the CLPS initiative in 2018 to create a faster, more flexible way to partner with commercial companies for lunar deliveries. Thirteen vendors are participating as part of a multi-award contract, each eligible to compete for individual task orders to deliver NASA science and technology payloads to the Moon. These deliveries support Artemis goals by enabling new discoveries, testing key technologies, and preparing for long-term human exploration on the lunar surface.
Aubrie Henspeter receives the 2023 JSC Director’s Commendation Award from NASA Acting Associate Administrator Vanessa Wyche, right, and Johnson Space Center’s Acting Director Steve Koerner, far left, joined by her sons Elijah and Malik Merrick.NASA/James Blair In May 2023, Henspeter received the NASA Exceptional Service Medal for her leadership on CLPS from 2018–2023. For her, the recognition reflects the team’s spirit and collaboration.
“I genuinely enjoy working on this project because of its lean, adaptable approach and the amazing team involved,” she said. “When all of us across NASA work together we are the most successful and can achieve our mission.”
That sense of collaboration and adaptability has shaped many of the insights Henspeter has gained throughout her career—lessons she now applies daily to help the team stay aligned and prepared.
One of those key lessons: always keep the contract current.
“It’s all good until it isn’t, and then everyone asks—what does the contract say?” she said. “Open communication and up-to-date documentation, no matter how minor the change, are essential.”
Over the course of her career, Henspeter has learned to prioritize preparation, adaptability, and strong working relationships.
“Preparation in procurement is conducting thorough market research, understanding the regulations, finding the gray areas, and developing a strategy that best meets the customer’s needs,” she said. “Adaptability means staying committed to the goal while remaining open and flexible on how to get there.”
That philosophy has helped her navigate everything from yearlong international contract negotiations with foreign partners to pivoting a customer from a sole-source request to a competitive procurement that ultimately saved costs and expanded opportunity.
“NASA is full of brilliant people, and it can be challenging to present alternatives. But through clear communication and data-driven recommendations, we find solutions that work,” Henspeter said.

As she looks to the Artemis Generation, Henspeter hopes to pass along a deep respect for teamwork and shared purpose.
“Every contribution matters. Whether it seems big or small, it makes a difference in achieving our mission,” she said. “I take pride in my role and in being part of the NASA team.”

Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side near the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Intuitive Machines NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) mission was designed to demonstrate technologies to help scientists better understand lunar resources ahead of crewed Artemis missions to the Moon. During the short-lived mission on the Moon, the performance of PRIME-1’s technology gave NASA teams reason to celebrate.
“The PRIME-1 mission proved that our hardware works in the harshest environment we’ve ever tested it in,” said Janine Captain, PRIME-1 co-principal investigator and research chemist at NASA’s Kennedy Space Center in Florida. “While it may not have gone exactly to plan, this is a huge step forward as we prepare to send astronauts back to the Moon and build a sustainable future there.”
Intuitive Machines’ IM-2 mission launched to the Moon on Feb. 26, 2025, from NASA Kennedy’s Launch Complex 39A, as part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. The IM-2 Nova-C lunar lander, named Athena, carried PRIME-1 and its suite of two instruments: a drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), designed to bring lunar soil to the surface; and a mass spectrometer, Mass Spectrometer Observing Lunar Operations (MSOLO), to study TRIDENT’s drill cuttings for the presence of gases that could one day help provide propellant or breathable oxygen to future Artemis explorers.
The IM-2 mission touched down on the lunar surface on March 6, just around 1,300 feet (400 meters) from its intended landing site of Mons Mouton, a lunar plateau near the Moon’s South Pole. The Athena lander was resting on its side inside a crater preventing it from recharging its solar cells, resulting in an end of the mission.
“We were supposed to have 10 days of operation on the Moon, and what we got was closer to 10 hours,” said Julie Kleinhenz, NASA’s lead systems engineer for PRIME-1, as well as the in-situ resource utilization system capability lead deputy for the agency. “It was 10 hours more than most people get so I am thrilled to have been a part of it.”
Kleinhenz has spent nearly 20 years working on how to use lunar resources for sustained operations. In-situ resource utilization harnesses local natural resources at mission destinations. This enables fewer launches and resupply missions and significantly reduces the mass, cost, and risk of space exploration. With NASA poised to send humans back to the Moon and on to Mars, generating products for life support, propellants, construction, and energy from local materials will become increasingly important to future mission success.
“In-situ resource utilization is the key to unlocking long-term exploration, and PRIME-1 is helping us lay this foundation for future travelers.” Captain said.
The PRIME-1 technology also set out to answer questions about the properties of lunar regolith, such as soil strength. This data could help inform the design of in-situ resource utilization systems that would use local resources to create everything from landing pads to rocket fuel during Artemis and later missions.
“Once we got to the lunar surface, TRIDENT and MSOLO both started right up, and performed perfectly. From a technology demonstrations standpoint, 100% of the instruments worked.” Kleinhenz said.
The lightweight, low-power augering drill built by Honeybee Robotics, known as TRIDENT, is 1 meter long and features rotary and percussive actuators that convert energy into the force needed to drill. The drill was designed to stop at any depth as commanded from the ground and deposit its sample on the surface for analysis by MSOLO, a commercial off-the-shelf mass spectrometer modified by engineers and technicians at NASA Kennedy to withstand the harsh lunar environment. Designed to measure the composition of gases in the vicinity of the lunar lander, both from the lander and from the ambient exosphere, MSOLO can help NASA analyze the chemical makeup of the lunar soil and study water on the surface of the Moon.
Once on the Moon, the actuators on the drill performed as designed, completing multiple stages of movement necessary to drill into the lunar surface. Prompted by commands from technicians on Earth, the auger rotated, the drill extended to its full range, the percussion system performed a hammering motion, and the PRIME-1 team turned on an embedded core heater in the drill and used internal thermal sensors to monitor the temperature change.
While MSOLO was able to perform several scans to detect gases, researchers believe from the initial data that the gases detected were all anthropogenic, or human in origin, such as gases vented from spacecraft propellants and traces of Earth water. Data from PRIME-1 accounted for some of the approximately 7.5 gigabytes of data collected during the IM-2 mission, and researchers will continue to analyze the data in the coming months and publish the results.

The Mass Spectrometer Observing Lunar Operations (MSolo) for NASA’s Volatile Investigating Polar Exploration Rover (VIPER) mission is prepared for packing inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface.NASA/Kim Shiflett A NASA-developed technology that recently proved its capabilities in the harsh environment of space will soon head back to the Moon to search for gases trapped under the lunar surface thanks to a new Cooperative Research and Development Agreement between NASA and commercial company Magna Petra Corp.
The Mass Spectrometer Observing Lunar Operations (MSOLO) successfully demonstrated the full range of its hardware in lunar conditions during the Intuitive Machines 2 mission earlier this year. Under the new agreement, a second MSOLO, mounted on a commercial rover, will launch to the Moon no earlier than 2026. Once on the lunar surface, it will measure low molecular weight volatiles in hopes of inferring the presence of rare isotopes, such as Helium-3, which is theorized to exist, trapped in the regolith, or lunar dust, of the Moon.
“This new mission opportunity will help us determine what volatiles are present in the lunar surface, while also providing scientific insight for Magna Petra’s goals,” said Roberto Aguilar Ayala, research physicist at NASA’s Kennedy Space Center in Florida. “Learning more about the lunar volatiles and their isotopes supports NASA’s goal of sustaining long-term human space exploration. We will need to extract resources locally to enhance the capabilities of our astronauts to further exploration opportunities on the lunar surface.”
The MSOLO instrument will be integrated on a commercial rover, selected by Magna Petra. The rover will allow MSOLO to gather the data needed for researchers to understand which low-molecular weight gases reside within the Moon’s surface.
NASA will work with the partner to integrate MSOLO so that it will function properly with the rover, and the partner will analyze and share data in real time with NASA to understand the location of these volatiles on the Moon and their ability to be extracted in the future.
Magna Petra hopes to understand the presence of Helium-3 isotope within the Moon’s surface, with the ultimate goal of collecting it and bringing it back to Earth for use in a variety of industries, including energy production through nuclear fusion, quantum computing, health care, and specialized laboratory equipment.
The MSOLO instrument began as a commercial off-the-shelf mass spectrometer designed to analyze volatiles used in the manufacturing of semi-conductors, which helped keep NASA’s development costs down. NASA modified the device to withstand the rigors of spaceflight and the Moon’s harsh conditions. On its first journey to the Moon, MSOLO was part of the Polar Resources Ice Mining Experiment 1.
Signed on April 2, the reimbursable agreement is the first of its kind established at NASA Kennedy. Under the agreement, Magna Petra will reimburse NASA for costs such as supporting MSOLO integration and testing with the rover, pre-mission preparation and mission operations of the instruments, and expertise in system engineering, avionics, and software.
“This innovative agreement promises to provide valuable data to both partners,” said Jonathan Baker, chief of Spaceport Development at NASA Kennedy. “This approach demonstrates NASA’s commitment to finding unique ways to work with commercial industry to help advance technology in a fiscally responsible way and enabling innovation for the benefit of humankind.”
Throughout the mission, NASA will retain ownership of MSOLO. Once the mission is complete, the instrument will no longer have access to power and communications and will remain on the surface of the Moon. The valuable data gathered during the mission will be submitted to the Planetary Data System for public dissemination.
