Editor’s note: This release was updated Oct. 8, 2026 with the formal name of the summit.
NASA is launching two new science and technology initiatives to deepen scientific understanding and accelerate the innovation that will shape America’s future in space.
The initiatives are announced in conjunction with the White House Office of Science and Technology Policy’s (OSTP) “Science: A Golden Age Summit” in Washington on Thursday with top U.S. agency leaders. The programs reflect NASA’s commitment to pioneering research and transformative technologies and advancing the Trump Administration’s vision as outlined in the July report to the President, Science: A New Golden Age. One focuses on peer review and the other on fellowship researchers.
“NASA has a proud history of pursuing bold ideas and achieving the near impossible,” said NASA Administrator Jared Isaacman. “Under President Trump’s leadership, we are building on that legacy by creating new opportunities for great science, experimenting with how we evaluate and accelerate the best ideas, and investing in the next generation of researchers through the Genesis Mission Fellowships. We are entering a new Golden Age of American innovation and discovery, and NASA will be at the forefront.”
During a fireside chat, Isaacman and Michael Kratsios, assistant to the President for science and technology and director of OSTP, will discuss the following:
Establishing a coordinated metascience initiative within NASA’s Science Mission Directorate to strengthen the reliability, efficiency, transparency, and overall productivity of the agency’s scientific practices. As part of this effort, NASA is expanding the agency’s use of dual anonymous peer review to ensure proposals are evaluated solely on their intrinsic scientific merit. This approach enhances fairness and supports innovative and unconventional research ideas. Started as a pilot program during the first Trump Administration, this initiative has helped position NASA as a leader in advancing best practices in scientific review.
NASA will support 10 Genesis Mission Fellows, who are accelerated doctoral students with dual competencies in super intelligence (SI) and science or engineering. Fellows will work directly on NASA mission areas and conduct research at NASA laboratories, advancing SI-enabled scientific discovery. The fellowships will be based on NASA’s successful Future Investigators in NASA Earth and Space Science and Technology program.
NASA leads the nation in space exploration, scientific discovery, and technological innovation. Through these new initiatives, NASA will continue to inspire the world and drive progress in science and technology.
Through ROSES-25 A.14 Atmosphere NASA is soliciting proposals for data analysis and modeling of NASA supported airborne campaign data. NASA’s Earth Science Division has supported numerous airborne campaigns during the last few years, see Section 2 of the program element text.
A.14 Atmosphere required a mandatory Notice of Intent (NOI) to propose. Proposers who have not already submitted a compliant NOI are not eligible to submit a proposal.
ROSES-2025 Amendment 74 delays the due date for A.14 Atmosphere to December 2, 2026. Also, Section 4.3.3 “Use of Generative AI” now mentions a related NSPIRES cover page question on the use of AI. An updated FAQ has been posted under “Other Documents” on the NSPIRES page for this program element.

It started as a routine data-quality check. But as Robert Wagner, a scientist with NASA’s Lunar Reconnaissance Orbiter (LRO), scanned a giant Moon map on his computer screen, an unusually large bright spot circled by a dark halo caught his eye, as it implied that surface material in that area had been shaken up.
“I just stopped, dropped everything, and started looking into what that spot was,” said Wagner, an image-processing specialist from Intuitive Machines who works with data from the Lunar Reconnaissance Orbiter Camera (LROC) system.
By comparing before and after images of the Moon, Wagner realized he had discovered the largest, newly formed crater ever found in the solar system, as scientists reported Wednesday in Science Advances. This discovery highlights the value of NASA’s Moon orbiter data in studying a dynamic landscape as the agency advances a sustained human presence and expanded scientific and commercial activity on the Moon.

The white spot is not the crater itself, but rather material flung out of the crater, which formed when a rock, possibly this size of a three- to six‑story building, crashed into the Moon between April 11 and May 22, 2024 – a once-in-a-century event, as scientists reported on Sept. 15, 2026, in a pair of papers in Science Advances. The area shown in the images is 38 miles wide.

Officially named McGetchin after pioneering lunar scientist Tom McGetchin, the crater formed on the Moon’s eastern edge sometime between April 11 and May 22, 2024, after a comet or asteroid the size of a three- to six-story building hit the surface.
The crash left a crater, 728 feet wide, that spans the length of two football fields. And at 141 feet deep, the crater could fit three vertically stacked yellow school buses.
Scientists estimate that an impact of this magnitude happens on the Moon about once in a century or even longer.
Moon takes some hits
For more than 17 years, LRO has been circling the Moon and using its seven instruments to map the topography, surface composition, temperature, and radiation environment there. The spacecraft’s team has identified at least 1,000 new impact craters throughout the mission and flagged 100,000 more surface changes from an object smashing into the Moon or from the debris that flung out after.
With no atmosphere to slow them or burn them up, space rocks and other objects easily reach the lunar surface. Most are much smaller compared to the object that carved out McGetchin crater. The smallest craters scientists can distinguish from LRO images are about 30 feet wide, the length of a three-story building laid on its side, made by rocks about 43 inches wide, the size of a monster-truck tire. Scientists estimate that impacts of this scale produce about 140 new craters across the Moon each year. But most new ones are made by microscopic projectiles that leave holes too small to identify in orbital images.
With its numerous instruments, the spacecraft can observe changes to the lunar surface that aren’t apparent in the LROC images alone. After the crater was discovered, scientists working with LRO’s thermal instrument, Diviner, made follow-up observations of the site. They found a 4-mile-wide area around the crater that is about 16 degrees Fahrenheit cooler at night than its surroundings.
This animated image set shows an area on the eastern limb of the Moon before and after McGetchin crater formed there sometime between April 11 and May 22, 2024. The post-impact image was constructed using data taken by NASA’s Lunar Reconnaissance Orbiter (LRO) thermal instrument, Diviner, between Nov. 15, 2025, and Feb. 18, 2026, after scientists discovered the crater in visible-light images taken by LRO’s Wide-Angle Camera. Pre-impact temperatures are from the Diviner Global High-Resolution Mosaics (GHRM). The crater formed on the Moon after a comet or asteroid, possibly the size of a six-story building, hit the surface in a rare, once-in-a-century collision. The dark blue strip that flashes into view reveals a 4-mile-wide “cold spot” around the crater that is about 16 degrees Fahrenheit cooler at night than its surroundings. This cooling happens because an impact fluffs up regolith around a crater, making it less dense and therefore less able to retain heat. Scientists on the Diviner team reported this finding in a paper published on Sept. 16, 2026, in Science Advances. The red and yellow spots indicate areas typically associated with rocks excavated by long-ago impacts which, though still at cryogenic temperatures like their surroundings, remain slightly warmer at night.

Reporting in a second paper Wednesday in the same journal, researchers say that the cooling happens because the impact fluffs up the regolith around the crater, making it less dense and therefore less able to retain heat.
The large extent of this “cold spot” is striking, scientists say, because it shows that impacts can modify the Moon’s surface far beyond the crater itself. These physical changes could affect how rover wheels interact with the surface, for instance.

Robert Wagner, image processing specialist for LRO, made this map using two sets of mages taken several years apart. He used a software designed to highlight any changes between the two sets. Anything that stayed the same turned gray; anything different showed up as bright or dark patches. A black arrow just left of center points to McGetchin crater.

Road to discovery
The LROC system collects images from about 60 miles above the Moon as LRO loops from pole to pole. The system includes two cameras that capture high‑resolution black‑and‑white images and one camera for moderate‑resolution multispectral images. Over the years and thousands of passes, scientists have built maps detailed enough to spot not only new craters, but also landslides, landers, seismic faults, and even hints of lava tubes.
LROC scientists regularly analyze close-up images of small portions of the Moon’s surface taken by the Narrow-Angle Camera. Using these images, they look for changes that are typically less than 30 feet across. But every few years the team searches for large (wider than 150 feet) features by creating global Moon maps and comparing them to older versions.
An overhead, close-up view of McGetchin crater that was taken on Dec. 5, 2025, by NASA’s Lunar Reconnaissance Orbiter (LRO) Narrow-Angle Camera (NAC). After the crater was discovered on Oct. 24, 2025, in global images from LRO’s Wide-Angle Camera, which captures broad views with pixels the size of American football fields, scientists turned to the NAC, which takes much sharper views at about 3 feet per pixel. The NAC images, taken as LRO flew over the impact site again, revealed the crater size, shape, and how the surrounding terrain was affected by the impact that carved McGetchin. The image covers an area that’s ¾ mile wide.

This view from the side (55° away from straight down) towards the east, covers an area of the Moon that’s about 1.5 miles wide. It was taken by NASA’s Lunar Reconnaissance Orbiter Narrow-Angle Camera on March 3, 2026.
NASA Goddard/Intuitive Machines
That’s what Wagner was doing on Oct. 24, 2025, when he came across McGetchin. Using images from LROC’s Wide-Angle Camera, which captures broad views with pixels the size of football fields, he stacked hundreds of “before” and “after” frames with software designed to highlight change. Anything that stayed the same turned gray while anything different showed up as bright or dark patches.
While the process sounds straightforward, spotting real craters requires a lot of manual work. The software flags every tiny shift in lighting or shadow, generating hundreds of false alarms. For this reason, Wagner typically verifies the software, looking for small fuzzy halos around pixel‑wide bright points, which indicate splashes of regolith around a new crater.
Spanning hundreds of pixels, McGetchin stood out immediately. “It was by far the most obvious impact debris pattern I’ve ever seen in one of these images,” Wagner said.
After his discovery, scientists turned to the Narrow-Angle Camera, which takes much sharper views at about 3 feet per pixel. This camera’s close-up images, taken as LRO flew over the impact site again, revealed the crater size, shape, and how the surrounding terrain was affected. These images also helped researchers estimate the size and force of the rock fragment that formed the new crater, details that are expected to appear in a future paper.

This is the view that Robert Wagner saw on Oct. 24, 2025, during a routine data-quality check. Wagner is an image processing specialist for NASA’s Lunar Reconnaissance Orbiter Camera, a system of three cameras. Using images from the Wide-Angle Camera (WAC), which captures broad views with pixels the size of American football fields, he stacked hundreds of images captured by WAC over the last several years with software designed to highlight change. Anything that stayed the same is gray; anything that changed showed up as bright or dark patches. The stripes in the image are due to slight changes in lighting between the older and newer images. This image composite shows an area of the Moon approximately 900 miles across.

NASA has selected 12 new investigations to help support human explorers in space. Six will help advance the ability to produce food off-planet, while another six advance the understanding of how unique conditions associated with space exploration can impact the health and physiology of astronauts.
The six food-focused investigations, supported by the agency’s Space Crops grants, advance NASA’s goal of harnessing the power of plants to enhance quality of life for humans in space, as well as to enable lunar and Mars exploration. Four of the space crops proposals focus on studies of edible plants and how their growth, physiology, and associated microbial communities are affected by environmental conditions in space or on other planetary bodies.
Another proposal involves understanding mechanisms by which certain plant species, called resurrection plants, can withstand extreme, dry conditions. The last space crops proposal builds on previous studies on the International Space Station to uncover functions of algal genes, segments of DNA controlling algae survival, whose expression is modified by spaceflight. Such studies can help scientists integrate biological-based solutions into space life-support systems.
The second set of six proposals fall under the agency’s Biological and Physical Sciences Division’s focus on precision health, which seeks to unravel the mechanisms by which space exploration affects health and well-being. One proposal studies how lunar dust exposure impacts respiratory, immune, and inflammation responses. A second proposal identifies repurposed drugs that can mitigate the effects space travel has on health and physiology.
Two more of the research proposals look at how radiation combined with other stressors affects age-relevant characteristics seen in various organ and physiological systems. The final two proposals assess molecular and cellular changes induced by stressors in space that can alter gene expression or protein function. The research will identify ways to mitigate health issues and develop early-warning detection systems to notify crew of potential concerns.
The principal investigators who conduct the space biology studies come from 10 institutions across eight states. Nine of the awards are for investigators who are receiving funding from the Space Biology Program for the first time.

Studying biological and physical phenomenon under extreme conditions allows researchers to advance the fundamental scientific knowledge required to go farther and stay longer in space, while also benefitting life on Earth.
The fully-integrated LEMS (Lunar Environment Monitoring Station) ready for environmental testing. A small suitcase-size instrument suite built at NASA Goddard, LEMS is designed to carry out continuous, long-term monitoring of the seismic environment at the Moon, including surface motion caused by moonquakes and meteorite impacts in the lunar south polar region.

NASA has declared “wrenches down” on the first completed payload designed for Artemis astronauts to deploy on the Moon’s surface. Engineers working on NASA’s Lunar Environment Monitoring Station, or LEMS, have completed hardware development and testing and the payload is ready for its permanent home near the lunar South Pole. With the hardware complete, LEMS is ready to support one of the Artemis program’s core goals: enabling sustained lunar science and exploration.
The LEMS instrument package contains two highly sensitive seismometers that will monitor ground vibrations from moonquakes and meteorite impacts, providing scientists with insights into the Moon’s interior and the seismic hazards astronauts might encounter at the surface. Its modular design allows the system to be adapted or expanded to host new instruments in the future, creating a reusable platform that can evolve as scientific priorities grow.
The payload will remain in a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where it was built, until it is assigned to an Artemis mission for deployment to the lunar surface.
“The completion of the LEMS scientific instrument is a major step in a new era of lunar surface science. Innovative science experiments will uncover, measure, and reveal the Moon’s secrets while astronauts open new frontiers for discovery,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “And, behind the scenes, countless teams across NASA and our partners are pushing the boundaries of what surface instruments can do, building the tools that will make future exploration possible and safer.”
A scientist wearing NASA’s xEMU prototype space suit is testing the handling of a mockup version of NASA’s Lunar Environment Monitoring Station, or LEMS. The testing took place at the Active Response Gravity Offload System, a simulated reduced gravity environment at NASA’s Johnson Space Center in Houston.

The LEMS payload builds on a legacy of lunar seismic tracking. Apollo astronauts deployed a network of seismometers on the Moon’s nearside equatorial region between 1969 and 1972. Those instruments operated until 1977, recording about 13,000 moonquakes and other ground vibrations that helped scientists begin to understand the composition of the Moon’s interior. For decades, researchers have hoped to spread more seismometers, updated with new technologies, across the lunar surface.
Now, LEMS will carry the first seismometers to be deployed by future astronauts to listen for faint ground vibrations, collecting new clues to the Moon’s internal structure and ongoing seismic activity. The sensors will be the most compact, sensitive, and energy-efficient seismometers ever built for planetary exploration.
LEMS itself is about the size of a small suitcase, weighing 11 pounds in the Moon’s low-gravity environment. It will carry not just these seismic sensors, but everything it needs to function independently of humans after deployment. LEMS is built to manage its own power production via a lightweight, flexible solar array that conforms to the shape of the LEMS unit. It also will manage its operational activities to ensure continuous data collection based on a preset plan, and monthly data transmission to Earth. The payload will do all this while maintaining a stable internal temperature throughout the massive day-to-night temperature swings of the South Pole region.

LEMS is a compact, autonomous, and self-sustaining seismometer suite designed to carry out continuous, long-term monitoring of the lunar seismic environment at the South Polar region.

“When we conceived of LEMS, we weren’t just thinking about the next mission, we were thinking about the next generation of lunar exploration,” said Mehdi Benna, a University of Maryland Baltimore County scientist who leads LEMS from NASA Goddard. “Our vision was to create a scientific buoy for the Moon. Like an ocean buoy on Earth, LEMS is designed to be easy to build, adaptable to different scientific objectives, and capable of operating independently for years.”
Before any surface science could happen, Benna and his team had to ensure that LEMS could survive the trip to the Moon and the harsh environment of its surface. Over the past five months, LEMS and its components have been subjected to a demanding series of environmental and operational tests. Engineers verified LEMS can endure the violent shaking of launch, the journey to the lunar surface, and the Moon’s temperature and radiation environment. The team also showed that the instrument package’s mechanical and electrical design is safe for astronaut handling.
The LEMS payload was built to operate through the lunar night, which lasts two Earth weeks, without external power assistance or a heat source. Past lunar surface instruments relied on radioisotope heaters for warmth and power. But LEMS instead will withstand temperatures that dip to minus 400 degrees Fahrenheit in some areas by using advanced insulation materials, low-thermal-conductivity cables that minimize heat loss, and a thermal regulator that conducts heat away during the day to prevent overheating and helps retain heat at night.
These innovations reduce mass and power needs, setting the stage for lighter, energy-efficient instruments that can operate continuously at future Artemis landing sites and the NASA-led Moon Base.
The LEMS payload is led by University of Maryland Baltimore County and University of Maryland College Park. Technical implementation is led by NASA Goddard. The University of Arizona, in partnership with Silicon Audio, Inc., supplied LEMS’ two state-of-the-art seismometers. Morehead State University in Kentucky provided LEMS’ telecommunication system and will operate the instrument on the surface. Washington University in St. Louis will manage the instrument’s data processing and dissemination to the larger scientific community.
In addition to model development, the Mars Climate Modeling Center (MCMC) conducts cutting-edge scientific research on the past and present atmosphere and climate of Mars.
The Mars Climate Modeling Center (MCMC) conducts atmospheric and climate science research using the NASA Ames Mars Global Climate Models (MGCMs), advancing our understanding of Mars’ climate today, in its ancient past, and as a target for future exploration.
Mars’ climate is governed by three interacting cycles — dust, water, and carbon dioxide (CO₂) — that vary across seasons and from year to year. MCMC scientists use the MGCMs to study these cycles and the processes that drive them, including:
Dust storms and dust transport – Investigating the mechanisms that lift, transport, and remove dust in the Martian atmosphere, including the onset and evolution of regional and global-scale dust storms.
Water and CO₂ cycles – Studying the seasonal exchange of water and CO₂ between the atmosphere, polar caps, and surface, and the clouds that form as a result.
Atmospheric dynamics – Examining circulation patterns, wave-mean flow interactions, and the extension of the MGCM into the middle atmosphere to better connect the lower and upper atmosphere.
Ancient Mars and habitability – Reconstructing past climate states, including the role of asteroid and comet impacts, to assess when and where conditions may have supported liquid water and habitability.
Mission support – Applying model results to landing site selection and characterization, atmospheric entry planning, and interpretation of data from current and past Mars missions.
This research is carried out by a team of civil servant and contractor scientists, postdoctoral researchers, and students, often in collaboration with universities and other NASA centers. You can read more about individual MCMC team members and their science on the Group Members page. A full list of MCMC research papers, conference presentations, and technical reports is available on the Publications page.

On July 3, one of NASA’s two Mars-destined ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft captured photos of Earth and the Moon in visible and thermal infrared light. At the time, the spacecraft was 363,250 miles (584,600 kilometers) from Earth and 115,600 miles (186,100 kilometers) from the Moon, making the Moon appear relatively large.
Taken with the Sun only partly illuminating Earth and the Moon, the visible light image shows the two bodies as crescents, with only around 8% of each face sunlit. Yet in the thermal infrared image, the shadowed hemisphere of Earth is illuminated by its own heat from both the atmosphere and surface, glowing at minus 10 to minus 44 degrees Fahrenheit (250 to 280 kelvins). Without the insulating blankets of oceans and atmospheres, the Moon’s far side remains at a much cooler minus 280 degrees Fahrenheit (100 kelvins).

The ESCAPADE mission used its Visible and Infrared Observation System cameras, provided by Northern Arizona University in Flagstaff, to capture the images, which are more than just road trip photo album snaps.
“We are thrilled that ESCAPADE was able to accommodate these excellent space-qualified cameras which will search for visible Martian aurora and investigate thermal properties of the Martian surface and atmosphere,” said Rob Lillis, the mission’s principal investigator at the University of California, Berkeley. “Since Earth and the Moon are well-known targets, imaging them provides an important calibration check for ESCAPADE’s cameras.”
The ESCAPADE spacecraft, which were built by Rocket Lab, are currently in a “loiter” orbit around Lagrange point 2, a location in space about a million miles from Earth. In November 2026, the spacecraft will fly by Earth to use the planet’s gravity to slingshot their way to Mars. When the spacecraft arrive in September 2027, they will study how a million-mile-per-hour stream of material flowing from the Sun, known as solar wind, interacts with the Martian environment and how that drives atmospheric loss at the Red Planet.

NASA/GSFC
NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth-based auroras.
Results published Thursday in Nature Communications show the same mechanism that circulates and catapults charged particles into Earth’s atmosphere is happening at Mars on much smaller scales because of differences in the two planets’ magnetic fields.
The MAVEN spacecraft, in orbit around Mars, experienced a loss of signal with ground stations on Earth on Dec. 6, 2025. On June 3, NASA declared the mission had concluded after finding the spacecraft to be unrecoverable. However, data from the mission is still being used to inform NASA science and future missions to Mars.
When the Sun’s magnetic field lines get close to Earth’s magnetosphere, the large magnetic bubble protecting the planet, they can reconnect and inject energy and mass throughout Earth’s magnetosphere and magnetotail, ultimately firing electrons back into the atmosphere to generate Earth’s auroras. This process, called the Dungey cycle, drives electrical currents, accelerates charged particles that create auroras, and controls the circulation of plasma in Earth’s magnetosphere and ionosphere.
This new study shows that a miniature version of the Dungey cycle is happening over Mars’ strong crustal magnetic fields, which gives scientists a better look into the physics of Martian auroras.
“We knew that magnetic reconnection was happening at Mars but did not expect it to be like the Dungey cycle,” said Shaosui Xu, lead author of the study and associate research physicist at the Space Sciences Laboratory at the University of California, Berkeley.
Mars does not have a global magnetic field like Earth. Earth’s magnetic field is created by our planet’s churning core, while Mars has numerous miniature magnetospheres that arise from intensely magnetized crust scattered around the planet. These regions were formed around 4 billion years ago when lava cooled in the presence of Mars’ ancient global magnetic field, which has since disappeared due to intense solar wind stripping the planet’s atmosphere.
The MAVEN mission has observed highly localized auroras over these crustal fields, similar to Earth’s auroras at the poles, but it wasn’t until now that scientists could fully understand the physics of how they form. The study used several instruments aboard the MAVEN spacecraft to build up a picture of the Dungey-like behavior: the Magnetometer and Solar Wind Electron Analyzer instruments, which were used to determine the magnetic configuration and derive electrical currents, and the STATIC (Suprathermal and Thermal Ion Composition) instrument, which was used to measure plasma flows in the ionosphere.
“We really pushed the limit of STATIC to get the data we needed,” said Xu. “It was the final piece to the puzzle in understanding these localized auroras.”
The realization that a Dungey-like cycle was happening within these crustal magnetic fields answered the question of how the electrons were being energized to create the auroras. It also shows that a Dungey-like mechanism can happen on both large and small scales, giving more insight into where in the solar system this process could be taking place.
“This is a remarkable result that changes how we think of Martian auroras and is another important step toward understanding why Mars and Earth have evolved so differently despite being governed by the same underlying physics.” said Shannon Curry, MAVEN’s principal investigator and a research scientist at the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder. “I am incredibly proud of our team’s work on this discovery and excited to uncover new insights into the Red Planet and its evolution.”
By finding out more about this process, scientists also are gaining a better understanding of how the solar environment interacts with the Red Planet as a whole, which is essential for future robotic and crewed missions.
“I remember in graduate school discussing with my advisor how the cycling of crustal magnetic fields could work at Mars,” said Xu. “It’s incredible to be part of the team that found the answer to that question.”
The MAVEN mission is part of NASA’s Mars Exploration Program portfolio. The mission’s principal investigator is based at the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder, which also is responsible for managing science operations and public outreach and communications. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the MAVEN mission. Lockheed Martin Space built the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Southern California provides navigation and Deep Space Network support.

NASA selected a mission concept to research how space weather and dynamics within Earth’s atmosphere influence the space environment and help improve prediction capabilities for impacts on crucial technology, such as GPS and low Earth orbit satellites, as well as astronauts in space.
The DAPHNE (Dynamic Atmosphere-Ionosphere Explorer) mission will enter Phase B of development, which includes planning and design for flight and mission operations. It will use identical twin satellites to study how changes in Earth’s lower atmosphere influence our planet’s upper atmosphere, where space weather is manifested.
“NASA is advancing the United States’ leadership as a space weather-ready nation, and by providing new insights into Earth’s atmosphere we can better predict and prepare for impacts in our daily lives on Earth and in space,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “As NASA sends astronauts beyond Earth’s magnetic protection to the Moon, Mars, and beyond, DAPHNE will join the NASA science fleet strategically located across the solar system to provide data that will help mission planners predict and mitigate the effects of space weather for the benefit of all.”
The DAPHNE mission’s low-risk high-return concept will provide coordinated, multi-point measurements of neutral winds, temperature, and composition in the thermosphere. The ionosphere and thermosphere regions are where Earth’s neutral atmosphere transitions into the ionized plasma of space. In this thin shell that surrounds the planet, the atmosphere is in constant motion, shaped by the influence of solar activity and changes in the lower atmosphere and in near-Earth space.
Fundamental observations and physical insights from the DAPHNE mission will incorporate lower-atmospheric energy data to advance space weather predictive capabilities. The mission is led by Aimee Merkel from the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder.
The mission will be subject to a confirmation review in 2027, which will assess the progress of the mission and the availability of funds. If confirmed, the total estimated cost of the mission, excluding launch, will not exceed $250 million in fiscal year 2023 dollars, with a mission launch date of no earlier than 2029.
The DAPHNE mission was proposed as a concept study in response to the DYNAMIC (Dynamical Neutral Atmosphere-Ionosphere Coupling) mission announcement of opportunity. Funding and management oversight for this mission is provided by the Solar Terrestrial Probes program at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history. Formed as fragments coalesced after a violent collision 155 million years ago, the asteroid was transformed by the small but inexorable force of the Sun’s radiation, all while retaining signs of the brief presence of liquid water in its distant past.
Zooming through the main asteroid belt toward one of the Jupiter Trojan asteroid groups, the Lucy spacecraft collected the first close-up images and other data at Donaldjohanson on April 20, 2025, as it passed 650 miles away from the asteroid. The data revealed that, instead of spinning simply around one axis like most other asteroids and planets, Donaldjohanson has a more complicated two-axis rotation. Scientists also saw Donaldjohanson’s peanut shape and the craters and ridges on its surface.
A timelapse video made from images taken by NASA’s Lucy spacecraft as it approached the asteroid Donaldjohanson on April 20, 2025. The L’LORRI (Lucy Long Range Reconnaissance Imager) instrument, the spacecraft’s high-resolution black-and-white imager, collected these images over two hours as the spacecraft rapidly closed in on the asteroid from an initial separation of more than 58,000 miles (93,000 km), until the spacecraft passed a mere 650 miles (1000 km) from the 5-mile- (8 km-) wide asteroid.
NASA/Goddard/SwRI/JHU-APL
Lucy’s encounter with the asteroid was planned as a dress rehearsal for the spacecraft and mission team before its primary asteroid encounters, which begin with Lucy’s flyby of the Trojan asteroid Eurybates on Aug. 12, 2027. The instruments performed as expected, and, as a bonus, scientists got a rare opportunity to study a previously unexplored asteroid up close and to compare it to two asteroids with similar compositions but different histories: Bennu, the target of NASA’s OSIRIS-REx sample-return mission, and Ryugu, the site of JAXA’s (Japan Aerospace Exploration Agency) Hayabusa2 sample-return mission.
With Earth-based telescopes, observers saw fluctuations in the light Donaldjohanson reflects, regular patterns of peaks and valleys, typical of an elongated object rotating once every 10.5 Earth days. But Lucy’s data revealed another pattern: Donaldjohanson appears to be rotating like a wobbly top. Paper authors reported that the asteroid rotates end-over-end once every 10.5 Earth days, and wobbles back and forth around its long axis once every 26.5 days.
The asteroid Donaldjohanson is shown slowly rotating in a tumbling, non-principal axis motion, with its angular momentum vector and rotation axes indicated. The surface is colored by gravity slope, which measures the angle between the local surface and the direction of gravity. Higher values (warmer colors) indicate steeper terrain relative to the local gravitational pull. Regions with limited stereo image coverage have been masked out where the shape model is less well constrained.

Peanut shape
While the Earth-based observations hinted at Donaldjohanson’s elongated shape, the Lucy flyby revealed a “bilobate” structure: two lobes connected by a neck, like a peanut. These lobes are likely two fragments from an asteroid collision that gently came together afterward by their mutual gravity.
Donaldjohanson likely rotated at least 10 times faster when it formed, having slowed to its current rate in the last 20 to 60 million years, the team estimates. As it slowed, the balance between the centrifugal force pushing things apart and gravity pulling things together changed and loose rocky material slid down slopes creating the worn-down appearance of many craters, as the flyby images showed.
The paper’s authors say that the asteroid’s slowing rotation is likely caused by a subtle consequence of solar heating known as the YORP effect. Each part of the asteroid’s Sun-warmed surface radiates heat away as infrared light, and that radiation imparts a tiny recoil force to the surface. Because the asteroid’s shape isn’t symmetric, this results in a net torque, or twist, that can change the asteroid’s rotation. Thus, YORP can slow asteroid spins down or speed them up, as in the case of Bennu (once every four hours) and Ryugu (once about every seven hours), which both likely used to rotate much slower than they do today.
Fleeting water
As it passed by Donaldjohanson at 30,000 mph, Lucy recorded the signatures of iron-rich clay minerals on the surface. These clays must have formed in the distant past with the help of liquid water. However, the exposure must have been brief, Lucy scientists concluded, because iron in clays tends to be replaced with other elements, such as magnesium, as water lingers.
Indeed, scientists saw magnesium-rich clays at Bennu and Ryugu, which suggested prolonged water exposure, perhaps lasting millions of years, when they were still part of larger asteroids.
This difference in water exposure history, and other characteristics, may mean that the parent bodies of these asteroids formed at different times or in different regions of the solar system before relocating to the main belt.
Compare, contrast
Donaldjohanson is thought to be made from rocky remnants of a larger, carbon- and water-rich asteroid that collided with another object in the main asteroid belt. Bennu and Ryugu are thought to have formed in the same way and in the same region.
But Donaldjohanson is different. At 155 million years old, it is much younger than Bennu and Ryugu, which formed 1 to 2 billion years ago. Donaldjohanson also has remained in the asteroid belt since birth, while its wandering cousins migrated into orbits around the Sun that bring them close to Earth’s orbit about once a year (which made them perfect close targets for sample return missions).
During its April 20, 2025, encounter with the main-belt asteroid Donaldjohanson, NASA’s Lucy spacecraft discovered evidence for iron-rich clays on the surface using its infrared spectrometer. These clays, which are similar to those found in carbon-rich meteorites such as QUE 97990, indicate that water was briefly present in the asteroid during the distant past.

“It’s helpful for scientists to compare Donaldjohanson with asteroids like Bennu and Ryugu, which are seemingly similar asteroids, because every subtle difference is another clue to our origin story,” said Simone Marchi, Lucy deputy principal investigator and lead author of the study at the Boulder, Colorado, office of the Southwest Research Institute.
“Once we start learning more about the Trojans, a completely different population of space rocks with very different histories, our understanding of solar system formation is destined to be challenged,” said Marchi.
Named after a fossilized skeleton of a human ancestor discovered in Ethiopia in 1974, NASA’s Lucy will be the first mission to explore Jupiter’s Trojan asteroids, a population of well-preserved space rocks that formed early in our solar system’s history and could help scientists understand how the planets formed and moved around before settling in their current configuration.
Lucy’s principal investigator is based out of the Boulder, Colorado, branch of Southwest Research Institute, headquartered in San Antonio. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space in Littleton, Colorado, built the spacecraft. Lucy is the 13th mission in NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Discovery Program for the agency’s Science Mission Directorate in Washington.

Zooming through the main asteroid belt toward one of the Jupiter Trojan asteroid groups, the Lucy spacecraft collected the first close-up images and other data at Donaldjohanson on April 20, 2025, as it passed 650 miles away from the asteroid. The data revealed that, instead of spinning simply around one axis like most other asteroids and planets, Donaldjohanson has a more complicated two-axis rotation. Scientists also saw Donaldjohanson’s peanut shape and the craters and ridges on its surface.
Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history. Formed as fragments coalesced after a violent collision 155 million years ago, the asteroid was transformed by the small but inexorable force of the Sun’s radiation, all while retaining signs of the brief presence of liquid water in its distant past.

The L’LORRI (Lucy Long Range Reconnaissance Imager) instrument, the spacecraft’s high-resolution black-and-white imager, collected these images over two hours as the spacecraft rapidly closed in on the asteroid from an initial separation of more than 58,000 miles (93,000 km), until the spacecraft passed a mere 650 miles (1000 km) from the 5-mile- (8 km-) wide asteroid.

Lucy’s encounter with the asteroid was planned as a dress rehearsal for the spacecraft and mission team before its primary asteroid encounters, which begin with Lucy’s flyby of the Trojan asteroid Eurybates on Aug. 12, 2027. The instruments performed as expected, and, as a bonus, scientists got a rare opportunity to study a previously unexplored asteroid up close and to compare it to two asteroids with similar compositions but different histories: Bennu, the target of NASA’s OSIRIS-REx sample-return mission, and Ryugu, the site of JAXA’s (Japan Aerospace Exploration Agency) Hayabusa2 sample-return mission.
With Earth-based telescopes, observers saw fluctuations in the light Donaldjohanson reflects, regular patterns of peaks and valleys, typical of an elongated object rotating once every 10.5 Earth days. But Lucy’s data revealed another pattern: Donaldjohanson appears to be rotating like a wobbly top. Paper authors reported that the asteroid rotates end-over-end once every 10.5 Earth days, and wobbles back and forth around its long axis once every 26.5 days.
The asteroid Donaldjohanson is shown slowly rotating in a tumbling, non-principal axis motion, with its angular momentum vector and rotation axes indicated. The surface is colored by gravity slope, which measures the angle between the local surface and the direction of gravity. Higher values (warmer colors) indicate steeper terrain relative to the local gravitational pull. Regions with limited stereo image coverage have been masked out where the shape model is less well constrained.

Peanut shape
While the Earth-based observations hinted at Donaldjohanson’s elongated shape, the Lucy flyby revealed a “bilobate” structure: two lobes connected by a neck, like a peanut. These lobes are likely two fragments from an asteroid collision that gently came together afterward by their mutual gravity.
Donaldjohanson likely rotated at least 10 times faster when it formed, having slowed to its current rate in the last 20 to 60 million years, the team estimates. As it slowed, the balance between the centrifugal force pushing things apart and gravity pulling things together changed and loose rocky material slid down slopes creating the worn-down appearance of many craters, as the flyby images showed.
The paper’s authors say that the asteroid’s slowing rotation is likely caused by a subtle consequence of solar heating known as the YORP effect. Each part of the asteroid’s Sun-warmed surface radiates heat away as infrared light, and that radiation imparts a tiny recoil force to the surface. Because the asteroid’s shape isn’t symmetric, this results in a net torque, or twist, that can change the asteroid’s rotation. Thus, YORP can slow asteroid spins down or speed them up, as in the case of Bennu (once every four hours) and Ryugu (once about every seven hours), which both likely used to rotate much slower than they do today.
Fleeting water
As it passed by Donaldjohanson at 30,000 mph, Lucy recorded the signatures of iron-rich clay minerals on the surface. These clays must have formed in the distant past with the help of liquid water. However, the exposure must have been brief, Lucy scientists concluded, because iron in clays tends to be replaced with other elements, such as magnesium, as water lingers.
Indeed, scientists saw magnesium-rich clays at Bennu and Ryugu, which suggested prolonged water exposure, perhaps lasting millions of years, when they were still part of larger asteroids.
This difference in water exposure history, and other characteristics, may mean that the parent bodies of these asteroids formed at different times or in different regions of the solar system before relocating to the main belt.
Compare, contrast
Donaldjohanson is thought to be made from rocky remnants of a larger, carbon- and water-rich asteroid that collided with another object in the main asteroid belt. Bennu and Ryugu are thought to have formed in the same way and in the same region.
But Donaldjohanson is different. At 155 million years old, it is much younger than Bennu and Ryugu, which formed 1 to 2 billion years ago. Donaldjohanson also has remained in the asteroid belt since birth, while its wandering cousins migrated into orbits around the Sun that bring them close to Earth’s orbit about once a year (which made them perfect close targets for sample return missions).
During its April 20, 2025, encounter with the main-belt asteroid Donaldjohanson, NASA’s Lucy spacecraft discovered evidence for iron-rich clays on the surface using its infrared spectrometer. These clays, which are similar to those found in carbon-rich meteorites such as QUE 97990, indicate that water was briefly present in the asteroid during the distant past.

“It’s helpful for scientists to compare Donaldjohanson with asteroids like Bennu and Ryugu, which are seemingly similar asteroids, because every subtle difference is another clue to our origin story,” said Simone Marchi, Lucy deputy principal investigator and lead author of the study at the Boulder, Colorado, office of the Southwest Research Institute.
“Once we start learning more about the Trojans, a completely different population of space rocks with very different histories, our understanding of solar system formation is destined to be challenged,” said Marchi.
