An aircraft powered by a megawatt-class hybrid-electric engine developed in collaboration with NASA and built by GE Aerospace, demonstrated flight of an innovation that can inform new generations of fuel-saving aircraft power systems.

Mounted to a Saab 340B aircraft, the engine flew at Farnborough International Air Show in the United Kingdom. It was the public debut of a system that has in recent months made historic test flights, becoming the first hybrid electric-powered aircraft to fly above 30,000 feet.

“This achievement reflects what NASA does best in aeronautics: we explore bold possibilities, validate them through rigorous research and testing, and work with industry to turn breakthrough ideas into technologies that bring real value for the American people,” said Laurie Grindle, director of the Aeronautics Division within the agency’s Research and Technology Mission Directorate at NASA Headquarters in Washington.

The testing leveraged work done through NASA’s former Electrified Powertrain Flight Demonstration project and the agency’s ongoing Subsonic Vehicle Technologies and Tools project – years of collaborative research that included key testing at NASA test facilities. 

The engine integrates electric motors, a gas turbine, and energy storage capabilities. It was designed to demonstrate the capacity to power an aircraft around the size of a regional-class jet, reducing fuel burn and costs without sacrificing performance. The unit’s technology and designs are expected to be used to help develop future hybrid systems that could lower airline operating costs. 

The demonstration flight came after years of rapid development for the technology. For NASA, it also validates work that stretches back to a time when hybrid aviation propulsion seemed almost beyond the horizon of possibility.

“This is the culmination of more than 15 years of work, and we did that because it’s going to have an impact for aircraft that will help reduce energy use and help U.S. companies and the public,” said Ralph Jansen, aerospace engineer at NASA’s Glenn Research Center in Cleveland. “It’s about having a vision that no one believes can happen and then doing the work to define and execute the research and development needed to make it happen.”  

This accomplishment was possible because of the collaborative effort of hundreds of people working on Electrified Powertrain Flight Demonstration and Subsonic Vehicle Technologies and Tools projects across NASA centers, in conjunction with GE Aerospace and its partner companies.

Hybird-Electric Evolves

In recent years, aviation has seen a boom in small aircraft and drones powered by electrical systems drawing from batteries. But large passenger and cargo planes require complex engines capable of supplying massive amounts of power. So more than a decade ago when NASA began contemplating hybrid systems, just the possibility of using electric motors to supplement some energy was a daunting engineering challenge. 

NASA spent about seven years performing preliminary research, working with small businesses and other partners to consider technological obstacles and the potential commercial viability of hybrid systems. During that time, the agency addressed several barriers to implementation including the power, thermal, and battery technology, and the integration of the power system, engine, and aircraft.

Through the agency’s Electrified Powertrain Flight Demonstration award, GE Aerospace and NASA worked with researchers to develop lighter and more efficient power systems and shrink key components – sometimes dramatically. 

NASA and GE Aerospace also leveraged agency facilities and resources to further their research. In 2022, GE Aerospace tested an integrated version of its propulsion system at NASA’s Electric Aircraft Testbed at the agency’s Neil A. Armstrong Test Facility in Sandusky, Ohio. Testing allowed the system to operate in conditions simulating 45,000 feet in altitude, the range in which commercial single-aisle aircraft fly. 

The team added components, including electric motors, power converters, propellers, and a GE Aerospace commercial engine, followed by more ground tests and eventual flight tests. For the researchers who’d spent years on the concept, seeing the engine powering an aircraft in flight was a major step in a long journey.

“I’ve got to say, I was pretty touched seeing it fly. It was just awesome,” Jansen said.  “It’s just like a regular plane, which is probably the best thing of all.”

NASA’s current support for this research is through the Aeronautics Division of its Research and Technology Mission Directorate.

Testing new aerospace concepts in flight remains one of NASA’s most effective ways to advance knowledge and reduce risk.

The Dale Reed Subscale Flight Research Laboratory at NASA’s Armstrong Flight Research Center in Edwards, California, supports this mission by using small, remotely piloted and autonomous aircraft as cost‑effective platforms to mature innovative ideas, accelerate learning, and enable smoother transitions to full‑scale flight.

When experiments require a flight platform, several NASA remotely piloted aircraft are available: the Alta‑X quadrotor; the Dryden Remotely Operated Integrated Drone (DROID) with its 10‑foot wingspan; and the Multi‑Use Cub, a 14‑foot‑span fixed‑wing aircraft with an expandable payload capacity for flight experiments. For electric vertical takeoff and landing testing, the HQ‑90 quadrotor provides an additional option.

Once aircraft and experiments are cleared for operations, laboratory pilots support the mission, including ground operations and flight activities.

Flight expertise

Each staff member serves as an experienced and certified subscale aircraft pilot and is prepared to fly unique one-of-a-kind or modified commercial aircraft wherever the mission requires.

NASA’s FireSense project conducted flights in the Geneva State Forest, located about 100 miles south of Montgomery, Alabama. NASA Armstrong flight research staff integrated the instrument onto an Alta-X drone and tested the system before deployment. Two team members then transported the drone and sensor to the forest, prepared the vehicle for flight, and operated it during the mission. The NASA sensor was flown on the drone to demonstrate how remotely piloted aircraft can gather localized weather data that influences smoke movement and fire behavior. This information may help operational agencies improve wildfire decision-making and better allocate firefighters and resources.

Other missions occur closer to NASA Armstrong, such as the Enhancing Parachutes by Instrumenting the Canopy (EPIC) project. EPIC involved air‑launching a capsule containing a parachute and flexible sensor from the Alta‑X. Laboratory staff piloted the flights, supported flight operations, and worked with the EPIC team to design and integrate the parachute‑drop mechanism and safety system into the aircraft.

These tests demonstrated that a flexible sensor could help researchers study supersonic parachutes. Continuation of this work can help fill gaps in computer models, making supersonic parachutes safer and more reliable for delivering science instruments and payloads to Mars.

Advancing challenging research

The Dale Reed Subscale Flight Research Laboratory uses rapid design and testing capabilities to help small aircraft fly big ideas. These concepts could lead to future breakthroughs that support NASA’s missions across aeronautics, science, and exploration.

For decades, NASA and its partners have advanced Automatic Collision Avoidance Technology. The research demonstrated an autopilot could detect and recover from an imminent ground collision – a capability now helping save lives in high‑performance U.S. military jets. NASA Armstrong had key roles in that work and developed a simplified version, the Automatic Ground Collision Avoidance System, which was installed on the DROID for testing.

The system demonstrated on the DROID — developed to assist general aviation pilots as well as remotely piloted and autonomous aircraft — performed well and led to further research toward a version that provides alerts and steering cues. The NASA Armstrong Technology Transfer Office is working to license the technology for U.S. businesses to develop the system as a commercial product.

The Prandtl‑D (Preliminary Research Aerodynamic Design to Lower Drag) flying‑wing glider was also designed, fabricated, and flown at NASA Armstrong. Researchers found that its twisted wing design could reduce drag and generate thrust at the wingtips, advancing concepts that may support greater fuel economy for future aircraft. The original Prandtl‑D is now part of the Smithsonian National Air and Space Museum collection in Washington, and the Prandtl-D3 is at the California Science Center in Los Angeles. Researchers continue developing the next generation of the design in the laboratory.

A wide range of capabilities in the laboratory help transform promising concepts into flight-ready test structures. These include rapid prototyping using traditional and advanced 3D manufacturing techniques, as well as composite and conventional fabrication processes. The team of engineers and technicians also provides custom component design and specialized fabrication to meet unique research needs.

The laboratory supports electrical and mechanical design, hardware and software integration, and the safety and flight-readiness processes required for successful missions. Additional technical facilities, such as the Experimental Fabrication Branch and the Environmental Laboratory at NASA Armstrong, further enhance these capabilities. Together, they support development, testing, and validation activities that advance NASA’s aeronautics and exploration goals.

NASA Pushes New Wing Design to Find Structural Limits

A wide view of a test structure in a laboratory shows a full test assembly secured inside a steel rig. Hydraulic lines, sensors, and support equipment surround the structure, with additional lab equipment visible in the background.

The 15-foot Structural Wing Experiment Evaluating Truss-bracing test article is fully installed in the Flight Loads Laboratory at NASA’s Armstrong Flight Research Center in Edwards, California, on Wednesday, May 20, 2026. The model is part of NASA’s research to develop technologies for future ultra-efficient aircraft.

NASA researchers recently put a new wing design, appearing long and thin with a lightweight structural design, through a series of grueling tests to find its structural limits. What they found left them encouraged about the wing’s potential, even when they pushed it past its intended limits.

The 15-foot Structural Wing Experiment Evaluating Truss-bracing (SWEET-15) test article is part of NASA’s research to develop future ultra-efficient aircraft. The design incorporates a long wing supported by an aerodynamic strut, based on NASA’s earlier Transonic Truss‑Braced Wing concept.

The research team is working to understand whether SWEET-15’s design and its new lightweight structural designs could help commercial airliners save fuel. But first, they need to understand how it behaves under the kinds of force wings experience in flight.

A group of people work together in a large workshop, handling and inspecting a long metallic structure laid across padded tables. Tools, materials, and protective equipment are spread across the workspace.
Lab technicians Phil Tofts, Chris McLain, and Jeff Howell and NASA engineers Erin Anderson and Richard Larson prepare the 15-foot Structural Wing Experiment Evaluating Truss-bracing model in the Flight Loads Laboratory at NASA’s Armstrong Flight Research Center in Edwards, California, on Thursday, Dec. 11, 2025. The model is part of NASA’s research to develop technologies for future ultra-efficient aircraft. 
NASA/Christopher LC Clark

The SWEET-15 design originated with combining five different advanced composite manufacturing and assembly technologies that enabled the novel structural design. The 15-foot-long test article was then designed and fabricated at NASA’s Langley Research Center in Hampton, Virginia, before traveling to NASA’s Armstrong Flight Research Center in Edwards, California, for testing.

Over several months, NASA engineers intentionally bent the test wing in the Flight Loads Laboratory at NASA Armstrong. Numerous strain and load sensors, including fiber-optic strain sensors, were placed throughout the structure to track how the wing responded as forces increased.

The data from the sensors confirmed the predictions made by NASA’s computer models. According to initial findings, the wing withstood the anticipated in-flight forces without issue. The results provided the team with confidence in the new manufacturing approaches and methods for connecting wing parts used in SWEET-15, which could support future efficient aircraft designs. The manufacturing approach, developed at NASA Langley used the Integrated Structural Assembly of Advanced Composites robot, aims to produce lighter and stronger composite structures for aerospace vehicles.

NASA/Christopher LC Clark

The test concluded with a deliberate test-to-failure, where engineers increased loads beyond the wing’s design limits to determine how and where it would fail. The structure ultimately failed at roughly 127% of its design limit load, with visible damage appearing near the back edge of the wing and in the upper wing cover. This element of testing provided valuable insight into how the joints connecting the wing to its main strut and a secondary one, called a jury strut, behave under forces beyond the expected flight envelope.

This marks the first time a representative composite truss-braced wing configuration has undergone this type of structural evaluation.  It was made possible only through NASA collaboration across centers and projects, with researchers utilizing agency resources such as the Fiber Optic Sensing System developed to gather data on both aircraft and spacecraft.

A man wearing ear protection works closely with multiple hydraulic and instrumentation units connected to a large beam mounted on a test structure. Numerous cables, hoses, and measurement devices extend from the setup.

To prepare for the testing, engineers at NASA Langley designed, analyzed, and manufactured the wing and completed safety preparations and lab setup.

Researchers will now analyze the data collected during testing to inform future airframe designs and support NASA’s ongoing efforts to develop more efficient aviation technologies.

The work is being conducted through NASA’s Subsonic Flight Demonstrator project in the agency’s Research Technology Mission Directorate. The successful testing of multiple innovative components marks a milestone in NASA’s aeronautics research.

Description

Five antennas soak in the summer sun at the Deep Space Network’s Goldstone complex near Barstow, California, in August 2026. The recently completed Deep Space Station 23, a 34-meter (114-foot) beam-waveguide antenna, can be seen to the right of the frame in the foreground. The other three 34-meter antennas are, from left, DSS-26, DSS-25, and DSS-24. At farthest right is a smaller 26-meter (85-foot) antenna, the retired “Apollo Antenna” that was built in 1967 as part of the Manned Space Flight Network and earned its nickname for providing tracking for the Apollo Program.

NASA leadership and personnel as well as dignitaries gathered at the complete DSS-23 antenna for a ceremonial ribbon-cutting on Aug. 25, 2026. It’s the latest antenna to be added as part of the Deep Space Network’s Aperture Enhancement Project, which began in 2009 to upgrade and expand the network by adding six new 34-meter multifrequency beam-waveguide antennas. These versatile Deep Space Network (DSN) dishes can enhance many missions operating over different radio frequencies. 

The DSN allows missions to track, send commands to, and receive scientific data from faraway spacecraft. It is managed by NASA’s Jet Propulsion Laboratory in Southern California, a division of Caltech, for the agency’s Space Communications and Navigation (SCaN) Program, which is located at NASA Headquarters within the Research and Technology Mission Directorate.

New Next-Gen Dish Adds Muscle to NASA’s Deep Space Network

NASA’s Deep Space Network facility in California is marking the addition of a brand new 34-meter-wide (114-foot-wide) radio frequency antenna to the agency’s deep space communications and navigation system. The network uses giant dish antennas located at three global facilities to support more than 40 spacecraft exploring the solar system and interstellar space.

The new Deep Space Station 23 (DSS-23) is located at the Goldstone Deep Space Communications Complex, near Barstow, and is managed by NASA’s Jet Propulsion Laboratory in Southern California.

NASA leadership and personnel as well as dignitaries gathered at the complete DSS-23 antenna for a ceremonial ribbon cutting. It’s the latest to be added as part of the Deep Space Network’s Aperture Enhancement Project, which began in 2009 to upgrade and expand the network by adding six new 34-meter multifrequency beam-waveguide antennas. These versatile dishes can enhance many missions operating over different radio frequencies.

“By expanding the Deep Space Network, we are strengthening the communications foundation NASA needs for the bold missions ahead — from exploring more of the Moon than ever before to peering deeper into the solar system,” said James Kenyon, associate administrator of the Research and Technology Mission Directorate at NASA Headquarters in Washington. “This new antenna will help us deliver on our national goals for space exploration and push beyond the limits of what once seemed impossible.”

After completing a testing campaign from May through July to demonstrate its capabilities, the new DSS-23 began operations on Aug. 3, tracking NASA’s Chandra X-ray Observatory. Since then, it has been communicating with dozens of missions such as NASA’s Mars Reconnaissance Orbiter, Psyche, Juno, Voyager 1, and other robotic spacecraft in deep space.

“The addition of this next-generation antenna brings us closer to a completely modernized network that embraces advanced technology to ensure NASA’s leadership in deep space communications,” said Dave Gallagher, director of JPL. “After over 60 years of continuous operations supporting consequential missions, these upgrades prime the network for a new era of exploration. The teams that designed, planned, and built DSS-23 should be proud.”

Enhanced capabilities

Construction of DSS-23 began in February 2020. After the 133-ton metal reflector framework was placed and bolted atop the antenna’s pedestal in December 2024, engineers installed the panels to the framework that reflect radio frequency signals transmitted to and received from spacecraft. Then came the careful process of calibrating the antenna so it can work in concert with the rest of the network.

It is the fifth antenna at Goldstone (joining three 34-meter antennas and one 70-meter, or 230-foot, antenna) and the fifth enhancement project antenna to join the network, which includes antennas at the DSN’s Goldstone, Madrid, and Canberra, Australia, complexes. Multifrequency beam waveguide antennas direct signals down to a stable, climate-controlled underground room, rather than housing heavy, sensitive electronic equipment on the moving antenna dish. In addition to offering versatility, this design allows easy access for maintenance and upgrades to the system.

“The biggest challenge wasn’t actually constructing the antenna. It was transforming a complex collection of mechanical, electrical, software, radio frequency, and infrastructure systems into a single, mission-ready asset,” said Germaine Aziz, manager of the Deep Space Network Aperture Enhancement Project at JPL. “Every subsystem must be integrated, calibrated, and verified to operate with extraordinary precision and reliability before it can support NASA’s deep space missions.”

The enhancement project will be complete when a sixth enhancement-project antenna, Deep Space Station 33, comes online at the Canberra facility in 2029, bringing the total number of 34-meter antennas across the network to 13. The 34-meter antennas can be arrayed (combined and operated together) to provide an equivalent communications backup for each facility’s single 70-meter antenna, which, after more than 50 years of near-continuous operation, are getting increasingly costly to maintain and repair.

Managed by Caltech for NASA, JPL manages the agency’s Deep Space Network with the oversight of NASA’s SCaN (Space Communications and Navigation) Program within NASA’s Research and Technology Mission Directorate. More than 100 NASA and non-NASA missions rely on the Deep Space Network and Near Space Network. They include missions that support astronauts aboard the International Space Station and future Artemis missions, monitoring Earth, exploring the Moon, and exploring the solar system and beyond.

Development

The Copernicus Project started at the University of Texas at Austin in August 2001. In June 2002, a grant from the NASA Johnson Space Center (JSC) was used to develop the first prototype which was completed in August 2004. In the interim, support was also received from NASA’s In Space Propulsion Program and from the Flight Dynamics Vehicle Branch of Goddard Spaceflight Center. The first operational version was completed in March 2006 (v1.0). The initial development team consisted of Dr. Cesar Ocampo and graduate students at the University of Texas at Austin Department of Aerospace Engineering and Engineering Mechanics. Since March 2007, primary development of Copernicus has been at the Flight Mechanics and Trajectory Design Branch of JSC.

Lala skirts south of the Island of Hawaiʻi as a category 1 hurricane in the right image, acquired by the VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite on August 15, 2026, at about 1:45 p.m. Hawaii Standard Time (23:45 Universal Time). The storm decreased in intensity while tracking northwest and was a tropical storm when the VIIRS on the NOAA-20 satellite captured the left image about 24 hours later. NASA Earth Observatory images by Lauren Dauphin.

The Island of Hawaiʻi narrowly avoided a direct landfall by Hurricane Lala in mid-August 2026. The storm nonetheless delivered serious damage as it passed just south of the island on August 15 (above, right) as a category 1 storm on the Saffir-Simpson wind scale.

Lala brought rainfall totals exceeding 20 inches (50 centimeters) to parts of the island, causing flash flooding and ongoing mudflow risks. The highest rainfall total for the storm—43.55 inches (110.6 centimeters) as of the morning of August 17—was recorded at Laupāhoehoe, on the coast northwest of Hilo. Lala downed trees, damaged bridges, and knocked homes off their foundations. Coastal areas were pummeled by large waves, while the summit of Mauna Kea, over 13,000 feet (4,000 meters) above sea level, experienced blizzard conditions.

By early afternoon on August 16, when the other image (left) was acquired, the storm had tracked northwest, roughly parallel to the island chain, and was southwest of Kauaʻi. Lala had decreased in intensity to a tropical storm, with sustained winds of 65 miles (105 kilometers) per hour, according to the National Hurricane Center.

While the Island of Hawaiʻi took the brunt of the storm, other islands also saw destructive effects. Strong winds caused widespread power outages, with more than 220,000 customers statewide without power as of the afternoon of August 16, according to news reports. Across the islands, wind and rain damaged infrastructure, and floodwaters and debris rendered roads impassable.

It has been an active tropical cyclone season in the Eastern Pacific so far in 2026, meteorologists note, consistent with what scientists expect during an El Niño, which has been underway as of mid-June. Warm water in the equatorial Pacific—the hallmark of El Niño—and the moisture and energy it transfers to the atmosphere help fuel nascent tropical storms. Lack of wind shear, another typical El Niño pattern in this region, also encourages tropical storms to develop and strengthen. The Atlantic hurricane season, in contrast, has been relatively calm, as greater wind shear over the Atlantic Ocean and Caribbean Sea during an El Niño inhibits hurricane formation by dissipating the upward motion of heat.

A smoke-infused pyrocumulonimbus (pyroCb) rises from the Widemouth 2 fire in Utah in these images captured by the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Aqua satellite. The left image is natural color; the right image is false color, revealing cloud-top brightness temperatures below -40°C, a commonly used threshold for identifying pyroCbs. NASA Earth Observatory images by Michala Garrison.

Scientists have long known that volcanoes can launch large quantities of particles into the stratosphere. In the past few decades, it has become clear that wildfires do this, too, by generating towering, smoke-infused pyrocumulonimbus (pyroCb) clouds.

The largest pyroCbs are stunning weather-making features that generate massive thunderheads capable of unleashing lightning, hail, and heavy rain. A growing body of research shows that pyroCbs can also leave an outsized imprint on the upper atmosphere by channeling pulses of particles and gases into the stratosphere’s mostly dry, cloudless confines. Once there, smoke can spread widely and linger for months or years, sometimes circling the globe and likely influencing the ozone layer and Earth’s energy budget.

Understanding these enigmatic and dangerous clouds is why a team of atmospheric scientists—part of a NASA mission called INSPYRE (INjected Smoke and PYRocumulonimbus Experiment)—is spending the summer chasing them with NASA’s ER-2 aircraft, NSF/NCAR’s GV, and a suite of truck-based sensors. The team completed one of its first sampling runs of the summer on August 3, 2026, when the GV flew through a high-altitude pulse of smoke from the Widemouth 2 fire, one of Utah’s largest so far this year.

Lightning ignited the fire on July 27, 2026, but it remained relatively small until August 2, when it more than doubled in size amid intense winds and hot, dry conditions. That afternoon, soon after it had produced two pyroCb bursts, the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Aqua satellite captured this image (above), showing a chimney of high-altitude cloud and smoke casting a shadow on low-altitude smoke below.

These bursts propelled clouds high enough that Aqua measured cloud-top brightness temperatures well below −40°C, a common threshold for identifying pyroCbs and a sign that the cloud tops were bubbling to the top of the troposphere and sometimes into the stratosphere. The brightness temperature measurements “reveal two discrete pulses of pyroCb action,” said Michael Fromm, a scientist at the U.S. Naval Research Laboratory. “The westernmost is the youngest pulse and stands out in the visible imagery by virtue of its shadow.”

Though relatively routine and minor, this pyroCb event followed a pre-dawn pyroCb from the same fire, imaged by the NOAA weather satellite GOES-West. “Morning pyroCbs are much more unusual,” Fromm said, because they don’t benefit from daytime heating that helps fuel convection. In this case, however, there appeared to be enough atmospheric instability and water vapor in the air to allow for pyroCb development. 

Multiple pyroCbs in a single day could have added unwanted complexity for forecasters and fire officials battling the blaze and organizing evacuations, said David Peterson, INSPYRE’s principal investigator. “Minimizing that sort of uncertainty for fire forecasters is a big part of the reason we’re out here studying this,” he added.

Remote sensing experts like Peterson and Fromm routinely study pyroCbs from afar with satellites, but it’s less common for pilots to chase and sample smoke plumes just hours after they form. In this case, the GV aircraft, on the ground in Colorado when the Widemouth 2 fire blew up, made a beeline for a high-altitude smoke plume as it drifted over New Mexico on August 3. The instruments on the plane sampled smoke at roughly 12 kilometers (8 miles) above the surface, collecting data at a height that isn’t typically incorporated into forecast models.

An aerial image shows a thick, puffy white cloud rising high above a patch of darker smoke visible near a surface of variable mountainous terrain.

During that mission, a scientist on board captured this image (above) of a pyrocumulus (pyroCu) billowing up over the Widemouth 2 fire. While not as tall or energetic as pyroCbs, pyroCus are precursor clouds that share many of the same characteristics. Here, heat from the fire is fueling strong convective updrafts, forming a towering cloud with puffy overshooting tops that poke into the upper troposphere as lower-altitude smoke drifts below.

Satellites excel at identifying pyroCbs by measuring the temperature of the cloud tops that form above smoke plumes. Using this technique, researchers have established that wildfires produce about 70 pyroCbs per year, many in dense forests of Canada and Russia, though plenty also occur in grasslands and savannas in the United States and Australia. So far in 2026, Fromm and colleagues have identified at least 13 in the continental United States.

Since one of the first pyroCbs appeared in the scientific literature in the early 2000s, scientists have cataloged well over 700 events, and they now believe that wildfires may contribute up to 25 percent of the black carbon and organic aerosols in the lower stratosphere. The sheer frequency of pyroCbs means that the total mass of particles they inject over the course of a wildfire season may rival that of large volcanic eruptions.

Still, many questions about the enigmatic clouds remain unanswered. It isn’t clear what vegetation is most likely to fuel pyroCbs, why some form more lightning than others, why they form in only a small fraction of fires, and how to accurately forecast them.

“Whether it be their dangerous manifestations on the ground or their long-lasting imprint on the upper troposphere and lower stratosphere,” Fromm said, “pyroCbs continue to surprise us.”

The barren lunar landscape has some important resources, such as water and minerals like iron and titanium, but extracting and processing them will require special equipment. Where those resources can be found will dictate where to land and how to mine them. To help with that, Lunar Station Corp. is using a wealth of NASA data in multiple computer models.

“With 60 years of lunar data available to us, we help our clients understand the environmental factors for any given location on the Moon,” said Blair DeWitt, CEO of Lunar Station. Combining disparate data from different sensors used by NASA and other space agencies is a critical first step. One NASA resource the Cambridge, Massachusetts-based company used to build terrain maps is the Ames Stereo Pipeline. The open-source code automatically processes images captured from satellites, robotic rovers, historical images, and more to create a 3D model revealing features such as rock placement and elevation.

But the availability of in-situ lunar water resources at any location is largely unknown, according to Gerry Sanders, in-situ resource utilization system capability lead at NASA’s Johnson Space Center in Houston. To begin to fill that gap, the Lunar Crater Observation and Sensing Satellite was designed to crash its uppers stage into the Moon’s South Pole in 2009. The examination of the resulting plume revealed the presence of water ice.

Lunar Station is building on that work and more to help commercial space companies with mission planning, which includes scientific research for mining operations. The MoonHacker program uses proprietary geospatial analytics platform and advanced algorithms to fuse all the lunar data in NASA’s Planetary Data System to help identify indicators for shallow pits of lunar water.

“We can find sites for landing pads, for cultivating the best paths for roving, and inform our clients about communications. If you can’t see Earth at a given location like in the polar regions or the far side of the Moon, you have to come up with a relay strategy,” said DeWitt. “We can do this in part thanks to NASA data.”

In MoonHacker’s Radiation Simulator, an electronic version of a company’s rover or satellite, called a digital twin, can be subjected to the radiation en route or at the mission site to determine the protection required.

These innovations exemplify the purpose of NASA’s Technology Transfer program within the Research and Technology Mission Directorate, which uses space-based solutions to improve life on Earth. For 50 years, NASA has documented the everyday benefits of space technology through the agency’s Spinoff publication.

NASA Delivers Navigation System for Commercial Lunar Relay

The Moon's rugged surface is on display in this image. Most of the Moon is visible, with the bottom of the sphere disappearing into the darkness. This line between light and dark is called the terminator. The terminator is lined with many craters.

The Moon’s rocky, uneven, and otherworldly surface features are highlighted by the terminator – the difference between light and darkness.

NASA delivered the NavCube3-mini payload on July 13 to Intuitive Machines for integration into Altus-1, the company’s first lunar relay satellite, marking an important milestone in the development of future lunar communications and navigation services. The lunar relays are designed to enable communications and navigation for astronauts and rovers operating at the agency’s future Moon Base.

About half the size of a shoebox and weighing just 3.5 pounds, NavCube3-mini is a compact but powerful navigation receiver designed to use signals from Earth-based GPS and Galileo Global Navigation Satellite Systems (GNSS) at lunar distances. Operating on less than 20 watts of power, roughly the same as a laptop computer, it can determine a spacecraft’s precise position far beyond Earth orbit. The compact payload builds on a series of navigation technology advancements developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, each extending GPS navigation to new record-breaking distances from Earth.

The payload will fly aboard Intuitive Machines’ Altus-1 lunar relay satellite, the first of a planned network of lunar relay satellites being developed under the company’s Near Space Network Services contract with NASA. The relays will provide communications and navigation support for missions operating at the Moon, including the challenging lunar South Pole region, where Artemis astronauts will land in 2028, and where direct communications with Earth can be difficult. By extending communications coverage and improving navigation services, the relay network will help realize NASA’s vision for a sustained human presence on the lunar surface.

Before being shipped to Intuitive Machines, NavCube3-mini underwent an extensive environmental and performance test campaign at NASA Goddard to verify it is ready for spaceflight. The environmental testing included vibration testing to simulate launch conditions, thermal vacuum testing in the extreme temperatures and vacuum of space, and electromagnetic compatibility testing to ensure the payload can operate reliably alongside other spacecraft systems without causing or experiencing electromagnetic interference. Performance testing was conducted before and after each environmental test using high-fidelity simulations of the GPS and Galileo signals the NavCube will encounter in lunar orbit, verifying functionality and performance throughout the testing campaign.

NavCube3-mini will serve as a key technology demonstration aboard Altus-1, validating the use of GNSS-based navigation in the lunar region and providing valuable performance data to support the development of future lunar navigation infrastructure. This technology is part of NASA’s broader strategy to develop communications and navigation services that work across both commercial providers and NASA’s networks. These capabilities are designed to support a growing lunar ecosystem that includes orbiters, landers, rovers, and, eventually, astronauts living and working on the Moon.

The delivery of NavCube3-mini marks another step toward building the communications and navigation infrastructure needed for long-term lunar exploration. Through partnerships with commercial providers like Intuitive Machines, NASA is building a more connected and capable lunar environment. As activity around the Moon continues to grow, these capabilities will enable lunar spacecraft and explorers to operate more safely, efficiently, and autonomously.
