Like a game of cosmic bumper cars, scientists think the early days of our solar system were a time of violent turmoil, with planetesimals, asteroids, and comets smashing together and pelting the Earth, Moon, and the other inner planets with debris. Now, in a historical milestone, NASA’s Hubble Space Telescope has directly imaged similar catastrophic collisions in a nearby planetary system around another star, Fomalhaut.
“This is certainly the first time I’ve ever seen a point of light appear out of nowhere in an exoplanetary system,” said principal investigator Paul Kalas of the University of California, Berkeley. “It’s absent in all of our previous Hubble images, which means that we just witnessed a violent collision between two massive objects and a huge debris cloud unlike anything in our own solar system today. Amazing!”
Just 25 light-years from Earth, Fomalhaut is one of the brightest stars in the night sky. Located in the constellation Piscis Austrinus, also known as the Southern Fish, it is more massive and brighter than the Sun and is encircled by several belts of dusty debris.
This composite Hubble Space Telescope image shows the debris ring and dust clouds cs1 and cs2 around the star Fomalhaut. Fomalhaut itself is masked out to allow the fainter features to be seen. Its location is marked by the white star.Image: NASA, ESA, Paul Kalas (UC Berkeley); Image Processing: Joseph DePasquale (STScI)In 2008, scientists used Hubble to discover a candidate planet around Fomalhaut, making it the first stellar system with a possible planet found using visible light. That object, called Fomalhaut b, now appears to be a dust cloud masquerading as a planet—the result of colliding planetesimals. While searching for Fomalhaut b in recent Hubble observations, scientists were surprised to find a second point of light at a similar location around the star. They call this object “circumstellar source 2” or “cs2” while the first object is now known as “cs1.”
Tackling Mysteries of Colliding PlanetesimalsWhy astronomers are seeing both of these debris clouds so physically close to each other is a mystery. If the collisions between asteroids and planetesimals were random, cs1 and cs2 should appear by chance at unrelated locations. Yet, they are positioned intriguingly near each other along the inner portion of Fomalhaut’s outer debris disk.
Another mystery is why scientists have witnessed these two events within such a short timeframe. “Previous theory suggested that there should be one collision every 100,000 years, or longer. Here, in 20 years, we’ve seen two,” explained Kalas. “If you had a movie of the last 3,000 years, and it was sped up so that every year was a fraction of a second, imagine how many flashes you’d see over that time. Fomalhaut’s planetary system would be sparkling with these collisions.”
Collisions are fundamental to the evolution of planetary systems, but they are rare and difficult to study.
This artist’s concept shows the sequence of events leading up to the creation of dust cloud cs2 around the star Fomalhaut. In Panel 1, the star Fomalhaut appears in the top left corner. Two white dots, located in the bottom right corner, represent the two massive objects in orbit around Fomalhaut. In Panel 2, the objects approach each other. Panel 3 shows the violent collision of these two objects. In Panel 4, the resulting dust cloud cs2 becomes visible and starlight pushes the dust grains away from the star.Artwork: NASA, ESA, STScI, Ralf Crawford (STScI)“The exciting aspect of this observation is that it allows researchers to estimate both the size of the colliding bodies and how many of them there are in the disk, information which is almost impossible to get by any other means,” said co-author Mark Wyatt at the University of Cambridge in England. “Our estimates put the planetesimals that were destroyed to create cs1 and cs2 at just 37 miles or 60 kilometers across, and we infer that there are 300 million such objects orbiting in the Fomalhaut system.”
“The system is a natural laboratory to probe how planetesimals behave when undergoing collisions, which in turn tells us about what they are made of and how they formed,” explained Wyatt.
Cautionary TaleThe transient nature of Fomalhaut cs1 and cs2 poses challenges for future space missions aiming to directly image exoplanets. Such telescopes may mistake dust clouds like cs1 and cs2 for actual planets.
“Fomalhaut cs2 looks exactly like an extrasolar planet reflecting starlight,” said Kalas. “What we learned from studying cs1 is that a large dust cloud can masquerade as a planet for many years. This is a cautionary note for future missions that aim to detect extrasolar planets in reflected light.”
Looking to FutureKalas and his team have been granted Hubble time to monitor cs2 over the next three years. They want to see how it evolves—does it fade, or does it get brighter? Being closer to the dust belt than cs1, the expanding cs2 cloud is more likely to start encountering other material in the belt. This could lead to a sudden avalanche of more dust in the system, which could cause the whole surrounding area to get brighter.
Credit: NASA’s Goddard Space Flight Center; Lead Producer: Paul Morris“We will be tracing cs2 for any changes in its shape, brightness, and orbit over time,” said Kalas, “It’s possible that cs2 will start becoming more oval or cometary in shape as the dust grains are pushed outward by the pressure of starlight.”
The team also will use the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope to observe cs2. Webb’s NIRCam has the ability to provide color information that can reveal the size of the cloud’s dust grains and their composition. It can even determine if the cloud contains water ice.
Hubble and Webb are the only observatories capable of this kind of imaging. While Hubble primarily sees in visible wavelengths, Webb could view cs2 in the infrared. These different, complementary wavelengths are needed to provide a broad multi-spectral investigation and a more complete picture of the mysterious Fomalhaut system and its rapid evolution.
This research appears in the December 18 issue of Science.

NASA, Boeing Test How to Improve Performance of Longer, Narrower Aircraft Wings
5 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) The Integrated Adaptive Wing Technology Maturation wind-tunnel model installed in the Transonic Dynamics Tunnel at NASA Langley Research Center in Hampton, Virginia.NASA / Mark KnoppThe airliner you board in the future could look a lot different from today’s, with longer, thinner wings that provide a smoother ride while saving fuel.
Those wings would be a revolutionary design for commercial aircraft, but like any breakthrough technology, they come with their own development challenges – which experts from NASA and Boeing are now working to solve.
When creating lift, longer, thinner wings can reduce drag, making them efficient. However, they can become very flexible in flight.
Through their Integrated Adaptive Wing Technology Maturation collaboration, NASA and Boeing recently completed wind tunnel tests of a “higher aspect ratio wing model” looking for ways to get the efficiency gains without the potential issues these kinds of wings can experience.
“When you have a very flexible wing, you’re getting into greater motions,” said Jennifer Pinkerton, a NASA aerospace engineer at NASA Langley Research Center in Hampton, Virginia. “Things like gust loads and maneuver loads can cause even more of an excitation than with a smaller aspect ratio wing. Higher aspect ratio wings also tend to be more fuel efficient, so we’re trying to take advantage of that while simultaneously controlling the aeroelastic response.”
Take a minute to watch this video about the testing NASA and Boeing are doing on longer, narrower aircraft wings.
Without the right engineering, long, thin wings could potentially bend or experience a condition known as wing flutter, causing aircraft to vibrate and shake in gusting winds.
“Flutter is a very violent interaction,” Pinkerton said. “When the flow over a wing interacts with the aircraft structure and the natural frequencies of the wing are excited, wing oscillations are amplified and can grow exponentially, leading to potentially catastrophic failure. Part of the testing we do is to characterize aeroelastic instabilities like flutter for aircraft concepts so that in actual flight, those instabilities can be safely avoided.”
To help demonstrate and understand this, researchers from NASA and Boeing sought to soften the impacts of wind gusts on the aircraft, lessen the wing loads from aircraft turns and movements, and suppress wing flutter.
Reducing or controlling those factors can have a significant impact on an aircraft’s performance, fuel efficiency, and passenger comfort.
Testing for this in a controlled environment is impossible with a full-sized commercial airliner, as no wind tunnel could accommodate one.
However, NASA Langley’s Transonic Dynamics Tunnel, which has been contributing to the design of U.S. commercial transports, military aircraft, launch vehicles, and spacecraft for over 60 years, features a test section 16 feet high by 16 feet wide, big enough for large-scale models.
To shrink a full-size plane down to scale, NASA and Boeing worked with NextGen Aeronautics, which designed and fabricated a complex model resembling an aircraft divided down the middle, with one 13-foot wing.
Mounted to the wall of the wind tunnel, the model was outfitted with 10 control surfaces – moveable panels – along the wing’s rear edge. Researchers adjusted those control surfaces to control airflow and reduce the forces that were causing the wing to vibrate.
Instruments and sensors mounted inside the model measured the forces acting on the model, as well as the vehicle’s responses.
Another view of the Integrated Adaptive Wing Technology Maturation wind-tunnel model installed in the Transonic Dynamics Tunnel at NASA Langley Research Center in Hampton, Virginia.NASA / Mark KnoppThe model wing represented a leap in sophistication from a smaller one developed during a previous NASA-Boeing collaboration called the Subsonic Ultra Green Aircraft Research (SUGAR).
“The SUGAR model had two active control surfaces,” said Patrick S. Heaney, principal investigator at NASA for the Integrated Adaptive Wing Technology Maturation collaboration. “And now on this particular model we have ten. We’re increasing the complexity as well as expanding what our control objectives are.”
A first set of tests, conducted in 2024, gave experts baseline readings that they compared to NASA computational simulations, allowing them to refine their models. A second set of tests in 2025 used the additional control surfaces in new configurations.
The most visible benefits of these new capabilities appeared during testing to alleviate the forces from gusting winds, when researchers saw the wing’s shaking greatly reduced.
With testing completed, NASA and Boeing experts are analyzing data and preparing to share their results with the aviation community. Airlines and original equipment manufacturers can learn and benefit from the lessons learned, deciding which to apply to the next generation of aircraft.
“Initial data analyses have shown that controllers developed by NASA and Boeing and used during the test demonstrated large performance improvements,” Heaney said. “We’re excited to continue analyzing the data and sharing results in the months to come.”
NASA’s Advanced Air Transport Technology project works to advance aircraft design and technology under the agency’s Advanced Air Vehicles program, which studies, evaluates, and develops technologies and capabilities for new aircraft systems. The project and program fall within NASA’s Aeronautics Research Mission Directorate.

It transitions between observations of colors emitted by hot hydrogen gas (blue) and cosmic dust (red), and those primarily emitted by stars.Credit: NASA/JPL-Caltech
Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. While not visible to the human eye, these 102 infrared wavelengths of light are prevalent in the cosmos, and observing the entire sky this way enables scientists to answer big questions, including how a dramatic event that occurred in the first billionth of a trillionth of a trillionth of a second after the big bang influenced the 3D distribution of hundreds of millions of galaxies in our universe. In addition, scientists will use the data to study how galaxies have changed over the universe’s nearly 14 billion-year history and learn about the distribution of key ingredients for life in our own galaxy.
“It’s incredible how much information SPHEREx has collected in just six months — information that will be especially valuable when used alongside our other missions’ data to better understand our universe,” said Shawn Domagal-Goldman, director of the Astrophysics Division at NASA Headquarters in Washington. “We essentially have 102 new maps of the entire sky, each one in a different wavelength and containing unique information about the objects it sees. I think every astronomer is going to find something of value here, as NASA’s missions enable the world to answer fundamental questions about how the universe got its start, and how it changed to eventually create a home for us in it.”
Circling Earth about 14½ times a day, SPHEREx (which stands for Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) travels from north to south, passing over the poles. Each day it takes about 3,600 images along one circular strip of the sky, and as the days pass and the planet moves around the Sun, SPHEREx’s field of view shifts as well. After six months, the observatory has looked out into space in every direction, capturing the entire sky in 360 degrees.
Managed by NASA’s Jet Propulsion Laboratory in Southern California, the mission began mapping the sky in May and completed its first all-sky mosaic in December. It will complete three additional all-sky scans during its two-year primary mission, and merging those maps together will increase the sensitivity of the measurements. The entire dataset is freely available to scientists and the public.
“SPHEREx is a mid-sized astrophysics mission delivering big science,” said JPL Director Dave Gallagher. “It’s a phenomenal example of how we turn bold ideas into reality, and in doing so, unlock enormous potential for discovery.”
NASA’s SPHEREx has mapped the entire sky in 102 infrared colors, which are invisible to the human eye but can be used to reveal different features of the cosmos. This image features a selection of colors emitted primarily by stars (blue, green, and white), hot hydrogen gas (blue), and cosmic dust (red). NASA/JPL-Caltech This SPHEREx image shows a selection of the infrared colors primarily emitted by stars and galaxies. The space telescope is observing hundreds of millions of distant galaxies across the sky. Its multiwavelength view will help astronomers measure the distance to those galaxies. NASA/JPL-Caltech The infrared colors emitted primarily by dust (red) and hot gas (blue), key ingredients for forming new stars and planets, are seen in this SPHEREx image. Though these clouds of material cover a massive portion of the sky, they are invisible in most wavelengths of light, including those the human eye can detect. NASA/JPL-Caltech Superpowered telescopeEach of the 102 colors detected by SPHEREx represents a wavelength of infrared light, and each wavelength provides unique information about the galaxies, stars, planet-forming regions, and other cosmic features therein. For example, dense clouds of dust in our galaxy where stars and planets form radiate brightly in certain wavelengths but emit no light (and are therefore totally invisible) in others. The process of separating the light from a source into its component wavelengths is called spectroscopy.
And while a handful of previous missions has also mapped the entire sky, such as NASA’s Wide-field Infrared Survey Explorer, none have done so in nearly as many colors as SPHEREx. By contrast, NASA’s James Webb Space Telescope can do spectroscopy with significantly more wavelengths of light than SPHEREx, but with a field of view thousands of times smaller. The combination of colors and such a wide field of view is why SPHEREx is so powerful.
“The superpower of SPHEREx is that it captures the whole sky in 102 colors about every six months. That’s an amazing amount of information to gather in a short amount of time,” said Beth Fabinsky, the SPHEREx project manager at JPL. “I think this makes us the mantis shrimp of telescopes, because we have an amazing multicolor visual detection system and we can also see a very wide swath of our surroundings.”
To accomplish this feat, SPHEREx uses six detectors, each paired with a specially designed filter that contains a gradient of 17 colors. That means every image taken with those six detectors contains 102 colors (six times 17). It also means that every all-sky map that SPHEREx produces is really 102 maps, each in a different color.
The observatory will use those colors to measure the distance to hundreds of millions of galaxies. Though the positions of most of those galaxies have already been mapped in two dimensions by other observatories, SPHEREx’s map will be in 3D, enabling scientists to measure subtle variations in the way galaxies are clustered and distributed across the universe.
Each frame of this movie shows the entire sky in a different infrared wavelength, indicated by the color bar in the top right corner. Taken by NASA’s SPHEREx observatory, the maps illustrate how viewing the universe in different wavelengths of light can reveal unique cosmic features.Credit: NASA/JPL-Caltech
Those measurements will offer insights into an event that took place in the first billionth of a trillionth of a trillionth of a second after the big bang. In this moment, called inflation, the universe expanded by a trillion-trillionfold. Nothing like it has occurred in the universe since, and scientists want to understand it better. The SPHEREx mission’s approach is one way to help in that effort.
More about SPHERExThe SPHEREx mission is managed by JPL for NASA’s Astrophysics Division within the Science Mission Directorate in Washington. The telescope and the spacecraft bus were built by BAE Systems. The science analysis of the SPHEREx data is being conducted by a team of scientists at 10 institutions across the U.S., and in South Korea and Taiwan. Data is processed and archived at IPAC at Caltech in Pasadena, which manages JPL for NASA. The mission’s principal investigator is based at Caltech with a joint JPL appointment. The SPHEREx dataset is publicly available.

A Look Back at NASA Stennis in 2025
5 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater)In 2025, NASA’s Stennis Space Center near Bay St. Louis, Mississippi, marked a year of progress by supporting NASA’s Artemis campaign, celebrating historic milestones, and continuing its role as a trusted propulsion test partner at America’s largest rocket propulsion test site.
“For more than six decades, NASA Stennis has proudly represented the Gulf Coast region and America in advancing our nation’s space exploration goals,” said NASA Stennis Director John Bailey. “This year, we continued our progress forward as we near the launch of Artemis II, while honoring milestones that have brought our center to this point.”
Supporting ArtemisAs NASA prepares for the launch of Artemis II in early 2026, with the first crewed mission to the Moon in over 50 years, NASA Stennis continues its frontline work.
Every RS-25 engine used to help launch NASA’s SLS (Space Launch System) rocket to the Moon is tested in south Mississippi.
NASA Stennis teams provided data to lead engines contractor L3Harris Technologies by successfully testing two new production RS-25 flight engines.
NASA tested RS-25 engine No. 20001 at the Fred Haise Test Stand in June, and RS-25 engine No. 20002 in November. Each engine fired for 500 seconds, reaching 111% of its rated power, while simulating launch conditions.

Companies that have conducted work at NASA Stennis include Blue Origin, Boeing, Evolution Space; Launcher, a Vast company; Relativity Space and Rolls-Royce.
Three companies – Relativity Space, Rocket Lab, and Evolution Space – have established, or continue progress to establish, production and/or test operations at NASA Stennis.
Infrastructure upgrades and planning efforts across the test complex are laying the foundation for future propulsion test projects as well.
“As the commercial space industry continues to accelerate their development, NASA Stennis is adapting to meet their propulsion testing needs,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate. “We are proud that our proven experience makes us a trusted partner.”
Honoring the Past In 2025, NASA Stennis honored a defining era of space shuttle main engine testing. An image shows the first space shuttle main engine installed on May 8, 1975, at the Fred Haise Test Stand (formerly A-1).NASAWhile NASA Stennis operates as the nation’s largest rocket propulsion test site, the NASA Stennis Federal City also is home to more than 50 federal, state, academic, and commercial tenants.
This year marked the birth of the federal city concept 55 years ago. The unique operating approach serves as a model of government efficiency and a powerful economic engine for the Gulf Coast region.
Meanwhile, the 50th anniversary of space shuttle main engine testing honored a defining era for NASA Stennis.
From May 1975 to July 2009, NASA Stennis tested space shuttle main engines that enabled 135 shuttle missions and notable space milestones, like deployment of the Hubble Space Telescope and construction of the International Space Station.
Both the federal city model and the decades of propulsion excellence continue to inform work at NASA Stennis.
Engineering the FutureInnovation extended beyond the test stands. The versatile testing environment at NASA Stennis is uniquely positioned to support unmanned systems testing across air, land, and water. With restricted airspace, a closed canal system, and vast protected terrain, the site offers a safe, flexible environment for range operations.
In addition to physical infrastructure, NASA Stennis progressed in digital innovation with the release of its first open-source software tool to streamline propulsion test data collection and collaboration across NASA and industry. The peer review tool is designed to facilitate more efficient and collaborative creation of systems applications, such as those used in frontline government and propulsion test work.

Written by Margaret Deahn, Ph.D. student at Purdue University
NASA’s Mars 2020 rover is currently trekking towards exciting new terrain. After roughly four months of climbing up and over the rim of Jezero crater, the rover is taking a charming tour of the plains just beyond the western crater rim, fittingly named “Lac de Charmes.” This area just beyond Jezero’s rim will be the prime place to search for pre-Jezero ancient bedrock and Jezero impactites — rocks produced or affected by the impact event that created Jezero crater.
The formation of a complex crater like Jezero is, well… complex. Scientists who study impact craters like to split the formation process into three stages: contact & compression (when the impactor hits), excavation (when materials are thrown out of the crater), and modification (when gravity causes everything to collapse). This process happens incredibly fast, fracturing the impacted rock and even melting some of the target material. Sometimes on Earth, the classic “bowl” shaped crater has been completely weathered and unrecognizable, so geologists are able to identify craters by the remnants of their impactites. Just when you thought it couldn’t get any more complicated — Jezero crater’s rim is located on the rim of another, even bigger basin called Isidis. That means there is an opportunity to have impactites from both cratering events exposed in and just around the rim — some of which could be several billions of years old! We may have already encountered one of these blocks on our trek towards Lac de Charmes. In the foreground of this image taken by the Mastcam-Z instrument on the rover, there is a potential impactite called a “megablock” that the team has named “Hyha.” We can actually see this block from orbit, it is that large! The team is excited to continue exploring these ancient rocks as we take our next steps off Jezero’s rim.

NASA’s Perseverance Mars Rover Ready to Roll for Miles in Years Ahead
After nearly five years on Mars, NASA’s Perseverance rover has traveled almost 25 miles (40 kilometers), and the mission team has been busy testing the rover’s durability and gathering new science findings on the way to a new region nicknamed “Lac de Charmes,” where it will be searching for rocks to sample in the coming year.
Like its predecessor Curiosity, which has been exploring a different region of Mars since 2012, Perseverance was made for the long haul. NASA’s Jet Propulsion Laboratory in Southern California, which built Perseverance and leads the mission, has continued testing the rover’s parts here on Earth to make sure the six-wheeled scientist will be strong for years to come. This past summer, JPL certified that the rotary actuators that turn the rover’s wheels can perform optimally for at least another 37 miles (60 kilometers); comparable brake testing is underway as well.
Over the past two years, engineers have extensively evaluated nearly all the vehicle’s subsystems in this way, concluding that they can operate until at least 2031.
NASA’s Perseverance used its navigation cameras to capture its record-breaking drive of 1,350.7 feet (411.7 meters) on June 19, 2025. The navcam images were combined with rover data and placed into a 3D virtual environment, resulting in this reconstruction with virtual frames inserted about every 4 inches (0.1 meters) of drive progress. Credit: NASA/JPL-Caltech“These tests show the rover is in excellent shape,” said Perseverance’s deputy project manager, Steve Lee of JPL, who presented the results on Wednesday at the American Geophysical Union’s annual meeting, the largest gathering of planetary scientists in the United States. “All the systems are fully capable of supporting a very long-term mission to extensively explore this fascinating region of Mars.”
Perseverance has been driving through Mars’ Jezero Crater, the site of an ancient lake and river system, where it has been collecting scientifically compelling rock core samples. In fact, in September, the team announced that a sample from a rock nicknamed “Cheyava Falls” contains a potential fingerprint of past microbial life.
More efficient rovingIn addition to a hefty suite of six science instruments, Perseverance packs more autonomous capabilities than past rovers. A paper published recently in IEEE Transactions on Field Robotics highlights an autonomous planning tool called Enhanced Autonomous Navigation, or ENav. The software looks up to 50 feet (15 meters) ahead for potential hazards, then chooses a path without obstacles and tells Perseverance’s wheels how to steer there.
Engineers at JPL meticulously plan each day of the rover’s activities on Mars. But once the rover starts driving, it’s on its own and sometimes has to react to unexpected obstacles in the terrain. Past rovers could do this to some degree, but not if these obstacles were clustered near each other. They also couldn’t react as far in advance, resulting in the vehicles driving slower while approaching sand pits, rocks, and ledges. In contrast, ENav’s algorithm evaluates each rover wheel independently against the elevation of terrain, trade-offs between different routes, and “keep-in” or “keep-out” areas marked by human operators for the path ahead.
“More than 90% of Perseverance’s journey has relied on autonomous driving, making it possible to quickly collect a diverse range of samples,” said JPL autonomy researcher Hiro Ono, a paper lead author. “As humans go to the Moon and even Mars in the future, long-range autonomous driving will become more critical to exploring these worlds.”
New scienceA paper published Wednesday in Science details what Perseverance discovered in the “Margin Unit,” a geologic area at the margin, or inner edge, of Jezero Crater. The rover collected three samples from that region. Scientists think these samples may be particularly useful for showing how ancient rocks from Mars’ deep interior interacted with water and the atmosphere, helping create conditions supportive for life.
From September 2023 to November 2024, Perseverance ascended 1,312 feet (400 meters) of the Margin Unit, studying rocks along the way — especially those containing the mineral olivine. Scientists use minerals as timekeepers because crystals within them can record details about the precise moment and conditions in which they formed.
Jezero Crater and the surrounding area holds large reserves of olivine, which forms at high temperatures, typically deep within a planet, and offers a snapshot of what was going on in the planet’s interior. Scientists think the Margin Unit’s olivine was made in an intrusion, a process where magma pushes into underground layers and cools into igneous rock. In this case, erosion later exposed that rock to the surface, where it could interact with water from the crater’s ancient lake and carbon dioxide, which was abundant in the planet’s early atmosphere.
Those interactions form new minerals called carbonates, which can preserve signs of past life, along with clues as to how Mars’ atmosphere changed over time.
“This combination of olivine and carbonate was a major factor in the choice to land at Jezero Crater,” said the new paper’s lead author, Perseverance science team member Ken Williford of Blue Marble Space Institute of Science in Seattle. “These minerals are powerful recorders of planetary evolution and the potential for life.”
Together, the olivine and carbonates record the interplay between rock, water, and atmosphere inside the crater, including how each changed over time. The Margin Unit’s olivine appeared to have been altered by water at the base of the unit, where it would have been submerged. But the higher Perseverance went, the more the olivine bore textures associated with magma chambers, like crystallization, and fewer signs of water alteration.
As Perseverance leaves the Margin Unit behind for Lac de Charmes, the team will have the chance to collect new olivine-rich samples and compare the differences between the two areas.

Massive Stars Make Their Mark in Hubble Image
This NASA/ESA Hubble Space Telescope image features a glittering blue dwarf galaxy called Markarian 178 (Mrk 178). The galaxy, which is substantially smaller than our own Milky Way, lies 13 million light-years away in the constellation Ursa Major (the Great Bear).
Mrk 178 is one of more than 1,500 Markarian galaxies. These galaxies get their name from the Armenian astrophysicist Benjamin Markarian, who compiled a list of galaxies that were surprisingly bright in ultraviolet light.
While the bulk of the galaxy is blue due to an abundance of young, hot stars with little dust shrouding them, Mrk 178 gets a red hue from a collection of rare massive Wolf–Rayet stars. These stars are concentrated in the brightest, reddish region near the galaxy’s edge. Wolf–Rayet stars cast off their atmospheres through powerful winds, and the bright emission lines from their hot stellar winds are etched upon the galaxy’s spectrum. Both ionized hydrogen and oxygen lines are particularly strong and appear as a red color in this photo.
Massive stars enter the Wolf–Rayet phase of their evolution just before they collapse into black holes or neutron stars. Because Wolf–Rayet stars last for only a few million years, researchers know that something must have triggered a recent burst of star formation in Mrk 178. At first glance, it’s not clear what could be the cause — Mrk 178 doesn’t seem to have any close galactic neighbors that may have stirred up its gas to form new stars. Instead, researchers suspect that a gas cloud crashed into Mrk 178, or that the intergalactic medium disturbed its gas as the galaxy moved through space. Either disturbance could light up this tiny galaxy with a ripple of bright new stars.

Preparations for Next Moonwalk Simulations Underway (and Underwater) Dual Propulsion Experiment (DUPLEX) deploys from the International Space Station December 2, 2025.NASANASA is working with commercial partners to create high-performing, reliable propulsion systems that will help small spacecraft safely maneuver in orbit, reach intended destinations across the solar system, and accomplish mission operations.
Two new micropropulsion technologies are being tested in space onboard a CubeSat called DUPLEX (Dual Propulsion Experiment) that deployed into low Earth orbit from the International Space Station on Dec. 2. The CubeSat is fitted with two thruster systems that use spools of polymer fibers to provide performance levels of propulsion comparable to existing systems but with greater safety during assembly and more affordability.
One of the propulsion technologies is a fiber-fed pulsed plasma thruster system which employs an electric pulse to vaporize Teflon material and uses the resulting ions to deliver strong, efficient thrust while using very little fuel. The other propulsion technology is a monofilament vaporization propulsion system – inspired by 3D printers – which heats and vaporizes a common polymer material known as Delrin to create continuous thrust.
On orbit, DUPLEX will test its advanced propulsion systems by raising and lowering its orbit over two years, demonstrating the systems’ capabilities to maintain a vehicle’s orbit over time. Micropropulsion solutions enable a variety of cost-efficient capabilities necessary for operators in a bustling low Earth orbit economy, including maintaining and adjusting orbits to avoid debris or nearby spacecraft, and coordinating maneuvers between spacecraft to perform maintenance, inspections, and other critical activities. The systems tested on DUPLEX can also make spacecraft capable of lower cost extended missions in areas that are farther from Earth, such as the Moon and Mars.
Technologies like those demonstrated onboard DUPLEX open the door for U.S. industry to provide efficient, affordable spacecraft systems for various space-based applications, building a stronger orbital economy to meet the needs of NASA and the nation.
The DUPLEX spacecraft was developed by Champaign-Urbana Aerospace in Illinois. NASA’s Small Spacecraft and Distributed Systems program at the agency’s Ames Research Center in California’s Silicon Valley supported the development, with funding from the Small Business Innovation Research program and a 2019 Tipping Point industry partnership award through the agency’s Space Technology Mission Directorate.

NASA’s Push Toward Commercial Space Communications Gains Momentum
NASA’s commercial partners are actively demonstrating next-generation satellite relay capabilities for spaceflight missions, marking a significant step toward retiring the agency’s Tracking and Data Relay Satellite (TDRS) system and adopting commercial services. The demonstrations – ranging from real-time spacecraft tracking during launch to transmitting mission commands and scientific data – are part of NASA’s Communications Services Project, which is modernizing how the agency communicates with its science missions in near-Earth orbit.
Managed by the agency’s SCaN (Space Communications and Navigation) Program, the project awarded funded Space Act Agreements in 2022 to six U.S. companies that are developing and testing commercial satellite communications services. The initiative supports NASA’s broader strategy to retire the TDRS constellation and adopt a commercial-first model for near-Earth communications.
“In collaboration with our commercial partners, SCaN is ushering in a new era of space exploration that will deliver powerful, forward-thinking solutions that reduce cost, increase adaptability, and increase mission success,” said Kevin Coggins, deputy associate administrator for SCaN at NASA Headquarters in Washington. “This work advances our commitment to expanding the low Earth orbit economy, and our commercial space partners are leading the charge through these groundbreaking demonstrations, proving for the first time that commercial satellite relay services can work for NASA missions.”

Telesat U.S. Services LLC, doing business as Telesat Government Solutions, is demonstrating high-rate data exchanges over optical links using its anticipated Telesat Lightspeed network in low Earth orbit.
Development of the Telesat Lightspeed satellite network is currently underway, with satellite launches planned for late 2026. These satellites will use innovative technologies, like optical inter-satellite links and advanced onboard processing, to establish a global, mesh network in space. Software-defined networks aim to enable robust and reliable routing of traffic from a space-based or terrestrial terminal to its final destination autonomously. In 2027, Telesat plans to complete multiple demonstrations of space-to-space connectivity, including an optical data exchange from a Planet Labs spacecraft in low Earth orbit to the Telesat Lightspeed constellation. The data will then be routed over optical links before getting downlinked to a Telesat landing station on Earth, representing a full end-to-end capability.

In May 2023, Viasat completed the acquisition of Inmarsat, the sixth satellite communications company to win a contract award from NASA, combining the resources of both companies to form a unified global communications provider.
Viasat’s space demonstrations will use its established satellite networks in geostationary orbit to validate three primary capabilities: launch telemetry over the L-band radio frequency to track and monitor spacecraft during ascent; command and control over L-band to maintain continuous spacecraft custody and enable real-time operations; and high-speed Ka-band data relay to transfer large volumes of mission data through next-generation spacecraft terminals. Flights test began in November, when Viasat used its satellite network to successfully track the telemetry of Blue Origin’s New Glenn rocket as it launched into low Earth orbit. Follow-on demonstrations are planned for 2026, including additional L-band launch services as well as high-capacity services over Ka-band frequencies.

NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean
6 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) This artist’s concept depicts NASA’s Cassini spacecraft performing one of its many close flybys of Titan, Saturn’s largest moon. By analyzing the Doppler shift of radio signals traveling to and from Earth, the mission precisely measured Titan’s gravity field.NASA/JPL-CaltechA key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data suggests a more complicated picture: Titan’s interior is more likely composed of ice, with layers of slush and small pockets of warm water that form near its rocky core.
Led by researchers at NASA’s Jet Propulsion Laboratory in Southern California and published in the journal Nature on Wednesday, the new study could have implications for scientists’ understanding of Titan and other icy moons throughout our solar system.
“This research underscores the power of archival planetary science data. It is important to remember that the data these amazing spacecraft collect lives on so discoveries can be made years, or even decades, later as analysis techniques get more sophisticated,” said Julie Castillo-Rogez, senior research scientist at JPL and a coauthor of the study. “It’s the gift that keeps giving.”
To remotely probe planets, moons, and asteroids, scientists study the radio frequency communications traveling back and forth between spacecraft and NASA’s Deep Space Network. It’s a multilayered process. Because a moon’s body may not have a uniform distribution of mass, its gravity field will change as a spacecraft flies through it, causing the spacecraft to speed up or slow down slightly. In turn, these variations in speed alter the frequency of the radio waves going to and from the spacecraft — an effect known as Doppler shift. Analyzing the Doppler shift can lend insight into a moon’s gravity field and its shape, which can change over time as it orbits within its parent planet’s gravitational pull.
This shape shifting is called tidal flexing. In Titan’s case, Saturn’s immense gravitational field squeezes the moon when Titan is closer to the planet during its slightly elliptical orbit, and it stretches the moon when it is farthest. Such flexing creates energy that is lost, or dissipated, in the form of internal heating.
When mission scientists analyzed radio-frequency data gathered during the now-retired Cassini mission’s 10 close approaches of Titan, they found the moon to be flexing so much that they concluded it must have a liquid interior, since a solid interior would have flexed far less. (Think of a balloon filled with water versus a billiard ball.)
New techniqueThe new research highlights another possible explanation for this malleability: an interior composed of layers featuring a mix of ice and water that allows the moon to flex. In this scenario, there would be a lag of several hours between Saturn’s tidal pull and when the moon shows signs of flexing — much slower than if the interior were fully liquid. A slushy interior would also exhibit a stronger energy dissipation signature in the moon’s gravity field than a liquid one, because these slush layers would generate friction and produce heat when the ice crystals rub against one another. But there was nothing apparent in the data to suggest this was happening.
So the study authors, led by JPL postdoctoral researcher Flavio Petricca, looked more closely at the Doppler data to see why. By applying a novel processing technique, they reduced the noise in the data. What emerged was a signature that revealed strong energy loss deep inside Titan. The researchers interpreted this signature to be coming from layers of slush, overlaid by a thick shell of solid ice.
Based on this new model of Titan’s interior, the researchers suggest that the only liquid would be in the form of pockets of meltwater. Heated by dissipating tidal energy, the water pockets slowly travel toward the frozen layers of ice at the surface. As they rise, they have the potential to create unique environments enriched by organic molecules being supplied from below and from material delivered via meteorite impacts on the surface.
“Nobody was expecting very strong energy dissipation inside Titan. But by reducing the noise in the Doppler data, we could see these smaller wiggles emerge. That was the smoking gun that indicates Titan’s interior is different from what was inferred from previous analyses,” said Petricca. “The low viscosity of the slush still allows the moon to bulge and compress in response to Saturn’s tides, and to remove the heat that would otherwise melt the ice and form an ocean.”
Potential for life“While Titan may not possess a global ocean, that doesn’t preclude its potential for harboring basic life forms, assuming life could form on Titan. In fact, I think it makes Titan more interesting,” Petricca added. “Our analysis shows there should be pockets of liquid water, possibly as warm as 20 degrees Celsius (68 degrees Fahrenheit), cycling nutrients from the moon’s rocky core through slushy layers of high-pressure ice to a solid icy shell at the surface.”
More definitive information could come from NASA’s next mission to Saturn. Launching no earlier than 2028, the agency’s Dragonfly mission to the hazy moon could provide the ground truth. The first-of-its-kind rotorcraft will explore Titan’s surface to investigate the moon’s habitability. Carrying a seismometer, the mission may provide key measurements to probe Titan’s interior, depending on what seismic events occur while it is on the surface.
More about CassiniThe Cassini-Huygens mission was a cooperative project of NASA, ESA (European Space Agency), and the Italian Space Agency. A division of Caltech in Pasadena, JPL managed the mission for NASA’s Space Mission Directorate in Washington and designed, developed, and assembled the Cassini orbiter.

NASA Langley Research Center: 2025 Year in Review
The future of flight, space exploration, and science starts at NASA’s Langley Research Center in Hampton, Virginia, where we have been advancing innovation for more than 100 years. Join us as we look back at NASA Langley’s achievements in 2025 that continued our storied legacy of pushing the boundaries of what is possible.
Langley Researchers Explore MARVL-ous Technology for Future Trips to Mars Modular Assembled Radiators for Nuclear Electric Propulsion Vehicles, or MARVL, aims to take a critical element of nuclear electric propulsion, its heat dissipation system, and divide it into smaller components that can be assembled robotically and autonomously in space. This is an artist’s rendering of what the fully assembled system might look like.NASAAs NASA returns astronauts to the Moon through the agency’s Artemis campaign in advance of human exploration of Mars, researchers at Langley are exploring technology that could significantly reduce travel time to the Red Planet. Modular Assembled Radiators for Nuclear Electric Propulsion Vehicles, or MARVL, would use robots for in-space assembly of elements needed to enable nuclear electric propulsion of future spacecraft, which could transform travel to deep space.
NASA Cameras Catch First-of-its-Kind Moon Close-upThe Moon was ready for its close-up in March, when cameras developed by a Langley team captured first-of-its-kind imagery of a lunar lander’s engine plumes interacting with the Moon’s surface during Firefly Aerospace’s Blue Ghost Mission 1. Information gathered from images like this is critical in helping NASA prepare for future crewed and uncrewed lunar landings.
Stellar Event Offers NASA Rare Look at Uranus This rendering demonstrates what is happening during a stellar occultation and illustrates an example of the light curve data graph recorded by scientists that enables them to gather atmospheric measurements, like temperature and pressure, from Uranus as the amount of starlight changes when the planet eclipses the star.NASA/Langley Research Center Advanced Concepts LaboratoryIn April, planetary scientists at Langley led an international team of astronomers during a cosmic alignment three decades in the making: a rare opportunity to study Uranus. The one-hour event gave them a glimpse into the planet’s atmosphere, information that could enable future Uranus exploration efforts.
NASA Instrument Measures Wind for Improved Weather Forecasts This visualization shows AWP 3D measurements gathered on Oct. 15, 2024, as NASA’s G-III aircraft flew along the East Coast of the U.S. and across the Great Lakes region. Laser light that returns to AWP as backscatter from aerosol particles and clouds allows for measurement of wind direction, speed, and aerosol concentration as seen in the separation of data layers. NASA Scientific Visualization StudioSevere or extreme weather can strike in a moment’s notice, and having the tools to accurately predict weather events can help save lives and property. Scientists at Langley have developed and are testing an instrument that uses laser technology to gather precise wind measurements, data that is a crucial element for accurate weather forecasting.
Langley Researchers Develop New Technique to Test Long, Flexible Booms Researchers look at a bend that occurred in the 94-foot triangular, rollable and collapsible boom during an off-axis compression test.NASA/David C. BowmanGravity can create issues when testing materials for space, but Langley researchers have found a way to successfully use gravity and height when testing long composite booms. Testing these composite booms is important because they could support space exploration in a variety of ways, including being used to build structures that could support humans living and working on the Moon.

Not only does the team support a variety of missions to advance the agency’s work, but they also collaborate with the private sector as NASA works to open space to more science, people, and opportunities.
NASA Instrument Uses Moonlight for Improved Space Measurements An artist’s rendering of NASA’s Arcstone instrument on-orbit gathering measurements of lunar reflectance.Blue Canyon TechnologiesOne of the most challenging tasks in remote sensing from space is achieving required instrument calibration on-orbit. Langley scientists are addressing the challenge head on through the Arcstone mission, an instrument that launched in June and aims to establish the Moon as a cost-efficient, high-accuracy calibration reference. Once established, the new standard can be applied to past, present, and future spaceborne sensors and satellite constellations. Arcstone uses a spectrometer, a scientific instrument that measures and analyzes light, to measure lunar spectral reflectance.
NASA Mission Continues Monitoring Air We Breathe By measuring nitrogen dioxide (NO2) and formaldehyde (HCHO), TEMPO can derive the presence of near-surface ozone. On Aug. 2, 2024 over Houston, TEMPO observed exceptionally high ozone levels in the area. On the left, NO2 builds up in the atmosphere over the city and over the Houston Ship Channel. On the right, formaldehyde levels are seen reaching a peak in the early afternoon. Formaldehyde is largely formed through the oxidation of hydrocarbons, an ingredient of ozone production, such as those that can be emitted by petrochemical facilities found in the Houston Ship Channel. NASA’s Scientific Visualization StudioThe success of NASA’s Tropospheric Emissions: Monitoring of Pollution mission, or TEMPO, earned the mission an extension, meaning the work to monitor Earth’s air quality from 22,000 miles above the ground will continue through at least September 2026. The Langley-led mission launched in 2023 and is NASA’s first to use a spectrometer, a scientific instrument that measures and analyzes light, to gather hourly air quality data continuously over North America during daytime hours. The data gathered is distributed freely to the public, giving air quality forecasters, scientists, researchers, and your next-door neighbor access to quality information about the air we breathe down to the neighborhood level.
NASA Tests New, Innovative Tech to Enable Faster Launches at Lower Costs The fully assembled and tested Athena EPIC satellite which incorporates eight HISats mounted on a mock-up of a SpaceX provided launch pedestal which will hold Athena during launch.NovaWurksNASA’s Athena Economical Payload Integration Cost mission, or Athena EPIC, launched in July with the goal to shape a future path to launch that saves taxpayers money and expedites access to space. Athena EPIC was the first NASA-led mission led to utilize HISat technology, small satellites engineered to aggregate, share resources, and conform to different sizes and shapes. Langley’s scientists designed and built the Athena sensor with spare parts from NASA’s CERES (Clouds and the Earth’s Radiant Energy System) mission to gather top of atmosphere measurements. Athena EPIC demonstrates a novel way to launch Earth-observing instruments into orbit quicker and more economically.
Drop Test at Langley Offers Research, Data for Potential Air Taxi DesignsThe future of air travel includes the safe integration of drones and air taxis into our airspace for passenger transport, cargo delivery, and public service capabilities. That is why NASA is investigating and testing potential air taxi materials and designs to help the aviation industry better understand how those materials behave under impact. Data collected from a drop test at Langley’s Landing and Impact Research Facility in June will help in the development of safety regulations for advanced air mobility aircraft, leading to safer designs.
Langley Wind Tunnel Tests Help Support Advanced Air Mobility Aircraft Development NASA researcher Norman W. Schaeffler adjusts a propellor, which is part of a 7-foot wing model that was recently tested at NASA’s Langley Research Center in Hampton, Virginia. In May and June, NASA researchers tested the wing in the 14-by-22-Foot Subsonic Wind Tunnel to collect data on critical propeller-wing interactions. The lessons learned will be shared with the public to support advanced air mobility aircraft development.NASA/Mark KnoppNASA advanced the future of air taxis and autonomous cargo drones by testing a 7-foot wing model in Langley’s 14-by-22-Foot Subsonic Wind Tunnel. This effort produced data on critical propeller-wing interactions, as well as data relevant to cruise, hover, and transition conditions for advanced air mobility aircraft. The results will help validate next-generation design tools and accelerate safe, reliable development across the advanced air mobility industry.

The lack of publicly available engineering and flight data to help address technical barriers in the design and development of new electric vertical takeoff and landing (eVTOL) aircraft is a challenge for researchers and engineers. That is why Langley researchers are using a research aircraft that provides real-world data, obtained through wind tunnel and flight tests, to help fill the information gap and check the accuracy of computer models for flight dynamics and controls. Making this data available to all is a key step in transforming the way we fly and safely integrating new aircraft into our nation’s airspace.
NASA Material Flies High for Study of Long-Term Effects of Space Robert Mosher, HIAD materials and processing lead at NASA Langley, holds up a piece of f webbing material, known as Zylon, which comprise the straps of the HIAD.NASA/Joe AtkinsonA material from NASA Langley is riding high as it orbits the Earth aboard a United States Space Force test vehicle, giving researchers a better understanding of how the material responds to long-duration exposure to the harsh vacuum of space. The strap material is a part of a Langley-developed aeroshell to protect spacecraft re-entering Earth’s atmosphere or to ensure their safe landing on other celestial bodies, such as Mars. Understanding how extended exposure to space affects the material is important as NASA prepares to send humans beyond the Moon.
NASA Flights Study Impacts of Space Weather on Travelers Frozen and rocky terrain in the Polar region observed from above Nuuk, Greenland during NASA’s SWXRAD science flights.NASA/Guillaume GronoffData gathered during a Langley-led airborne science campaign late this summer could help protect air travelers on Earth and future space travelers to the Moon, Mars, and beyond from the health risks associated with radiation exposure. NASA’s Space Weather Aviation Radiation (SWXRAD) aircraft flight campaign took place in Greenland and measured the radiation dose level to air travelers from cosmic radiation. Researchers are using the information to enhance a modeling system that offers real-time global maps of the hazardous radiation in the atmosphere and creates exposure predictions for aircraft and spacecraft.
NASA’s Dragonfly Completes Wind Tunnel Tests at Langley Set up and testing of Dragonfly model in the Transonic Dynamics TunnelNASA/David C. BowmanAs NASA returns astronauts to the Moon through the Artemis campaign in preparation for human exploration of Mars, the agency also has its sights set on Saturn, specifically Saturn’s moon Titan. NASA’s Dragonfly, a car-sized rotorcraft set to launch no earlier than 2028, will explore Titan and try to discover how life began. This fall, engineers placed a full-scale test model representing half of the Dragonfly lander in Langley’s Transonic Dynamics Tunnel to evaluate how its rotor system performed in Titan-like conditions. The data will be integral in developing the rotorcraft’s flight plans and navigation software as it investigates multiple landing sites on Titan.

NASA’s X-59 Takes FlightIn October, NASA’s Quesst mission celebrated a major milestone – the X-59 quiet supersonic one-of-a-kind research aircraft flew for the first time, a historic moment for aviation. The hard work, talent, and innovation of NASA engineers and project team members, including many based at NASA Langley, made this achievement possible. One of the notable traits of the X-59 is the eXternal Vision System (XVS) which allows the test pilots to safely maneuver the skies without a forward-facing window. This unique supersonic design feature was developed and tested at NASA Langley.
The X-59’s first flight was a major step toward quiet supersonic flight over land, which could revolutionize air travel.

Langley Inspires Through Community Engagement, Educational Opportunities NASA Langley highlights its Cirrus Design SR22 during Air Power Over Hampton Roads STEM Day. NASA/Angelique HerringLangley connected with communities across Virginia and beyond to share the center’s work and impact, and inspire the next generation of explorers, scientists, and researchers. Thousands of spectators enjoyed hands-on activities and exhibits during the Air Power over Hampton Roads air show at Joint Base Langley-Eustis in Hampton, Virginia, where NASA Langley’s aviation past, present, and future were on full display. More than 2,300 students from across the nation eagerly participated in Langley’s 2025 Student Art Contest, and shared their artistic spin on the theme, “Our Wonder Changes the World.” Langley and Embry-Riddle Aeronautical University announced an agreement in September that will leverage Langley’s aerospace expertise and Embry-Riddle’s specialized educational programs and research to drive innovation in aerospace, research, education, and technology, while simultaneously developing a highly skilled workforce for the future of space exploration and advanced air mobility.
Langley looks forward to another year of successes and advancements in 2026, as we continue to make the seemingly impossible, possible.

Icons of winter are sometimes found in unexpected places. In one striking example, a series of oval lagoons in a remote part of Siberia forms the shape of a towering snowman when viewed from above.
This image, centered on the remote village of Billings and nearby Cape Billings on Russia’s Chukchi Peninsula, was captured by the OLI (Operational Land Imager) aboard Landsat 8 on June 16, 2025. Established in the 1930s as a port and supply point for the Soviet Union, the village sits on a narrow sandspit that separates the Arctic Ocean from a series of connected coastal inshore lagoons.
The elongated, oval lagoons are frozen over and flanked by sea ice. Though June is one of the warmest months in Billings, ice cover is routine even then. Mean daily minimum temperatures are just minus 0.6 degrees Celsius (30.9 degrees Fahrenheit) in June, according to meteorological data.
Though the shape may seem engineered, it is natural and the product of geological processes common in the far north. The ground in this part of Siberia is frozen most of the year and pockmarked with spear-shaped ice wedges buried under the surface. Summer melting causes overlying soil to slump, leaving shallow depressions that fill with meltwater and form thermokarst lakes. Once created, consistency in the direction of the winds and waves likely aligned and elongated the lakes into the shapes seen in the image. The thin ridges separating the lakes may represent the edges of different ice wedges below the surface.
The first reference to humans building snowmen dates back to the Middle Ages, according to the book The History of the Snowman. While three spherical segments are the most common form, other variants dominate in certain areas. In Japan, snowmen typically have just two segments and are rarely given arms. This five-segmented snowman-shaped series of lakes spans about 22 kilometers (14 miles) from top to bottom, making it roughly 600 times longer than the actual snowwoman that held the Guinness record for being the world’s tallest snowperson in 2025.
Snowmen are not the only winter icons tied to this remote landscape. For early expeditions to the Russian Arctic, reindeer offered one of the most reliable modes of transportation. That includes expeditions by the town’s namesake, Commodore Joseph Billings, a British-born naval officer who enlisted in the Russian navy and led a surveying expedition to find a Northeast Passage between 1790 and 1794.
Although the hundred-plus members of the expedition did not reach Cape Billings, they explored much of the Chukchi Peninsula, producing some of the first accurate maps and further confirming that Asia and North America were separated by a strait. In the winter months, when their ships were beset by ice, the explorers moved to temporary camps on land and instead surveyed the region with reindeer-drawn wooden sleds, according to historical accounts. Winters, in fact, offered the best conditions for exploration because the peninsula’s many rivers and lakes turned into solid surfaces that were easy to traverse in comparison to the muddy bogs that open up in the summer.
Indigenous Chukchi people living on the peninsula at the time routinely used reindeer to haul both people and cargo. A pair of reindeer can comfortably haul hundreds of pounds for several hours a day. In addition to their impressive endurance in cold temperatures, reindeer largely feed themselves by digging through snow and grazing on lichens, something that neither sled dogs nor horses can do.
Historical documents indicate that the Billings expedition enlisted Chukchi people to manage and care for the reindeer they used, with some accounts suggesting that the explorers used dozens of reindeer at times. While reindeer were mainly used to haul sleds, Chukchi people likely rode them as well.
Non-Chukchi members of the expedition reportedly experimented with riding reindeer, though their experiments did not always go smoothly. Billings’ secretary and translator Martin Sauer reported using a saddle without stirrups or a bridle and falling “nearly 20 times” after about three hours of travel in his account of the expedition. Not only that, he added, but the saddle “at first, causes astonishing pain to the thighs.”

NASA IXPE’s Longest Observation Solves Black Hole Jets Mystery
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Two composite images show side-by-side observations of the Perseus Cluster from NASA’s IXPE (Imaging X-Ray Polarimetry Explorer) and Chandra X-ray Observatory. Scientists used data from both observatories, along with data from Nuclear Spectroscopic Telescope Array (NuSTAR), and Neil Gehrels Swift Observatory, to confirm measurements of the galaxy cluster.X-ray: (Chandra) NASA/CXC/SAO, (IXPE) NASA/MSFC; Image Processing: NASA/CXC/SAO/N. Wolk and K. ArcandWritten by Michael Allen
An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has identified the origin of X-rays in a supermassive black hole’s jet, answering a question that has been unresolved since the earliest days of X-ray astronomy. Their findings are described in a paper published in The Astrophysical Journal Letters, by the American Astronomical Society, Nov. 11.
The IXPE mission observed the Perseus Cluster, the brightest galaxy cluster observable in X-rays, for more than 600 hours over a 60-day period between January and March. Not only is this IXPE’s longest observation of a single target to date, it also marks IXPE’s first time observing a galaxy cluster.
Specifically, the team of scientists studied the polarization properties of 3C 84, the massive active galaxy located at the very center of the Perseus Cluster. This active galaxy is a well-known X-ray source and a common target for X-ray astronomers because of its proximity and brightness.
Because the Perseus Cluster is so massive, it hosts an enormous reservoir of X-ray emitting gas as hot as the core of the Sun. The use of multiple X-ray telescopes, particularly the high-resolution imaging power of NASA’s Chandra X-ray Observatory was essential to disentangle the signals in the IXPE data. Scientists combined these X-ray measurements with data from the agency’s Nuclear Spectroscopic Telescope Array (NuSTAR) mission and Neil Gehrels Swift Observatory.
Fast facts- Polarization measurements from IXPE carry information about the orientation and alignment of emitted X-ray light waves. The more X-ray waves traveling in sync, the higher the degree of polarization.
- X-rays from an active galaxy like 3C 84 are thought to originate from a process known as inverse Compton scattering, where light bounces off particles and gains energy. The polarization measurements from IXPE allow us to identify the presence of either inverse Compton scattering or other scenarios.
- “Seed photons” is the term for the lower-energy radiation undergoing the energizing process of inverse Compton scattering.
- You may remember the Perseus Cluster from this sonification replicating what a Black Hole sounds like from May 2022.
“While measuring the polarization of 3C 84 was one of the key science goals, we are still searching for additional polarization signals in this galaxy cluster that could be signatures of more exotic physics,” said Steven Ehlert, project scientist for IXPE and astronomer at NASA’s Marshall Space Flight Center in Huntsville.

Arcand“We’ve already determined that for sources like 3C 84, the X-rays originated from inverse Compton scattering,” said Ioannis Liodakis, a researcher at the Institute of Astrophysics – FORTH in Heraklion, Greece, and lead author on the paper. “With IXPE observations of 3C 84 we had a unique chance to determine the properties of the seed photons.”
The first possible origin scenario for the seed photons is known as synchrotron self-Compton, where lower-energy radiation originates from the same jet that produces the highly energetic particles.
In the alternative scenario known as external Compton, seed photons originate from background radiation sources unrelated to the jet.
“The synchrotron self-Compton and external Compton scenarios have very different predictions for their X-ray polarization,” said Frederic Marin, an astrophysicist at the Strasbourg Astronomical Observatory in France and co-author of the study. “Any detection of X-ray polarization from 3C 84 almost decisively rules out the possibility of external Compton as the emission mechanism.”
Throughout the 60-day observation campaign, optical and radio telescopes around the world turned their attention to 3C 84 to further test between the two scenarios.
NASA’s IXPE measured a net polarization of 4% in the X-rays spectrum, with comparable values measured in the optical and radio data. These results strongly favor the synchrotron self-Compton model for the seed photons, where they come from the same jet as the higher-energy particles.
“Separating these two components was essential to this measurement and could not be done by any single X-ray telescope, but by combining the IXPE polarization data with Chandra, NuSTAR, and Swift, we were able to confirm this polarization measurement was associated specifically with 3C 84,” said Sudip Chakraborty, a researcher at the Science and Technology Institute of the Universities Space Research Association in Huntsville, Alabama, and co-author on the paper.
Scientists will continue to analyze IXPE’s data from different locations in the Perseus Cluster for different signals.

NASA Launches Research Program for Students to Explore Big Ideas
NASA is now accepting concepts for a new research challenge. The Opportunities in Research, Business, Innovation, and Technology (ORBIT) challenge is a multi-phase innovation competition designed to empower university and college students to develop next-generation solutions that benefit life on Earth and deep-space exploration.
With up to $380,000 in total prize funding, NASA’s ORBIT challenges student teams to bring their most forward-thinking concepts to the table, either utilizing NASA intellectual property or conceptualizing their own. Teams are tasked with conducting targeted research, designing early mockups or models, and performing feasibility analyses to refine their ideas. Finalists then advance to a live showcase where they present their work to a panel of expert judges, who evaluate the proposals and select winners based on the teams’ final pitches and responses to questions.
The ORBIT has two challenge tracks for teams to choose from. The ORBIT Earth track requires teams to select a NASA-owned patent and develop novel commercial or nonprofit applications addressing real-world problems. From adapting aerospace materials for disaster response and preparedness, to repurposing space-based sensors for healthcare, students must demonstrate clear pathways to public benefit.
The ORBIT Space track asks teams to design new system concepts aligned with NASA’s current and future missions, particularly supporting the Artemis program’s goal of establishing a sustainable human presence on the Moon and preparing for eventual missions to Mars and beyond. Students will create technically feasible designs for everything from lunar habitats that could house future Artemis astronauts to deep space robotics that open more pathways to in-situ resource utilization. Teams that successfully integrate objectives from both tracks may qualify for an optional integration bonus.
This challenge accelerates innovation in areas critical to NASA’s future goals while cultivating a pipeline of interdisciplinary talent. By engaging the next generation in NASA’s dual mission to explore space and improve life on Earth, ORBIT inspires students to join the agency’s talent network while delivering tangible benefits to American communities and industries.
Beyond monetary awards, participants stand to gain mentorship from NASA experts, access to agency facilities, and hands-on experience in systems design, entrepreneurship, and commercialization.

Through Astronaut Eyes: 25 Years of Life in Orbit
After 25 years of continuous human presence in space, the International Space Station remains a training and proving ground for deep space missions, enabling NASA to focus on Artemis missions to the Moon and Mars. The orbiting laboratory is also a living archive of human experience, culture, and connection.
Creating community Expedition 34 crew members pictured in the Unity node of the International Space Station in December 2012. NASAWith 290 visitors from 26 countries and five international partners, the space station has celebrated many different cultures during its 25 years of continuous human presence. Crew members share their holiday traditions, cuisine, music, and games with each other – creating their own community, similar to the ones they have back home, while maintaining a connection to Earth.
Crews living and working aboard the space station during the holiday season have found creative ways to mark the occasions from low Earth orbit. Festive socks, Halloween costumes, mini artificial Christmas trees, champagne, and candle-less menorahs are just a few of the items space station visitors have brought with them to spread holiday cheer.
Mealtimes are also the perfect opportunity to share a taste of home. The space station’s standard menu is inclusive of varied cuisines, but crew members also contribute their own special food items. French astronaut Thomas G. Pesquet once brought macarons to help celebrate his birthday, and several JAXA (Japan Aerospace Exploration Agency) astronauts have hosted sushi parties.
Sharing a piece of themselves and their cultures not only fosters crew camaraderie but also supports the international collaboration necessary to sustain the space station’s success.
Taking music to new heights Expedition 55 crew members aboard the space station (from left) are NASA astronaut Drew Feustel, Roscosmos cosmonaut Oleg Artemyev, and NASA astronauts Ricky Arnold and Scott Tingle. JAXA (Japan Aerospace Exploration Agency)/Norishige KanaiThe first musical instrument, an acoustic guitar, arrived at the orbiting laboratory in August 2001. Since then, playing music aboard the orbiting laboratory has supported astronaut well-being, fostered relationships among international crew members, and helped them connect with home.
The space station’s instrument collection started with an acoustic guitar and an electric keyboard, and also includes an alto saxophone. Some NASA astronauts bring their own instruments to suit their playing habits – bagpipes for Kjell Lindgren, flutes for Catherine Coleman, a piccolo for Jessica Meir. International partners have, too. In April 2010, JAXA astronauts Soichi Noguchi and Naoko Yamazaki performed a duet using a bamboo flute and a miniature version of a traditional Japanese stringed instrument.
Several crew members have played in concerts on Earth while still orbiting the planet. Coleman played a duet with the frontman of Jethro Tull, for example, and ESA (European Space Agency) Luca Parmitano used the station’s electric keyboard to participate in a concert at Moscow’s Luzhniki Stadium. He later became the first person to perform a DJ set from space.
The space station has even hosted at least one epic jam session, featuring the crew members of Expedition 55 on guitar, flutes, and a drum made from a repurposed waste container.

An astronaut’s perspective The sun shines above Earth’s horizon as the space station orbited 264 miles above the Canadian province of Quebec.NASAAcross the decades and missions of U.S. human spaceflight, NASA astronauts have shared a unique and transcendent experience: looking down at Earth from the space station’s cupola windows. That experience has had a profound impact on many, creating a powerful shift in the way astronauts think about life and our home planet – a phenomenon known as the overview effect.
Crew members aboard the orbital outpost describe the beauty of our planet and how it stands in stark contrast to the darkness of space from the cupola module. Many comment on Earth’s fragility and the need to protect it after observing how thin the planet’s atmosphere appears to be from orbit. Others note the lack of borders or lines we see on a map, emphasizing that all of humanity is connected.
Regardless of how long they stay in orbit, astronauts return with a different worldview they are eager to share with others.

Capturing the beauty and science in orbitThe space station provides a vantage point like no other. The cupola observation module, with its seven windows, offers unparalleled panoramic views of Earth and space which are crucial for monitoring mission activities, conducting scientific observations, and supporting crew morale and habitability. Astronauts aboard the orbiting laboratory have captured millions of photographs of Earth, creating a visual archive that spans 25 years of continuous human presence in orbit.
These images serve as scientific data used to track hurricanes, monitor wildfires, measure glacial retreat, and study urban growth through NASA’s Crew Earth Observations. Astronaut photography also supports NASA Disaster Response, a program that works with various NASA centers to collect data before, during, and following a disaster to aid recovery efforts.
The cupola has become a favorite spot for astronauts to work and reflect. Their photos help connect people worldwide to the orbital outpost, reinforcing the importance of protecting our planet.

Station memories from the ground Flight controllers at NASA’s Mission Control Center in Houston marked 25 years of continuous human presence in space with the Expedition 73 crew aboard the orbital outpost on Nov. 2, 2025.NASA/Pooja J. JesraniBehind every moment aboard the orbiting laboratory is a dedicated team on the ground – engineers, scientists, flight directors, and communicators – who work around the clock to keep crews safe and missions running smoothly.
They mark milestones together, from spacecraft dockings and crew returns to mission anniversaries and plaque-hanging ceremonies. Teams on console in the mission control have even organized chess matches with astronauts in orbit to foster connection between Earth and space.
The flight control team celebrated the 25th anniversary of continuous human habitation in space with the Expedition 73 crew aboard the station on Nov. 2, 2025. The team congratulated the crew to mark the incredible milestone. They emphasized that humanity has held a heartbeat in orbit for a quarter century, a testament to human curiosity, cooperation, and courage that keeps the light of exploration shining above Earth and represents the very best of what humankind can achieve together. Every orbit, every experiment, and every challenge has taught teams how to adapt, grow, and build the skills needed for the next great leaps to the Moon, Mars, and beyond.
Holidays are often spent in the control rooms, where teams decorate consoles, share potluck meals, and hold the occasional cookie-cutting contest. Engineers in the station’s Mission Evaluation Room (MER) host an annual “MERloween,” a tradition that began in 2006 to celebrate the year’s milestones and reflect on lessons learned.
These traditions highlight the spirit and teamwork that make every mission possible. The dedication honed through decades of mission support now guides the teamwork and expertise that will send Artemis astronauts to the Moon and beyond.
Flight controllers in mission control celebrate the holidays while supporting crews aboard the space station.

NASAFormer NASA astronaut Nicole Stott became the first person to watercolor in space during her time aboard the orbiting laboratory. Inspired by the beauty of Earth from orbit, she used her art to connect the science of human spaceflight with the creativity that defines it.
After returning to Earth, Stott helped launch the Space for Art Foundation, which unites children around the world through the healing power of art and space. One of its most meaningful initiatives, the Spacesuit Art Project, invites young patients undergoing cancer treatment to create colorful artwork that is transformed into custom-made spacesuits. Each suit – Hope, Courage, Unity, Victory, Dreamer, Exploration, Beyond, and Infinity – celebrates the imagination and resilience of its creators.
Four of these suits have journeyed to and from the orbiting laboratory, where astronauts wore them during special downlinks to speak with the patients and raise awareness for childhood cancer research. The project shows that space exploration is not only about discovery, but about compassion, creativity, and the human spirit that connects us all.

Article 1 week agoNASA Ignites New Golden Age of Exploration, Innovation in 2025
With a second Trump Administration at the helm in 2025, NASA marked significant progress toward the Artemis II test flight early next year, which is the first crewed mission around the Moon in more than 50 years, as well as built upon its momentum toward a human return to the lunar surface in preparation to send the first astronauts — Americans — to Mars.
As part of the agency’s Golden Age of innovation and exploration, NASA and its partners landed two robotic science missions on the Moon; garnered more signatories for the Artemis Accords with 59 nations now agreeing to safe, transparent, and responsible lunar exploration; as well as advanced a variety of medical and technological experiments for long-duration space missions like hand-held X-ray equipment and navigation capabilities.
NASA also led a variety of science discoveries, including launching a joint satellite mission with India to regularly monitor Earth’s land and ice-covered surfaces, as well as identifying and tracking the third interstellar object in our solar system; achieved 25 continuous years of human presence aboard the International Space Station; and, for the first time, flew a test flight of the agency’s X-59 supersonic plane that will help revolutionize air travel.
Sean Duffy, named by President Trump, is serving as the acting administrator while NASA awaits confirmation of Jared Isaacman to lead the agency. Isaacman’s nomination hearing took place in early December, and his nomination was passed out of committee with bipartisan support. The full Senate will consider Isaacman’s nomination soon. President Trump also nominated Matt Anderson to serve as deputy administrator, and Greg Autry to serve as chief financial officer, both of whom are awaiting confirmation hearings. NASA named Amit Kshatriya to associate administrator, the agency’s highest-ranking civil servant position.
Key accomplishments by NASA in 2025 include:
Astronauts exploring Moon, Mars is on horizon
Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build upon our foundation for the first crewed mission to Mars. The Artemis II test flight is the first flight with crew under NASA’s Artemis campaign and is slated to launch in early 2026. The mission will help confirm systems and hardware for future lunar missions, including Artemis III’s astronaut lunar landing.
NASA also introduced 10 new astronaut candidates in September, selected from more than 8,000 applicants. The class is undertaking nearly two years of training for future missions to low Earth orbit, the Moon, and Mars.
Progress to send the first crews around the Moon and on the lunar surface under Artemis includes:
- NASA completed stacking of its Space Launch System rocket and Orion spacecraft for Artemis II. Teams integrated elements manufactured across the country at NASA’s Kennedy Space Center in Florida, including the rocket’s boosters and core stage, as well as Orion’s stage adapter and launch abort system, to name a few.
- Ahead of America’s 250th birthday next year, the SLS rocket’s twin-pair of solid rocket boosters showcases the America 250 emblem.
- The Artemis II crew participated in more than 30 mission simulations alongside teams on the ground, ensuring the crew and launch, flight, and recovery teams are prepared for any situation that may arise during the test flight. Soon, crew will don their survival suits and get strapped into Orion during a countdown demonstration test, serving as a dress rehearsal for launch day.
- The agency worked with the Department of War to conduct a week-long underway recovery test in preparation to safely collect the Artemis II astronauts after they splashdown following their mission.
- To support later missions, teams conducted a booster firing test for future rocket generations, verified new RS-25 engines, test-fired a new hybrid rocket motor to help engineering teams better understand the physics of rocket exhaust and lunar landers, as well using various mockups to test landing capabilities in various lighting conditions. Teams also conducted human-in-the-loop testing in Japan with JAXA (Japan Aerospace Exploration Agency) with a rover mockup from their agency.
- NASA also continued work with Axiom Space, to develop and test the company’s spacesuit, including completing a test run at the Neutral Buoyancy Laboratory at NASA Johnson ahead of using the suit for Artemis training. The spacesuit will be worn by Artemis astronauts during the Artemis III mission to the lunar South Pole.
- On the Moon, future crew will use a lunar terrain vehicle, or LTV, to travel away from their landing zone. NASA previously awarded three companies feasibility studies for developing LTV, followed by a request for proposals earlier this year. The agency is expected to make an award soon to develop, deliver, and demonstrate LTV on the lunar surface later this decade. The agency also selected two science instruments that will be included on the LTV to study the Moon’s surface composition and scout for potential resources.
- For operations around the Moon, NASA and its partners continued to develop Gateway to support missions between lunar orbit and the Moon’s surface. Construction and production of the first two elements, a power and propulsion system and habitation element, each progressed, as did development and testing of potential science and technology demonstrations operated from Gateway. International partners also continued work that may contribute technology to support those elements, as well as additional habitation capabilities and an airlock.
- This past year, NASA’s Lunar Surface Innovation Consortium team collaborated with over 3,900 members from academia, industry, and government on key lunar surface capabilities. Members from across the U.S. and 71 countries participated in two biannual meetings, three lunar surface workshops, and monthly topic meetings, resulting in 10 studies, four reports, and nine conference presentations.
Building on previous missions and planning for the future, NASA will conduct more science and technology demonstrations on and around the Moon than ever before. Work toward effort included:
- Selected a suite of science studies for the Artemis II mission, including studies that focus on astronauts’ health.
- Launched two CLPS (Commercial Lunar Payload Services) flights with NASA as a key customer, including Firefly’s Blue Ghost Mission One, which landed on the Moon March 2, and Intuitive Machines’ Nova C lunar lander, which touched down on March 6.
- Experiments and tech demos aboard these flights included an electrodynamic dust shield, lunar navigation system, high-performance computing, collection of more than 9,000 first-of-a-kind images of the lunar lander’s engine plumes, and more.
- For future CLPS flights, NASA awarded Blue Origin a task order with an option to deliver the agency’s VIPER (Volatiles Investigating Polar Exploration Rover) to the lunar South Pole in late 2027, as well as awarded Firefly another flight, slated for 2030.
- Teams studied regolith (lunar dirt and rocks) in a simulated lunar gravity environment and tested how solid materials catch fire in space.
- The agency’s 55-pound CubeSat in lunar orbit, CAPSTONE, exceeded 1,000 days in space, serving as a testbed for autonomous navigation and in-space communications.
- Published findings from this Artemis I experiment highlighting why green algae may be a very good deep space travel companion.
Technological and scientific steps toward humanity’s next giant leap on the Red Planet include:
- Launched a pair of spacecraft, known as ESCAPADE, on a mission to Mars, arriving in September 2027, to study how its magnetic environment is impacted by the Sun. This data will better inform our understanding of space weather, which is important to help minimize the effects of radiation for future missions with crew.
- NASA announced Steve Sinacore, from the agency’s Glenn Research Center in Cleveland, to lead the nation’s fission surface power efforts.
- Selected participants for a second yearlong ground-based simulation of a human mission to Mars, which began in October, as well as tested a new deep space inflatable habitat concept.
- Completed the agency’s Deep Space Optical Communications experiment, which exceeded all of its technical goals after two years. This type of laser communications has the potential to support high-bandwidth connections for long duration crewed missions in deep space.
- NASA completed its fourth Entry Descent and Landing technology test in three months, accelerating innovation to achieve precision landings on Mars’ thin atmosphere and rugged terrain.
- Other research to support long-duration missions in deep space include how fluids behave in space, farming space crops, and quantum research.
Through the Artemis Accords, seven new nations have joined the United States, led by NASA and the U.S. Department of State, in a voluntary commitment to the safe, transparent, and responsible exploration of the Moon, Mars, and beyond. With nearly 60 signatories, more countries are expected to sign in the coming months and years.
- New nations joining America, a founding member in 2020, in signing the accords this year included Bangladesh, Finland, Norway, and Senegal, as well as Hungary, Malaysia, and the Philippines.
- A NASA delegation participated in the 76th International Astronautical Congress in Sydney, Australia. During the congress, NASA co-chaired the Artemis Accords Principals’ Meeting, bringing together dozens of nations furthering discussions on their implementation.
Finally, NASA engaged the public to join its missions to the Moon and Mars through a variety of activities. The agency sought names from people around the world to fly their name on a SD card aboard Orion during the Artemis II mission. NASA also sponsored a global challenge to design the spacecraft’s zero gravity indicator, announcing 25 finalists this year for the mascot design. Artemis II crew members are expected to announce a winner soon.

- The agency also continues to support the design and development of space stations and technologies through agreements with Northrop Grumman, Sierra Space, SpaceX, Special Aerospace Services, and ThinkOrbital.
Pioneering aviation research
This year saw a major triumph for NASA’s aviation researchers, as its X-59 one-of-a-kind quiet supersonic aircraft made its historic first flight Oct 28. NASA test pilot Nils Larson flew the X-59 for 67 minutes up to an altitude of about 12,000 feet and an approximate top speed of 230 mph, precisely as planned. The flight capped off a year of engine testing including afterburner testing, taxi testing, and simulated flights from the ground — all to make sure first flight went safely and smoothly. The X-59 team will now focus on preparing for a series of flight tests where the aircraft will operate at higher altitudes and supersonic speeds. This flight test phase will ensure the X-59 meets performance and safety expectations. NASA’s Quesst mission also began testing the technologies that they will use to measure the X-59’s unique shock waves and study its acoustics during future mission phases.
Researchers also made other major strides to further aviation technologies that will benefit the public and first responders, including live flight testing of a new portable airspace management system with the potential to greatly improve air traffic awareness during wildland fire operations.
During the past year, the agency’s aeronautics researchers also:
- Conducted live flight testing with aircraft performing simulated wildland fire response using NASA’s new portable airspace management system known as Advanced Capabilities for Emergency Response Operations (ACERO) project.
- Used NASA’s Transonic Dynamics Tunnel in Virginia to test the performance of rotors designed for NASA’s Dragonfly rotorcraft, which will explore Saturn’s moon, Titan.
- Performed wind tunnel tests to see how icing could affect longer, thinner wings on future airliners and to evaluate a tiltwing design likely to see wide usage in advanced air mobility vehicles.
- Tested NASA-designed ultralight aerogel antennas that could be embedded into aircraft skin for more aerodynamic, reliable, satellite communications.
- Worked to advance the airborne transportation of people and goods, including a collaboration with the Department of War to advance capabilities for long-distance cargo drones; a partnership to test a tool for remotely piloted urban air transportation; flight tests with partners exploring large-scale drone cargo flights; and work with ResilienX to enhance preflight planning for safer future skies.
- Performed research to help with the integration of air taxis and similar future aircraft, such as producing real-world data to help understand their flight dynamics; dropping a full-scale fuselage model to test its materials upon impact; collecting to evaluate strategies for urban airspace integration; investigating passenger comfort; and testing 5G-based aviation network technology to boost air taxi connectivity. Evaluated a system that would help prevent collisions between air taxis and other future aircraft in urban environments.
- Made advances to unsteady pressure sensitive paint wind tunnel technology, allowing it to measure air pressure on miniature aircraft and rocket models 10,000 times faster with 1,000 times higher resolution.
- Collected data on mixed reality systems that allow users to interact with physical flight simulators while wearing virtual reality headsets.
- Developed the GlennICE tool for U.S. researchers and aircraft developers to integrate icing-related considerations into aircraft design.
- Supported research for safer and smoother airline and airport operations, including; developing a preflight rerouting tool to actively curb commercial airline delays and save fuel; demonstrating a unique air traffic management concept for safer aircraft operate at higher altitudes; and hosting technology testing to make runway taxiing safer and more efficient.
- Adapted technology that can measure temperature and strain on high-speed air vehicles for hypersonic flights at speeds greater than Mach 5.
- Provided funding for 14 university teams to build innovative new compact emergency response aircraft; issued new awards for university teams to participate in real-world aviation challenges, including the program’s first to a community college. NASA also named winners in the 2025 Gateways to Blue Skies competition, as well as selected new student teams for the University Leadership Initiative.
