NASA Aircraft Coordinate Science Flights to Measure Air Quality

Magic is in the air. No wait… MAGEQ is in the air, featuring scientists from NASA centers across the country who teamed up with the National Oceanic and Atmospheric Administration (NOAA), the University of Maryland Baltimore County, and several other university and government partners and collaborators.

This summer, six planes collectively flew more than 400 hours over the mid-Atlantic United States with a goal of gathering data on a range of objectives, including air quality, forestry, and fire management.

This was part of an effort called MAGEQ, short for Mid-Atlantic Gas Emissions Quantification. Rather than one mission, MAGEQ consists of several individual missions across more than a dozen organizations and agencies, along with university students. Over the course of around six weeks, aircraft flew over cities, wetlands, farms, and coal mining areas.

“Each aircraft team is comprised of highly skilled and motivated people who understand how to fly their particular plane to achieve the science they want,” said Glenn Wolfe, research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and project lead for MAGEQ. “The complexity comes in identifying how each platform can complement or supplement the others.”

Coordinating flights required both advanced planning and flexibility to get the best outcome. Weather proved to be a primary challenge for the team, as members worked around cloudy days, wind, and storms to ensure safe flights.

The six aircraft had different objectives and requirements. For example, some carried instruments that needed to fly high to simulate a satellite’s view of the atmosphere and the Earth’s surface and could not measure through clouds. Others were equipped with instruments that directly measured the air particles and could work under the clouds, provided there was no rain.

Despite weather challenges, flight teams worked together to coordinate as many multi-aircraft flight days as possible, meeting the overall objective of the MAGEQ campaign.

“It’s been inspiring to see how everybody worked together,” said Lesley Ott, research meteorologist and lead carbon cycle modeler for NASA’s Global Modeling and Assimilation Office at NASA Goddard. “By collecting data together, not only can we do a better job as scientists in having more complete understanding, we can also do a better job making usable data sets that meets the needs of different stakeholders.”

State resource managers in North Carolina and Virginia, for example, could benefit from this data as they monitor the health of wetlands, which provide resilience to storms, absorb carbon from the atmosphere and support local tourist industries. The data could also help operators at energy-producing facilities detect methane leaks or equipment failures quickly. Faster detection could speed up intervention and minimize waste, as well as lessen environmental impacts. Stakeholders were an integral part of the planning process, Ott said. They made suggestions about measurement sites and data needs that informed the flight planning.

Scientists will also use the measurements to verify satellite data from both public and commercial data providers. Satellites like the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument collect similar data. Scientists can compare the airborne and satellite data to get a more complete picture of the atmosphere. They also will use MAGEQ data to evaluate atmospheric chemistry modeling from the Goddard Earth Observing System (GEOS) model, which connects atmospheric, oceanic, and land data to help create a more comprehensive picture of Earth science.

“Every aircraft does something different and contributes a different type of data,” said Steve Brown, leader of the tropospheric chemistry and atmospheric remote sensing programs at the NOAA Chemical Sciences Laboratory in Boulder, Colorado. “We’re going to have a lot of work to do at the end of this to put all these data sets together, but we will make the best use of all these measurements.”

NASA Data Powers New Tool to Protect Water Supply After Fires

NASA Data Powers New Tool to Protect Water Supply After Fires

When wildfires scorch a landscape, the flames are just the beginning. NASA is helping communities across the nation foresee and prepare for what can follow: mudslides, flash flooding, and contaminated surface water supplies.

A new online tool called HydroFlame, built with support from NASA’s Earth Science Division, relies on satellite data, hydrologic modeling, and artificial intelligence to predict how wildfires could affect water resources, from tap water to the rivers and streams where people fish. The project is being developed with the University of Texas at Arlington, Purdue University, the U.S. Geological Survey, and other partners.

For now, the tool includes data only for Montana’s Clark Fork Basin, where it is being piloted. But new applications are underway in California and Utah. Researchers will soon begin fieldwork in Los Angeles County to collect on-the-ground data to refine HydroFlame’s predictive approach — an important step toward expanding it beyond the pilot site.

“As wildfires intensify across the country, so do their ripple effects on regional water resources,” said Erin Urquhart, program manager for NASA’s water resources program at NASA Headquarters in Washington. “HydroFlame could help communities in the U.S. see what’s coming and plan for it, before a fire becomes a water crisis.”

That kind of foresight is exactly what local officials are looking for.

“For someone managing a trout fishery or drinking water supply, knowing when a stream might be overwhelmed with debris after a fire can mean the difference between preparedness and a crisis,” said Morgan Valliant, who is part of the project’s advisory group and the associate director of ecosystem services for Missoula Parks and Recreation in Montana. “This tool could let us move from reacting to planning.”

When fire reshapes land

In the wake of a wildfire, charred hillsides are often unstable. With the protective blanket of plants burned away, rain that once soaked gently into the soil can race downhill, sending ash, debris, and sediment into rivers and reservoirs. That runoff can trigger flash floods and contaminate drinking water.

Severe wildfires can also bake soil into a water-repelling crust. With less absorption, the same slopes can swing from drought to destructive floods, and those runoff risks can persist for decades.

HydroFlame, developed by a team led by Adnan Rajib at the University of Texas at Arlington, is built to anticipate those extremes.

“NASA is constantly pushing the boundaries when it comes to sensing and predicting fire,” Rajib said. “But there is still a huge gap when it comes to translating that fire information in terms of water. That’s where HydroFlame comes in.” 

The tool will include three components:

• a historical viewer that maps past fire impacts on streamflow and sediment
• a “what-if” scenario builder to simulate future fires
• a predictive tool that generates weekly forecasts using near-real-time satellite data as initial conditions

When a wildfire is identified, the tool will identify how severely areas are burned across watersheds and track shifts in vegetation, soil wetness, and evapotranspiration, or the release of water from the land and plants to the atmosphere. HydroFlame uses data from satellite missions and instruments including MODIS (Moderate Resolution Imaging Spectroradiometer), Landsat, and SMAP (Soil Moisture Active Passive).

Those observations, combined with stream records from gauged rivers, feed into simulations of possible fire-driven changes in water flow and quality. A machine-learning component will fill in where gauges are absent, making it possible to predict impacts up to two weeks in advance.

The historical viewer, which is publicly accessible, lets users explore how past fires altered streamflow and sediment levels across the basin. The other components are still in development: The prototype of the “what-if” scenario builder tool is expected to launch in December 2025, with the full version planned for May 2026.

HydroFlame’s ability to capture compounding factors — drought before a fire, flooding afterward — and simulate their cascading effects on water systems is what makes it different from other tools, Rajib said. “Many traditional models treat each fire as a one-off,” he said. “HydroFlame looks at the bigger picture.”

Just as important, the tool is built for people who aren’t experts in satellite data.

“It’s a practical starting point for scenario planning,” said Kelly Luis, associate program manager for NASA’s water resources program and an aquatic ecosystem scientist at NASA’s Jet Propulsion Laboratory in Southern California. The tool’s “what-if” function, she explained, will let water managers, city planners, and other officials apply their local knowledge. For example, they might zero in on the rivers and streams most important to a city’s water supply. “That kind of insight is essential for building solutions that are both scientifically grounded and locally relevant.”

For watershed organizations or local and state agencies with limited staff and resources, that ease of use is crucial — saving time and effort while helping keep costs down.

“These groups need holistic ways to understand potential impacts of fires to their rivers and streams and plan, without always having to bring in someone from the outside,” said Amy Seaman, the executive director of the Montana Watershed Coordination Council. Seaman works with community watershed organizations across Montana and is also part of the project’s advisory group.

This effort is part of a broader NASA focus on understanding how fire reshapes water systems and what that means for American communities.

A real-world trial in Los Angeles

Rajib’s team put HydroFlame’s predictive capabilities to the test during the January 2025 wildfires in Los Angeles. As fires burned through the region, researchers ran real-time model simulations using NASA satellite data, tracking changes in vegetation, soil moisture, and burn severity almost as they happened. By the end of the month, the team had generated forecasts for mud and debris flows expected in February.

Those predictions turned out to be accurate. In early February, mudflow events struck the areas of Altadena and Sierra Madre in Los Angeles County, following the Eaton Fire. HydroFlame had been run specifically for that fire and flagged both neighborhoods as at risk, Rajib said.

“It wasn’t a formal, data-verified result because we didn’t have ground sensors in place,” Rajib said. “But it was a practical validation. The timing and severity of what we modeled lined up with what occurred.”

Rajib’s team is now working with NASA JPL, the University of California, Merced and Los Angeles County to formally test and expand the tool in the Los Angeles area. The team plans to begin collecting on-the-ground data no earlier than Friday, Sept. 26. That work will include installing stream sensors to measure sediment levels in the county’s streams during California’s rainy season and integrating those data into the tool — a step toward building an early-warning system.

HydroFlame invites those interested in the tool to share their ideas and feedback, and to get involved, through a web form available on the project’s Explore Tools webpage.

Help Map the Moon’s Molten Flows!

When asteroids hit the Moon, the impacts carve out craters and with enough energy and pressure, melt parts of the rocky surface. Often, the white hot, gooey melt (it’s like lava, except that it doesn’t erupt from underground) sloshes around the new crater and surrounding regions. The molten rock cools and hardens into vast rock features called impact melt flow deposits. These flow deposits are sculpture-like abstract art with beautiful lines and textures.

Now, scientists at the Lunar Melt citizen science project are asking for your help mapping these flows. You’ll be marking rocks, measuring the lengths of boulders, and outlining craters and melt deposits in images from NASA’s Lunar Reconnaissance Orbiter spacecraft.

Your contributions will help reveal how impact melt has changed the Moon’s surface, especially around Little Lowell Crater and Tycho Crater, and help scientists use impact melt flows to learn about the moon’s interior.

La NASA y la NOAA lanzan tres naves espaciales para cartografiar la influencia del Sol en el espacio

Read this press release in English here.

La NASA y la Administración Nacional Oceánica y Atmosférica (NOAA, por sus siglas en inglés) lanzaron el miércoles tres nuevas misiones para investigar la influencia del Sol en todo el sistema solar.

A las 7:30 a. m. EDT, un cohete Falcon 9 de SpaceX despegó del Complejo de Lanzamiento 39A del Centro Espacial Kennedy de la NASA en Florida, llevando a bordo las misiones Sonda de Cartografía y Aceleración Interestelar (IMAP, por su acrónimo en inglés) y el Observatorio Carruthers de la Geocorona, ambos de la NASA, y la nave espacial de Seguimiento de la Meteorología Espacial en el Punto de Lagrange 1 (SWFO-L1, por sus siglas en inglés) de la NOAA.

“Este exitoso lanzamiento mejora la preparación de nuestro país ante las condiciones meteorológicas espaciales para proteger mejor nuestros satélites, misiones interplanetarias y astronautas que viajan al espacio de los peligros de la meteorología espacial en todo el sistema solar”, afirmó el administrador interino de la NASA, Sean Duffy. “Esta información será fundamental a medida que nos preparamos para futuras misiones a la Luna y Marte con la intención de mantener a Estados Unidos a la vanguardia en el espacio”.

Estas misiones ayudarán a proteger de las duras condiciones de la meteorología espacial tanto a nuestra tecnología basada en tierra como a nuestros exploradores espaciales humanos y robóticos.

“Mientras Estados Unidos se prepara para enviar a seres humanos de vuelta a la Luna y más adelante a Marte, la NASA y la NOAA están proporcionando la guía definitiva de supervivencia interplanetaria para dar apoyo a este épico viaje de la humanidad”, afirmó Nicola Fox, administradora asociada de la Dirección de Misiones Científicas de la sede central de la NASA en Washington. “Nuestros descubrimientos científicos e innovaciones técnicas se incorporan directamente a nuestro plan de acción know-before-you-go (infórmate antes de ir) para garantizar una presencia humana bien preparada, segura y continua en otros mundos”.

Nueva ciencia para proteger a la sociedad

Cada misión investigará los diferentes efectos de la meteorología espacial y el viento solar, el cual es un flujo continuo de partículas emitidas por el Sol, desde su origen en nuestra estrella hasta el espacio interestelar.

“Estas tres misiones únicas nos ayudarán a conocer nuestro Sol y sus efectos sobre la Tierra mejor que nunca”, afirmó Joe Westlake, director de la División de Heliofísica en la sede central de la NASA. “Este conocimiento es fundamental, ya que la actividad solar afecta directamente a nuestra vida cotidiana, desde las redes eléctricas hasta el GPS. Estas misiones nos ayudarán a garantizar la seguridad y la resiliencia de nuestro mundo interconectado”.

La misión IMAP trazará los límites de la heliosfera, una burbuja inflada por el viento solar que protege nuestro sistema solar de los rayos cósmicos galácticos. Esta es una protección clave que contribuye a que nuestro planeta sea habitable. Además, la nave espacial tomará muestras y medirá las partículas del viento solar que fluyen hacia el exterior desde el Sol, así como las partículas energéticas que fluyen hacia el interior desde los límites de nuestro sistema solar y más allá.

“IMAP nos ayudará a comprender mejor cómo el entorno espacial puede perjudicarnos a nosotros y a nuestras tecnologías, y a descubrir la ciencia de nuestro vecindario solar”, afirmó David McComas, investigador principal de la misión IMAP en la Universidad de Princeton, en Nueva Jersey.

El Observatorio Carruthers de la Geocorona es la primera misión dedicada a medir los cambios en la capa más externa de nuestra atmósfera, la exosfera, la cual juega un papel importante en cómo la Tierra responde a la meteorología espacial. Al estudiar la geocorona —el brillo ultravioleta que emite la exosfera cuando la luz del sol la ilumina— la misión Carruthers revelará cómo la exosfera responde a las tormentas solares y cómo cambia con las estaciones. La misión se basa en el legado del primer instrumento que capturó imágenes de la geocorona, el cual viajó a la Luna a bordo de Apolo 16 y fue construido y diseñado por el científico, inventor, ingeniero y educador Dr. George Carruthers.

“La misión Carruthers nos mostrará cómo funciona la exosfera y nos ayudará a mejorar nuestra capacidad para predecir los efectos de la actividad solar aquí en la Tierra”, dijo Lara Waldrop, investigadora principal de la misión en la Universidad de Illinois en Urbana-Champaign.

La nave SWFO-L1 de la NOAA, la primera de su tipo, está diseñada para ser un observatorio de meteorología espacial operativo a tiempo completo. Al vigilar la actividad solar y las condiciones espaciales cerca de la Tierra las 24 horas del día, los 7 días de la semana, sin interrupciones ni obstrucciones, SWFO-L1 proporcionará pronósticos de meteorología espacial más rápidos y precisos que nunca.

“Se trata del primero de una nueva generación de observatorios de meteorología espacial de la NOAA dedicados a operaciones ininterrumpidas, que trabajarán para evitar lagunas en la continuidad. Las observaciones en tiempo real de SWFO-L1 proporcionarán a los operadores los datos fiables necesarios para emitir alertas tempranas, de modo que los responsables de la toma de decisiones puedan actuar con antelación para proteger las infraestructuras vitales, los intereses económicos y la seguridad nacional en la Tierra y en el espacio. Se trata de proteger a la sociedad contra los peligros de la meteorología espacial”, dijo Richard Ullman, subdirector de la Oficina de Observaciones de la Meteorología Espacial de la NOAA

Siguientes pasos

En las horas posteriores al lanzamiento, las tres naves espaciales se desplegaron desde el cohete con éxito y enviaron señales a la Tierra para confirmar que están activas y funcionando correctamente.

Durante los próximos meses, los satélites se dirigirán a su destino, un lugar situado entre la Tierra y el Sol, a unos 1,6 millones de kilómetros de la Tierra, denominado punto de Lagrange 1 (L1). Se espera que lleguen en enero y, una vez completadas las comprobaciones y calibraciones de sus instrumentos, comiencen sus misiones para comprender mejor la meteorología espacial y proteger a la humanidad.

David McComas, de la Universidad de Princeton, dirige la misión IMAP con un equipo internacional formado por 27 instituciones asociadas. El Laboratorio de Física Aplicada de la Universidad Johns Hopkins, ubicado en Laurel, Maryland, construyó la nave espacial y operará la misión.

La misión del Observatorio Carruthers de la Geocorona está dirigida por Lara Waldrop, de la Universidad de Illinois Urbana-Champaign. La ejecución de la misión está a cargo del Laboratorio de Ciencias Espaciales de la Universidad de California, Berkeley, que también diseñó y construyó los dos generadores de imágenes ultravioletas. BAE Systems diseñó y construyó la nave espacial Carruthers.

La División de Proyectos de Exploradores y Heliofísica de la NASA en el Centro de Vuelo Espacial Goddard de la NASA en Greenbelt, Maryland, gestiona las misiones IMAP y Observatorio Carruthers de la Geocorona para la Dirección de Misiones Científicas de la NASA.

La misión SWFO-L1 está gestionada por la NOAA y desarrollada en colaboración con el centro Goddard de la NASA y socios comerciales. El Programa de Servicios de Lanzamiento de la NASA, con sede en el centro Kennedy de la NASA, gestiona el servicio de lanzamiento de las misiones.
