This is How NASA Flight Tests New Technology
Flight tests are a big part of how NASA turns breakthrough ideas into reality. From flying humans faster than the speed of sound to proving designs that helped shape the space shuttle, flight testing transforms bold concepts into safer, more efficient technologies that benefit the public.
“Flight tests are a way to safely and effectively prove new technology, which helps certification authorities certify equipment,” said Wayne Ringelberg, chief pilot at NASA’s Armstrong Flight Research Center in Edwards, California. “It helps industry iterate and make systems better, and it promotes research in areas where new ideas can be developed.”
For nearly 80 years, teams at NASA Armstrong have used flight testing in the Southern California desert to push the limits of aerodynamics and advance aviation. Thanks to that work, NASA-developed innovations are aboard every U.S. commercial aircraft and inside every control tower today.
“The space side of NASA uses flight test, too. Every mission, like Artemis II, is never routine,” Ringelberg said. “Everything we’re doing when flying a test mission is something new or different.”
NASA test pilots Jim Less, left, and Nils Larson walk away from a hangar at NASA’s Armstrong Flight Research Center in Edwards, California, on Thursday, Feb. 4, 2026. The pilots support the agency’s Crossflow Attenuated Natural Laminar Flow (CATNLF) project, which aims to lower fuel costs for future commercial aircraft by testing a scale-model wing designed to improve laminar flow.NASA/Christopher LC ClarkEvery NASA test flight — whether it’s studying new software, hardware, or the revolutionary technology of an experimental X-plane — relies on engineers, researchers, pilots, maintenance crew, control room operators, and many others working together.
“Experienced operators and engineers evaluate how things work in flight,” Ringelberg said. “Most new technologies are designed to work in a lab or can be tested in a wind tunnel or other facility, but you never really know how they’ll perform until you fly them.”
Preflight tests often include computer analysis, simulation, wind tunnel testing, and ground tests focused on an aircraft’s ability to withstand the forces of flight and the environments through which it may fly. After hardware or software is deemed safe to fly, researchers turn the mission over to the flight test team.
To support testing, NASA Armstrong maintains an aircraft fleet modified to create space for new hardware or instruments, as well as the ability to integrate new software. These aircraft are flying laboratories, and pilots are trained to accomplish experimental missions.
An F-15 research aircraft sits on the ramp at NASA’s Armstrong Flight Research Center in Edwards, California, on Tuesday, March 17, 2026. NASA pilots Jim Less, front seat, and Carrie Worth prepare for the flight. The agency’s Crossflow Attenuated Natural Laminar Flow (CATNLF) test article is attached to the bottom of the F-15. The project aims to lower fuel costs for future commercial aircraft by testing a scale-model wing designed to improve laminar flow.NASA/Carla EscamillaFor example, flight testing recently helped NASA gather critical data on laminar flow, or the smooth flow of air, over a wing. The work could lower fuel costs for future airliners. Computer modeling, wind tunnel tests, and other methods helped advance the research, but to find out even more about how the wing concept could reduce drag for future airliners, NASA used a scale model in actual flight.
NASA researchers strapped the Crossflow Attenuated Natural Laminar Flow (CATNLF) model wing to the belly of one of NASA Armstrong’s F-15s. The arrangement allowed them to collect all the information they would need without doing the extensive, costly modifications required to install a full-scale wing on an aircraft.
After a flight series is complete, engineers and researchers analyze the data. Did the instrument work as designed? Did the experimental aircraft perform safely at a high altitude? Did the software operate as planned? Each test raises its own set of questions to evaluate.
NASA continues working with academia, the Department of War, and industry partners to advance U.S. aviation through flight test and bring new benefits to the flying public.

Jason Peterson’s responsibilities for NASA’s Artemis II mission went beyond his usual role as the range operations manager at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
For Peterson, working at NASA is a surreal full-circle moment.
“I grew up in DeLisle, Mississippi, right down the road from NASA,” said Peterson. “You would hear NASA testing, the windows would shake, and you knew they were out there. Not in a million years would I have ever dreamed I would work with NASA.”
His career journey took a few turns before reaching the space agency.
“I got out of school, welded, went to college and then to the Air Force. The path to NASA really started to develop from there,” said Peterson.
Peterson spent 24 years in the U.S. Air Force and Air National Guard, working in airfield and air-to-ground range operations, followed by a few years working as an aircraft dispatcher at Airbus Final Assembly Line.
Peterson credits his military experience with preparing him for the 12-to-16-hour workdays that helped bring the Artemis II test flight around the Moon and into view for audiences around the world.
He supported the team responsible for delivering video and communication feeds for the launch of NASA’s SLS (Space Launch System) rocket with the Artemis II crew aboard the Orion spacecraft, and then splashdown in the Pacific Ocean.
During the nearly 10-day mission, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth.
Aboard the USS John P. Murtha, Peterson was the first on the ship to spot the capsule returning with the crew.
“The sonic boom was the moment it truly hit me. Even though I was tracking the capsule, it did not fully register until then. Chills went down my neck and back. You realize our astronauts are coming home. It was an incredible and emotional moment.”JASON PETERSON
Range Operations Manager for NASA Stennis
Jason Peterson, NASA Stennis range operations manager, is shown with the Orion spacecraft aboard the USS John P. Murtha on April 13, 2026. Peterson was the first to spot the capsule returning with the Artemis II crew as he supported the team responsible for delivering video and communication feeds during splashdown operations. Credits: NASANASAPeterson operated one of six cameras providing live coverage by using a high‑resolution, multi‑sensor system with thermal capabilities. Using the ship’s heading and Orion’s predicted trajectory, he located the capsule within minutes and began tracking it.
Orion entered Earth’s atmosphere at about 400,000 feet above the planet’s surface, traveling nearly 35 times the speed of sound and about 1,956 statute miles from its splashdown point off the coast of California. Peterson tracked Orion from the release of the small parachutes that first slow and steady the capsule, through the main parachutes opening, and all the way to splashdown.
“You are fully locked in, keeping it centered, in focus, and steady,” said Peterson.
Peterson’s focus on the mission began weeks earlier at NASA’s Kennedy Space Center in Florida.
In the days leading to launch, Peterson worked with the team running full systems checks, staging communications gear, and preparing drones and fixed‑wing camera assets. He helped configure and operate the systems that ensured live video flowed from the launch pad, the crowds, and surrounding air and ground platforms.
On April 1, the launch day of Artemis II, the team unloaded and set up high‑resolution sensors, connection terminals, routers, monitors, fiber lines, and drone equipment. They flew drones to capture crowd scenes and aerial views before liftoff.
As the SLS rocket launched, Peterson’s full attention was on positioning the drone and maintaining the shot.
“There is not much time to step back and take in the moment, as you are concentrating on precision,” said Peterson.
As the mission got underway, Peterson and the team packed up, returned to the facility, and downloaded the day’s footage.
The Artemis II crew were more than halfway to the Moon as Peterson arrived in San Diego on April 4. In the days leading to splashdown, the team loaded and installed high‑fidelity cameras and supporting equipment, all to help the world witness a historic milestone when the Artemis II crew returned to Earth on April 10.
Next up will be Artemis III. NASA will launch four astronauts from NASA Kennedy aboard the Orion spacecraft on the SLS rocket. Building on the successful Artemis II crewed test flight in April, Artemis III will pave the way for future surface missions, with experts like Peterson helping every step of the way.

Astronomers using NASA’s Hubble Space Telescope have found something they never expected — ultraviolet light from a galaxy that existed just 1.4 billion years after the big bang. That galaxy contains tightly clustered young stars that produce ionizing light capable of transforming the opaque, neutral gas within and immediately around the galaxy, clearing our view. This suggests that similar galaxies in the early universe were responsible for clearing the neutral fog of hydrogen gas that once filled the cosmos.
A paper describing this discovery was published June 23 in the Astrophysical Journal.
The galaxy, cataloged MXDFz4.4, existed at the end of the Era of Reionization, a transformative period in our universe. During roughly the first billion years of the cosmos, the gas between stars and galaxies was opaque to energetic ultraviolet light. As time wore on, gas everywhere became transparent or ionized. The changeover was not like an on/off switch, but likely took hundreds of millions of years. Researchers are still collecting evidence to fully understand how this happened, which is why MXDFz4.4 sets a critical precedent.
“Observing a galaxy like this was thought to be impossible,” said lead author Ilias Goovaerts, a postdoctoral fellow at the Space Telescope Science Institute (STScI) in Baltimore. “Researchers expected the ‘fog’ or neutral hydrogen that filled the early universe would be too thick and obscure our view of its ionizing light. Hubble not only spotted that light, but it also helped reveal incredible details about the galaxy’s characteristics.”
Detailed visible-light images from Hubble reveal that several bursts of younger stars cleared the space in and around galaxy MXDFz4.4. Astronomers have long sought evidence to explain this transition — and Hubble has provided the first example in this time period. Image: NASA, ESA, CSA, STScI, Ilias Goovaerts (STScI), Marc Rafelski (STScI, JHU), Anton Koekemoer (STScI); Image Processing: Alyssa Pagan (STScI) Great light ‘escape’Young, massive stars emit ultraviolet light capable of ionizing hydrogen atoms. As this light traveled for over 12 billion years to reach Hubble, space expanded, and the light stretched or redshifted into visible light. Hubble’s wavelength coverage, combined with the sensitivity and resolution of its space-based vantage point, makes it the only telescope capable of capturing this ultraviolet light from the early universe.
“Astronomers have found many galaxies that existed at this point in the history of the universe, but we haven’t detected ionizing photons from any of them, making MXDFz4.4 one of a kind,” said Marc Rafelski, a co-author and Hubble deputy mission head at STScI.
Hubble’s long exposures, pulled from several existing surveys, revealed that the galaxy’s young, massive stars are the source of the ultraviolet light, which cleared the surrounding space. These stars formed in bursts within the last few million years of MXDFz4.4’s existence and are crammed together.
Amplifying this crowding effect, MXDFz4.4 is about 100 times smaller by area than our Milky Way galaxy, but is forming stars 10 times faster.
“A lot of young, hot, massive stars in a small space do a better job of blasting through opaque gas,” Goovaerts said. The researchers estimate that 50 to 100% of the young stars’ energetic ionizing light is escaping the surrounding gas.
Massive stars’ lifetimes also play a role, since they live for only a few million years. Many explode as supernovae, releasing gigantic amounts of energy and blowing colossal holes that allow even more light to escape.
This illustration portrays galaxy MXDFz4.4 when it existed 1.4 billion years after the big bang. At this time, the universe was still a mix of opaque and transparent gas as the Era of Reionization was gradually ending. Illustration: NASA, ESA, Leah Hustak (STScI) Partnering with other observatoriesHubble could not do this alone. These conclusions are supported by survey data taken by NASA’s James Webb Space Telescope in near-infrared light and the MUSE eXtremely Deep Field or MXDF, the galaxy’s namesake, captured by the European Southern Observatory’s Very Large Telescope (VLT) in visible light.
The team used Webb’s data to determine the galaxy’s mass, analyze its older stars, and measure the galaxy’s star formation history. The galaxy’s older stars are less massive and cooler, and therefore not responsible for changing the gas around them.
Comparing Hubble and Webb data also showed that recent star formation happened in bursts. “Without Webb to clarify what we saw in Hubble’s images, we couldn’t make these conclusions,” Rafelski said.
Data from the VLT pinpointed when MXDFz4.4 existed: 1.4 billion years after the big bang. Before this discovery, researchers had only identified a galaxy emitting ionized light from a time when the universe was 1.6 billion years old. Only a few additional examples have been identified, and those existed when the universe was about 2 billion years old. MXDFz4.4 brings researchers closer to drawing firm conclusions about how the Era of Reionization unfolded.
Credit: NASA’s Goddard Space Flight Center; Lead Producer: Paul Morris Expanding what we knowStudying the Era of Reionization is a decades-old endeavor. Researchers use statistics about star populations in nearby galaxies, which we can observe in great detail, to make well-informed assumptions about what might be happening in galaxies in the early universe, in part because their star populations are too distant to resolve in any detail.
In 2023, researchers using Webb showed that galaxies’ stars emitted enough light to heat and ionize the gas around them 900 million years after the big bang. This was a breakthrough, but astronomers need galaxies like MXDFz4.4 to fully explain how the process happened, since it shows how the high-energy light from young stars managed to escape the gas and dust within the galaxy itself.
It’s possible other galaxies like MXDFz4.4 are waiting to be discovered.
“Hubble’s observations of MXDFz4.4 let us test our hypotheses much closer to the Era of Reionization than ever before,” Rafelski said. “Finding more galaxies, especially at slightly later cosmic times where larger samples are within reach, would let us refine these measurements and figure out what cleared our view as that era was ending.”
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Located 12 million light-years away and undergoing rapid star formation, edge-on spiral galaxy Messier 82 (M82) is a scientifically unique sight to behold, and now NASA’s James Webb Space Telescope has revealed previously unseen details.
M82’s intense star formation, thought to be the result of a galaxy merger, will be a short-lived event in astronomical terms, estimated to last a few hundred million years in its entirety. This temporary phase of extreme star formation relative to the galaxy’s mass, as well as its location in the local universe, are among the factors that make M82, also known as the Cigar galaxy, a one-of-a-kind environment to study.

This Webb and Hubble composite image includes 16.5 million stars (blue-white), dust grains (red-orange), and ionized hydrogen gas (yellow). Image: NASA, ESA, CSA, Adam Smercina (STScI, Tufts), Thomas Williams (University of Manchester); Image Processing: Alyssa Pagan (STScI)A team of astronomers recently completed an imaging survey with the Webb telescope. This program entailed a total of 65 hours of observation time with Webb’s NIRCam (Near-Infrared Camera) instrument and revealed never-seen-before details of the starburst galaxy, including its distended disk structure and millions of individual stars. Webb’s high-resolution imaging, specifically of the main plane of the galactic disk, has unlocked vital information for astronomers as they seek to uncover M82’s formation history. Additionally, the Webb data will help scientists understand the current processes occurring within the starburst galaxy.
“M82 is a mess, but it’s a beautiful mess. We don’t fully understand what’s going on, especially concerning its evolutionary history. What could have triggered such an elevated rate of star formation? How long has this galaxy been driving plumes of material away from its center?” said principal investigator Adam Smercina, a NASA Hubble Fellow at the Space Telescope Science Institute in Baltimore, and incoming Assistant Professor at Tufts University in Massachusetts. “M82 is an ideal galaxy evolution laboratory because it has properties that allow us to probe important physical processes, such as how stars form in such environments and how that activity drives outflows. M82 provides a simultaneous window onto many astrophysical questions, in a way that no other galaxy in the local universe can.”

Image: NASA, ESA, CSA, Adam Smercina (STScI, Tufts), Thomas Williams (University of Manchester); Image Processing: Alyssa Pagan (STScI)Prior to Webb, many observatories looked at the starburst galaxy, including NASA’s Hubble and retired Spitzer space telescopes. However, the sheer volume of dust within that galaxy limited the amount of information astronomers could acquire on M82 at high resolution. While Webb has previously looked at this galaxy, the duration of the new imaging survey, combined with the telescope’s infrared sensitivity, enabled it to pierce through the thick dust.

Hubble detailed M82’s gas and dust structure, while Webb pierced through the dust and resolved millions of stars in infrared light. Image: NASA, ESA, CSA, Adam Smercina (STScI, Tufts), Thomas Williams (University of Manchester); Image Processing: Alyssa Pagan (STScI)The telescope’s near-infrared-light view is a snapshot of a scene that has been evolving over a couple hundred million years. Webb’s image contains approximately 16.5 million individual stars dispersed throughout the galaxy. The light from these stellar sources is depicted as luminous blue granules. This is only a small portion of the total amount of stars astronomers think reside in a galaxy like M82, with the majority too faint to be seen.
“The sheer number of stars that we were able to resolve with Webb is incredible,” said team member Benjamin Williams of the University of Washington. “It’s a whole different world from what we’ve been able to see with other telescopes. All of these stars collectively provide a detailed fossil record of the formation and evolution of M82.”
Moving inward, the increase in brightness and the asymmetrical shape of the galactic disk hints at the spiral galaxy’s unique underlying structure. The differing radii between the two sides suggests that M82 has a distorted shape, which can happen during intense galaxy mergers.
“At first glance, the disk of the galaxy may seem less spectacular because Webb sees through the dust,” said team member Eric Bell of the University of Michigan. “But M82 is a delightfully complex system. Webb’s observations will help us address some ongoing mysteries, such as how star formation has moved within M82 over the last few billion years.”

Because of the extreme star formation within the galaxy, which is 10 times faster than the Milky Way galaxy’s star formation rate, stellar birth will eventually be disrupted. M82’s stellar frenzy is causing bipolar plumes of material to be ejected above and below the disk. Though it looks like a tumultuous region, the hourglass-shaped outflows appear to have a layered structure. The yellow tendrils of material closest to the galaxy’s disk represent ionized gas, whereas the orange material farther away depicts small dust grains. These grains are called polycyclic aromatic hydrocarbons and are helpful in tracing material in the space between the galaxy’s stars, also known as the interstellar medium.
The information collected as part of this Webb study is just one dataset scientists will analyze as they seek to piece together this starburst galaxy’s formation history.
“Galaxies are such intricate ecosystems that if you truly want to understand them, you have to pull datasets from different missions together,” said team member Kristen McQuinn of the Space Telescope Science Institute. “One mission cannot fully answer all of the questions we have about M82. Combining the data collected by different telescopes, like Webb and Hubble, is powerful. When you marry the datasets, you expand what you can probe, and the questions that you can pose are even more complex.”
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

NASA Sounding Rocket to Launch Student Experiments
3 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater)NASA’s Wallops Flight Facility in Virginia is scheduled to launch a sounding rocket carrying student-developed experiments for the agency’s RockSatX and RockOn programs Wednesday, June 24, between 5:30 and 9:30 a.m. EDT, with a backup day on Thursday, June 25.
Students watch as their experiments launch aboard a sounding rocket for the RockSat-X program from NASA’s Wallops Flight Facility Aug. 11, 2022, at 6:09 p.m. EDT. The Terrier-Improved Malemute rocket carried the experiments to an altitude of 99 miles before descending via a parachute and landing in the Atlantic Ocean.NASA Wallops/Terry ZaperachThe RockSat and RockOn programs provide technical training and hands-on experiences that prepare and equip students to enter the United States aerospace industry. For the first time, NASA will combine both the RockSat and RockOn missions into one rocket, which will carry experiments developed by nearly 250 participants from 38 university and community college teams.
“The challenge was finding ways to fit as many experiments onto one sounding rocket as we could,” said Victoria Stoffel, workforce development lead at NASA Wallops. “The Sounding Rocket Program Office team found creative ways to fit nearly 50 experiments into one rocket. We are grateful to the Wallops teams for making this happen for the students to get the most from this experience.”
The RockOn teams work together to build their experiment onsite, getting hands-on experience putting together a circuit board from scratch and launching it into space. The more advanced RockSat program teams design and build their experiments, going through design reviews modeled on larger NASA missions. Each team can experience what it’s like working on a real NASA mission, from development to launch.
The RockSat student experiments range from taking measurements of weather and radiation in Earth’s upper atmosphere to testing technologies, such as heat shields, space-debris tracking, and robotic servicing, that could help future NASA missions.
The Terrier-Improved Malemute suborbital sounding rocket, which will carry the experiments, is expected to reach an altitude of about 100 miles before descending by parachute into the Atlantic Ocean to be recovered. The launch may be visible in the Chesapeake Bay region.

NASA’s Chandra Finds Possible Supernova Remnant
Using data from NASA’s Chandra X-ray Observatory, astronomers may have found a supernova remnant – seen in this June 11, 2026, image – in an intriguing neighborhood in the middle of the Milky Way galaxy. Supernova remnants are the expanding remains of exploded stars and provide elements like iron, oxygen, and silicon that are critical for the formation of planets and for life as we know it to form and flourish.
This new supernova remnant, if confirmed, would be one of the closest ever discovered to the supermassive black hole at the central region of our home galaxy, an exotic region crammed with massive stars, long threads of magnetic fields and dense clouds of gas orbiting rapidly around the Galactic Center.

Media joining by phone should request dial‑in details by the same deadline. To ask a question, media must dial in no later than 15 minutes before the start of the news conference.
Tuesday, June 30
NASA astronauts Chris Williams and Jessica Meir will exit the station’s Quest airlock to replace a wrist joint that malfunctioned during normal Canadarm2 operations on May 27 after the arm drew elevated motor current and did not move as expected.
Watch NASA’s live U.S. spacewalk 95 coverage beginning at 7 a.m. EDT on NASA+, Amazon Prime, Netflix, and the agency’s YouTube channel. The spacewalk is expected to last roughly six-and-a-half hours.
NASA worked alongside CSA to understand the issue and determined a spacewalk was required to replace the joint using a spare already aboard the space station. Repairs to robotics, like Canadarm2, are normal and expected after more than 25 years of continuous operations, as the system was designed with replaceable components and planned maintenance in mind.
This spacewalk will be the second for Williams and the fifth for Meir. Williams will serve as spacewalk crew member 1 and will wear a suit with red stripes. Meir will serve as crew member 2 and will wear an unmarked suit. It will be the 280th spacewalk in support of space station assembly, maintenance, and upgrades.

NASA’s Webb Finds Clues to Ancient, Distant Origin of Comet 3I/ATLAS

As interstellar comet 3I/ATLAS began moving away from the Sun in December 2025, astronomers took the opportunity to turn NASA’s powerful James Webb Space Telescope in its direction and capture detailed measurements of its chemical components. The comet was freshly warmed from its closest pass by the Sun, and its ancient ice had been converted to a bright coma of gas ideal for observation.
Webb captured detailed data, including chemical ratios of carbon and deuterium, also known as heavy hydrogen, that are not found in solar system comets. The results surprised researchers. Working backward, astronomers used the components that make up comet 3I/ATLAS to understand the environment in which it formed.
A paper detailing the findings published June 22 in the journal Nature.
Image: Interstellar Comet 3I/ATLAS (NIRSpec IFU) Researchers used the NIRSpec (Near-Infrared Spectrograph) instrument on NASA’s James Webb Space Telescope to map specific chemical contents of comet 3I/ATLAS as it moved away from the Sun. Image: NASA, ESA, CSA, STScI, Martin Cordiner (CUA, NASA-GSFC); Image Processing: Alyssa Pagan (STScI)The comet’s name comes from its status as the third confirmed interstellar comet, meaning it originated outside the solar system, and the telescope that first spotted it, the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System).
“This was a unique opportunity to study an ancient object from the distant galaxy, probably pre-dating our Sun and solar system,” said astro-chemist Martin Cordiner of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study. “On the one hand, we get direct insight into that distant time and place, and on the other, we learn something about how unusual our own solar system may be.”
Cordiner and the research team joined astronomers from many sub-disciplines in taking the opportunity to get a look at 3I/ATLAS on its journey through the solar system. They received approval to interrupt Webb’s planned schedule of observations to make use of its NIRSpec (Near-Infrared Spectrograph) instrument to study the comet.
NIRSpec revealed exceptionally high levels of deuterium, about 30 times more than seen in solar system comets. This implies that 3I/ATLAS may have originated in a very cold system much earlier in the history of our galaxy. During its formation, the material that became incorporated into 3I/ATLAS was likely exposed to plenty of radiation, but not any long-term warmth that would have reprocessed its “heavy water” ice, with deuterium, into the type of H2O ice we are familiar with on Earth.
Image: 3I/ATLAS Compared to Solar System Comets These graphs lay out the significant difference in composition between the interstellar comet 3I/ATLAS and comets originating in our solar system. This very specific data helps researchers build a picture of the comet’s original planetary system. Illustration: NASA, ESA, CSA, Martin Cordiner (CUA, NASA-GSFC), Leah Hustak (STScI)Additionally, NIRSpec showed only traces of carbon-13 compared to lighter-weight carbon-12. This also points to a very old origin for 3I/ATLAS, as stellar systems become enriched with carbon-13 over time as generations of stars are born and die in the galaxy. That is why there are higher levels of carbon-13 in our system, around our Sun, which formed relatively recently, 4.5 billion years ago.
The research team estimates that 3I/ATLAS could have formed as long as 10 to 12 billion years ago, during the universe’s “cosmic noon,” when star formation was at its height. Its young origin system was likely ensconced in a relatively cold, dense cloud. The abundance of heavy water shows that 3I/ATLAS spent its formative years in a deeply frozen state.
A separate study using the European Southern Observatory’s Very Large Telescope, led by astronomer Cyrielle Opitom of the University of Edinburgh, complements Webb’s findings with an analysis of 3I/ATLAS’s carbon and nitrogen varieties in the form of the chemical cyanide.
“For us as scientists, finding these rare isotopes is fascinating, but the bigger picture here is looking at the possibilities of prebiotic chemistry elsewhere in the galaxy,” said Stefanie Milam of NASA Goddard and co-author of the study with Cordiner. “So far, we know of only one place in the vast cosmos where chemical ingredients led to life – our solar system, our Earth. Analysis of these interstellar objects is a major step towards learning how common, or uncommon, the conditions for the evolution of life are in the universe.”
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it.

Curiosity Blog, Sols 4920-4926: Surveying the Bands NASA’s Mars rover Curiosity acquired this image of small butte, “Miraflores,” using its Mast Camera (Mastcam) on June 11, 2026 — Sol 4922, or Martian day 4,922 of the Mars Science Laboratory mission — at 09:12:13 UTC. NASA/JPL-Caltech/MSSSWritten by William Farrand, Senior Research Scientist, Space Science Institute
Earth planning date: Friday, June 12, 2026
Rather than going from stage to stage at a music festival to hear different bands playing different varieties of music, Curiosity has been ascending up Mount Sharp through physical bands of exposed rocks with textural and tonal differences.
Planning for sols 4920 and 4921 were done with the rover in the middle of a unit with a rougher texture and dark-toned bedrock. With the rougher-textured bedrock, brushing wasn’t possible, but APXS chemistry and MAHLI micro-imaging were planned on “as is” bedrock targets “Salto La Cascada” and “Puerto de Rosas.” ChemCam was targeted to perform LIBS spectroscopy on a bedrock target “Kishuara” and a small, layered float rock “La Rosita.” ChemCam’s Remote Micro-Imager (RMI) collected views of the “Mishe Mokwa” butte and another looking at dunes with tonal differences. Mastcam mosaics were collected on the “Valle Grande” channel, “Kimsa Chata” butte, nearby troughs, and the aircraft carrier shaped rock “El Matir.”
Another drive brought Curiosity closer to the upper border of the dark-toned band. Again, brushing of the rocks was not possible, but APXS and MAHLI were collected on dark-toned bedrock targets “Santa Gracia” and “Laguna San Rafael” with ChemCam LIBS also targeting the bedrock. Mastcam mosaics were collected of a layered rock and nearby troughs and a mosaic of the nearby smaller butte, “Miraflores” which displays an interesting layered structure with ragged dark-toned rocks on one side and a stack of dust piled on top (see accompanying image). Other activities included a long-distance RMI mosaic of a bright unit on “Mishe Mokwa”, and Navcam dust-devil surveys in both sols.
Communicating between Earth and Mars has come to seem routine, but at times can still be a challenging endeavor and this was demonstrated to the team on Friday when we did not get a timely downlink of data for the drive planned for Sol 4923. Without these images another drive, in situ examinations, or targeted remote sensing could not be planned. However, there are always interesting things to be done on Mars and the three-sol plan (4924 to 4926) included a 360-degree Mastcam mosaic, the automatic AEGIS targeting of LIBS measurements on each sol, a Navcam dust-devil survey, APXS atmospheric measurements, as well as several other environmental activities.
On Monday, the delayed downlink will be used to plan the first investigation of the next band of surface materials, this one being smooth-textured and light-toned, as well as another drive to continue the surveying of the bands.

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