Introduction

Along the southernmost rim of the Florida Peninsula, the arching prop roots or “knees” of red mangroves (Rhizophora mangle) line the coast – see Photo 1. Where they dip below the water’s surface, fish lay their eggs, enjoying the protection from predators that the trees provide. Among their branches, wading birds, such as the great blue heron and the roseate spoonbill establish rookeries to rear their young. The tangled matrix of roots collects organic matter and ocean-bound sediments, adding little-by-little to the coastline and shielding inland biology from the erosive force of the sea. In these ways, mangroves are equal parts products and engineers of their environment, but their ecological value extends far beyond this local sphere of influence.

Mangroves are an important carbon dioxide (CO2) sink – responsible for removing CO2 from the atmosphere with impressive efficiency. Current estimates suggest mangroves sequester CO2 10 times faster and store up to 5 times more carbon than rainforests and old-growth forests. But as part of the ever-changing line between land and sea, they’re exceptionally vulnerable to climate disturbances such as sea level rise, hurricanes, and changes in ocean salinity. As these threats intensify, Florida’s sub-tropical wetlands – and their role as a critical sink of CO2 – face an uncertain future.  

NASA’s BlueFlux Campaign, a three-year (2021–2024), $1.5-million project operating under the agency’s Carbon Monitoring System, used field, aircraft, and satellite data to study the impact of both natural and anthropogenic pressures on South Florida’s coastal ecology. BlueFlux consists of a series of ground-based and airborne fieldwork campaigns, providing a framework for the development of a satellite-based data product that will estimate daily rates of surface-atmosphere gas transfer or gaseous flux across coastal ecosystems in Florida and the Caribbean. “The goal is to enhance our understanding of how blue-carbon ecosystems fit into the global carbon market,” said Ben Poulter [NASA’s Goddard Space Flight Center (GSFC)—Project Lead]. “BlueFlux will ultimately answer scientific questions and provide policy-related solutions on the role that coastal wetlands play in reducing atmospheric greenhouse gas (GHG) concentrations.”

This article provides an overview of BlueFlux fieldwork operations – see Figure 1 – and outlines how the project might help refine global GHG budgets and support the restoration of Florida’s wetland ecology.

BlueFlux Ground-based Fieldwork

Across the street from the Flamingo Visitors center, at the base of the Everglades National Park, there was once a thriving mangrove population. Now, the skeletal remains of the trees form one of the Everglades’ largest ghost forests – see Photo 2. When Hurricane Irma made landfall in September 2017, violent winds battered the shore and a storm surge swept across the coast, decimating large swaths of the mangrove forest. Most of Florida’s mangroves recovered swiftly. But seven years later, this site and others like it have seen little to no growth.

“At this point, I doubt they’ll ever recover,” said David Lagomasino [East Carolina University].

Lagomasino was in the Everglades this summer conducting research as part of the fifth leg of BlueFlux fieldwork – see Photo 3. His team focused on measuring how changes in wetland ecology affect the sequestration and emission rates of both CO2 and methane (CH4). In areas where vegetative health is severely degraded, like in ghost forests, a general decline in CO2 uptake is accompanied by an increase in CH4 production, the net effect of which could dramatically amplify the atmosphere’s ability to trap heat. Ghost forests offer an example at one end of an extreme, but defining the way more subtle gradients among wetland variables – such as changes in water level, tree height, canopy coverage, ocean salinity, or mangrove species distribution – might influence flux is harder to tease out of the limited data available.

Due to the relative inaccessibility of the region, measurements of flux in wetland ecosystems are limited. The plant life here consists almost entirely of Florida’s three Mangrove species (red, black, and white), which are among the only vegetation that can withstand the brackish waters characteristic of coastal wetlands.

In the Everglades, flux measurements are confined to a handful of eddy covariance towers – or flux towers – constructed as part of the National Science Foundation’s (NSF) Long-Term Ecological Research (LTER) Network. 

The first flux tower in this network, erected in June 2003, stands near the edge of Shark River at a research site called SRS-6, short for Shark River Slough site 6. A short walk from the riverbank, across a snaking path of rain-weathered, wooden planks, sits a small platform where the flux tower is anchored to the forest floor – see Photo 4. About 20 m (65 feet) above the platform, the tower breaches the canopy, where a suite of instruments continuously measures wind velocity, temperature, humidity, and the vertical movement of trace atmospheric gases, such as water vapor (H2Ov), CO2, and CH4. It’s these measurements collectively that are used to calculate flux.

The term eddy covariance refers to the statistical technique used to calculate gaseous flux based on the meteorological and scalar atmospheric data collected by the flux towers.

“Hundreds of research papers have come from this site,” said Lagomasino. The abundance of research generated from the data captured at SRS-6 speaks in part to the value of the measurements that the tower makes. It also points to the gaps that exist just beyond each tower’s reach. A significant goal of the BlueFlux campaign is to explain flux on a scale that isn’t covered by existing data – to fill in the gaps between the towers.

One way to do that is by gathering data by hand.

On Lagomasino’s boat is a broad, black case carrying a tool called a Russian peat auger. The instrument is designed to extract core samples from soft soils – see Photo 5.

Everglades peat, which is made almost entirely of the partially decomposed roots, stems, and leaves of the surrounding mangroves, offers a perfect study subject. Each thin, half-cylinder sample gets sealed and shipped back to the lab, where it will be sliced into flat discs. The discs will be analyzed for their age and carbon content by Lagomasino’s team and partners at Yale University. These cores are like biomass time capsules. In Florida’s mangrove forests, a 1-m (3-ft) core might represent more than 300 years of carbon accumulation. On average, a 1 to 3 mm (0.04 to 0.12 in) layer of matter is added to the forest floor each year, building up over time like sand filling an hourglass.

Although coastal wetlands account for less than 2% of the planet’s land-surface area, they house a disproportionate amount of blue carbon – carbon stored in marine and coastal environments. In the Everglades, the source of this immense accumulation of organic material is the quick-growing vegetation – see Photo 6.

When a CO2 molecule finds its way through one of the many small, porous openings on a mangrove leaf ­– called stomata – its next step is one of creation, where it plays a part in the miraculous transformation of inorganic matter into living tissue. Inside the leaf’s chloroplasts, energy from stored sunlight kickstarts a long chain of chemical reactions that will ultimately divide CO2 into its constituent parts. Oxygen atoms are returned to the atmosphere as the byproduct of photosynthesis, but the carbon stays behind to help build the sugar molecules that will fuel new plant growth. In short, the same carbon that once flowed through the atmosphere defines the molecular structure of all wetland vegetation. When a plant dies or a gust of wind pulls a leaf to the forest floor, this carbon-based matter finds its way into the soil, where it can stay locked in place for thousands of years thanks to a critical wetland ingredient: water.

The inundated, anoxic – an environment deficient or absent of oxygen – peat soils characteristic of wetlands host microbial populations that are uniquely adapted to their environment. In these low- to no-oxygen conditions, the prevailing microbiota consumes organic material slowly, leading to an accumulation of carbon in the soil. As wetland conditions change, the soil’s microbial balance shifts. For example, a decline in water level, which can increase the oxygen-content of the soil, produces conditions favorable to aerobic bacteria. These oxygen-breathing lifeforms consume organic matter far more rapidly than their anaerobic counterparts – and release more CO2 into the atmosphere as a result.

Water level isn’t the only environmental condition that influences rates of carbon sequestration. The soil cores collected during the campaign will be analyzed alongside records of interrelated variables such as water salinity, sea surface height, and temperature to understand not just the timescales associated with blue carbon development in mangrove forests but how and why rates of soil deposition change in response to specific environmental pressures. In many parts of the Everglades, accumulated peat can reach depths of up to 3 m (9.8 feet) – holding thousands of years’ worth of insights that would otherwise be lost to time.

Their propagules – or seedlings – germinate while still attached to their parent tree. Propagules that fall to the forest floor are primed to begin life as soon as they hit the ground. But even those that fall into bodies of water and are carried out to sea can float for months before finding a suitable place to lay their roots. The high growth rate of mangroves contributes to the efficiency with which mangrove forests remove CO2 from the atmosphere.

Lola Fatoyinbo [NASA’s Goddard Space Flight Center (GSFC), Biospheric Sciences Lab] and Peter Raymond [Yale University’s School of the Environment] led additional fieldwork teams tasked with collecting forest inventory data in locations where vegetation was dead, regenerating, or recently disturbed by severe weather events. A terrestrial laser system was used to obtain three-dimensional (3D) images of mangrove forest structure, which provided maps of stem density, vertical distributions of biomass, and stand volume surface area. Spectroradiometers were also used to acquire visible, near infrared, and shortwave infrared spectra, delivering detailed information about species composition, vegetative health, water levels, and soil properties.

To tie these variables to flux, the researchers made measurements using chambers – see Figure 2 – designed to adhere neatly to points where significant rates of gas exchange occur, (i.e., mangrove lenticels—cell-sized breathing pores found on tree bark and root systems— and the forest floor). As an example, black mangroves (Avicennia germinans) possess unique aerial roots called pneumatophores that, similar to the prop roots of red mangroves, provide them with access to atmospheric oxygen. Pneumatophores sprout vertically from the forest floor and line up like matchsticks around the base of each tree. The team used cylindrical chambers to measure the transfer of gas between a single pneumatophore and the atmosphere – see Figure 2a.

These observations are archived in NASA’s Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) and publicly available to researchers who wish to monitor and identify trends in the data. After nearly three years of field work, these data have already given scientists a more detailed picture of how Florida’s wetlands are responding to environmental pressures.

Research based on data from early BlueFlux fieldwork deployments confirms that aerobic, methanogenic microbes living in flooded, wetland soils naturally release a significant amount of CH4 as a byproduct of the process by which they create their own energy.

“We’re especially interested in this methane part,” said Fatoyinbo. “It’s the least understood, and there’s a lot more of it than we previously thought.” Fatoyinbo also noted a “significant difference in CO2 and CH4 fluxes between healthy mangroves and degraded ones.” In areas where mangrove health is in decline, due to reduced freshwater levels or as the result of damage sustained during severe weather events, “you can end up with more ‘bad’ gases in the atmosphere,” she said. Since CH4 is roughly 80 times more potent than CO2 over 100-year period, these emissions can undermine some of the net benefits that blue carbon ecosystems provide as a sink of atmospheric carbon.

Airborne Research Teams Measure GHG Flux from Above 

Florida’s mangrove forests blanket roughly 966 km2 (600 mi2) of coastal terrain. Even with over 20 years of tower data and the extensive measurements from ground-based fieldwork operations, making comprehensive inferences about the entire ecosystem is tenuous work. To provide flux data at scale – and help quantify the atmospheric influence that Florida’s coastal wetlands carry as a whole – NASA’s BlueFlux campaign relies on a relatively new, airborne technique for measuring flux – see Photo 7.

Between 2022 and 2024, over 5 deployments, the team conducted more than 34 carefully planned flights – see Figure 3 – collecting flux data over Florida’s wetlands by plane. Each flight is equipped with a payload known colloquially as “CARAFE,” short for the CARbon Airborne Flux Experiment, which is the airborne campaign’s primary means of data collection. “This is one of the first times an instrument like this has flown over a mangrove forest anywhere in the world,” said Fatoyinbo. “So, it’s really just kind of groundbreaking.”

Accurate flux calculations rely on stable measurements of the aircraft’s speed and orientation, which is why the flux legs of each flight are flown in straight lines.

In the air, GHG concentrations are measured using a well-established technique called cavity ringdown spectroscopy, which involves firing a laser into a small cavity where it will ping back and forth between two highly reflective mirrors. Most gas-phase molecules absorb light at specific wavelengths, depending on their atomic makeup. Since the target molecules in this case are CO2 and CH4, the laser is configured to emit light at a wavelength that only these molecules will absorb. As the laser bounces between the mirrors, a fraction of the light is absorbed by any molecules present in the chamber. The rate of the light’s decay is used to estimate CO2 and CH4 concentrations, generating a time series with continuous readings of gas concentrations, measured in parts per million – see Photo 8. This information is combined with measurements of vertical wind velocity to calculate a corresponding time series of fluxes along the flight track. While these measurements are important on their own, a priority for the airborne team is understanding GHG fluxes in relation to what’s happening on the ground.

The CARAFE payload is responsible for taking readings of atmospheric CO2, CH4, and H2Ov levels using a wind probe and two optical spectroscopy instruments manufactured by Picarro: the G2401m Gas Concentration Analyzer and the G2311f Gas Concentration Analyzer. The readings pictured above were made by the G2311f, which measures gas concentrations at a faster rate than the G2401m. The G2401m makes slower but more stable measurements, which are necessary for verifying the accuracy of measurements made by the G2311f.

Unlike flux towers, which only collect data within a 100 m2 (328 ft2) “footprint,” airborne readings have a footprint that can stretch up to 1 km (0.6 mi) in upwind directions. The plane’s speed, position, and orientation are used to help link flux data to fixed points along the flight’s path – so the team can make comparisons between aerial measurements and those made by the ground-based towers – see Photo 9.

“One challenge with that is the flux towers are much lower to the ground, and their footprint is much smaller,” said Glenn Wolfe [GSFC—BlueFlux Flight Lead]. “So, we have to be really careful with our airborne observations, to make sure they closely resemble our ground-based measurements.”

Part of decoding the airborne data involves overlaying each footprint with detailed maps of different surface properties, such as vegetation cover, soil water depth, or leaf-area index, so the team can constrain the measurements and assign fluxes to specific sources – whether its mangroves, sawgrass, or even water.

Data Upscaling – Making Daily Flux Predictions from Space

The coupling of BlueFlux’s ground-based and airborne data provides the framework for the production of a broader, regional image of GHG flux.

“The eddy flux towers give us information about the temporal variability,” said Cheryl Doughty [GSFC]. “And the airborne campaign gives us this great intermediate dataset that allows us to go from individual trees to a much larger area.”

Doughty is now using BlueFlux data to train a remote-sensing data product, the prototype of which is called Daily Flux Predictions for South Florida. The product’s underlying model relies on machine learning algorithms and an ensemble modeling technique called random forest regression. It will make flux predictions based on surface reflectance data captured by the Moderate Resolution Imaging Spectroradiometer (MODIS), an instrument that flies on NASA’s polar-orbiting Aqua and Terra satellites – see Figure 4.

“We’re really at the mercy of the data that’s out there,” said Doughty. “One of the things we’re trying to produce as part of this project is a daily archive of fluxes, so MODIS is an amazing resource, because it has over 20 years of data at a daily temporal resolution.”

This archival flux data will help researchers explain how fluxes change in relation to processes that are directly described by MODIS surface reflectance data, including sea-level rise, land use, water management, and disturbances from hurricanes and fires.

The model inputs rely on a composite of MODIS Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Radiance (NBAR) measurements from all available MODIS land bands: [top row, left to right]: red (620–670 nm), green (545–565 nm), blue (459–479 nm); [middle row, left to right] near infrared 1, or NIR1 (841–876 nm), NIR2 (1230–1250 nm), shortwave IR 1, or SWIR1 (1628–1652 nm), and SWIR 2 (2105–2155 nm). The Everglades National Park boundary is indicated on each image with a white line. Output of the model is shown [bottom row, left] as well as a comparison between modeled fluxes of MODIS NBAR with Terra and Aqua [bottom row, right].

To help validate the model, researchers must reformat flux measurements from the airborne campaign to match the daily temporal resolution and 500m2 (0.3mi2) spatial resolution of MODIS reflectance retrievals.

“It’s best practice to meet the data at the coarsest resolution,” said Doughty. “So, we have to take an average of the hourly estimates to match MODIS’ daily scale.”

The matching process is slightly more complicated for spatial datasets. BlueFlux’s airborne flux measurements produce roughly 20 data points for each 500 m2 (0.3 mi2) area, the same resolution as a single MODIS pixel.

“We’re essentially taking an average of all those CARAFE points to get an estimate that corresponds to one pixel,” said Doughty.

This symmetry is critical, allowing the team to test, train, and tune the model using measurements that capture what’s really happening on the ground – ensuring the accuracy of flux measurements generated from satellite data alone.

Researchers don’t expect the model to serve as a perfect reconstruction of reality. The heterogenous nature of Florida’s wetland terrain – which consists of a patchwork of sawgrass marshland, mangrove forests, hardwood hammocks, and freshwater swamps – contributes to high degree of variability in CO2 removal rates within and across its distinct regions. The daily flux product accounts for some of this complexity by making hundreds of calculations at a time, each with slightly different parameters based on in-situ measurements.

“The goal isn’t to just give people one flux measurement but an estimate of the uncertainty that is so inherent to these wetlands,” explained Doughty.

The prototype of the product will be operational by early 2025 and accessible to the public through NASA’s ORNL­ DAAC. Doughty hopes it will help stakeholders and decision makers evaluate policies related to water management, land use, and conservation that might impact critical stocks of blue carbon. 

From Drainage to Restoration in the Florida Everglades

In the late 19th century, land developers were drawn to South Florida, where they hoped the fertile soil and tropical climate could support year-round cultivation of commodities such as exotic fruits, vegetables, and sugar cane. There was just one thing standing in the way – the water. If they could find a way to tame Florida’s wilderness, to drain the wetland of its excess water, Florida would offer Americans a new agricultural frontier.

Progress was made incrementally, but the Everglades drainage project idled for more than 50 years as its organizers wrestled with the literal and political morass surrounding South Florida’s wetland topography. It was mother nature’s hand that ultimately accelerated the drainage project. In 1926 and 1928, two large hurricanes tore through the barrier along Lake Okeechobee’s southern shore built to prevent water from spilling onto the newly settled, small-scale farmland just south of the lake. The second of the two storms – 1928’s Okeechobee Hurricane – made landfall in early September and resulted in nearly 3,000 recorded fatalities. In some areas, the torrent of flood water was deep enough that even those who sought refuge from the flood on the roofs of their homes were swept away by the current. The federal government was forced to step in.

By 1938, the U.S. Army Corps of Engineers had completed construction of the Hoover Dike, adding to a collection of four canals responsible for siphoning water away from Lake Okeechobee’s floodplain and into the Atlantic Ocean. Seasonal flooding was brought under control, but the complete reclamation of South Florida’s wetlands proved more challenging than anticipated. As water levels fell and freshly cleared lands dried out, the high organic content of the soil fueled tremendous peat and muck fires that could burn for days, spreading through underground seams where water once flowed. In some areas, fires consumed the entire topsoil layer – exposing the limestone substrata to the atmosphere for the first time in thousands of years. The engineers in charge of Florida’s early wetland reclamation projects underestimated the value of the state’s hydrological system and overestimated its capacity to withstand human interference. 

“Those initial four canals were enough to drain the everglades three times over,” said Fred Sklar [South Florida Water Management District—Everglades System Sciences Director]. “And they still exist, but now there are more than seven million people who rely on them for drinking water and flood control.”

Today, much of the Water Management District’s work involves unwinding the damage wrought by earlier drainage efforts.

“One thing we’re trying to do is make sure these peat fires never happen again,” said Sklar.

But restoring natural water flow to the Everglades ­– which is critical to the region’s ecological health – isn’t an option. Even if drainage could be reversed, it would subject Florida’s residents to the same flood risks that made drainage a priority. Some residents, including members of the Miccosukee and Seminole tribes, live directly alongside or within Everglades wilderness areas, where the risk of flooding is even greater than it is in the state’s highly populated coastal communities. These areas are also out of reach of the Water Management District’s existing infrastructure. It’s not as simple as turning the tap on and off.

Blueflux Photo 10
Photo 10. The Tamiami Trail Canal runs across the Florida Peninsula from west to east, towards a saltwater treatment facility near the Miami River. Construction was completed in 1928, shortly after the first four drainage canals opened. It quickly became apparent that the canal and its adjacent roadway dramatically impede water flow to the Everglades wilderness areas to their south, cutting off the region’s vegetation and wildlife from a critical source of freshwater. New modifications to the canal are currently underway, which aim to introduce a hydrological regime that more closely resembles the pre-drainage system.

Florida’s Water Management District works with federal agencies, including the U.S. Army Corps of Engineers, to monitor and govern the flow of Florida’s freshwater. The District has overseen the construction and management of dozens of canals, dikes, levees, dredges, and pumps over the last half-century that offer a higher degree of control over Florida’s complex hydrological network – see Photo 10.

“The goal is to restore as much acreage as we can, but we also need to restore it functionally, without degrading the whole system or putting residents at risk,” summarized Sklar. “To do this effectively, we need a detailed understanding of how the hydrology functions and how it influences all of these other systems, such as carbon sequestration.”

Since the 1920s, more than half of Florida’s original wetland coverage has been lost. The present system also carries 65% less peat coverage and 77% less stored carbon than it did prior to drainage. As atmospheric CO2 concentrations climb at unprecedented rates, an accompanying rise in sea levels, severe weather, and ocean salinity all present serious threats to Florida’s wetland ecology – see Figure 5.

“We’re worried about losing that stored carbon,” said Poulter. “But blue carbon also offers tremendous opportunities for climate mitigation if conservation and restoration are properly supported by science.”

Conclusion – The Future of Flux

Every few years, the Intergovernmental Panel on Climate Change (IPCC) releases emissions data and budget reports that have important policy implications related to the Paris Agreement’s goal of limiting global warming to between 1.5°C (2.7°F) and 2°C (3.6°F) compared to pre-industrial levels. Refining the accuracy of global carbon budgets is paramount to reaching that goal, and wetland ecosystems – which have been historically under-represented in climate research – are an important part of the equation.

Early estimates based on BlueFlux fieldwork deployments and upscaled using MODIS surface reflectance data suggest that wetland CH4 emissions in South Florida offset CO2 removal in the region by about 5% based on a 100-year CH4 warming potential, resulting in a net annual CO2 removal of 31.8 Tg (3.18 million metric tons) per year. This is a small fraction of total CO2 emissions in the U.S. and an even smaller fraction of global emissions. In 2023, an estimated 34,800 Tg (34.8 billion metric tons) of CO2 were released into the atmosphere. But relative to their size, the CO2 removal services provided by tropical wetlands are hardly dismissible.

“We’re finding that massive amounts of CO2 are removed and substantial amounts of CH4 are produced, but overall, these ecosystems provide a net climate benefit by removing more greenhouse gases than they produce,” Poulter said.

Access to a daily satellite data product also provides researchers with the means to make more regular adjustments to budgets based on how Florida’s mutable landscape is responding to climate disturbances and restoration efforts in real time.

With the right resources in hand, the scientists who dedicate their careers to understanding and restoring South Florida’s ecology share a hopeful outlook.

“Nature and people can absolutely coexist,” said Meenakshi Chabba [The Everglades Foundation—Ecologist and Resilience Scientist]. “But what we need is good science and good management to reach that goal.”

The Everglades Foundation provides scientific evaluation and guidance to the elected officials and governmental institutions responsible for the implementation of the Comprehensive Everglades Restoration Plan (CERP), a federal program approved by Congress in 2000 that outlines a 30-year plan to restore Florida’s wetland ecology. The Foundation sees NASA’s BlueFlux campaign as an important accompaniment to that goal.

“The [Daily Flux Predictions for South Florida] data product is incredibly valuable, because it provides us with an indicator of the health of the whole system,” said Steve Davis [The Everglades Foundation—Chief Science Officer]. “We know how valuable the wetlands are, but we need this reliable science from NASA and the BlueFlux Campaign to help translate those benefits into something we can use to reach people as well as policymakers.”

Researchers hope the product can inform decisions about the management of Florida’s wetlands, the preservation of which is not only a necessity but – to many – a responsibility.

“These impacts are of our own doing,” added Chabba. “So, now it’s incumbent upon us to make these changes and correct the mistakes of the past.”

Next, the BlueFlux team is shifting their focus to what they call BlueFlux 2. This stage of the project centers around further analysis of the data collected during fieldwork campaigns and outlines the deployment of the beta version of Daily BlueFlux Predictions for South Florida, which will help generate a more accurate evaluation of flux for the many wetland ecosystems that exist beyond Florida’s borders.

“We’re trying to contribute to a better understanding of global carbon markets and inspire further and more ambitious investments in these critical stocks of blue carbon,” said Poulter. “First, we want to scale this work to the Caribbean, where we have these great maps of mangrove distribution but limited data on flux.”

An additional BlueFlux fieldwork deployment is slated for 2026, with plans to make flux measurements above sites targeted by the state for upcoming restoration initiatives, such as the Everglades Agricultural Area Environmental Protection District. In the Agricultural Area, construction is underway on a series of reservoirs that will store excess water during wet seasons and provide a reserve source of water for wildlife and residents during dry seasons. As the landscape evolves, BlueFlux will help local officials evaluate how Florida’s wetlands are responding to efforts designed to protect the state’s most precious natural resource – and all those who depend on it.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Drones were a key part of testing new technology in support of a prescribed burn in Geneva State Forest, which is about 100 miles south of Montgomery, Alabama. The effort is part of the agency’s multi-year FireSense project, which is aimed at testing technologies that could eventually serve the U.S. Forest Service as well as local, state, and other federal wildland fire agencies.

This information could improve wildland fire decision making and enable operational agencies to better allocate firefighters and resources. A small team from NASA’s Armstrong Flight Research Center in Edwards, California, is demonstrating how some of these technologies work.
      Two instruments from NASA’s Langley Research Center in Hampton, Virginia – a sensor gathering 3D wind data and a radiosonde that measures temperature, barometric pressure, and humidity data – were installed on NASA Armstrong’s Alta X drone for a prescribed burn in Geneva State Forest, which is about 100 miles south of Montgomery, Alabama. The effort is part of the agency’s multi-year FireSense project, which is aimed at testing technologies that could eventually serve the U.S. Forest Service as well as local, state, and other federal wildland fire agencies.
      “The objectives for the Alta X portion of the multi-agency prescribed burn include a technical demonstration for wildland fire practitioners, and data collection at various altitudes for the Alabama Forestry Commission operations,” said Jennifer Fowler, FireSense project manager. “Information gathered at the different altitudes is essential to monitor the variables for a prescribed burn.”
      Those variables include the mixing height, which is the extent or depth to which smoke will be dispersed, a metric Fowler said is difficult to predict. Humidity must also be above 30% for a prescribed burn. The technology to collect these measurements locally is not readily available in wildland fire operations, making the Alta X and its instruments key in the demonstration of prescribed burn technology.

Sensors onboard other aircraft supporting the mission will fly at lower altitudes during the fire, and at higher altitudes before and after the fire for required data collection. The multi-agency mission will provide data to confirm and adjust the prescribed burn forecast model.
      Small, uncrewed aircraft system pilots from NASA Armstrong completed final preparations to travel to Alabama and set up for the research flights. The team – including Derek Abramson, chief engineer for the subscale flight research laboratory; Justin Hall, NASA Armstrong chief pilot of small, uncrewed aircraft systems; and Alexander Jaffe, a drone pilot – will set up, fly, observe airborne operations, all while keeping additional aircraft batteries charged. The launch and recovery of the Alta X is manual, the mission profile is flown autonomously to guarantee the same conditions for data collection.
      “The flight profile is vertical – straight up and straight back down from the surface to about 3,000 feet altitude,” Abramson said. “We will characterize the mixing height and changes in moisture, mapping out how they both change throughout the day in connection with the burn.”
      In August 2024, a team of NASA researchers used the NASA Langley Alta X and weather instruments in Missoula, Montana, for a FireSense project drone technology demonstration. These instruments were used to generate localized forecasting that provides precise and sustainable meteorological data to predict fire behavior and smoke impacts.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      A Massachusetts Institute of Technology Lincoln Laboratory pilot controls a drone during NASA’s In-Time Aviation Safety Management System test series in collaboration with a George Washington University team July 17-18, 2024, at the U.S. Army’s Fort Devens in Devens, Massachusetts. MIT Lincoln Laboratory/Jay Couturier From agriculture and law enforcement to entertainment and disaster response, industries are increasingly turning to drones for help, but the growing volume of these aircraft will require trusted safety management systems to maintain safe operations.
      NASA is testing a new software system to create an improved warning system – one that can predict hazards to drones before they occur. The In-Time Aviation Safety Management System (IASMS) will monitor, assess, and mitigate airborne risks in real time. But making sure that it can do all that requires extensive experimentation to see how its elements work together, including simulations and drone flight tests.
      “If everything is going as planned with your flight, you won’t notice your in-time aviation safety management system working,” said Michael Vincent, NASA acting deputy project manager with the System-Wide Safety project at NASA’s Langley Research Center in Hampton, Virginia. “It’s before you encounter an unusual situation, like loss of navigation or communications, that the IASMS provides an alert to the drone operator.”
      The team completed a simulation in the Human-Autonomy Teaming Laboratory at NASA’s Ames Research Center in California’s Silicon Valley on March 5 aimed at finding out how critical elements of the IASMS could be used in operational hurricane relief and recovery.
      During this simulation, 12 drone pilots completed three 30-minute sessions where they managed up to six drones flying beyond visual line of sight to perform supply drops to residents stranded after a severe hurricane. Additional drones flew scripted search and rescue operations and levee inspections in the background. Researchers collected data on pilot performance, mission success, workload, and perceptions of the experiences, as well as the system’s usability.
      This simulation is part of a longer-term strategy by NASA to advance this technology. The lessons learned from this study will help prepare for the project’s hurricane relief and recovery flight tests, planned for 2027.  
      As an example of this work, in the summer of 2024 NASA tested its IASMS during a series of drone flights in collaboration with the Ohio Department of Transportation in Columbus, Ohio, and in a separate effort, with three university-led teams.
      For the Ohio Department of Transportation tests, a drone flew with the NASA-developed IASMS software aboard, which communicated back to computers at NASA Langley. Those transmissions gave NASA researchers input on the system’s performance.
      Students from the Ohio State University participate in drone flights during NASA’s In-Time Aviation Safety Management System test series in collaboration with the Ohio Department of Transportation from March to July 2024 at the Columbus Aero Club in Ohio. NASA/Russell Gilabert NASA also conducted studies with The George Washington University (GWU), the University of Notre Dame, and Virginia Commonwealth University (VCU). These occurred at the U.S. Army’s Fort Devens in Devens, Massachusetts with GWU; near South Bend, Indiana with Notre Dame; and in Richmond, Virginia with VCU. Each test included a variety of types of drones, flight scenarios, and operators.
      Students from Virginia Commonwealth University walk toward a drone after a flight as part of NASA’s In-Time Aviation Safety Management System (IASMS) test series July 16, 2024, in Richmond, Virginia. NASA/Dave Bowman Each drone testing series involved a different mission for the drone to perform and different hazards for the system to avoid. Scenarios included, for example, how the drone would fly during a wildfire or how it would deliver a package in a city. A different version of the NASA IASMS was used to fit the scenario depending on the mission, or depending on the flight area.
      Students from the University of Notre Dame prepare a small drone for takeoff as part of NASA’s In-Time Aviation Safety Management System (IASMS) university test series, which occurred on August 21, 2024 in Notre Dame, Indiana.University of Notre Dame/Wes Evard When used in conjunction with other systems such as NASA’s Unmanned Aircraft System Traffic Management, IASMS may allow for routine drone flights in the U.S. to become a reality. The IASMS adds an additional layer of safety for drones, assuring the reliability and trust if the drone is flying over a town on a routine basis that it remains on course while avoiding hazards along the way.
      “There are multiple entities who contribute to safety assurance when flying a drone,” Vincent said. “There is the person who’s flying the drone, the company who designs and manufactures the drone, the company operating the drone, and the Federal Aviation Administration, who has oversight over the entire National Airspace System. Being able to monitor, assess and mitigate risks in real time would make the risks in these situations much more secure.”
      All of this work is led by NASA’s System-Wide Safety project under the Airspace Operations and Safety program in support of the agency’s Advanced Air Mobility mission, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.

      She Speaks for the Samples: Meet Dr. Juliane Gross, Artemis Campaign Sample Curation Lead 
      By NASA
      Based at NASA’s Johnson Space Center in Houston, the Astromaterials Research and Exploration Science Division, or ARES, curates the most extensive collection of extraterrestrial materials on Earth, ranging from microscopic cosmic dust particles to Apollo-era Moon rocks. Soon, ARES’ team of world-leading sample scientists hopes to add something new to its collection – lunar samples from the Moon’s South Pole region. 

      As the Artemis campaign sample curation lead, Dr. Juliane Gross is helping ARES and NASA prepare to collect and return those samples safely. “I’m responsible for representing the voice of the Moon rocks and advocating for their protection, preservation, and maintaining their integrity during the planning and execution of all stages of the different Artemis sample return missions,” she said. 
      Juliane Gross leads a geology lesson for Artemis II crew members as part of their field training in Iceland in 2024.NASA Her multifaceted role includes preparing the Johnson facility that will receive new lunar samples, developing curation strategies, and collaborating with mission teams to plan sampling operations, which encompass collection, handling, transport, and storage processes for all stages of Artemis missions. She trains program managers and engineers on the importance of sample return and teaches crew members how to identify lunar samples and collect them without contamination. She also works with the different programs and teams that oversee the vehicles used at different stages of lunar missions – collaborating with the human landing system team around tool storage and delivery to the lunar surface, the Orion Program to coordinate sample stowage for the return to Earth, and Exploration Ground Systems to plan sample recovery after splashdown.  

      Once samples are returned to Earth, Gross and the ARES curation team will conduct a preliminary examination of the materials and release a sample catalog from which members of the global scientific community may request loans to carry out their respective research. 

      Working across Artemis teams raised an unexpected but fun challenge for Gross – learning to communicate effectively with colleagues who have different academic and professional backgrounds. “Scientists like me speak a different language than engineers, and we all speak a different language than managers or the general public,” she said. “I have worked hard to find common vocabulary and to ‘translate’ science needs into the different types of languages that exist within the Artemis campaign. I’m trying to use our differences as strengths to enable mission success and to connect and build relationships with all these different teams through my love and passion for the Moon and rocks from the Moon.” 

      That passion emerged shortly after Gross completed her Ph.D. in geology, while working on lunar samples with the Lunar and Planetary Institute. She went on to become a research scientist with the American Museum of Natural History in New York, and then a tenured professor of planetary sciences at Rutgers University in Piscataway, New Jersey.  

      In 2019, NASA asked Gross to join the Apollo Next Generation Sample Analysis Program. Under the program, NASA preserved some of the 382 kilograms of lunar samples returned by Apollo missions, keeping them sealed for future generations to open and analyze. “NASA had the foresight to understand that technology would evolve and our level of sophistication for handling and examining samples would greatly increase,” Gross said.  

      She and two other scientists had the incredible opportunity to open and examine two samples returned by Apollo 17. Their work served as a practice run for Artemis sample returns while building upon the fundamental insights into the shared origin and history of Earth and the Moon that scientists previously derived from other Apollo samples. For example, the team extracted gas from one sample that will provide information about the volatiles that future lunar missions may encounter around the Moon’s South Pole.  

      “The Apollo Next Generation Sample Analysis Program linked the first generation of lunar explorers from Apollo with future explorers of the Moon with Artemis,” Gross said. “I’m very proud to have played such an important role in this initiative that now feeds forward to Artemis.” 
      Juliane Gross examines lunar samples returned by Apollo 17 in Johnson Space Center’s Lunar Sample Laboratory Facility. NASA Gross’ connection with NASA began even earlier in her career. She was selected to join the agency-sponsored Antarctic Search for Meteorites team and lived in the deep ice fields of Antarctica for two months with seven other people. “We lived in tiny two-person tents without any support and recovered a total of 263 space rocks under challenging conditions,” she said. “I experienced the powerful forces of Antarctica and traveled 332 miles on skidoos. My body changed in the cold – I stuffed my face with enough butter, chocolate, and peanut M&Ms to last a lifetime and yet I lost weight.”  

      This formative experience taught Gross to find and celebrate beauty, even in her toughest moments. “I drank tea made with Antarctic glacier ice that is thousands to millions of years old. I will never forget the beautiful bell-like sounds that snow crystals make when being blown across the ice, the rainbow-sparkling ice crystals on a really cold day, the vast expanses of ice sheets looking like oceans frozen in eternity, and the icy bite of the wind on any unprotected skin that made me feel so alive and reminded me how vulnerable and precious life is,” she said. “And I will never ever forget the thrill and utter joy of finding a meteorite that you know no one on this planet has ever seen before you.”  

      Gross ultimately received the Antarctica Service Medal of the United States Armed Forces from the U.S. Department of Defense for her work. 
      Juliane Gross returns to McMurdo Station in Antarctica after working in the deep field for two months as part of the Antarctic Search for Meteorites team.Image courtesy of Juliane Gross Transitioning from full-time academia to her current position at NASA has been a big adjustment for Gross, but she has learned to love the change and the growth opportunities that come with it. “Being part of this incredible moment in history when we are about to return to the Moon with Artemis, our Apollo of today, feels so special and humbling that it made the transition easier,” she said.  

      The job has also increased Gross’ love and excitement for space exploration and reminds her every day why sample return missions are important. “The Moon is a museum of planetary history,” she said. “It has recorded and preserved the changes that affected the Earth-Moon system and is the best and most accessible place in the solar system to study planet-altering processes that have affected our corner of the universe.”  

      Still, “The Moon is only our next frontier,” she said. “Keep looking up and never give up. Ad astra!”

      NASA Demonstrates New Wildland Fire Airspace Management System
      By NASA
      5 min read
      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Advanced Capabilities for Emergency Response Operations (ACERO) researchers Lynne Martin, left, and Connie Brasil use the Portable Airspace Management System (PAMS) to view a simulated fire zone and set a drone flight plan during a flight test the week of March 17, 2025.NASA/Brandon Torres-Navarrete NASA researchers conducted initial validation of a new airspace management system designed to enable crews to use aircraft fight and monitor wildland fires 24 hours a day, even during low-visibility conditions.  
      From March 17-28, NASA’s Advanced Capabilities for Emergency Response Operations (ACERO) project stationed researchers at multiple strategic locations across the foothills of the Sierra de Salinas mountains in Monterey County, California. Their mission: to test and validate a new, portable system that can provide reliable airspace management under poor visual conditions, one of the biggest barriers for aerial wildland firefighting support. 
      The mission was a success. 
      “At NASA, we have decades of experience leveraging our aviation expertise in ways that improve everyday life for Americans,” said Carol Carroll, deputy associate administrator for NASA’s Aeronautics Research Mission Directorate at agency headquarters in Washington. “We need every advantage possible when it comes to saving lives and property when wildfires affect our communities, and ACERO technology will give responders critical new tools to monitor and fight fires.” 
      NASA ACERO researchers Samuel Zuniga,left, and Jonathan La Plain prepare for a drone flight test using the PAMS in Salinas on March 19, 2025.NASA/Brandon Torres-Navarrete One of the barriers for continued monitoring, suppression, and logistics support in wildland fire situations is a lack of tools for managing airspace and air traffic that can support operations under all visibility conditions. Current aerial firefighting operations are limited to times with clear visibility when a Tactical Air Group Supervisor or “air boss” in a piloted aircraft can provide direction. Otherwise, pilots may risk collisions. 
      The ACERO technology will provide that air boss capability for remotely piloted aircraft operations – and users will be able to do it from the ground. The project’s Portable Airspace Management System (PAMS) is a suitcase-sized solution that builds on decades of NASA air traffic and airspace management research. The PAMS units will allow pilots to view the locations and operational intents of other aircraft, even in thick smoke or at night. 
      During the testing in Salinas, researchers evaluated the PAMS’ core airspace management functions, including strategic coordination and the ability to automatically alert pilots once their aircrafts exit their preapproved paths or the simulated preapproved fire operation zone.  
      Using the PAMS prototype, researchers were able to safely conduct  flight operations of a vertical takeoff and landing aircraft operated by Overwatch Aero, LLC, of Solvang, California, and two small NASA drones. 
      Flying as if responding to a wildfire scenario, the Overwatch aircraft connected with two PAMS units in different locations. Though the systems were separated by mountains and valleys with weak cellular service, the PAMS units were able to successfully share and display a simulated fire zone, aircraft location, flight plans, and flight intent, thanks to a radio communications relay established by the Overwatch aircraft.  
      Operating in a rural mountain range validated that PAMS could work successfully in an actual wildland fire environment.   
      “Testing in real mountainous environments presents numerous challenges, but it offers significantly more value than lab-based testing,” said Dr. Min Xue, ACERO project manager at NASA’s Ames Research Center in California’s Silicon Valley. “The tests were successful, providing valuable insights and highlighting areas for future improvement.”
      NASA ACERO researchers fly a drone to test the PAMS during a flight test on March 19, 2025.NASA/Brandon Torres-Navarrete Pilots on the ground used PAMS to coordinate the drones, which performed flights simulating aerial ignition – the practice of setting controlled, intentional fires to manage vegetation, helping to control fires and reduce wildland fire risk. 
      As a part of the testing, Joby Aviation of Santa Cruz, California, flew its remotely piloted aircraft, similar in size to a Cessna Grand Caravan, over the testing site. The PAMS system successfully exchanged aircraft location and flight intent with Joby’s mission management system. The test marked the first successful interaction between PAMS and an optionally piloted aircraft. 
      Fire chiefs from the California Department of Forestry and Fire Protection (CAL FIRE) attended the testing and provided feedback on the system’s functionality, features that could improve wildland fire air traffic coordination, and potential for integration into operations. 
      “We appreciate the work being done by the NASA ACERO program in relation to portable airspace management capabilities,” said Marcus Hernandez, deputy chief for CAL FIRE’s Office of Wildfire Technology. “It’s great to see federal, state, and local agencies, as it is important to address safety and regulatory challenges alongside technological advancements.” 
      ACERO chief engineer Joey Mercer, right, shows the Portable Airspace Management System (PAMS) to Cal Fire representatives Scott Eckman, center, and Pete York, left, in preparation for the launch of the Overwatch Aero FVR90 Vertical Take Off and Landing (VTOL) test “fire” information sharing, airspace management, communication relay, and aircraft deconfliction capabilities during the Advanced Capabilities for Emergency Response Operations (ACERO) test in Salinas, California.NASA/Brandon Torres-Navarrete These latest flights build on successful PAMS testing in Watsonville, California, in November 2024. ACERO will use flight test data and feedback from wildland fire agencies to continue building out PAMS capabilities and will showcase more robust information-sharing capabilities in the coming years.  
      NASA’s goal for ACERO is to validate this technology, so it can be developed for wildland fire crews to use in the field, saving lives and property. The project is managed by NASA’s Airspace Operations and Safety Program and supports the agency’s  Advanced Air Mobility mission.
