The colors indicate different types of land cover.NASA/JPL-Caltech This same Nov. 29, 2025, image from NISAR’s L-band SAR instrument features labels noting cities and geographic features of the Mississippi River Delta region. Colors indicate types of land cover, such as healthy forests (bright green), thinned tree populations (yellow-and-magenta hues), and tall crops (bright magenta).NASA/JPL-Caltech A new image from the NISAR mission shows off the satellite’s ability to reveal details of Earth’s surfaces. The science team also released new sample data. A U.S.-Indian Earth satellite’s ability to see through clouds, revealing insights and characteristics of our planet’s surface, is on display in a colorful, newly released image showing the Mississippi River Delta region in southeastern Louisiana. Created with data collected by the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite in late fall, the image shows the cities of New Orleans and Baton Rouge, the Mississippi River, Lake Pontchartrain, and a diversity of wetlands, farmland, forests, and communities. It also highlights the key difference between radar, which scans surfaces with microwaves, and technologies that sense visible light: Optical imagery from other instruments taken the same day showed the region largely obscured by clouds. This image comes as the NISAR project prepares to make thousands of mission data files available for download in late February. The mission also recently released a smaller set of sample files to help data users prepare to utilize the broader dataset. While the Earth-observing satellite went through checks to verify the health of all its systems after launching in July, the mission’s NASA science team — researchers and data scientists from a range of disciplines spread around the U.S. — pulled preliminary measurements from its L-band synthetic aperture radar (SAR) instrument to generate maps such as this one that demonstrate the instrument’s capabilities. Built by NASA’s Jet Propulsion Laboratory in Southern California, the L-band radar employs microwaves that, due to their 9-inch (24-centimeter) wavelength, can pass uninterrupted through clouds and image the surface below clearly. What’s revealed Captured Nov. 29, the image demonstrates how the L-band SAR can discern what type of land cover — low-lying vegetation, trees, and human structures — is present in each area. This capability is vital both for monitoring the gain and loss of forest and wetland ecosystems, as well as for tracking the progress of crops through growing seasons around the world. The colors seen here represent varying types of cover, which tend to reflect microwaves back to the satellite differently. Portions of New Orleans appear green, a sign that the radar’s signals may be scattering from buildings that are oriented at different angles relative to the satellite’s orbit. Parts of the city appear magenta where streets that run parallel to the satellite’s flight track cause the signals to bounce strongly and brightly off buildings and back to the instrument. The resolution of the image is fine enough to make clear, right of center, the Lake Pontchartrain Causeway — twin bridges that, at nearly 24 miles (39 kilometers) in length, make up the world’s longest continuous bridge over water. The bright green areas to the west of the Mississippi River, which snakes from Baton Rouge in the upper left to New Orleans in the lower right, are healthy forests. There, tree canopies and other vegetation caused NISAR’s microwaves to bounce in many directions before returning to the satellite. Meanwhile, the yellow-and-magenta-speckled hues of Maurepas Swamp, directly west of Lake Pontchartrain and the smaller Lake Maurepas, indicate that the tree populations in that wetland forest ecosystem have thinned. On either bank of the Mississippi, the image shows parcels of varying shapes, sizes, and cover. Darker areas suggest fallow farm plots, while bright magenta indicates that tall plants, such as crops, may be present. The data products created with NISAR’s L-band measurements will be downloadable at the website of the Alaska Satellite Facility Distributed Active Archive Center. The Fairbanks-based facility stores and distributes NASA’s SAR data. Insights from NISAR can protect communities by providing unique, actionable information to decision-makers in a diverse range of areas, including disaster response, infrastructure monitoring, and agricultural management. More about NISAR A joint mission developed by NASA and the Indian Space Research Organisation (ISRO), NISAR launched on July 30 from Satish Dhawan Space Centre on India’s southeastern coast. Managed by Caltech, JPL leads the U.S. component of the project and provided the satellite’s L-band SAR and antenna reflector. ISRO provided NISAR’s spacecraft bus and its S-band SAR, which operates at a wavelength of 4 inches (10 centimeters.) The NISAR satellite is the first to carry two SAR instruments at different wavelengths and will monitor Earth’s land and ice surfaces twice every 12 days, collecting data using the spacecraft’s giant drum-shaped reflector, which measures 39 feet (12 meters) wide — the largest radar antenna reflector NASA has ever sent into space.

Credits: NASA Doug Parkinson’s face lights up as he starts telling his story, how someone from Wisconsin now plays a part in the team that will help land the first Artemis astronauts on to the Moon. Parkinson serves as NASA’s SLS (Space Launch System) rocket lead for Launch Integration and Mission Operations, guiding engineers responsible for monitoring the rocket during testing, pre-launch, and launch activities. Following his father’s footsteps, Parkinson became a mechanical engineer, studying at the University of Alabama in Huntsville. He had planned on working in computer technologies or on cars in his future. Then the opportunity appeared to work with higher-powered engines. NASA’s Doug Parkinson is the Launch Integration and Mission Operations lead for the SLS (Space Launch System) Program.NASA “I came across an opportunity to work at the Propulsion Research Center at the university. I studied new propulsion technologies. That intrigued me because, as an undergrad, it was a chance to put into practical use what I was learning in the books and in theory,” said Parkinson. “It ended up being a lot of fun and very educational. It was in cutting edge technologies that really inspired me.” Joining NASA at Marshall Space Flight Center in Huntsville, Alabama, in 1999, he began helping develop advanced liquid rocket engines, including the Fastrac and J-2X engines. The J-2X was an advanced development of the upper stage engine used on the Saturn V. “In 2012, I moved to SLS. One of the things I learned in the propulsion area with all the engine testing was test operations. That translated well into my new role as operations lead for the stages element,” said Parkinson. Now, he also serves as one of the SLS Engineering Support Center managers, helping oversee and train the SLS Engineering Support Team responsible for monitoring the rocket’s systems. The team operates at NASA Marshall and is critical to verifying the rocket is performing well. Parkinson is the first person to hold the Launch Integration and Mission Operations leadership position in the SLS Program. “I love all aspects of the operations. I like getting my hands dirty. I like seeing the erector set go together,” said Parkinson. When the Artemis II astronauts fly by the Moon, soaring within just a few thousand miles of the lunar surface, they will do so having been launched on a rocket Parkinson helped develop. I have goosebumps just thinking about it,” he said. “I’ll be on console for part of that time, listening to what they have to say. It’s amazing to think we’re going to go do that. /wp-content/plugins/nasa-blocks/assets/images/article-c-daren-welsh.jpg Doug Parkinson Launch Integration and Mission Operations Lead for the SLS (Space Launch System) Program “I have goosebumps just thinking about it,” he said. “I’ll be on console for part of that time, listening to what they have to say.

On Tuesday, March 3, 2026, a total lunar eclipse will take place across several time zones. In this data visualization, the Moon moves from right to left, passing through Earth’s shadow and leaving in its wake an eclipse diagram with the times (in UTC) at various stages of the eclipse. Credit: NASA’s Scientific Visualization Studio A total lunar eclipse will redden the Moon on March 3, 2026. Here’s what you need to know. How does a lunar eclipse work? A lunar eclipse occurs when Earth passes directly between the Sun and Moon, casting a gigantic shadow across the lunar surface and turning the Moon a deep reddish-orange. This alignment can only occur during a full Moon phase. Alignment of the Moon, Earth, and Sun during a lunar eclipse (not to scale). NASA’s Scientific Visualization Studio How can I observe the eclipse? You can observe a lunar eclipse without any special equipment. All you need is a line of sight to the Moon! For a more dramatic observing experience, seek a dark environment away from bright lights. Binoculars or a telescope can also enhance your view. On March 3, totality will be visible in the evening from eastern Asia and Australia, throughout the night in the Pacific, and in the early morning in North and Central America and far western South America. The eclipse is partial in central Asia and much of South America. No eclipse is visible in Africa or Europe. Map showing where the March 3, 2026 lunar eclipse is visible. Contours mark the edge of the visibility region at eclipse contact times, labeled in UTC. NASA’s Scientific Visualization Studio What can I expect to see? Milestone: What’s happening: Penumbral eclipse begins (12:44 a.m. PST, 3:44 a.m. EST, 8:44 UTC) The Moon enters the Earth’s penumbra, the outer part of the shadow. The Moon begins to dim, but the effect is quite subtle. Partial eclipse begins (1:50 a.m. PST, 4:50 a.m. EST, 9:50 UTC) The Moon begins to enter Earth’s umbra and the partial eclipse begins. To the naked eye, as the Moon moves into the umbra, it looks like a bite is being taken out of the lunar disk. The part of the Moon inside the umbra appears very dark. Totality begins (3:04 a.m. PST, 6:04 a.m. EST, 11:04 UTC) The entire Moon is now in the Earth’s umbra. The Moon is tinted a coppery red. Try binoculars or a telescope for a better view. If you want to take a photo, use a camera on a tripod with exposures of at least several seconds. Totality ends (4:03 a.m. PST, 7:03 a.m. EST, 12:03 UTC) As the Moon exits Earth’s umbra, the red color fades. It looks as if a bite is being taken out of the opposite side of the lunar disk from before. Partial eclipse ends (5:17 a.m. PST, 8:17 a.m. EST, 13:17 UTC) The whole Moon is in Earth’s penumbra, but again, the dimming is subtle. Penumbral eclipse ends (6:23 a.m. PST, 9:23 a.m. EST, 14:23 UTC) The eclipse is over. Why is a lunar eclipse sometimes called a “blood Moon”? During a total lunar eclipse, the Moon appears dark red or orange. This is because our planet blocks most of the Sun’s light from reaching the Moon, and the light that does reach the lunar surface is filtered through a thick slice of Earth’s atmosphere. It’s as if all of the world’s sunrises and sunsets are projected onto the Moon. Learn more: Why does the Moon turn red during a solar eclipse? Data visualization showing a telescopic view of the Moon as the March 2026 total lunar eclipse unfolds. Credit: NASA’s Scientific Visualization Studio What else can I observe on the night of the eclipse? As Earth’s shadow dims the lunar surface, constellations may be easier to spot than they usually are during a full Moon. At the time of the eclipse, the Moon will be in the constellation Leo, under the lion’s hind paws. Several days later, on March 8, look for a “conjunction” of Venus and Saturn: from our perspective on Earth, these two planets will appear close to each other in the sky (though they’ll still be very distant from each other in space).

This image of the Atlantic Ocean around Florida, the Bahamas, and Cuba was taken from the International Space Station in 2024. Coastal areas are particularly vulnerable to sea level rise. A NASA analysis shows that the global mean sea level rose 0.03 inches (0.08 centimeters) in 2025.NASA A mild La Niña caused greater rainfall over the Amazon basin, which offset rising sea levels due to record warming of Earth’s oceans. The rise in the global mean sea level slowed in 2025 relative to the year before, an effect largely due to the La Niña conditions that persisted over most of the year. According to a NASA analysis, the average height of the ocean increased last year by 0.03 inches (0.08 centimeters), down from 0.23 inches (0.59 centimeters) in 2024. The 2025 figure also fell below the long-term expected rate of 0.17 inches (0.44 centimeters) per year based on the rate of rise since the early 1990s. Though sea levels have increasingly trended upward in that *******, years during which the rise in the average height was less usually have occurred during La Niñas — the part of the El Niño-Southern Oscillation cycle that cools the eastern Pacific Ocean, often leading to heavy rainfall over the equatorial portions of South America. This graph shows the rise in global mean sea level from 1993 to 2025 based on data from a series of five international satellites. The solid red line indicates an accelerating rate of increase, which has more than doubled over three-plus decades. The dotted red line projects future sea level rise.NASA/JPL-Caltech The current La Niña has been relatively mild. Even so, the extra precipitation it has poured on the Amazon River basin contributed to an overall shift of water from oceans to land. This effect tends to temporarily lower sea levels, offsetting the rise caused by melting glaciers and ice sheets and warming of the oceans, which raises sea levels through the expansion of water when the temperature increases. The net result in 2025 was a lower-than-average sea level rise. “The weather gives us a wild ride, and what we saw with sea level rise last year is part of that ride,” said Josh Willis, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California. “But that cycle is short-lived. The extra water in the Amazon is going to reach the oceans in less than a year, and rapid rise will soon return.” Combined effects To calculate the global mean sea level in 2025, scientists averaged data across space and time from Sentinel-6 Michael Freilich, the current official reference satellite for sea level measurements and one of a line of missions developed by NASA and its U.S. and European partners to track the height of about 90% of Earth’s oceans every 10 days. Then, to better understand the factors that contributed to the rise last year, the researchers looked at measurements from other sources. Among them was the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO), a twin-satellite mission launched by NASA and the ******* Research Centre for Geosciences that tracks the movement of water (liquid and frozen) by measuring changes in Earth’s gravity over land and ice masses. The GRACE data indicated that even as ice loss from glaciers and ice sheets continued a long-term trend of water moving from land to oceans, an outsize amount of water moved in the opposite direction in 2025: The heavier-than-normal rainfall due to La Niña shifted water from the oceans to the Amazon basin. Meanwhile, data from Argo, an international program that uses thousands of seaborne probes to measure ocean temperatures and salinity, showed record warming of the oceans in 2025. The combined effect of the two factors — one tending to lower sea levels and the other tending to increase them — resulted in an average rise in sea level in 2025 that was less than the average rate based on the long-term data record. Actionable, accurate, consistent The continuous series of ocean-observing satellites started with TOPEX/Poseidon, which launched in 1992. Sentinel-6 Michael Freilich, launched in 2020 and took over in 2022 from its predecessor, Jason-3, which is still in orbit and celebrated its 10th launch anniversary on Jan. 17. In coming months, Sentinel-6 Michael Freilich will pass the baton to its twin, Sentinel-6B, which launched in November. Sentinel-6B is expected to continue ocean measurements for at least five years. Over more than three decades, the satellites have offered actionable, accurate, and consistent measurements at both local and global scales. These measurements have formed the basis for U.S. flood predictions, which are crucial for safeguarding coastal infrastructure and communities. The dataset indicates that the average global sea level has gone up by 4 inches (10 centimeters) since 1993. While it’s not uncommon to see short-term ups and downs, the overall trend shows that the rate of annual sea level rise has more than doubled. “As seas continue to rise globally, satellite monitoring empowers communities worldwide to anticipate risks and build resilience,” said Nadya Shiffer, head of physical oceanography programs at NASA Headquarters in Washington.

7 min read NASA Researchers Probe Tangled Magnetospheres of Merging Neutron Stars New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in the moments before they ******. The team identified potential signals emitted during the stars’ final moments that may be detectable by future observatories. “Just before neutron stars ******, the highly magnetized, plasma-filled regions around them, called magnetospheres, start to interact strongly. We studied the last several orbits before the merger, when the entwined magnetic fields undergo rapid and dramatic changes, and modeled potentially observable high-energy signals,” said lead scientist Dimitrios Skiathas, a graduate student at the University of Patras, Greece, who is conducting research for the Southeastern Universities Research Association in Washington at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. New supercomputer simulations explore the tangled magnetic structures around merging neutron stars. Called magnetospheres, the highly magnetized, plasma-filled regions start to interact as the city-sized stars close on each other toward their final orbits. Magnetic field lines can connect both stars, break, and reconnect, while currents surge through surrounding plasma moving at nearly the speed of light. The simulations show that as these systems merge to produce one kind of gamma-ray burst — the universe’s most powerful class of explosions — they emit tell-tale X-rays and gamma rays that future observatories should be able to detect. NASA’s Goddard Space Flight Center Download images and videos through NASA’s Scientific Visualization Studio A paper describing the findings published Nov. 20, 2025, in the The Astrophysical Journal. Neutron star mergers produce a particular type of GRB (gamma-ray burst), the most powerful class of explosions in the cosmos. Most investigations have naturally concentrated on the spectacular mergers and their aftermaths, which produce near-light-speed jets that emit gamma rays, ripples in space-time called gravitational waves, and a so-called kilonova explosion that forges heavy elements like gold and platinum. A merger observed in 2017 dramatically confirmed the long-predicted connections between these phenomena — and remains the only event seen so far to exhibit all three. Neutron stars pack more mass than our Sun into a ball about 15 miles (24 kilometers) across, roughly the length of Manhattan Island in New York City. They form when the core of a massive star runs out of fuel and collapses, crushing the core and triggering a supernova explosion that blasts away the rest of the star. The collapse also revs up the core’s rotation and amplifies its magnetic field. In our simulations, the magnetosphere behaves like a magnetic circuit that continually rewires itself as the stars orbit. Constantinos Kalapotharakos Newborn neutron stars can spin dozens of times a second and wield some of the strongest magnetic fields known, up to 10 trillion times stronger than a refrigerator magnet. That’s strong enough to directly transform gamma-rays into electrons and positrons and rapidly accelerate them to energies far beyond anything achievable in particle accelerators on Earth. “In our simulations, the magnetosphere behaves like a magnetic circuit that continually rewires itself as the stars orbit. Field lines connect, break, and reconnect while currents surge through plasma moving at nearly the speed of light, and the rapidly varying fields can accelerate particles,” said co-author Constantinos Kalapotharakos at NASA Goddard. “Following that nonlinear evolution at high resolution is exactly why we need a supercomputer!” Using the Pleiades supercomputer at NASA’s Ames Research Center in California’s Silicon Valley, the team ran more than 100 simulations of a system of two orbiting neutron stars, each with 1.4 solar masses. The goal was to explore how different magnetic field configurations affected the way electromagnetic energy — light in all of its forms — left the binary system. Most of the simulations describe the last 7.7 milliseconds before the merger, enabling a detailed study of the final orbits. “Our work shows that the light emitted by these systems varies greatly in brightness and is not distributed evenly, so a far-away observer’s perspective on the merger matters a great deal,” said co-author Zorawar Wadiasingh at the University of Maryland, College Park and NASA Goddard. “The signals also get much stronger as the stars get closer and closer in a way that depends on the relative magnetic orientations of the neutron stars.” Magnetic field lines anchored to the surfaces of each star sweep behind them as the stars orbit. Field lines may directly connect one star to the other as the orbits shrink, while lines already linking the stars may break and reconfigure. One value of studies like this is to help us figure out what future observatories might be able to see and should be looking for in both gravitational waves and light. Demosthenes Kazanas Using the simulations, the team also computed electromagnetic forces acting on the stars’ surfaces. While the effects of gravity dominate, these magnetic stresses could accumulate in strongly magnetized systems. Future models may help reveal how magnetic interactions influence the last moments of the merger. “Such behavior could be imprinted on gravitational wave signals that would be detectable in next-generation facilities. One value of studies like this is to help us figure out what future observatories might be able to see and should be looking for in both gravitational waves and light,” said Goddard’s Demosthenes Kazanas. The team, which includes Alice Harding at the Los Alamos National Laboratory in New Mexico and Paul Kolbeck at the University of Washington in Seattle, then used the simulated fields to identify where the highest-energy emission would be produced and how it would propagate. This view of a supercomputer simulation of merging, magnetized neutron stars highlights regions producing the highest-energy light. Brighter colors indicate stronger emission. These regions produce gamma rays with energies trillions of times greater than that of visible light, but likely none of it could escape. That’s because the highest-energy gamma rays quickly convert to particles in the presence of the stars’ powerful magnetic fields. However, gamma rays at lower energies, with millions of times the energy of visible light, can exit the merging system, and the resulting particles may also radiate at still lower energies, including X-rays. The emission varies rapidly and is highly directional, but it could potentially be detected by future facilities. NASA’s Goddard Space Flight Center/D. Skiathas et al. 2025 In the chaotic plasma surrounding the neutron stars, particles transform into radiation and vice versa. Speedy electrons emit gamma rays, the highest-energy form of light, through a process called curvature radiation. A gamma-ray photon can interact with a strong magnetic field in a way that transforms it into a pair of particles, an electron and a positron. The study found regions producing gamma rays with energies trillions of times greater than that of visible light, but likely none of it could escape. The highest-energy gamma rays quickly converted to particles in the presence of powerful magnetic fields. However, gamma rays at lower energies, with millions of times the energy of visible light, can exit the merging system, and the resulting particles may also radiate at still lower energies, including X-rays. The finding suggests that future medium-energy gamma-ray space telescopes, especially those with wide fields of view, may detect signals originating in the runup to the merger if gravitational-wave observatories can provide timely alerts and sky localization. Today, ground-based gravitational-wave observatories, such as LIGO (Laser Interferometer Gravitational-Wave Observatory) in Louisiana and Washington, and Virgo in Italy, detect neutron star mergers with frequencies between 10 and 1,000 hertz and can enable rapid electromagnetic follow-up. ESA (European Space Agency) and NASA are collaborating on a space-based gravitational-wave observatory named LISA (Laser Interferometer Space Antenna), planned for launch in the 2030s. LISA will observe neutron-star binaries much earlier in their evolution at far lower gravitational-wave frequencies than ground-based observatories, typically long before they merge. Future gravitational-wave observatories will be able to alert astronomers to systems on the verge of merging. Once such systems are found, wide-field gamma-ray and X-ray observatories could begin searching for the pre-merger emission highlighted by these simulations. Routine observation of events like these using two different “messengers” — light and gravitational waves — will provide a major leap forward in understanding this class of GRBs, and NASA researchers are helping to lead the way.

A new image from NASA’s James Webb Space Telescope of a portion of the Helix Nebula highlights comet-like knots, fierce stellar winds, and layers of gas shed off by a dying star interacting with its surrounding environment. Webb’s image also shows the stark transition between the hottest gas to the coolest gas as the shell expands out from the central white dwarf.NASA, ESA, CSA, STScI; Image Processing: Alyssa Pagan (STScI) NASA’s James Webb Space Telescope has zoomed into the Helix Nebula to give an up-close view of the possible eventual fate of our own Sun and planetary system. In Webb’s high-resolution look, the structure of the gas being shed off by a dying star comes into full focus. The image reveals how stars recycle their material back into the cosmos, seeding future generations of stars and planets, as NASA explores the secrets of the universe and our place in it. In the image from Webb’s NIRCam (Near-Infrared Camera), pillars that look like comets with extended tails trace the circumference of the inner region of an expanding shell of gas. Here, blistering winds of fast-moving hot gas from the dying star are crashing into slower moving colder shells of dust and gas that were shed earlier in its life, sculpting the nebula’s remarkable structure.

7 Min Read Building Roman NASA’s Nancy Grace Roman Space Telescope is now assembled following the integration of its two major segments, shown in this time-lapse. Credits: NASA/Sophia Roberts Technicians have completed the construction of NASA’s Nancy Grace Roman Space Telescope. The Roman observatory is slated to launch no later than May 2027, with the team aiming for as early as fall 2026. The mission will revolutionize our understanding of the universe with its deep, crisp, sweeping views of space. More than a thousand technicians and engineers assembled Roman from millions of individual components. Many parts were built and tested simultaneously to save time. Now that the observatory is assembled, it will undergo a spate of testing prior to shipping to NASA’s Kennedy Space Center in Florida in summer 2026. NASA’s freshly assembled Nancy Grace Roman Space Telescope will revolutionize our understanding of the universe with its deep, crisp, sweeping infrared views of space. The mission will transform virtually every branch of astronomy and bring us closer to understanding the mysteries of dark energy, dark matter, and how common planets like Earth are throughout our galaxy. Roman is on track for launch by May 2027, with teams working toward a launch as early as fall 2026. Credit: NASA’s Goddard Space Flight Center Telescope The Optical Telescope Assembly is the heart of the Roman observatory. It consists of a primary mirror, which was designed and built at L3Harris Technologies in Rochester, New York, plus nine additional mirrors and supporting structures and electronics. The Roman team got a jumpstart by receiving the telescope’s primary mirror, which will collect and focus light from cosmic objects near and far, from another government agency and then modifying it to meet NASA’s needs. Using this mirror, Roman will capture stunning space vistas with a field of view at least 100 times larger than Hubble’s. Roman will peer through dust and across vast stretches of space and time to study the universe using infrared light, which human eyes can’t see. The amount of detail these observations will reveal is directly related to the size of the telescope’s mirror, since a larger surface gathers more light and measures finer features. Roman’s primary mirror is 7.9 feet (2.4 meters) across, the same size as the Hubble Space Telescope’s main mirror but less than one-fourth the weight (410 pounds, or 186 kilograms) thanks to major improvements in technology. “The telescope will be the foundation of all of the science Roman will do, so its design and performance are among the largest factors in the mission’s survey capability.” /wp-content/plugins/nasa-blocks/assets/images/article-c-daren-welsh.jpg Josh Abel lead Optical Telescope Assembly systems engineer at NASA Goddard The Roman team modified the inherited mirror’s shape and surface to meet the mission’s science objectives. The mirror sports a layer of silver less than 400 nanometers thick — about 200 times thinner than a human hair. The silver coating was specifically chosen for Roman because of how well it reflects near-infrared light. Roman’s mirror is so finely polished that the average bump on its surface is only 1.2 nanometers tall — more than twice as smooth as the mission requires. If the mirror were scaled to be Earth’s size, these bumps would be just a quarter of an inch high. NASA/Chris Gunn Roman’s secondary mirror, photographed here, is 22 inches across. It’s a critical part of the forward structure assembly, which also includes the support structure. NASA/Chris Gunn An optical technician lays on a diving board suspended between NASA’s Nancy Grace Roman Space Telescope’s primary and secondary mirrors. The photo is a projected reflection through the telescope’s optical path. The technician shines a beam of light through the optical system toward the future location of the Wide Field Instrument, showing how light from cosmic sources will travel through the telescope once the mission launches. NASA/Chris Gunn Optical engineer Bente Eegholm inspects the surface of Roman’s primary mirror. NASA/Chris Gunn The primary mirror, in concert with other optics, will send light to Roman’s two science instruments: the Wide Field Instrument and Coronagraph Instrument. When light enters Roman’s 2.4-meter aperture, it will be reflected and focused by the curved primary mirror and then reflected and focused once more by the secondary mirror. Then, light from different parts of the sky splits off toward each instrument, so Roman will be able to use both at once. The telescope was delivered Nov. 7, 2024, to the largest clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Upon arrival at NASA’s Goddard Space Flight Center, Roman’s Optical Telescope Assembly was lifted out of the shipping fixture and placed with other mission hardware in Goddard’s largest clean room. Then, it was installed onto Roman’s Instrument Carrier, a structure that will keep the telescope and Roman’s two instruments optically aligned.

This device will convert starlight into electrical signals, which will then be decoded into 288-megapixel images of large patches of the sky. The combination of Roman’s fine resolution and enormous images has never been possible on a space-based telescope before. Roman uses state-of-the-art sensors that build on the legacy of the infrared detectors in NASA’s Hubble and Webb instruments. Roman’s focal plane, however, is much larger to capture a much larger field of view. Greg Mosby research astrophysicist at NASA Goddard The detectors, each the size of a saltine cracker, have 16 million tiny pixels apiece, providing the mission with exquisite image resolution. Eighteen were incorporated into the focal plane array for Roman’s camera, and another six are reserved as flight-qualified spares.

By tweaking the curvatures and tilts of three mirrors, Roman focuses light instead onto a ring around the center. The detectors in Roman’s Wide Field Instrument are laid out in an arch shape to sit along part of that ring. This design helps Roman capture a much wider area with equally sharp imaging. And since the observatory’s Coronagraph is placed on another part of the ring, both instruments can operate simultaneously while benefiting from the telescope’s best resolution. Credit: NASA/Chris Gunn Principal technician Billy Keim installs a cover plate over the detectors for NASA’s Nancy Grace Roman Space Telescope. Credit: NASA/Chris Gunn Once complete and tested, the detector array was inserted into the mission’s primary instrument: a sophisticated camera called the Wide Field Instrument, which was assembled and tested at Goddard and BAE Systems, Inc. Wide Field Instrument The Wide Field Instrument, or WFI, is an infrared camera that will give Roman the same angular resolution as Hubble but with a field of view at least 100 times larger. Its sweeping cosmic surveys will help scientists discover new and uniquely detailed information about planets beyond our solar system, untangle mysteries like dark energy, and map how matter is structured and distributed throughout the cosmos. The mission’s broad, crisp view will produce an extraordinary resource for a wide range of additional investigations. Using this instrument, each Roman image will capture a patch of the sky ******* than the apparent size of a full moon. The mission will gather data hundreds of times faster than Hubble, adding up to 20,000 terabytes (20 petabytes) over the course of its five-year primary mission. This photo shows Roman’s Wide Field Instrument arriving at the big clean room at NASA’s Goddard Space Flight Center. About the size of a commercial refrigerator, this instrument will help astronomers explore the universe’s evolution and the characteristics of worlds outside our solar system. Unlocking these cosmic mysteries and more will offer a better understanding of the nature of the universe and our place within it. NASA/Chris Gunn Technicians install Roman’s Wide Field Instrument in the biggest clean room at NASA’s Goddard Space Flight Center in Greenbelt, Md. This marked the final step to complete the Roman payload, which also includes a Coronagraph instrument and the Optical Telescope Assembly. NASA/Chris Gunn After completing final integration, Ball Aerospace technicians transport the Nancy Grace Roman Space Telescope’s Wide Field Instrument (WFI) into Ball’s largest thermal vacuum chamber to begin environmental testing at a Ball facility in Boulder, Colorado. Ball Aerospace Technicians from both BAE and Goddard put the WFI together in a clean room in Boulder, Colorado. Then the team completed full environmental testing in space-like conditions and delivered the WFI to Goddard in summer 2024. It was joined to other observatory systems the following winter. Coronagraph Instrument Technicians at NASA’s Jet Propulsion Laboratory built the Coronagraph Instrument. The Coronagraph will demonstrate new technologies for directly imaging planets around other stars. It will block the glare from distant stars and make it easier for scientists to see the faint light from planets in orbit around them. The Coronagraph aims to photograph worlds and dusty disks around nearby stars in visible light to help us see giant worlds that are older, colder, and in closer orbits than the hot, young super-Jupiters direct imaging has mainly revealed so far. The coronagraph team will conduct a series of pre-planned observations for three months spread across the mission’s first year-and-a-half of operations, after which the mission may conduct additional observations based on scientific community input. Following testing JPL, the Coronagraph was delivered to Goddard in May 2024. It was integrated onto Roman’s Instrument Carrier, a piece of infrastructure that will hold the mission’s instruments, in October 2024. Then the instrument carrier was joined to the spacecraft in December 2024. The Roman Coronagraph was integrated with the Instrument Carrier in a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Md., in October 2024. NASA/Sydney Rohde April 9, 2025The Roman Coronagraph was peppered with radio waves to test its response to stray electrical signals. The test was performed inside a chamber lined with foam padding that absorbs the radio waves to prevent them from bouncing off the walls. Credit: NASA/JPL-Caltech. NASA/JPL-Caltech PIA26273 This photo features the optical bench for Roman’s Coronagraph Instrument. Light from the telescope will be directed to the optical bench and pass through series of lenses, filters, and other components that ultimately suppress light from a star while allowing the light from orbiting planets to pass through. Mirrors redirect the light and keep it contained within the optical bench. In this image, the bench was partly assembled at the start of the instrument’s integration and testing *******. The large ****** circles are surrogate components that were standing in for the actual instrument hardware. NASA/JPL-Caltech By 2025, all of Roman’s components were complete and undergoing testing as subsystems. Technicians installed test versions of the Solar Array Sun Shield panels onto the Outer Barrel Assembly — a part of the observatory that will protect and shade the primary mirror — inside Goddard’s largest clean room in preparation for testing. The team covered Roman’s telescope section in a protective tent and pushed it out of the clean room using pressurized air to float it like a hovercraft. Then they lifted it onto a shaker table for vibration testing to simulate launch stress. Then, technicians moved the components into the Space Environment Simulator chamber for a month of testing at low pressure and different temperatures, mimicking space-like conditions. Solar Panels Roman’s Solar Array Sun Shield is made up of six panels, each covered in solar cells. The two central panels will remain fixed to the Outer Barrel Assembly while the other four will deploy once Roman is in space, swinging up to align with the center panels. The panels will spend the entirety of the mission facing the Sun to provide a steady supply of power to the observatory’s electronics. This orientation will also shade much of the observatory and help keep the instruments cool, which is critical for an infrared observatory. Since infrared light is detectable as heat, excess warmth from the spacecraft’s own components would saturate the detectors and effectively blind the telescope. In this photo, technicians install solar panels onto the outer portion of the Roman observatory. Roman’s inner portion is in the background just left of center. NASA/Sydney Rohde The Roman solar panels are covered in a total of 3,902 solar cells that will convert sunlight directly into electricity much like plants convert sunlight to chemical energy. When tiny bits of light, called photons, strike the cells, some of their energy transfers to electrons within the material. This jolt excites the electrons, which start moving more or jump to higher energy levels. In a solar cell, excited electrons create electricity by breaking free and moving through a circuit, sort of like water flowing through a pipe. The panels are designed to channel that energy to power the observatory. Credit: NASA/Sydney Rohde Technicians installed Roman’s solar panels in June of 2025, followed by the Lower Instrument Sun Shield — a smaller set of panels that will play a critical role in keeping Roman’s instruments cool and stable. Technicians practiced deploying the solar panels and Deployable Aperture Cover — a visor-like sunshade. By fall 2025, the observatory was in two major segments. The inner portion included the telescope, instrument carrier, two instruments, and spacecraft bus while the outer portion consisted of the outer barrel assembly, deployable aperture cover, and solar panels. The outer portion passed a shake test and an intense sound blast while the inner portion underwent a 65-day thermal vacuum test. On November 25, 2025, technicians joined the two segments together and the observatory was complete.

Next, Roman will undergo final testing prior to moving to the launch site at NASA’s Kennedy Space Center in Florida for launch preparations in summer 2026. Credit: NASA/Sophia Roberts NASA/Sophia Roberts “With Roman’s construction complete, we are poised at the brink of unfathomable scientific discovery. In the mission’s first five years, it’s expected to unveil more than 100,000 distant worlds, hundreds of millions of stars, and billions of galaxies. We stand to learn a tremendous amount of new information about the universe very rapidly after Roman launches.” Julie Mcenery Roman senior project scientist at NASA Goddard Now, Roman will undergo testing as a full observatory. Roman will move to the launch site at NASA’s Kennedy Space Center in Florida for launch preparations in summer 2026.

Although most regions saw average or above-average precipitation in fall and early winter, warmer temperatures meant that much of it fell as rain. The result has been an unusually low snowpack for this time of year, constituting a snow drought. This image, acquired with the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra satellite, provides a wide view of meager western snow cover on January 15. On that day, measurements derived from satellite observations showed that snow blanketed 142,700 square miles (369,700 square kilometers) of the west. That’s the lowest coverage for that date in the MODIS record dating back to 2001 and less than one-third of the median. Coverage had increased slightly by January 26. In addition to snow cover area, snow water equivalent (SWE)—the amount of water stored in the snowpack—is an important indicator of winter conditions in the West. In early January, the National Integrated Drought Information System reported that snow drought, defined as SWE below the 20th percentile for a given date, was most acute in Washington, Oregon, Colorado, Utah, Arizona, and New Mexico. At least one ground-based monitoring station in every major western watershed recorded the lowest SWE in at least 20 years on January 26, according to data published by the USDA Natural Resources Conservation Service. Overall, the preceding few months were very wet and warm across the West. For the water year beginning on October 1, 2025, many regions saw average or above-average precipitation. However, record warmth across a vast expanse of the region meant that much of that precipitation fell as rain rather than snow. A December 2025 atmospheric river in the Pacific Northwest was one such warm precipitation event. One nuance in the snow deficit picture can be found in the Southern Sierra and Northern Rockies, where more precipitation has fallen as snow than rain on the lofty peaks. SWE levels stood above average at some high-elevation locations but were low farther downslope. “This is a classic climate-change, temperature-driven, elevationally dependent snowpack deficit,” said Daniel Swain, climate scientist at the California Institute for Water Resources, in a presentation. Precipitation falling as rain tends to run off before it can recharge reservoirs and groundwater. On the other hand, winter snowpack that melts in the spring can produce a more metered, sustained water supply. The health of the mountain snowpack has implications for ecosystems, wildfire dynamics, and water availability for agriculture and other uses during drier times of the year. There is still a lot of winter remaining, and February and March can bring significant amounts of snow. But snowfall in the coming months may not be able to make up for existing deficits. In places such as the Pacific Northwest and the Colorado River Basin that are already dry, snow drought may turn into or exacerbate traditional drought.

5 Min Read Networks Keeping NASA’s Artemis II Mission Connected An artist’s conceptual image of network antennas supporting the Orion spacecraft. Credits: NASA / Dave Ryan NASA’s Artemis II mission will transport four astronauts around the Moon, bringing the agency one step closer to sending the first astronauts to Mars. Throughout Artemis II, astronaut voice, images, video, and vital mission data must traverse thousands of miles, carried on signals from NASA’s communications systems. Through Artemis, NASA is establishing an enduring presence in space and exploring more of the Moon than ever before. To achieve this, Artemis missions rely on both the Near Space Network and the Deep Space Network. These networks, with oversight by NASA’s SCaN (Space Communications and Navigation) Program office, use global infrastructure and relay satellites to ensure seamless communications and tracking as Orion launches, orbits Earth, travels to the Moon, and returns home. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video NASA’s Artemis II mission will transport four astronauts around the Moon, bringing humanity closer to its journey to Mars. Throughout the mission, astronaut voice, images, video, and vital mission data must traverse thousands of miles, carried on signals from NASA’s powerful communications systems: the Near Space Network and Deep Space Network.NASA “Robust space communications aren’t optional; they’re the essential link that unites the crew and the exploration team on Earth to ensure safety and mission success, as I learned firsthand living and working aboard the International Space Station,” said Ken Bowersox, associate administrator for NASA’s Space Operations Mission Directorate at the agency’s headquarters in Washington. “From real-time conversations with mission controllers, to the data that drives critical decisions and research, and even calls home — space communications keep astronauts connected to mission managers, technical experts, loved ones, and everyone on Earth who wants to share in the excitement of our exploration missions. As we push farther into deep space, reliable communications links will enable more challenging missions and maximize the benefit for all of us on Earth.” "From real-time conversations with mission controllers, to the data that drives critical decisions, research, and even calls home, space communications keep astronauts connected." Ken Bowersox Associate Administrator for NASA's Space Operations Mission Directorate Specialists will operate its networks in tandem to enable data exchange between spacecraft and mission controllers on Earth. NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston will track the Space Launch System rocket, Interim Cryogenic Propulsion Stage, and Orion spacecraft through coordinated handoffs between the networks’ multiple assets on Earth and in space for the duration of the mission. Using ground stations around the globe and a fleet of relay satellites, the Near Space Network will provide communications and navigation services during multiple stages of the Artemis II mission operations. The network, managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has a long legacy of supporting human spaceflight missions near Earth. After Orion’s translunar injection burn, which will set the spacecraft on its planned orbit around the Moon, primary communications support will transition to the Deep Space Network, managed by NASA’s Jet Propulsion Laboratory in Southern California. The network’s international array of giant radio antennas, located in California, Spain, and Australia, provides a near-continuous connection to Orion and its crew. The Artemis II mission will use SCaN’s networks to send vital data down to mission controllers on Earth. This includes astronaut communications, mission health and safety information, images, video, and more.NASA / Dave Ryan “Reliable communications are the lifeline of human spaceflight,” said Kevin Coggins, deputy associate administrator for the SCaN Program at NASA Headquarters. “Our networks help make missions like Artemis II possible and set the stage for even more ambitious space exploration in the years ahead. These achievements are driven not only by NASA’s infrastructure but also by strong collaboration with our commercial partners, who play a critical role in advancing the capabilities and resilience of space communications.” The DSN Now tool displays real-time data in the Charles Elachi Mission Control Center at NASA’s Jet Propulsion Laboratory during the Artemis I launch on November 16, 2022.NASA/JPL-Caltech/Ryan Lannom In addition to traditional radio network support, the spacecraft will host the Orion Artemis II Optical Communications System, a laser communications terminal that will transmit real science and crew data over laser links. Demonstrations like the recent Deep Space Optical Communications payload have proven laser communications systems can send more than 100 times more data than comparable radio networks, even millions of miles away from Earth. While laser communications will not be on Artemis III, the Orion Artemis II Optical Communications System could pave the way for future laser communications systems at the Moon and Mars.

NASA / Dave Ryan The Orion Artemis II Optical Communications System payload is only one piece of NASA’s larger mission to improve lunar and deep space communications. Orion will experience a planned communications blackout lasting approximately 41 minutes. The blackout will occur as the spacecraft passes behind the Moon, blocking radio frequency signals to and from Earth. Similar blackouts occurred during the Apollo-era missions and are expected when using an Earth-based network infrastructure. When Orion reemerges from behind the Moon, the Deep Space Network will quickly reacquire Orion’s signal and restore communications with mission control. These planned blackouts remain an aspect of all missions operating on or around the Moon’s far side. Each Artemis mission will build upon existing capabilities, including data processing and handling. For the Artemis II flight test, data from Orion will be compressed after it reaches Earth to manage the large amount of information. Data compression will reduce image and video quality and give priority to crew communications and mission data.

NASA / Dave Ryan Looking ahead, NASA’s Lunar Communications Relay and Navigation Systems project is collaborating with industry to eliminate blackouts and support precise navigation by placing relay satellites around the Moon. This network of orbiting satellites will deliver persistent, high-bandwidth communications and navigation services for astronauts, landers, and orbiters on and around the lunar surface. In 2024, NASA selected Intuitive Machines to develop the first set of lunar relays for demonstration during the Artemis III lunar surface mission. From liftoff to splashdown, NASA’s evolving networks will serve as the crew’s link home, ensuring that humanity’s return to the Moon stays connected every step of the way.

Frattare X-ray: NASA/CXC/CfA/Á Bogdán; Infrared: NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/P. Edmonds and L. Frattare A new discovery captures the cosmic moment when a galaxy cluster – among the largest structures in the universe – started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope, will lead astronomers to rethink when and how the largest structures in the universe formed. The findings are described in a paper published [Wednesday] in the journal Nature. The object, known as JADES-ID1 for its location in the “JWST Advanced Deep Extragalactic Survey” (JADES) has a mass about 20 trillion times that of the Sun. Astronomers classify JADES-ID1 as a “protocluster” because it is currently undergoing an early, violent phase of formation and will one day turn into a galaxy cluster. However, JADES-ID1 is found at a much larger distance – corresponding to a much earlier time in the universe – than astronomers expected for such systems, providing a new mystery of how it could form so quickly. “This may be the most distant confirmed protocluster ever seen,” said Akos Bogdan of the Center for Astrophysics | Harvard & Smithsonian (CfA) who led the study. “JADES-ID1 is giving us new evidence that the universe was in a huge hurry to grow up.” Galaxy clusters contain hundreds or even thousands of individual galaxies immersed in enormous pools of superheated gas, along with large amounts of unseen dark matter. Astronomers use galaxy clusters to measure the expansion of the universe and the roles of dark energy and dark matter, among other important cosmic studies. “It’s very important to actually see when and how galaxy clusters grow,” said co-author Gerrit Schellenberger, also of CfA. “It’s like watching an assembly line make a car, rather than just trying to figure out how a car works by looking at the finished product.” The Chandra and Webb data reveal that JADES-ID1 contains the two properties that confirm the presence of a protocluster: a large number of galaxies held together by gravity (Webb sees at least 66 potential members) that are also sitting in a huge cloud of hot gas (detected by Chandra). As a galaxy cluster forms, gas falls inward and is heated by shock waves, reaching temperatures of millions of degrees and glowing in X-rays. What makes JADES-ID1 exceptional is the remarkably early time when it appears in cosmic history. Most models of the universe predict that there likely would not be enough time and a large enough density of galaxies for a protocluster of this size to form only a billion years after the big bang. The previous record holder for a protocluster with X-ray emission is seen much later, about three billion years after the big bang. “We thought we’d find a protocluster like this two or three billion years after the big bang – not just one billion,” said co-author Qiong Li from the University of Manchester in the ***. “Before, astronomers found surprisingly large galaxies and ****** holes not long after the big bang, and now we’re finding that clusters of galaxies can also grow rapidly.” After billions of years JADES-ID1 should evolve from a protocluster into a massive galaxy cluster like those we see much closer to Earth. To find JADES-ID1, astronomers combined deep observations from both Chandra and Webb. By design, the JADES field overlaps with the Chandra Deep Field South, the site of the deepest X-ray observation ever conducted. This field is thus one of the few in the entire sky where a discovery such as this could be made. In an earlier study, a team of researchers led by Li and Conselice found five other proto-cluster candidates in the JADES field, but only in JADES-ID1 are the galaxies embedded in hot gas. Only JADES-ID1 possesses enough mass for an X-ray signal from hot gas to be expected. “Discoveries like this are made when two powerful telescopes like Chandra and Webb stare at the same patch of sky at the limit of their observing capabilities,” said co-author Christopher Conselice, also from the University of Manchester. “A challenge for us now is to understand how this protocluster was able to form so quickly.” NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program.

The image is presented twice, once with, and once without, annotations. The image includes scores of glowing dots and specks of light, in white and golden hues, set against the blackness of space. This layer of the composite visual is from a deep infrared imaging project undertaken by the James Webb Space Telescope. The specks range from relatively large oval galaxies with discernible spiral arms, and glowing ****** with gleaming diffraction spikes, to minuscule pinpoints of distant light. Several of those pinpoints have been circled in the annotated image, as they are part of the distant protocluster. Layered onto the center of this image is a neon blue cloud. This cloud represents hot X-ray gas discovered by Chandra in the deepest X-ray observation ever conducted. In the annotated image, a thin white square surrounds the blue cloud. This represents Chandra’s field of observation. The X-rays from the distant protocluster located within this box are included in the composite image. The protocluster, dubbed JADES-1, has a mass of about 20 trillion suns. It is located some 12.7 billion light-years from Earth, or just a billion years after the big bang. The discovery of a protocluster of this size, at this epoch in the early universe, will lead scientists to re-examine their ideas for how galaxy clusters first appeared in the universe.

NASA Earth Observatory / Lauren Dauphin Natural Color False Color January 26, 2026 CurtainToggle2-Up Image Details A potent winter storm left a wide band of snow stretching from the U.S. Southwest to New England in late January 2026. The heavy snow, along with bitterly cold temperatures, sleet, and ice, created treacherous travel conditions, toppled power lines, and caused widespread school closures, according to news reports. On the afternoon of January 26, the VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite observed new snow covering a large swath of the country. The left image is natural color, while the false-color image on the right uses a combination of visible and infrared light (bands M11-I2-I1) to distinguish snow (blue) from clouds (white). Preliminary National Weather Service data indicate snow accumulations of up to 12 inches (30 centimeters) in parts of Oklahoma between the mornings of January 23 and January 26, with higher accumulation across the Midwest and in New England. Totals of around 20 inches were reported in several Northeast states. Some locations were digging out from record daily accumulations, including 5.1 inches in St. Louis, Missouri, on January 24, and 11.2 inches in Pittsburgh, Pennsylvania, on January 25. Several inches of snow and sleet also fell in parts of North Texas, a rare occurrence for the area. With temperatures remaining below freezing in many places, the snow and ice may stick around. NASA’s Disasters Response Coordination System has been activated to support federal partners responding to the winter storm. The team will be posting maps and data products on its open-access mapping portal as new information becomes available.

3 Min Read NASA Testing Advances Space Nuclear Propulsion Capabilities Written by Daniel Boyette Nuclear propulsion and power technologies could unlock new frontiers in missions to the Moon, Mars, and beyond. NASA has reached an important milestone advancing nuclear propulsion that could benefit future deep space missions by completing a cold-flow test campaign of the first flight reactor engineering development unit since the 1960s. April 8, 2025Crews at NASA’s Marshall Space Flight Center in Huntsville, Alabama, install a flight reactor engineering development unit into Test Stand 400 in preparation for cold-flow testing. The test campaign began in July and ran through September and marked the first testing on a light reactor engineering development unit since the 1960s.NASA/Adam Butt April 9, 2025Crews at NASA’s Marshall Space Flight Center in Huntsville, Alabama, install a flight reactor engineering development unit into Test Stand 400 in preparation for cold-flow testing.

The test campaign began in July and ran through September and marked the first testing on a flight reactor engineering development unit since the 1960s. NASA/Adam Butt April 10, 2025A flight reactor engineering development unit is fully installed at Test Stand 400 in preparation for cold-flow testing. The test campaign began in July and ran through September, marking the first testing on a flight reactor engineering development unit since the 1960s. NASA/Adam Butt “Nuclear propulsion has multiple benefits including speed and endurance that could enable complex deep space missions,” said Greg Stover acting associate administrator of NASA’s Space Technology Mission Directorate at NASA Headquarters in Washington. “By shortening travel times and expanding mission capabilities, this technology will lay the foundation to explore farther into our solar system than ever before. Information from the cold-flow test series is instrumental in understanding the operational characteristics and fluid flow performance of nuclear reactors.” Teams at the agency’s Marshall Space Flight Center in Huntsville, Alabama, conducted more than 100 tests on the engineering development unit over several months in 2025. The 44-inch by 72-inch unit, built by BWX Technologies of Richmond, Virginia, is a full-scale, non-nuclear, flight-like development test article the size of a 100-gallon drum that simulates propellant flow throughout the reactor across a range of operational conditions. The cold-flow tests at NASA Marshall are the culmination of a multi-year activity for the agency and its industry partners. Key test objectives included simulating operational fluid-dynamic responses, gathering critical information for design of the flight instrumentation and control system, providing crucial validation of analytical tools, and serving as a pathfinder for manufacturing, assembly, and integration of near-term flight-capable nuclear propulsion systems. Other benefits to space travel include increasing the science payload capacity and higher power for instrumentation and communication. Test engineers were able to demonstrate that the reactor design is not susceptible to destructive flow-induced oscillations, vibrations or pressure waves that occur when a moving fluid interacts with a structure in a way that makes the system shake. “We’re doing more than proving a new technology,” said Jason Turpin, manager of the Space Nuclear Propulsion Office at NASA Marshall. “This test series generated some of the most detailed flow responses for a flight-like space reactor design in more than 50 years and is a key steppingstone toward developing a flight-capable system. Each milestone brings us closer to expanding what’s possible for the future of human spaceflight, exploration, and science.” The Space Nuclear Propulsion Office is part of NASA’s Technology Demonstration Missions Program within the agency’s Space Technology Mission Directorate.

Key Facts Scientists continue to mine data gathered by NASA’s Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger than Earth, orbiting a Sun-like star about 146 light-years away. The orbital ******* of the planet — listed as a “candidate” pending further confirmation — is likely to be similar to Earth’s, around one year. Planet HD 137010 b also might fall just within the outer edge of its star’s “habitable zone,” the orbital distance that could allow liquid water to form on the planet’s surface under a suitable atmosphere. Planets orbiting other stars are known as “exoplanets.” And this could turn out to be the first exoplanet with Earth-like properties that, from our vantage point, crosses the face of a Sun-like star that is near enough and bright enough for meaningful follow-up observations. Details Now the bad news. The amount of heat and light such a planet would receive from its star is less than a third of what Earth receives from the Sun. Although of a stellar type similar to our Sun, the star, HD 137010, is cooler and dimmer. That could mean a planetary surface temperature no higher than minus 90 degrees Fahrenheit (minus 68 degrees Celsius). By comparison, the average surface temperature on Mars runs about minus 85 degrees Fahrenheit (minus 65 degrees Celsius). Planet HD 137010 b also will need follow-up observations to be promoted from “candidate” to “confirmed.” Exoplanet scientists use a variety of techniques to identify planets, and this discovery comes from a single “transit” — only one instance of the planet crossing its star’s face in a kind of miniature eclipse — detected during Kepler’s second mission, known as K2. Even with just one transit, the study’s authors were able to estimate the candidate planet’s orbital *******. They tracked the time it took for the planet’s shadow to move across the star’s face — in this case 10 hours, while Earth takes about 13 — then compared it to orbital models of the system itself. Still, though the precision of that single detection is much higher than most transits captured by space-based telescopes, astronomers need to see these transits repeat regularly in order to confirm that they are caused by a real planet. And capturing more transits is going to be tricky. The planet’s orbital distance, so similar to Earth’s, means such transits happen far less often than for planets in tighter orbits around their stars (it’s a big reason why exoplanets with Earth-like orbits are so hard to detect in the first place). With luck, confirmation could come from further observation by the successor to Kepler/K2, NASA’s TESS (the Transiting Exoplanet Survey Satellite), the still-functioning workhorse for planetary detection, or from the European Space Agency’s CHEOPS (CHaracterising ExOPlanets Satellite). Otherwise, gathering further data on planet HD 137010 b might have to wait for the next generation of space telescopes.

This view also creates an effect similar to a transit, as the planet’s star disappears and then reappears from behind HD 137010 b.NASA/JPL-Caltech/Keith Miller (Caltech/IPAC) Fun Facts Despite the possibility of a frigid climate, HD 137010 b also could turn out to be a temperate or even a watery world, say the authors of the paper on this exoplanet. It would just need an atmosphere richer in carbon dioxide than our own. The science team, based on modeling of the planet’s possible atmospheres, gives it a 40% chance of falling within the “conservative” habitable zone around the star, and a 51% chance of falling within the broader “optimistic” habitable zone. On the other hand, the authors of the study say the planet has about a 50-50 chance of falling beyond the habitable zone entirely. The Discoverers An international science team published a paper on the discovery, “A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2,” in The Astrophysical Journal Letters on Jan. 27, 2026. The team was led by astrophysics Ph.D. student Alexander Venner of the University of Southern Queensland, Toowoomba, Australia, now a postdoctoral researcher at the Max Planck Institute for Astronomy, Heidelberg, Germany.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A team of NASA scientists deployed on an international mission designed to better understand severe winter storms. The North American Upstream Feature-Resolving and Tropopause Uncertainty Reconnaissance Experiment, or NURTURE, is an airborne campaign that uses a suite of remote sensing instruments to collect atmospheric data on winter weather with a goal of improving the models that feed storm forecasts. This combination of instruments will also serve as a proxy to demonstrate the potential to collect similar observations from space. NASA’s G-III aircraft in the hangar at NASA’s Langley Research Center as science and flight crews install remote sensing instruments inside and onto the body of the plane.NASA/Ryan Hill On Jan. 24, the research team departed from NASA’s Langley Research Center in Hampton, Virginia, aboard the center’s Gulfstream III aircraft (G-III) en route to Goose Bay, Canada. For nearly a month, the plane will be making flights stretching from the Northern Atlantic Ocean over Canada through the Northeast United States, measuring moisture, clouds, and ozone as winter storms develop. The second phase of the campaign, scheduled to fly out of Langley next year, will serve as the inaugural mission of NASA’s new airborne science laboratory, a Boeing 777 These flights will cover a larger range of 3,100 miles (5,000 kilometers) and use a larger suite of instruments. Researchers will collect detailed observations of the atmosphere over Europe, Greenland, the North Atlantic Ocean, Canada, the majority of of the U.S., and much of the Arctic Ocean. “Part of NASA’s role is to leverage our expertise and resources for the benefit of humankind – with innovation always being at our core,” said Will McCarty, weather program manager and program scientist at NASA’s Headquarters in Washington. “The NURTURE campaign is doing exactly that by outfitting our aircraft with one-of-a-kind instruments designed to put our science data into action to understand dangerous weather events before, and as they form.” Research scientist and co-investigator for the NURTURE mission, Amin Nehrir, installing and testing the High Altitude and Lidar Observatory (HALO) instrument aboard the G-III aircraft before deploying.NASA/Ryan Hill As the NASA G-III flies over Canada, a parallel companion mission led by a team of international partners called the North Atlantic Waveguide, Dry Intrusion, and Downstream Impact Campaign (NAWDIC) will be operating out of Shannon, Ireland. Meanwhile, a third airborne mission led by the National Oceanic and Atmospheric Administration (NOAA) will be studying how moisture is transported from the tropics to the Western U.S. By combining the data collected during these campaigns, scientists will be able to track weather systems as they interact and intersect globally to understand the large-scale flows and small-scale features that drive high-impact winter weather events. Software and instrument checks taking place pre-deployment on board the G-III aircraft. HALO and other instruments, like the CloudCube radar, combine to form a specialized suite of atmospheric sensors.NASA/Ryan Hill “These storms are not forecasted very accurately,” said Amin Nehrir, a research scientist at NASA Langley and co-investigator for the NURTURE mission. “Space observations of high latitudes in the Arctic lack the sensitivity needed to gather accurate data in such a dry, atmospheric environment. In lower latitudes, we benefit from observations from radiosondes, surface networks, and satellite observations. We are using cutting-edge technology beyond those that we have in space to get a better snapshot of atmospheric dynamics.” A map showing the two flight paths of the NURTURE mission phases – the G-III aircraft marked in green in 2026 and the NASA 777 aircraft in blue planned for 2027. Examples of severe winter weather events include cold air outbreaks, windstorms, hazardous seas, snow and ice storms, sea ice breakup, and extreme precipitation. Data from the NURTURE mission will be used to inform first responders, decision makers, and the public sooner while also demonstrating the potential for NASA’s remote weather sensor capabilities to be developed for use on future space-based missions. “Effects from severe weather have significant costs that threaten lives and national security by destabilizing supply chains and damaging infrastructure,” said Steven Cavallo, principal investigator for NURTURE and lead scientist at the University of Oklahoma, School of Meteorology. The NURTURE mission is funded by NASA’s Earth Science Division and managed by researchers at NASA Langley and NASA Ames in collaboration with the University of Oklahoma.

Pagan Photojournal Navigation Science Photojournal Webb Data Reveals Dark Matter Photojournal Home Photojournal Search Latest Content Galleries Feedback RSS About Downloads Webb Data Reveals Dark Matter PNG (42.87 MB) This image from NASA’s James Webb Space Telescope, containing nearly 800,000 galaxies, is overlaid with a map of dark matter, represented in blue. Brighter blue areas indicate a higher density of dark matter. Researchers used Webb data to find the dark matter — which is invisible — via its gravitational influence on regular matter. The area of sky shown here is 0.54 square degrees (about 2½ times the size of the full Moon) and located in the constellation Sextans. Webb’s Near-Infrared Camera (NIRCam) peered at this region for a total of about 255 hours. Dark matter doesn’t emit, reflect, absorb, or even block light, and is therefore not visible to the human eye or traditional telescopes. But it does interact with the universe through gravity, and large clumps or clusters of dark matter have enough mass to curve space itself. Light traveling to Earth from distant galaxies becomes slightly distorted as it passes through the curved fabric of spacetime. In some cases, the warping is significant enough that it is apparent to the naked eye, almost as if the galaxy were being viewed through a warped windowpane, an effect called strong gravitational lensing. In the case of the dark matter map shown here, scientists inferred dark matter’s distribution by relying instead on an effect called weak gravitational lensing, which leads to much more subtle distortions of the light from thousands of galaxies. The dark matter in this area of sky was also mapped in 2007 using data from NASA’s Hubble Space Telescope. The Webb map contains about 10 times more galaxies than do maps of the area made by ground-based observatories and twice as many as Hubble’s map. It reveals new clumps of dark matter and captures a higher-resolution view compared to the Hubble map. Both the Hubble and Webb dark matter maps are part of a project called the Cosmic Evolution Survey (COSMOS). The full COSMOS “field” is 2 square degrees (about 10 times the size of the full Moon) and has been imaged by at least 15 telescopes in space and on the ground. Observing the same region with many different telescopes allows scientists to combine complementary views to understand how galaxies grow and how dark matter influences their evolution. Only Webb and Hubble data have been used to map dark matter in the region. To refine measurements of the distance to many galaxies for the map, the team used Webb’s Mid-Infrared Instrument (MIRI), designed and managed through launch by the agency’s Jet Propulsion Laboratory, along with other space- and ground-based telescopes. The wavelengths that MIRI detects also make it adept at detecting galaxies obscured by cosmic dust clouds. The James Webb Space Telescope 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 (********* Space Agency). Webb’s MIRI was developed through a 50-50 partnership between NASA and ESA. A division of Caltech in Pasadena, California, JPL led the U.S. contribution to MIRI. JPL also led development of MIRI’s cryocooler, done in collaboration with Northrop Grumman in Redondo Beach, California, and NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Jupiter’s moon Europa was captured by the JunoCam instrument aboard NASA’s Juno spacecraft during the mission’s close flyby on Sept. 29, 2022. The images show the fractures, ridges, and bands that crisscross the moon’s surface.Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing: Björn Jónsson (CC BY 3.0) Results from the solar-powered spacecraft provide a new measurement of the thickness of the ice shell encasing the Jovian moon’s ocean. Data from NASA’s Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter’s moon Europa. Using the spacecraft’s Microwave Radiometer (MWR), mission scientists determined that the shell averages about 18 miles (29 kilometers) thick in the region observed during Juno’s 2022 flyby of Europa. The Juno measurement is the first to discriminate between thin and thick shell models that have suggested the ice shell is anywhere from less than half a mile to tens of miles thick. Slightly smaller than Earth’s moon, Europa is one of the solar system’s highest-priority science targets for investigating habitability. Evidence suggests that the ingredients for life may exist in the saltwater ocean that lies beneath its ice shell. Uncovering a variety of characteristics of the ice shell, including its thickness, provides crucial pieces of the puzzle for understanding the moon’s internal workings and the potential for the existence of a habitable environment. The new estimate on the ice thickness in the near-surface icy crust was published on Dec. 17 in the journal Nature Astronomy. This artist’s concept depicts a cutaway view showing Europa’s ice shell. Data used to generate a new result on the ice thickness and structure was collected by the microwave radiometer instrument on NASA’s Juno during a close flyby of the Jovian moon on Sept. 29, 2022.NASA/JPL-Caltech/SwRI/Koji Kuramura/ Gerald Eichstädt (CC BY) Catching waves Although the MWR instrument was designed to investigate Jupiter’s atmosphere below the cloud tops, the novel instrument has proven valuable for studying the gas giant’s icy and volcanic moons as well. On Sept. 29, 2022, Juno came within about 220 miles (360 kilometers) of Europa’s frozen surface. During the flyby, MWR collected data on about half the moon’s surface, peering beneath the ice to measure its temperatures at various depths. “The 18-mile estimate relates to the cold, rigid, conductive outer-layer of a pure water ice shell,” said Steve Levin, Juno project scientist and co-investigator from NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission. “If an inner, slightly warmer convective layer also exists, which is possible, the total ice shell thickness would be even greater. If the ice shell contains a modest amount of dissolved salt, as suggested by some models, then our estimate of the shell thickness would be reduced by about 3 miles.” The thick shell, as suggested by the MWR data, implies a longer route that oxygen and nutrients would have to travel to connect Europa’s surface with its subsurface ocean. Understanding this process may be relevant to future studies of Europa’s habitability. Cracks, pores The MWR data also provides new insights into the makeup of the ice just below Europa’s surface. The instrument revealed the presence of “scatterers” — irregularities in the near-surface ice such as cracks, pores, and voids that scatter the instrument’s microwaves reflecting off the ice (similar to how visible light is scattered in ice cubes). These scatterers are estimated to be no ******* than a few inches in diameter and appear to extend to depths of hundreds of feet below Europa’s surface. The small size and shallow depth of these features, as modeled in this study, suggest they are unlikely to be a significant pathway for oxygen and nutrients to travel from Europa’s surface to its salty ocean. “How thick the ice shell is and the existence of cracks or pores within the ice shell are part of the complex puzzle for understanding Europa’s potential habitability,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “They provide critical context for NASA’s Europa Clipper and the ESA (European Space Agency) Juice (JUpiter ICy moons Explorer) spacecraft — both of which are on their way to the Jovian system.” Europa Clipper will arrive there in 2030, while Juice will arrive the year after. Juno will carry out its 81st flyby of Jupiter on Feb. 25.  More about Juno A division of Caltech in Pasadena, California, JPL manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Athena, NASA’s newest supercomputer, is housed at the agency’s Modular Supercomputing Facility at NASA’s Ames Research Center in California’s Silicon Valley.NASA/Brandon Torres-Navarrete NASA is announcing the availability of its newest supercomputer, Athena, an advanced system designed to support a new generation of missions and research projects. The newest member of the agency’s High-End Computing Capability project expands the resources available to help scientists and engineers tackle some of the most complex challenges in space, aeronautics, and science. Housed in the agency’s Modular Supercomputing Facility at NASA’s Ames Research Center in California’s Silicon Valley, Athena delivers more computing power than any other NASA system, surpassing the capabilities of its predecessors, Aitken and Pleiades, in power and efficiency. The new system, which was rolled out in January to existing users after a beta testing *******, delivers over 20 petaflops of peak performance – a measurement of the number of calculations it can make per second – while reducing the agency’s supercomputing utility costs. “Exploration has always driven NASA to the edge of what’s computationally possible,” said Kevin Murphy, chief science data officer and lead for the agency’s High-End Computing Capability portfolio at NASA Headquarters in Washington. “Now with Athena, NASA will expand its efforts to provide tailored computing resources that meet the evolving needs of its missions.” Supercomputers like Athena are critical to missions and research across the agency, providing the computational power necessary to simulate rocket launches, design next-generation aircraft, and train large-scale artificial intelligence foundation models capable of analyzing massive datasets to uncover new scientific insights. The supercomputer is available to NASA researchers and external scientist and researchers supporting NASA programs who can apply for time to use the system. The name Athena was selected through a contest held in March 2025 among the agency’s High-End Computing Capability workforce, which chose the name of the Greek goddess of wisdom and warfare because she is the half-sister of Artemis. Managed by NASA’s Office of the Chief Science Data Officer, the High-End Computing Capability portfolio supports a flexible, hybrid computing approach that combines supercomputers with access to other tools, such as commercial cloud platforms. This strategy enables NASA teams to choose the most effective computing environment for their research, whether running complex simulations, developing and deploying AI models, or performing large-scale data analysis. The project’s capabilities will continue to expand as the agency invests in advanced supercomputing to meet the growing complexity of its missions. As exploration pushes further into the universe, the ability to compute quickly, efficiently, and intelligently will be more important than ever. With Athena, NASA is laying the digital foundation for the next era of discovery.

NASA, ESA, CSA, STScI, Klaus Pontoppidan (NASA-JPL), Joel Green (STScI); Image Processing: Alyssa Pagan (STScI) The NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope captured the actively forming protostar EC 53 (circled at left) in the Serpens Nebula in this image released on Jan. 21, 2026. Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these “dirty snowballs” spend most of their time in the ultracold Kuiper Belt and Oort Cloud. Now, looking outside our solar system, Webb has returned the first conclusive evidence that links how those conditions are possible. The telescope clearly showed for the first time that the hot, inner part of the disk of gas and dust surrounding a very young, actively forming star is where crystalline silicates are forged. Webb also revealed a strong outflow that is capable of carrying the crystals to the outer edges of this disk. Compared to our own fully formed, mostly dust-cleared solar system, the crystals would be forming approximately between the Sun and Earth. Read more about this discovery.

3 min read NASA, Partners Advance LISA Prototype Hardware Engineers and scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, completed tests this month on a second early version of a key element of the upcoming LISA (Laser Interferometer Space Antenna) mission. The LISA mission, a collaboration between ESA (the European Space Agency) and NASA, will use infrared lasers to detect gravitational waves, or ripples in the fabric of space-time. The tests involved the frequency reference system, delivered by BAE Systems, that will help control the lasers connecting LISA’s three spacecraft. The lasers must be finely tuned to make precise measurements — to within a trillionth of a meter, called a picometer. A prototype laser optical module for LISA (Laser Interferometer Space Antenna) rests on a table after testing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in May 2025. Xiaozhen Xu, an engineer with Miller Engineering and Research Corp., works in the background. The smaller box to the right is the laser electronics module. Each of the three LISA spacecraft will have a laser system with a frequency reference component and six laser heads.

A prototype charge management device for LISA sits on a lab bench at NASA Goddard in May 2025. Each of the three LISA spacecraft will have a charge management device to reduce the buildup of electric charge on the gold-platinum proof masses that fly freely inside the spacecraft. The University of Florida in Gainesville and Fibertek Inc. in McNair, Va., are developing the devices. NASA/Dennis Henry NASA’s contributions are part of the agency’s efforts to innovate on ambitious science missions that will help us better understand how the universe works. LISA will also offer a major advancement in multimessenger astronomy, which is how scientists explore cosmic signals other than light. The three LISA spacecraft will fly in a vast triangular formation that follows Earth as it orbits the Sun. Each arm of the triangle will stretch 1.6 million miles (2.5 million kilometers). Each spacecraft will contain two free-floating cubes inside called proof masses. Arriving gravitational waves from throughout the universe will minutely change the lengths of the triangle’s arms. The lasers connecting the cubes will measure changes in their separation to within a distance smaller than a helium atom. In May 2024, technicians inspected the prototype LISA telescope in a darkened clean room at NASA Goddard. Illuminated by a flashlight, the telescope’s structure glows. The prototype is made from a translucent, amber-colored, glass-ceramic material called Zerodur, which is often used in high-precision applications because it resists changes in shape over a wide temperature range. The mirror, near center and coated in gold, reflects a magnified image of part of the telescope. NASA/Dennis Henry The enormous scale of the triangle will enable LISA to detect gravitational waves that cannot be found with ground-based facilities, such as those generated when massive ****** holes in the centers of galaxies merge. Scientists can use the data to learn about a source’s distance and physical properties. The LISA mission is slated to launch in the mid-2030s.

But even by local standards, the deluge in January 2026 was remarkable for its scale and severity. In December and January, weeks of intense rain swelled rivers and overwhelmed key reservoirs, sending floodwaters spilling into heavily populated areas along the Limpopo and Incomati rivers. The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Aqua satellite captured this false-color image (bands 7-2-1) of floodwaters coursing down the two rivers on January 25, 2026 (right). The image on the left, captured by the Terra satellite, shows the same area on December 17, 2025, before the flooding. A natural-color version of the image shows thick plumes of water rich in suspended sediment flowing down the rivers and into the Mozambique Channel. Flooding has affected at least 600,000 people, displaced hundreds of thousands, and destroyed or damaged at least 30,000 homes, according to Mozambique’s National Disasters Management Institute, though it’s likely the numbers will increase due to ongoing search and rescue operations. Some of the hardest-hit cities include Maputo, Xai-Xai, and Chókwè. Agriculture officials report the flooding of at least 180,000 hectares (440,000 acres) of crops and the loss of more than 150,000 head of livestock. Health experts are warning of elevated risk of cholera, diarrhea, and other waterborne diseases, and authorities from at least one city have reported crocodile attacks.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Research from NASA and GE Aerospace led to the successful testing of a jet engine at the company’s Peebles Test Operation site in Ohio in December. The hybrid engine is a modified version of a GE Aerospace Passport.GE Aerospace To an untrained eye, the aircraft engine sitting outside of a Cincinnati facility in December might have looked like standard hardware. But NASA and GE Aerospace researchers watching the unit fire up for a demonstration knew what they were looking at: a hybrid engine performing at a level that could potentially power an airliner. It’s something new in the aviation world, and the result of years of research and development. NASA, GE Aerospace, and others working toward hybrid engine development had already tested components in the past — power system controls, electric motors, and more. What the demonstration at GE Aerospace’s Peebles Test Operation site in Ohio represented was the first test of an integrated system. “Turbines already exist. Compressors already exist. But there is no hybrid-electric engine flying today. And that’s what we were able to see,” said Anthony Nerone, who served as manager of the agency’s Hybrid Thermally Efficient Core (HyTEC) project at NASA’s Glenn Research Center in Cleveland during the test engine’s development. The test involved a modified GE Aerospace’s Passport engine with the ability to extract energy from some of its operations and insert that supplementary power into other parts. The hybrid engine is result of research from GE Aerospace and NASA under a cost-sharing HyTEC contract. It runs on jet fuel with assistance from electric motors, a concept that seems simple in a world where hybrid cars are common. Yet the execution was complex, requiring researchers to invent, adapt, and integrate parts into a system that could deliver the requisite power needed for a single-aisle aircraft safely and reliably. As a result, the demonstration — known as a power extraction test — was one of the most complex GE Aerospace has staged to date. “They had to integrate equipment they’ve never needed for previous tests like this,” said Laura Evans, acting HyTEC project manager at Glenn. Despite the complexity, the team witnessed a successful demonstration. Not a balancing test or a preliminary exercise, but an engine on a mount doing many of the things it would need to do if installed in an aircraft. The test comes at a time when U.S. aviation is increasingly looking for power systems that can do more while also saving money on fuel. It’s a trend NASA was well ahead of. Hybrid aircraft engine technology began to emerge from Glenn roughly 20 years ago, when it seemed nearly impossible to realize, Nerone said. “Now,” he said. “When you go to a conference, hybrid technology is everywhere.” And NASA and GE now have real data for how the technology can be applied to flight. From that early start, NASA transitioned into HyTEC and its contract with GE Aerospace. HyTEC’s goal is to mature technology that will enable a hybrid engine that burns up to 10% less fuel compared to today’s best-in-class engines. NASA’s overall goal is to leverage its resources to bring the technology to market faster, meeting industry needs. The work is far from over. Both NASA and GE Aerospace are analyzing data from the demonstration and from previous work and are making progress toward a compact engine test this decade. Still, the demonstration was a chance to see the integration of technology that’s closer than ever to practical application. “We’re getting close to the payoff on work that’d been in progress for a long time,” Nerone said.

Credit: NASA The Sultanate of Oman signed the Artemis Accords during a ceremony in Muscat attended by NASA on Monday, becoming the 61st nation to commit to responsible space exploration for the benefit of all humanity. “Oman’s accession to the Artemis Accords sets an important example about the value of responsible behavior and shared pursuit of discovery,” said NASA Administrator Jared Isaacman in recorded remarks during the ceremony. “Oman joins the U.S. and our other partners on ensuring the peaceful exploration of space for generations to come. We are returning humans to the Moon and laying the groundwork for future missions. A community of like-minded nations will be the foundation of our success.” U.S. Ambassador to the Sultanate of Oman Ana Escrogima and NASA’s Deputy Associate Administrator Casey Swails participated in the event held on the opening day of the Middle East Space Conference, an international forum on space and innovation in the region. Said al-Maawali, Oman’s minister of transportation, communication, and information technology signed on behalf of the country. In 2020, during the first Trump Administration, the United States, led by NASA and the U.S. Department of State, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. The accords introduced the first set of practical principles aimed at enhancing the safety, transparency, and coordination of civil space exploration on the Moon, Mars, and beyond. Signing the Artemis Accords means to explore peaceably and transparently, to render aid to those in need, to enable access to scientific data that all of humanity can learn from, to ensure activities do not interfere with those of others, to preserve historically significant sites and artifacts, and to develop best practices for how to conduct space exploration activities for the benefit of all. More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.
