Two NASA-developed technologies are key components of a new high-resolution sensor for observing wildfires: High Operating Temperature Barrier Infrared Detector (HOT-BIRD), developed with support from NASA’s Earth Science Technology Office (ESTO), and a cutting-edge Digital Readout Integrated Circuit (DROIC), developed with funding from NASA’s Small Business Innovation Research (SBIR) program.
NASA’s c-FIRST instrument could provide high resolution data from a compact space-based platform in under an hour, making it easier for wildfire managers to detect and monitor active burns. Credit: NASA/JPL A novel space-based sensor for observing wildfires could allow first responders to monitor burns at a global scale, paving the way for future small satellite (SmallSat) constellations dedicated entirely to fire management and prevention.
Developed with support from NASA’s Earth Science Technology Office (ESTO), the “Compact Fire Infrared Radiance Spectral Tracker” (c-FIRST) is a small, mid-wave infrared sensor that collects thermal radiation data across five spectral bands. Most traditional space-based sensors dedicated to observing fires have long revisit times, observing a scene just once over days or even weeks. The compact c-FIRST sensor could be employed in a SmallSat constellation that could observe a scene multiple times a day, providing first responders data with high spatial resolution in under an hour.
In addition, c-FIRST’s dynamic spectral range covers the entire temperature profile of terrestrial wild fires, making it easier for first-responders to detect everything from smoldering, low-intensity fires to flaming, high intensity fires.
“Wildfires are becoming more frequent, and not only in California. It’s a worldwide problem, and it generates tons of by-products that create very unhealthy conditions for humans,” said Sarath Gunapala, who is an Engineering Fellow at NASA’s Jet Propulsion Laboratory (JPL) and serves as Principal Investigator for c-FIRST.
The need for space-based assets dedicated to wildfire management is severe. During the Palisade and Eaton Fires earlier this year, strong winds kept critical observation aircraft from taking to the skies, making it difficult for firefighters to monitor and track massive burns.
Space-based sensors with high revisit rates and high spatial resolution would give firefighters and first responders a constant source of eye-in-the-sky data.
“Ground-based assets don’t have far-away vision. They can only see a local area. And airborne assets, they can’t fly all the time. A small constellation of CubeSats could give you that constant coverage,” said Gunapala.
c-FIRST leverages decades of sensor development at JPL to achieve its compact size and high performance. In particular, the quarter-sized High Operating Temperature Barrier Infrared Detector (HOT-BIRD), a compact infrared detector also developed at JPL with ESTO support, keeps c-FIRST small, eliminating the need for bulky cryocooler subsystems that add mass to traditional infrared sensors.
With HOT-BIRD alone, c-FIRST could gather high-resolution images and quantitative retrievals of targets between 300°K (about 80°F) to 1000°K (about 1300°F). But when paired with a state-of-the-art Digital Readout Integrated Circuit (DROIC), c-FIRST can observe targets greater than 1600°K (about 2400°F).
Developed by Copious Imaging LLC. and JPL with funding from NASA’s Small Business Innovation Research (SBIR) program, this DROIC features an in-pixel digital counter to reduce saturation, allowing c-FIRST to capture reliable infrared data across a broader spectral range.
Artifical intelligence (AI) will also play a role in c-FIRST’s success. Gunapala plans to leverage AI in an onboard smart controller that parses collected data for evidence of hot spots or active burns. This data will be prioritized for downlinking, keeping first responders one step ahead of potential wildfires.
“We wanted it to be simple, small, low cost, low power, low weight, and low volume, so that it’s ideal for a small satellite constellation,” said Gunapala.
Gunapala and his team had a unique opportunity to test c-FIRST after the Palisade and Eaton Fires in California. Flying their instrument aboard NASA’s B-200 Super King Air, the scientists identified lingering hot spots in the Palisades and Eaton Canyon area five days after the initial burn had been contained.
Now, the team is eyeing a path to low Earth orbit. Gunapala explained that their current prototype employs a standard desktop computer that isn’t suited for the rigors of space, and they’re working to incorporate a radiation-tolerant computer into their instrument design.
But this successful test over Los Angeles demonstrates c-FIRST is fit for fire detection and science applications. As wildfires become increasingly common and more destructive, Gunapala hopes that this tool will help first responders combat nascent wildfires before they become catastrophes.
“To fight these things, you need to detect them when they’re very small,” said Gunapala.
A publication about c-FIRST appeared in the journal “Society of Photo-Optical Instrumentation Engineers” (SPIE) in March, 2023.

Video: 00:02:27 2025 marks a landmark year for Europe’s ‘bridge between Earth and space’. The European Space Agency’s Estrack satellite tracking network turns 50.
Since its inception in 1975, Estrack – ESA’s global network of ground stations – has formed the vital communication bridge between satellites in orbit and mission control at the European Space Operations Centre (ESOC) in Darmstadt, Germany.
Now comprising six stations spanning six countries, Estrack has grown into a strategic asset for Europe, enabling communication with spacecraft, transmitting commands and receiving scientific data.
The network keeps an eye on satellites no matter their location: tracking them across Earth orbit, voyaging to comets or asteroids, keeping station at the scientifically important Sun-Earth Lagrange points, and deep into our Solar System. It even keeps tabs on European launchers as they soar into orbit, ensuring no rocket is ever out of reach.
Fittingly, this celebration of technological excellence coincides with the 200th birthday of Johann Strauss II and the 50th anniversary of ESA. To honour this convergence of milestones, ESA and the Vienna Tourist Board are orchestrating a unique mission: broadcasting The Blue Danube Waltz to its destined home among the stars.
Don’t miss the live concert of the Wiener Symphoniker (Vienna Symphony Orchestra) on Saturday, 31 May. The event will start at 20:30 CEST and the transmission from ESA’s Cebreros antenna will occur at 21:30 CEST.
The live stream can be followed via space.wien.info and the Vienna Instagram channel.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Boeing’s test plane simulates digital taxiing at Moffett Field at NASA’s Ames Research Center in California’s Silicon Valley. NASA/Brandon Torres Navarrete New technology tested by an industry partner at NASA’s Ames Research Center in California’s Silicon Valley could improve how commercial planes taxi to and from gates to runways, making operations safer and more efficient on the surfaces of airports.
Airport taxiways are busy. Planes come and go while support vehicles provide maintenance, carry fuel, transport luggage, and more. Pilots must listen carefully to air traffic control when getting directions to the runway – and garbled communications and heavy workloads can cause issues that could lead to runway incursions or collisions.
Researchers at Boeing are working to address these issues by digitizing taxiway information and automating aircraft taxi functions. The team traveled to NASA Ames to collaborate with researchers while testing their technology at the Moffett Federal Airfield and NASA’s FutureFlight Central, an air traffic control simulation facility.
Doug Christensen, test engineer for Air Traffic Management eXploration (ATM-X) at NASA Ames, and Mike Klein, autonomy technical leader in product development at Boeing discuss the digital taxi test in Ames’s FutureFlight Central facility.NASA/Brandon Torres Navarrete To test these new technologies, Boeing brought a custom single-engine test plane to the airfield. Working from FutureFlight Central, their researchers developed simulated taxiway instructions and deployed them to the test pilot’s digital tablet and the autonomous system.
Typically, taxiing requires verbal communication between an air traffic controller and a pilot. Boeing’s digital taxi release system displays visual turn-by-turn routes and directions directly on the pilot’s digital tablet.
“This project with Boeing lends credibility to the research being done across Ames,” said Adam Yingling, autonomy researcher for the Air Traffic Management-eXploration (ATM-X) program at NASA Ames. “We have a unique capability with our proximity to Moffett and the work Ames researchers are doing to advance air traffic capabilities and technologies to support the future of our national airspace that opens the door to work alongside commercial operators like Boeing.”
The team’s autonomous taxiing tests allowed its aircraft to follow the air traffic control’s digital instructions to transit to the runway without additional pilot inputs.
Estela Buchmann, David Shapiro, and Maxim Mounier, members of the NASA Ames ATM-X project team, analyze results of Boeing’s digital taxi test at Ames’s FutureFlight Central facility.NASA/Brandon Torres Navarrete As commercial air travel increases and airspace gets busier, pilots and air traffic controllers have to manage heavier workloads. NASA is working with commercial partners to address those challenges through initiatives like its Air Traffic Management-eXploration project, which aims to transform air traffic management to accommodate new vehicles and air transportation options.
“In order to increase the safety and efficiency of our airspace operations, NASA research in collaboration with industry can demonstrate how specific functions can be automated to chart the course for enhancing traffic management on the airport surface,” said Shivanjli Sharma, ATM-X project manager at Ames.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The SWOT satellite is helping scientists size up flood waves on waterways like the Yellowstone River, pictured here in October 2024 in Montana. SWOT measures the height of surface waters, including the ocean, and hundreds of thousands of rivers, lakes, and reservoirs in the U.S. alone.NPS In a first, researchers from NASA and Virginia Tech used satellite data to measure the height and speed of potentially hazardous flood waves traveling down U.S. rivers. The three waves they tracked were likely caused by extreme rainfall and by a loosened ice jam. While there is currently no database that compiles satellite data on river flood waves, the new study highlights the potential of space-based observations to aid hydrologists and engineers, especially those working in communities along river networks with limited flood control structures such as levees and flood gates.
Unlike ocean waves, which are ordinarily driven by wind and tides, and roll to shore at a steady clip, river waves (also called flood or flow waves) are temporary surges stretching tens to hundreds of miles. Typically caused by rainfall or seasonal snowmelt, they are essential to shuttling nutrients and organisms down a river. But they can also pose hazards: Extreme river waves triggered by a prolonged downpour or dam break can produce floods.
“Ocean waves are well known from surfing and sailing, but rivers are the arteries of the planet. We want to understand their dynamics,” said Cedric David, a hydrologist at NASA’s Jet Propulsion Laboratory in Southern California and a coauthor of a new study published May 14 in Geophysical Research Letters.
SWOT is depicted in orbit in this artist’s concept, with sunlight glinting off one of its solar panels and both antennas of its key instrument — the Ka-band Radar Interferometer (KaRIn) — extended. The antennas collect data along a swath 30 miles (50 kilometers) wide on either side of the satellite.CNES Measuring Speed and Size
To search for river waves for her doctoral research, lead author Hana Thurman of Virginia Tech turned to a spacecraft launched in 2022. The SWOT (Surface Water and Ocean Topography) satellite is a collaboration between NASA and the French space agency CNES (Centre National d’Études Spatiales). It is surveying the height of nearly all of Earth’s surface waters, both fresh and salty, using its sensitive Ka-band Radar Interferometer (KaRIn). The instrument maps the elevation and width of water bodies by bouncing microwaves off the surface and timing how long the signal takes to return.
“In addition to monitoring total storage of waters in lakes and rivers, we zoom in on dynamics and impacts of water movement and change,” said Nadya Vinogradova Shiffer, SWOT program scientist at NASA Headquarters in Washington.
Thurman knew that SWOT has helped scientists track rising sea levels near the coast, spot tsunami slosh, and map the seafloor, but could she identify river height anomalies in the data indicating a wave on the move?
She found that the mission had caught three clear examples of river waves, including one that arose abruptly on the Yellowstone River in Montana in April 2023. As the satellite passed overhead, it observed a 9.1-foot-tall (2.8-meter-tall) crest flowing toward the Missouri River in North Dakota. It was divided into a dramatic 6.8-mile-long (11-kilometer-long) peak followed by a more drawn‐out tail. These details are exciting to see from orbit and illustrate the KaRIn instrument’s uniquely high spatial resolution, Thurman said.
Sleuthing through optical Sentinel-2 imagery of the area, she determined that the wave likely resulted from an ice jam breaking apart upstream and releasing pent-up water.
The other two river waves that Thurman and the team found were triggered by rainfall runoff. One, spotted by SWOT starting on Jan. 25, 2024, on the Colorado River south of Austin, Texas, was associated with the largest flood of the year on that section of river. Measuring over 30 feet (9 meters) tall and 166 miles (267 kilometers) long, it traveled around 3.5 feet (1.07 meters) per second for over 250 miles (400 kilometers) before discharging into Matagorda Bay.
The other wave originated on the Ocmulgee River near Macon, Georgia, in March 2024. Measuring over 20 feet (6 meters) tall and extending more than 100 miles (165 kilometers), it traveled about a foot (0.33 meters) per second for more than 124 miles (200 kilometers).
“We’re learning more about the shape and speed of flow waves, and how they change along long stretches of river,” Thurman said. “That could help us answer questions like, how fast could a flood get here and is infrastructure at risk?”
Complementary Observations
Engineers and water managers measuring river waves have long relied on stream gauges, which record water height and estimate discharge at fixed points along a river. In the United States, stream gauge networks are maintained by agencies including the U.S. Geological Survey. They are sparser in other parts of the world.
“Satellite data is complementary because it can help fill in the gaps,” said study supervisor George Allen, a hydrologist and remote sensing expert at Virginia Tech.
If stream gauges are like toll booths clocking cars as they pass, SWOT is like a traffic helicopter taking snapshots of the highway.
The wave speeds that SWOT helped determine were similar to those calculated using gauge data alone, Allen said, showing how the satellite could help monitor waves in river basins without gauges. Knowing where and why river waves develop can help scientists tracking changing flood patterns around the world.
Orbiting Earth multiple times each day, SWOT is expected to observe some 55% of large-scale floods at some stage in their life cycle. “If we see something in the data, we can say something,” David said of SWOT’s potential to flag dangerous floods in the making. “For a long time, we’ve stood on the banks of our rivers, but we’ve never seen them like we are now.”
More About SWOT
The SWOT satellite was jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and the UK Space Agency. NASA’s Jet Propulsion Laboratory, managed for the agency by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system payload, NASA provided the Ka-band radar interferometer (KaRIn) instrument, a GPS science receiver, a laser retroreflector, a two-beam microwave radiometer, and NASA instrument operations. The Doppler Orbitography and Radioposition Integrated by Satellite system, the dual frequency Poseidon altimeter (developed by Thales Alenia Space), the KaRIn radio-frequency subsystem (together with Thales Alenia Space and with support from the UK Space Agency), the satellite platform, and ground operations were provided by CNES. The KaRIn high-power transmitter assembly was provided by CSA.
