Many of us wear devices that count our steps, measure our heart rate, track sleep patterns, and more. This information can help us make healthy decisions – research shows the devices encourage people to move more, for example – and could flag possible problems, such as an irregular heartbeat.
Wearable monitors also have become common tools for research on human health, including studies on the International Space Station. Astronauts have worn special watches, headbands, vests, and other devices to help scientists examine sleep quality, effectiveness of exercise, heart health, and more.
Warm to the core
Spaceflight can affect body temperature regulation and daily rhythms due to factors such as the absence of convection (a natural process that transfers heat away from the body) and changes in the cardiovascular and metabolic systems.
A current investigation from ESA (European Space Agency), Thermo-Mini or T-Mini examines how the body regulates its core temperature during spaceflight. The study uses a non-invasive headband monitor that astronauts can wear for hours at a time. Data from the monitor allow researchers to determine the effect on body temperature from environmental and physiological factors such as room temperature and humidity, time of day, and physical stress. The same type of sensor already is used on Earth for research in clinical environments, such as improving incubators, and studies of how hotter environments affect human health.
Thermolab, an earlier ESA investigation, examined thermoregulatory and cardiovascular adaptations during rest and exercise in microgravity. Researchers found that core body temperature rises higher and faster during exercise in space than on Earth and that the increase was sustained during rest, a phenomenon that could affect the health of crew members on long-term spaceflight. The finding also raises questions about the thermoregulatory set point humans are assumed to have as well as our ability to adapt to climate change on Earth.

Spaceflight is known to disrupt sleep-wake patterns. Actiwatch Spectrum, a device worn on the wrist, contains an accelerometer to measure motion and photodetectors to monitor ambient lighting. It is an upgrade of previous technology used on the space station to monitor the length and quality of crew member sleep. Data from earlier missions show that crew members slept significantly less during spaceflight than before and after. The Actiwatch Sleep-Long investigation used an earlier version of the device to examine how ambient light affects the sleep-wake cycle and found an association between sleep deficiency and changes during spaceflight in circadian patterns, or the body’s response to a normal 24-hour light and dark cycle. Follow up studies are testing lighting systems to address these effects and help astronauts maintain healthy circadian rhythms.
NASA astronaut Sunita Williams wears an Actiwatch as she conducts research.NASA Wearable Monitoring tested a lightweight vest with embedded sensors to monitor heart rate and breathing patterns during sleep and help determine whether changes in heart activity affect sleep quality. The technology offers a significant advantage by monitoring heart activity without waking the test subject and could help patients on Earth with sleep disorders. Researchers reported positive performance and good quality of recorded signals, suggesting that the vest can contribute to comprehensive monitoring of individual health on future spaceflight and in some settings on Earth as well.
These and other studies support development of countermeasures to improve sleep for crew members, helping to maintain alertness and lessen fatigue during missions.
(Not) waiting to exhale
Humans exhale carbon dioxide and too much of it can build up in closed environments, causing headaches, dizziness, and other symptoms. Spacecraft have systems to remove this substance from cabin air, but pockets of carbon dioxide can form and be difficult to detect and remove. Personal CO2 Monitor tested specially designed sensors attached to clothing to monitor the wearer’s immediate surroundings. Researchers reported that the devices functioned adequately as either crew-worn or static monitors, an important step toward using them to determine how carbon dioxide behaves in enclosed systems like spacecraft.
One of the wearable carbon dioxide monitors clipped to the wall near a crew sleeping compartment. Radiation in real time
EVARM, an investigation from CSA (Canadian Space Agency), used small wireless dosimeters carried in a pocket to measure radiation exposure during spacewalks. The data showed that this method is a feasible way to measure radiation exposure, which could help focus routine dosage monitoring where it is most needed. Any shielding and countermeasures developed also could help protect people who work in high-radiation areas on Earth.
ESA’s Active Dosimeter tested a radiation dosimeter worn by crew members to measure changes in their exposure over time based on the space station’s orbit and altitude, the solar cycle, and solar flares. Measurements from the device allowed researchers to analyze radiation dosage across an entire space mission.
ESA astronaut Thomas Pesquet holds one of the mobile units for the Active Dosimeter study.NASA The Active Dosimeter also was among the instruments used to measure radiation on NASA’s Orion spacecraft during its 25.5-day uncrewed Artemis I mission around the Moon and back in 2022.
Another device tested on the space station and then on Artemis I, AstroRad Vest is designed to protect astronauts from solar particle events. Researchers used these and other radiation measuring devices to show that Orion’s design can protect its crew from potentially hazardous radiation levels during lunar missions.
The International Space Station serves as an important testbed for these technologies and many others being developed for future missions to the Moon and beyond.

NASA/Loral O’Hara The Choctaw Heirloom Seeds investigation flew five varieties of heirloom seeds from the Choctaw Nation of Oklahoma aboard the International Space Station in early November 2023. The seeds are Isito (Choctaw Sweet Potato Squash), Tobi (Smith Peas), Tanchi Tohbi (Flour Corn), Tvnishi (Lambsquarter), and Chukfi Peas. The seeds spent six months aboard station, returning to Earth in April 2024.
Next spring, Jones Academy students will plant the space-flown seeds alongside Earth-bound seeds of the same type in the school’s Growing Hope Garden. Students will hypothesize how the seeds will grow and make observations throughout the growing season.
Middle school teachers are developing curriculum incorporating the seeds’ journey to space station and students’ experiments in the garden. This research could impact Native and Indigenous populations across the United States, inviting underrepresented groups to engage with science, technology, engineering, and mathematics.

Summary of the Second OMI–TROPOMI Science Team Meeting
Introduction
The second joint Ozone Monitoring Instrument (OMI)–TROPOspheric Monitoring Instrument (TROPOMI) Science Team (ST) meeting was held June 3–6, 2024. The meeting used a hybrid format, with the in-person meeting hosted at the National Center for Atmospheric Research (NCAR) in Boulder, CO. This was the first OMI meeting to offer virtual participation since the COVID-19 travel restrictions. Combining the onsite and virtual attendees, the meeting drew 125 participants – see Photo.
OMI flies on NASA’s Earth Observing System (EOS) Aura platform, launched July 15, 2004. TROPOMI flies on the European Space Agency’s (ESA)–Copernicus Sentinel-5 Precursor platform. OMI has collected nearly 20 years of data and TROPOMI now has amassed 5 years of data.
Meeting content was organized around the following four objectives:
discussion of the final reprocessing of OMI data (called Collection 4) and of data preservation; discussion of OMI data continuity and enhancements using TROPOMI measurements; development of unique TROPOMI products [e.g., methane (CH4)], applications (e.g., tracking emissions – and using them as indicators of socioeconomic and military activities), and new focus regions (e.g., Africa); and leverage synergies between atmospheric composition (AC) and greenhouse gas (GHG) missions, which form the international constellation of low Earth orbit (LEO) and geostationary orbit (GEO) satellites. The remainder of this article summarizes the highlights from each day of the meeting.

The topics covered on the first day of the meeting included OMI instrument performance, calibration, final Collection 4 reprocessing, and plans for data preservation.
OMI and Data Products Update
Pieternel Levelt [Royal Netherlands Meteorological Institute (KNMI)—OMI Principal Investigator (PI) and NCAR’s Atmospheric Chemistry Observations & Modeling (ACOM) Laboratory—Director] began her presentation by dedicating the meeting to the memory of Johan de Vries, whose untimely death came as a shock to the OMI and TROPOMI teams – see In Memoriam: Johan de Vries for a celebration of his accomplishments and contributions to the OMI-TROPOMI team. She then went on to give a status update on OMI, which is one of two currently operating instruments on EOS Aura [the other being the Microwave Limb Sounder (MLS)]. OMI is the longest operating and stable ultraviolet–visible (UV-VIS) spectrometer. It continues to “age gracefully” thanks to its design, contamination control measures undertaken after the launch, and stable optical bench temperature. Lessons learned during integration of OMI on the Aura spacecraft (e.g., provide additional charged couple device shielding) and operations (i.e., monitor partial Earth-view port blockages) guided the development and operations of the follow-on TROPOMI mission.
Continued monitoring of OMI performance is crucial for extending science- and trend-quality OMI records to the end of the Aura mission (currently expected in 2026). Antje Ludewig [KNMI] described the new OMI Level-1B (L1B) processor (Collection 4), which is based on TROPOMI data flow and optimized calibrations. The processor has been transferred to the U.S. OMI ST, led by Joanna Joiner [NASA’s Goddard Space Flight Center (GSFC)]. Matthew Bandel [Science Systems and Applications, Inc. (SSAI)] described NASA’s new OMI monitoring tools.
Sergey Marchenko [SSAI] discussed OMI daily spectral solar irradiance (SSI) data, which are used for monitoring solar activity and can be compared with the dedicated Total and Spectral Solar Irradiance Sensor (TSIS-1) on the International Space Station. Continuation of OMI measurements will allow comparisons with the upcoming NASA TSIS-2 mission. Antje Inness [European Centre for Medium-range Weather Forecasts (ECMWF)] described operational assimilation of OMI and TROPOMI near-real time data into the European Copernicus Atmosphere Monitoring Service (CAMS) daily analysis/forecast and re-analysis – see Figure 1.
In Memoriam: Johan de Vries
Johan de Vries
June 10, 1956 – May 8, 2024 Johan de Vries [Airbus Netherlands—Senior Specialist Remote Sensing] passed away suddenly on May 8, 2024, after a distinguished career. As a member of the Ozone Monitoring Instrument (OMI)–TROPOspheric Monitoring Instrument (TROPOMI) program, Johan conceptualized the idea of using a two-dimensional (2D) charged couple detector (CCD) for the OMI imaging spectrometer. This “push-broom” design led to high-spatial resolution spectra combined with high-spatial resolution and daily global coverage capability. His pioneering design for OMI has now been repeated on several other U.S. and international atmospheric composition measuring instruments – in both low and geostationary orbits – that are either in orbit or planned for launch soon. This achievement ensures that Johan’s legacy will live on for many years to come as these push-broom Earth observing spectrometers result in unprecedented data for environmental research and applications. The OMI and TROPOMI teams express their deepest condolences to de Vries family and colleagues over this loss.

The U.S. and Netherlands OMI STs continue to collaborate closely on reprocessing and improving OMI and TROPOMI L2 science products. During the meeting, one or more presenters reported on each product, which are described in the paragraphs that follow.
Serena Di Pede [KNMI] discussed the latest algorithm updates to the Collection 4 OMI Total Column Ozone (O3) product, which is derived using differential absorption spectroscopy (DOAS). She compared results from the new algorithm with the previous Collection 3 and with both the TROPOMI and OMI NASA O3 total column (Collection 3) algorithms. Collection 4 improved on previous versions by reducing the retrieval fit error and the along-track stripes of the product.
Juseon “Sunny” Bak and Xiong Liu [both from Smithsonian Astrophysical Observatory (SAO)] gave updates on the status of the Collection 4 O3 profile products.
Lok Lamsal [GSFC/University of Maryland, Baltimore County (UMBC)] and Henk Eskes [KNMI] compared Collection 3 and Collection 4 of the nitrogen dioxide (NO2) products.
Zolal Ayzpour [SAO] discussed the status of the OMI Collection 4 formaldehyde (HCHO) product.
Hyeong-Ahn Kwon [SAO] presented a poster that updated the Glyoxal product.
Omar Torres [GSFC] and Changwoo Ahn [GSFC/SSAI] presented regional trend analyses using the re-processed OMI Collection 4 absorbing aerosol product – see Figure 2.
Figure 2. Reprocessed OMI records (from Collection 4) of monthly average aerosol optical depth (AOD) at 388 nm derived from the OMI aerosol algorithm (OMAERUV) over Western North America (WNA): 30°N–50°N, 110°W–128°W) [top] and over Eastern China (EC): 25°N–43°N, 112°E–124°E) [bottom]. A repeatable annual cycle over WNA occurred with autumn minimum at around 0.1 and a spring maximum in the vicinity of 0.4 during the 2005–2016 period. After 2017 much larger AOD maxima in the late summer are associated with wildfire smoke occurrence. Over EC (bottom) the 2005–2014 AOD record depicts a large spring maxima (0.7 and larger) due to long-range transport of dust and secondary pollution aerosols followed by late autumn minima (around 0.3). A significant AOD decrease is observed starting in 2015 with reduced minimum and maximum values to about 0.2 and 0.5 respectively. The drastic change in AOD load over this region is associated with pollution control measures enacted over the last decade. Figure credit: Changwoo Ahn/GSFC/SSAI and Omar Torres/GSFC Updates on EOS Synergy Products
Several presenters and posters during the meeting gave updates on EOS synergy products, where OMI data are combined with data from another instrument on one of the EOS flagships. These are described below.
Brad Fisher [SSAI] presented a poster on the Joint OMI–Moderate Resolution Imaging Spectroradiometer (MODIS) cloud products.
Wenhan Qin [GSFC/SSAI] presented a poster on the MODIS–OMI Geometry Dependent Lambertian Equivalent Surface Reflectivity (GLER) product.
Jerry Ziemke [GSFC and Morgan State University (MSU)] presented on the OMI–MLS Tropospheric Ozone product that showed post-COVID tropospheric O3 levels measured using this product, which are consistent with similar measurements obtained using other satellite O3 data – see Figure 3.
Figure 3. Anomaly maps of merged tropospheric column O3 (TCO) satellite data (Dobson Units) for spring–summer 2020–2023. In this context, an anomaly is defined as deseasonalized O3 data. The anomaly maps are derived by first calculating seasonal climatology maps for 2016–2019 (i.e., pre-COVID pandemic) and then subtracting these climatology maps from the entire data record.
Note: The sensors used in this analysis include: the Ozone Mapping and Profiler Suite (OMPS)/ Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) and Cross-track Infrared Sounder (CrIS) on the Joint Polar Satellite System (JPSS) missions, which currently include the joint NASA–NOAA Suomi National Polar-orbiting Partnership (Suomi NPP), NOAA-20, and NOAA-21; the Earth Polychromatic Imaging Camera (EPIC)/MERRA-2 on the Deep Space Climate Observatory (DSCOVR); the Ozone Monitoring Instrument (OMI) and Microwave Limb Sounder (MLS), both on EOS Aura; the Infrared Atmospheric Sounding Interferometer (IASI)/ Fast Optimal Retrievals on Layers (FORLI), IASI/SOftware for Fast Retrievals of IASI Data (SOFRID), and IASI/Global Ozone Monitoring Experiment–2 (GOME2). IASI flies on the European MetOp-A, -B, and -C missions. The OMPS/MERRA-2 and EPIC/MERRA-2 products subtract coincident MERRA-2 stratospheric column O3 from total O3 to derive tropospheric column O3. Figure credit: Jerry Ziemke/GSFC and Morgan State University (MSU) Updates on Multisatellite Climate Data Records
The OMI ST also discussed refining and analyzing multisatellite climate data records (CDRs) that have been processed with consistent algorithms. Several presenters reported on this work, who are mentioned below.
Jenny Stavrakou [Koninklijk Belgisch Instituut voor Ruimte-Aeronomie, Royal Belgian Institute for Space Aeronomy (BIRA–IASB)], reported on work focusing on the OMI and TROPOMI HCHO CDR and Huan Yu [BIRA–IASB)] reported harmonized OMI and TROPOMI cloud height datasets based on improved O2-O2 absorption retrieval algorithm.
Lok Lamsal [GSFC/UMBC, Goddard Earth Sciences Technology and Research (GESTAR) II], Henk Eskes, and Pepijn Veefkind [KNMI] reported on the OMI and TROPOMI NO2 CDRs – see Figure 4.
Si-Wan Kim [Yonsei University, South Korea] reported on OMI and TROPOMI long-term NO2 trends.
Figure 4. OMI nitrogen dioxide (NO2) time series bridging the first GOME mission (which flew on the European Remote Sensing Satellite–2 (ERS–2) from 1995–2011 with limited coverage after 2003) and measurements from the two currently operating missions – OMI (2004–present) and TROPOMI (2017–present) – offer consistent climate data records that allow for studying long-term changes. This example shows tropospheric NO2 column time series from three instruments over Phoenix, AZ. The overlap between the OMI and TROPOMI missions allows for intercomparison between the two, which is crucial to avoid continuity-gaps in multi-instrument time series. The ERS-2 (GOME) had a morning equator crossing time (10:30 AM), while Aura (OMI) and Metop (TROPOMI) have afternoon equator crossing times of 1:45 PM and 1:30 PM respectively. Figure credit: Lok Lamsal/GSFC/University of Maryland, Baltimore County (UMBC) Update on Aura’s Drifting Orbit
Bryan Duncan [GSFC—Aura Project Scientist] closed out the first day with a presentation summarizing predictions of Aura’s drifting orbit. Overall, the impact of Aura’s drift is expected to be minor, and the OMI and MLS teams will be able to maintain science quality data for most data products. He thanked the OMI/TROPOMI ST and user community for expressing their strong support for continuing Aura observations until the end of the Aura mission in mid–2026.
DAY TWO
The second day of the meeting focused on current and upcoming LEO and GEO Atmospheric Composition (AC) missions.
TROPOMI Mission and Data Product Updates
Veefkind presented an update on the TROPOMI mission, which provides continuation and enhancements for all OMI products. Tobias Borssdorf [Stichting Ruimte Onderzoek Nederland (SRON), or Netherlands Institute for Space Research] explained how TROPOMI, with its innovative shortwave infrared (SWIR) spectrometer, measures CH4 and carbon monoxide (CO). This approach continues measurements that began by the Measurements of Pollution in the Troposphere (MOPITT) instrument on Terra.
Hiren Jethva [NASA Airborne Science Program] and Torres presented new TROPOMI near-UV aerosol products, including a new aerosol layer optical centroid height product, which takes advantage of the TROPOMI extended spectral range – see Figure 5.
Figure 5. Global gridded (0.10° x 0.10°) composite map of aerosol layer optical centroid height (AH) retrieved from TROPOMI O2-B band observations from May–September 2023. Figure credit: Hiren Jethva/NASA Airborne Science Program GEMS–TEMPO–Sentinel-4 (UVN): A Geostationary Air Quality Constellation
TROPOMI global observations serve as a de facto calibration standard used to homogenize a new constellation of three missions that will provide AC observations for most of the Northern Hemisphere from GEO. Two of the three constellation members are already in orbit. Jhoon Kim [Yonsei University—PI] discussed the Geostationary Environmental Monitoring Spectrometer (GEMS), launched on February 19, 2020 aboard the Republic of Korea’s GEO-KOMPSAT-2B satellite. It is making GEO AC measurements over Asia. The GEMS team is working on validating measurements of NO2 diurnal variations using ground-based measurements from the PANDORA Global Network over Asia and aircraft measurements from the ASIA–AQ field campaign.
Liu discussed NASA’s Tropospheric Emission Monitoring of Pollution (TEMPO) spectrometer, launched on April 7, 2023, aboard a commercial INTELSAT 40E satellite. From its GEO vantage point, TEMPO can observe the Continental U.S., Southern Canada, Mexico, and the coastal waters of the Northwestern Atlantic and Northeastern Pacific oceans.
Gonzales Abad [SAO] presented the first measurements from TEMPO. He explained that TEMPO’s design is similar to GEMS, but GEMS includes an additional visible and near infrared (VNIR) spectral channel (540–740 nm) to measure tropospheric O3, O2, and water vapor (H2Ov). TEMPO can perform optimized morning scans, twilight scans, and scans with high temporal resolution (5–10 minutes) over selected regions. Abad reported that the TEMPO team released L1B spectra and the first provisional public L2 products (Version 3), including NO2, HCHO, and total column O3. Andrew Rollins [National Oceanic and Atmospheric Administration’s (NOAA) Chemical Sciences Laboratory (CSL)] reported that the TEMPO team is working on validation of provisional data using both ground-based data from PANDORA spectrometers and data collected during several different airborne campaigns completed during the summer of 2023 and compiled on the AGES+ website.
Ben Veihelmann [ESA’s European Space Research and Technology Center—PI] explained that ESA’s Copernicus Sentinel-4 mission will be the final member of the GEO AC constellation. Veefkind summarized the Sentinel-4 mission, which is expected to launch on the Meteosat Third Generation (MTG)-Sounder 1 (MTG-S1) platform in 2025. The mission is dedicated to measuring air quality and O3 over Europe and parts of the Atlantic and North Africa. Sentinel-4 will deploy the first operational UV-Vis-NIR (UVN) imaging spectrometer on a geostationary satellite. (Airbus will build UVN, with ESA providing guidance.) Sentinel-4 includes two instruments launched in sequence on MTG-S1 and MTG-S2 platforms designed to have a combined lifetime of 15 years. The mission by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) will operate Sentinel-4, and the Deutsches Zentrum für Luft- und Raumfahrt (DLR) or German Aerospace Center will be responsible for operational L2 processing.
These three GEO AC missions, along with the upcoming ESA/EUMETSAT/Copernicus LEO (morning orbit, 9:30 a.m.) Sentinel-5 (S5) mission, will complete a LEO–GEO satellite constellation that will enable monitoring of the most industrialized and polluted regions in the Northern Hemisphere into the 2030s. Sentinel-5 will not continue the OMI–TROPOMI data record in the early afternoon; however, it will be placed in the morning orbit and follow ESA’s Global Ozone Monitoring Experiment (GOME) and EUMETSAT GOME-2 missions. By contrast, GEO AC observations over the Southern Hemisphere are currently not available. Several presenters described ongoing projects for capacity building for LEO satellite air quality data uptake and emission monitoring in Africa and advocated for the new geostationary measurements.
Synergy with Other Current or Upcoming Missions
Attendees discussed the synergy between upcoming AC, GHG, and ocean color missions. Current trends in satellite AC measurements are toward increased spatial resolution and combined observations of short-lived reactive trace gases – which are important for air quality (AQ) monitoring – and long-lived GHG – which are important for climate monitoring and carbon cycle assessments. Some trace gases (e.g., O3 and CH4) are both polluters and GHG agents. Others [e.g., NO2 and sulfur dioxide (SO2 )] are aerosol [particulate matter (PM)] and O3 precursors and are used as proxies and spatial indicators for anthropogenic CO2 and CH4 emissions.
Yasjka Meijer [ESA—Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) Mission Scientist]) reviewed the plans for CO2M, which includes high-resolution measurements [~4 km2 (~1.5 mi2)] of CO2 , CH4 , and NO2.
Jochen Landgraf [SRON] described ESA’s new Twin Anthropogenic Greenhouse Gas Observers (TANGO) mission, which has the objective to measure CO2 , CH4 , and NO2 at even higher spatial resolution [~300 m (~984 ft)] using two small CubeSat spectrometers flying in formation.
Hiroshi Tanimoto [National Institute for Environmental Studies, Japan] described the Japan Aerospace Exploration Agency’s (JAXA) Global Observing SATellite for greenhouse gases and water cycle (GOSAT-GW) mission, which includes the Total Anthropogenic and Natural Emission mapping SpectrOmeter (TANSO-3) spectrometer to simultaneously measure CO2 , CH4, and NO2 with ~1–3 km (~0.6–1.8 mi) spatial resolution in focus mode. GOSAT-GW will also fly the Advanced Microwave Scanning Radiometer 3 (AMSR3).
Joanna Joiner [GSFC—Geostationary Extended Operations (GeoXO) Project Scientist and ACX Instrument Scientist] described the plans for the next-generation U.S. geosynchronous satellite constellation, which will consist of three satellites covering the full Earth disk: GEO-East, GEO-West, and GEO-Central. (By contrast, the current Geostationary Operational Environmental Satellite (GOES) series has two satellites: GOES–East and GOES–West.) GEO-Central will carry an advanced infrared sounder (GXS) for measuring vertical profiles of many trace gases, temperature and humidity, and a new UV-VIS spectrometer (ACX), which is a follow-on to TEMPO for AQ applications. Both GXS and ACX instruments will be built by BAE Systems, which acquired Ball Aerospace and Technology, and will also build the GeoXO ocean color spectrometer (OCX).
Andrew Sayer [UMBC] described NASA’s Plankton, Aerosols, Clouds, and ocean Ecosystem (PACE), which launched on February 8, 2024. The PACE payload includes a high-spatial resolution [~1 km (~0.6 mi) at nadir] Ocean Color Instrument (OCI), which is a UV-Vis-NIR spectrometer with discrete SWIR bands presenting additional opportunities for synergistic observations with the AC constellation. Sayer presented OCI “first light” aerosol data processed using the unified retrieval algorithm developed by Lorraine Remer [UMBC].
The second day concluded with a joint crossover session with NASA’s Health and Air Quality Applied Sciences Team (HAQAST) followed by a poster session. Several OMI–TROPOMI STM participants presented on a variety of topics that illustrate how OMI and TROPOMI data are being used to support numerous health and AQ applications. Duncan, who is also a member of HAQAST team, presented “20 years of health and air quality applications enabled by OMI data.” He highlighted OMI contributions to AQ and health applications, including NO2 trend monitoring, inferring trends of co-emitted species [e.g., CO2, CO, some Volatile Organic Compounds (VOCs)], validation of new satellite missions (e.g., TEMPO, PACE), and burden of disease studies.
DAY THREE
Discussions on the third day focused on advanced retrieval algorithms, leading to new products and new applications for OMI and TROPOMI data. Several presentations described applications of TROPOMI CH4 data and synergy with small satellites.
Advanced Retrieval Algorithms and New Data Products
Ilse Aben [SRON] described TROPOMI global detection of CH4 super-emitters using an automated system based on Machine Learning (ML) techniques – see Figure 6. Berend Schuit [SRON] provided additional detail on these methods. He introduced the TROPOMI CH4 web site to the meeting participants. He explained how TROPOMI global CH4 measurements use “tip-and-cue” dedicated satellites with much higher spatial resolution instruments [e.g., GHGSat with ~25-m (~82-ft) resolution] to scan for individual sources and estimate emission rates. Most CH4 super-emitters are related to urban areas and/or landfills, followed by plumes from gas and oil industries and coal mines.
Figure 6. Methane plume map produced by SRON shows TROPOMI large CH4 emission plumes for the week of the OMI–TROPOMI meeting (June 3–6, 2024). Figure credit: Itse Aben/Stichting Ruimte Onderzoek Nederland (SRON) Alba Lorente [Environmental Defense Fund—Methane Scientist] introduced a new MethaneSAT satellite launched in March 2024, which aims to fill the gap in understanding CH4 emissions on a regional scale [200 x 200 km2 (~77 x 77 mi2)] from at least 80% of global oil and gas production, agriculture, and urban regions. Alex Bradley [University of Colorado, Boulder] described improvements to TROPOMI CH4 retrievals that were achieved by correcting seasonal effects of changing surface albedo.
Daniel Jacob [Harvard University] presented several topics, including the highest resolution [~30 m (~98 ft)] NO2 plume retrievals from Landsat-8 – see Figure 7 – and Sentinel-2 imagers. He also discussed using a ML technique trained with TROPOMI data to improve NO2 retrievals from GEMS and modeling NO2 diurnal cycle and emission estimates. He introduced the ratio of ammonia (NH3) to NO2 (NH3/NO2) as an indicator of particulate matter with diameters less than 2.5 µm (PM2.5) nitrate sensitivity regime. Jacob emphasized the challenges related to satellite NO2 retrievals (e.g., accounting for a free-tropospheric NO2 background and aerosols).
Figure 7. Landsat Optical Land Imager (OLI) image, obtained on October 17, 2021 over Saudi Arabia, shows power plant exhaust, which contains nitrogen dioxide (NO2) drifting downwind from the sources (the two green circles are the stacks). The ultra-blue channel (430–450 nm) on OLI enables quantitative detection of NO2 in plumes from large point sources at 30-m (~98-ft) resolution. This provides a unique ability for monitoring point-source emissions of oxides of nitrogen (NOx). The two stacks in the image are separated by 2 km (~1.2 mi). Figure credit: Daniel Jacob – repurposed from a 2024 publication in Proceedings of the National Academies of Sciences (PNAS) Steffen Beirle [Max Planck Institute for Chemistry, Germany] explained his work to fit TROPOMI NO2 column measurements to investigate nitric oxide (NO) to NO2 processing in power plant plumes. Debra Griffin [Environment and Climate Change Canada (ECCC)] used TROPOMI NO2 observations and ML random forest technique to estimate NO2 surface concentrations. Sara Martinez-Alonso [NCAR] investigated geographical and seasonal variations in NO2 diurnal cycle using GEMS and TEMPO data. Ziemkecombined satellite O3 data to confirm a persistent low anomaly (~5–15%) in tropospheric O3 after 2020. Jethva presented advanced OMI and TROPOMI absorbing aerosol products. Yu described improved OMI and TROPOMI cloud datasets using the O2-O2 absorption band at 477 nm. Nicholas Parazoo [Jet Propulsion Laboratory (JPL)] described TROPOMI Fraunhofer line retrievals of red solar-induced chlorophyll fluorescence (SIF) near O2-B band (663–685 nm) to improve mapping of ocean primary productivity. Liyin He [Duke University] described using satellite terrestrial SIF data to study the effect of particulate pollution on ecosystem productivity.
New Applications
Zachary Fasnacht [SSAI] used OMI and TROPOMI spectra to train a neural network to gap-fill MODIS and Visible Infrared Imaging Radiometer Suite (VIIRS) ocean color data under aerosol, sun glint, and partly cloudy conditions. This ML method can also be applied to PACE OCI spectra. Anu-Maija Sundström [Finnish Meteorological Institute (FMI)] used OMI and TROPOMI SO2 and O3 data as proxies to study new particle formation events. Lindsey Anderson [University of Colorado, Boulder] described how she used TROPOMI NO2 and CO measurements to estimate the composition of wildfire emissions and their effect on forecasted air quality. Heesung Chong [SAO] applied OMI bromine oxide (BrO) retrievals to the NOAA operational Ozone Mapping and Profiling Suite Nadir Mapper (OMPS-NM) on joint NOAA–NASA Suomi-National Polar-orbiting Partnership (Suomi NPP) satellite with the possibility to continue afternoon measurements using similar OMPS-NM instruments on the four Joint Polar Satellite System missions (JPSS-1,-2,-3,-4) into the 2030s. (JPSS-1 and -2 are now in orbit and known as NOAA-20 and -21 respectively; JPSS-4 is planned for launch in 2027, with JPSS-3 currently targeted for 2032.)
Kim demonstrated the potential for using satellite NO2 and SO2 emissions as a window into socioeconomic issues that are not apparent by other methods. For example, she showed how OMI and TROPOMI data were widely used to monitor air quality improvements in the aftermath of COVID-19 lockdowns. (Brad Fisher [SSAI] presented a poster on a similar topic.)
Cathy Clerbaux [Center National d’Études Spatiale (CNES), or French Space Agency] showed how her team used TROPOMI NO2 data to trace the signal emitted by ships and used this information to determine how the shipping lanes through the Suez Canal changed in response to unrest in the Middle East. Iolanda Ialongo [FMI] showed a similar drop of NO2 emissions over Donetsk region due to the war in Ukraine. Levelt showed how OMI and TROPOMI NO2 data are used for capacity-building projects and for air quality reporting in Africa. She also advocated for additional geostationary AQ measurements over Africa.
DAY FOUR
Discussions on the final day focused on various methods of assimilating satellite data into air quality models for emission inversions and aircraft TEMPO validation campaigns. The meeting ended with Levelt giving her unique perspective on the OMI mission, as she reflected on more than two decades being involved with the development, launch, operation, and maintenance of OMI.
Assimilating Satellite Data into Models for Emissions
Brian McDonald [CSL] described advance chemical data assimilation of satellite data for emission inversions and the GReenhouse gas And Air Pollutants Emissions System (GRA2PES). He showed examples of assimilations using TROPOMI and TEMPO NO2 observations to adjust a priori emissions. He also showed that when TEMPO data are assimilated, NOx emissions adjust faster and tend to perform better at the urban scale. Adrian Jost [Max Planck Institute for Chemistry] described the ESA-funded World Emission project to improve pollutant and GHG emission inventories using satellite data. He showed examples of TROPOMI SO2 emissions from large-point sources and compared the data with bottom-up and NASA SO2 emissions catalogue.
Ivar van der Velde [SRON] presented a method to evaluate fire emissions using new satellite imagery of burned area and TROPOMI CO. Helene Peiro [SRON] described her work to combine TROPOMI CO and burned area information to compare the impact of prescribed fires versus wildfires on air quality in the U.S. She concluded that prescribed burning reduces CO pollution. Barbara Dix [University of Colorado, Boulder, Cooperative Institute for Research in Environmental Sciences] derived NOx emissions from U.S. oil and natural gas production using TROPOMI NO2 data and flux divergence method. She estimated TROPOMI CH4 emissions from Denver–Julesburg oil and natural gas production. Dix explained that the remaining challenge is to separate oil and gas emissions from other co-located CH4 sources. Ben Gaubert [NCAR, Atmospheric Chemistry Observations and Modeling] described nonlinear and non-Gaussian ensemble assimilation of MOPITT CO using the data assimilation research testbed (DART).
Andrew (Drew) Rollings [CSL] presented first TEMPO validation results from airborne field campaigns in 2023 (AGES+ ), including NOAA CSL Atmospheric Emissions and Reactions observed from Megacities to Marine Aeras (AEROMMA) and NASA’s Synergistic TEMPO Air Quality Science (STAQS) campaigns.
A Reflection on Twenty Years of OMI Observations
Levelt gave a closing presentation in which she reflected on her first involvement with the OMI mission as a young scientist back in 1998. This led to a collaboration with the international ST to develop the instrument, which was included as part of Aura’s payload when it launched in July 2004. She reminisced about important highlights from 2 decades of OMI, e.g., the 10-year anniversary STM at KNMI in 2014 (see “Celebrating Ten Years of OMI Observations,” The Earth Observer, May–Jun 2014, 26:3, 23–30), and the OMI ST receiving the NASA/U.S. Geological Survey Pecora award in 2018 and the American Meteorological Society’s Special award in 2021.
Levelt pointed out that in this combined OMI–TROPOMI meeting the movement towards using air pollution and GHG data together became apparent. She ended by saying that the OMI instrument continues to “age gracefully” and its legacy continues with the TROPOMI and LEO–GEO atmospheric composition constellation of satellites that were discussed during the meeting.
Conclusion
Overall, the second OMI–TROPOMI STM acknowledged OMI’s pioneering role and TROPOMI’s unique enhancements in measurements of atmospheric composition:
Ozone Layer Monitoring: Over the past two decades, OMI has provided invaluable data on the concentration and distribution of O3 in the Earth’s stratosphere. This data has been crucial for understanding and monitoring the recovery of the O3 layer following international agreements, such as the Montreal Protocol. Air Quality Assessment: OMI’s high-resolution measurements of air pollutants, such as NO2, SO2, and HCHO, have significantly advanced our understanding of air quality. This information has been vital for tracking pollution sources, studying their transport and transformation, and assessing their impact on human health and the environment. Climate Research: The data collected by OMI has enhanced our knowledge of the interactions between atmospheric chemistry and climate change. These insights have been instrumental in refining climate models and improving our predictions of future climate scenarios. Global Impact: The OMI instrument has provided near-daily global coverage of atmospheric data, which has been essential for scientists and policymakers worldwide. The comprehensive and reliable data from OMI has supported countless research projects and informed decisions aimed at protecting and improving our environment. OMI remains one of the most stable UV/Vis instruments over its two decades of science and trend quality data collection. The success of the OMI and TROPOMI instruments is a testament to the collaboration, expertise, and dedication of both teams.

Astrogram banner TIME Recognizes the Advanced Composite Solar Sail System
In October, the Advanced Composite Solar Sail System a project managed at NASA Ames, was recognized by TIME Magazine as a “Top Invention of 2024”! TIME Magazine also recognized two other NASA missions this year: Europa Clipper, and the Deep Space Optical Communications experiment.
The Advanced Composite Solar Sail System is a demonstration of technologies that enable spacecraft to “sail on sunlight,” using solar radiation for propulsion. Results from this mission could provide an alternative to chemical and electric propulsion systems and guide the design of future larger-scale spacecraft for space weather early warning satellites, near-Earth asteroid reconnaissance missions, or communications relays for crewed exploration missions at the Moon and Mars.
The Advanced Composite Solar Sail System a project managed at NASA Ames, was recognized by TIME Magazine as a “Top Invention of 2024.”NASA This twelve-unit (12U) CubeSat features a reflective sail held taut by composite booms made from flexible polymer and carbon fiber materials that are stiffer and lighter than previous designs. The square-shaped solar sail measures approximately 80 square meters, but the new boom technology could support future missions for solar sails up to 500 square meters.
The mission launched on April 23 via a Rocket Lab Electron rocket and met its primary objective in August by deploying the boom and sail system in space. Next, the team will attempt to demonstrate maneuverability in orbit using the sail.
Congratulations to the Advanced Composite Solar Sail System team and the Small Spacecraft Technology program office, based at Ames, for this well-earned recognition. Their contributions continue to push the boundaries of what we can achieve at NASA, and this acknowledgment highlights the capabilities and vision of our center.

NASA and Partners Scaling to New Heights in Air Traffic Management
by Hillary Smith
NASA, in partnership with AeroVironment and Aerostar, recently demonstrated a first-of-its-kind air traffic management concept that could pave the way for aircraft to safely operate at higher altitudes.
This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as an Upper-Class E traffic management, or ETM. There is currently no traffic management system or set of regulations in place for aircraft operating 60,000 feet and above. There hasn’t been a need for a robust traffic management system in this airspace until recently. That’s because commercial aircraft couldn’t function at such high altitudes due to engine constraints.
NASA and partners from Aerostar and AeroVironment discuss a simulation of a high-altitude air traffic management system in the Airspace Operations Lab at NASA Ames.NASA photo by Don Richey However, recent advancements in aircraft design, power, and propulsion systems are making it possible for high- altitude, long-endurance vehicles — such as balloons, airships, and solar aircraft — to coast miles above our heads, providing radio relay for disaster response, collecting atmospheric data, and more.
But before these aircraft can regularly take to the skies, operators must find a way to manage their operations without overburdening air traffic infrastructure and personnel.
“We are working to safely expand high-altitude missions far beyond what is currently possible,” said Kenneth Freeman, a subproject manager for this effort at NASA’s Ames Research Center in California’s Silicon Valley. “With routine, remotely piloted high-altitude operations, we have the opportunity to improve our understanding of the planet through more detailed tracking of climate change, provide internet coverage in underserved areas, advance supersonic flight research, and more.”
Current high-altitude traffic management is processed manually and on a case-by-case basis. Operators must contact air traffic control to gain access to a portion of the Class E airspace. During these operations, no other aircraft can enter this high-altitude airspace. This method will not accommodate the growing demand for high-altitude missions, according to NASA researchers.
To address this challenge, NASA and its partners have developed an ETM traffic management system that allows aircraft to autonomously share location and flight plans, enabling aircraft to stay safely separated.
During the recent traffic management simulation in the Airspace Operations Laboratory at Ames, data from multiple air vehicles was displayed across dozens of traffic control monitors and shared with partner computers off site.
This included aircraft location, health, flight plans and more. Researchers studied interactions between a slow fixed-wing vehicle from AeroVironment and a high-altitude balloon from Aerostar operating at stratospheric heights.
Each aircraft, connected to the ETM traffic management system for high altitude, shared location and flight plans with surrounding aircraft.
This digital information sharing allowed Aerostar and AeroVironment high-altitude vehicle operators to coordinate and deconflict with each other in the same simulated airspace, without having to gain approval from air traffic control.
Because of this, aircraft operators were able to achieve their objectives, including wireless communication relay.
This simulation represents the first time a traffic management system was able to safely manage a diverse set of high-altitude aircraft operations in the same simulated airspace.
Next, NASA researchers will work with partners to further validate this system through a variety of real flight tests with high-altitude aircraft in a shared airspace.
The Upper-Class E traffic management concept was developed in coordination with the Federal Aviation Administration and high-altitude platform industry partners, under NASA’s National Airspace System Exploratory Concepts and Technologies subproject led out of Ames.
Starship Super Heavy Breezes Through Wind Tunnel Testing at NASA Ames
by Lee Mohon
NASA and its industry partners continue to make progress toward Artemis III and beyond, the first crewed lunar landing missions under the agency’s Artemis campaign. SpaceX, the commercial Human Landing System (HLS) provider for Artemis III and Artemis IV, recently tested a 1.2% scale model of the Super Heavy rocket, or booster, in the transonic Unitary Plan Wind Tunnel at NASA Ames. The Super Heavy rocket will launch the Starship human landing system to the Moon as part of Artemis.
A 1.2% scale model of the Super Heavy rocket that will launch the Starship human landing system to the Moon for future crewed Artemis missions was recently tested at NASA Ames’ transonic wind tunnel, providing valuable information on vehicle stability when re-entering Earth’s atmosphere.NASA During the tests, the wind tunnel forced an air stream at the Super Heavy scale model at high speeds, mimicking the air resistance and flow the booster experiences during flight. The wind tunnel subjected the Super Heavy model, affixed with pressure-measuring sensors, to wind speeds ranging from Mach .7, or about 537 miles per hour, to Mach 1.4, or about 1,074 miles per hour. Mach 1 is the speed that sound waves travel, or 761 miles per hour, at sea level.
Engineers then measured how Super Heavy model responded to the simulated flight conditions, observing its stability, aerodynamic performance, and more. Engineers used the data to update flight software for flight 3 of Super Heavy and Starship and to refine the exterior design of future versions of the booster. The testing lasted about two weeks and took place earlier in 2024.
After Super Heavy completes its ascent and separation from Starship HLS on its journey to the Moon, SpaceX plans to have the booster return to the launch site for catch and reuse. The Starship HLS will continue on a trajectory to the Moon.
To get to the Moon for the Artemis missions, astronauts will launch in NASA’s Orion spacecraft aboard the SLS (Space Launch System) rocket from the agency’s Kennedy Space Center in Florida. Once in lunar orbit, Orion will dock with the Starship HLS or with Gateway. Once the spacecraft are docked, the astronauts will move from Orion or Gateway to the Starship HLS, which will bring them to the surface of the Moon. After surface activities are complete, Starship will return the astronauts to Orion or Gateway waiting in lunar orbit. The astronauts will transfer to Orion for the return trip to Earth.
With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

NASA Begins New Deployable Solar Array Tech Demo on Pathfinder Spacecraft
by Gianine Figliozzi
NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown below is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission.
Payload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet (one meter) away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations.
A test image of Earth taken by NASA’s Pathfinder Technology Demonstrator-4’s onboard camera. The camera will capture images of the Lightweight Integrated Solar Array and anTenna upon deployment.NASA Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array.
“The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said Dr. John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”
The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array.
The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. NASA’s Marshall Space Flight Center in Huntsville, Alabama designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center in California’s Silicon Valley and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph.

Faces of NASA – Ames’ Dr. Donald Mendoza, Chief Engineer
“From my earliest childhood, flight had always captivated me. I lived out in the boonies and the farmlands, so I didn’t have neighbors to go and play with. If I wasn’t working, I was left to my own devices, and often, I would just be captivated by the wildlife and in particular, the birds of prey that I would see.
Dr. Donald Menodoza, Chief Engineer, NASA Engineering and Safety Center at Ames.NASA photo by Dominic Hart “To me, they represented a freedom of some kind or another. These birds and the view they have — they can take in so much. So, from that point on, I knew I wanted to be involved in flight and aviation.
“I [enjoyed] all things flight, all things spaceflight. I couldn’t get enough of it. I became an avid reader, whereas before, I wasn’t much of a reader. I couldn’t get enough material to read about my heroes from flight and space. They became my role models and the path that they took involved, at some point or another, a pretty rigorous education and dedication to doing well academically, physically, or athletically. So, I threw myself into that entire sort of mindset.
“When I was working for the Air Force, I was able to fly and work on aircraft that I would dream about, looking at in the magazines Aviation Week and Space Technology. Here they are, right in front of me.
“… So, my career has been as close as possible to that of a flight test engineer. And then, right on the heels of being captivated by atmospheric flight, working in human spaceflight has put me over the Moon.”
—Dr. Donald Mendoza, Chief Engineer, NASA Engineering & Safety Center, NASA’s Ames Research Center

We Are All Made of Cells: Space and the Immune System
by Rachel Hoover
Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms.
But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley.
Bone cells NASA/Eduardo Almeida and Cassie Juran “Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’”
O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks.
“The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.”

Joseph Wu, Dilip Thomas and Xu Cao, Stanford Cardiovascular Institute O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond.
“It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.”
During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth.
“I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.”
When O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity.
O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.
