Jeff’s research focused on snow hydrology and biogeochemistry in mountain environments and addressed the role of stored and melting snow in the hydrologic cycle as well as the economic and social impact on water resources. In these efforts, he embraced remote sensing with satellites to measure snow properties and energy balance. He was a Project Scientist with the Earth Observing System (EOS) Data and Information System, contributing to the design and management of very large information systems that would impact spatial modeling and environmental informatics. Jeff served as the second EOS Project Scientist from 1990–1992. During that time, he worked with the NASA science community to – in his own words – “accomplish the goals of EOS, the most important of which is to develop the capability to predict or assess plausible environmental changes – both natural and human-induced – that will occur in the future. Meeting this challenge for the next decade to century requires the integration of knowledge from the traditional disciplines and information from many different sources into a coherent view of the Earth system. EOS is the largest project in the history of NASA and arguably the most important national and international scientific mission of the next two decades.” Jeff’s work alongside Michael Matson, was featured in a 2019 NASA Earth Science news article: “NASA Tracks Wildfires From Above to Aid Firefighters Below.” While working at NOAA’s National Environmental Satellite, Data, and Information Service building in Camp Springs, MD, the pair detected methane fires in the Persian Gulf using the Advanced Very High Resolution Radiometer (AVHRR) instrument on the NOAA-6 satellite – marking the first time that such a small fire had been seen from space. Jeff went on to develop a mathematical method to distinguish small fires from other sources of heat, which become the foundation for nearly all subsequent satellite fire-detection algorithms. At the time of his death, Jeff was Principal Investigator of a NASA-funded project with the objective of testing whether data from the Earth Surface Mineral Dust Source Investigation (EMIT) mission could be used to help refine the estimate for the snowpack melting rate. In the 2024 Earth Science news article, “NASA’s EMIT Will Explore Diverse Science Questions on Extended Mission,” Jeff indicated that EMIT’s ability to ‘see’ well into the infrared (IR) spectrum of light is key to his group’s efforts because ice is “pretty absorptive at near-IR and shortwave-IR wavelengths.” The results from this research will help inform water management decisions in states, such as California, where meltwater makes up the majority of the agricultural water supply. Jeff earned a Bachelor’s of Science degree from California State University, Hayward (now California State University, East Bay) and a Master’s of Science degree and Ph.D. from the University of Michigan. He spent his career teaching at the University of California, Santa Barbara (UCSB), where he was named the founding Dean of the Bren School of Environmental Science and Management at UCSB in 1994. As the Dean, he recruited renowned faculty and developed one of the top environmental programs in the country. After his role as Dean, Jeff returned as a professor at Bren, educating the next generation of Earth scientists. Jeff Dozier [1944–2024]Photo credit: Dozier’s family obituaryView the full article

Berrien earned an undergraduate degree from the University of North Carolina in 1963 and a doctorate degree from the University of Virginia in 1969. After graduating, he taught mathematics at the University of New Hampshire (UNH) and became tenured in 1976. In 1987, Berrien became director of the Institute for the Study of Earth, Oceans, and Space (ISEOS) at UNH. NASA chose ISEOS to be one of the 24 founding members of the “Working Prototype Federation” of Earth Science Information Partners (ESIP) in 1998. Still active more than 25 years later, ESIP is now a thriving nonprofit entity funded by cooperative agreements with NASA, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Geological Survey, which brings together interdisciplinary collaborations (among over 170 partners) to share technical knowledge and engage with data users. Berrien left UNH in 2008, to serve as the founding Executive Director of Climate Central, a think-tank based in Princeton, NJ, which is dedicated to providing objective and understandable information about climate change Berrien moved to OU in 2010. Given his diverse academic, research, and career experience in global carbon cycle, biogeochemistry, remote sensing, environmental and space policy, and mathematics, Berrien was a natural choice to become the architect and principal investigator for the Geostationary Carbon Cycle Observatory (GeoCARB), a proposed NASA Earth Venture Mission that would have monitored plant health and vegetation stress throughout the Americas from geostationary orbit, probing natural sources, sinks, and exchange processes that control carbon dioxide, carbon monoxide, and methane in the atmosphere. While the mission was ultimately cancelled, the lessons learned are being applied to similar current and future Earth observing endeavors, e,g, NASA’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission. Berrien served on and chaired numerous government-affiliated scientific committees throughout his career. From 1995–1998 he served on the National Research Council’s Committee on Global Change Research, which produced the landmark report, “Global Environment Change: Research Pathways for the Next Decade.” In 2011, he was an author on the National Research Council’s (NRC) decadal survey, “Earth Science and Applications from Space: A Community Assessment and Strategies for the Future.” Berrien participated on international scientific committees as well. From 1998–2002, he was the chair of the Science Committee of the International Geosphere Biosphere Programme (IGBP). He was also a lead author within the Intergovernmental Panel on Climate Change’s Third Assessment Report, which was released in 2001. Berrien served in several roles specific to NASA, including as a committee member and later chair of the organization’s Space and Earth Science Advisory Committee. He served as Chair of the Earth Observing System (EOS) Payload Advisory Committee, member and Chair of NASA’s Earth Science and Applications Committee, and member of the NASA Advisory Council. He was also active at NOAA, having chaired the agency’s Research Review Team and served on the Research and Development Portfolio Review Team for NOAA’s Science Advisory Board. Berrien received NASA’s highest civilian honor, the Distinguished Public Service Medal, for outstanding service and the NOAA Administrator’s Recognition Award. He also received the 2007 Dryden Lectureship in Research Medal from the American Institute of Aeronautics and Astronautics and was honored for his contributions to the IPCC when the organization received the 2007 Nobel Peace Prize.

During missions to the Moon, RS-25 engines fire for about 500 seconds and up to the 111% power level to help launch SLS, with the Orion spacecraft, into orbit. The engine arrived at the test stand from the L3Harris Engine Assembly Facility on the engine transport trailer before being lifted onto the vertical engine installer (VEI) on the west side deck. After rolling the engine into the stand, the team used the VEI to raise and secure it in place. The upcoming acceptance test follows two certification test series that helped verify the new engine production process and components meet all performance requirements. Four RS-25 engines help launch SLS, producing up to 2 million pounds of combined thrust. All RS-25 engines for Artemis missions are tested and proven flightworthy at NASA Stennis prior to use. RS-25 tests are conducted by a team of operators from NASA, L3Harris, and Syncom Space Services, prime contractor for site facilities and operations.

Pierre began his research as a theoretical physicist. His doctoral thesis examined the existence and properties of a condensed superfluid state of liquid Helium 3 at very low temperature. He lectured on basic physics, geophysical fluid dynamics, and climate science. As his career progressed, he focused his research on studying the circulation of the atmosphere. He was devoted to the development of numerical modelling of atmospheric flow that laid the groundwork for the study of climatology. Pierre’s work played an integral role in the development of tools used to study the atmosphere, many of which are still active today. Examples include Project Éole – an experimental wind energy plant conceived in the 1980s and created in Quebec, Canada that closed down in 1993; the ARGOS satellite, a collaboration between the Centre National d’Études Spatiale (CNES) [French Space Agency], National Oceanic and Atmospheric Administration (NOAA), and NASA, to collect and relay meteorological and oceanographic data around the world that launched in 1978; the Search and Rescue Satellite Aided Tracking (SARSAT) system, which was developed by the U.S. – specifically NOAA, NASA, and the U.S. Coast Guard and Air Force – Canada, and France, with the first satellite launch in 1982; and the European Organization for the Exploitation of Meteorological Satellites’ METEOSAT series of geostationary satellites, which launched in 1977 and remain active today. The launch of Meteosat–12 in 2022 was the first METEOSAT Third Generation (MTG) launch. Early in his career, Pierre was the director of the French Laboratoire de Météorologie Dynamique (LMD) before he became the director of the Centre National d’Études Spatiales (CNES). In 1980 he became the first chairman of the WCRP, where he steered a broad interdisciplinary research program in global climate and Earth system science that involved the participation of atmospheric, oceanic, hydrological, and polar scientists worldwide. Pierre was later in charge of planetary programs at NASA and was involved in discussions about the future of NASA’s Earth Observing System (EOS) in the mid-to-late 1990s. As an example, the Earth Observer article, “Minutes Of The Fourteenth Earth Science Enterprise/Earth Observing System (ESE/EOS) Investigators Working Group Meeting,” includes a summary of a presentation Pierre gave that focused on flight mission planning for the EOS “second series,” which was NASA’s plan at the time although ultimately not pursued, with the “first series” (i.e., Terra, Aqua, Aura) enduring much longer than anticipated. Pierre was the recipient of the 2008 Alfred Wegener Medal & Honorary Membership for his outstanding contributions to geophysical fluid dynamics, his leadership in the development of climate research, and the applications of space observation to meteorology and the Earth system science.

Explore This Section Earth Home Earth Observer Home Editor’s Corner Feature Articles Meeting Summaries News Science in the News Calendars In Memoriam More Archives 35 min read Summary of the Joint NASA LCLUC–SARI Synthesis Meeting Introduction The NASA Land-Cover and Land-Use Change (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 mapping, monitoring and modeling capabilities necessary to simulate the processes taking place and evaluate the consequences of observed and predicted changes. The South/Southeast Asia Research Initiative (SARI) has a similar goal for South/Southeast Asia, as it seeks to develop innovative regional research, education, and capacity building programs involving state-of-the-art remote sensing, natural sciences, engineering, and social sciences to enrich land use/cover change (LUCC) science in South/Southeast Asia. Thus it makes sense for these two entities to periodically meet jointly to discuss their endeavors. The latest of these joint meetings took place January 1–February 2, 2024, in Hanoi, Vietnam. A total of 85 participants attended the three-day, in-person meeting—see Photo. A total of 85 participants attended the three-day, in-person meeting. The attendees represented multiple international institutions, including NASA (Headquarters and Centers), the University of Maryland, College Park (UMD), other American academic institutions, the Vietnam National Space Center (VNSC, the event host), the Vietnam National University’s University of Engineering and Technology, and Ho Chi Minh University of Technology, the Japanese National Institute of Environmental Studies (NIES), Center for Environmental Sciences, and the University of Tokyo. In addition, several international programs participated, including GEO Global Agricultural Monitoring (GEOGLAM), the System for Analysis, Research and Training (START), Global Observation of Forest and Land-use Dynamics (GOFC–GOLD), and NASA Harvest.

Photo credit: Hotel staff (Hanoi Club Hotel, Hanoi, Vietnam) Meeting Overview The purpose of the 2024 NASA LCLUC–SARI Synthesis meeting was to discuss LUCC issues – with a particular focus on their impact on Southeast Asian countries. Presenters highlighted ongoing projects aimed to advance our understanding of the spatial extent, intensity, social consequences, and impacts on the environment in South/Southeast Asian countries. While presenters reported on specific science results, they also were intentional to review and synthesize work from other related projects going on in Southeast Asia. Meeting Goal The meeting’s overarching goal was to create a comprehensive and holistic understanding of various LUCC issues by examining them from multiple angles, including: collating information; employing interdisciplinary approaches; integrating research; identifying key insights; and enhancing regional collaborations. The meeting sought to bring the investigators together to bridge gaps, promote collaborations, and advance knowledge regarding LUCC issues in the region. The meeting format also provided ample time between sessions for networking to promote coordination and collaboration among scientists and teams. Meeting and Summary Format The meeting consisted of seven sessions that focused on various LUCC issues. The summary report that follows is organized by day and then by session. All presentations in Session I and II are summarized (i.e., with all speakers, affiliations, and appropriate titles identified). The keynote presentation(s) from Sessions III–VI are summarized similarly. The technical presentations in each of these sessions are presented as narrative summaries. Session VII consisted of topical discussions to close out the meeting and summaries of these discussions are included herein. Sessions III–VI also included panel discussions, but to keep the article length more manageable, summaries of these discussions have been omitted. Readers interested in learning more about the panel discussions or viewing any of these presentations in full can access the information on the Joint LCLUC–SARI Synthesis meeting website. DAY ONE The first day of the meeting included welcoming remarks from the U.S. Ambassador to Vietnam (Session I), program executives of LCLUC and SARI, as well as from national space agencies in South and Southeast Asia (Session II), and other LCLUC-thematic/overview presentations (Session III). Session 1: Welcoming Remarks Garik Gutman [NASA Headquarters—LCLUC Program Manager], Vu Tuan [VNSC’s Vietnam Academy of Science and Technology (VAST)—Vice Director General], Chris Justice [University of Maryland, College Park (UMD)—LCLUC Program Scientist], Matsunaga Tsuneo [National Institute of Environmental Studies (NIES), Japan], and Krishna Vadrevu [NASA’s Marshall Space Flight Center—SARI Lead] delivered opening remarks that highlighted collaborations across air pollution, agriculture, forestry, urban development, and other LUCC research areas. While each of the speakers covered different topics, they emphasized common themes, including advancing new science algorithms, co-developing products, and fostering applications through capacity building and training. After the opening remarks, special guest Marc Knapper [U.S. Ambassador to Vietnam] gave a presentation in which he emphasized the value of collaborative research between U.S. and Vietnamese scientists to address environmental challenges – especially climate change and LUCC issues. He expressed appreciation to the meeting organizers for promoting these collaborations and highlighted the joint initiatives between NASA and the U.S. Agency for International Development (USAID) to monitor environmental health and climate change, develop policies to reduce emissions, and support adaptation in agriculture. The U.S.–Vietnam Comprehensive Strategic Partnership emphasizes the commitment to address climate challenges and advance bilateral research. He concluded by encouraging active participation from all attendees and stressed the need for ongoing international collaboration to develop effective LUCC policies. Session-II: Programmatic and Space Agency Presentations NOTE: Other than Ambassador Knapper, the presenters in Session I gave welcoming remarks and programmatic and/or space agency presentations in Session II,. Garik Gutman began the second session by presenting an overview of the LCLUC program, which aims to enhance understanding of LUCC dynamics and environmental implications by integrating diverse data sources (i.e., satellite remote sensing) with socioeconomic and ecological datasets for a comprehensive view of land-use change drivers and consequences. Over the past 25 years, LCLUC has funded over 325 projects involving more than 800 researchers, resulting in over 1500 publications. The program’s focus balances project distribution that spans detection and monitoring, and impacts and consequences, including drivers, modeling, and synthesis. Gutman highlighted examples of population growth and urban expansion in Southeast Asia, resulting in environmental and socio-economic impacts. Urbanization accelerates deforestation, shifts farming practices to higher-value crops, and contributes to the loss of wetlands. This transformation alters the carbon cycle, degrades air quality, and increases flooding risks due to reduced rainwater absorption. Multi-source remote sensing data and social dimensions are essential in addressing LUCC issues, and the program aims to foster international collaborations and capacity building in land-change science through partnerships and training initiatives. (To learn more about the recent activities of the LCLUC Science Team, see Summary of the 2024 Land Cover Land Use Change Science Team Meeting.) Krishna Vadrevu explained how SARI connects regional and national projects with researchers from the U.S. and local institutions to advance LUCC mapping, monitoring, and impact assessments through shared methodologies and data. The initiative has spurred extensive activities, including meetings, training sessions, publications, collaborations, and fieldwork. To date, the LCLUC program has funded 35 SARI projects and helped build collaborations with space agencies, universities, and decision-makers worldwide. SARI Principal Investigators have documented notable land-cover and land-use transformations, observing shifts in land conversion practices across Asia. For example, the transition from traditional slash-and-burn practices for subsistence agriculture to industrial oil palm and rubber plantations in Southeast Asia. Rapid urbanization has also reshaped several South and Southeast Asian regions, expanding both horizontally in rural areas and vertically in urban centers. The current SARI solicitation funds three projects across Asia, integrating the latest remote sensing data and methods to map, monitor, and assess LUCC drivers and impacts to support policy-making. Vu Tuan provided a comprehensive overview of Vietnam’s advances in satellite technology and Earth observation capabilities, particularly through the LOTUSat-1 satellite (name derived from the “Lotus” flower), which is equipped with an advanced X-band Synthetic Aperture Radar (SAR) sensor capable of providing high-resolution imagery [ranging from 1–16 m (3–52 ft)]. This satellite is integral to Vietnam’s efforts to enhance disaster management and climate change mitigation, as well as to support a range of applications in topography, agriculture, forestry, and water management, as well as in oceanography and environmental monitoring. The VNSC’s efforts are part of a broader strategy to build national expertise and self-reliance in satellite technology, such as developing a range of small satellites (e.g., NanoDragon, PicoDragon, and MicroDragon) that progress in size and capability. Alongside satellite development, the VNSC has established key infrastructure, facilities, and capacity building in Hanoi, Nha Trang, and Ho Chi Minh City to support satellite assembly, integration, testing, and operation. Tuan showcased the application of remotely sensed LUCC data to map and monitor urban expansion in Ha Long city from 2000–2023 and the policies needed to manage these changes sustainably – see Figure 1. Figure 1. Urban expansion area in Ha Long City, Vietnam from 2000–2023 from multidate Landsat satellite imagery. Figure credit: Vu Tuan [VNSC] Tsuneo Matsunaga provided a detailed overview of Japan’s Greenhouse Gases Observing Satellite (GOSAT) series of satellites, data from which provide valuable insights into global greenhouse gas (GHG) trends and support international climate agreements, including the Paris Agreement. Matsunaga reviewed the first two satellites in the series: GOSAT and GOSAT-2, then previewed the next satellite in the series: GOSAT-GW, which is scheduled to launch in 2025. GOSAT-GW will fly the Total Anthropogenic and Natural Emissions Mapping Observatory–3 (TANSO-3) – an improved version of TANSO-2, which flies on GOSAT-2. TANSO-3 includes a Fourier Transform Spectrometer (FTS-3) that has improved spatial resolution [10.5 km (6.5 mi)] over TANSO-FTS-2 and precision that matches or exceeds that of its predecessor. TANSO-FTS-3 will allow estimates with precision better than 1 ppm for carbon dioxide (CO2) and 10 ppb for methane (CH4), as well as enabling nitrogen dioxide (NO2) measurements. GOSAT–GW will also fly the Advanced Microwave Scanning Radiometer (AMSR3) that will monitor water cycle components (e.g., precipitation, soil moisture) and ocean surface winds. AMSR3 builds on the heritage of three previous AMSR instruments that have flown on NASA and Japan Aerospace Exploration Agency (JAXA) missions. Matsunaga also highlighted the importance of ground-based validation networks, such as the Total Carbon Column Observing Network, COllaborative Carbon Column Observing Network, and the Pandora Global Network, to ensure satellite data accuracy. Son Nghiem [NASA/Jet Propulsion Laboratory (JPL)] addressed dynamic LUCC in Cambodia, Laos, Thailand, Vietnam, and Malaysia. The synthesis study examined the factors that evolve along the rural–urban continuum (RUC). Nghiem showcased this effort using Synthetic Aperture Radar (SAR) data from the Copernicus Sentinel-1 mission to map a typical RUC in Bac Lieu, Vietnam – see Figure 2. Figure 2. Land cover map of Bae Lieu, Vietnam, and surrounding rural areas. The image shows persistent building structures (red), agricultural areas (light green), aquacultural (light blue), tree cover (dark green), and water bodies (dark blue). Land-use classes used on this map are derived from Sentinel-1 Synthetic Aperture Radar (SAR) for the rural urban continuum around Bac Lieu. Figure credit: Son Nghiem [JPL] Nghiem described the study, which examined the role of rapid urbanization, agricultural conversion, climate change, and environment–human feedback processes in causing non-stationary and unpredictable impacts. This work illustrates how traditional trend analysis is insufficient for future planning. The study also examined whether slower or more gradual changes could inform policy development. To test these hypotheses, his research will integrate high-resolution radar and hyperspectral data with socioeconomic analyses. The study highlights the need for policies that are flexible and responsive to the unique challenges of different areas, particularly in “hot-spot” regions experiencing rapid changes. Peilei Fan [Tufts University] presented a study that synthesizes the complex patterns of LUCC, identifying both the spatial and temporal dynamics that characterize transitions in urban systems. The study explores key drivers, including economic development, population growth, urbanization, agricultural expansion, and policy shifts. She emphasized the importance of understanding these drivers for sustainable land management and urban planning. For example, the Yangon region of Myanmar has undergone rapid urbanization – see Figure 3. Her work reveals the need for integrated approaches that consider both urban and rural perspectives to manage land resources effectively and mitigate negative environmental and social impacts. Through a combination of case studies, statistical analysis, and policy review, Fan and her team aim to provide a nuanced understanding of the interactions between human activities and environmental changes occurring in the rapidly transforming landscapes of Southeast Asia. Figure 3. Landsat data can be used to track land cover change over time. For example, Thematic Mapper data have been used to track urban expansion around Yangon, Myanmar. The data show that the built-up area expanded from 161 km2 (62 mi2) in 1990 to 739 km2 (285 mi2) in 2020. Figure credit: Peleli Fan [Tufts University] Session III: Land Cover/Land Use Change Studies Tanapat Tanaratkaittikul [Geo-Informatics and Space Technology Development Agency (GISTDA), Thailand] highlighted GISTDA activities, which play a crucial role in advancing Thailand’s technological capabilities and addressing both national and global challenges, including Thailand Earth Observation System (THEOS) and its successors: THEOS-2 and THEOS-2A. THEOS-1, which launched in 2008, provides 2-m (6-ft) panchromatic and 15-m (45-ft) multispectral resolution with a 26-day revisit cycle, which can be reduced to 3 days with off-nadir pointing. Launched in 2023, THEOS-2 includes two satellites – THEOS-2A [a very high-resolution satellite with 0.5-m (1.5-ft) panchromatic and 2-m (6-ft) multispectral imagery] and THEOS-2B [a high-resolution satellite with 4-m (12-ft) multispectral resolution] – with a five-day revisit cycle. GISTDA also develops geospatial applications for drought assessment, flood prediction, and carbon credit calculations to support government decision-making and climate initiatives. GISTDA partners with international collaborators on regional projects, such as the Lancang-Mekong Cooperation Special Fund Project. Eric Vermote [NASA’s Goddard Space Flight Center] presented a keynote that focused on atmospheric correction of land remote sensing data and related algorithm updates. He highlighted the necessity of correcting surface imaging for atmospheric effects, such as molecular scattering, aerosol scattering, and gaseous absorption, which can significantly distort the satellite spectral signals and lead to potential errors in applications, such as land cover mapping, vegetation monitoring, and climate change studies. Vermote explained that the surface reflectance algorithm uses precise vector radiative transfer modeling to improve accuracy by incorporating atmospheric parameter inversion. It also adjusts for various atmospheric conditions and aerosol types – enhancing corrections across regions and seasons. He explained that SkyCam – a network of ground-based cameras – provides real-time assessments of cloud cover that can be used to validate cloud masks, while the Cloud and Aerosol Measurement System (CAMSIS) offers additional ground validation by measuring atmospheric conditions. He said that together, SkyCam and CAMSIS improve satellite-derived cloud masks, supporting more accurate climate models and environmental monitoring. Vermote’s work highlights the ongoing advancement of atmospheric correction methods in remote sensing. Other presentations in this session included one in which the speaker described how Yangon, the capital city in Myanmar, is undergoing rapid urbanization and industrial growth. From 1990–2020, the urban area expanded by over 225% – largely at the expense of agricultural and green lands. Twenty-nine industrial zones cover about 10.92% of the city, which have attracted significant foreign direct investment, particularly in labor-intensive sectors. This growth has led to challenges with land confiscations, inadequate infrastructure, and environmental issues (e.g., air pollution). Additionally, rural migration for employment has resulted in informal settlements, emphasizing the need for comprehensive urban planning that balances economic development with social equity and sustainability. Another presentation highlighted varying LUCC trends across Vietnam. In the Northern and Central Coastal Uplands, for example, swidden systems are shifting toward permanent tree crops, such as rubber and coffee. Meanwhile, the Red River Delta is seeing urban densification and consolidation of farmland – transitioning from rice to mixed farming with increased fruit and flower production. Similarly, the Central Coastal Lowlands and Southeastern regions are experiencing urban growth and a shift from coastal agriculture – in this case, to shrimp farming – leading to mangrove loss. The Central Highlands is moving from swidden to tree crops, particularly fruit trees, while the Mekong River Delta is increasing rice cropping and aquaculture. These changes contribute to urbanization, altered farming practices, and biodiversity loss. Advanced algorithms (e.g., the Time-Feature Convolutional Neural Network model) are being used to effectively map these varied LUCC changes in Vietnam. Another presenter explained how 10-m (33-ft) resolution spatially gridded population datasets are essential to address LUCC in environmental and socio-demographic research. There was also a demonstration of PopGrid, which is a collaborative initiative that provides access to various global-gridded population databases, which are valuable for regional LUCC studies and can support informed decision-making and policy development. DAY TWO The second day’s presentations centered around urban LUCC (Session IV) as well as interconnections between agriculture and water resources. (Session V). Session IV: Urban Land Cover/Land Use Change Gay Perez [Philippines Remote Sensing Agency (PhilSA)] presented a keynote focused on PhilSA’s mission to advance Philippines as a space-capable country by developing indigenous satellite and launch technologies. He explained that PhilSA provides satellite data in various categories, including sovereign, commercial, open-access, and disaster-activated. He noted that the ground infrastructure – which includes three stations and a new facility in Quezon – supports efficient data processing. For example, Perez stated that in 2023, PhilSA produced over 10,000 maps for disaster relief, agricultural assessments, and conservation planning. Perez reviewed PhilSA’s Diwata-2 mission, which launched in 2018 and operates in a Sun-synchronous orbit around 620 km (385 mi) above Earth. With a 10-day revisit capability, it features a high-precision telescope [4.7 m (15ft) resolution], a multispectral imager with four bands, an enhanced resolution camera, and a wide-field camera. Since launch, Diwata-2 has captured over 100,000 global images, covering 95% of the Philippines. Looking to the near future, Perez reported that PhilSA’s launch of the Multispectral Unit for Land Assessment (MULA) satellite is planned for 2025. He explained that MULA will capture images with a 5-m (~16-ft) resolution and 10–20-day revisit time, featuring 10 spectral bands for vegetation, water, and urban analysis. Perez also described the Drought and Crop Assessment and Forecasting project, which addresses drought risks and mapping ground motion in areas, e.g., Baguio City and Pangasinan. Through partnerships in the Pan-Asia Partnership for Geospatial Air Pollution Information (PAPGAPI) and the Pandora Asia Network, PhilSA monitors air quality across key locations, tracking urban pollution and cross-border particulate transport. PhilSA continues to strengthen Southeast Asian partnerships to drive sustainable development in the region. Jiquan Chen [Michigan State University] presented the second keynote address, which focused on the Urban Rural Continuum (URC). Chen emphasized the importance of synthesizing studies that explore factors such as population dynamics, living standards, and economic development in the URC. Key considerations include differentiating between two- and three-dimensional infrastructures and understanding constraints from historical contexts. Chen highlighted critical variables from his analysis including net primary productivity, household income, and essential infrastructure elements, such as transportation and healthcare systems. He advocated for integrated models that combine mechanistic and empirical approaches to grasp the dynamics of URC changes, stressing their implications for urban planning, environmental sustainability, and social equity. He concluded with a call for collaboration to enhance these models and tackle challenges arising from the changing urban–rural landscape. Tep Makathy [Cambodian Institute For Urban Studies] discussed urbanization in Phnom Penh, Cambodia. He explained that significant LUCC and infrastructure developments have been fueled by direct foreign investment; however, this development has resulted in environmental degradation, urban flooding, and infrastructure strain. Tackling pollution, congestion, preservation of green spaces, and preserving the historical heritage of the city will require sustainable urban planning efforts. Nguyen Thi Thuy Hang [Vietnam Japan University, Vietnam National University, Hanoi] explained how flooding poses a significant annual threat to infrastructure and livelihoods in Can Tho, Vietnam. Therefore, it is essential to incorporate climate change considerations into land-use planning by enhancing the accuracy of vegetation layer classifications. Doing so will improve the representation of land-cover dynamics in models that decision-makers use when planning urban development. In addition, Hang reported that a more comprehensive survey of dyke systems will improve flood protection and identify areas needing reinforcement or redesign. These studies could also explore salinity intrusion in coastal agricultural areas that could impact crop yields and endanger food security. In this session, two presenters highlighted how SAR data, which uses high backscatter to enhance the radar signal, is being used to assist with mapping urban areas in their respective countries. The phase stability and orientation of building structures across SAR images aid in consistent monitoring and backscatter, producing distinct image textures specific to urban settings. Researchers can use this heterogeneity and texture to map urban footprints, enabling automated discrimination between urban and non-urban areas. The first presenters showed how Interferometric Synthetic Aperture Radar techniques, such as Small Baseline Subset (SBAS) and Persistent Scatterer (PS) have been highly effective for mapping and monitoring land subsidence in coastal and urban areas in Vietnam. This approach has been applied to areas along the Saigon River as well as in Ho Chi Minh, Vietnam. The second presenter described an approach (using SAR data with multitemporal coherence and the K-means classification method) that has been used effectively to study urban growth in the Denpasar Greater Area of Indonesia between 2016 and 2022. The technique identified the conversion of 4376 km2 (1690 mi2) of rural to built-up areas, averaging 72.9 hectares (0.3 mi2) per year. Urban sprawl was predominantly observed in the North Kuta District, where the shift from agricultural to built-up land use has been accompanied by severe traffic congestion and other environmental issues. Another presenter showed how data from the QuikSCAT instrument, which flew on the Quick Scatterometer satellite, and from the Sentinel-1 C-band SAR can be combined to measure and analyze urban built-up volume, specifically focusing on the vertical growth of buildings across various cities. By integrating these datasets, researchers can assess urban expansion, monitor the development of high-rise buildings, and evaluate the impact of urbanization on infrastructure and land use. This information is essential for urban planning, helping city planners and policymakers make informed decisions to accommodate growing populations and enhance sustainable urban development. Session V – LUCC, Agriculture, and Water Resources Chris Justice presented the keynote for this session, in which he addressed the GEOGLAM initiative and the NASA Harvest program. GEOGLAM, initiated by the G20 Agriculture Ministers in 2011, focuses on agriculture and food security to increase market transparency and improve food security. These efforts leverage satellite-based Earth observations to produce and disseminate timely, relevant, and actionable information about agricultural conditions at national, regional, and global scales to support agricultural markets and provide early warnings for proactive responses to emerging food emergencies. NASA Harvest uses satellite Earth observations to benefit global food security, sustainability, and agriculture for disaster response, climate risk assessments, and policy support. Justice also emphasized the use of open science and open data principles, promoting the integration of Earth observation data into national and international agricultural monitoring systems. He also discussed the development and application of essential agricultural variables, in situ data requirements, and the need for comprehensive and accurate satellite data products. During this session, another presentation focused on how VNSC is engaged in several agricultural projects, including mapping rice crops, estimating yields, and assessing environmental impacts. VNSC has created high-accuracy rice maps for different seasons that the Vietnamese government uses to monitor and manage agricultural production. Current initiatives involve using satellite data to estimate CH4 emissions from rice paddies, biomass mapping, and monitoring rice straw burning. For example, in the Mekong Delta, numerous environmental factors, including climate change-induced stress (e.g., sea-level rise), flooding, drought, land subsidence, and saltwater intrusion, along with human activities like dam construction, sand mining, and groundwater extraction, threaten the sustainability of rice farming and farmer livelihoods. To address these challenges, sustainable agricultural practices are essential to improving rice quality, diversify farming systems, adopt low-carbon techniques, and enhance water management. Presentations highlighted the importance of both optical and SAR data for LUCC studies, particularly in mapping agricultural areas. A study using Landsat time-series data demonstrated its value in monitoring agricultural LUCC in Houa Phan Province, Laos, and Son La Province, Vietnam. Land cover types were classified through spectral pattern analysis, identifying distinct classes based on Landsat reflectance values. The findings revealed significant natural forest loss alongside increases in cropland and forest plantations due to agricultural expansion. High-resolution imagery validated these results, indicating the scalability of this approach for broader regional and global land-cover monitoring. Another study showcased the effectiveness of SAR data from the Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) on the Japanese Advanced Land Observing Satellite-2 (ALOS-2) for mapping and monitoring agricultural land use in Suphanburi, Thailand. This data proved particularly useful for capturing seasonal variations and diverse agricultural practices. Supervised machine learning methods, such as Random Forest classifiers, combined with innovative spatial averaging techniques, achieved high accuracy in distinguishing various agricultural conditions. In the session, presenters also discussed the use of Sentinel-1 SAR data for mapping submerged and non-submerged paddy soils was highlighted, demonstrating its effectiveness in understanding water management issues see – Figure 4. Additionally, large-scale remote sensing data and cloud computing were shown to provide unprecedented opportunities for tracking agricultural land-use changes in greater detail. Case studies from India and China illustrated key challenges, such as groundwater depletion in irrigated agriculture across the Indo-Ganges region and the impacts on food, water, and air quality in both countries. Figure 4. Series of Sentinel-1 radar data images showing submerged paddy soil (blue) and non-submerged paddy soil (red) in the Mekong Delta, Vietnam. Figure credit: Hiranori Arai [International Rice Research Institute] The session also focused on Water–Energy–Food (WEF) issues related to the Mekong River Basin’s extensive network of hydroelectric dams, which present both benefits and challenges. While these dams support sectors such as irrigated agriculture and hydropower, they also disrupt vital ecosystem services, including fish habitats and biodiversity. Collaborative studies integrating satellite and ground data, hydrological models, and socio-economic frameworks highlight the need to balance these benefits with ecological and social costs. Achieving sustainable management requires cross-sectoral and cross-border cooperation, as well as the incorporation of traditional knowledge to address WEF trade-offs and governance challenges in the region. DAY THREE The third day included a session that explored the impacts of fire, GHG emissions, and pollution (Session VI) as well as a summary discussion on synthesis (Session VII). Session VI: Fires, Greenhouse Gas Emissions, and Pollution Chris Elvidge [Colorado School of Mines] presented a keynote on the capabilities and applications of the Visible Infrared Imaging Radiometer Suite (VIIRS) Nightfire [VNF] system, an advanced satellite-based tool developed by the Earth Observation Group. VIIRS Nightfire uses four near- and short-wave infrared channels, initially designed for daytime imaging, to detect and monitor infrared emissions at night. The system identifies various combustion sources, including both flaming and non-flaming activities (e.g., biomass burning, gas flaring, and industrial processes). It calculates the temperature, source area, and radiant heat of detected infrared emitters using physical laws to enable precise monitoring of combustion events and provide insight into exothermic and endothermic processes. Elvidge explained that VNF has been vital for near-real-time data in Southeast Asia. The system has been used to issue daily alerts for Vietnam, Thailand, and Indonesia. Recent updates in Version 4 (V4) include atmospheric corrections and testing for secondary emitters with algorithmic improvements – with a 50% success rate in identifying additional heat sources. The Earth Observation Group maintains a multiyear catalog of over 20,000 industrial infrared emitters available through the Global Infrared Emitter Explorer (GIREE) web-map service. With VIIRS sensors expected to operate until about 2040 on the Joint Polar Satellite System (JPSS) platforms, this system ensures long-term, robust monitoring and analysis of global combustion events, proving essential for tracking the environmental impacts of industrial activities and natural combustion processes on the atmosphere and ecosystems. Toshimasa Ohara [Center for Environmental Science, Japan—Research Director] continued with the second keynote and provided an in-depth analysis of long-term trends in anthropogenic emissions across Asia. The regional mission inventory in Asia encompasses a range of pollutants and offers detailed emissions data from 1950–2020 at high spatial and temporal resolutions. The study employs both bottom-up and top-down approaches for estimating emissions, integrating satellite observations to validate data and address uncertainties. Notably, emissions from China, India, and Japan have shown signs of stabilization or reduction, attributed to stricter emission control policies and technological advancements. Ohara also highlighted Japan’s effective air pollution measures and the importance of extensive observational data in corroborating emission trends. His presentation emphasized the need for improved methodologies in emission inventory development and validation across Asia, aiming to enhance policymaking and environmental management in rapidly industrializing regions. Several presenters during this session focused on innovative approaches to understand and mitigate GHG emissions and air pollution. One presenter showed how NO2 data from the TROPOspheric Monitoring Instrument (TROPOMI) on the European Sentinel-5 Precursor have been validated against ground-based observations from Pandora stations in Japan, highlighting the influence of atmospheric conditions on measurement accuracy. Another presenter described an innovative system that GISTDA used to combine satellite remote sensing data with Artificial Intelligence (AI). This system was used to monitor and analyze the concentration of fine particulate matter (PM) in the atmosphere in Thailand. (In this context fine is defined as particles with diameters ≤ 2.5 µm, or PM2.5.) These applications, which are accessible through online, cloud-based platforms and mobile applications for iOS and Android devices, allow users, including citizens, government officers, and policymakers, to access PM2.5 data in real-time through web and mobile interfaces. A project under the United Nations Economic and Social Commission for Asia and the Pacific in Thailand is focused on improving air quality monitoring across the Asia–Pacific region by integrating satellite and ground-based data. At the core of this effort, the Pandora Asia Network, which includes 30 ground-based instruments measuring pollutants such as NO₂ and sulfur dioxide (SO₂), is complemented by high-resolution observations from the Geostationary Environment Monitoring Spectrometer (GEMS) aboard South Korea’s GEO-KOMPSAT-2B (GK-2B) satellite. The initiative also provides training sessions to strengthen regional expertise in remote sensing technologies for air quality management and develops decision support systems for evidence-based policymaking, particularly for monitoring pollution sources and transboundary effects like volcanic eruptions. Future plans include expanding the Pandora network and enhancing data integration to support local environmental management practices. PM2.5 levels in Vietnam are influenced by both local emissions and long-range pollutant transport, particularly in urban areas.The Vietnam University of Engineering and Technology, in conjunction with VNSC, continues to map and monitor PM2.5 using satellites and machine learning while addressing data quality issues that stem from missing satellite data and limited ground monitoring stations – see Figure 5. In addition to mapping and monitoring pollutants, another presentater explained that significant research is underway to address their health impacts. In Hanoi, exposure to pollutants ( e.g., PM2.5, PM10, and NO2) has led to increased rates of respiratory diseases (e.g., pneumonia, bronchitis, and asthma) among children, as well as elevated instances of cardiovascular diseases among adults. A substantial mortality burden is attributable to fine particulate matter – particularly in densely populated areas like Hanoi. Compliance with stricter air quality guidelines could potentially prevent thousands of premature deaths. For example, preventive measures enacted during the COVID-19 pandemic resulted in reduced pollution levels that were associated with a decrease in avoidable mortality rates. In response to these challenges, Vietnam has implemented air quality management policies, including national technical regulations and action plans aimed at controlling emissions and enhancing monitoring; however, current national standards still fall short of the more stringent guidelines recommended by the World Health Organization. Improved air quality standards and effective policy interventions are needed to mitigate the health risks associated with air pollution in Vietnam. Figure 5. Map of particulate matter (PM 2.5) variations observed across Vietnam, using multisatellite aerosol optical depth (AOD) data from the Moderate Resolution Imaging Spectrogradiometer (MODIS) on NASA’s Aqua and Terra platforms, and from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NASA–NOAA Suomi NPP platform, combined with ground-based AOD and meteorological data. Figure credit: Thanh Nguyen [Vietnam National University of Engineering and Technology, Vietnam] Another presenter explained how food production in Southeast Asia contributes about 40% of the region’s total GHG emissions – with rice and beef production identified as the largest contributors for plant-based and animal-based emissions, respectively. Another presentation focused on a study that examined GHG emissions from agricultural activities, which suggests that animal-based food production – particularly beef – generates substantially higher GHG emissions per kg of food produced compared to plant-based foods, such as wheat and rice. Beef has an emission intensity of about 69 kg of CO2 equivalent-per-kg, compared to 2 to 3 kg of CO2 equivalent-per-kg for plant-based foods. The study points to mitigation strategies (e.g., changing dietary patterns, improving agricultural practices) and adopting sustainable land management. Participants agreed that a comprehensive policy framework is needed to address the environmental impacts of food production and reduce GHG emissions in the agricultural sector. In another presentation, the speaker highlighted the fact that Southeast Asian countries need an advanced monitoring, reporting, and verification system to track GHG emissions – particularly within high-carbon reservoirs like rice paddies. To achieve this, cutting-edge technologies (e.g., satellite remote sensing, low-cost unmanned aerial vehicles, and Internet of Things devices) can be beneficial in creating sophisticated digital twin technology for sustainable rice production and GHG mitigation. Another presentation featured a discussion about pollution resulting from forest and peatland fires in Indonesia, which is significantly impacting air quality. Indonesia’s tropical peatlands – among the world’s largest and most diverse – face significant threats from frequent fires. Repeated burning has transformed forests into shrubs and secondary vegetation regions, with fires particularly affecting forest edges and contributing to a further retreat of intact forest areas. High-resolution data is essential to map and monitor changes in forest cover, including pollution impacts. Another speaker described a web-based Geographic Information Systems (GIS) application that has been developed to support carbon offsetting efforts in Laos – to address significant environmental challenges, e.g., deforestation and climate change. Advanced technologies (e.g., remote sensing, GIS, and Global Navigation Satellite Systems) are used to monitor land-use changes, carbon sequestration, and ecosystem health. By integrating various spatial datasets, the web GIS app enhances data collection precision, streamlines monitoring processes, and provides real-time information to stakeholders for informed decision-making. This initiative fosters collaboration among local communities, government agencies, and international partners, while emphasizing the importance of government support and international partnerships. Ultimately, the web GIS application represents a significant advancement in Laos’s commitment to environmental sustainability, economic growth, and the creation of a greener future. Session VII. Discussion Session on Synthesis The meeting concluded with a comprehensive discussion on synthesizing themes related to LUCC. The session focused on three themes: LUCC, agriculture, and air pollution. The session focused on trends and projections as well as the resulting impacts in the coming years. It also highlighted research related to these topics to inform more sustainable land use policies. A panel of experts from different Southeast Asian countries addressed these topics. A summary of the key points shared by the panelists for each theme during the discussion is provided below. LUCC Discussions This discussion focused on the challenges of balancing economic development with environmental sustainability in Southeast Asian countries, e.g., mining in Myanmar, agriculture in Vietnam, and rising land prices in Thailand. More LUCC research is needed to inform decision-making and improve land-use planning during transitions from agriculture to industrialization while ensuring food security. The panelists also discussed urban sprawl and infrastructure development along main roads in several Southeast Asian countries, highlighting the social and environmental challenges arising from uncoordinated growth. It was noted that urban infrastructure lags behind population increases, resulting in traffic congestion, pollution, and social inequality. Cambodia, for example, has increased foreign investments, which presents similar dilemmas of economic growth accompanied by significant environmental degradation. Indonesia is another example of a Southeast Asian nation facing rapid urbanization and inadequate spatial planning, leading to flooding, groundwater depletion, and pollution. These issues further highlight the need for integrated satellite monitoring to inform land-use policies. Finally, recognizing the importance of public infrastructure in growth management, it was reported that the Thai government is already using technology to manage urban development alongside green spaces. Panelists agreed that LUCC research is critical for guiding policymakers toward sustainable land-use practices – emphasizing the necessity for improved communication between researchers and policymakers. While the integration of technologies (e.g., GIS and remote sensing) is beginning to influence policy decisions, room for improvement remains. In summary, the discussions stressed the importance of better planning, technology integration, and policy-informed research to reconcile economic growth with sustainability. Participants also highlighted the need to engage policymakers, non-government organizations, and the private sector in using scientific evidence for sustainable development. Capacity building in Laos, Cambodia, and Myanmar, where GIS and remote sensing technologies are still developing, is crucial. Community involvement is essential for translating research findings into actionable policies to address real-world challenges and social equity. Agriculture Discussions These discussions explored the intricate relationships between agricultural practices, economic growth, and environmental sustainability in Southeast Asia. As an example, despite national policies to manage the land transition in Vietnam, rapid conversions from forest to agricultural land and further to residential and industrial continue. While it is recognized that strict land management plans may hinder future adaptability, further regulation is needed. These rapid shifts in land use have increased land for economic development – especially in industrial and residential sectors – and contribute to environmental degradation, e.g., pollution and soil erosion. In Thailand, land is distributed among agriculture (50%), forest (30%), and urban (20%) areas. Despite a long history of agricultural practices, Vietnam faces new challenges from climate change and extreme weather. Thailand, meanwhile, is exploring carbon credits to incentivize sustainable farming practices – although this requires significant investment and time. The nation is well-equipped with a robust water supply system, and ongoing efforts to enhance crop yields on Vietnam’s Mekong Delta, salinity levels, and flooding intensity have increased as a result of the rise in incidents of extreme weather, prompting advancements in rice farming mechanization to be implemented that are modeled after practices that have been successfully used in the Philippines. Despite these advances, issues (e.g., over-application of rice seeds) remain. The dominant land cover type in Malaysia is tropical rainforest, although agriculture – particularly oil palm plantations – also plays a significant role in land use. While stable, it shares environmental concerns with Indonesia. The country is integrating solar energy initiatives, placing solar panels on former agricultural lands and recreational areas, which raises coastal environmental concerns. In Taiwan, substantial land use changes have stemmed from solar panel installations to support green energy goals but have led to increased temperatures and altered wind patterns. All panelists agreed that remote sensing technologies are vital to inform agricultural policy across the region. They emphasized the need to transition from academic research to actionable insights that directly inform policy. Panelists also discussed the challenge of securing funding for actionable research – underlining the importance of recognizing the transition required for research to inform operational use. Some countries (e.g., Thailand) have established operational crop monitoring systems, while others (e.g., Vietnam) primarily depend on research projects. Despite progress in Malaysia’s monitoring of oil palm plantations, a comprehensive operational monitoring system is still lacking in many areas. The participants concluded that increased efforts are needed to promote the wider adoption of remote sensing technologies for agricultural and environmental monitoring, with emphasis on developing operational systems that can be integrated into policy and decision-making processes. Air Pollution Discussions The discussion on air pollution focused on various sources in Southeast Asia, which included both local and transboundary factors. Panelists highlighted that motor vehicles, industrial activities, and power plants are major contributors to pollutants, such as PM2.5, NO2, ozone (O3), and carbon monoxide (CO). Forest fires in Indonesia – particularly from South Sumatra and Riau provinces – are significantly impacting neighboring countries, e.g., Malaysia. A study found that most PM2.5 pollution in Kuala Lumpur originates from Indonesia. During the COVID-19 pandemic, pollution levels dropped sharply due to reduced economic activity; however, data from 2018–2023 shows that PM2.5 levels have returned to pre-pandemic conditions. The Indonesian government is actively working to reduce deforestation and emissions, aiming for a 29% reduction by 2030. Indonesia is also participating in carbon markets and receiving international payments for emission reductions. Indonesia’s emissions also stem from energy production, industrial activities, and land-use changes, including peat fires. The Indonesian government reports anthropogenic sources – particularly from the energy sector and industrial activities, forest and peat fires, waste, and agriculture – continue to escalate. While Indonesia is addressing these issues, growing population and energy demands continue to drive pollution levels higher. Vietnam and Laos are facing similar challenges related to air pollution – particularly from agricultural residue burning. Both governments are working on expanding air quality monitoring, regulating waste burning, and developing policies to mitigate pollution. Vietnam has been developing provincial air quality management plans and expanding its monitoring network. Laos has seen increased awareness of pollution, accompanied by government measures aimed at restricting burning and improving waste management practices. The panelists agreed that collaborative efforts for regional cooperation are essential to address air pollution. This will require collaboration in research and data sharing to inform policy decisions. There is a growing interest in leveraging satellite technology and modeling approaches to enhance air quality forecasting and management. To ensure that research translates into effective policy, communication of scientific findings to policymakers is essential – particularly by clearly communicating complex research concepts in accessible formats. All panelists agreed on the importance of improving governance, transparency, and scientific communication to better translate research into policy actions, highlighting collaborations with international organizations – including NASA – to address air quality issues. While significant challenges related to air pollution persist in Southeast Asia, noteworthy efforts are underway to improve awareness, research, and collaborative governance aimed at enhancing air quality and reducing emissions. Conclusion The LCLUC–SARI Synthesis meeting fostered collaboration among researchers and provided valuable updates on recent developments in LUCC research, exchange of ideas, integration of new data products, and discussions on emerging science directions. This structured dialogue (particularly the discussions in each session) helped the attendees identify priorities and needs within the LUCC community. All panelists and meeting participants commended the SARI leadership for their proactive role in facilitating collaborations and discussions that promote capacity-building activities across the region. SARI activities have significantly contributed to enhancing the collective ability of countries in South and Southeast Asia to address pressing environmental challenges. The meeting participants emphasized the importance of maintaining and expanding these collaborative efforts, which are crucial for fostering partnerships among governments, research institutions, and local communities. They urged SARI to continue organizing workshops, training sessions, and knowledge-sharing platforms that can equip stakeholders with the necessary skills and resources to tackle environmental issues such as air pollution, deforestation, climate change, and sustainable land management.

One semester as a NASA Pathways intern was enough to inspire Portia Keyes to sign up for a Russian language class at college. After interning in the Johnson Space Center’s Office of Procurement, Keyes hoped to someday use her new language skills in support of the International Space Station Program. Now, 12 years later, Keyes is the deputy manager of the procurement office for the International Space Station and Commercial Low Earth Orbit Development Programs. That means she is responsible for implementing and overseeing acquisition solutions that enable the purchasing of goods and services in support of both programs. Official NASA portrait of Portia Keyes.NASA It has also given her a chance to use some of what she learned from her Russian language course. One of Keyes’ favorite NASA projects involved negotiating a contract modification with Roscosmos to secure transportation of NASA astronauts to the International Space Station via Soyuz spacecraft following the space shuttle’s retirement. “This project stands out to me both for its impact on NASA’s missions and the way it transcended political and geographical boundaries,” Keyes said. Being a part of this effort reinforced the importance of collaboration on a global scale. “It demonstrated how shared goals and values can unite people across different nations, regardless of external circumstances,” she said. “The world is more connected than we often realize.” Keyes values collaboration on a smaller scale, as well, noting that her procurement role involves working with a wide variety of subject matter experts who are passionate about their respective fields. She acknowledged that procurement staff are sometimes seen as obstructing or slowing a mission rather than enabling it, although she has overcome this challenge through effective communication with stakeholders – striving to understand their perspectives and present mutually beneficial solutions. “My commitment is to advancing NASA’s missions through the responsible management of taxpayer dollars,” she said. “Collaborating closely with my technical counterparts, I have been able to secure mission-critical services and supplies, all while adhering to regulatory, schedule, and resource constraints.” Keyes poses for a picture outside of NASA Headquarters in Washington, D.C. Image courtesy of Portia Keyes Adaptability has also been important to Keyes’ success. “Whether it’s shifting priorities due to unforeseen challenges, navigating cultural differences within international teams, or adjusting to new acquisition regulations, being flexible and open to change has allowed me to not just survive in dynamic environments, but thrive,” she said. At the same time, Keyes strives to maintain balance in the workplace. “What I have learned about myself is that I can do anything, but not everything,” she said. “Maturing in my career has meant accepting that I have limited time, energy, and resources, so it is important to discern what truly matters and focus my efforts there.” Portia Keyes, fourth from left, received a JSC Director’s Commendation Award in June 2024 for significant contributions to Johnson’s Office of Procurement. From left are Johnson Associate Director for Vision and Strategy Douglas Terrier, Office of Procurement Director Brad Niese, Office of Procurement Functional Lead Candice Palacios-Hoang, Keyes, and Johnson Director Vanessa Wyche.NASA Keyes’ hard work has been recognized with several awards throughout her career. She is proudest of earning the Office of Procurement Bubbee’s Coach Award, which is given to the team member most likely to serve as a mentor to colleagues. “Much of my professional and personal growth has stemmed from formal and informal mentors who supported me in navigating challenges, developing new skills, and creating environments for me to thrive,” she said. “I have a great appreciation for those mentors, and I strive to impact those around me similarly.” Keyes hopes to encourage the Artemis Generation to approach the future – and periods of uncertainty – with curiosity, resilience, and a responsibility to care for our planet and the universe. She looks forward to the continued expansion of access to space. “I hope to be around for the days where I can afford a reasonably priced, roundtrip ticket to the Moon,” she said. “Perhaps by then they will sell functional spacesuits in the local sporting goods stores.” View the full article

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Astronaut Jeanette Epps extracts DNA samples from bacteria colonies for genomic analysis aboard the International Space Station’s Harmony module.NASA In an effort to learn more about astronaut health and the effects of space on the human body, NASA is conducting a new experiment aboard the International Space Station to speed up the detection of antibiotic-resistant bacteria, thus improving the health safety not only of astronauts but patients back on Earth. Infections caused by antibiotic-resistant bacteria can be difficult or impossible to treat, making antibiotic resistance a leading cause of death worldwide and a global health concern. Future astronauts visiting the Moon or Mars will need to rely on a pre-determined supply of antibiotics in case of illness. Ensuring those antibiotics remain effective is an important safety measure for future missions. The Genomic Enumeration of Antibiotic Resistance in Space (GEARS) experiment, which is managed by NASA’s Ames Research Center in California’s Silicon Valley, involves astronauts swabbing interior surfaces across the space station and testing those samples for evidence of antibiotic-resistant bacteria, and in particular Enterococcus faecalis, a type of bacteria commonly found in the human body. The experiment is the first step in a series of work that seeks to better understand how organisms grow in a space environment, and how those similarities and differences might help improve research back on Earth. “Enterococcus is a type of organism that’s been with us since our ancestors crawled out of the ocean, and is a core member of the human gut,” said Christopher Carr, assistant professor at the Georgia Institute of Technology and co-principal investigator of GEARS. “It’s able to survive inside and outside of its host, which has allowed it to become the second highest leading cause of hospital-acquired infections. We want to understand how this type of organism is adapting to the space environment.” The GEARS experiment seeks to improve the detection and identification of these bacteria, building on existing efforts to understand what organisms grow on the station’s surfaces. “We’ve been monitoring the surfaces of the space station since 2000, but this experiment will give us insight beyond the identities of present organisms, which is currently all that is used for risk assessment,” said Sarah Wallace, a microbiologist at NASA’s Johnson Space Center in Houston and co-principal investigator of GEARS. “With the station orbiting close to Earth, it’s a low-risk space to evaluate and learn more about the frequency of this bacteria and how it responds to the space environment so we can apply this understanding to missions to the Moon and Mars, where resupplies are more complex.” Over the next year, astronauts will swab parts of the station and analyze samples by adding an antibiotic to the medium in which the samples will grow. The results will reveal where this and other resistant bacteria are growing and whether they can persist or spread across the station. I hope we can shine a light on rapidly analyzing bacteria: if we can do this in space, we can do it on Earth, too. Sarah WAllace NASA Microbiologist The experiment was originally launched to the ISS on the 30th SpaceX commercial resupply services (CRS) mission in March 2024, and the first round of GEARS testing turned up surprising results: very few resistant bacteria colonies, none of which were E. faecalis. This bodes well for the threat of antibiotic resistance in space. “There was some cleaning done before swabbing the station, which may have removed some bacteria,” said Carr. To better understand how and where risky bacteria may live, the astronauts paused some cleaning before the second round of swabbing. “We want the astronauts to have a clean environment, but we also want to test those high-touch areas, so they intentionally and briefly avoided cleaning some areas so we can understand how bacteria may grow or spread on the station.” This experiment is the first study to perform metagenomic sequencing in space, a method that analyzes all the genetic material in a sample to identify and characterize all organisms that are present, an important research and medical diagnostic capability for future deep space missions. The GEARS team hopes to create a rapid workflow to analyze bacteria samples, reducing the time between swabbing and test results from days to hours. That workflow could be applied in hospitals and make a huge impact when treating hospital-acquired infections from antibiotic-resistant microbes. The result could save lives – more than 35,000 people die each year as a result of antibiotic-resistant infections. The issue is personal to Wallace, who lost a family member to a hospital-acquired infection. “It’s not that uncommon: so many people have experienced this kind of loss,” said Wallace. “A method to give an answer in a matter of hours is huge and profound. It’s my job to keep the crew healthy, but we’re also passionate about bringing that work back down to Earth. I hope we can shine a light on rapidly analyzing bacteria: if we can do this in space, we can do it on Earth, too.” Genomic Enumeration of Antibiotic Resistance in Space (GEARS) was funded by the Biological and Physical Sciences Space Biology Program, with pioneering funding and support from the Mars Campaign office.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) During the Apollo program, when NASA sent humans to the Moon, those missions took several days to reach the Moon. The fastest of these was Apollo 8, which took just under three days to go from Earth orbit to orbit around the Moon. Now it’s possible to save some fuel by flying different kinds of trajectories to the Moon that are shaped in such a way to save fuel. And those trajectories can take more time, potentially weeks or months, to reach the Moon, depending on how you do it. Mars is further away, about 50 percent further away from the Sun than Earth is. And reaching Mars generally takes somewhere between seven to ten months, flying a relatively direct route. NASA’s Mars Reconnaissance Orbiter mission took about seven and a half months to reach Mars. And NASA’s MAVEN mission took about ten months to reach Mars. Jupiter is about five times further away from the Sun than the Earth is. And so in order to make those missions practical, we have to find ways to reduce the fuel requirements. And the way we do that is by having the spacecraft do some flybys of Earth and or Venus to help shape the spacecraft’s trajectory and change the spacecraft’s speed without using fuel. And using that sort of approach, it takes between about five to six years to reach Jupiter. So NASA’s Galileo mission, the first mission to Jupiter, took just a little over six years. And then NASA’s second mission to Jupiter, which was called Juno, took just under five years. So to get to the Moon takes several days. To get to Mars takes seven to ten months. And getting to Jupiter takes between five and six years.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA / Getty Images NASA has selected two new university student teams to participate in real-world aviation research challenges meant to transform the skies above our communities. The research awards were made through NASA’s University Student Research Challenge (USRC), which provides students with opportunities to contribute to NASA’s flight research goals. This round is notable for including USRC’s first-ever award to a community college: Cerritos Community College. We’re trying to tap into the community college talent pool to bring new students to the table for aeronautics. steven holz NASA Project Manager “We’re trying to tap into the community college talent pool to bring new students to the table for aeronautics,” said Steven Holz, who manages the USRC award process. “Innovation comes from everywhere, and people with different viewpoints, educational backgrounds, and experiences like those in our community colleges are also interested in aeronautics and looking to make a difference.” Real World Research Awards Through USRC, students interact with real-world aspects of the research ecosystem both in and out of the laboratory. They will manage their own research projects, utilize state-of-the-art technology, and work alongside accomplished aeronautical researchers. Students are expected to make unique contributions to NASA’s research priorities. USRC provides more than just experience in technical research. Each team of students selected receives a USRC grant from NASA – and is tasked with the additional challenge of raising funds from the public through student-led crowdfunding. The process helps students develop skills in entrepreneurship and public communication. The new university teams and research topics are: Cerritos Community College “Project F.I.R.E. (Fire Intervention Retardant Expeller)” will explore how to mitigate wildfires by using environmentally friendly fire-retardant pellets dropped from drones. Cerritos Community College’s team includes lead Angel Ortega Barrera as well as Larisa Mayoral, Paola Mayoral Jimenez, Jenny Rodriguez, Logan Stahl, and Juan Villa, with faculty mentor Janet McLarty-Schroeder. This team also successfully participated with the same research topic in in NASA’s Gateway to Blue Skies competition, which aims to expand engagement between the NASA’s University Innovation project and universities, industry, and government partners. Colorado School of Mines The project “Design and Prototyping of a 9-phase Dual-Rotor Motor for Supersonic Electric Turbofan” will work on a scaled-down prototype for an electric turbofan for supersonic aircraft. The Colorado School of Mines team includes lead Mahzad Gholamian as well as Garret Reader, Mykola Mazur, and Mirali Seyedrezaei, with faculty mentor Omid Beik.

This opportunity to partner with NASA, provide solar viewing glasses, and share eclipse knowledge with underserved communities off the central paths involved: Partnering with an undergraduate/amateur astronomer Taking a 3-week cooperative course (~12 hours coursework) Engaging their communities with eclipse resources by reaching 200+ people These Eclipse Ambassador partnerships allowed participants to grow together as they learned new tools and techniques for explaining eclipses and engaging with the public, and Eclipse Ambassadors are recognized for their commitment to public engagement. In January 2025, the Eclipse Ambassadors Off the Path project held a week-long Heliophysics Winter Field School (WFS), a culminating Heliophysics Big Year experience for nine undergraduate and graduate Eclipse Ambassadors. The WFS exposed participants to career opportunities and field experience in heliophysics, citizen science, and space physics. The program included expert lectures on space physics, aurora, citizen science, and instrumentation, as well as hands-on learning opportunities with Poker Flat Rocket Range, the Museum of the North, aurora chases, and more. Students not only learned about heliophysics, they also actively participated in citizen science data collection using a variety of instruments, as well as the Aurorasaurus citizen science project app. Interactive panels on career paths helped prepare them to pursue relevant careers. One participant, Sophia, said, “This experience has only deepened my passion for heliophysics, science communication, and community engagement.” Another participant, Feras, reflected, “Nine brilliant students from across the country joined a week-long program at the University of Alaska Fairbanks’ (UAF) Geophysical Institute, where we attended multiple panels on solar and space physics, spoke to Athabaskan elders on their connection to the auroras, and visited the Poker Flat Research Range to observe the stunning northern lights.” This undertaking would not have been possible without the coordination, planning, leadership of many. Principal Investigators included Vivian White (Eclipse Ambassadors, Astronomical Society of the Pacific, ASP) and Dr. Elizabeth McDonald (Aurorasaurus, NASA GSFC). Other partners included Lynda McGilvary (Geophysical Institute at UAF), Jen Arseneau (UAF), Shanil Virani (ASP), Andréa Hughes (NASA), and Lindsay Glesener (University of Minnesota), as well as knowledge holders, students, and scientists. The Eclipse Ambassadors Off the Path project is supported by NASA under cooperative agreement award number 80NSS22M0007 and is part of NASA’s Science Activation Portfolio.

This updated version of “the Pale Blue Dot,” made for the photo’s 30th anniversary in 2020, uses modern image-processing software and techniques to revisit the well-known Voyager view while attempting to respect the original data and intent of those who planned the images.NASA/JPL-Caltech Earth is but a tiny light blue dot in this 30th anniversary version of the iconic “Pale Blue Dot” image. The original photo, taken by NASA’s Voyager 1 spacecraft on Feb. 14, 1990, is now 35 years old. Voyager 1 was 3.7 billion miles (6 billion km) away from the Sun, giving it a unique vantage point to take a series of photos that created a “family portrait” of our solar system. Voyager’s view was important to Carl Sagan and the Voyager Imaging Team; they felt this photo was needed to show Earth’s vulnerability and that our home world is just a tiny, fragile speck in the cosmic ocean.

Rodent Research-28 fluorescein angiogram of the microvascular circulation of the mouse retina.Image courtesy: Oculogenex Inc. Key Takeaways A total of 361 publications were collected in FY-24. These publications include peer-reviewed scientific studies or other literature such as books and patents published recently or years prior. More than 80% of the publications collected in FY-24 were from research sponsored by NASA and JAXA. In FY-24, the predominant area of study for publications was Earth and Space science. The results obtained were primarily generated via Derived Results, studies that retrieve open data from online sources to make new discoveries. These Derived publications indicate a 39% return on investment. A total of 4,438 publications have been gathered since the beginning of station, and about 16% of this literature has been published in top-tier journals. The year-over-year growth of top-tier publications has been greater than the growth of regular publications. In 13 years, there was a 22% growth of top-tier publications and a 0.47% growth of regular publications. Almost 80% of top-tier results have been published in the past seven years. Station research continues to surpass national and global standards of citation impact. This year, a simplified hierarchy map showing the nested categories of station disciplines, subdisciplines, and selected keywords is presented to represent the more than 15,000 topic key words generated by the studies. Station research has seen a remarkable growth of international collaboration since its first days of assembly in 1999. Currently, about 40% of the research produced by station is the result of a collaboration between two or more countries. To date, the United States has participated in 23% of international collaborations. Of the nearly 4,000 investigations operated on station since Expedition 0, approximately 59% are identified as completed. From this subset of completed investigations, studies directly conducted on station rather than Derived Results have produced the most scientific results. This pattern differs from analyses conducted with all publication data. Introduction The International Space Station is a state-of-the art laboratory in low Earth orbit. Since the year 2000, distinguished researchers from a myriad of disciplines around the world have been sending equipment and investigations to station to learn how space-related variables affect the human body, plant and microbial life, physical processes, equipment function, and more. Sophisticated remote sensing techniques and telescopes attached to station also observe the Earth and the universe to enhance our understanding of weather patterns, biomass changes, and cosmic events. Investigations can be operated remotely from Earth with ground control support, directly on station with the help of crew members, or autonomously (without human assistance). The most recent science conducted on station has engaged private astronauts to advance the research endeavors of the commercial sector. The improvement of these science operations (i.e., how data is collected and returned) has led to more reliable scientific results. Additionally, extensive domestic and international collaboration bridging academic institutions, corporations, and funding agencies has produced high quality and impactful research that inspires new generations of students, researchers, and organizations looking to solve problems or innovate in emerging fields. The studies highlighted in this report are only a small, representative sample of the research conducted on station in the past 12 months. Many more groundbreaking findings were reported in fiscal year 2024 (FY- 24), including: Plant adaptation through the adjustment of regulatory proteins, which can lead to sustainable food production on the Moon and Mars (BRIC-LED-001). A connection between downregulated mitochondrial gene pathways and neurotransmitter signaling dysfunction that could assist the development of new pharmaceutical or nutritional therapies to prevent strength loss in neuromuscular disorders. (Microbial Observatory-1). The precise measurement of hydrogen isotopes to provide a better assessment of dark matter (AMS-02). The adaptation of a permanent flow cytometer in space that enables the examination of blood counts, hormones, enzymes, nucleic acids, proteins, and biomarkers to assess crew health in real time (rHEALTH). The behavior of oil-in-water drops in microgravity (i.e., oil drops grow over time, but drop displacement decreases). Understanding the behavior of oils, dyes, and detergents can lead to a safer environment and sustainability of emulsion technologies in the food, pharmaceutical, paint, and lubrication industries (FSL Soft Matter Dynamics-PASTA). Fundamental and applied research conducted on station improves the state of scientific understanding. Whether it is through the examination of microgravity and radiation effects, or through the testing of countermeasures, new materials, and computing algorithms; the hard work of integrating flight operations with scientific objectives is carried out to protect our planet, improve our health, and learn more about our place in the universe. The following pages aim to demonstrate how station is revolutionizing science through cooperation, curiosity, and ingenuity. Projects that may have begun as simple ideas are now shaping the way we think about and operate in space to advance our goal of going to the Moon and beyond. NASA astronaut and Expedition 70 Flight Engineer Jasmin Moghbeli poses in front of the Kibo laboratory module’s Advanced Plant Habitat housing tomato plants for an experiment investigating how the plant immune system adapts to spaceflight and how spaceflight affects plant production. NASA ID: iss070e073612.Credits: NASA Bibliometric Analyses: Measuring Space Station Impacts Literature associated with space station research results (e.g., scientific journal articles, books, patents) is collected, curated, and linked to investigations. The content from these publications is classified based on how the results are obtained. The current classifications are: Flight Preparation Results – publications about the development work performed for an investigation or facility prior to operation on space station. Station Results – publications that provide information about the performance and results of an investigation or facility as a direct implementation on station or on a vehicle to space station. Derived Results – publications that use open data from an investigation that operated on station. Access to raw data for new researchers expands global knowledge and scientific benefits. Related – publications that indirectly lead to the development of an investigation or facility. To date, over 2,200 publications have been identified as Related. This count of Related publications is not included in the analyses presented in this report. Projects taking place on station (facilities or investigations) are assigned to one of six science disciplines: Biology and Biotechnology: Includes plant, animal, cellular biology, habitats, macromolecular crystal growth, and microbiology. Earth and Space Science: Includes astrophysics, remote sensing, near-Earth space environment, astrobiology, and heliophysics. Educational and Cultural Activities: Includes student-developed investigations and competitions. Human Research: Includes crew healthcare systems, all human-body systems, nutrition, sleep, and exercise. Physical Science: Includes combustion, materials, fluid, and fundamental physics. Technology Development and Demonstration: Includes air, water, surface, and radiation monitoring, robotics, small satellites and control technologies, and spacecraft materials. Facilities consist of the infrastructure and equipment on station that enable the research to be conducted (e.g., workstation “racks” containing power, data and thermal control, furnaces, crystallization units, animal and plant habitats). Investigations are research projects with one or multiple science objectives. Investigations may use a facility to execute the experiments. A publicly accessible database of space station investigations, facilities, and publications can be found in the Space Station Research Explorer (SSRE) website. Through bibliometric analyses, the examination of publications and citations in different categories, we learn about research productivity, quality, collaboration, and impact. These measurements allow our organization to identify trends in research growth to better plan and support new scientific endeavors. The analyses included in this report serve to answer questions related to fiscal year data and total publication data to promote research accountability and integrity and ensure benefits to humanity. Station research produced in FY-2024 Between Oct. 1, 2023, and Sept. 30, 2024, we identified a total of 361 publications associated with station research. Of these 361 publications, 52 were published in Biology and Biotechnology, 176 in Earth and Space, 5 in Educational and Cultural Activities, 40 in Human Research, 56 in Physical Science, and 32 in Technology Development and Demonstration. This publication count broken out by research discipline and space agency is shown in Figure 1A. Of the 361 publications, 41 were classified as Flight Preparation Results, 178 as Station Results, and 140 as Derived Results. Because Derived Results are new scientific studies generated from shared data, derived science is an additional return on the investment entrusted to station. In FY-24, this return on investment was 39%; a 12% increase from FY-23. Figure 1B shows this publication data broken out by research discipline and publication type. Figure 1A. A total of 361 publications were collected in FY-24. Over 80% of the publications reported results in Earth and Space, primarily from investigations associated with NASA and JAXA research. Figure 1B, A total of 361 publications were collected in FY-24. Most publications in Earth and Space came from Derived Results associated with NASA and JAXA research. These Derived Results demonstrate a return on investment of 39%, a 12% increase from FY-23. Overall growth, quality, impact, and diversity of station research Growth: A total of 4,438 publications have been collected since station began operations with 176 publications (4%) from work related to facilities on station. In Figure 2A, we show the growth of both regular and top-tier science over the years. Top-tier publications are studies published in scientific journals ranked in the top 100 according to ClarivateTM (Web of ScienceTM)1, a global database that compiles readership and citation standards to calculate a journal’s Eigenfactor Score2 and ranking. Regular publications include literature published in sources that may be specific to microgravity research but are not ranked. Our data shows that over a 13-year period from 2011 to 2023, regular publications grew 0.47% per year and top-tier publications grew 22% per year. Some of the subdisciplines that have experienced most growth from station research are astrophysics (707 publications), Earth remote sensing (266 publications), fluid physics (245 publications), and microbiology (214 publications). Quality: About 16% of station results have been published in top-tier journals. However, in Figure 2B we zoom in to examine the growth of top-tier publications given their station science discipline, showing that almost 80% of top-tier research has been published in the past seven years. Currently, a total of 696 articles have been published in top-tier journals and about 53% of this total are Derived Results from Earth and Space science investigations. Figure 2A. Growth of regular and top-tier research publications over time. About 16% of station results have been published in top-tier journals. Inset shows the growth of microgravity- and non-microgravity-specific sources used in regular publications. Figure 2B. Growth of top-tier research publications by station research discipline (n = 696). There has been a significant increase of top-tier articles published since 2018, with a little over 50% emerging from Derived Results in Earth and Space science. Table inset shows the top-tier journals with most station research published. Impact: Previous analyses have demonstrated that the citation impact of station research has superseded national and global standards since 2011 (See Annual Highlights of Results FY-2023). This pattern continues today. Diversity: Station science covers six major science disciplines, 73 subdisciplines, and thousands of topic keywords within each subdiscipline. A precise visualization of such abundant diversity would be overwhelming and impenetrable. However, plotting a few topic keywords within each sub-discipline succinctly shows the breadth of science station has to offer (Figure 3). For a better appreciation of station’s diversity, see the interactive hierarchy diagram online. Note that some topics, such as radiation, are studied from multiple perspectives (e.g., radiation measurement through physical science, radiation effects through human research, and shielding through technology development). Topic keywords were obtained using ClarivateTM (Web of ScienceTM).1 Station research collaboration Previous analyses have shown the growth of collaboration between countries throughout the years based on co-authorship (See Annual Highlights of Results FY-2023). In a new analysis conducted with country data obtained through Dimensions.ai3 (n = 3,309 publications), we calculated that about 40% of the publications produced from station research are collaborations between several countries, and about 60% are intercollegiate collaborations within individual countries. As seen in the space agency networks in Figure 4, the United States participates in approximately 23% of the collaborations with other countries, making it the most collaborative country. Figure 4: Country collaboration in station research based on publication co-authorship. Networks include up to five countries collaborating in an investigation. Nodes and links from countries that published their research independently are not included. From research ideas to research findings Nearly 4,000 investigations have operated since Expedition 0; with a subset of 2,352 investigations (approximately 59%) marked as complete. These completed investigations have concluded their science objectives and reported findings. In Figure 5, we show the citation output from publications exclusively tied to completed investigations. In this Sankey diagram, Times Cited corresponds to the count of publications with at least one citation in each publication type (Station Results, Flight Preparation Results, and Derived Results). This citation count adequately parallels the total number of citations per publication and allows the visualization of a comprehensible chart. This analysis demonstrates that most completed investigations have reported results directly from studies conducted on station, followed by studies conducted in preparation to go to space, and finally by studies derived from open science available online. Likewise, results obtained straight from station receive more citations (e.g, over 46,000) than Flight Preparation (3,636 citations) or Derived results (936 citations). This pattern differs from analyses including all publication data in Figures 1 and 2. Linking Space Station Benefits Space station research results lead to benefits for human exploration of space, benefits to humanity, and the advancement of scientific discovery. This year’s Annual Highlights of Results from the International Space Station includes descriptions of just a few of the results that were published from across the space station partnership during the past year. EXPLORATION: Space station investigation results have yielded updated insights into how to live and work more effectively in space by addressing such topics as understanding radiation effects on crew health, combating bone and muscle loss, improving designs of systems that handle fluids in microgravity, and determining how to maintain environmental control efficiently. DISCOVERY: Results from the space station provide new contributions to the body of scientific knowledge in the physical sciences, life sciences, and Earth and space sciences to advance scientific discoveries in multi-disciplinary ways. BENEFITS FOR HUMANITY: Space station science results have Earth-based applications, including understanding our climate, contributing to the treatment of disease, improving existing materials, and inspiring the future generation of scientists, clinicians, technologists, engineers, mathematicians, artists, and explorers.

5 min read Ultra-low-noise Infrared Detectors for Exoplanet Imaging A linear-mode avalanche photodiode array in the test dewar. The detector is the dark square in the center. Michael Bottom, University of Hawai’i One of the ultimate goals in astrophysics is the discovery of Earth-like planets that are capable of hosting life. While thousands of planets have been discovered around other stars, the vast majority of these detections have been made via indirect methods, that is, by detecting the effect of the planet on the star’s light, rather than detecting the planet’s light directly. For example, when a planet passes in front of its host star, the brightness of the star decreases slightly. However, indirect methods do not allow for characterization of the planet itself, including its temperature, pressure, gravity, and atmospheric composition. Planetary atmospheres may include “biosignature” gases like oxygen, water vapor, carbon dioxide, etc., which are known to be key ingredients needed to support life as we know it. As such, direct imaging of a planet and characterization of its atmosphere are key to understanding its potential habitability. But the technical challenges involved in imaging Earth-like extrasolar planets are extreme. First such planets are detected only by observing light they reflect from their parent star, and so they typically appear fainter than the stars they orbit by factors of about 10 billion. Furthermore, at the cosmic distances involved, the planets appear right next to the stars. A popular expression is that exoplanet imaging is like trying to detect a firefly three feet from a searchlight from a distance of 300 miles. Tremendous effort has gone into developing starlight suppression technologies to block the bright glare of the star, but detecting the light of the planet is challenging in its own right, as planets are incredibly faint. One way to quantify the faintness of planetary light is to understand the photon flux rate. A photon is an indivisible particle of light, that is, the minimum detectable amount of light. On a sunny day, approximately 10 thousand trillion photons enter your eye every second. The rate of photons entering your eye from an Earth-like exoplanet around a nearby star would be around 10 to 100 per year. Telescopes with large mirrors can help collect as much of this light as possible, but ultra-sensitive detectors are also needed, particularly for infrared light, where the biosignature gases have their strongest effects. Unfortunately, state-of-the-art infrared detectors are far too noisy to detect the low level of light emitted from exoplanets. With support from NASA’s Astrophysics Division and industrial partners, researchers at the University of Hawai’i are developing a promising detector technology to meet these stringent sensitivity requirements. These detectors, known as avalanche photodiode arrays, are constructed out of the same semiconductor material as conventional infrared sensors. However, these new sensors employ an extra “avalanche” layer that takes the signal from a single photon and multiplies it, much like an avalanche can start with a single snowball and quickly grow it to the size of a boulder. This signal amplification occurs before any noise from the detector is introduced, so the effective noise is proportionally reduced. However, at high avalanche levels, photodiodes start to behave badly, with noise exponentially increasing, which negates any benefits of the signal amplification. Late University of Hawai’i faculty member Donald Hall, who was a key figure in driving technology for infrared astronomy, realized the potential use of avalanche photodiodes for ultra-low-noise infrared astronomy with some modifications to the material properties. University of Hawai’i team members with cryogenic dewar used to test the sensors. From left to right, Angelu Ramos, Michael Bottom, Shane Jacobson, Charles-Antoine Claveau. Michael Bottom, University of Hawai’i The most recent sensors benefit from a new design including a graded semiconductor bandgap that allows for excellent noise performance at moderate amplification, a mesa pixel geometry to reduce electronic crosstalk, and a read-out integrated circuit to allow for short readout times. “It was actually challenging figuring out just how sensitive these detectors are,” said Michael Bottom, associate professor at the University of Hawai’i and lead of development effort. “Our ‘light-tight’ test chamber, which was designed to evaluate the infrared sensors on the James Webb Space Telescope, was supposed to be completely dark. But when we put these avalanche photodiodes in the chamber, we started seeing light leaks at the level of a photon an hour, which you would never be able to detect using the previous generation of sensors.” The new designs have a format of one megapixel, more than ten times larger than the previous iteration of sensors, and circuitry that allows for tracking and subtracting any electronic drifts. Additionally, the pixel size and control electronics are such that these new sensors could be drop-in replacements for the most common infrared sensors used on the ground, which would give new capabilities to existing instruments. Image of the Palomar-2 globular cluster located in the constellation of Auriga, taken with the linear-mode avalanche photodiode arrays, taken from the first on-sky testing of the sensors using the University of Hawai’i’s 2.2 meter telescope. Michael Bottom, University of Hawai’i Last year, the team took the first on-sky images from the detectors, using the University of Hawai’i’s 2.2-meter telescope. “It was impressive to see the avalanche process on sky. When we turned up the gain, we could see more stars appear,” said Guillaume Huber, a graduate student working on the project. “The on-sky demonstration was important to prove the detectors could perform well in an operational environment,” added Michael Bottom. According to the research team, while the current sensors are a major step forward, the megapixel format is still too small for many science applications, particularly those involving spectroscopy. Further tasks include improving detector uniformity and decreasing persistence. The next generation of sensors will be four times larger, meeting the size requirements for the Habitable Worlds Observatory, NASA’s next envisioned flagship mission, with the goals of imaging and characterizing Earth-like exoplanets.

Modeling properties of thunderstorm discharges Researchers report detailed physical properties of different types of corona discharges, including single- and multi-pulse blue discharges linked to powerful but short-lived electrical bursts near the tops of clouds. These details provide a reference for further investigation into the physical mechanisms behind these discharges and their role in the initiation of lightning, an important problem in lightning physics. An ESA (European Space Agency) instrument used to study thunderstorms, Atmosphere-Space Interactions Monitor (ASIM) provides insights into their role in Earth’s atmosphere and climate, including mechanisms behind the creation of lightning. Understanding how thunderstorms and lightning disturb the upper atmosphere could improve atmospheric models along with climate and weather predictions. These high-altitude discharges also affect aircraft and spacecraft safety. An artist’s impression of a blue jet as observed from the International Space Station.Mount Visual/University of Bergen/DTU Space Evaluating effects of climate change on oceans Researchers conclude that the space station’s ECOSTRESS instrument yields highly accurate sea surface temperature data. Given the instrument’s global coverage and high spatial resolution, these data have potential use in studies of biological and physical oceanography to evaluate regional and local effects of climate change. ECOSTRESS resolves oceanographic features not detectable in imagery from NOAA’s Visible Infrared Imaging Radiometer Suite satellite, and has open-ocean coverage, unlike Landsat. Satellites are a fundamental tool to measure sea surface temperatures, which are rising across all oceans due to atmospheric warming induced by climate change. The ECOSTRESS instrument, the white box in the center, is visible on the outside of the station.NASA Describing a gamma ray burst Researchers report detailed observations and analysis of emissions from an exceptionally bright gamma ray burst (GRB), 210619B, detected by the station’s ASIM and other satellite and ground-based instruments. These observations could be useful in determining various properties of GRBs and how they change during different phases. Believed to be generated by the collapse of massive stars, GRBs are the brightest, most explosive transient electromagnetic events in the universe. ASIM can observe thunderstorm discharges difficult to observe from the ground. It has a mode where a detected event triggers observation and onboard storage of data.

4 Min Read What is an Engineer? (Grades K-4) This article is for students grades K-4. Engineers solve problems. They use science and math to create new things or make things work better. There are different kinds of engineers. They work on different kinds of projects. Some engineers design buildings or machines. Others find ways to move heat, power, or water from one place to another. Some create new tools. NASA needs engineers. They design the things humans need to fly in space or on airplanes. Engineers make great ideas become real. What do NASA engineers work on? NASA has many missions. These missions need different kinds of engineers. Here are some of the ways engineers help NASA get the job done. Spacecraft: These are vehicles that fly in space. NASA engineers decide how a spacecraft should be built and what it should do. They also make sure it will keep astronauts safe. Airplanes: NASA engineers work on airplanes. They design how the plane will look, how fast it will fly, and how much fuel it will use. Telescopes: Telescopes help us see space objects like stars and planets. Some telescopes are placed in orbit for the best view. NASA engineers design them to work in space. Computers: Computers can do complex tasks faster than people. NASA engineers write code that tells computers what to do. Anthony Vareha, NASA flight director Why is it fun to be a NASA engineer? At NASA, engineers get to work on cool projects. They use science and creativity to find new ways to reach big goals. Here are some of the reasons they like their work. “Being an engineer is like solving a huge puzzle or building something cool with building blocks. The difference is that the things we make help make the world better and improve people’s lives.” – Othmane Benefan, materials research engineer “I like being an engineer because I get to learn new things almost every day. Most of the engineering projects at NASA are super unique because we are building satellites that study new places all over the solar system (planets, asteroids, even the Sun), and it’s really fun to learn all the ways that we can use robots to explore.” – Phillip Hargrove, launch mission integration engineer “I love to build and create things. At NASA, there’s always something to do, and I get to work with people I enjoy.” – Jenna Sayler, aerospace engineer “I love being an engineer because I love trying to understand how things work. There’s a lot of stuff in our universe. Engineering is the tool I’ve chosen to help make sense of it all.” – Brian Kusnick, mechanical engineer Elaine Stewart, contamination control engineer What are some things I can do to help me become an engineer? Be curious and excited to learn new things. Learn more about how different types of machines work. Practice making, building, or tinkering with things. Work hard in math and science classes. When you get to middle school or high school, try a NASA student challenge or apply to be a NASA intern. Students over age 16 can apply for NASA internships. Interns work on real projects. NASA team members help guide interns as they learn. Wendy Okolo, Ph.D., aerospace research engineer How can I try engineering today? NASA has fun engineering activities that you can do at home.
