NASA’s Apollo Samples, LRO Help Scientists Forecast Moonquakes

NASA’s Apollo Samples, LRO Help Scientists Forecast Moonquakes This mosaic of the Taurus-Littrow valley was made using images from the Narrow Angle Cameras onboard NASA’s Lunar Reconnaissance Orbiter. The orbiter has been circling and studying the Moon since 2009. The ancient-lava-filled valley is cut by the Lee-Lincoln thrust fault, visible as a sinuous, white line extending from South Massif (mountain in the bottom left corner) to North Massif (mountain in the top center) where the fault abruptly changes direction and cuts along the slope of North Massif. The Lee-Lincoln fault has been the source of multiple strong moonquakes causing landslides and boulder falls on both North and South massifs. The approximate location of the Apollo 17 landing site is indicated to the right of the fault with a white “x”. NASA/ASU/SmithsonianAs NASA prepares to send astronauts to the surface of the Moon’s south polar region for the first time ever during the Artemis III mission, scientists are working on methods to determine the frequency of moonquakes along active faults there.
Faults are cracks in the Moon’s crust that indicate that the Moon is slowly shrinking as its interior cools over time. The contraction from shrinking causes the faults to move suddenly, which generates quakes. Between 1969 and 1977, a network of seismometers deployed by Apollo astronauts on the Moon’s surface recorded thousands of vibrations from moonquakes.
Moonquakes are rare, with the most powerful ones, about magnitude 5.0, occurring near the surface. These types of quakes are much weaker than powerful quakes on Earth (magnitude 7.0 or higher), posing little risk to astronauts during a mission lasting just a few days. But their effects on longer-term lunar surface assets could be significant. Unlike an earthquake that lasts for tens of seconds to minutes, a moonquake can last for hours, enough time to damage or tip over structures, destabilize launch vehicles on the surface, or interrupt surface operations.
“The hazard probability goes way up depending on how close your infrastructure is to an active fault,” said Thomas Watters, senior scientist emeritus at the Smithsonian’s National Air & Space Museum in Washington.
Watters is a long-time researcher of lunar geology and a co-investigator on NASA’s LRO (Lunar Reconnaissance Orbiter) camera. Recently, he and Nicholas Schmerr, a planetary seismologist at the University of Maryland in College Park, developed a new method for estimating the magnitude of seismic shaking by analyzing evidence of dislodged boulders and landslides in an area, as the scientists reported on July 30 in the journal Science Advances. Studies like these can help NASA plan lunar surface assets in safer locations.
Unlike an earthquake that lasts for tens of seconds to minutes, a moonquake can last for hours, enough time to damage or tip over structures, destabilize launch vehicles on the surface, or interrupt surface operations.
There are thousands of faults across the Moon that may still be active and producing quakes. Watters and his team have identified these faults by analyzing data from LRO, which has been circling the Moon since 2009, mapping the surface and taking pictures, providing unprecedented detail of features like faults, boulders, and landslides.
For this study, Watters and Schmerr chose to analyze surface changes from quakes generated by the Lee-Lincoln fault in the Taurus-Littrow valley. NASA’s Apollo 17 astronauts, who landed about 4 miles west of the fault on Dec. 11, 1972, explored the area around the fault during their mission.
By studying boulder falls and a landslide likely dislodged by ground shaking near Lee Lincoln, Watters and Schmerr estimated that a magnitude 3.0 moonquake — similar to a relatively minor earthquake — occurs along the Lee Lincoln fault about every 5.6 million years.
“One of the things we’re learning from the Lee-Lincoln fault is that many similar faults have likely had multiple quakes spread out over millions of years,” Schmerr said. “This means that they are potentially still active today and may keep generating more moonquakes in the future.”
The authors chose to study the Lee-Lincoln fault because it offered a unique advantage: Apollo 17 astronauts brought back samples of boulders from the area. By studying these samples in labs, scientists were able to measure changes in the boulders’ chemistry caused by exposure to cosmic radiation over time (the boulder surface is freshly exposed after breaking off a larger rock that would have otherwise shielded it).
This cosmic radiation exposure information helped the researchers determine how long the boulders had been sitting in their current locations, which in turn helped inform the estimate of possible timing and frequency of quakes along the Lee-Lincoln fault.
This 1972 image shows Apollo 17 astronaut Harrison H. Schmitt sampling a boulder at the base of North Massif in the Taurus-Littrow valley on the Moon. This large boulder is believed to have been dislodged by a strong moonquake that occurred about 28.5 million years ago. The source of the quake was likely a seismic event along the Lee-Lincoln fault. The picture was taken by astronaut Eugene A. Cernan, Apollo 17 commander. NASA/JSC/ASUApollo 17 astronauts investigated the boulders at the bases of two mountains in the valley. The tracks left behind indicated that the boulders may have rolled downhill after being shaken loose during a moonquake on the fault. Using the size of each boulder, Watters and Schmerr estimated how hard the ground shaking would have been and the magnitude of the quake that would have caused the boulders to break free.
The team also estimated the seismic shaking and quake magnitude that would be needed to trigger the large landslide that sent material rushing across the valley floor, suggesting that this incident caused the rupture event that formed the Lee-Lincoln fault.

Taking all these factors into account, Watters and Schmerr estimated that the chances that a quake would have shaken the Taurus-Littrow valley on any given day while the Apollo 17 astronauts were there are 1 in 20 million, the authors noted.
Their findings from the Lee-Lincoln fault are just the beginning. Watters and Schmerr now plan to use their new technique to analyze quake frequency at faults in the Moon’s south polar region, where NASA plans to explore.
NASA also is planning to send more seismometers to the Moon. First, the Farside Seismic Suite will deliver two sensitive seismometers to Schrödinger basin on the far side of the Moon onboard a lunar lander as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. Additionally, NASA is developing a payload, called the Lunar Environment Monitoring Station, for potential flight on NASA’s Artemis III mission to the South Pole region. Co-led by Schmerr, the payload will assess seismic risks for future human and robotic missions to the region.

NASA’s Inventions and Contributions Board (ICB) has awarded Commercial Invention of the Year to NASA Glenn Research Center’s GRX-810: A 3D Printable Alloy Designed for Extreme Environments.
NASA Alloy GRX–810, an oxide dispersion strengthened (ODS) alloy, can endure temperatures over 2,000 degrees Fahrenheit. It is more malleable and can survive more than 1,000 times longer than existing state-of-the-art alloys. This new alloy can be used to build aerospace parts for high-temperature applications, like those inside aircraft and rocket engines, because ODS alloys can withstand harsher conditions before reaching their breaking point.
The NASA Glenn team of inventors includes Dr. Timothy Smith (co-lead), Dr. Christopher Kantzos (co-lead), Robert Carter, and Dr. Michael Kulis.
Four American companies have been granted co-exclusive licenses to produce and market GRX-810 material. All four have replicated NASA Glenn’s patented process and are selling fully coated materials. This benefits the United States economy as a return on investment of taxpayer dollars.

Preparations for Next Moonwalk Simulations Underway (and Underwater) The Research Aircraft for electric Vertical takeoff and landing Enabling techNologies Subscale Wind Tunnel and Flight Test undergoes a free flight test on the City Environment Range Testing for Autonomous Integrated Navigation range at NASA’s Langley Research Center in Hampton, Virginia on April 22, 2025.NASA/Rob LorkiewiczFlying the friendly skies may one day include time-saving trips in air taxis to get from point A to point B – and NASA researchers are currently working to make that future a reality.
They are using wind tunnel and flight tests to gather data on an electric Vertical takeoff and landing (eVTOL) scaled-down small aircraft that resembles an air taxi that aircraft manufacturers can use for their own designs.
As air taxis take to the skies, engineers need real-world data on air taxi designs to better understand flight dynamics and design better flight control systems. These systems help stabilize and guide the motion of an aircraft while in flight, making sure it flies safely in various conditions.
Currently, most companies developing air taxis keep the information about how their aircraft behaves internal, so NASA is using this small aircraft to produce public, non-proprietary data available to all.
“NASA’s ability to perform high-risk flight research for increasingly automated and autonomous aircraft is really important,” said Siena Whiteside, who leads the Research Aircraft for eVTOL Enabling techNologies (RAVEN) project. “As we investigate these types of vehicles, we need to be able push the aircraft to its limits and understand what happens when an unforeseen event occurs…”
For example, Whiteside said, “…when a motor stops working. NASA is willing to take that risk and publish the data so that everyone can benefit from it.”

The small aircraft weighs 38 pounds with a wingspan of six feet and has 24 independently moving components.
Each component, called a “control effector,” can move during flight to change the aircraft’s motion – making it an ideal aircraft for advanced flight controls and autonomous flight research.
The testing is ongoing at NASA’s Langley Research Center in Hampton, Virginia.
Researchers first used the center’s 12-Foot Low-Speed Tunnel in 2024 and have since moved on to flight testing the small aircraft, piloting it remotely from the ground. During initial flight tests, the aircraft flew while tied to a tether. Now, the team performs free flights.
Lessons learned from the aircraft’s behavior in the wind tunnel helped to reduce risks during flight tests. In the wind tunnel, researchers performed tests that closely mirror the motion of real flight.
While the scale aircraft was in motion, researchers collected information about its flight characteristics, greatly accelerating the time from design to flight.
The team also could refine the aircraft’s computer control code in real time and upload software changes to it in under 5 minutes, saving them weeks and increasing the amount of data collected.

Bowman Partners in ResearchNASA developed the custom flight controls software for RAVEN SWFT using tools from the company MathWorks.
NASA and MathWorks are partners under a Space Act Agreement to accelerate the design and testing of flight control approaches on RAVEN SWFT, which can apply to future novel aircraft.
The work has allowed NASA’s researchers to develop new methods to reduce the time for an aircraft to achieve its first flight and become a finished product.
RAVEN SWFT serves as a steppingstone to support the development of a potential larger, 1,000 pound-class RAVEN aircraft that will resemble an air taxi.
This larger RAVEN aircraft is being designed in collaboration with Georgia Institute of Technology and also would serve as an acoustical research tool, helping engineers understand the noise air taxi-like aircraft create.
The larger aircraft would allow NASA to continue to collect data and share it openly.
By performing flight research and making its data publicly available, NASA aims to advance U.S. leadership in technology development for safe, quiet, and affordable advanced air mobility operations.

Compton J. Tucker Retires from NASA and is Named NAS Fellow
Dr. Compton J. Tucker – a senior researcher at NASA’s Goddard Space Flight Center (GSFC) – joins 149 newly elected members to the National Academy of Sciences (NAS) – see Photo. NAS is one of the highest honors in American science. Compton gave a virtual presentation at GSFC on July 21, 2025, in which he showed highlights from his 50 years of research and reflected on the honor of being selected as an NAS fellow. He admitted that he was surprised upon learning of his election in April 2025 – despite his prestigious career.

He first came to GSFC as a NAS postdoc in 1975 after having earned his Bachelor’s of Science degree at Colorado State University (CSU) in 1969. He followed with his Master’s of Science degree and Ph.D. from CSU’s College of Forestry in 1973 and 1975 respectively. Two years later, he joined NASA as a civil servant. After a prestigious 48 years of public service, Compton has decided to retire in March 2025.
Compton is a well-known pioneer in the field of satellite-based environmental analysis, using data from various U.S. Geological Survey–NASA Landsat missions and from the National Oceanographic and Atmospheric Administration’s (NOAA) Advanced Very High Resolution Radiometer (AVHRR) instrument, the prototype of which launched aboard the Television Infrared Observation Satellite–N (TIROS-N) in 1978, with launches continuing on NOAA and European polar orbiting satellites throughout the next 40 years. The last two AVHRR instruments, which launched on the European Organisation for the Exploitation of Meteorological Satellites’ (EUMETSAT) Meteorological Operational satellites (METOP–B and -C) in 2012 and 2018 respectively, are still operational today.
Photo 2. Earth scientist Compton Tucker, who has studied remote sensing of vegetation at NASA Goddard for 50 years, has been elected to the National Academy of Sciences.Photo credit: Compton TuckerIn his GSFC presentation, Compton described how, in the course of doing their research, he and his colleague(s) realized the original plans for AVHRR resulted in Channel 1 and 2 overlapping one another. In short, he explained that his input helped persuade NOAA management to change the design for Channel 1 of AVHRR – beginning with NOAA-7. It is fair to say that this change had a lasting impact, with 16 more AVHRR instruments (with slight modifications over time) launched over the next four decades.
Compton’s research has focused on global photosynthesis on land (e.g., grass-dominated savannas), determined land cover (i.e., forest fragmentation, deforestation, and forest condition), monitored droughts and food security, and evaluated ecologically coupled disease outbreaks. From 2005 to 2010, he was the co-chair of two Interagency Working Groups for Observations and Land Use and Land Cover Change. Compton was active in NASA’s Space Archaeology Program, participating in ground-based radar and magnetic surveys in Turkey, particularly at Troy, the Granicus River Valley, and Gordion. Over the course of his 50-year career, he has authored or co-authored more than 400 scholarly articles that have appeared in scientific journals – and in his presentation he hinted that more might be in store after retirement.
Compton has received numerous scientific awards and honors. He was elected to a fellow of the American Geophysical Union in 2009 and to the American Association for the Advancement of Science in 2015. He received the Senior Executive Service Presidential Rank Award for Meritorious Service (2017), the Vega Medal from the Swedish Society of Anthropology and Geography (2014), the Galathea Medal from the Royal Danish Geographical Society (2004), the William T. Pecora Award from the U.S. Geological Survey (1997), the Michael Collins Trophy for Current Achievement from the National Air and Space Museum (1993), the Henry Shaw Medal from the Missouri Botanical Garden (1992), and the Exceptional Scientific Achievement Medal from NASA (1987).
Compton enjoyed sharing his knowledge with the next generation of scientists. He served as an adjunct professor at the University of Maryland (1994–2024) and a consulting scholar at the University of Pennsylvania Museum of Archeology and Anthropology (2005–2024).
Congratulations to Compton on earning this prestigious – and well-earned – recognition from NAS. Best wishes to him in whatever is next on his journey.
The National Academy of Sciences is a private, nonprofit institution that was established under a congressional charter signed by President Abraham Lincoln in 1863. It recognizes achievement in science by election to membership, and – with the National Academy of Engineering and the National Academy of Medicine – provides science, engineering, and health policy advice to the federal government and other organizations.
