Snippets from The Earth Observer’s Editor’s Corner
PACE-PAX
PACE–PAX had as its primary objective to gather data to validate measurements from NASA’s PACE mission. A secondary objective was validation of observations by the European Space Agency’s recently launched Earth Cloud, Aerosol, and Radiation Explorer (EarthCARE) mission. The operations spanned Southern and Central California and nearby coastal regions, logging 81 flight hours for the NASA ER-2, which operated out of NASA’s Armstrong Flight Research Center (AFRC) in Edwards, CA, and 60 hours for the Twin Otter aircraft, which was operated by the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) at the Naval Postgraduate School (Monterey, CA) out of Marina Municipal Airport in Marina, CA – see Photo.

The image shows the Twin Otter aircraft missing the approach at Marina Airport to check instrument performance on the aircraft against identical instrumentation on an airport control tower. Photo credit: NASA NASA’s ER-2 aircraft flies at an altitude of approximately 20 km, well above the troposphere. PACE–PAX researchers used the unique high-altitude vantage point to make observations of the atmosphere, ocean, and land surface in a similar manner to that of PACE. In so doing, they can verify the accuracy of data gathered by the satellite in orbit. Meanwhile, the Twin Otter flew at a much lower altitude in the atmosphere (~3 km). The instrumentation onboard the Twin Otter was used to sample and measure cloud droplet size, aerosol size, and the amount of light scattered or absorbed by the particles. These aircraft observations are the same atmospheric properties that PACE observes from its broader vantage point in polar orbit. In addition to the PACE and aircraft observations, the R/V Shearwater operated 15 day trips out of Santa Barbara, CA, gathering additional surface-based observations along with other vessels and floats.
Field campaigns, such as PACE–PAX, are designed to collect measurements at different scales and conditions for comparison to satellite observations. When it comes to doing this successfully, timing is everything. PACE–PAX observations were carefully coordinated so that the two aircraft were in flight and taking observations at the same time, so observations were being obtained at the surface (e.g., on the ship) as well as the satellite passing overhead. This takes a tremendous amount of effort on the part of the organizers.
BlueFlux
BlueFlux was set up to study the wetland ecosystems of South Florida. Wetland ecosystems represent the ever-changing line between land and sea, and are exceptionally vulnerable to climate disturbances, such as sea level rise and tropical cyclones. As these threats intensify, wetland ecology – and its role as a critical sink of CO2 – faces an uncertain future.
BlueFlux observations will contribute to the development of a new, remote-sensing data product called “Daily Flux Predictions for South Florida,” which will help research teams led by Ben Poulter [GSFC] explain and quantify the changing relationship between wetlands and atmospheric greenhouse gas concentrations (GHG). The goal is to refine global GHG budget analyses and provide regional stakeholders with information to evaluate how Florida’s wetlands are responding to natural and anthropogenic pressures in real time.
The “Daily Flux Predictions for South Florida” product will use retrievals of surface spectral reflectance captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA’s Aqua and Terra satellites to estimate the rate at which various gasses are exchanged between Earth’s surface and the atmosphere. Such flux measurements in coastal wetlands are historically limited on account of the relative inaccessibility of these ecosystems. To contribute to a more robust understanding of how Florida’s coastal ecology fits into the carbon cycle, BlueFlux conducted a series of airborne fieldwork deployments out of the Miami Homestead Air Reserve Base and the Miami Executive Airport in Miami-Dade County, which are adjacent to the eastern border of the Everglades National Park. The full study region – broadly referred to as South Florida – is narrowly defined by the wetland ecosystems that extend from Lake Okeechobee and its Northern estuaries to the saltwater marshland and mangrove forests along the state’s southernmost shore.
Flux measurements were made along each flight track using a payload known as the CARbon Airborne Flux Experiment (CARAFE) flying at between about 90 m and 3000 m. The researchers configured airborne observations, along with additional ground-based flux measurements, to match the spatial and temporal resolution of spectra collected by MODIS sensors, which produce surface reflectance retrievals at a 500 m daily resolution. Mirroring the scale of MODIS observations was necessary to both train the flux product’s underlying machine-learning algorithms and validate the accuracy of predictions made using satellite data alone. Data collected during BlueFlux fieldwork campaigns is available to the general public through NASA’s Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). The “Daily Flux Predictions for South Florida” data product will also be accessible through NASA’s ORNL DAAC by early 2025.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA logo In fiscal year 2023, NASA investments supported 66,208 jobs in the state of California, generated $18.5 billion in economic output and $1 billion in tax revenue to the state’s economy.
Overall, NASA generated an estimated $9.5 billion in federal, state, and local taxes throughout the United States.
NASA’s Armstrong Flight Research Center in Edwards, California is one of three NASA centers in the state that contributes to this economic achievement. The center supports critical research in sustainable flight, air mobility, and airborne science, reinforcing the region as a hub of aerospace innovation.
Most notably, NASA Armstrong plays a unique role in the Quesst mission and X-59 project, aimed at reducing the sonic booms into quieter “sonic thumps,” to change regulations impeding supersonic flight over land. Additionally, maturing key airframe technologies with the X-66 aircraft in the Sustainable Flight Demonstrator project which may influence the next generation single-aisle seat class airliner. The Center also supports the research of electric air taxis and drones to operate safely in the national airspace as well as supporting science aircraft for NASA’s Earth Science Mission.
NASA’s Moon to Mars campaign generated 16,129 jobs and $4.7 billion in economic output in California. Collaborations with contractors like Boeing and Lockheed Martin further extended these benefits by creating thousands of high-skilled jobs in the Antelope Valley and across the state.
NASA also fosters partnerships with educational institutions across the state, investing $39.5 million in universities to cultivate the next generation of aerospace innovators. These investments bring STEM opportunities to local communities and prepare students for careers in cutting-edge industries – adding to the agency’s most valuable asset, its workforce.
NASA embraces the challenges of exploring the unknown and making the impossible possible as we continue our global leadership in science, human spaceflight, aerospace innovation, and technology development, and support the U.S. economy and benefit all.

Kennedy Space Center Director Janet Petro speaks in March 2022 during the annual State of NASA event at the Florida spaceport. NASA/Kim Shiflett America is returning to the Moon with our sights set on Mars, and NASA is leading the way. Along with our industry and international partners, we’re advancing scientific research, inspiring the next generation of explorers, and ensuring reliable and continuous access to space for our nation.
NASA’s Economic Impact Report for fiscal year (FY) 2023 highlights the nation’s strong return on its investment in NASA. Our missions help unveil the secrets of the universe and our home planet while also benefitting the taxpayers, communities, and industries across the country.
Here at the agency’s Kennedy Space Center in Florida, we are on track for another record-setting year of launches from our Space Coast. Recent NASA missions will tell us more about Earth’s weather and climate, explore Jupiter’s moon Europa for the ingredients of life, and enable more innovative research on the International Space Station. We’re also busy building the Artemis rockets, spacecraft, and technologies that will allow our astronauts to live and work on the Moon.
While exploring the universe for the benefit of all, NASA is also supporting the U.S. economy. During FY23, an investment of less than one-half of 1% of the federal budget, the agency generated $76 billion in total economic output nationwide.
In Florida alone, NASA activities in FY2023 supported 35,685 jobs in the state and $8.2 billion in economic output, resulting in an additional $286.6 million in state tax revenue. NASA Kennedy’s unique facilities, proven technical capabilities, and master plan enable nearly 250 partnerships with 100 private-sector partners. And the dedication and commitment of our workforce means that our spaceport remains the world’s leader in space science, human exploration, and technology development.
As we look toward a future of more exploration and discovery, I invite you to learn more about the impacts that NASA missions may have had in your life. The agency’s technology transfer initiatives transition NASA innovations into private hands, where real impacts are made. And NASA’s STEM engagements encourage research and the study of science, technology, engineering, and math at all ages.
And, of course, I hope you will learn more about the exciting work we’re doing at Earth’s premier spaceport by visiting:
