ESPO solves problems before you know you have them. If you are missing a canister of liquid nitrogen, got locked out of your rental car, or need clearance for a South Korean military base, you want ESPO in your corner.

What is ESPO?

While the Earth Science Project Office (ESPO) does many things, one of the team’s primary responsibilities is providing project management for many of the largest and most complex airborne campaigns across NASA’s Earth Science Division.

Some of these missions are domestic, such as the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE). S-MODE deployed three separate field campaigns from 2021-2023, using planes, drones, marine robotics, and research vessels to study ocean eddies and sub-surface dynamics. NASA Ames Research Center, located in Northern California, served as S-MODE’s control center and the base for two of the three deployed aircraft.

ESPO also provides project management for many international missions, such as the Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ), which deployed in January, 2024 out of South Korea, Thailand, and the Philippines. The campaign used satellites, aircraft, and ground-based sensors to study air quality across Asia, as part of a global effort to better understand the factors that contribute to air quality.

Despite the critical nature of ESPO’s work, they’ll be the first to tell you that their goal is to remain behind the scenes. “Our mission statement is essentially to let the scientists concentrate on science,” said Erin Czech, Assistant Branch Chief of ESPO. “Our team’s job is to stay in the background. We don’t really advertise all the things we do, the pieces we put together, the crises we solve, because we don’t want folks to have to be in the weeds with us. We’ll take care of it.”

Making the invisible, visible: What does this look like in practice?

Before a deployment:

Project management for major airborne campaigns begins long before a deployment. The team begins by helping establish a mission framework, such as getting a budget in place, settling grants and funding with partner universities and agencies, and performing site visits.

“We are not scientists,” Czech said, “it’s the job of the Principal Investigator to mission plan. Our job is to evaluate risk, set up contingency plans, and help make sure all the different groups are talking to each other. We work with world-class scientists, who are going to come up with an awesome plan; we just want to do whatever we need to in order to support them.”

As the deployment date draws closer, the team nails down logistics: deciding how and where to ship equipment, reserving hotel blocks for researchers, acquiring diplomatic clearances, running planning meetings between agencies, and so much more.

This process is particularly complicated for multi-site, international missions like ASIA-AQ, which required multiple visits to each country before the actual deployment. “We looked at many locations in each country on the first scouting trip, to help figure out deployment sites,” said Jhony Zavaleta, Deputy Director for ESPO and Project Manager for ASIA-AQ. “The second scouting trip was to evaluate modifications promised during the first trip, such as upgrades to infrastructure, and to figure out hotels, transit options, specific facilities for mission operations, that sort of thing.”

According to Zavaleta, another purpose of these advance trips was to put pieces in place with partner organizations  – such as civilian aviation authorities, foreign science ministries, or military operations – so that when NASA officially requested diplomatic clearance to run the airborne campaigns, the groundwork had already been laid.

Then it’s go time. 

During the deployment:

As the deployment gets underway, ESPO keeps the flurry of activity running as smoothly as possible.

“During a deployment, you’re working all day every day,” said Czech, who is also the Project Manager for S-MODE. “But really that’s the whole mission team. When you’re on a NASA project, the whole team is incredibly dedicated and working like crazy, because everybody’s on the same page to make the most out of this investment, and take advantage of any kind of science opportunity that presents itself day to day.”

For Zavaleta, day-to-day operations meant escorting personnel onto military bases, tracking down liquid nitrogen, coordinating media days with local news outlets, setting up satellite communications, arranging transportation between sites, and preparing the next location. “I was on the ESPO advance team, which would set up one location, overlap with the ESPO site management team for about a week, then head to the next,” Zavaleta recalled. “Our teams would leapfrog; we were always managing site logistics, but also always preparing and setting up for the next spot.”

Beyond the day-to-day operations, ESPO also steps in when major issues arise. According to Czech, they can usually expect one or two big wrenches to come up for any major mission.

For S-MODE, the first wrench came in the form of a global pandemic. “The original deployment was set for April, 2020,” Czech said. “Everything was shutting down, and we had just set everything up: ship, aircraft, everything. In fact, we set everything up two more times before we ultimately got to do our first deployment, in October of 2021.”

The second major wrench happened when four months before the actual launch, the research vessel the mission was planned around backed out. From there, Czech said it was a mad scramble to find a suitable replacement vessel that was already on the West Coast, and to build out the on-board infrastructure to meet the mission requirements.

“The key is just to always be on the lookout for issues, keep agile, and don’t get too frustrated if things don’t go your way,” Czech said. “It is what it is. Some major issue comes up on every big mission: you’ve just got to figure out how to deal with it, then move on.”

After the deployment:

After a field deployment is finished, there are still years of work to do – for the scientists and for ESPO.

The final S-MODE field deployment concluded in Spring of 2023. While the science team has been processing data and analyzing results, ESPO’s role has been to organize annual science team meetings, track publications tied to the mission, and help compile a final report to be presented in Washington DC when the mission officially wraps in May of 2025.

For ASIA-AQ, whose deployment wrapped up in March of 2024, ESPO’s first task was getting all equipment and personnel back to their respective home bases. Next up, Zavaleta and his team are coordinating a science team meeting in Malaysia in January of 2025, and supporting the scientists as they put together a preliminary research report for later that spring.

Knowledge and Expertise

While logistical skills and communication brokering are important pieces of ESPO’s role, knowledge may be the group’s most important asset. “In many ways, our value to NASA lies in the fact that we’ve been doing this a long time,” Czech said. “Our first mission was in 1987, and we’ve run over 60 campaigns since then; we have a lot of institutional knowledge that gets passed down, and a lot of experience between our team members. That expertise is a large part of our value to the agency.”

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s AVIRIS-3 airborne imaging spectrometer was used to map a wildfire near Cas-tleberry, Alabama, on March 19. Within minutes, the image was transmitted to firefighters on the ground, who used it to contain the blaze. NASA/JPL-Caltech, NASA Earth Observatory The map visualizes three wavelengths of infrared light, which are invisible to the human eye. Orange and red areas show cooler-burning areas, while yellow indicates the most intense flames. Burned areas show up as dark red or brown.NASA/JPL-Caltech, NASA Earth Observatory Data from the AVIRIS-3 sensor was recently used to create detailed fire maps in minutes, enabling firefighters in Alabama to limit the spread of wildfires and save buildings.
      A NASA sensor recently brought a new approach to battling wildfire, providing real-time data that helped firefighters in the field contain a blaze in Alabama. Called AVIRIS-3, which is short for Airborne Visible Infrared Imaging Spectrometer 3, the instrument detected a 120-acre fire on March 19 that had not yet been reported to officials.
      As AVIRIS-3 flew aboard a King Air B200 research plane over the fire about 3 miles (5 kilometers) east of Castleberry, Alabama, a scientist on the plane analyzed the data in real time and identified where the blaze was burning most intensely. The information was then sent via satellite internet to fire officials and researchers on the ground, who distributed images showing the fire’s perimeter to firefighters’ phones in the field.
      All told, the process from detection during the flyover to alert on handheld devices took a few minutes. In addition to pinpointing the location and extent of the fire, the data showed firefighters its perimeter, helping them gauge whether it was likely to spread and decide where to add personnel and equipment.
      As firefighters worked to prevent a wildfire near Perdido, Alabama, from reaching nearby buildings, they saw in an infrared fire map from NASA’s AVIRIS-3 sensor that showed the fire’s hot spot was inside its perimeter. With that intelligence, they shifted some resources to fires in nearby Mount Vernon.NASA/JPL-Caltech, NASA Earth Observatory “This is very agile science,” said Robert Green, the AVIRIS program’s principal investigator and a senior research scientist at NASA’s Jet Propulsion Laboratory in Southern California, noting AVIRIS-3 mapped the burn scar left near JPL by the Eaton Fire in January.
      Observing the ground from about 9,000 feet (3,000 meters) in altitude, AVIRIS-3 flew aboard several test flights over Alabama, Mississippi, Florida, and Texas for a NASA 2025 FireSense Airborne Campaign. Researchers flew in the second half of March to prepare for prescribed burn experiments that took place in the Geneva State Forest in Alabama on March 28 and at Fort Stewart-Hunter Army Airfield in Georgia from April 14 to 20. During the March span, the AVIRIS-3 team mapped at least 13 wildfires and prescribed burns, as well as dozens of small hot spots (places where heat is especially intense) — all in real time.
      At one of the Mount Vernon, Alabama, fires, firefighters used AVIRIS-3 maps to determine where to establish fire breaks beyond the northwestern end of the fire. They ultimately cut the blaze off within about 100 feet (30 meters) of four buildings.NASA/JPL-Caltech, NASA Earth Observatory Data from imaging spectrometers like AVIRIS-3 typically takes days or weeks to be processed into highly detailed, multilayer image products used for research. By simplifying the calibration algorithms, researchers were able to process data on a computer aboard the plane in a fraction of the time it otherwise would have taken. Airborne satellite internet connectivity enabled the images to be distributed almost immediately, while the plane was still in flight, rather than after it landed.
      The AVIRIS team generated its first real-time products during a February campaign covering parts of Panama and Costa Rica, and they have continued to improve the process, automating the mapping steps aboard the plane.
      ‘Fan Favorite’
      The AVIRIS-3 sensor belongs to a line of imaging spectrometers built at JPL since 1986. The instruments have been used to study a wide range of phenomena — including fire — by measuring sunlight reflecting from the planet’s surface.
      During the March flights, researchers created three types of maps. One, called the Fire Quicklook, combines brightness measurements at three wavelengths of infrared light, which is invisible to the human eye, to identify the relative intensity of burning. Orange and red areas on the Fire Quicklook map show cooler-burning areas, while yellow indicates the most intense flames. Previously burned areas show up as dark red or brown.
      Another map type, the Fire 2400 nm Quicklook, looks solely at infrared light at a wavelength of 2,400 nanometers. The images are particularly useful for seeing hot spots and the perimeters of fires, which show brightly against a red background.
      A third type of map, called just Quicklook, shows burned areas and smoke.
      The Fire 2400 nm Quicklook was the “fan favorite” among the fire crews, said Ethan Barrett, fire analyst for the Forest Protection Division of the Alabama Forestry Commission. Seeing the outline of a wildfire from above helped Alabama Forestry Commission firefighters determine where to send bulldozers to stop the spread. 
      Additionally, FireSense personnel analyzed the AVIRIS-3 imagery to create digitized perimeters of the fires. This provided firefighters fast, comprehensive intelligence of the situation on the ground.
      That’s what happened with the Castleberry Fire. Having a clear picture of where it was burning most intensely enabled firefighters to focus on where they could make a difference — on the northeastern edge. 
      Then, two days after identifying Castleberry Fire hot spots, the sensor spotted a fire about 4 miles (2.5 kilometers) southwest of Perdido, Alabama. As forestry officials worked to prevent flames from reaching six nearby buildings, they noticed that the fire’s main hot spot was inside the perimeter and contained. With that intelligence, they decided to shift some resources to fires 25 miles (40 kilometers) away near Mount Vernon, Alabama.
      To combat one of the Mount Vernon fires, crews used AVIRIS-3 maps to determine where to establish fire breaks beyond the northwestern end of the fire. They ultimately cut the blaze off within about 100 feet (30 meters) of four buildings. 
      “Fire moves a lot faster than a bulldozer, so we have to try to get around it before it overtakes us. These maps show us the hot spots,” Barrett said. “When I get out of the truck, I can say, ‘OK, here’s the perimeter.’ That puts me light-years ahead.”
      AVIRIS and the Firesense Airborne Campaign are part of NASA’s work to leverage its expertise to combat wildfires using solutions including airborne technologies. The agency also recently demonstrated a prototype from its Advanced Capabilities for Emergency Response Operations project that will provide reliable airspace management for drones and other aircraft operating in the air above wildfires.

      Researchers utilizing publicly available Synthetic Aperture Radar (SAR) data from Capella Space and Umbra have uncovered significant hidden structures within and beneath the CFR Pyramid on the Giza Plateau. The study reveals five distinct "Zed" structures located above what was previously believed to be the pharaoh’s burial chamber, resembling similar formations found in the Khufu Pyramid. These structures are connected by geometric pathways, with additional secondary formations identified through satellite imaging. 
      Source and credit images: The Reese report / The Kafre Research Project.
      Most notably, eight vertically aligned cylindrical structures, arranged in two parallel rows from north to south, extend 648 meters underground. These formations merge into two massive cubic structures, each approximately 80 meters per side. Tomographical analysis indicates that the cylindrical structures function as hollow wells surrounded by descending spiral pathways. 
      Further research suggests that these subterranean formations are not limited to the CFR Pyramid but extend beneath the Khufu and Menkaure pyramids as well, reaching depths of approximately two kilometers. The study marks a groundbreaking advancement in the understanding of the Giza Plateau’s underground complexity, 
      The discoveries surrounding the CFR Pyramid represent just the tip of a vast and complex structure beneath the Giza Plateau.If confirmed, this discovery could challenge mainstream Egyptology’s belief that the pyramids were simply royal tombs.

      NASA, ESA, CSA, and Joseph Olmsted (STScI) An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric factors, and cannot be explained by clouds alone.
      Using NASA’s James Webb Space Telescope to monitor a broad spectrum of infrared light emitted over two full rotation periods by SIMP 0136, the team was able to detect variations in cloud layers, temperature, and carbon chemistry that were previously hidden from view.
      The results provide crucial insight into the three-dimensional complexity of gas giant atmospheres within and beyond our solar system. Detailed characterization of objects like these is essential preparation for direct imaging of exoplanets, planets outside our solar system, with NASA’s Nancy Grace Roman Space Telescope, which is scheduled to begin operations in 2027.
      Rapidly Rotating, Free-Floating
      SIMP 0136 is a rapidly rotating, free-floating object roughly 13 times the mass of Jupiter, located in the Milky Way just 20 light-years from Earth. Although it is not classified as a gas giant exoplanet — it doesn’t orbit a star and may instead be a brown dwarf — SIMP 0136 is an ideal target for exo-meteorology: It is the brightest object of its kind in the northern sky. Because it is isolated, it can be observed with no fear of light contamination or variability caused by a host star. And its short rotation period of just 2.4 hours makes it possible to survey very efficiently.
      Prior to the Webb observations, SIMP 0136 had been studied extensively using ground-based observatories and NASA’s Hubble and Spitzer space telescopes.
      “We already knew that it varies in brightness, and we were confident that there are patchy cloud layers that rotate in and out of view and evolve over time,” explained Allison McCarthy, doctoral student at Boston University and lead author on a study published today in The Astrophysical Journal Letters. “We also thought there could be temperature variations, chemical reactions, and possibly some effects of auroral activity affecting the brightness, but we weren’t sure.”
      To figure it out, the team needed Webb’s ability to measure very precise changes in brightness over a broad range of wavelengths.
      Graphic A: Isolated Planetary-Mass Object SIMP 0136 (Artist’s Concept)
      This artist’s concept shows what the isolated planetary-mass object SIMP 0136 could look like based on recent observations from NASA’s James Webb Space Telescope and previous observations from Hubble, Spitzer, and numerous ground-based telescopes. Researchers used Webb’s NIRSpec (Near-Infrared Spectrograph) and MIRI (Mid-Infrared Instrument) to measure subtle changes in the brightness of infrared light as the object completed two 2.4-hour rotations. By analyzing the change in brightness of different wavelengths over time, they were able to detect variability in cloud cover at different depths, temperature variations in the upper atmosphere, and changes in carbon chemistry as different sides of the object rotated in and out of view. This illustration is based on Webb’s spectroscopic observations. Webb has not captured a direct image of the object. NASA, ESA, CSA, and Joseph Olmsted (STScI) Charting Thousands of Infrared Rainbows
      Using NIRSpec (Near-Infrared Spectrograph), Webb captured thousands of individual 0.6- to 5.3-micron spectra — one every 1.8 seconds over more than three hours as the object completed one full rotation. This was immediately followed by an observation with MIRI (Mid-Infrared Instrument), which collected hundreds of spectroscopic measurements of 5- to 14-micron light — one every 19.2 seconds, over another rotation.
      The result was hundreds of detailed light curves, each showing the change in brightness of a very precise wavelength (color) as different sides of the object rotated into view.
      “To see the full spectrum of this object change over the course of minutes was incredible,” said principal investigator Johanna Vos, from Trinity College Dublin. “Until now, we only had a little slice of the near-infrared spectrum from Hubble, and a few brightness measurements from Spitzer.”
      The team noticed almost immediately that there were several distinct light-curve shapes. At any given time, some wavelengths were growing brighter, while others were becoming dimmer or not changing much at all. A number of different factors must be affecting the brightness variations.
      “Imagine watching Earth from far away. If you were to look at each color separately, you would see different patterns that tell you something about its surface and atmosphere, even if you couldn’t make out the individual features,” explained co-author Philip Muirhead, also from Boston University. “Blue would increase as oceans rotate into view. Changes in brown and green would tell you something about soil and vegetation.”
      Graphic B: Isolated Planetary-Mass Object SIMP 0136 (NIRSpec Light Curves)
      These light curves show the change in brightness of three different sets of wavelengths (colors) of near-infrared light coming from the isolated planetary-mass object SIMP 0136 as it rotated. The light was captured by Webb’s NIRSpec (Near-Infrared Spectrograph), which collected a total of 5,726 spectra — one every 1.8 seconds — over the course of about 3 hours on July 23, 2023. The variations in brightness are thought to be related to different atmospheric features — deep clouds composed of iron particles, higher clouds made of tiny grains of silicate minerals, and high-altitude hot and cold spots — rotating in and out of view. The diagram at the right illustrates the possible structure of SIMP 0136’s atmosphere, with the colored arrows representing the same wavelengths of light shown in the light curves. Thick arrows represent more (brighter) light; thin arrows represent less (dimmer) light. NASA, ESA, CSA, and Joseph Olmsted (STScI) Patchy Clouds, Hot Spots, and Carbon Chemistry
      To figure out what could be causing the variability on SIMP 0136, the team used atmospheric models to show where in the atmosphere each wavelength of light was originating.
      “Different wavelengths provide information about different depths in the atmosphere,” explained McCarthy. “We started to realize that the wavelengths that had the most similar light-curve shapes also probed the same depths, which reinforced this idea that they must be caused by the same mechanism.”
      One group of wavelengths, for example, originates deep in the atmosphere where there could be patchy clouds made of iron particles. A second group comes from higher clouds thought to be made of tiny grains of silicate minerals. The variations in both of these light curves are related to patchiness of the cloud layers.
      A third group of wavelengths originates at very high altitude, far above the clouds, and seems to track temperature. Bright “hot spots” could be related to auroras that were previously detected at radio wavelengths, or to upwelling of hot gas from deeper in the atmosphere.
      Some of the light curves cannot be explained by either clouds or temperature, but instead show variations related to atmospheric carbon chemistry. There could be pockets of carbon monoxide and carbon dioxide rotating in and out of view, or chemical reactions causing the atmosphere to change over time.
      “We haven’t really figured out the chemistry part of the puzzle yet,” said Vos. “But these results are really exciting because they are showing us that the abundances of molecules like methane and carbon dioxide could change from place to place and over time. If we are looking at an exoplanet and can get only one measurement, we need to consider that it might not be representative of the entire planet.”
      This research was conducted as part of Webb’s General Observer Program 3548.
      The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
