NASA Connects Little Red Dots with Chandra, Webb
A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years.
A “X-ray dot” found by NASA’s Chandra X-ray Observatory could explain what the hundreds or potentially thousands of these objects are. A paper describing the results published in The Astrophysical Journal Letters.
Shortly after NASA’s James Webb Space Telescope started its science observations, reports of a new class of mysterious objects emerged. Astronomers found small, red objects about 12 billion light-years from Earth or farther, which became known as “little red dots” (LRDs).
Many scientists think LRDs are supermassive black holes embedded in clouds of dense gas, which mask some of the typical signatures in different kinds of light – including X-rays – that astronomers usually use to identify them. This would make them different from typical growing supermassive black holes, which are not embedded in dense gas, allowing bright ultraviolet light and X-rays from material orbiting the black holes to escape.
Because of this and their potential similarities to stellar atmospheres, astronomers have called this the “black hole star” scenario for LRDs.
This new “X-ray dot” (officially known as 3DHST-AEGIS-12014), which is located about 11.8 billion light-years from Earth, may provide a crucial bridge between black hole stars and typical growing supermassive black holes. It exhibits most of the features of an LRD, including being small, red, and located at a vast distance, but it glows in X-ray light, unlike other LRDs.
“Astronomers have been trying to figure out what little red dots are for several years,” said lead author Raphael Hviding of the Max Planck Institute for Astronomy in Germany. “This single X-ray object may be – to use a phrase – what lets us connect all of the dots.”
Artist’s Illustration of a Close-Up View of X-ray Dot, 3DHST-AEGIS-12014. NASA/CXC/SAO/M. Weiss; adapted by K. Arcand & J. MajorThe team found this one special object after comparing new data from Webb with a deep survey previously performed by Chandra.
“If little red dots are rapidly growing supermassive black holes, why do they not give off X-rays like other such black holes?” said co-author Anna de Graaff of the Center for Astrophysics | Harvard & Smithsonian, in Cambridge, Massachusetts. “Finding a little red dot that looks different from the others gives us important new insight into what could power them.”
The researchers suggest that the X-ray dot represents a transition phase from an LRD to a typical growing supermassive black hole. As the black hole star consumes its surrounding gas, patchy holes in the clouds of gas appear. This allows X-rays from material falling onto the black hole to poke through, which are observed by Chandra. Eventually all the gas is consumed, and the black hole star ceases to exist.
There are also hints in the Chandra data of the X-ray dot that there are variations in X-ray brightness, which supports the idea that the black hole is partly obscured. As the cloud of gas rotates, patches of denser and less dense gas can move across the black hole, causing changes in X-ray brightness.
“If we confirm the X-ray dot as a little red dot in transition, not only would it be the first of its kind, but we may be seeing into the heart of a little red dot for the first time,” said co-author Hanpu Liu of Princeton University in New Jersey. “We would also have the strongest piece of evidence yet that the growth of supermassive black holes is at the center of some, if not all, of the little red dot population.”
An alternate idea for the X-ray dot is that it is a more common type of growing supermassive black hole but is veiled in an exotic type of dust that astronomers have not seen before. Future observations are planned that should be able to shed light on the truth.
“The X-ray dot had been sitting in our Chandra survey data for over ten years, but we had no idea how remarkable it was before Webb came along to observe the field,” said co-author Andy Goulding of Princeton. “This is a powerful example of collaboration between two great observatories.”

There’s No Place Like NASA’s New X-59 Hangar Home
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s X-59 quiet supersonic airplane sits parked in front of its new hangar home at the agency’s Armstrong Flight Research Center in California. The facility originally was constructed in 1968 and for nearly 60 years has hosted a number of research aircraft and programs.NASA/Christopher LC ClarkThere’s no sign reading “home sweet home” in the hangar where the X‑59 now sits, but the sentiment is unmistakable among those tending to the quiet supersonic aircraft.
Located at NASA’s Armstrong Flight Research Center in Edwards, California, the X-59 hangar was built in 1968 but looks like new thanks to a full renovation and modernization. While the X-59 was being assembled in Palmdale, California, workers at NASA Armstrong gutted the hangar, adding new electrical wiring, a fire suppression system, office space, air conditioning, and other safety features.
“The whole team is incredibly proud of what we’ve accomplished in preparing this new home for the X-59,” said Bryan Watters, the NASA project manager at Armstrong who led the renovation effort. “The fact we could take a 1960s hangar and modernize it for use by a 2020’s X-plane is very special.”
The X-59 is the centerpiece of NASA’s Quesst mission to enable a new era of commercial supersonic air travel over land by reducing the sound of typically loud sonic booms to a much quieter sonic thump.
Home huntingWhen NASA test pilot Nils Larson successfully took the X-59 into the air for the first time on Oct. 28, 2025, he flew from the Lockheed Martin Skunk Works assembly site in Palmdale to nearby NASA Armstrong, from where test flights have continued to make progress.
From the beginning of the program, knowing the X-59 would eventually need a new residence at NASA Armstrong, Quesst managers were on the hunt for somewhere to house the quiet supersonic demonstrator.
Like anyone looking for the ideal place to call home, the team made sure there would be enough space for the airplane and all its support equipment. But with the experimental jet measuring at just under 100 feet long and 30 feet wide, there were few options.
“We had to find a hangar that was long enough so that part of the X-59 wouldn’t hang outside, exposed to the elements,” Watters said.
Building 4826, as the hangar is officially designated, turned out to be the choice spot. “It was basically stripped down and gutted so that essentially it was just structural steel with siding. From that state it was rebuilt,” Watters said.
The feature they are perhaps most proud of is the hangar’s new floor. Covering more than 32,000 square feet, it is coated with epoxy that prevents any spills from seeping into the concrete.
From the hangar’s office windows, the view of the hangar floor can include the F-15 research jets that will be used as chase planes to support X-59 flights in the coming months. The renovation faced challenges along the way, chief among them being supply chain issues stemming from the COVID-19 pandemic. But there were some incredible, unforgettable moments too.
Circa 1990 Nov. 2025 On loan to NASA from the Air Force, an F-15 Eagle fighter jet was the focus of the Short Takeoff and Landing/Maneuver Technology Demonstrator research program, which concluded in 1991. The aircraft is seen here inside Building 4826, a hangar at NASA’s Armstrong Flight Research Center that was renovated and began use in 2025 as home for the X-59 quiet supersonic technology demonstrator.NASA NASA’s X-59 quiet supersonic technology demonstrator aircraft is seen parked inside its new hangar home at the agency’s Armstrong Flight Research Center in California.NASA/Christopher LC Clark Circa 1990Nov. 2025 On loan to NASA from the Air Force, an F-15 Eagle fighter jet was the focus of the Short Takeoff and Landing/Maneuver Technology Demonstrator research program, which concluded in 1991.

Hangar Updated to Continue Hosting Historic Research CurtainToggle2-Up Image Details This NASA hangar at Armstrong Flight Research Center originally was constructed in 1968 and since then has hosted a number of history-making programs. Compare the two images above to see how the hangar looked during the late 1980s when it hosted an F-15 research aircraft (left), and beginning in 2025 after it had been renovated and modernized to host the X-59 quite supersonic technology demonstrator aircraft. Moved inWith X-59 now flying regularly and comfortably settled into its new digs, the Quesst team is gauging its performance on the way to quiet supersonic flight.
“This is truly a great time for Quesst and the X-59,” said Cathy Bahm, NASA’s project manager for the Low Boom Flight Demonstrator. “It’s also still a little surreal to be able to just walk down from your office and see the airplane in our hangar.”
For more than a year, the hangar refurbishment team worked through every detail of the X-59’s new home to make sure it would be safe and sound. But actually seeing the aircraft occupy that space is an adjustment for them, too.
“We’ve looked at X-59 models on our desk for years and then, you know, there’s the real thing right in front of us, in a hangar that we renovated,” Watters said.
A real thing in the hangar – and streaking across the California desert sky. The X-59’s transition from an idea into a working aircraft is a testament to the teams that help build out every aspect of its infrastructure.
NASA’s X-59 is supported under the agency’s Aeronautics Research Mission Directorate.

By Earth Resources Observation and Science (EROS) Center
For more than 50 years, Landsat has imaged Earth’s land and near-shore surfaces as the satellites descend in midmorning orbit, when daily sunlight is optimal. That’s just what they’ve always done.
Currently, Landsat 8 and Landsat 9 circle the globe while also making better use of their ascending paths, peering into the darkness for special requests.
The visible spectral bands of Landsat—the same blue, green and red wavelength colors our eyes can see—are typically not that useful when collected on the ascending orbit node (also known as “nighttime imagery”). The exception is twilight or darkness at Earth’s poles, which can provide a surprisingly clear observation in the thermal infrared spectral bands where snow, ice and water temperatures can be retrieved when the sun is at or below the horizon.
Through the dark, shortwave infrared (SWIR) bands within Landsat’s Operational Land Imager (OLI) instrument can detect intense heat sources such as volcanoes or active fires, while the Thermal Infrared Sensor (TIRS) measures surface temperatures that range from geothermal geysers to solid ice.
There is a growing interest in seeing what Landsat can capture as it ascends over the dark side of Earth, according to Dr. Christopher Crawford, the Landsat Project Scientist at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center. Crawford leads and oversees Landsat’s long-term Earth data acquisition strategy for the USGS.
“I’ve seen a noticeable uptick in the number of nighttime imaging special requests. That’s a very active and innovative measurement science area for Landsat right now,” Crawford said.
“We have active volcanoes, we’ve got an ice environment that’s changing, and wildfire occurrences are increasingly growing into hazards that threaten human safety, infrastructure and wildlife, among other issues. Nighttime imaging is an all-purpose solution, kind of like Jiffy Baking Mix.”
R. Greg Vaughan of the USGS Astrogeology Science Center does field work at Yellowstone National Park. USGS photo Sources/Usage: Public Domain Keeping an Eye on Volcanoes and YellowstoneA particular request for nighttime imagery that turned into a “systematic observation,” Crawford said, is Yellowstone National Park. The volcanic area’s 10,000 thermal features, such as geysers or hot springs or steam vents, can get hotter or colder, and they can appear or disappear.
Crawford is fascinated by volcanoes in general and recognizes the value of imaging them day and night. After Landsat 9 launched in 2021, when two satellites with the same high-quality sensors would together yield an image of each area of land every eight days, it seemed like a good time to start a consistent annual campaign to capture active volcanoes at night, he said.

R. Greg Vaughan of the USGS Astrogeology Science Center, who researches active volcanoes, gave him a list. Vaughan has used Landsat data and other remote sensing methods to monitor changing thermal features in his role as the remote sensing lead for the Yellowstone Volcano Observatory.
Vaughan also taught Crawford something about imaging Yellowstone’s thermal features at night—that the best season for locating them is during winter. That’s when the contrast between the heated features and the colder surrounding area is greatest.
“The thing that I’ve probably taken away the most is that you have to acquire data to then understand what data to continue to acquire,” Crawford said.
Vaughan spotted an exciting surprise when reviewing Landsat 8 nighttime TIRS data of Yellowstone acquired in April 2017. Comparing warm areas in the imagery to previously mapped thermal features, he found a “big blob of bright, warm pixels” that didn’t match anything on the map.
After ruling out the possibility that it could be a thawing lake next to frozen land, he looked at the secluded area with daytime aerial imagery. The telltale signs of a new and growing thermal feature were there: bright hydrothermal-altered soil and dead and dying trees.
A Landsat 8 nighttime thermal infrared image from April 2017 shows the Tern Lake area in Yellowstone National Park. In Yellowstone, temperatures are extremely cold at night in the winter, and most lakes are frozen (dark pixels). West Tern Lake seems to be thawing here; it might receive some thermal water inflow from nearby hot springs. The patch of bright (warm) pixels between West Tern Lake and the Tern Lake Thermal Area emerged over a period of roughly 20 years. Lakes are outlined in blue; known thermal areas are outlined in red; and the red triangles are individual thermal features that have been mapped. Image credit: R. Greg Vaughn, USGSVaughan discussed his find and his use of Landsat data in a recent Eyes on Earth podcast episode produced by USGS EROS.
“This is why I love Landsat 8 and 9 so much. These instruments acquire data regularly, not just during the day, but they can also be tasked to acquire data at night on a regular basis. And this is really critical for my work,” Vaughan said.
Vaughan has been named a member of the current Landsat Science Team, a group of scientific and technical subject matter experts who provide analysis and advice to the Landsat Program. His research in that capacity will focus on active volcanoes.
An aerial view of the area in the Landsat 8 nighttime image shows the new thermal area (center left) that R. Greg Vaughan spotted in the Landsat image. The existing Tern Lake Thermal Area is the bright white patch of ground in the upper middle part of the image. West Tern Lake is the dark area in the lower right, and Tern Lake is above that. Photo credit: Michael Poland, USGS Fires, Flares and Urban Areas Among RequestsThe fire community in the western United States also finds value in Landsat nighttime imagery, Crawford said—including the energy industry and its infrastructure.
The Department of Energy’s Pacific Northwest National Laboratory submits annual special requests for proactive nighttime imaging of seasonal wildfires to support on-the-ground decision making.
“We’ve done it three seasons in a row, and the results are pretty remarkable in terms of what we’re able to see,” especially with the SWIR bands, Crawford said. Those results compare well to airborne infrared sensing taken from low-altitude flights over the same wildfires.
Landsat can also detect gas flares that are useful to oil and gas industry functions. “There are regular special requests submitted to monitor global sites that produce Liquefied Natural Gas, or LNG,” Crawford said.
In addition, he sees requests for nighttime images over particular cities to map urban temperature, which may be higher than cooler surrounding areas.
One recent request went beyond the already routine monitoring of active volcanoes in Iceland to encompass the entire country and coastline in a large seasonal campaign to survey overall volcanic activity.
Crawford weighs this type of request carefully, posing these questions: “Does this advance the science mission? Is it serving the user community?”
For Iceland, that was a yes.
“I look for areas where Landsat imaging data may be underutilized, as well as areas for strategic science mission advancement and societal benefits, and in many ways, these growth areas can be enabled through the data acquisition process,” Crawford said.
Landsat 8’s thermal infrared, shortwave infrared and near infrared spectral bands expose the Caldor Fire’s advancing edge south of Lake Tahoe in California in a nighttime image from August 29, 2021. A LEAP ForwardA significant advancement in learning about Landsat’s nighttime capabilities came with the effort to monitor polar regions year-round, with leadership from former Landsat Science Team member Dr. Ted Scambos from the University of Colorado Boulder.
The Landsat Extended Acquisition of the Poles (LEAP) campaign now routinely collects imagery over the polar regions, where few wintertime images had existed in Landsat’s data record before. The visible-to-shortwave infrared and thermal infrared spectral bands allow scientists to track changes in polar ice sheets, measure polar surface temperatures and examine the interaction of ocean water and ice shelves.
The sun’s low angle is not much of a hindrance to imaging data quality, Crawford said in an Eyes on Earth episode about the LEAP campaign. “Snow and ice are still really bright mediums on the surface, and so even if the illumination is low, you can still see a lot of detail because of the high reflectivity.”
Fortunately, nighttime imaging does not burden Landsat 8 and Landsat 9. “The instruments are always on, so it’s just a matter of whether we’re recording the data,” Crawford said.
This twilight thermal infrared image of Petermann Glacier, Greenland, was captured by Landsat 9 on January 5, 2024. This winter image displays data acquired when the sun was below the horizon. Darker areas are relatively colder than bright areas.The imagery’s darkness helps keep data volumes much lower than the daytime and allows sufficient time for the satellites to pass off the data to ground stations around the globe whose function is to downlink the recorded data.
“We’re starting to leverage Landsat 8 and Landsat 9 observatory capabilities to maximum scientific and societal benefit returns,” Crawford said.
“We’re populating the Landsat archive with long-term image data records that are helpful for not only quantifying changes on the Earth’s surface right now, but in the past and in the future.”

Description
NASA’s Curiosity Mars rover captured this 360-degree view of a region filled with low ridges called boxwork formations between Nov. 9 and Dec. 7, 2025 (the 4,714th to 4,741st Martian days, or sols, of the mission). At 1.5 billion pixels, this is one of the largest panoramas Curiosity has ever taken (the rover’s largest panorama of all time is 1.8 billion pixels). This newer panorama is made up of 1,031 individual images captured by Curiosity’s Mastcam using its right camera, which has a 100-millimeter focal length lens. The images were later sent to Earth and stitched together into the full panorama.
The images were taken at a ridgetop site nicknamed “Nevado Sajama,” where Curiosity collected a rock sample using a drill on the end of its robotic arm. Since May 2025, Curiosity has been exploring a region full of geologic formations called boxwork, which crisscross the surface for miles and look like giant spiderwebs when viewed from space. The new panorama shows them as they really are: low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall and about 30 feet (9 meters) across with sandy hollows in between.
Figure AFigure A is a high-resolution version of this panorama (1.8 gigabytes).
Figure BFigure B is a lower-resolution version of the panorama (276 megabytes) captured by Mastcam’s left camera, which has a 34-millimeter focal length lens. This version includes the rover’s deck, which is often left out of such imagery in order to reduce the amount of data relayed back to Earth.
Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington as part of NASA’s Mars Exploration Program portfolio. Malin Space Science Systems in San Diego built and operates Mastcam.

NASA Fires Up Powerful Lithium-Fed Thruster for Trips to Mars
A technology that could propel crewed missions to Mars and robotic spacecraft throughout the solar system was recently put to the test at NASA’s Jet Propulsion Laboratory in Southern California. On Feb. 24, for the first time in years and at power levels exceeding any previous test in the United States, a team fired up an electromagnetic thruster that runs on lithium metal vapor.
This prototype achieved power levels beyond the highest-power electric thrusters on any of the agency’s current spacecraft. Valuable data from the first firing of this thruster will help inform an upcoming series of tests.
“At NASA, we work on many things at once, and we haven’t lost sight of Mars. The successful performance of our thruster in this test demonstrates real progress toward sending an American astronaut to set foot on the Red Planet,” said NASA Administrator Jared Isaacman. “This marks the first time in the United States that an electric propulsion system has operated at power levels this high, reaching up to 120 kilowatts. We will continue to make strategic investments that will propel that next giant leap.”
JPL senior research scientist James Polk peers into the condensable metal propellant (CoMeT) vacuum facility at JPL’s Electric Propulsion Lab, where a high-power electric thruster prototype his team developed was being put to the test in February 2026.NASA/JPL-CaltechDuring five ignitions, the tungsten electrode at the thruster’s center glowed bright white, reaching over 5,000 degrees Fahrenheit (2,800 degrees Celsius). The work was conducted in JPL’s Electric Propulsion Lab, home to the condensable metal propellant vacuum facility, a unique national asset for safely testing electric thrusters that use metal vapor propellants at up to megawatt-class power levels.
Powering upElectric propulsion uses up to 90% less propellant than traditional, high-thrust chemical rockets. Current electric propulsion thrusters, like those powering NASA’s Psyche mission, use solar power to accelerate propellants, producing a low, continuous thrust that reaches high speeds over time. NASA JPL is testing a lithium-fed magnetoplasmadynamic (MPD) thruster, a technology that has been researched since the 1960s but never flown operationally. The MPD engine differs from existing thrusters by using high currents interacting with a magnetic field to electromagnetically accelerate lithium plasma.
The prototype thruster is enclosed in JPL’s condensable metal propellant (CoMeT) vacuum facility, a unique national asset designed to safely test thrusters using metal-vapor propellants as part of potential megawatt-class electric propulsion systems.NASA/JPL-CaltechDuring the test, the team achieved power levels of up to 120 kilowatts. That’s over 25 times the power of the thrusters on Psyche, which is currently operating the highest-power electric thrusters of any NASA spacecraft. In the vacuum of space, the gentle but steady force Psyche’s thrusters provide over time accelerates the spacecraft to 124,000 mph.
“Designing and building these thrusters over the last couple of years has been a long lead-up to this first test,” said James Polk, senior research scientist at JPL. “It’s a huge moment for us because we not only showed the thruster works, but we also hit the power levels we were targeting. And we know we have a good testbed to begin addressing the challenges to scaling up.”
Going electricTo view the test, Polk peered through a small portal into the 26-foot-long (8-meter-long) water-cooled vacuum chamber. Inside, the thruster flared to life, its nozzle-shaped outer electrode glowing incandescent as it emitted a vibrant red plume. Polk has researched lithium-fed MPD thrusters for decades, having worked on NASA’s Dawn mission and the agency’s Deep Space 1, the first demonstration of electric propulsion beyond Earth orbit.
The team aims to reach power levels between 500 kilowatts and 1 megawatt per thruster in coming years. Because the hardware operates at such high temperatures, proving the components can withstand the heat over many hours of testing will be a key challenge. A human mission to Mars might need 2 to 4 megawatts of power, requiring multiple MPD thrusters, which would have to operate for more than 23,000 hours.
Lithium-fed MPD thrusters have the potential to operate at high power levels, use propellant efficiently, and provide significantly greater thrust than currently flying electric thrusters. Fully developed and paired with a nuclear power source, they could reduce launch mass and support payloads required for human Mars missions.
The MPD thruster work, in development for the past 2½ years, is led by JPL in collaboration with Princeton University in New Jersey and NASA’s Glenn Research Center in Cleveland. It is funded by NASA’s Space Nuclear Propulsion project, which in 2020 began supporting a megawatt-class nuclear electric propulsion program for human Mars missions by focusing on five critical technology elements, of which the electric propulsion subsystem is one. The project, based at the agency’s Marshall Space Flight Center in Huntsville, Alabama, is part of the NASA’s Space Technology Mission Directorate.

NASA Laser Terminal Enhances Views During Artemis II Mission
Millions of people watched the historic launch of Artemis II and were captivated by the mission’s 10-day journey around the Moon as NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen ventured farther into space than any human before. Part of the public’s ability to experience the mission in high-definition was due to laser communications.

An animation depicting the Orion capsule using infrared light. Although infrared light is shown here, it is actually invisible to the human eye.NASA/Dave RyanLaser, or optical, communications systems use invisible infrared light to transmit more data in a single downlink than traditional radio frequency systems. During Artemis II, NASA tested an optical communications system to demonstrate the benefits laser communications can bring to future human spaceflight missions to the Moon.
The optical terminal, a payload attached to the Orion spacecraft’s exterior, marked the first time laser communications supported a crewed mission at lunar distance. The terminal collected and transmitted high-definition video, flight procedures, photos, engineering and science data, and voice communications to Earth over laser signals when the spacecraft had line of sight with ground terminals.
The Orion capsule showing the Orion Artemis II Optical Communications System (O2O). O2O was developed by the Massachusetts Institute of Technology Lincoln Laboratory in Lexington, Massachusetts. NASA“Access to high-resolution imagery and other scientific data during dynamic science mission phases is a game changer,” said Dr. Kelsey Young, Artemis II lunar science lead. “It means faster insights, better science decision-making to support the crew as they’re completing science exploration, and a mission with a more integrated science presence. It felt like we were right there with the crew, and it maximized the lunar science impact of the mission as it allowed for a more productive crew science conference the morning after the flyby.”

Artemis II Lunar Science Lead
During the about 10-day journey, the laser communications system exchanged 484 gigabytes of data between Orion and Earth, roughly equivalent to 100 high-definition movies compared to the capacity of standard radio frequency systems. The crisp, clear photos of Earthset, Earthrise, and many of the other mission images were downlinked over the Orion Artemis II optical communication system’s laser links. The terminal also was able to transmit data to the Orion capsule, delivering information to the crew.
The solar eclipse captured from a camera mounted on one of the Orion spacecraft’s solar array wings during the Artemis II crew’s flyby of the Moon’s far side.NASAArtemis II’s primary communications support came from the Near Space Network and Deep Space Network, NASA’s traditional radio frequency systems. At lunar distances, with the current processing structure, these systems were limited to single-digit data rates in the megabits per second range. When the optical system was in use, the Orion crew module established multiple 260 megabits per second downlinks, surpassing many of its demonstration goals.
On Earth, NASA ground station telescopes at the NASA’s Jet Propulsion Laboratory in Southern California and White Sands Complex in New Mexico were selected for their high-altitude, dry environments to ensure a strong link between Earth and the optical terminal aboard Orion. These stations collected the bulk of Orion’s optical signals, hitting a record of 26 gigabytes of data received, downloaded, and transmitted to mission control in under an hour – enabling faster data transfer than most home internet capabilities.
This video from the NASA broadcast shows the Orion feed switching from the radio frequency link over to the optical link and the change in clarity.In addition to NASA’s two main ground stations, Orion also downlinked data to a newly developed site at the Australian National University Quantum Optical Ground Station at Mount Stromlo in Canberra, Australia. After several years of technical support, subject matter experts from NASA’s Glenn Research Center in Cleveland and the agency’s Goddard Space Flight Center in Greenbelt, Maryland, worked with the university to build and demonstrate a lunar-capable optical telescope leveraging affordable parts developed by commercial industry.

The ground station successfully downlinked the terminal’s highest possible data rate of 260 megabits per seconds, proving that commercial, off-the-shelf parts can be leveraged to decrease the cost, time, and difficulty required to assemble optical ground stations.
Space communications isn’t just about moving bytes, it’s about delivering the images, the video, and the voices of the crew that bring a mission to life.Greg Heckler
SCaN Deputy Program Manager for Capability Development
“Space communications isn’t just about moving bytes, it’s about delivering the images, the video, and the voices of the crew that bring a mission to life,” said Greg Heckler, SCaN’s deputy program manager for capability development. “With the optical payload, we were able to watch astronauts embark on their journey in near real-time. Those moments gave us a breathtaking new view of Earth and revealed the crew isn’t just a team, but a family.”
As NASA pushes the boundaries of human exploration, the successful use of laser communications demonstrated faster data transfer, offering a glimpse into options for future agency missions.
Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery and economic benefits, building the foundation for the first crewed missions to Mars.

Description
NASA’s Curiosity Mars rover used its right navigation camera — one of two on the rover’s mast, or head — to capture the images in this timelapse, which spans six years of driving. The images were snapped between Jan. 2, 2020, and March 8, 2026 (the 2,633rd and 4,830th Martian day, or sol, of the mission, respectively). The images were taken when the mast was looking behind the rover to help the science team choose rocks to study.
Curiosity’s team is using this timelapse to watch for sand grains shifting on the rover’s deck. Distinguishing between sand jostled by each drive and wind gusts can provide new information about seasonal changes in the atmosphere.
Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington as part of NASA’s Mars Exploration Program portfolio.

NASA’s Perseverance, Curiosity Panoramas Capture Two Sides of Mars
NASA’s Curiosity and Perseverance rovers have captured two 360-degree landscapes that highlight how the missions are revealing details of the Red Planet’s formation, watery past, and potential for life. Located 2,345 miles (3,775 kilometers) apart from each other on Mars — about the distance from Los Angeles to Washington, D.C. — both rovers are exploring areas that are billions of years old. But as the nearly 15-year-old Curiosity reaches ever-younger terrain in the foothills of Mount Sharp, the 5-year-old Perseverance is venturing into some of the oldest landscapes in the entire solar system. By time-traveling in opposite directions, the rovers are filling in missing details about the planet’s history.
Stitched together from 1,031 images taken between Nov. 9 and Dec. 7, 2025, Curiosity’s 360-degree panorama offers a detailed look into a region filled with a vast network of boxwork formations: Resembling giant spiderwebs in orbiter images, the low ridges were created by groundwater that once flowed through large fractures in the bedrock. The minerals left behind hardened the rock along the fractures, resulting in erosion-resistant ridges.
Perseverance’s panorama focuses on a place nicknamed “Lac de Charmes,” which sits outside the rim of Jezero Crater. Taken between Dec. 18, 2025, and Jan. 25, 2026, 980 images were stitched together for a 360-degree view capturing the Jezero rim and ancient rocks around the crater.
Driven by CuriosityToday, both of these landscapes are frigid deserts, but evidence of a more dynamic past hides within. When Curiosity landed on the floor of Gale Crater in 2012, it set out to determine whether Mars once had the conditions to support life. Within a year, a sample drilled from an ancient lakebed confirmed those conditions had been present, including the right chemistry and potential nutrients for microbes.
NASA’s Curiosity Mars rover captured this 360-degree view of a region filled with low ridges called boxwork formations between Nov. 9 and Dec. 7, 2025. At 1.5 billion pixels, this is one of the largest panoramas Curiosity has ever taken.Since 2014, Curiosity has been ascending Mount Sharp. Towering 3 miles (5 kilometers) above the crater floor, the mountain first began forming when layers of sediment were deposited in a series of lakes. Long after those lakes dried up, ponds and streams returned several times, leaving a record in the mountain’s layers that formed in drier eras. Because the lowest layers are oldest and higher layers are youngest, Curiosity is essentially progressing back through geological time as it slowly climbs the mountain.
Last year, Curiosity’s team documented how they found that the mineral siderite might be storing carbon dioxide that once was part of a thicker, early atmosphere. Scientists had long suspected that carbonate minerals such as siderite formed when carbon dioxide dissolved into ancient lakes, but such deposits had only rarely been found.
The mission also announced the detection of three of the largest organic molecules ever found on Mars in a sample it had drilled in 2013. The discovery of these long-chain hydrocarbons — possibly the remnants of fatty acids — are a milestone in the search for more complex, prebiotic chemistry on the Red Planet.
And this year, they announced that a rock Curiosity drilled and analyzed in 2020 includes the most diverse collection of organic molecules ever found on the Red Planet. Of the 21 carbon-containing molecules identified in the sample, seven of them were detected for the first time on Mars.
Persevering for sciencePerseverance landed in Mars’ Jezero Crater in 2021 to study the origin of ancient rocks within the crater and to hunt for evidence that microbial life once existed. Billions of years ago, molten rock cooled to form the floor of Jezero Crater. A river then fed a lake in the crater, leaving behind sediments where traces of microbes could have been preserved. In 2024, the mission discovered a rock nicknamed “Cheyava Falls” that was dotted with “leopard spots,” a pattern formed by chemical reactions that microbes are known to create in rocks here on Earth.
NASA’s Perseverance Mars rover captured this 360-degree panorama of a region nicknamed “Crocodile Bridge” on the rim of Jezero Crater. This region holds some of the oldest rocks anywhere in the solar system.NASA/JPL-Caltech/ASU/MSSSWhile Curiosity pulverizes its rock samples for analysis, Perseverance collects samples as intact rock cores, each about the size of a piece of blackboard chalk, and stores them in metal tubes. Aside from a backup set of 10 tubes Perseverance deposited in a sample depot, the rover keeps all its samples (23 so far) on board in its interior. Scientists hope to get these samples into labs on Earth where they can investigate them more fully with instruments far bigger and more complicated than those that can be sent to Mars.
Meanwhile, Perseverance continues to investigate other aspects of the Red Planet. For instance, this past fall, mission scientists shared the first recordings of electrical sparks in passing dust devils — a phenomenon that had only been theorized before Perseverance’s microphones caught them. A separate study detailed how one of Perseverance’s sensitive cameras was able to capture the first visible light auroras from the surface of another planet.
Both missions are looking forward to the next discoveries as they continue to unravel the secrets of Mars. Curiosity has left the boxwork region behind as it continues to explore a mountain layer enriched in salty minerals called sulfates; Perseverance will keep heading toward locations that hold exceptionally old terrain, including one called “Singing Canyon.”
Managed for NASA by Caltech, NASA’s Jet Propulsion Laboratory in Southern California built and manages operations of both Curiosity and Perseverance on behalf of the agency’s Science Mission Directorate as part of NASA’s Mars Exploration Program portfolio.

Volunteers Help NASA Astronauts Record Lunar Flashes
As NASA’s Artemis II astronauts zipped around the Moon in early April, they observed flashes of light caused by meteoroids hitting the lunar surface. At the same time, volunteers for the NASA-funded Impact Flash project scanned the Moon with their own telescopes and sent their videos to scientists to share what they saw from Earth.
“We were incredibly grateful for the videos people submitted,” said Impact Flash project lead Ben Fernando, a planetary scientist at Los Alamos National Laboratory. The locations and brightness of flashes observed by different instruments at different locations together can help constrain the nature and origin of the impactors, as well as the craters they form.
The Artemis II astronauts have splashed back down to Earth, so their observations of the Moon from space have come to a halt for now, but the Impact Flash team is just getting started. They need your continued help scanning the Moon to watch for flashes. If you have access to a telescope four inches in diameter or greater with video capabilities, your observations can make a difference. The more observations you submit, the better the team will be able to constrain the present-day impact rate on the Moon and how it changes over time. Instructions for making and uploading your observations can be found on the Impact Flash website.
In the future, the project team also plans to use your impact flash observations to study tremors on the Moon, similar to earthquakes. They’re called ‘moonquakes’ and they help us figure out what lies beneath the Moon’s surface.
“We are planning to send seismometers to the Moon to measure how the ground shakes,” said Fernando. “Your measurements of impact flashes will help us work out the sources of moonquakes we detect. This will help us work out what the Moon’s interior looks like.”
To collect data during the Artemis II mission, the Impact Flash investigators teamed up with several other groups of amateur astronomers, including the NASA-funded Kilo-nova Catchers, Exoplanet Watch, UNITE (Unistellar Network Investigating TESS Exoplanets), and Night Sky Network teams, as well as the Lunar Impact Flashes project, based at the National Research Council of Italy (IMATI-CNR). Thank you to all those who submitted data.

I Am Artemis: Peter Rossoni
Listen to this audio excerpt from Peter Rossoni, Orion Artemis II Optical Communications System flight manager:
0:00 / 0:00
Your browser does not support the audio element.As a child, Peter Rossoni watched the Apollo missions launch with his family. In April 2026, he became a part of NASA’s Artemis II mission, helping enable communications as astronauts journeyed around the Moon.
Rossoni’s path to NASA began as he followed his parents’ footsteps into science. That foundation eventually led him to laser communications and NASA’s Artemis II test flight.
Peter Rossoni in an optical lab at the Massachusetts Institute of Technology Lincoln Laboratory in Lexington, Massachusetts. MIT-LLToday, Rossoni is the flight manager for the Orion Artemis II Optical Communication System at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Throughout Artemis II, he oversaw the first use of laser communications on a crewed deep space mission.
The optical terminal flew aboard the Orion spacecraft alongside NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen. Through the system, laser communications links transmitted video, photos, engineering, and science data, flight procedures, and crew communications to Earth from the lunar vicinity. In total, the terminal transferred over 450 gigabytes of data to Earth. That’s roughly equivalent to 100 high-definition movies.
The Orion capsule in flight with the O2O payload pointed out. NASADuring the approximately 10-day mission, Rossoni joined the mission control team to ensure smooth data flow from the laser communications terminal on Orion to the Mission Control Center at the agency’s Johnson Space Center in Houston.
“Communications is an important pillar of exploration. We’re venturing into deep space for longer periods of time, and we need that vital link back to the home base. Laser communications were proven to work in previous experiments, so the demonstration phase is over. Artemis II showed us what it can do operationally.”

Flight Manager for the Orion Artemis II Optical Communications System
Laser communications systems use invisible infrared light to pack more data into a single transmission. With downlink speeds of up to 260 megabits per second, the optical communications system was capable of transmitting a full-length 4K movie from the Moon to Earth in about a minute.
“Beyond supporting a crewed mission around the Moon, I’m excited to work with an amazing team of talented engineers and visionaries who understand that high-performance communications and networking is a key element of exploration infrastructure.”
Merging existing infrastructure with the next-generation system was no easy feat. While the system’s laser communications path operated in parallel to traditional radio communications, both tied into the same networks at the Mission Control Center and aboard Orion. The team developed solutions that would allow the systems to work together at the higher rates that laser communications can provide.
To prepare for liftoff, Rossoni and the optical flight and ground teams supported extensive testing activities, including practice runs simulating team and facility operations, the operational readiness reviews confirming the system’s terminal and ground segment, and assuring the teams work smoothly together for the mission. The result was a communications system with up to 100 times greater capacity, enhancing the connection between astronauts and their support teams, while freeing the radio communications systems for sensitive and critical data streams.
“A well-respected scientist at Goddard once said, ‘communications is the secret sauce behind all NASA missions. For Artemis II in particular, with the astronauts’ mission and safety at stake, it was critical to have robust communications to both enhance successful exploration and address any eventualities in the demanding environment of deep space. I had a deep sense of fulfillment when the Orion Artemis II optical communications system started working, and it kept growing as the mission progressed, with more and more objectives achieved.”

The Day of the Trifid Nebula
This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA’s Hubble Space Telescope in an image released on April 20, 2026. The colors in Hubble’s visible light image, which marks the 36th anniversary of the mission’s launch on April 24, are reminiscent of an underwater scene filled with fine-grained sediments fluttering through the ocean’s depths.
Several massive stars, which are outside this field of view, have shaped this region for at least 300,000 years. Their powerful winds continue to blow an enormous bubble, a small portion of which is shown here, that pushes and compresses the cloud’s gas and dust, triggering new waves of star formation.

NASA Celebrates Decade of University Innovation in Aeronautics
8 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater)For 10 years, a NASA initiative has helped the agency produce breakthrough aeronautical innovations while fostering the aviation workforce of tomorrow – and the University Leadership Initiative (ULI) is still flying high, making awards with the potential to change 21st century air travel.
Through ULI, NASA has supported more than 1,100 students at 100 schools, allowing them to pursue advancements in top priority areas for U.S. aviation, including high-speed flight, advanced air mobility, future airspace management and safety, and electrified propulsion.
Many of those students have used their ULI experience as a springboard to careers in aviation. And many of their ideas — such as designing more efficient wings or building supersonic aircraft that can change shape in flight — are either being investigated further by industry or the technologies adopted outright.
As it celebrates a decade of success, NASA’s ULI team is looking forward to leveraging student innovations with new awards in 2026 and beyond.
“Through ULI we’re building the workforce of the future and fostering the skill sets we so desperately need to compete globally,” said John Cavolowsky, director of NASA’s Transformative Aeronautics Concepts Program at NASA Headquarters in Washington.
Through ULI we're building the workforce of the future and fostering the skill set we so desperately need to compete globally.john cavolowsky
Director, Transformative Aeronautics Concepts Program
What makes ULI unique from other NASA research projects, and especially appealing to universities, is that it provides the opportunity for university students and faculty to propose what research to conduct.
Usually, NASA determines the research it needs and then does the work itself or through partnerships and contracts. But with ULI, the agency shares its goals and universities consider how they can best help realize them.
“There are no better ways in my mind to help develop that talent within the students than to engage them in identifying big problems and then give them the resources they need to use their creativity to solve them,” Cavolowsky said.
ULI historyNASA’s relationship with academia and reliance on its research proficiency is written into NASA’s DNA going back to the days of the National Advisory Committee for Aeronautics, from which NASA was formed in 1958.
“For more than a century we have leaned on the brilliance and the capabilities of universities to help us think,” Cavolowsky said. “With ULI we can ensure they continue to bring their fresh ideas and young energy to the work we do at NASA Aeronautics.”
ULI evolved from an earlier project called Leading Edge Aeronautics Research for NASA (LEARN). NASA selected five LEARN teams in 2015 to pursue truly outside of the box ideas that showed promise but needed additional study.
One of those teams, for example, sought to take a cue from migrating flocks of birds by asking if airliners could save fuel by cruising in a giant ‘V’ formation. The numbers were intriguing and simple flight tests proved the concept, although the idea never made it to practice.
Slightly retooled but keeping the innovative spirit of LEARN, ULI was officially announced in 2016 and a year later NASA selected five teams of university professors and students to contribute solutions to the biggest aeronautical challenges of the 21st century.
A decade later, NASA has made a total of $220 million in awards to 33 teams over eight rounds of solicitations
Smooth flyingOne of the earliest selected ULI teams was led by James Coder, who at the time was an aerospace engineering professor at the University of Tennessee in Knoxville. His team worked on technology that would smooth the airflow around a wing to make it more efficient.
Technically known as slotted natural laminar flow (SNLF) wings, Coder has called the idea a potential game changer for commercial airliners. The more efficient wing would mean less drag on an airplane, which in turn could help airlines save money on fuel.
Coder credits ULI for not only helping to prove the technology’s effectiveness – with the aid of wind tunnel testing at NASA’s Ames Research Center in California – but for providing students with an experience they couldn’t get elsewhere.
Three University of Tennessee/Knoxville students and co-investigator Dan Somers (in red jacket) prepare a slotted laminar flow wing section for testing in a wind tunnel at NASA’s Ames Research Center in California.University of Tennessee/Knoxville“After 10 years industry remains interested in the SNLF technology and I am optimistic for good reason about its future,” Coder said. “And project alumni have gone on to do many wonderful things and leverage what they did and learned through the ULI.”
With ULI experience prominent on their resumes, several of the students on Coder’s team wound up with jobs in industry – such as Boeing and Lockheed Martin – and government labs. One is currently a NASA Pathways intern working on his PhD.
Now at Pennsylvania State University, Coder remains a strong advocate for ULI.
“It goes above and beyond simple workforce development,” he said. “We recognized early on the value-add of ULI is the students themselves. While we could have just trained students en masse, we wanted to put them in the front seat of technical leadership on the project. I think this was a very successful strategy that benefited the project and the students as they embarked on their careers.”
Mighty morphingForrest Carpenter is another example of a student whose ULI support led to work after graduation – in this case at NASA.
“Working on the ULI project was an incredible experience, one I will always be thankful for and will remember fondly,” Carpenter said. “I think the project challenged me to be something more than ‘just an engineer;’ really helping my professional development and giving me a clearer focus on my passion.”
As a student at Texas A&M, he was part of a team selected by NASA in 2017 to research a novel idea in which a supersonic aircraft could alter its shape to fly more efficiently based on the atmospheric conditions in real time. Dimitris Lagoudas, now the university’s interim department head for aerospace engineering, led the team.
Members of a University Leadership Initiative round one team led by Texas A&M University participate in a status update meeting with NASA prior to their final review in 2022.Texas A&M University / Jonathan Weaver-RosenA laser shooting out ahead of the aircraft would take measurements of the oncoming air and then the aircraft’s computer would command patches of shape memory alloys and other mechanisms to morph the aircraft’s outer shape.
One possible application of the technology could be in contributing to the reduction of the loudness of a sonic boom, expanding on the science behind NASA’s X-59 quiet supersonic technology demonstrator that seeks to reduce the sonic boom to a sonic thump.
“My main research role on the team was performing Computational Fluid Dynamics simulations of the various geometries we were looking at, including a pre-production version of X-59,” Carpenter said.
His work on the idea continues. A follow-on NASA project, GoSWIFT, will flight test the core technologies Carpenter and his ULI team worked on at Texas A&M. Only this time, Carpenter is the co-lead for the tests, which are targeted to take place at NASA’s Armstrong Flight Research Center in California in the near future.
Carpenter’s enthusiasm for his work and gratitude for how ULI led to his career with NASA resonates with many other ULI alumni.
“The number of students impacted, and how they were impacted, by a long-term project like ULI is huge,” Carpenter said. “NASA’s involvement in this kind of activity can only strengthen the research done in this country and to help inspire and develop the next generation of our workforce.”
ULI is supported by the Transformative Aeronautics Concepts Program within NASA’s Aeronautics Research Mission Directorate, which publishes ULI solicitations and other opportunities to collaborate with the agency’s aeronautical innovators.

Johnson Leaders Honored by National Space Club & Foundation
The National Space Club & Foundation announced its annual award recipients March 13, 2026, in Washington, D.C.
Two dedicated leaders from NASA’s Johnson Space Center were recognized for their contributions to human spaceflight.
Orion Program Manager Howard Hu receives the Norman L. Baker Astronautics Engineer Award. National Space Club & FoundationOrion Program Manager Howard Hu received the Norman L. Baker Astronautics Engineer Award for sustained technical contributions to multiple human spaceflight efforts.
Hu leads the design, development, production, and operations of Orion, NASA’s spacecraft for Artemis missions to the Moon. He has held several leadership roles within the Orion program, including deputy program manager, a manager of the Avionics, Power, and Software Office, and deputy manager of the Vehicle Integration Office. Hu has supported Orion since its inception, beginning as the Vehicle System Performance and Analysis lead.
On April 1, 2026, Artemis II launched on a 10-day voyage around the Moon, marking the first crewed flight of the Orion spacecraft. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen splashed down safely inside Orion April 10 in the Pacific Ocean off the coast of San Diego. At their farthest point, the crew and spacecraft traveled 252,756 miles from Earth, setting a new record for the greatest distance traveled by humans in space.
The mission successfully proved the capability of Orion’s critical systems such as life support with humans aboard. Data from Artemis II will help refine mission operations and further evaluate Orion’s performance in deep space, supporting future Artemis missions.
NASA and its partners are now shifting their focus to Artemis III, which will test integrated operations between Orion and the human landing system in lunar orbit and advance plans to return astronauts to the Moon.
Before joining Orion, Hu served in multiple technical and leadership roles at Johnson, including chief engineer for exploration in the Aeroscience and Flight Mechanics Division, project manager and co-developer of shuttle abort flight management software for the Space Shuttle Cockpit Avionics Upgrades Program, and deputy guidance, navigation, and control system manager for the International Space Station program.
International Space Station Program Manager Dana Weigel receives the Eagle Manned Mission Award. National Space Club & FoundationInternational Space Station Program Manager Dana Weigel received the Eagle Manned Mission Award. She leads development, integration, and operations for the International Space Station. The space station celebrated a historic milestone on Nov. 2, 2025, marking 25 years of continuous human habitation. The orbiting laboratory remains a critical testbed for future commercial destinations in low Earth orbit and for deep space exploration, supporting Artemis missions and future human missions to Mars.
Weigel has held several leadership roles within the program, including deputy chief of the Flight Director Office, where she led the Extravehicular Activity Recovery Team following a major in-flight spacewalk anomaly. She also served as a NASA flight director for STS-123 and led the agency’s geosynchronous Earth orbit satellite servicing habitat study.
