Summary of the 2024 NASA LCLUC Science Team Meeting

Introduction

The 2024 NASA Land-Cover and Land-Use Change (LCLUC) Science Team Meeting (STM) took place from April 2–4, 2024 at the Marriott Washingtonian Center in Gaithersburg, MD. During the meeting, 75 people attended in-person. Represented among the attendees were LCLUC project investigators and collaborators, NASA Headquarters (HQ) program managers, and university researchers and students – see Photo.

LCLUC is an interdisciplinary scientific program within NASA’s Earth Science program that aims to develop the capability for periodic global inventories of land use and land cover from space. The program’s goal is to develop the scientific understanding and models necessary to simulate the processes taking place and to evaluate the consequences of observed and predicted changes.

The LCLUC program’s focus is divided into three areas – impacts, monitoring, and synthesis. Each category constitutes about one-third of the program’s content. The LCLUC program is part of the Carbon Cycle and Ecosystems research area, alongside other programs, such as Terrestrial Ecosystems, Ocean Biology and Biogeochemistry, and Biodiversity.

Within NASA’s Earth Science Division (ESD), the LCLUC program collaborates with the Earth Science Technology Office (ESTO), the Earth Action Program element on Agriculture, and data initiatives, such as Harmonized Landsat Sentinel-2 (HLS), Observational Products for End-Users from Remote Sensing Analysis (OPERA), and the Commercial SmallSat Data Acquisition (CSDA) program. Externally, the program engages the U.S. Global Climate Research Program (USGCRP), U.S. Geological Survey (USGS), the U.S. Department of Agriculture (USDA), and the U.S. Forest Service (USFS). Internationally, the program collaborates with Global Observations of Forest Cover and Land-use Dynamics (GOFC-GOLD), the Group on Earth Observations (GEO), particularly Group on Earth Observations Global Agricultural Monitoring (GEOGLAM), the Global Land Program (GLP), as well as regional initiatives – e.g., the South and Southeast Asia Regional Initiative (SARI), and space agencies, including the European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), Geo-Informatics and Space Technology Development Agency (GISTDA)–Thailand, Vietnam National Space Center (VNSC), and the Indian Space Research Organisation (ISRO).

Principal Investigators (PIs) who participate in LCLUC are required to provide free and open access to their data and products via their metadata pages, aligning with NASA’s Transform to Open Science (TOPS) initiative. The program organizes at least one international regional workshop and one domestic ST meeting each year to share LCLUC science and foster global collaborations, contributing to regional capacity-building as an added value. Additionally, the program hosts regular webinars led by PIs on topics such as agriculture, urban areas, land-use changes in conflict zones, and natural disaster hotspots (i.e., fires, droughts, and floods). Garik Gutman [NASA HQ—LCLUC Program Manager] presented updates on LCLUC research publications, journal special issues, and upcoming international meetings.

The remainder of this article summarizes the highlights of the 2024 LCLUC STM. The content is organized chronologically, with a section devoted to describing each day of the meeting and descriptive headers throughout. The full presentations from this meeting are available on the LCLUC meeting website.

SARI Update and Related Projects

Krishna Vadrevu [NASA’s Marshall Space Flight Center] gave a comprehensive update on SARI, a regional initiative under the LCLUC program that addresses the critical needs of the South/Southeast Asia region by integrating remote sensing, natural sciences, engineering, and social sciences. His presentation covered the initiative’s background, various funded research projects, and their outputs. The diverse SARI projects include studies on forest degradation, agricultural transitions, food security, urbanization, and their environmental impacts. SARI has supported 35 research projects, engaging more than 400 scientists and over 200 institutions that result in significant scientific contributions, including nearly 450 publications, 16 special journal issues, and five books with two additional books pending publication. Vadrevu emphasized the importance of sustainable land use policies informed by LCLUC research and provided details on upcoming meetings. He concluded with information on three ongoing projects funded under the SARI synthesis solicitation – one in South Asia and two in Southeast Asia. Summaries of these projects are highlighted below.

David Skole [Michigan State University (MSU)] leads the SARI synthesis project that spans South Asian countries, with an emphasis on tree-based systems, particularly Trees Outside Forests (TOF). The primary objective is to synthesize existing research to better understand the patterns, drivers, and impacts of TOF on carbon emissions and removals and their role in supporting rural livelihoods. This research is crucial for informing climate change policy, particularly in the context of nature-based solutions and pathways to achieve net-zero emissions. The project combines empirical data with process-based research and policy models to support the development of sustainable landscapes. By integrating biophysical and socioeconomic data, the project team members aim to provide robust, evidence-based contributions to climate mitigation and adaptation strategies, ultimately guiding regional policy decisions.

Son Nghiem [NASA/Jet Propulsion Laboratory] discussed the interrelated dynamics of LCLUC and demographic changes in Southeast Asia under various developmental pressures and climate change. Nghiem explained that the study explores how these factors interact along the rural-to-urban continuum across regions in Cambodia, the Lao People’s Democratic Republic (Laos), Thailand, Vietnam, Malaysia, and parts of Indonesia. In rapidly urbanizing and agriculturally transitioning areas, physical and human feedback processes are becoming non-stationary, leading to unpredictable impacts that challenge traditional policymaking. The study aims to capture both physical patterns (e.g., land-use) and human (socioeconomic) fabrics, integrating these within a framework to assess whether the statistical properties of the time series measured during this study remain constant or change with time.

Peilei Fan [Tufts University] presented the project, “Decoding Land Transitions Across the Urban-Rural Continuums (URC): A Synthesis Study of Patterns, Drivers, and Socio-Environmental Impacts in Southeast Asia.” The project aims to synthesize knowledge through an interdisciplinary approach. It focuses on URCs in 19 cities across eight Southeast Asian countries. It investigates how global urban hierarchies, URC connectivity, and local policies influence land-use change and related ecosystem impacts. By integrating remote-sensing data with climate and ecological models and socioeconomic analysis, the project seeks to advance theoretical understanding of land transitions and provide valuable insights for both scientific research and policymaking.

Poster sessions

Following the presentations, participants gave lightning talks linked to 17 posters, which highlighted recent results from ongoing LCLUC projects and LCLUC-related research from the Future Investigators in NASA Earth and Space Science and Technology (FINESST) and the Inter-Disciplinary Research in Earth Science (IDS) programs. A reception followed. PDF versions of the posters can be accessed on the meeting website.

Ariane DeBremond [UMD] focused on the Global Land Programme (GLP), which is a comprehensive, global initiative dedicated to understanding and addressing changes in land systems and their implications for sustainability and justice. DeBremond described the program, which coordinates research on land use, land management, and land cover changes,. She emphasized land systems as social-ecological systems and fostering interdisciplinary collaboration to develop solutions for global challenges. The research agenda includes descriptive, normative, and transformative aspects, aimed at characterizing land systems, identifying causes and impacts of changes, and creating pathways for sustainability transformations. GLP also emphasizes the need for new remote-sensing data, improved generalizability, and addressing geographic biases in land system science. Recent program activities include developing a new science plan, identifying emerging themes, and organizing open science meetings. DeBremond ended by announcing that the next GLP meeting is scheduled for November 2024 in Oaxaca, Mexico.

David Skole outlined the efforts of the Global Observations of Forest and Land Cover Dynamics (GOFC–GOLD) Land Implementation Team (LC–IT) in advancing methods and tools for global land cover measurements and monitoring. The LC–IT is primarily focused on developing and evaluating space-borne and in-situ observation techniques to support global change research, forest inventories, and international policy. Skole highlighted the importance of regional networks in coordinating the use of Earth Observation (EO) data, facilitating capacity building, and addressing regional concerns through workshops and partnerships. He also discussed the changing role of EO in responding to climate change and sustainability challenges, emphasizing the need for high-integrity carbon finance and the integration of new data and technologies to support nature-based solutions. He concluded with insights into the BeZero Carbon Rating system, which evaluates carbon efficacy across various projects worldwide and highlights the need for reliable ratings to ensure the credibility of carbon markets.

David Roy [MSU] detailed the work of the GOFC-GOLD Fire Implementation Team, which focuses on improving the accuracy and utility of satellite-based fire monitoring. The team is working to enhance global fire observation requirements, particularly for small fires and those with low Fire Radiative Power, which are often underrepresented in current datasets. Roy emphasized the need for continuous development and validation of satellite-derived fire products, including a robust quality assurance framework. The team advocates for standardized methods to validate fire data and harmonize information from various satellite missions to create a more comprehensive global fire record. Roy also highlighted the need for new satellite missions with advanced fire detection capabilities and the use of machine learning to improve fire modeling and data accessibility to provide more accurate and actionable data for global change research and fire management.

Alexandra Tyukavina [UMD] presented on Land Product Validation (LPV) subgroup of the Committee on Earth Observation Satellites (CEOS) Working Group on Calibration and Validation (WGCV). The LPV is focused on updating land cover validation guidelines, incorporating new literature and data from the past 20 years. Tyukavina emphasized the need for rigorous accuracy assessment in land cover studies, highlighting the need to improve methods and reporting as well as accuracy. She also discussed the outcomes of a NASA-sponsored joint cropland validation workshop co-hosted by CEOS and GEOGLAM, which aimed to set minimum requirements for cropland validation and develop community guidelines. Tyukavina concluded her presentation with a call for reviewers to assist in updating these guidelines.

LCLUC Program Crosswalks

The Crosswalks, a LCLUC program, featured six presentations. Frederick Policelli [GSFC] presented on the CSDA program, which supports the ESD by acquiring and utilizing commercial, small-satellite data to enhance Earth science research. Launched as a pilot in November 2017, the program became a sustained effort in 2020, transitioning from Blanket Purchase Agreements to Indefinite-Delivery, Indefinite-Quantity contracts for better data management. The CSDA also introduced a tiered End User License Agreement for data usage and focuses on long-term data preservation and broad access. Policelli described how program participants collaborate with U.S. government agencies and international partners, adhering to the 2003 U.S. Commercial Remote Sensing Policy. He discussed recent developments, which include onboarding new commercial data vendors and expanding the program’s capabilities.

Jacqueline Le Moigne [ESTO] provided details on NASA’s Earth Science Technology Office’s (ESTO), Advanced Information Systems Technology (AIST) program and its development of Earth System Digital Twins (ESDT). She explained that ESDTs are intended to be dynamic, interactive systems that replicate the Earth’s past and current states, forecast future states, and assess hypothetical scenarios. They should integrate continuous data from diverse sources, utilize advanced computational and visualization capabilities, and rely heavily on machine learning for data fusion, super-resolution, and causal reasoning. Le Moigne added that ESDTs enhance our understanding of Earth systems, their interactions, and applications, particularly in the context of climate change. She highlighted various use cases (e.g., wildfires, ocean carbon processes, the water cycle, and coastal zones) demonstrating the potential of ESDTs to support decision-making and policy planning.

Roger Pielke [University of Colorado, Boulder] discussed the critical need to incorporate land-use data into weather forecasts and climate models to improve understanding of and address climate change. He emphasized the distinction between weather and climate, explaining that climate is dynamic and influenced by both natural and human factors. Pielke critiqued the focus of the approach of the Intergovernmental Panel on Climate Change (IPCC) on carbon dioxide (CO2) emissions as the primary driver of climate change, arguing that LCLUC should be considered as an equally important climate forcing. He illustrated how changes in land cover, such as in Florida and the Great Plains, can significantly impact local and regional climate, sometimes rivaling the effects of CO2. Pielke called for integrating land-use data into climate models across all scales, suggesting that NASA’s programs could lead in this effort to enhance climate forecasting and policymaking.

Brad Doorn [NASA HQ—Program Manager, NASA’s Earth Action Agriculture Program] presented an overview of the program’s status and strategic direction. He emphasized the importance of partnerships, particularly with the USDA, in advancing initiatives like Climate Smart Agriculture. NASA’s role in global food security and supply chain monitoring was highlighted through the activities of NASA’s Harvest and Acres, agriculture and food security consortia, both of which enable collaborative research to codevelop data-driven products and services and enhance predictive models to meet end-user needs. Doorn stressed the need for strong collaborations with the private sector, non-governmental organizations, and other space agencies to accelerate the development of agricultural solutions. He also highlighted the significance of integrating NASA’s capabilities in weather, water, and crop monitoring systems to provide comprehensive tools for stakeholders. Doorn explained that the program aims to bridge gaps between NASA’s observations and practical applications in agriculture, leveraging tools, such as the Global Crop Monitor, and integrating predictive capabilities for improved future planning.   

Rachel Paseka [NASA HQ] presented on NASA’s open science funding opportunities with a focus on the ROSES F.7 element, which supports widely used open-source software tools, frameworks, and libraries within the NASA science community. She described the program, which offers two types of awards: Foundational Awards for projects that impact multiple divisions and Sustainment Awards for those affecting one or more divisions of the Science Mission Directorate. Foundational Awards are cooperative agreements lasting up to five years. Sustainment Awards can be grants or cooperative agreements lasting up to three years. Paseka also emphasized the importance of open science, highlighting various tools, data challenges, and collaborative efforts, including artificial intelligence (AI) models for tasks (e.g., flood detection and burn scar mapping). She concluded with an introduction of the Science Explorer (SciX) digital library and the Science Discovery Engine, both of which facilitate access to NASA’s open science data and research.

He highlighted key SEDAC datasets (e.g., LCLUC and Urban and Settlements Datasets) and their use in analyses. SEDAC data and services are accessible via tools, such as Global Forest Watch and Google Earth Engine. de Sherbinin also covered recent research citations, the impact of studies on biodiversity and urban changes, and SEDAC’s contributions to open science and training initiatives. He also emphasized the importance of integrating remote sensing data with social and health sciences for comprehensive environmental analysis.

DAY THREE

The third day of the meeting focused on satellite missions and data product updates and a LCLUC program feedback session on emerging science directions.

Landsat Mission Updates

Chris Neigh [GSFC—Landsat 9 Project Scientist] provided an overview of the status of the current Landsat missions that are in orbit (L7, L8, and L9]. He reported that all L9 Level-1 requirements have now been met and exceeded. OLI-2, the updated sensor for L9, transmits data at 14 bits compared to the L8 12-bit transmission, allowing for finer data resolution. OLI-2 offers a 25–30% improvement in the signal-to-noise ratio for dark targets, leading to enhanced data quality. The Thermal Infrared Sensor on L9 (TIRS-2) has also been improved over TIRS on L7 and L8, to mitigate stray light issues, enhancing the reliability of thermal data. Additionally, OLI-2 supports better atmospheric corrections through split window techniques using both of its channels. With two operational observatories, L8 and L9, equipped with advanced radiometry, data is provided every eight days, ensuring consistent and precise Earth observation capabilities. The radiometric and geometric performance of L9 is excellent from a Calibration/Validation (Cal/Val) perspective.

While all systems are nominal for L8 and L9, Neigh reported that L7 is nearing the end of its operational life. He stated that the Landsat Cal/Val team will continue its work for the duration of the mission as a joint USGS–NASA effort. He also highlighted the need for a global Analysis Ready Data framework and the development of proxy and simulated datasets to support the next generation of Landsat missions. Neigh ended by reporting that opportunities exist for scientists to share their high-profile, Landsat-based research through the program’s communications team.

Bruce Cook [GSFC—Landsat Next Project Scientist] provided an update on the Landsat Next mission, an ambitious extension of the Landsat Program under the Sustainable Land Imaging (SLI) program, which will be a joint effort by NASA and the USGS. Cook explained that this mission aims to greatly enhance Earth observation by launching three identical satellites, each equipped with advanced Visible Shortwave Infrared (VSWIR) and Thermal Infrared (TIR) instruments. He described how the Landsat Next constellation will improve the temporal revisit time to six days – a major advancement from the 16-day interval of L8 and L9. In order to achieve this revisit time improvement, each satellite will carry a Landsat Next Instrument Suite (LandIS) that will capture 21 VSWIR and five thermal infrared bands, which will have better spatial resolutions compared to previous Landsat missions. It will have ground sample distances of 10–20 m (33–66 ft) for visible, near infrared, and shortwave infrared bands and 60 m (197 ft) for atmospheric visible SWIR and thermal infrared bands.

Cook continued with details on LandIS, stating that Landsat Next will record 26 bands in total – 15 more than the currently active L8 and L9 missions. The LandIS will include refined versions of the 11 Landsat “heritage” bands to ensure continuity, five new bands similar to the ESA’s Copernicus Sentinel-2 mission for improved data integration, and 10 new spectral bands to meet evolving user needs and applications. Additionally, Landsat Next will have a water vapor band for atmospheric correction without needing data from other satellites. LandIS will collect all bands nearly simultaneously, reducing illumination variations between bands and aiding in cloud detection and the generation of multispectral surface reflectance and thermal emission products (e.g., evapotranspiration).

Cook said that Landsat Next is in Phase A of its mission life cycle. The current focus is on defining science requirements and converting them into specific hardware and system designs. He said that this phase is crucial for setting up the subsequent phases. Phase B will involve preliminary design and technology completion, and later phases leading to the final design, fabrication, and launch of the satellites. He ended by emphasizing that the introduction of a new reference system and a lower orbit will further enhance the satellites’ ability to capture high-quality data, leading to a significant advancement in Earth observation technology.

Harmonized Landsat–Sentinel Project Update

Junchang Ju [GSFC] discussed the Harmonized Landsat Sentinel-2 (HLS) project, which aims to integrate data from the L8, L9, Sentinel-2A, and Sentinel-2B satellites for more frequent and detailed Earth observations. Currently the MODIS climate modeling grid data is used for atmospheric correction – see Figure 4. The newer HLS version will use VIIRS-based water vapor and ozone fields instead of MODIS data for atmospheric correction using the land surface reflectance code. Ju explained how HLS adopts the Military Grid Reference System used by Sentinel-2. HLS V2.0 corrects a mistake in view angle normalization of earlier versions (V1.3 and V1.4). Atmospherically corrected data from Hyperion (an instrument on NASA’s Earth Observing–1 extended mission) is used to make bandpass adjustments. A temporally complete global HLS V2.0 dataset has been available since August 2023. He also highlighted the availability and access of HLS data through various platforms – e.g., EarthData and WorldView, in Amazon Web Services and the project’s future plans, such as enhancing vegetation indices, cloud mask improvements, and 10-m (33-ft) improved resolution product.

NISAR Update

Gerald Bawden [NASA HQ—NISAR Program Scientist] delivered a presentation about the NISAR mission, which is a collaborative effort between NASA and the ISRO. He explained that NISAR will be a dual-frequency Synthetic Aperture Radar satellite using 24-cm (9-in) L-band and 10-cm (4-in) S-band radar frequencies. This dual-frequency approach will enable high-resolution imaging of Earth’s surface, offering near-global land and ice coverage with a 12-day repeat cycle for interferometry and approximately 6-day coverage using both ascending and descending orbits. The mission’s goals include providing valuable data to understand and manage climate variability, carbon dynamics, and catastrophic events (e.g., earthquakes). Specific applications include monitoring deformation, measuring ice sheet velocities, observing sea-ice deformation, and assessing biomass and crop disturbances. Bawden discussed NISAR’s data products, which will include raw radar data (Level-0) and geocoded single-look complex images and multi-look interferograms (Level-2). He stated that these data products will be crucial for various research and practical applications, including ecological forecasting, wildfire management, resource management, and disaster response. NISAR’s data will be openly accessible to the global scientific community through the Alaska Satellite Facility Data Active Archive Center. Initially planned for early 2024, the NISAR launch has been delayed to 2025. Bawden reported that NISAR will undergo a three-month commissioning phase after launch – before starting science operations. He also emphasized NASA’s commitment to open science, with NISAR’s data processing software and algorithms being made available as open-source tools, accompanied by training resources to facilitate their use.

Land Surface Disturbance Alert Classification System Update

Matthew Hansen [UMD] focused on the Land Surface Disturbance Alert (DIST-ALERT) classification system, designed for near-real-time global vegetation extent and loss mapping. He described the DIST-ALERT system, which uses HLS data, combining inputs from L8, L9, Sentinel-2A, and -2B to achieve a high-revisit rate of approximately 2–3 days at a 30-m (98-ft) resolution. DIST-ALERT operates with a primary algorithm that tracks vegetation loss through time-series analysis of fractional vegetation cover (FVC) and a secondary algorithm that detects general spectral anomalies. The system integrates drone data from various biomes to build a k-nearest neighbors model that is applied globally to predict FVC at the HLS-pixel scale. Hansen explained that DIST-ALERT monitors disturbances by comparing current vegetation fraction against a seasonal baseline, capturing changes such as forest fires, logging, mining, urban expansion, drought, and land conversion. He concluded by highlighting some case studies, including analysis of forest fires in Quebec, Canada, logging in the Republic of Congo, and gold mining in Ghana. He also said that the team released an improved version (V1) in March 2024, following a provisional release (V0) that was operational from February 2023 to February 2024.

State of LCLUC Report

Chris Justice [UMD—LCLUC Program Scientist] provided comments on the current state of the LCLUC program, followed by an open discussion to gather feedback. He emphasized the need for PI’s to effectively communicate their work to the broader community and highlighted the recent LCLUC initiative to create policy-oriented briefs based on research results, demonstrating its relevance to the Earth Science to Action Strategy. Justice acknowledged that challenges lie ahead for the LCLUC program – particularly considering the anticipated resource constraints in the coming year. He noted that the program plans to strengthen its position by forming partnerships with other ESD program elements and increasing involvement across NASA Centers. The program is also emphasizing the use of advanced remote sensing technologies, AI, and deep-learning data analytics, to deliver more precise and actionable insights into land dynamics contributing to better decision-making and policy development in land management and environmental conservation.

Justice also suggested the need for better integration between different scientific fields (i.e., between LCLUC and climatology, climate mitigation, and adaptation) to enhance interdisciplinary research and collaboration. He cited the current program solicitation (e.g., ROSES 2024 A.2) as an example of this integration and the recent IDS solicitation in ROSES 2022 A.28. Justice reminded participants that the solicitation focuses on collaborating with AIST to develop Land Digital Twins that incorporate available remote sensing data time series as non-static boundary conditions in weather forecast and climate models. Improvements in model forecasts and climate simulations will highlight the importance of accounting for LCLUC in these models – advancing the goals of the IPCC.

Conclusion

Garik Gutman concluded the meeting by summarizing key points raised about data management strategies, educational outreach efforts, LCLUC research outside the U.S., and current and upcoming projects. He highlighted that the program requires PIs to provide metadata for data products generated under NASA-funded projects, ensuring these resources are freely and openly accessible to the scientific community. Gutman acknowledged the challenges of conducting research and fieldwork in foreign countries due to funding and, at times, security issues, but praised the PIs for their efforts to expand the program globally. He also noted the program’s outreach efforts, which include engaging PIs, collaborators, and interested parties through its website, newsletters, webinars, and policy briefs. LCLUC emphasizes the importance of effectively communicating research results and encourages researchers to share their findings via NASA’s Earth Sciences Research Results Portal to enhance visibility among leadership and communication teams.

Gutman ended his presentation by providing details about forthcoming meetings in the Philippines, South Korea, and Turkey, as well as workshops scheduled for 2024, which will involve various stakeholders in the LCLUC community and are vital for fostering collaboration and advancing the program’s goals. He concluded by recognizing the contributions of long-term supporters and collaborators, reaffirming the program’s ongoing commitment to advancing Earth observation and land-use science.

Overall, the 2024 LCLUC meeting was highly successful in fostering collaboration among researchers and providing valuable updates on recent developments in LCLUC research. The exchange of ideas, integration of new data products, and discussions on emerging science directions were particularly impactful, contributing to the advancement of the LCLUC program’s goals.

      Robert Williams is a senior mechanical design engineer and the structures subject matter expert in the Engineering and Test Directorate at NASA’s Stennis Space Center.NASA/Danny Nowlin Living up to, and maintaining, the standard of excellence associated with NASA is what drives Robert Williams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
      A native of Gulfport, Mississippi, Williams said he has had the opportunity to work with and be mentored by “some truly exceptional” engineers, some with careers reaching back to the Apollo era.
      “I cannot overstate the vast amount of practical knowledge and experience we have at NASA Stennis,” Williams said. “We know how to get things done, and if we do not know, I can guarantee we will figure it out.”
      Williams is a senior mechanical design engineer and the structures subject matter expert for the NASA Stennis Engineering and Test Directorate.
      He provides technical oversight related to engineering mechanics and machine design by reviewing analysis and design packages from NASA Stennis contractors and NASA engineers for ongoing projects.
      Williams also supports projects by performing analysis and creating detailed models, drawings, and system level designs, mostly at the versatile four-stand E Test Complex, where NASA Stennis has 12 active test cells capable of various component, engine, and stage test activities to support the agency and commercial companies.
      In support of NASA’s Artemis campaign of returning astronauts to the Moon, Williams also has reviewed structural and pipe stress analysis for the exploration upper stage project that will test a new SLS (Space Launch System) rocket stage to fly on future Artemis missions.
      He performed similar review work for Green Run testing of the SLS core stage at NASA Stennis ahead of the successful launch of the Artemis I uncrewed mission around the Moon. 
      Overall, Williams has been a part of projects on every test stand throughout more than eight years with NASA and five years as a contractor. He has been tasked with solving challenging problems, both individually and as a part of teams.
      There were times when he was not sure if he or the team would be able to solve the problem or address it effectively, but each time, the NASA Stennis team found a way.
      “Over the span of my career, I have yet to be in a situation where the challenge was not met,” he said.
      The opportunity to work with “pretty much all the major space companies in some capacity” is most interesting to Williams. “The best thing is that being a small organization within a relatively small center, there are always opportunities to develop new skills and capabilities to help fill a need or gap,” he said.
      No matter the task, Williams looks forward to supporting space innovation while living up to, and maintaining, the standard of excellence associated with NASA for the benefit of all.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s SPHEREx mission is observing the entire sky in 102 infrared colors, or wavelengths of light not visible to the human eye. This image shows a section of sky in one wavelength (3.29 microns), revealing a cloud of dust made of a molecule similar to soot or smoke.NASA/JPL-Caltech This image from NASA’s SPHEREx shows the same region of space in a different infrared wavelength (0.98 microns), but the dust cloud is no longer visible. The molecules that compose the dust — polycyclic aromatic hydrocarbons — do not radiate light in this color.NASA/JPL-Caltech After weeks of preparation, the space observatory has begun its science mission, taking about 3,600 unique images per day to create a map of the cosmos like no other.
      Launched on March 11, NASA’s SPHEREx space observatory has spent the last six weeks undergoing checkouts, calibrations, and other activities to ensure it is working as it should. Now it’s mapping the entire sky — not just a large part of it — to chart the positions of hundreds of millions of galaxies in 3D to answer some big questions about the universe. On May 1, the spacecraft began regular science operations, which consist of taking about 3,600 images per day for the next two years to provide new insights about the origins of the universe, galaxies, and the ingredients for life in the Milky Way.
      This video shows SPHEREx’s field of view as it scans across one section of sky inside the Large Magellanic Cloud, with rainbow colors representing the infrared wavelengths the telescope’s detectors see. The view from one detector array moves from purple to green, followed by the second array’s view, which changes from yellow to red. The images are looped four times. NASA/JPL-Caltech “Thanks to the hard work of teams across NASA, industry, and academia that built this mission, SPHEREx is operating just as we’d expected and will produce maps of the full sky unlike any we’ve had before,” said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. “This new observatory is adding to the suite of space-based astrophysics survey missions leading up to the launch of NASA’s Nancy Grace Roman Space Telescope. Together with these other missions, SPHEREx will play a key role in answering the big questions about the universe we tackle at NASA every day.”
      From its perch in Earth orbit, SPHEREx peers into the darkness, pointing away from the planet and the Sun. The observatory will complete more than 11,000 orbits over its 25 months of planned survey operations, circling Earth about 14½ times a day. It orbits Earth from north to south, passing over the poles, and each day it takes images along one circular strip of the sky. As the days pass and the planet moves around the Sun, SPHEREx’s field of view shifts as well so that after six months, the observatory will have looked out into space in every direction.
      When SPHEREx takes a picture of the sky, the light is sent to six detectors that each produces a unique image capturing different wavelengths of light. These groups of six images are called an exposure, and SPHEREx takes about 600 exposures per day. When it’s done with one exposure, the whole observatory shifts position — the mirrors and detectors don’t move as they do on some other telescopes. Rather than using thrusters, SPHEREx relies on a system of reaction wheels, which spin inside the spacecraft to control its orientation.
      Hundreds of thousands of SPHEREx’s images will be digitally woven together to create four all-sky maps in two years. By mapping the entire sky, the mission will provide new insights about what happened in the first fraction of a second after the big bang. In that brief instant, an event called cosmic inflation caused the universe to expand a trillion-trillionfold.
      “We’re going to study what happened on the smallest size scales in the universe’s earliest moments by looking at the modern universe on the largest scales,” said Jim Fanson, the mission’s project manager at NASA’s Jet Propulsion Laboratory in Southern California. “I think there’s a poetic arc to that.”
      Cosmic inflation subtly influenced the distribution of matter in the universe, and clues about how such an event could happen are written into the positions of galaxies across the universe. When cosmic inflation began, the universe was smaller than the size of an atom, but the properties of that early universe were stretched out and influence what we see today. No other known event or process involves the amount of energy that would have been required to drive cosmic inflation, so studying it presents a unique opportunity to understand more deeply how our universe works.
      “Some of us have been working toward this goal for 12 years,” said Jamie Bock, the mission’s principal investigator at Caltech and JPL. “The performance of the instrument is as good as we hoped. That means we’re going to be able to do all the amazing science we planned on and perhaps even get some unexpected discoveries.”
      Color Field
      The SPHEREx observatory won’t be the first to map the entire sky, but it will be the first to do so in so many colors. It observes 102 wavelengths, or colors, of infrared light, which are undetectable to the human eye. Through a technique called spectroscopy, the telescope separates the light into wavelengths — much like a prism creates a rainbow from sunlight — revealing all kinds of information about cosmic sources.
      For example, spectroscopy can be harnessed to determine the distance to a faraway galaxy, information that can be used to turn a 2D map of those galaxies into a 3D one. The technique will also enable the mission to measure the collective glow from all the galaxies that ever existed and see how that glow has changed over cosmic time.
      And spectroscopy can reveal the composition of objects. Using this capability, the mission is searching for water and other key ingredients for life in these systems in our galaxy. It’s thought that the water in Earth’s oceans originated as frozen water molecules attached to dust in the interstellar cloud where the Sun formed.
      The SPHEREx mission will make over 9 million observations of interstellar clouds in the Milky Way, mapping these materials across the galaxy and helping scientists understand how different conditions can affect the chemistry that produced many of the compounds found on Earth today.
      More About SPHEREx
      The SPHEREx mission is managed by JPL for the agency’s Astrophysics Division within the Science Mission Directorate at NASA Headquarters. BAE Systems in Boulder, Colorado, built the telescope and the spacecraft bus. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions in the U.S., two in South Korea, and one in Taiwan. Caltech in Pasadena managed and integrated the instrument. The mission’s principal investigator is based at Caltech with a joint JPL appointment. Data will be processed and archived at IPAC at Caltech. The SPHEREx dataset will be publicly available at the NASA-IPAC Infrared Science Archive. Caltech manages JPL for NASA.

      A number of NASA projects use mobile phone apps to put satellite data into the palm of your hand, and allow intrepid citizen scientists to upload data. Credits:
      NASA A cell phone, a computer—and your curiosity—is all you need to become a NASA citizen scientist and contribute to projects about Earth, the solar system, and beyond.
      Science is built from small grains of sand, and you can contribute yours from any corner of the world.
      All you need is a cell phone or a computer with an internet connection to begin a scientific adventure. Can you imagine making a pioneering discovery in the cosmos? Want to help solve problems that could improve life on our planet? Or maybe you dream of helping solve an ancient mystery of the universe? All of this is possible through NASA’s Citizen Science program.
      NASA defines citizen science, or participatory science, as “science projects that rely on volunteers,” said Dr. Marc Kuchner, an astrophysicist and the Citizen Science Officer in the agency’s Science Mission Directorate in Washington, D.C.
      For decades, volunteers have been supporting NASA researchers in different fields and in a variety of ways, depending on the project. They help by taking measurements, sorting data from NASA missions, and deepening our understanding of the universe and our home planet. It all counts.
      “That’s science for you: It’s collaborative,” said Kuchner, who oversees the more than 30 citizen science projects NASA offers. “I connect the public and scientists to get more NASA science done.”
      NASA astrophysicist Marc Kuchner is a pioneer in participatory science and today serves as NASA’s Citizen Science program officer. In 2014, Kuchner created the Disk Detective project, which helps NASA scientists study how planets form. Kuchner has also been the principal investigator for some of the agency’s many citizen science projects, but today he oversees the portfolio and promotes volunteer participation around the world.

      Citizen scientists can come from anywhere in the world—they do not have to be U.S. citizens or residents. Volunteers help NASA look for planets in other solar systems, called exoplanets; sort clouds in Earth’s sky; observe solar eclipses; or detect comets and asteroids. Some of those space rocks are even named after the volunteers who helped find them.
      Mass participation is key in initiatives that require as many human eyes as possible. “There are science projects that you can’t do without the help of a big team,” Kuchner said. For example, projects that need large datasets from space telescopes—or “things that are physically big and you need people in different places looking from different angles,” he said.
      One example is Aurorasaurus, which invites people to observe and classify northern and southern auroras. “We try to study them with satellites, but it really helps to have people on the ground taking photos from different places at different times,” he explained.
      “Part of the way we serve our country and humankind is by sharing not just the pretty pictures from our satellites, but the entire experience of doing science,” Kuchner said.
      More than 3 million people have participated in the program. Kuchner believes that shows how much people want to be part of what he calls the “roller coaster” of science. “They want to go on that adventure with us, and we are thrilled to have them.”
      The dream of discovering
      “You can help scientists who are now at NASA and other organizations around the world to discover interesting things,” said Faber Burgos, a citizen scientist and science communicator from Colombia. “Truth be told, I’ve always dreamed of making history.”
      Colombian citizen scientist Faber Burgos studied Modern Languages at the Colombian School of Industrial Careers and has a university degree in Classical Archaeology. Today, he is dedicated to disseminating science content through his social media accounts, focusing on children. In 2020, he and his team launched a balloon probe into the stratosphere with a camera that captured the curvature of the Earth, with the aim of demonstrating that the Earth is round. The video of that feat exceeds 97 million views on his Facebook account, earning him a Guinness World Record.
      Credit: Courtesy of Faber Burgos Burgos has been involved in two projects for the past four years: the International Astronomical Search Collaboration (IASC), which searches the sky for potentially dangerous asteroids, and Backyard Worlds: Planet 9. This project uses data from NASA’s now-completed Wide-field Infrared Survey Explorer (WISE) and its follow-up mission, NEOWISE, to search for brown dwarfs and a hypothetical ninth planet.
      “There are really amazing participants in this project,” said Kuchner, who helped launch it in 2015. NASA’s WISE and NEOWISE missions detected about 2 billion sources in the sky. “So, the question is: Among those many sources, are any of them new unknowns?” he said.
      The project has already found more than 4,000 brown dwarfs. These are Jupiter-sized objects—balls of gas that are too big to be planets, but too small to be stars. Volunteers have even helped discover a new type of brown dwarf.
      Participants in the project are also hopeful they’ll find a hypothetical ninth planet, possibly Neptune-sized, in an orbit far beyond Pluto.
      The Backyard Worlds: Planet 9 citizen science project asks volunteers to help search for new objects at the edge of our solar system. The assignment is to review images from NASA’s past WISE and NEOWISE missions in search of two types of astronomical objects: brown dwarfs(balls of gas the same size as  Jupiter that have too little mass to be considered stars) and low-mass stars. Or, even, the hypothetical ninth planet of our Sun, known as Planet nine, or Planet X. The image shows an artist’s rendering of such a hypothetical world orbiting far from the Sun.
      Credit: Caltech/R. Hurt (IPAC) Caltech/R. Hurt (IPAC) Burgos explained that analyzing the images is easy. “If it’s a moving object, it’s obviously going to be something of interest,” he said. “Usually, when you see these images, everything is still. But if there’s an object moving, you have to keep an eye on it.”
      Once a citizen scientist marks the object across the full image sequence, they send the information to NASA scientists to evaluate.
      “As a citizen scientist, I’m happy to do my bit and, hopefully, one day discover something very interesting,” he said. “That’s the beauty of NASA—it invites everyone to be a scientist. Here, it doesn’t matter what you are, but your desire to learn.”
      The first step
      To become a NASA citizen scientist, start by visiting the program’s website. There you’ll find a complete list of available projects with links to their respective sites. Some are available in Spanish and other languages. Many projects are also hosted on the Zooniverse platform, which has been available since 2006.
      “Another cool way to get involved is to come to one of our live events,” said Kuchner. These are virtual events open to the public, where NASA scientists present their projects and invite people to participate. “Pick a project you like—and if it’s not fun, pick a different one,” he advised. “There are wonderful relationships to be had if you reach out to scientists and other participants.”
      Another way for people to get involved in citizen science is to participate in the annual NASA International Space Apps Challenge, the largest global hackathon. This two-day event creates innovation through international collaboration, providing an opportunity for participants to use NASA’s free and open data and agency partners’ space-based data to tackle real-world problems on Earth and in space. The next NASA International Space Apps Challenge will be October 4-5, 2025.
      Credit: NASA Age is not the limit
      People of all ages can be citizen scientists. Some projects are kid-friendly, such as Nemo-Net, an iPad game that invites participants to color coral reefs to help sort them. “I’d like to encourage young people to start there—or try a project with one of the older people in their life,” Kuchner said.
      Citizen science can also take place in classrooms. In the Growing Beyond Earth project, teachers and students run experiments on how to grow plants in space for future missions. The IASC project also works with high schools to help students detect asteroids.

      GLOBE Observer is another initiative with an international network of teachers and students. The platform offers a range of projects—many in Spanish—that invite people to collect data using their cell phones.
      One of the most popular is the GLOBE Mosquito Habitat Mapper, which tracks the migration and spread of mosquitoes that carry diseases. “It’s a way to help save lives—tracking the vectors that transmit malaria and Zika, among others,” Kuchner said.
      Other GLOBE projects explore everything from ground cover to cloud types. Some use astronomical phenomena visible to everyone. For example, during the 2024 total solar eclipse, participants measured air temperature using their phones and shared that data with NASA scientists.
      The full experience of doing science
      No prior studies are needed, but many volunteers go on to collaborate on—or even lead—scientific research. More than 500 NASA citizen scientists have co-authored scientific publications.
      One of them is Hugo Durantini Luca, from Córdoba, Argentina, who has participated in 17 published articles, with more on the way. For years, he explored various science projects, looking for one where he could contribute more actively.
      Durantini Luca participated in one of NASA’s first citizen science projects, launched in 2006: Stardust at home. Still ongoing, this project invites volunteers to participate in the search for evidence of interstellar dust on the aerogel and aluminum foil collectors returned by NASA’s Stardust mission, using an online virtual microscope.
      Credit: NASA He participated in NASA’s first citizen science project, Stardust@home, which invites users to search for interstellar dust particles in collectors from the Stardust mission, using a virtual microscope.
      In 2014, he discovered Disk Detective, a project that searches for disks around stars, where planets may form. By looking at images from the WISE and NEOWISE missions, participants can help understand how worlds are born and how solar systems evolve.
      “And, incidentally, if we find planets or some sign of life, all the better,” said Durantini Luca.
      Although that remains a dream, they have made other discoveries—like a new kind of stellar disk called the “Peter Pan Disk,” which appears young even though the star it surrounds is not.

      In 2016, Durantini Luca got the chance to support Disk Detective with his own observations from the southern hemisphere. He traveled to El Leoncito Astronomical Complex (CASLEO), an observatory in San Juan, Argentina. There, he learned to use a spectrograph—an instrument that breaks down starlight to analyze its composition.
      He treasures that experience. “Curiously, it was the first time in my life I used a telescope,” he said.
      In 2016, citizen scientist Hugo Durantini Luca traveled for 18 hours to the El Leoncito Astronomical Complex (CASLEO), at the foot of the Andes Mountains. From there, he made observations of a candidate star of the Disk Detective project.
      Credit: Luciano García While in-person opportunities are rare, both virtual and physical events help build community. Citizen scientists stay in touch weekly through various channels.
      “Several of us are friends already—after so many years of bad jokes on calls,” said Durantini Luca.
      “People send me pictures of how they met,” said Kuchner. He said the program has even changed how he does science. “It’s changed my life,” he said. “Science is already cool—and this makes it even cooler.”

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      JunoCam, the visible light imager aboard NASA’s Juno, captured this enhanced-color view of Ju-piter’s northern high latitudes from an altitude of about 36,000 miles (58,000 kilometers) above the giant planet’s cloud tops during the spacecraft’s 69th flyby on Jan. 28, 2025. Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing: Jackie Branc (CC BY) New data from the agency’s Jovian orbiter sheds light on the fierce winds and cyclones of the gas giant’s northern reaches and volcanic action on its fiery moon.
      NASA’s Juno mission has gathered new findings after peering below Jupiter’s cloud-covered atmosphere and the surface of its fiery moon, Io. Not only has the data helped develop a new model to better understand the fast-moving jet stream that encircles Jupiter’s cyclone-festooned north pole, it’s also revealed for the first time the subsurface temperature profile of Io, providing insights into the moon’s inner structure and volcanic activity.
      Team members presented the findings during a news briefing in Vienna on Tuesday, April 29, at the European Geosciences Union General Assembly.
      “Everything about Jupiter is extreme. The planet is home to gigantic polar cyclones bigger than Australia, fierce jet streams, the most volcanic body in our solar system, the most powerful aurora, and the harshest radiation belts,” said Scott Bolton, principal investigator of Juno at the Southwest Research Institute in San Antonio. “As Juno’s orbit takes us to new regions of Jupiter’s complex system, we’re getting a closer look at the immensity of energy this gas giant wields.”

      While Juno’s microwave radiometer (MWR) was designed to peer beneath Jupiter’s cloud tops, the team has also trained the instrument on Io, combining its data with Jovian Infrared Auroral Mapper (JIRAM) data for deeper insights.
      “The Juno science team loves to combine very different datasets from very different instruments and see what we can learn,” said Shannon Brown, a Juno scientist at NASA’s Jet Propulsion Laboratory in Southern California. “When we incorporated the MWR data with JIRAM’s infrared imagery, we were surprised by what we saw: evidence of still-warm magma that hasn’t yet solidified below Io’s cooled crust. At every latitude and longitude, there were cooling lava flows.”
      The data suggests that about 10% of the moon’s surface has these remnants of slowly cooling lava just below the surface. The result may help provide insight into how the moon renews its surface so quickly as well as how as well as how heat moves from its deep interior to the surface.
      “Io’s volcanos, lava fields, and subterranean lava flows act like a car radiator,” said Brown, “efficiently moving heat from the interior to the surface, cooling itself down in the vacuum of space.”
      Looking at JIRAM data alone, the team also determined that the most energetic eruption in Io’s history (first identified by the infrared imager during Juno’s Dec. 27, 2024, Io flyby) was still spewing lava and ash as recently as March 2. Juno mission scientists believe it remains active today and expect more observations on May 6, when the solar-powered spacecraft flies by the fiery moon at a distance of about 55,300 miles (89,000 kilometers).
      This composite image, derived from data collected in 2017 by the JIRAM instrument aboard NASA’s Juno, shows the central cyclone at Jupiter’s north pole and the eight cy-clones that encircle it. Data from the mission indicates these storms are enduring fea-tures.NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM Colder Climes
      On its 53rd orbit (Feb 18, 2023), Juno began radio occultation experiments to explore the gas giant’s atmospheric temperature structure. With this technique, a radio signal is transmitted from Earth to Juno and back, passing through Jupiter’s atmosphere on both legs of the journey. As the planet’s atmospheric layers bend the radio waves, scientists can precisely measure the effects of this refraction to derive detailed information about the temperature and density of the atmosphere.
      So far, Juno has completed 26 radio occultation soundings. Among the most compelling discoveries: the first-ever temperature measurement of Jupiter’s north polar stratospheric cap reveals the region is about 11 degrees Celsius cooler than its surroundings and is encircled by winds exceeding 100 mph (161 kph).
      Polar Cyclones
      The team’s recent findings also focus on the cyclones that haunt Jupiter’s north. Years of data from the JunoCam visible light imager and JIRAM have allowed Juno scientists to observe the long-term movement of Jupiter’s massive northern polar cyclone and the eight cyclones that encircle it. Unlike hurricanes on Earth, which typically occur in isolation and at lower latitudes, Jupiter’s are confined to the polar region.
      By tracking the cyclones’ movements across multiple orbits, the scientists observed that each storm gradually drifts toward the pole due to a process called “beta drift” (the interaction between the Coriolis force and the cyclone’s circular wind pattern). This is similar to how hurricanes on our planet migrate, but Earthly cyclones break up before reaching the pole due to the lack of warm, moist air needed to fuel them, as well as the weakening of the Coriolis force near the poles. What’s more, Jupiter’s cyclones cluster together while approaching the pole, and their motion slows as they begin interacting with neighboring cyclones.
      “These competing forces result in the cyclones ‘bouncing’ off one another in a manner reminiscent of springs in a mechanical system,” said Yohai Kaspi, a Juno co-investigator from the Weizmann Institute of Science in Israel. “This interaction not only stabilizes the entire configuration, but also causes the cyclones to oscillate around their central positions, as they slowly drift westward, clockwise, around the pole.”
      The new atmospheric model helps explain the motion of cyclones not only on Jupiter, but potentially on other planets, including Earth.
      “One of the great things about Juno is its orbit is ever-changing, which means we get a new vantage point each time as we perform a science flyby,” said Bolton. “In the extended mission, that means we’re continuing to go where no spacecraft has gone before, including spending more time in the strongest planetary radiation belts in the solar system. It’s a little scary, but we’ve built Juno like a tank and are learning more about this intense environment each time we go through it.”

      NASA completed stacking the twin solid rocket boosters for Artemis II, the mission that will send American astronauts around the Moon for the first time in more than 50 years. This is a powerful step toward returning our nation to deep space. At NASA’s Kennedy Space Center in Florida, teams joined the core stage with the solid rocket boosters inside the Vehicle Assembly Building. Engineers lifted the launch vehicle stage adapter atop the SLS (Space Launch System) core stage, connecting key systems that will soon power NASA’s return to the Moon. Teams received the Interim Cryogenic Propulsion Stage and moved the SLS core stage into the transfer aisle, clearing another milestone as the agency prepares to fully integrate America’s most powerful rocket. NASA attached the solar array wings that will help power the Orion spacecraft on its journey around the Moon, laying the groundwork for humanity’s next giant leap. Technicians installed the protective fairings on Orion’s service module to shield the spacecraft during its intense launch and ascent phase, as NASA prepares to send astronauts farther than any have gone in more than half a century. The agency’s next-generation mobile launcher continues to take shape, with the sixth of 10 massive modules being installed. This structure will carry future Artemis rockets to the launch pad. NASA and the Department of Defense teamed up aboard the USS Somerset for Artemis II recovery training, ensuring the agency and its partners are ready to safely retrieve Artemis astronauts after their historic mission around the Moon. NASA unveiled the Artemis II mission patch. The patch designates the mission as “AII,” signifying not only the second major flight of the Artemis campaign but also an endeavor of discovery that seeks to explore for all and by all. America First in Space
      NASA announced the first major science results from asteroid Bennu, revealing ingredients essential for life, a discovery made possible by U.S. leadership in planetary science through the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission. The team found salty brines, 14 of the 20 amino acids used to make proteins, and all five DNA nucleobases, suggesting that the conditions and ingredients for life were widespread in our early solar system. And this is just the beginning – these results were from analysis of only 0.06% of the sample. NASA was named one of TIME’s Best Companies for Future Leaders, underscoring the agency’s role in cultivating the next generation of American innovators. NASA awarded contracts to U.S. industry supporting Earth science missions,  furthering our understanding of the planet while strengthening America’s industrial base. As part of the Air Traffic Management-Exploration project, NASA supported Boeing’s test of digital and autonomous taxiing with a Cessna Caravan at Moffett Federal Airfield. The test used real-time simulations from the agency’s Future Flight Central to gather data that will help Boeing refine its systems and safely integrate advanced technologies into national airspace, demonstrating American aviation leadership. NASA successfully completed its automated space traffic coordination objectives between the agency’s four Starling spacecraft and SpaceX’s Starlink constellation. Teams demonstrated four risk mitigation maneuvers, autonomously resolving close approaches between two spacecraft with different owner/operators.   In collaboration with the National Institute of Aeronautics, NASA selected eight finalists in a university competition aimed at designing innovative aviation solutions that can help the agriculture industry. NASA’s Gateways to Blue Skies seeks ways to apply American aircraft and aviation technology to enhance the productivity, efficiency, and resiliency of American farms.  In Houston, United Airlines pilots successfully conducted operational tests of NASA-developed technologies designed to reduce flight delays. Using technologies from the Air Traffic Management Exploration project, pilots flew efficient re-routes, avoiding airspace with bad weather upon departure. United plans to expand the use of these capabilities, another example of how NASA innovations benefit all humanity.  On March 11, NASA’s newest astrophysics observatory, SPHEREx, launched on its journey to answer fundamental questions about our universe, thanks to the dedication and expertise of the agency’s team. Riding aboard a SpaceX Falcon 9 from Vandenberg Space Force Base, SPHEREx will scan the entire sky to study how galaxies formed, search for the building blocks of life, and look back to the universe’s earliest moments. After launch, SPHEREx turned on its detectors, and everything is performing as expected. Also onboard were four small satellites for NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which will help scientists understand how the Sun’s outer atmosphere becomes solar wind. These missions reflect the best of the agency – pushing the boundaries of discovery and expanding our understanding of the cosmos. On March 14, NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission launched from Vandenberg Space Force Base. This trio of small satellites will study auroral electrojets, or intense electric currents flowing high above Earth’s poles, helping the agency better understand space weather and its effects on our planet. The mission has taken its first measurements, demonstrating that the spacecraft and onboard instrument are working as expected. The X-59 quiet supersonic aircraft cleared another hurdle on its way to first flight. The team successfully completed an engine speed hold test, confirming the “cruise control” system functions as designed.  NASA researchers successfully tested a prototype that could help responders fight and monitor wildfires, even in low-visibility conditions. The Portable Airspace Management System, developed by NASA’s Advanced Capabilities for Emergency Response Operations project, safely coordinated simulated operations involving drones and other aircraft, tackling a major challenge for those on the front lines. This is just one example of how NASA’s innovation is making a difference where it’s needed most.  NASA’s Parker Solar Probe completed its 23rd close approach to the Sun, coming within 3.8 million miles of the solar surface while traveling at 430,000 miles per hour – matching its own records for distance and speed. That same day, Parker Solar Probe was awarded the prestigious Collier Trophy, a well-earned recognition for its groundbreaking contributions to heliophysics.  In response to severe weather that impacted more than 10 states earlier this month, the NASA Disasters Response Coordination System activated to support national partners. NASA worked closely with the National Weather Service and the Federal Emergency Management Agency serving the central and southeastern U.S. to provide satellite data and expertise that help communities better prepare, respond, and recover.  As an example of how NASA’s research today is shaping the transportation of tomorrow, the agency’s aeronautics engineers began a flight test campaign focused on safely integrating air taxis into the national airspace. Using a Joby Aviation demonstrator aircraft, engineers are helping standardize flight test maneuvers, improving tools to assist with collision avoidance and landing operations, and ensuring safe and efficient air taxis operations in various weather conditions. NASA premiered “Planetary Defenders,” a new documentary that follows the dedicated team behind asteroid detection and planetary defense. The film debuted at an event at the agency’s headquarters with digital creators, interagency and international partners, and now is streaming on NASA+, YouTube, and X. In its first 24 hours, it saw 25,000 views on YouTube – 75% above average – and reached 4 million impressions on X.  Finland became the 53rd nation to sign the Artemis Accords, reaffirming its commitment to the peaceful, transparent, and responsible exploration of space. This milestone underscores the growing global coalition led by the United States to establish a sustainable and cooperative presence beyond Earth. In Dhaka, Bangladesh, NASA welcomed a new signatory to the Artemis Accords. Bangladesh became the 54th nation to commit to the peaceful, safe, and responsible exploration of space. It’s a milestone that reflects our shared values and growing global momentum, reaffirming the United States’ leadership in building a global coalition for peaceful space exploration.  At NASA’s Armstrong Flight Research Center in Edwards, California, engineers conducted calibration flights for a new shock-sensing probe that will support future flight tests of the X-59 quiet supersonic demonstrator. Mounted on a research F-15D that will follow the X-59 closely in flight, the probe will gather data on the shock waves the X-59 generates, providing important data about its ability to fly faster than sound, but produce only a quiet thump. In its second asteroid encounter, Lucy flew by the asteroid Donaldjohanson and gave NASA a close look at a uniquely shaped fragment dating back 150 million years – an impressive performance ahead of its main mission target in 2027. A celebration of decades of discovery, NASA’s Hubble Space Telescope celebrated its 35th anniversary with new observations ranging from nearby solar system objects to distant galaxies – proof that Hubble continues to inspire wonder and advance our understanding of the universe. The SPHEREx team rang the closing bell at the New York Stock Exchange, spotlighting NASA’s newest space telescope and its bold mission to explore the origins of the universe. NASA received six Webby Awards and six People’s Voice Awards across platforms – recognition of America’s excellence in digital engagement and public communication. The NASA Electric Aircraft Testbed and Advanced Air Transport Technology project concluded testing of a 2.5-megawatt Wright Electric motor designed to eventually serve large aircraft. The testing used the project’s capabilities to simulate altitude conditions of up to 40,000 feet while the electric motor, the most powerful tested so far at the facility, ran at both full voltage and partial power. NASA partnered with the Department of Energy on the tests. U.S. entities can now request the Glenn Icing Computational Environment (GlennICE) tool from the NASA Software Catalog and discover solutions to icing challenges for novel engine and aircraft designs. A 3D computational tool, GlennICE allows engineers to integrate icing-related considerations earlier in the aircraft design process and enable safer, more efficient designs while saving costs in the design process.
