Illustration of NASA’s BioSentinel spacecraft as it enters a heliocentric orbit. BioSentinel collected data during the May 2024 geomagnetic storm that hit Earth to learn more about the impacts of radiation in deep space.NASA/Daniel Rutter In May 2024, a geomagnetic storm hit Earth, sending auroras across the planet’s skies in a once-in-a-generation light display. These dazzling sights are possible because of the interaction of coronal mass ejections – explosions of plasma and magnetic field from the Sun – with Earth’s magnetic field, which protects us from the radiation the Sun spits out during turbulent storms. But what might happen to humans beyond the safety of Earth’s protection? This question is essential as NASA plans to send humans to the Moon and on to Mars. During the May storm, the small spacecraft BioSentinel was collecting data to learn more about the impacts of radiation in deep space. “We wanted to take advantage of the unique stage of the solar cycle we’re in – the solar maximum, when the Sun is at its most active – so that we can continue to monitor the space radiation environment,” said Sergio Santa Maria, principal investigator for BioSentinel’s spaceflight mission at NASA’s Ames Research Center in California’s Silicon Valley. “These data are relevant not just to the heliophysics community but also to understand the radiation environment for future crewed missions into deep space.” BioSentinel – a small satellite about the size of a cereal box – is currently over 30 million miles from Earth, orbiting the Sun, where it weathered May’s coronal mass ejection without protection from a planetary magnetic field. Preliminary analysis of the data collected indicates that even though this was an extreme geomagnetic storm, that is, a storm that disturbs Earth’s magnetic field, it was considered just a moderate solar radiation storm, meaning it did not produce a great increase in hazardous solar particles. Therefore, such a storm did not pose any major issue to terrestrial lifeforms, even if they were unprotected as BioSentinel was. These measurements provide useful information for scientists trying to understand how solar radiation storms move through space and where their effects – and potential impacts on life beyond Earth – are most intense. NASA’s Solar Dynamics Observatory captured this image of a solar flare on May 11, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares.NASA/SDO The original mission of BioSentinel was to study samples of yeast in deep space. Though these yeast samples are no longer alive, BioSentinel has adapted and continues to be a novel platform for studying the potential impacts of deep space conditions on life beyond the protection of Earth’s atmosphere and magnetosphere. The spacecraft’s biosensor instrument collects data about the radiation in deep space. Over a year and a half after its launch in Nov. 2022, BioSentinel retreats farther away from Earth, providing data of increasing value to scientists. “Even though the biological part of the BioSentinel mission was completed a few months after launch, we believe that there is significant scientific value in continuing with the mission,” said Santa Maria. “The fact that the CubeSat continues to operate and that we can communicate with it, highlights the potential use of the spacecraft and many of its subsystems and components for future long-term missions beyond low Earth orbit.” When we see auroras in the sky, they can serve as a stunning reminder of all the forces we cannot see that govern our cosmic neighborhood. As NASA and its partners seek to understand more about space environments, platforms like BioSentinel are essential to learn more about the risks of surviving beyond Earth’s sphere of protection.

4 min read Pioneer of Change: America Reyes Wang Makes NASA Space Biology More Open America Reyes Wang, the lead of the the Space Biology Biospecimen Sharing Program at NASA’s Ames Research Center in California’s Silicon Valley, stands beside a spacesuit display. Photo courtesy of America Reyes Wang As humans return to the Moon and push on toward Mars, scientists are ramping up research into the effects of space on the body to make sure astronauts stay healthy on longer missions. This research often involves spaceflight studies of rodents, insects, and other models in orbiting laboratories such as the International Space Station. However, space-related biological samples are difficult to get, meaning that researchers who want to study space biology are frequently out of luck. America Reyes Wang, a KBR employee and the lead of the Space Biology Biospecimen Sharing Program at NASA’s Ames Research Center in California’s Silicon Valley, oversees the team that has changed that. Birthed from an initiative first pioneered in the 1960s, the Biospecimen Sharing Program collects samples and data from NASA non-human space biology studies and makes them available in the public, open NASA Open Science Data Repository (OSDR). To derive the most benefit from the precious few biology studies taking place in space, Reyes Wang arranges collaborations on space biology dissections with NASA-funded researchers so that her team can collect and preserve unutilized biospecimens for others to use. Outside researchers can request the samples to study in person by writing and submitting proposals. Once analyzed, researchers share their data back with the NASA OSDR for other investigators to access and study. The ethos of open science is central to Reyes Wang’s approach to her work. “The samples that we work with are so precious,” she said. “To me, it’s a no-brainer — why not share what we can share?” America Reyes Wang wears personal protective equipment (PPE) while working on an activity for NASA’s Biospecimen Sharing Program. Photo courtesy of America Reyes Wang Reyes Wang aspired to work in the scientific or medical field from a young age, driven by her desire to help people. Her father, who was born in El Salvador and dreamed of being an astronaut after watching the 1969 Moon landing, inspired Reyes Wang to fall in love with space. She also credited her Salvadoran and Mexican family with teaching her the value of understanding different experiences. “To me, being Hispanic, especially as a Latina in STEM, means recognizing and building upon the hard work and sacrifices of those who came before me, as well as extending a helping hand to those around me for the betterment of us all,” Reyes Wang said. “It also means enjoying and sharing our vibrant cultures.” As a student at Stanford University, Reyes Wang conducted neurobiology research with rodents, but assumed she would have to choose her love of biology over her love of space. The field of space biology allowed her to combine those interests. Having quietly dreamed of working for NASA for years, she was also thrilled to find that she could work on NASA missions as a space biologist. If we want to keep up with the pace of humanity’s aspirations to travel further and for longer … open science is one of the best tools we have for achieving those dreams. America Reyes Wang Biospecimen Sharing Program Lead Reyes Wang first found a role supporting NASA as an experiment support scientist for the agency’s Rodent Research Program. While she no longer facilitates research on the International Space Station in her current position, she uses her scientific expertise and collaborative outlook to guide the Biospecimen Sharing Program in a direction that will most help advance science. Despite space biology’s status as a relatively niche field, Reyes Wang has noted its tremendous impact on the biological sciences, medicine, and technology as a whole. For example, spaceflown biological samples are often used to investigate diseases that affect people on Earth. Reyes Wang’s involvement in accelerating these studies captures her long-held desire to help people. “Open science gives the world an opportunity to get these important answers much more quickly,” Reyes Wang said. “If we want to keep up with the pace of humanity’s aspirations to travel further and for longer, we need to pick up the pace when it comes to getting the answers, and I think open science is one of the best tools we have for achieving those dreams.” By Lauren Leese Web Content Strategist for the Office of the Chief Science Data Officer Share Details Last Updated Sep 26, 2024 Related Terms Biological & Physical Sciences Open Science Space Biology Explore More 1 min read Women in Astronomy Citizen Science Webinar This Thursday Article 3 days ago 4 min read NASA Awards 15 Grants to Support Open-Source Science Article 1 month ago 2 min read Geospatial AI Foundation Model Team Receives NASA Marshall Group Achievement Award Article 1 month ago Keep Exploring Discover Related Topics Missions Humans in Space Climate Change Solar System View the full article

Completion of a critical water system infrastructure project helps ensure the site can continue that frontline work moving forward. “The infrastructure at NASA Stennis is absolutely critical for rocket engine testing for the agency and commercial companies,” said NASA project manager Casey Wheeler. “Without our high pressure industrial water system, testing does not happen. Installing new underground piping renews the lifespan and gives the center a system that can be operated for the foreseeable future, so NASA Stennis can add to its nearly six decades of contributions to space exploration efforts.” The high pressure industrial water system delivers hundreds of thousands of gallons of water per minute through underground pipes to cool rocket engine exhaust and provide fire suppression capabilities during testing. Without the water flow, the engine exhaust, reaching as hot as 6,000 degrees Fahrenheit, could melt the test stand’s steel flame deflector. Each test stand also features a FIREX system that holds water in reserve for use in the event of a mishap or fire. During SLS (Space Launch System) core stage testing, water also was used to create a “curtain” around the test hardware, dampening the high levels of noise generated during hot fire and lessening the video-acoustic impact that can cause damage to infrastructure and the test hardware. Prior to the system upgrade, the water flow was delivered by the site’s original piping infrastructure built in the 1960s. However, that infrastructure had well exceeded its expected 30-year lifespan. Scope of the Project The subsequent water system upgrade was planned across multiple phases over a 10-year span. Crews worked around ever-changing test schedules to complete three major projects representing more than $50 million in infrastructure investment. “Many people working the construction jobs for these projects are from the Gulf Coast area, so it has created jobs and work for the people doing the construction,” Wheeler said. “Some of the specialty work has had people coming in from all over the country, as well as vendors and suppliers that are supplying the materials, so that has an economic impact here too.” Crews started by replacing large sections of piping, including a 96-inch line, from the 66-million-gallon onsite reservoir to the Thad Cochran (B-1/B-2) Test Stand. This phase also included the installation of a new 25,000-gallon electric pump at the High Pressure Industrial Water Facility to increase water flow capacity. The upgrades were critical for NASA Stennis to conduct Green Run testing of the SLS core stage in 2020-21 ahead of the successful Artemis I launch. Work in the A Test Complex followed with crews replacing sections of 75-inch piping from the water plant and installing several new 66-inch gate valves. In the final phase, crews used an innovative approach to install new steel liners within existing pipes leading to the Fred Haise Test Stand (formerly A-1 Test Stand). The work followed NASA’s completion of a successful RS-25 engine test campaign last April for future Artemis missions to the Moon and beyond. The stand now is being prepared to begin testing of new RS-25 flight engines. Overall, the piping project represents a significant upgrade in design and materials. The new piping is made from carbon steel, with protective linings to prevent corrosion and gate valves designed to be more durable. Importance of Water It is hard to overstate the importance of the work to ensure ongoing water flow. For a typical 500-second RS-25 engine test on the Fred Haise Test Stand, around 5 million gallons of water is delivered from the NASA Stennis reservoir through a quarter-of-a-mile of pipe before entering the stand to supply the deflector and cool engine exhaust. “Without water to cool the deflector and the critical parts of the test stand that will get hot from the hot fire itself, the test stand would need frequent corrective maintenance,” Wheeler said. “This system ensures the test stands remain in a condition where continuous testing can happen.” Share Details Last Updated Sep 26, 2024 EditorNASA Stennis CommunicationsContactC.

A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of light. In the foreground, to the right is a binary star system. The system is far from the black hole, but in the vicinity of the jet. In the system an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. As the hydrogen accumulates on the surface of the dwarf, it reaches a tipping point where it explodes like a hydrogen bomb. Novae frequently pop-off throughout the giant galaxy of 1 trillion stars, but those near the jet seem to explode more frequently. So far, it’s anybody’s guess why black hole jets enhance the rate of nova eruptions. NASA, ESA, Joseph Olmsted (STScI) Download this image In a surprise finding, astronomers using NASA’s Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but apparently in a dangerous neighborhood nearby. The finding is confounding researchers searching for an explanation. “We don’t know what’s going on, but it’s just a very exciting finding,” said lead author Alec Lessing of Stanford University. “This means there’s something missing from our understanding of how black hole jets interact with their surroundings.” A nova erupts in a double-star system where an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. When the dwarf has tanked up a mile-deep surface layer of hydrogen that layer explodes like a giant nuclear bomb. The white dwarf isn’t destroyed by the nova eruption, which ejects its surface layer and then goes back to siphoning fuel from its companion, and the nova-outburst cycle starts over again. Hubble found twice as many novae going off near the jet as elsewhere in the giant galaxy during the surveyed time period. The jet is launched by a 6.5-billion-solar-mass central black hole surrounded by a disk of swirling matter. The black hole, engorged with infalling matter, launches a 3,000-light-year-long jet of plasma blazing through space at nearly the speed of light. Anything caught in the energetic beam would be sizzled. But being near its blistering outflow is apparently also risky, according to the new Hubble findings. A Hubble Space Telescope image of the giant galaxy M87 shows a 3,000-light-year-long jet of plasma blasting from the galaxy’s 6.5-billion-solar-mass central black hole. The blowtorch-like jet seems to cause stars to erupt along its trajectory. These novae are not caught inside the jet, but are apparently in a dangerous neighborhood nearby. During a recent 9-month survey, astronomers using Hubble found twice as many of these novae going off near the jet as elsewhere in the galaxy. The galaxy is the home of several trillion stars and thousands of star-like globular star clusters. NASA, ESA, STScI, Alec Lessing (Stanford University), Mike Shara (AMNH); Acknowledgment: Edward Baltz (Stanford University); Image Processing: Joseph DePasquale (STScI) Download this image The finding of twice as many novae near the jet implies that there are twice as many nova-forming double-star systems near the jet or that these systems erupt twice as often as similar systems elsewhere in the galaxy. “There’s something that the jet is doing to the star systems that wander into the surrounding neighborhood. Maybe the jet somehow snowplows hydrogen fuel onto the white dwarfs, causing them to erupt more frequently,” said Lessing. “But it’s not clear that it’s a physical pushing. It could be the effect of the pressure of the light emanating from the jet. When you deliver hydrogen faster, you get eruptions faster. Something might be doubling the mass transfer rate onto the white dwarfs near the jet.” Another idea the researchers considered is that the jet is heating the dwarf’s companion star, causing it to overflow further and dump more hydrogen onto the dwarf. However, the researchers calculated that this heating is not nearly large enough to have this effect. “We’re not the first people who’ve said that it looks like there’s more activity going on around the M87 jet,” said co-investigator Michael Shara of the American Museum of Natural History in New York City. “But Hubble has shown this enhanced activity with far more examples and statistical significance than we ever had before.” Shortly after Hubble’s launch in 1990, astronomers used its first-generation Faint Object Camera (FOC) to peer into the center of M87 where the monster black hole lurks. They noted that unusual things were happening around the black hole. Almost every time Hubble looked, astronomers saw bluish “transient events” that could be evidence for novae popping off like camera flashes from nearby paparazzi. But the FOC’s view was so narrow that Hubble astronomers couldn’t look away from the jet to compare with the near-jet region. For over two decades, the results remained mysteriously tantalizing. Compelling evidence for the jet’s influence on the stars of the host galaxy was collected over a nine-month interval of Hubble observing with newer, wider-view cameras to count the erupting novae. This was a challenge for the telescope’s observing schedule because it required revisiting M87 precisely every five days for another snapshot. Adding up all of the M87 images led to the deepest images of M87 that have ever been taken. In a surprise finding, astronomers, using NASA’s Hubble Space Telescope have discovered that the jet from a supermassive black hole at the core of M87, a huge galaxy 54 million light years away, seems to cause stars to erupt along its trajectory. NASA’s Goddard Space Flight Center; Lead Producer: Paul Morris Hubble found 94 novae in the one-third of M87 that its camera can encompass. “The jet was not the only thing that we were looking at — we were looking at the entire inner galaxy. Once you plotted all known novae on top of M87 you didn’t need statistics to convince yourself that there is an excess of novae along the jet. This is not rocket science. We made the discovery simply by looking at the images. And while we were really surprised, our statistical analyses of the data confirmed what we clearly saw,” said Shara. This accomplishment is entirely due to Hubble’s unique capabilities. Ground-based telescope images do not have the clarity to see novae deep inside M87. They cannot resolve stars or stellar eruptions close to the galaxy’s core because the black hole’s surroundings are far too bright. Only Hubble can detect novae against the bright M87 background. Novae are remarkably common in the universe. One nova erupts somewhere in M87 every day. But since there are at least 100 billion galaxies throughout the visible universe, around 1 million novae erupt every second somewhere out there. The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard.

On Sept. 9 and 10, scientists and engineers tested NASA’s LEMS (Lunar Environment Monitoring Station) instrument suite in a “sandbox” of simulated Moon regolith at the Florida Space Institute’s Exolith Lab at the University of Central Florida in Orlando. Lunar regolith is a dusty, soil-like material that coats the Moon’s surface, and researchers wanted to observe how the material would interact with LEMS’s hardware, which is being developed to fly to the Moon with Artemis III astronauts in late 2026. Designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, LEMS is one of three science payloads chosen for development for Artemis III, which will be the first mission to land astronauts on the lunar surface since 1972. The LEMS instrument package can operate both day and night. It will carry two University of Arizona-built seismometers to the surface to perform long-term monitoring for moonquakes and meteorite impacts.

Emory Gaddis Leveraging High Resolution PlanetScope Imagery to Quantify oil slick Spatiotemporal Variability in the Santa Barbara Channel Emory Gaddis, Colgate University Located within the Santa Barbara Channel of California, Coal Oil Point is one of the world’s largest hydrocarbon seep fields. The area’s natural hydrocarbon seepage and oil production have sustained both scientific interest and commercial activity for decades. Historically, indigenous peoples in the region utilized the naturally occurring tar for waterproofing baskets, establishing early evidence of the natural presence of hydrocarbons long before modern oil extraction began. Gaseous hydrocarbons are released from the marine floor through the process of seeping, wherein a buildup of reservoir pressure relative to hydrostatic pressure causes bubbles, oily bubbles, and droplets to rise to the surface. This hydrocarbon seepage is a significant source of Methane CH4—a major greenhouse gas––emissions into the atmosphere. Current limitations of optical remote sensing of oil presence and absence in the ocean leverage geometrical as well as biogeochemical factors and include changes in observed sun glint, sea surface damping, and wind roughening due to changes in surface oil concentrations. We leverage high-resolution (3m) surface reflectance observations obtained from PlanetScope to construct a time series of oil slick surface area spanning 2017 to 2023 within the Coal Oil Point seep field. Our initial methods are based on manual annotations performed within ArcGIS-Pro. We assess potential relationships between wind speed and oil slick surface area to support a sensitivity analysis of our time series. Correcting for confounding outside factors (e.g., wind speed) that modify oil slick surface area improves determination of oil slick surface area and helps test for changes in natural seepage rates and whether anthropogenic activities, such as oil drilling, alter natural oil seepage. Future investigations into oil slick chemical properties and assessing how natural seepage impacts marine and atmospheric environments (e.g., surface oil releases methane into the atmosphere) can help to inform the science of optimizing oil extraction locations. Rachel Emery Investigating Airborne LiDAR Retrievals of an Emergent South African Macroalgae Rachel Emery, The University of Oklahoma Right now, the world is facing an unprecedented biodiversity crisis, with areas of high biodiversity at the greatest risk of species extinction. One of these biodiversity hotspots, the Western Cape Province of South Africa, features one of the world’s largest unique marine ecosystems due to the extensive growth of canopy forming kelps, such as Macrocystis and Ecklonia, which provide three-dimensional structure important for fostering biodiversity and productivity. Canopy-forming kelps face increasing threats by marine heatwaves and pollution related to climate change and local water quality perturbation. Though these ecosystems can be monitored using traditional field surveying methods, remote sensing via airborne and satellite observations support improved spatial coverage and resample rates, plus extensive historical continuity for tracking multidecadal scale changes. Passive remote sensing observations—such as those derived using observations from NASA’s Airborne Visible-Infrared Imaging Spectrometer – Next Generation (AVIRIS-NG) —provide high resolution, hyperspectral imagery of oceanic environments anticipated to help characterize community dynamics and quantify macroalga physiological change. Active remote sensing observations, e.g., Light Detection and Ranging (LiDAR), are less understood in terms of applications to marine ecosystems, but are anticipated to support novel observations of vertical structure not supported using passive aquatic remote sensing. Here we investigate the potential to observe an emergent canopy-forming macroalgae (i.e., Ecklonia, which can extend more than a decimeter above the ocean’s surface) using NASA’s Land, Vegetation, and Ice sensor (LVIS), which confers decimeter-scale vertical resolution. We validate LVIS observations using matchup observations from AVIRIS-NG imagery to test whether LiDAR remote sensing can improve monitoring of emergent kelps in key biodiversity regions such as the Western Cape. Brayden Lipscomb Vertical structure of the aquatic light field based on half a century of oceanographic records from the southern California Current Brayden Lipscomb, West Virginia University Understanding the optical properties of marine ecosystems is crucial for improving models related to oceanic productivity. Models relating satellite observations to oceanic productivity or subsurface (e.g., benthic) light availability often suffer from uncertainties in parameterizing vertical structure and deriving columnar parameters from surface observations. The most accurate models use in situ station data, minimizing assumptions such as atmospheric optical thickness or water column structure. For example, improved accuracy of satellite primary productivity models has previously been demonstrated by incorporating information on vertical structure obtained from gliders and floats. We analyze vertical profiles in photosynthetically available radiation (PAR) obtained during routine surveys of the southern California Current system by the California Cooperative Oceanic Fisheries Investigation (CalCOFI). We find that depths of 1% and 10% light availability show coherent log-linear relationships with attenuation measured near surface (i.e., within the first 10 m), despite vertical variability in water column constituent concentrations and instrumentation challenges related to sensitivity, self-shading, and ship adjacency. Our results suggest that subsurface optical properties can be more reliably parameterized from near-surface measurements than previously understood. Dominic Bentley Comparing SWOT and PACE Satellite Observations to Assess Modification of Phytoplankton Biomass and Assemblage by North Atlantic Ocean Eddies Dominic Bentley, Pennsylvania State University Upwelling is the shoaling of the nutricline, thermocline, and isopycnals due to advection by eddies of the surface ocean layer. This shoaling effect leads to an increase in the productivity of algal blooms in a given body of water. Mesoscale to deformation scale eddy circulation modulates productivity based on latitude, season, direction, and other physical factors. However, many processes governing the effects of eddies on the ocean microbial environment remain unknown due to limitations in observations linking eddy strength and direction with productivity and ocean biogeochemistry. Currently, satellites are the only ocean observing system that allows for broad spatial coverage with high resample rates, albeit with limitations due to cloud obstructions (including storms that may stimulate productivity) and to observations being limited to the near-surface. A persisting knowledge gap in oceanography stems from limitations in the spatial resolution of observations resolving submesoscale dynamics. The recent launch of the Surface Water and Ocean Topography (SWOT) mission in December of 2022 supports observations of upper-ocean circulation with increased resolution relative to legacy missions (e.g. TOPEX/Poseidon, Jason-1, OSTM/Jason-2). Meanwhile, the launch of the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite in February of 2024 is anticipated to improve knowledge of ocean microbial ecosystem dynamics. We match up SWOT observations of sea surface height (SSH) anomalies—informative parameters of eddy vorticity—with PACE observations of surface phytoplankton biomass and community composition to relate the distribution of phytoplankton biomass and assemblage structure to oceanic eddies in the North Atlantic. We observe higher concentrations of Chlorophyll a (Chla) within SSH minima indicating the stimulation of phytoplankton productivity by cyclonic features associated with upwelling-driven nutrient inputs. Abigail Heiser Assessing EMIT observations of harmful algae in the Salton Sea Abigail Heiser, University of Wisconsin- Madison In 1905, flooding from the Colorado River gave rise to what would become California’s largest lake, the Salton Sea. Today, the majority of its inflow is sourced from agricultural runoff, which is rich in fertilizers and pollutants, leading to elevated lake nutrient levels that fuel harmful algal blooms (HAB) events. Increasingly frequent HAB events pose ecological, environmental, economic, and health risks to the region by degrading water quality and introducing environmental toxins. Using NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) imaging spectrometer we apply two hyperspectral aquatic remote sensing algorithms; cyanobacteria index (CI) and scattering line height (SLH). These algorithms detect and characterize spatiotemporal variability of cyanobacteria, a key HAB taxa. Originally designed to study atmospheric mineral dust, EMIT’s data products provide novel opportunities for detailed aquatic characterizations with both high spatial and high spectral resolution. Adding aquatic capabilities for EMIT would introduce a novel and cost-effective tool for monitoring and studying the drivers and timing of HAB onset, to improve our understanding of environmental dynamics. Emma Iacono Reassessing multidecadal trends in Water Clarity for the central and southern California Current System Emma Iacono, North Carolina State University Over the past several decades, the world has witnessed a steady rise in average global temperatures, a clear indication of the escalating effects of climate change. In 1990, Andrew Bakun hypothesized that unequal warming of sea and land surface temperatures would increase pressure gradients and lead to rising rates of alongshore upwelling within Eastern Boundary Currents, including the California Current System (CCS). An anticipated increase in upwelling-favorable winds would have profound implications for the productivity of the CCS, wherein upwelled waters supply nutrient injections that sustain and fuel coastal ocean phytoplankton stocks. Increasing upwelling, therefore, is anticipated to increase the turbidity of the upper ocean, corresponding with greater phytoplankton concentrations. Historical observations of turbidity are supported by observations obtained using a Secchi Disk, i.e., an opaque white instrument lowered into the water column. Observations of Secchi depth—or the depth at which light reflected from the Secchi Disk is no longer visible from the surface—provide a quantification of light penetration into the euphotic zone. The shoaling, or shallowing, of Secchi disk depths was previously reported for inshore, transition, and offshore waters of the central and southern CCS for historical observations spanning 1969 – 2007. Here, we reassess Secchi disk depths during the subsequent period spanning 2007 to 2021 and test for more recent changes in water clarity. Additionally, we evaluate the seasonality and spatial patterns of Secchi disk trends to test for potential changes to oceanic microbial ecology. Indications of long-term trends in some of the coastal domains assessed were found. Generally, our findings suggest a reversal of the trends previously reported. In particular, increases in water clarity likely associated with a recent marine heatwave (MHW) may be responsible for recent changes in Secchi disk depth observations, illustrating the importance of MHW events for modifying the CCS microbial ecosystem.

NASA Ames/Milan Loiacono Faculty Advisor: Dr. Donald Blake, University of California, Irvine Graduate Mentor: Katherine Paredero, Georgia Institute of Technology Katherine Paredero, Graduate Mentor Katherine Paredero, graduate student mentor for the 2024 SARP West Whole Air Sampling (WAS) group, provides an introduction for each of the group members and shares behind-the scenes moments from the internship. Mikaela Vaughn Urban Planning Initiative: Investigation of Isoprene Emissions by Tree Species in the LA Basin Mikaela Vaughn, Virginia Commonwealth University Elevated ozone concentrations have been a concern in Southern California for decades. The interaction between volatile organic compounds (VOC) and nitrous oxides (𝑁𝑂!) in the presence of sunlight leads to enhanced formation of tropospheric ozone (𝑂”) and secondary organic aerosols (SOA). This can lead to increased health hazards, exposing humans to aerosols that can enter and be absorbed by the lungs, as well as a warming effect caused by ozone’s role as a greenhouse gas in the lower levels of the atmosphere. This study will focus on a VOC that is of particular interest, isoprene, which has an atmospheric lifetime of one hour, making it highly reactive in the presence of the hydroxyl radical (OH) and resulting in rapid ozone formation. Isoprene is a biogenic volatile organic compound (BVOC) emitted by vegetation as a byproduct of photosynthesis. This BVOC has been overlooked but should be investigated further because of its potential to form large sums of ozone. In this study the reactivity of isoprene with OH dominated ozone formation as compared to other VOCs. Ambient isoprene concentrations were measured aboard NASA’s airborne science laboratory (King Air B200) along with whole air sampling canisters. Additionally, isoprene emissions of varying tree species, with one to three samples per type, were compared to propose certain trees to plant in urban areas. Results indicated that Northern Red Oaks and the Palms family emitted the most isoprene out of the nineteen species documented. The species with the lowest observed isoprene emissions was the Palo Verde and the Joshua trees. The difference in isoprene emissions between the Northern Red Oak and Joshua trees is approximately by a factor of 45. These observations show the significance of considering isoprene emissions when selecting tree species to plant in the LA Basin to combat tropospheric ozone formation. Joshua Lozano VOC Composition and Ozone Formation Potential Observed Over Long Beach, California Joshua Lozano, Sonoma State University Volatile organic compounds (VOCs), when released into the atmosphere, undergo chemical reactions in the presence of sunlight that can generate tropospheric ozone, which can have various health effects. We can gauge this ozone formation by multiplying the observed mixing ratios of VOCs by their respective rate constants (with respect to OH radicals). The OH radical reacts very quickly in the atmosphere and accounts for a large sum of ozone formation from VOCs as a result, giving us an idea of the ozone formation potential (OFP) for each VOC. In this study, we investigate observed mixing ratios of VOCs in order to estimate their contribution to OFP over Long Beach, California. The observed species of VOCs with the highest mixing ratios differs from the observed species with the highest OFP, which highlights that higher mixing ratios of certain VOCs in the atmosphere do not necessarily equate to a higher contribution to ozone formation. This underscores the importance of understanding mixing ratios of VOC species and their reaction rates with OH to gauge impacts on ozone formation. In the summer there were significantly lower VOC concentrations compared to the winter, which was expected because of differences in boundary layer height within the seasons. Additionally, a decrease in average mixing ratios was observed between the summer of 2014 and the summer of 2022. A similar trend was observed in OFP, but by a much smaller factor. This may indicate that even though overall VOC emissions are decreasing in Long Beach, the species that dominate in recent years have a higher OFP. This research provides a more comprehensive view of how VOCs contribute to air quality issues across different seasons and over time, stressing the need for targeted strategies to mitigate ozone pollution based on current and accurate VOC composition and reactivity. Sean Breslin Investigating Enhanced Methane and Ethane Emissions over the Long Beach Airport Sean Breslin, University of Delaware As climate change continues to worsen, the investigation and tracking of greenhouse gas emissions has become increasingly important. Methane, the second most impactful greenhouse gas, has accounted for over 20% of planetary warming since preindustrial times. Methane emissions primarily originate from biogenic and thermogenic sources, such as dairy farms and natural gas extraction. Ethane, an abundant hydrocarbon emitted from biomass burning and natural gas, contributes to the formation of tropospheric ozone. The data for this project was collected in December 2021 and June 2022 aboard the DC-8 aircraft, where whole air samples were taken during low approaches to find potential sources of methane and ethane emissions. Analysis of these samples using gas chromatography revealed a noticeable increase in methane and ethane concentrations over Long Beach Airport, an area surrounded by numerous plugged oil and gas wells extracting crude oil and natural gas. In this study, we observe that methane and ethane concentrations were lower in the summer and higher in the winter, which can be primarily attributed to seasonal variations in the Atmospheric Boundary Layer height. Our results show that in both summer and winter campaigns, the ratio of these two gases over the airport was approximately 0.03, indicating that for every 100 methane molecules, there are 3 ethane molecules. This work identifies methane and ethane hotspots and provides a critical analysis on potential fugitive emission sources in the Long Beach area. These results emphasize a need to perform in depth analyses on potential point sources of greenhouse gas emissions in the Long Beach area. Katherine Skeen Investigating Elevated Levels of Toluene during Winter in the Imperial Valley Katherine Skeen, University of North Carolina at Charlotte The Imperial County in Southern California experiences pollutants that do not meet the National Ambient Air Quality Standards, and as a result, residents are suffering from adverse health effects. Volatile organic compounds (VOCs) are compounds with a high vapor pressure at room temperature. They are readily emitted into the atmosphere and form ground level ozone. Toluene is a VOC and exposure poses significant health risks, including neurological and respiratory effects. This study aims to use airborne data to investigate areas with high toluene concentrations and investigate potential source. Flights over the Imperial Valley were conducted in the B200 King Air. Whole air canisters were used to collect ambient air samples from outside the plane. These Whole Air Canisters were put through the UCI Rowland Blake Lab’s gas chromatograph mass spectrometer, which identifies different gasses and quantifies their concentrations. Elevated values of toluene were found in the winter as compared to the summer in the Imperial Valley, with the town of Brawley having the most elevated amounts in the air. Excel and QGIS were utilized to analyze data trends. Additionally, a backward trajectory calculated using the NOAA HYSPLIT model revealed the general air flow on days exhibiting high toluene concentrations. Here we suggest Long Beach may be a source of enhanced toluene levels in Brawley. Both areas exhibited enhanced levels of toluene with slightly lower concentrations observed in Brawley. We additionally observed other VOCs commonly emitted in urban areas, and saw a similar decrease in gasses from Long Beach to Brawley. This trend may indicate transport of toluene from Long Beach to Brawley. Further research could be done to investigate the potential for other regions that may contribute to high toluene concentrations in Brawley. My study contributes valuable insights to the poor air quality in the Imperial Valley, providing a foundation for future studies on how residents are specifically being affected. Ella Erskine Characterizing Volatile Organic Compound (VOC) Emissions from Surface Expressions of the Salton Sea Geothermal System (SSGS) Ella Erskine, Tufts University At the southeastern end of the Salton Sea, surface expressions of an active geothermal system are emitting an assemblage of potentially toxic and tropospheric ozone-forming gasses. Gas measurements were taken from ~1 to 8 ft tall mud cones, called gryphons, in the Davis-Schrimpf seep field (~50,000 ft2). The gaseous compounds emitted from the gryphons were collected using whole air sampling canisters. The canisters were then sent to the Rowland-Blake laboratory for analysis using gas chromatography techniques. Samples from June of 2022, 2023, and 2024 were utilized for a time-series analysis of VOC distribution. Originally, an emission makeup similar to petroleum was expected, as it has previously been found in some of the seeps. It is thought that hydrothermal fluid can rapidly mature organic matter into hydrothermal petroleum, so it is logical that the emission makeup could be similar. However, unexpectedly high levels of the VOC benzene were recorded, unlike concentrations generally observed in crude oil emissions. This may indicate a difference between the two sources in regard to their formation process or parent material composition. A possible cause of the elevated benzene could be its relatively high aqueous solubility compared to other hydrocarbons, which could allow it to be more readily incorporated into the hydrothermal fluid. Since the gryphons attract almost daily visitors, it is important to quantify their human health effects. Benzene harms the bone marrow, which can result in anemia. It is also a carcinogen. Additionally, benzene can react with the OH radical to form ozone, an additional health hazard. Future studies should revisit the Davis-Schrimpf field to continue the time series analysis and collect samples of the water seeps. Additionally, drone and ground studies should be conducted in the geothermal power plant adjacent to the gryphons to determine if benzene is being emitted from drilling activities. Amelia Brown Airborne and Ground-Based Analysis of Los Angeles County Landfill Gas Emissions Amelia Brown, Hamilton College California has the highest number of landfills of any individual US state. These landfills are concentrated in densely populated areas of California, especially within the Los Angeles metropolitan area. Landfills produce three main byproducts: heat, leachate, and landfill gas (LFG). LFG is primarily composed of methane (CH₄) and carbon dioxide (CO₂), with small concentrations of volatile organic compounds (VOCs) and other trace gases. The CH4 and CO2 components of LFG are well documented, but the VOCs and trace gases in LFG remain underexplored. This study investigates the emission of trace gases from four landfills in Los Angeles County, with a particular focus on substances known to have high Ozone Depletion Potentials (ODPs) and Global Warming Potentials (GWPs). The four landfills sampled were Chiquita Canyon Landfill, Lopez Canyon Landfill, Sunshine Canyon Landfill, and Toyon Canyon Landfill. Airborne samples were taken above the four landfills and ground samples were taken at Lopez Canyon as this was the only site accessible by our research team. The substances of interest were chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and halons. Airborne CH4 and CO2 measurements over the four landfills were obtained using the Picarro instrument onboard NASA’s B-200 aircraft. Ground samples were collected using whole air sampling canisters and were analyzed to determine the concentrations of these gases. The analytical approach for the ground samples combined Gas Chromatography-Mass Spectrometry (GCMS) with Flame Ionization Detection (FID) and Mass Selective Detection (MSD), providing a comprehensive profile of the emitted compounds. Findings reveal elevated levels of substances with high ODP and GWP, which were banned under the Montreal Protocol of 1987 and its subsequent amendments due to their contributions to stratospheric ozone depletion and climate change. These results underscore the importance of monitoring and mitigating landfill gas emissions, particularly for those containing potent greenhouse gases and ozone-depleting substances.

Gerrit Hoving Predicting Ammonia Plume Presence at Feedlots in the San Joaquin Valley from VSWIR Spectroscopy of the Land Surface Gerrit Hoving, Carleton College Industrial-scale livestock farms, or Concentrated Animal Feeding Operations (CAFOs), are a major source of air pollutants including ammonia, methane, and hydrogen sulfide. Ammonia in particular is a major contributor to rural air pollution that is released from the breakdown of livestock effluent. Mitigating regional air pollution through improved waste management practices is only possible if emissions can be accurately monitored. However, ammonia is challenging to measure directly due to its short atmospheric lifetime and lack of VSWIR spectral signature. Here we investigate the potential for spectroscopic imaging of the CAFO land surface to predict the presence of detectable ammonia emissions. Data from the Hyperspectral Thermal Emission Spectrometer (HyTES) instrument were found to clearly identify plumes of ammonia emitted by specific feedlots. Plume presence or absence was then tied to pixel-level reflectance spectra from the Earth Surface Mineral Dust Source (EMIT) instrument. Random forest classification models were found to predict ammonia plume presence/absence from VSWIR reflectance alone with an accuracy in the range of 70% to 80%. Our conclusions are limited by the limited number of feedlots overflown by HyTES (n=96), the time gap between HyTES and EMIT data, and potential difficulty in comparing feedlots in different regions. While only tested over a modest area, our results suggest that ammonia plume presence/absence may be predictable on the basis of surface features identifiable from VSWIR reflectance alone. Further investigation could focus on more comprehensive model validation, including characterization of the land surface processes and spectral signatures associated with feedlot surfaces with and without observable ammonia plumes. If generalizable, these results suggest that EMIT data may in some circumstances be used to predict the presence of ammonia emission plumes at feedlots in other areas, potentially enabling broader accounting of feedlot ammonia emissions. Benjamin Marshburn Burn to Bloom: Assessing the Impact of Coastal Wildfires on Phytoplankton Dynamics in California Benjamin Marshburn, California Polytechnic State University- San Luis Obispo California is experiencing rising temperatures as well as increased frequency and length of drought conditions due to anthropogenic climate change. Wildfires are an intrinsic component of California and its Mediterranean ecosystems. However, this change in natural wildfire behavior increases the risk to ecosystems including soil erosion, poor plant regrowth, and ash/nutrient runoff that leads to the ocean. Previous work has attributed phytoplankton blooms in the coastal ocean to runoff from wildfires. This study aims to quantify the extent to which the concentration of chlorophyll-a, an indicator of phytoplankton abundance, can be predicted by wildfire parameters in coastal California and to evaluate which parameters are the most important predictors. Due to climatic variation in California we split the coast into three regions, northern, central and southern, and analyzed three fires from each area. For each fire, the stream length connecting the most severely burned area and the ocean was derived from analysis of a digital elevation model acquired by the Shuttle Radar Topography Mission. Additionally, differenced Normalized Burn Ratio (dNBR) was used to analyze burn severity for each fire. The change in chlorophyll-a levels before and after each fire from the impacted coastal area were evaluated using the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. The Random Forest Regression machine learning model did not strongly predict the difference in chlorophyll-a from the fire parameters. However, our moderate R2 value (0.36) shows promising avenues for future work, including investigating post-fire chlorophyll-a after the first significant rain event, as well as the impact of wind-blown ash on coastal chlorophyll-a concentrations. Hannah Samuelson Species-specific Impact on Maximum Fire Temperature in Prescribed Burns at Sedgwick Reserve Hannah Samuelson, University of St. Thomas Fuel load plays a key role in determining severity (change in biomass), intensity (temperature), and frequency (length in time) of wildfires and prescribed fires. Fuel loads can vary in fuel conditions, like moisture content, amount, and flammability of the fuel, and are affected by species type and climatic conditions. Moreover, the difference in the chemical composition of plant species can affect its flammability. Anecdotal evidence from firefighters claim that Purple Sage burns hotter than other shrubs. Here we focus on two shrub species and two tree species that are broadly representative of California foothills; Blue Oak (Quercus douglasii), Coast Live Oak (Quercus agrifolia), Purple Sage (Salvia leucophylla), and California Sagebrush (Artemisia californica), and aim to understand species-specific proclivity to burn with higher or lower severity and intensity. In fall of 2023, a prescribed fire was conducted at Sedgwick Reserve in Santa Barbara County, CA. Field data collection included maximum temperature point measurements with metal pyrometers, the change in 3D vegetation structure using UAV LiDAR, and orthomosaic images for species identification. Radial buffers were created around the locations of the metal pyrometers and used to evaluate the spatial distribution of species, which were verified through field-observed species identification. The relationship between dominant overstory species, change in biomass, and maximum fire temperature was investigated. Preliminary results suggest that Purple Sage produced the highest maximum fire temperatures. Additionally, preliminary results showed both tree species, Blue Oak and Coast Live Oak, exhibit similar biomass change at low maximum fire temperatures. This investigation confirmed the firefighters’ anecdotal evidence on the relationship between species and their wildfire dynamics. The results have the potential to refine fire spread models and ultimately land management practices, improving the protection of humans and infrastructure while preventing habitat destruction from wildfires. Angelina Harris Quantifying the Influence of Soil Type, Slope, and Aspect on Live Fuel Load in Sedgwick Reserve Angelina Harris, William & Mary The severity and increasing frequency of California wildfires requires investigation of factors that characterize pre-fire landscapes to improve approaches to wildland management and predict the spread of wildfire. Quantifying the relationship between soil type and fuel load could improve existing efforts to map both overall quantity and composition of live fuel for fire spread models which may assist in preventative wildfire measures and potentially active firefighting work. The southwest corner of Sedgwick Reserve, Santa Barbara County, CA hosts two dominant soil types that broadly represent soil variability in the area. The more northerly soil unit is a Chamise shaly loam, and the more southerly soil unit is a Shedd silty clay loam. The Chamise series has a mixed texture, abundant in clay with a significant amount of rock fragments (> 35%) composing its texture while the Shedd series has a fine texture dominated by silt-sized particles. Topography, specifically slope and aspect, plays a significant role in formation and characteristics of soil due to influence on erosion and deposition and sun exposure, respectively. This research aims to explore the relationship between soil type and topography and quantify their influence on live fuel using a Canopy Height Model (CHM) derived from airborne LiDAR collected on 11/04/2020 with a point density of 10.19 pts/m2. The LiDAR-based CHM was filtered to separate trees (> 2 m) and shrubs (.07 – 2 m). A Random Forest Regressor was used to investigate the relationship between soil type, slope, and aspect to identify which variable is the best predictor of canopy height. Preliminary results suggested that soil type and aspect were the most important variables to determine canopy height (variable importance of .50 and .41, respectively). Further studies investigating quantity and composition of live fuel load focusing on additional soil units within Sedgwick Reserve are encouraged. Emily Rogers From Canopy to Chemistry: Exploring the Relationship Between Vegetation Phenology and Isoprene Emission Emily Rogers, Bellarmine University Isoprene (2-methyl-1,3-butadiene) represents the most abundant non-methane biogenic volatile organic compound in the troposphere, with annual emissions almost equal to those of methane. Depending on the chemical environment, this effective thermoregulator and reactive oxygen species scavenger participates in photochemical reactions to produce climate pollutants and toxins such as ozone and secondary organic aerosols. Previous studies have revealed strong connections between isoprene emission and photosynthesis as its precursors are formed during the Calvin Cycle. This raises questions as to whether the periodic biological events of plants, collectively known as vegetation phenology, influences tropospheric isoprene quantities. In this study, we investigate the influence of vegetation phenology on isoprene emission in Southern California by comparing photosynthetic activity and the spatial distribution of the isoprene oxidation product, formaldehyde, for regions dominated by plants of two different physiologies: high altitude woodlands and coastal shrublands. We interrogate the annual phenology of these regions using high resolution solar-induced chlorophyll fluorescence (SIF) estimates from the Orbiting Carbon Observatory-2 (OCO-2) satellite, and formaldehyde vertical column measurements from the recently activated Tropospheric Emissions: Monitoring of Pollution (TEMPO) geostationary satellite. We explore the seasonal trends in both formaldehyde formation and SIF as well as their bivariate relationship. Preliminary results indicate both heightened formaldehyde emission and heightened SIF during summer months relative to winter months, with a comparatively stronger correlation between the two metrics during the fall. Our findings will provide insight toward the response of plants to variations in their environment which directly influence chemical systems in the air. Whereas VOCs hold a great potential for environmental and anthropological harm if emitted in excess, it is crucial to understand the factors involved in their formation. As such, we hope that our findings provide information relevant to the development of air pollution mitigation strategies. Sydney Kent Keeping it Fresh(water): Understanding the Influence of Surface Mineralogy on Groundwater Quality within Volcanic Aquifer Systems Sydney Kent, Miami University Geology plays a key role in determining the chemical profile of groundwater through weathering and erosion, leading to minerals entering the groundwater. The Columbia Plateau, a geologic region that resides within the Pacific Northwest volcanic aquifer system, is known to have water management issues due to groundwater extraction for agriculture. Decreases in groundwater levels can lead to higher concentrations of rock-originated minerals, so the relationship between basaltic geology and well water quality is particularly important in these systems. This research aims to assess the extent in which the basaltic surface mineralogy of the Columbia Plateau impacts predetermined health benchmarks pertaining to trace elements, radionuclides, and nutrients. NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) instrument, a spaceborne imaging spectrometer on the International Space Station, was used to map surface minerals within and among distinct regions of the Columbia Plateau. Some basalt aquifers have uranium that decays to radon-222, a mineral that can be toxic when consumed, as well as lithium, which is commonly found during volcanic eruptions. Preliminary findings showed that where basalt and its secondary minerals were identified with EMIT, chlorite and calcite, well data also indicated raised levels of lithium and radon-222. The relationship between EMIT mineral maps and water quality data indicated that EMIT can potentially be used to identify basalt aquifer systems that may be at risk of poor water quality. Results from this study can be used to enact more personalized water purification methods in areas with water quality issues and individuals with private wells can be more informed about the hazards present in their water.

Maya Niyogi A Comparative Analysis of Tropospheric NO2: Evaluating TEMPO Satellite Data Against Airborne Measurements Maya Niyogi, Johns Hopkins University Nitrogen dioxide (NO2) plays a major role in atmospheric chemical reactions; the inorganic compound both contributes to tropospheric ozone production and reacts with volatile organic compounds to create health-hazardous particulate matter. The presence of NO2 in the atmosphere is largely due to anthropogenic activity, making NO2 at the forefront of policy decisions and scientific monitoring. The Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite launched in 2023 with the goal of monitoring pollution across North America. The publicly-accessible data became available for use in May 2024, however parts of the data remain unvalidated and in beta, creating a need for an in situ validation of its data products. Here we analyze TEMPO’s tropospheric NO2 measurements and compare them to aloft NO2 measurements collected during the NASA Student Airborne Research Project (SARP) 2024 airborne campaign. Six of the campaign flights recording NO2 performed a vertical spiral, providing vertical column data that was adjusted to ambient conditions for comparison against the corresponding TEMPO values. Statistical analyses indicate we have reasonable evidence to conclude that TEMPO satellite data and the flight-collected data record similar values. This research fills a critical knowledge gap through the utilization of aloft NO2 measurements to validate NASA’s newly-launched TEMPO satellite. It is expected that future users of TEMPO data can apply these results to better inform project creation and research. Benjamin Wells Investigating the Atmospheric Burden of Black Carbon Over the Past Decade in the Los Angeles Basin Benjamin Wells, San Diego State University Black Carbon is a primary aerosol emitted directly into the atmosphere as a result of biomass burning and incomplete combustion of fossil fuels. During the pre-industrial revolution, the main source of black carbon was natural sources whereas currently, the main source is anthropogenic activities. When black carbon is released into the atmosphere, it is a dominant absorber of solar radiation and leads to a significant warming effect on Earth’s climate. In addition to its harmful effects associated with climate change, ambient black carbon inhalation is correlated with adverse health effects such as respiratory and cardiovascular disease, cancer, and premature mortality. In this study, we analyze aloft black carbon measurements in 2016 and 2024 acquired on NASA SARP research flights and compare these concentrations to black carbon measurements taken during the 2010 CalNex field campaign. Both field campaigns flew similar flight paths over the Los Angeles basin allowing us to conduct a critical comparative analysis on vertical and spatial profiles of the atmospheric burden of black carbon over the past 14 years. During the CalNEX study, mass concentrations of black carbon ranged from 0.02 μg/m3 to 0.531 μg/m3, meanwhile 2024 SARP measurements demonstrate concentrations as elevated as 7.83 μg/m3 within the same region. Moreover, similar flight paths conducted during SARP 2024 and 2016 allow for further analysis of aloft black carbon concentrations over a period of time. The results of this study examines and analyzes the changing spatial and temporal characteristics of black carbon throughout the years, leading to an increase of adverse effects on both the climate and public health. Devin Keith Tracking Methane and Aerosols in relation to Health Effects in the San Joaquin Valley Devin Keith, Mount Holyoke College The San Joaquin Valley (SJV) is located in central California and is one of the most productive agricultural regions in the country for dairy, nuts, and berries, producing more than half of California’s $42 billion output. Due to the SJV’s close proximity to the Sierra Nevada Mountain Range to the East and predominantly Easterly winds, air pollution often accumulates because it is trapped by the geography. Significant chemical constituents of trapped particulate matter are ammonium (NH4), chloride (Cl), sulfate (SO4), nitrate (NO3), black carbon, and organic carbon. The particle size measured in this study is less than 1 micron in diameter, and due to their size, can easily penetrate the respiratory tract leading to adverse health effects such as: asthma, chronic obstructive pulmonary disease, and cardiovascular disease. We employ airborne data collected during the SARP 2024 mission onboard NASA’s P-3 research plane to observe spatial and temporal trends of NH4, Cl, SO4, NO3, and black carbon. Further, we analyze measurements from SARP 2016 flights and compare the atmospheric burden of pollution in the SJV across time. To investigate observations in the context of the public health impacts, we utilize data collected by the California Office of Environmental Health Hazards Assessment and find asthma and cardiovascular disease rates are higher in the SJV hotspots identified here. Per capita health impacts are greater than other California regions such as Los Angeles and San Francisco. The SJV exhibits higher rates of poverty than other communities, which may reveal an environmental justice issue that is difficult to explicitly quantify especially where measurements are sparse. Lily Lyons Investigating the Effects of Aerosols on Photosynthesis Using Satellite Imaging Lily Lyons, Brandeis University Aerosols in the atmosphere can affect the way sunlight travels to the ground by absorbing or scattering light. Sunlight is a critical component in plant photosynthesis, and the way light scatters affects productivity for vegetation and plant growth. When plants absorb sunlight, the chlorophyll in their leaves releases the excess energy as infrared light, which can be measured from space via satellite. To better understand how aerosol loading in the atmosphere affects plant photosynthesis, this study examines locations in Yosemite, Sequoia, Garrett, and Talladega national forests, and compares aerosol optical depth (AOD), normalized difference vegetation index (NDVI), and solar induced fluorescence (SIF) in these areas. Yosemite and Sequoia act as proxies for the old growth sequoia grove ecosystems, and Talladega and Garrett act as proxies for the Appalachian mixed mesophytic forest ecosystem. Our results show that within 2015-2020 during July, SIF and NDVI levels are significantly greater in mixed mesophytic forests than in sequoia groves. Using linear regression plots, we determined the correlation between SIF, NDVI and AOD to be weak in the given locations. Greater SIF in mixed mesophytic forests could suggest that the presence of a prominent and biodiverse understory is positive for the overall primary productivity of an ecosystem. This study is a good starting point for analyzing diverse ecosystems using SIF, NDVI and satellite data as proxies for photosynthesis, and broadening the scope of biomes examined for their SIF. Furthermore, it highlights the need for further investigation of aerosol impact on the trajectory and amount of sunlight that reaches certain plants. Ryleigh Czajkowski Validating the Performance of CMAQ in Simulating the Vertical Distribution of Trace Gases Ryleigh Czajkowski, South Dakota School of Mines and Technology Air quality modeling simulates atmospheric processes and air pollutant transport to better understand gas-and particle-phase interactions in the atmosphere. The Environmental Protection Agency’s (EPA) Community Multiscale Air Quality (CMAQ) model couples meteorological, emission, and chemical transport predictions to simulate air pollution from local to hemispheric scales. CMAQ provides scientists and regulatory agencies with important assistance in air quality management, policy enactment, atmospheric research, and creating public health advisories. Recently, a new update to CMAQ (v5.4) was released, utilizing new chemistry mechanisms and incorporating a new atmospheric chemistry model. This study evaluates the performance of the latest model update by analyzing multiple time series of vertical distributions of formaldehyde (CH2O) and methane (CH4) in the Los Angeles Basin and Central Valley regions of California. It compares data from aloft measurements taken during NASA SARP 2017 flights with model predictions to evaluate accuracy. Our study analyzes CMAQ’s capabilities in capturing the vertical dispersion of CH2O and CH4 in different regions, offering insights into the effectiveness of CMAQ for air quality management and the analysis of trace and greenhouse gas dynamics. Using NASA airborne data, this research utilizes a diversified data set to validate the model, providing a more comprehensive evaluation of its capabilities, and thus providing valuable insight into future developments of CMAQ. Alison Thieberg Estimating Aerosol Optical Properties Using Mie Theory and Analyzing Their Impact on Radiative Forcing in California Alison Thieberg, Emory University Anthropogenic aerosols, unlike greenhouse gasses, provide a net cooling effect to the Earth’s surface. Particles suspended in the atmosphere have the ability to scatter incoming solar radiation, preventing that radiation from heating up the surface. These aerosols like black carbon, ammonium nitrate, ammonium sulfate, and organics are byproducts of both natural and anthropogenic activities. Measuring radiative forcing as a result of these aerosols over time can provide insight on how anthropogenic industries are altering our Earth’s temperature. This study analyzes the changes in radiative forcing from aerosols in central and southern California using data collected from NASA SARP flights from 2016-2024. Aerosol size, composition, and single scattering albedo were used to estimate the aerosol characteristics and to calculate the aerosols’ radiative forcing efficiency. Our results show that aerosols are found to have less of a cooling effect over time when looking at the change in radiative forcing in California from 2016 to 2024. When narrowing in on specific geographic regions, we observe the same trends in the Central Valley with the area becoming warmer as a result of aerosols. However, more southern regions like Los Angeles and the Inland Empire have become cooler from aerosols during this time period. The overall decrease in the cooling effect of California’s aerosols could indicate that the average size of particulates is changing or that the aerosol composition could be shifting to a greater concentration of absorbing aerosols rather than scattering aerosols. This study shows how aerosols influence radiative forcing and their subsequent impacts across regions in California from multiple years. Click here watch the Terrestrial Ecology Group presentations.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Student Airborne Research Program (SARP) 2024 West Coast cohort poses in front of the natural sciences building at UC Irvine, during their final presentations on August 12, 2024. NASA Ames/Milan Loiacono On August 12-13, 24 students from the West Coast cohort of NASA’s Student Airborne Research Program (SARP) gathered at University of California, Irvine (UCI) to present their final research to a room of mentors, professors, family, and NASA personnel. SARP is an eight-week summer internship for undergraduate students, hosted in two cohorts: SARP West operates out of Ontario Airport and UCI in California, while SARP East operates out of Wallops Flight Facility and Christopher Newport University in Virginia. After research introductions from faculty, instrument scientists, and staff, students are assigned one of four research categories: for SARP West, these categories are aerosols, terrestrial ecology, whole air sampling (WAS), or oceans. Each group is led by a dedicated researcher who is a specialist in that field, along with a graduate student mentor. Over the course of the summer, each intern develops their own research project as they conduct field work, collect data, and fly onboard either the P-3 or B200 NASA flying laboratories. “You really see them become scientists in their own right,” said Stephanie Olaya, Program Manager for SARP East and West. “A lot of these projects are PhD level: they are researching and making novel discoveries for the field. They don’t even realize the magnitude of the things they’ve accomplished until the end of the program.” You really see them become scientists in their own right. A lot of these projects are PhD level: they are researching and making novel discoveries for the field. Stephanie olaya SARP Program Manager Research is not the only focus of the program, however. Faculty and mentors alike commented on the confidence they watched grow in the cohort over the two month internship, and the sense of camaraderie with their peers. Olaya says building a sense of community is a primary goal of the program, which encourages close friendships through communal living, regular group dinners, and weekend trips, in addition to the hours of team fieldwork, data collection, and laboratory analysis. The final presentations are another critical facet of the program, as it teaches students how to communicate scientific research and results to a non-scientific audience. “We want to impress on these students that science is not just for scientists,” Olaya said. “Science is for everyone.” The event finished with closing remarks by Barry Lefer, Tropospheric Composition Program Manager at NASA Headquarters. “I want to welcome you to the SARP family,” Lefer said, “and to the NASA family.” To watch videos of these student’s presentations and/or read their research abstracts, please follow the links below. 2023 SARP West Research Presentation Topics: Oceans Group Watch the Ocean Group Presentations Introduced by Oceans Group PhD student mentor Lori Berberian, University Of California, Los Angeles Leveraging high resolution PlanetScope imagery to quantify oil slick spatiotemporal variability in the Santa Barbara Channel Emory Gaddis, Colgate University Investigating airborne LiDAR retrievals of an emergent South African macroalgae Rachel Emery, The University of Oklahoma Vertical structure of the aquatic light field based on half a century of oceanographic records from the Southern California current Brayden Lipscomb, West Virginia University Comparing SWOT and PACE satellite observations to assess modification of phytoplankton biomass and assemblage by North Atlantic ocean eddies Dominic Bentley, Pennsylvania State University Assessing EMIT observations of harmful algae in the Salton Sea Abigail Heiser, University of Wisconsin- Madison Reassessing multidecadal trends in water clarity for the Central and Southern California current system Emma Iacono, North Carolina State University Atmospheric Aerosols Group Watch the Atmospheric Aerosols Group Presentations Introduced by Atmospheric Aerosols PhD student mentor Madison Landi, University of California, Irvine A comparative analysis of tropospheric NO2: Evaluating TEMPO satellite data against airborne measurements Maya Niyogi, Johns Hopkins University Investigating the atmospheric burden of black carbon over the past decade in the Los Angeles Basin Benjamin Wells, San Diego State University Tracking methane and aerosols in relation to health effects in the San Joaquin Valley Devin Keith, Mount Holyoke College Investigating the effects of aerosols on photosynthesis using satellite imaging Lily Lyons, Brandeis University Validating the performance of CMAQ in simulating the vertical distribution of trace gases Ryleigh Czajkowski, South Dakota School of Mines and Technology Estimating aerosol optical properties using Mie Theory and analyzing their impact on radiative forcing in California Alison Thieberg, Emory University Whole Air Sampling (WAS) Group Watch the Whole Air Sampling (WAS) Group Presentations Introduced by WAS PhD student mentor Katherine Paredero, Georgia Institute of Technology Urban planning initiative: Investigation of isoprene emissions by tree species in the LA Basin Mikaela Vaughn, Virginia Commonwealth University VOC composition and ozone formation potential observed over Long Beach, California Joshua Lozano, Sonoma State University Investigating enhanced methane and ethane emissions over the Long Beach Airport Sean Breslin, University of Delaware Investigating elevated levels of toluene during winter in the Imperial Valley Katherine Skeen, University of North Carolina at Charlotte Characterizing volatile organic compound (VOC) emissions from surface expressions of the Salton Sea Geothermal System (SSGS) Ella Erskine, Tufts University Airborne and ground-based analysis of Los Angeles County landfill gas emissions Amelia Brown, Hamilton College Terrestrial Ecology Group Watch the Terrestrial Ecology Group Presentations Introduced by Terrestrial Ecology PhD student mentor Megan Ward-Baranyay, San Diego State University Predicting ammonia plume presence at feedlots in the San Joaquin Valley from VSWIR spectroscopy of the land surface Gerrit Hoving, Carleton College Burn to bloom: Assessing the impact of coastal wildfires on phytoplankton dynamics in California Benjamin Marshburn, California Polytechnic State University- San Luis Obispo Species-specific impact on maximum fire temperature in prescribed burns at Sedgwick Reserve Hannah Samuelson, University of St. Thomas Quantifying the influence of soil type, slope, and aspect on live fuel load in Sedgwick Reserve Angelina Harris, William & Mary From canopy to chemistry: Exploring the relationship between vegetation phenology and isoprene emission Emily Rogers, Bellarmine University Keeping it fresh(water): Understanding the influence of surface mineralogy on groundwater quality within volcanic aquifer systems Sydney Kent, Miami University About the AuthorMilan LoiaconoScience Communication SpecialistMilan Loiacono is a science communication specialist for the Earth Science Division at NASA Ames Research Center.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Starfish Space has been awarded SBIR Phase III funding for a mission to inspect defunct satellites to increase opportunities to mitigate space debris. An artist’s concept image shows the company’s Otter spacecraft, which is capable of inspecting and deorbiting defunct spacecraft, in orbit.Starfish Space NASA is advancing an innovative approach to enabling commercial inspection of defunct, or inoperable, satellites in low Earth orbit, a precursor to capturing and repairing or removing the satellites. The agency has awarded Starfish Space of Seattle, Washington, a Phase III Small Business Innovation Research (SBIR) contract to complete the Small Spacecraft Propulsion and Inspection Capability (SSPICY) mission. The award follows a Phase III study, which funded four U.S. small businesses including Starfish to develop mission concepts. Starfish Space will receive $15 million over three years to execute the mission. The ability to inspect defunct spacecraft and identify opportunities for repair or deorbiting is critical to maintaining a safe orbital environment for spacecraft and humans. Orbital debris mitigation is a key component of NASA’s Space Sustainability Strategy. “The SSPICY mission is designed to mature technologies needed for U.S. commercial capabilities for satellite servicing and logistics or disposal,” said Bo Naasz, senior technical lead for in-space servicing, manufacturing, and assembly in NASA’s Space Technology Mission Directorate. “In-space inspection helps us characterize the physical state of a satellite, gather data on what may leave spacecraft stranded, and improve our understanding of fragmentations and collisions, a difficult but critical factor in a sustainable space operating environment.” The Starfish-led mission uses the company’s Otter spacecraft, a small satellite about the size of an oven, which is designed to inspect, dock with, and service or deorbit other satellites. Otter’s electric propulsion system will not only help it efficiently travel to multiple satellites, but the SSPICY demonstration also will mature the spacecraft’s ability to perform inspections using electric propulsion, an important enabling technology not typically used for rendezvous and proximity operations. During the SSPICY mission, Otter will visit and inspect multiple U.S. owned defunct satellites that have agreed to be visited and inspected – a delicate and challenging task, as satellites move quickly and are kept far apart from each other for safety. Otter will approach within hundreds of meters of each satellite to conduct inspections during mission operations. During the inspection, Otter will gather key information about each of the debris objects including their spin rate, spin axes, and current conditions of the objects’ surface materials. The SSPICY mission is the first commercial space debris inspection funded by NASA and supports the agency’s efforts to extend the life of satellites while reducing space debris. Satellites that are no longer in use can break apart or collide with one another, creating debris clouds that pose risk to human spaceflight, science and robotic missions in Earth’s orbit, and missions to other planets in the solar system. Data from inspections like those planned during the SSPICY demonstration will play a critical role in understanding the nature of defunct satellites and advancing solutions for reuse or disposal. “We are excited to expand our partnership with NASA, building on our shared commitment to advancing in-space manufacturing and assembly capabilities,” said Trevor Bennett, co-founder of Starfish Space. “It’s an honor for Starfish to lead the first commercial debris inspection mission funded by NASA. We look forward to collaborating on this and future satellite servicing missions to enable a new paradigm for humanity in space.” The Otter spacecraft is expected to launch in late 2026 and will begin performing inspections in 2027. The SSPICY demonstration is funded and managed by NASA’s Small Spacecraft Technology program based at NASA’s Ames Research Center in California’s Silicon Valley. The award is enabled by NASA’s SBIR program, which is open to U.S. small businesses to develop an innovation or technology. These programs are part of NASA’s Space Technology Mission Directorate.

Dave Gwaltney, second from left, technical assistant, specialty system and Commercial Crew Program representative at NASA’s Marshall Space Flight Center, gives introductions during the Crew-9 flag-raising ceremony Sept. 19 outside the Huntsville Operations Support Center. He is joined by, from left, Brady Doepke, Thomas “Reid” Lawrence, and Nicole Pelfrey, manager of the Payload and Mission Operations Division. NASA/Krisdon Manecke Crew-9 will be the first human spaceflight mission to launch from Space Launch Complex-40 at Cape Canaveral Space Force Station. This is the ninth crew rotation mission with SpaceX to the orbiting laboratory under NASA’s Commercial Crew Program (CCP). The crew will spend approximately five months at the station, conducting more than 200 science and research demonstrations before returning in February 2025. Once aboard the space station, Hague and Gorbunov will become members of the Expedition 72 crew and perform research, technology demonstrations, and maintenance activities. The pair will join NASA astronauts Don Petitt, Butch Wilmore, Suni Williams, as well as Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. Wilmore and Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025. Thomas “Reid” Lawrence raises the Crew-9 mission flag as Doepke looks on during the flag-raising ceremony to honor NASA’s Space X Crew-9 Mission to the International Space Station. NASA/Serena Whitfield The flag raising has been a tradition for missions supported at Marshall’s Huntsville Operations Support Center (HOSC), as well as a tradition within the CCP to celebrate the successful conclusion of NASA’s Agency Flight Readiness Review prior to launch. The HOSC provides engineering and mission operations support for the space station, the CCP, and Artemis missions, as well as science and technology demonstration missions. The Payload Operations Integration Center within HOSC operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day. The CCP support team at Marshall provides crucial programmatic, engineering, and safety and mission assurance expertise for launch vehicles, spacecraft propulsion, and integrated vehicle performance. Marshall’s role within the CCP is to support certification that the spacecraft and launch vehicle are ready for launch. The support team performs engineering expertise, particularly for propulsion, as well as program management, safety and mission assurance, and spacecraft support. The Crew-9 mission flag is raised during the ceremony outside the Huntsville Operations Support Center.NASA/Serena Whitfield The flag-raising ceremony was a joint effort between the Payload and Mission Operations Division (PMOD) and CCP team.

(NASA/Jennifer Deermer) › Back to Top Take 5 with Shannon Segovia By Wayne Smith Talk with Shannon Segovia for any length of time and you’ll quickly discover the care and enthusiasm she has for her position as director of the Office of Communications at NASA’s Marshall Space Flight Center. And that care and enthusiasm extends to those she works with across the center to share news about Marshall missions and team members. In her role, Segovia oversees a team responsible for media relations and public affairs, digital and social media, stakeholder relations and engagement, internal and employee communications, and executive communications for the center. Shannon Segovia, director of the Office of Communications at NASA’s Marshall Space Flight Center, in front of Artemis I before its launch.Photo courtesy of Shannon Segovia “We manage these activities for the entire center of about 7,000 people, so it is a definitely a very busy job!” said Segovia, a native of Athens, Alabama, who was named as permanent communications director this summer after more than 12 years at Marshall. She was the deputy director of communications starting in June 2023 after working as Marshall’s news chief and public affairs team lead starting in 2019. From 2012 to 2019, Segovia was a public affairs officer at the center. Prior to joining NASA, she was the communications manager for the Tennessee Valley Authority’s Sequoyah Nuclear Plant near Chattanooga, Tennessee. At Marshall, she said it’s the people who continue to be her biggest motivators. “As a public servant, I want the people I serve – the people who follow our channels, listen to the news stories we create, and attend our events – to know why NASA’s missions are important and critical to the world we live in,” Segovia said. “I am so fortunate to have such a brilliant team, and they motivate me daily with their hard work.” “I’m also motivated by my husband and family because I want to make them proud. I want my nieces and nephews to have a bright future, and I truly believe the work we are doing at NASA will help them do that.” Question: What excites you most about the future of human space exploration, or your NASA work, and your team’s role it? Segovia: NASA’s missions depend on public and stakeholder support, and that is what our office does – ensures people know what we are doing at NASA and specifically at Marshall, why it is important, and how our missions are benefiting humanity. From social media posts to events like the South Star music festival to interviews with media outlets and stakeholder tours, we use every channel we can to tell others about the work we are doing at Marshall and NASA. Our office touches every organization at the center, and it is so exciting to have a front seat to everything we are doing to get humans back to the Moon and on to Mars. Shannon Segovia, right center, with some of the engineers from Marshall she accompanied during a visit to The Today Show in New York in 2019 for a segment about International Women’s Day. From left, Kathy Byars, Katherine Van Hooser, Lakiesha Hawkins, Segovia, Michelle Tillotson Rudd, and Lisa Watson-Morgan. Photo courtesy of Shannon Segovia Question: What has been the proudest moment of your career and why? Segovia: I helped take a team of 12 Marshall female engineers to The Today Show in 2019 for a segment about International Women’s Day. As a public affairs specialist, one of our job duties is to prepare subject matter experts for interviews, making sure they have messages, talking points, and anything else they need. I have never been more proud to be a woman and to work for Marshall than I was that day, seeing how well these women represented NASA and the extraordinary achievements they have made possible. It also made me even more thankful for the job I have – preparing them to make sure they felt confident and could talk about their work was a wonderful experience. The other moment in my career I will never forget is the Artemis I launch in November 2022. I’ve supported the Space Launch System since I started working at NASA, and seeing that rocket fly was one of the best moments of my career. It was the culmination of so much hard work and sacrifice from so many people and was truly an overwhelming and amazing experience. Question: Who or what inspired you to pursue an education/career that led you to NASA and Marshall? Segovia: My parents have always been my No. 1 fans, encouragers, and supporters. They instilled in me a strong work ethic and the belief I could do anything I wanted to do if I worked hard. They made education a priority for my brothers and I and would do anything to help us succeed. I am so fortunate to have such a wonderful family. My mom always wanted me to do something in the medical field, but a biology course in college changed my mind quickly on that. I wasn’t sure what I wanted to do but had been at school for two years and needed to declare a major. I liked to write and read but didn’t know how to make a career out of that until I went to a journalism class taught by Ms. Bobbie Hurt at the University of North Alabama, and I was hooked. She became my mentor and really taught me how to be a good writer, which has been the foundation for my entire career. I ended up with a double major in journalism and public relations, and it was one of the best decisions I ever made. Question: What advice do you have for employees early in their NASA career or those in new leadership roles? Segovia: Find people to whom you can go to for advice, who have your back, and can help you accomplish your goals. I’ve had some amazing mentors, teammates, and bosses who have not only supported me but pushed me to do things I wasn’t sure I could do and helped me even when I messed up. I would not be here without them, and I think it is so important to have those people in your entire career, but especially when you are new. Ask for help when you need it. Time flies, so enjoy the season and job you are in. You will know when it is time to move on, but being present and learning from where you are will help you succeed. Question: What do you enjoy doing with your time while away from work? Segovia: I love the water – ocean, river, pool, lake – I like being outside and water activities. I love to read and travel, and also to spend time with family and friends. I have three nieces and two nephews, and I like to go to their games and activities. I have a 4-year-old terrier mix named Ted and I enjoy taking him on walks and to the park.

The innovations from this challenge aim to support NASA’s Artemis missions, which will establish long-term human presence on the Moon. Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from The University of California, Santa Barbara won the $1 million grand prize in NASA’s Watts on the Moon Challenge. Their team developed a low-mass, high efficiency cable and featured energy storage batteries on both ends of their power transmission and energy storage system. NASA/GRC/Sara Lowthian-Hanna This two-phase competition has challenged U.S. innovators to develop breakthrough power transmission and energy storage technologies that could enable long-duration Moon missions to advance the nation’s lunar exploration goals. The final phase of the challenge concluded with a technology showcase and winners’ announcement ceremony Sept. 20 at Great Lakes Science Center in Cleveland, Ohio, home of the visitor center for NASA’s Glenn Research Center. “Congratulations to the finalist teams for developing impactful power solutions in support of NASA’s goal to sustain human presence on the Moon,” said Kim Krome-Sieja, acting program manager for Centennial Challenges at NASA’s Marshall Space Flight Center. “These technologies seek to improve our ability to explore and make discoveries in space and could have implications for improving power systems on Earth.” NASA astronaut Stephen Bowen, who flew on three space shuttle missions and served as commander of the SpaceX Crew-6 mission in 2023, engages with one of the Phase 2 finalist teams about their innovative hardware at NASA’s Watts on the Moon Challenge Technology Showcase and Winners’ Event at the Great Lakes Science Center in Cleveland, Ohio, on Sept. 20. Prototypes like the one shown here aim to provide power transmission and energy storage capabilities to the lunar south pole. NASA/Sara Hanna-Lowthian The winning teams are: First prize ($1 million): H.E.L.P.S. (High Efficiency Long-Range Power Solution) of Santa Barbara, California Second prize ($500,000): Orbital Mining Corporation of Golden, Colorado Four teams were invited to refine their hardware and deliver full system prototypes in the final stage of the competition, and three finalist teams completed their technology solutions for demonstration and assessment at Glenn. The technologies were the first power transmission and energy storage prototypes to be tested by NASA in a vacuum chamber mimicking the freezing temperature and absence of pressure found at the permanently shadowed regions of the Lunar South Pole. The simulation required the teams’ power systems to demonstrate operability over six hours of solar daylight and 18 hours of darkness with the user three kilometers (nearly two miles) away from the power source. During this competition stage, judges scored the finalists’ solutions based on a Total Effective System Mass (TESM) calculation, which measures the effectiveness of the system relative to its size and weight – or mass – and the total energy provided by the power source. The highest-performing solution was identified based on having the lowest TESM value – imitating the challenges that space missions face when attempting to reduce mass while meeting the mission’s electrical power needs. Mary Wadel, center right, NASA Glenn Research Center’s Director of Research, Technology, and Partnerships, Bowen, and Great Lakes Science Center President and CEO Kirsten Ellenbogen, right, listen intently while Orbital Mining Corporation team lead Ken Liang explains his team’s approach to the mission scenario behind the Watts on the Moon Challenge. His team’s power transmission and energy storage technology took home the second-place prize in the four-year, $5 million challenge, winning a cash prize of $500,000. NASA/Sara Hanna-Lowthian Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from University of California, Santa Barbara, won the grand prize for their hardware solution, which had the lowest mass and highest efficiency of all competitors. The technology also featured a special cable operating at 800 volts and an innovative use of energy storage batteries on both ends of the transmission system. They also employed a variable radiation shield to switch between conserving heat during cold periods and disposing of excess heat during high power modes. The final 48-hour test proved their system design effectively met the power transmission, energy storage, and thermal challenges in the final phase of competition. Orbital Mining Corporation, a space technology startup, received the second prize for its hardware solution that also successfully completed the 48-hour test with high performance. They employed a high-voltage converter system coupled with a low-mass cable and a lithium-ion battery. “The energy solutions developed by the challenge teams are poised to address NASA’s space technology priorities,” said Amy Kaminski, program executive for Prizes, Challenges, and Crowdsourcing in NASA’s Space Technology Mission Directorate at NASA Headquarters. “These solutions support NASA’s recently ranked civil space shortfalls, including in the top category of surviving and operating through the lunar night.” Watch the finale of NASA’s Watts on the Moon challenge, a $5 million, two-phase competition designed to develop breakthrough power transmission and energy storage technologies. During the technology showcase and winners’ announcement ceremony, NASA experts, media, and members of the public gathered to see the finalist teams’ technologies and hear perspectives from the teams’ participation in the challenge. After the winners were announced, event attendees were also welcome to meet NASA astronaut Stephen Bowen. The Watts on the Moon Challenge is a NASA Centennial Challenge led by Glenn. Marshall manages Centennial Challenges, which are part of the agency’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate. NASA contracted HeroX to support the administration of this challenge. › Back to Top Michoud Continues Work on Evolved Stage of SLS Rocket for Future Artemis Missions Manufacturing equipment that will be used to build components for NASA’s SLS (Space Launch System) rocket for future Artemis missions is being installed at the agency’s Michoud Assembly Facility. The novel tooling will be used to produce the SLS rocket’s advanced exploration upper stage, or EUS, in the factory’s new manufacturing area. The EUS will serve as the upper, or in-space, stage for all Block 1B and Block 2 SLS flights in both crew and cargo configurations. Manufacturing equipment that will be used to build components for NASA’s SLS (Space Launch System) rocket for future Artemis missions is being installed at the agency’s Michoud Assembly Facility. The tooling will be used to produce the SLS rocket’s advanced exploration upper stage, or EUS, in the factory’s new manufacturing area, pictured here.NASA/Evan Deroche In tandem, NASA and Boeing, the SLS lead contractor for the core stage and exploration upper stage, are producing structural test articles and flight hardware structures for the upper stage at Michoud and the agency’s Marshall Space Flight Center. Early manufacturing is already underway at Michoud while preparations for an engine-firing test series for the upper stage are in progress at nearby Stennis Space Center. “The newly modified manufacturing space for the exploration upper stage signifies the start of production for the next evolution of SLS Moon rockets at Michoud,” said Hansel Gill, director at Michoud. “With Orion spacecraft manufacturing and SLS core stage assembly in flow at Michoud for the past several years, standing up a new production line and enhanced capability at Michoud for EUS is a significant achievement and a reason for anticipation and enthusiasm for Michoud and the SLS Program.” Michoud facility technicians Cameron Shiro, foreground, Michael Roberts, and Tien Nguyen, background, install the strain gauge on the forward adapter barrel structural test article for the exploration upper stage of the SLS rocket.NASA/Eric Bordelon The advanced upper stage for SLS is planned to make its first flight with Artemis IV and replaces the single-engine Interim Cryogenic Propulsion Stage (ICPS) that serves as the in-space stage on the initial SLS Block 1 configuration of the rocket. With its larger liquid hydrogen and liquid oxygen propellant tanks feeding four L3 Harris Technologies- built RL10C-3 engines, the EUS generates nearly four times the thrust of the ICPS, providing unrivaled lift capability to the SLS Block 1B and Block 2 rockets and making a new generation of crewed lunar missions possible. This upgraded and more powerful rocket will increase the SLS rocket’s payload to the Moon by 40%, from 27 metric tons (59,525 lbs.) with Block 1 to 38 metric tons (83,776 lbs.) in the crew configuration. Launching crewed missions along with other large payloads enables multiple large-scale objectives to be accomplished in a single mission. Michoud facility quality inspectors Michael Conley, background, and Michael Kottemann perform Ultrasonic Test inspections on the mid-body V-Strut for a structural test article for the SLS rocket’s advanced exploration upper stage in the factory’s new manufacturing area.NASA/Evan Deroche Through the Artemis campaign, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon. The rocket is part of NASA’s deep space exploration plans, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, Gateway in orbit around the Moon, and commercial human landing systems. NASA’s SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

He’s been in love with space ever since he saw a video on the topic in a high school science class. But it wasn’t just any science class. It was one specially designed for English learners. As RS-25’s operations integrator, Chris Pereira is responsible for ensuring that the many pieces of the program – from tracking on-time procurement of supplies and labor loads to coordinating priorities on various in-demand machine centers – come together to deliver a quality product.Mike Labbe, L3Harris Technologies “I was born and raised in Guatemala,” Pereira said. “I came here at 14 unable to speak any English.” Pereira did not know how to navigate the U.S. educational system either, but after that class, he was certain he wanted a career in space. Thus began a journey that ultimately landed him at L3Harris Technologies, where he works in the Aerojet Rocketdyne segment as an engineer and operations integrator on the RS-25 engine – used to power the core stage of NASA’s SLS (Space Launch System) rocket that will launch astronauts to the Moon under NASA’s Artemis campaign. Pereira’s first step was to stay after class and ask to borrow a copy of the video on black holes. His teacher not only obliged but took him across the street to the local library to get his first library card. Pereira quickly recognized that the pathway to his desired career in space was through higher education. It was equally clear, however, that he was not yet on that pathway. English as a Second Language classes, including that science class, did not count toward college admissions. His guidance counselor, meanwhile, was nudging him toward the trades. But with the help of teachers and a new guidance counselor, he got himself on the college-bound track. “I came to understand there were multiple career pathways to explore my interest in space,” Pereira said. “One was engineering.” There was a lot of catching up to do, so Pereira took eight classes per day, including honors courses. He also worked every day after school cleaning a gymnasium from 6 to 11 p.m. to help his family make ends meet. Pereira earned his mechanical engineering degree at California State University at Los Angeles while also working as a senior educator at the California Science Center to cover the cost of his college tuition and living expenses. Pereira’s first career experience was as an intern in manufacturing engineering at Aerojet Rocketdyne. “I learned that making 100% mission-success engines requires a strong culture of attention to detail, teamwork and solid work ethics.” Pereira said. His first full-fledged engineering job was with Honeywell Aerospace working on aircraft programs. Eventually, space came calling – literally. “My mentor at Aerojet Rocketdyne called me up and said, ‘Chris, I have a job for you,’” Pereira said. He began his new job working on rocket engine programs including the AR1 and RS-68 but shifted to the RS-25 after NASA awarded Aerojet Rocketdyne a contract for newly manufactured versions of the engine. Initial versions of the SLS are using refurbished engines from the Space Shuttle Program. Evolved versions of the RS-25 recently concluded a critical test series and will debut with the fifth Artemis flight. As RS-25’s operations integrator, Pereira is responsible for ensuring that the many pieces of the program – from tracking on-time procurement of supplies and labor loads to coordinating priorities on various in-demand machine centers – come together to deliver a quality product. Playing a key role in the nation’s effort to return astronauts to the Moon feels a bit like coming home again, Pereira said. “You develop your first love, work really hard, take different pathways and encounter new passions,” he said. “It’s almost funny how the world and life work out – it’s like I’ve taken a big circle back to my first love.” NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. NASA’s Marshall Space Flight Center manages the SLS Program.

About 300 people attended the event, which coincided with the 25th anniversary of the launch of the Chandra X-ray Observatory. The celebration featured “No Straight Lines,” a new mural at the corner of Clinton Avenue and Washington Street by local artist Float. The mural honors Huntsville’s rich scientific legacy in astrophysics and highlights the groundbreaking discoveries made possible by Marshall scientists and engineers. Other speakers included Collen Wilson-Hodge, principal investigator of the Fermi Gamma-ray Space Telescope. The event also offered members of the community the opportunity to meet the scientists who worked on some of NASA’s most revolutionary astrophysics missions. Featured exhibits from Marshall included the Apollo Telescope mount, the main science instrument on Skylab; the High Energy Astrophysics Program (HEAO); the BATSE instrument on the Compton Gamma-ray Observatory; Chandra X-ray Observatory; Fermi; IXPE (Imaging X-ray Polarimetry Explorer); and Marshall’s X-Ray and Cryogenic Facility. “I had a really nice time at the event,” Weber said. “It’s always great to see such interest and enthusiasm in our science work from the public.” Wilson-Hodge said the mural is an artistic depiction of the historic event detected with the Fermi Gamma-ray Burst Monitor and the Laser Interferometer Gravitational-wave Observatory on Aug. 17, 2017. “On that day, for the first time ever, we observed both a gamma-ray burst and gravitational waves from two very dense neutron stars merging to form a black hole,” she said.

(NASA/Serena Whitfield) › Back to Top Chandra Finds Galaxy Cluster that Crosses the Streams Astronomers using NASA’s Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure. Researchers have discovered an enormous, comet-like tail of hot gas – spanning over 1.6 million light-years long – trailing behind a galaxy within the galaxy cluster called Zwicky 8338, or Z8338.X-ray: NASA/CXC/Xiamen Univ./C. Ge; Optical: DESI collaboration; Image Processing: NASA/CXC/SAO/N. Wolk Researchers have discovered an enormous, comet-like tail of hot gas – spanning over 1.6 million light-years long – trailing behind a galaxy within the galaxy cluster called Zwicky 8338 (Z8338 for short). This tail, spawned as the galaxy had some of its gas stripped off by the hot gas it is hurtling through, has split into two streams. This is the second pair of tails trailing behind a galaxy in this system. Previously, astronomers discovered a shorter pair of tails from a different galaxy near this latest one. This newer and longer set of tails was only seen because of a deeper observation with Chandra that revealed the fainter X-rays. Astronomers now have evidence that these streams trailing behind the speeding galaxies have crossed one another. Z8338 is a chaotic landscape of galaxies, superheated gas, and shock waves (akin to sonic booms created by supersonic jets) in one relatively small region of space. These galaxies are in motion because they were part of two galaxy clusters that collided with each other to create Z8338. This new composite image shows this spectacle. X-rays from Chandra (represented in purple) outline the multimillion-degree gas that outweighs all of the galaxies in the cluster. The Chandra data also shows where this gas has been jettisoned behind the moving galaxies. Meanwhile an optical image from the Dark Energy Survey from the Cerro Tololo Inter-American Observatory in Chile shows the individual galaxies peppered throughout the same field of view. The original gas tail discovered in Z8338 is about 800,000 light-years long and is seen as vertical in this image. The researchers think the gas in this tail is being stripped away from a large galaxy as it travels through the galaxy cluster. The head of the tail is a cloud of relatively cool gas about 100,000 light-years away from the galaxy it was stripped from. This tail is also separated into two parts. A labeled version of the galaxy cluster Zwicky 8338.X-ray: NASA/CXC/Xiamen Univ./C. Ge; Optical: DESI collaboration; Image Processing: NASA/CXC/SAO/N. Wolk The team proposes that the detachment of the tail from the large galaxy may have been caused by the passage of the other, longer tail. Under this scenario, the tail detached from the galaxy because of the crossing of the streams. The results give useful information about the detachment and destruction of clouds of cooler gas like those seen in the head of the detached tail. This work shows that the cloud can survive for at least 30 million years after it is detached. During that time, a new generation of stars and planets may form within it. The Z8338 galaxy cluster and its jumble of galactic streams are located about 670 million light-years from Earth. A paper describing these results appeared in the Aug. 8, 2023, issue of the Monthly Notices of the Royal Astronomical Society and is available here.

NASA/Joel Kowsky NASA launched its reimagined art program by unveiling two murals on Sept. 23, 2024. The murals, titled “To the Moon, and Back,” were created by New York-based artist team Geraluz and WERC and use geometrical patterns to invite deeper reflection on the exploration, creativity, and connection with the cosmos. The vision of this next phase is to inspire and engage the Artemis Generation with community murals and other art projects for the benefit of humanity. NASA has long used art to tell the story of its awe-inspiring missions. Soon after its inception, the agency started a formal program commissioning artists to develop inspiring pieces like portraits and paintings that highlighted an unexpected side of the agency. In 1962, NASA’s then Administrator James Webb tasked staffer and artist James Dean with implementing the new program, and with the help of the National Gallery of Art, Dean laid the framework to artistically capture the inspiration of NASA’s Apollo program. As the NASA Art Program continues to evolve, the agency remains focused on inspiring and engaging the next generation of explorers – the Artemis Generation – in new and unexpected ways, including through art.

As systems integration team lead for NASA’s Commercial Low Earth Orbit Development Program (CLDP), Hector Chavez helps build a future where NASA and private industry work together to push the boundaries of space exploration. With the rise of commercial providers in the space sector, Chavez’s team works to ensure that these companies can develop end-to-end systems to support NASA’s low Earth orbit operations—from transporting crew and cargo to operating mission centers. His team’s role is to assess how commercial providers are using their systems engineering processes to achieve program goals and objectives. Official portrait of Hector Chavez. NASA/David DeHoyos With a background that spans both the National Nuclear Security Administration and NASA, Chavez brings knowledge and insight into working with interdisciplinary teams to create complex, reliable systems. He has collaborated across organizations, contracts, and government to ensure design and operational improvements were carried out safely and reliably. “Systems integration brings different systems together to deliver capabilities that can’t be achieved alone,” said Chavez. His previous role in NASA’s Safety and Mission Assurance office deepened his expertise in mitigating technical risks in human spaceflight by integrating engineering, health, and safety considerations into the development of space exploration vehicles. Hector Chavez and the team prepare to lift and install a receiver telescope assembly for the Optical Development System, used to test the alignment and performance of the optical systems for NASA’s Ice, Cloud, and land Elevation Satellite-2 mission, in a clean room at Goddard Space Flight Center in Greenbelt, Maryland.NASA Now with CLDP, Chavez helps these companies navigate NASA’s design processes without stifling innovation. “Our challenge is to communicate what we’ve identified during technical reviews without prohibiting commercial partners from developing innovative solutions,” he said. One recent success was the team’s development of two technical standards for docking systems and payload interfaces that will help ensure these systems’ compatibility with existing technologies. This work is essential in allowing commercial low Earth orbit systems to seamlessly integrate with NASA’s heritage designs, a key step toward realizing the agency’s vision for sustained commercial operations in space. When asked about the biggest opportunities and challenges in his role, Chavez emphasizes the importance of early collaboration. By engaging with commercial partners at the early stages of the system development life cycle, NASA can provide feedback that shapes the future of commercial low Earth orbit architecture. “We identify technical issues and lessons learned without dictating design solutions, allowing for innovation while ensuring safety and reliability,” explained Chavez. Hector Chavez receives an award from the U.S. Department of Energy. Chavez’s approach to leadership and teamwork is rooted in his values of perseverance, integrity, and encouragement. These principles have helped guide the development of CLDP’s mission and vision statements, creating an environment that promotes collaboration and creativity. He is passionate about building a team culture where people feel empowered to take responsible risks and explore solutions. Hector Chavez receives a Silver Snoopy Award with his family at NASA’s Johnson Space Center in Houston.

NASA/Evan Deroche Manufacturing equipment that will be used to build components for NASA’s SLS (Space Launch System) rocket for future Artemis missions is being installed at the agency’s Michoud Assembly Facility in New Orleans, Louisiana. The novel tooling will be used to produce the SLS rocket’s advanced exploration upper stage, or EUS, in the factory’s new manufacturing area. The EUS will serve as the upper, or in-space, stage for all Block 1B and Block 2 SLS flights in both crew and cargo configurations. In tandem, NASA and Boeing, the SLS lead contractor for the core stage and exploration upper stage, are producing structural test articles and flight hardware structures for the upper stage at Michoud and the agency’s Marshall Space Flight Center in Huntsville, Alabama. Early manufacturing is already underway at Michoud while preparations for an engine-firing test series for the upper stage are in progress at nearby Stennis Space Center in Bay St. Louis, Mississippi. “The newly modified manufacturing space for the exploration upper stage signifies the start of production for the next evolution of SLS Moon rockets at Michoud,” said Hansel Gill, director at Michoud. “With Orion spacecraft manufacturing and SLS core stage assembly in flow at Michoud for the past several years, standing up a new production line and enhanced capability at Michoud for EUS is a significant achievement and a reason for anticipation and enthusiasm for Michoud and the SLS Program.” The advanced upper stage for SLS is planned to make its first flight with Artemis IV and replaces the single-engine Interim Cryogenic Propulsion Stage (ICPS) that serves as the in-space stage on the initial SLS Block 1 configuration of the rocket. With its larger liquid hydrogen and liquid oxygen propellant tanks feeding four L3 Harris Technologies- built RL10C-3 engines, the EUS generates nearly four times the thrust of the ICPS, providing unrivaled lift capability to the SLS Block 1B and Block 2 rockets and making a new generation of crewed lunar missions possible. This upgraded and more powerful rocket will increase the SLS rocket’s payload to the Moon by 40%, from 27 metric tons (59,525 lbs.) with Block 1 to 38 metric tons (83,776 lbs.) in the crew configuration. Launching crewed missions along with other large payloads enables multiple large-scale objectives to be accomplished in a single mission. Through the Artemis campaign, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon. The rocket is part of NASA’s deep space exploration plans, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, Gateway in orbit around the Moon, and commercial human landing systems. NASA’s SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. NASA’s Marshall Space Flight Center manages the SLS Program and Michoud.

3 Min Read NASA’s Record-Breaking Laser Demo Completes Mission An artist's concept animation of NASA's TeraByte InfraRed Delivery (TBIRD) payload sending data to Earth over laser communications links. Credits: NASA NASA’s TBIRD (TeraByte InfraRed Delivery) demonstration and its host spacecraft — the PTD-3 (Pathfinder Technology Demonstrator-3) — have completed their technology demonstration. The TBIRD payload spent the past two years breaking world records for the fastest satellite downlink from space using laser communications. NASA’s PTD series leverages a common commercial spacecraft to provide a robust platform for effective testing of technologies with minimal redesign in between launches. After launch in May 2022 on the SpaceX Transporter 5 mission, the PTD-3 spacecraft entered low-Earth orbit and shortly after TBIRD began sending laser communications signals to an optical ground station in Table Mountain, California. An artist’s concept of the Pathfinder Technology Demonstration -3 carrying the TeraByte InfraRed Delivery payload. NASA/Dave Ryan TBIRD’s two-year demonstration showcased the viability of laser communications. Most NASA missions rely on radio frequency communication systems, however, laser communications use infrared light and can pack significantly more data in a single communications link. This technology is ideal for science and exploration missions that need large data transmissions. In 2023, TBIRD continuously broke its own records, reaching its peak in June when it transmitted 4.8 terabytes of error-free data — equivalent to about 2,400 hours of high-definition video — in five minutes at 200 gigabits per second in a single pass. The benefits of laser communications: more efficient, lighter systems, increased security, and more flexible ground systems.Credits: NASA/Dave Ryan The TBIRD payload was one of many laser communications demonstrations. NASA’s SCaN (Space Communications and Navigation) program is maturing this technology to demonstrate the impact laser communications can have for bringing more science and exploration data home. The next demonstration will be on the Artemis II mission. NASA’s Laser Communications Roadmap – proving the technology’s validity in a variety of environments.NASA/Dave Ryan In addition to breaking a world record, this mission demonstrated cost-effective design and extremely low size, weight, and power requirements — both on the PTD-3 spacecraft and within the TBIRD payload. The tissue-box-sized payload contained two commercial telecommunication modems that the TBIRD team modified for the extreme environment of space. The completed TeraByte InfraRed Delivery (TBIRD) payload at the Massachusetts Institute of Technology Lincoln Laboratory. Massachusetts Institute of Technology Lincoln Laboratory The PTD-3/TBIRD system also overcame one of the major challenges associated with laser communications: making the narrow beam laser link connection while moving at orbital speeds while being buffeted by atmospheric drag. The PTD-3 spacecraft’s precision “body pointing” and stability enabled the TBIRD payload to make its record-breaking achievement while moving as fast as 17,000 mph through space. The spacecraft set a record for the highest accuracy pointing ever achieved by a NASA CubeSat without any moving mechanisms or propulsion systems.

The system did not contain a propulsion system, meaning once it was deployed into its low Earth orbit, the mission could only last until its orbit naturally decayed. While only planned to operate for six months, TBIRD carried out its demonstration for well over two years, enabling NASA to learn more about laser communications operations in low Earth orbit. The lessons learned during TBIRD will be applied to future implementations of laser communications and minimize downlink constraints for mission designs enabling future exploration and discoveries. All of the PTD-3/TBIRD accomplishments were made possible by collaborations across NASA centers and beyond. TBIRD was a collaborative effort among NASA’s Goddard Space Flight Center in Greenbelt, Maryland; NASA’s Ames Research Center in California’s Silicon Valley; NASA’s Jet Propulsion Laboratory in Southern California; the Massachusetts Institute of Technology Lincoln Laboratory in Lexington, Massachusetts; and Terran Orbital Corporation in Irvine, California. Funding and oversight for the TBIRD payload came from NASA’s SCaN (Space Communications and Navigation) program office within the Space Operations Mission Directorate at NASA Headquarters. The PTD-3 mission was managed and funded by the Small Spacecraft Technology program within NASA’s Space Technology Mission Directorate.

NASA’s HERA (Human Exploration Research Analog) crew members enjoy their first glimpse of the outside after a 45-day stay inside the analog environment. From left to right: Sergii Iakymov, Sarah Elizabeth McCandless, Erin Anderson, and Brandon Kent.NASA/Bill Stafford An all-volunteer crew on a simulated trip to Mars “returned” to Earth on Sept. 23, 2024, after being isolated in a tiny habitat at Johnson Space Center in Houston. Their work is contributing to the science that will propel humanity to the Moon and eventually Mars. The HERA missions provide valuable scientific insights into how humans may respond to the confinement, demanding work-life conditions, and remote environments that astronauts may encounter on deep space missions. These insights help NASA prepare for humanity’s next giant leap to the Moon and Mars. Campaign 7 Mission 3 started when HERA operations lead Ted Babic rang the bell outside the habitat 10 times, a ceremonial send-off wishing the crew a safe and successful simulated mission to Mars. Seven rings honored the campaign, and three more signaled the mission—continuing a long-standing tradition. At ingress, Anderson, a structural engineer at NASA’s Langley Research Center in Virginia, told HERA’s mission control, “We’re going to take good care of this ship of yours on our journey.” The HERA crew members wave goodbye to friends, family, and support staff before entering the analog environment on Aug. 9, 2024.NASA/James Blair Life on a 45-Day Journey The HERA crew members participated in 18 human health and performance studies, seven of which were led by scientists from outside the United States. These international studies are in collaboration with the United Arab Emirates’ Mohammed Bin Rashid Space Centre and the European Space Agency. HERA crew members inside the analog environment at NASA’s Johnson Space Center in Houston. From left: Sarah Elizabeth McCandless, Brandon Kent, Erin Anderson, and Sergii Iakymov.NASA/Bill Stafford Throughout the simulation, the crew performed a variety of tasks. They harvested plants from a hydroponic garden, grew shrimp, deployed a small cube satellite to simulate data gathering, conducted a virtual reality “walk” on the surface of Mars, and flew simulated drones on the Martian terrain. These activities are designed to immerse the crew in the task-focused mindset of astronauts. NASA scientists then monitor HERA crew to assess how routine tasks, along with isolation and confinement, impact behavior and performance. As their mission progressed, the team experienced longer communication delays with mission control, eventually reaching five-minute lags. This simulates the challenges astronauts might face on Mars, where delays could be up to 20 minutes. Scientists studying HERA crew are interested to see how this particular group builds independent, autonomous workflows, despite this communication delay. Here are some snapshots of crew activities: McCandless holds a skeletal framework of a Mars rover. She is wearing augmented reality glasses that allow her to project various scientific hardware as holograms. The final product will be a Mars rover that she ‘built’ herself. NASA Kent and Anderson, seen through an airlock window separating rooms inside HERA, conduct a virtual reality EVA on the Mars surface.

Iakymov examines water quality and temperature in a tank that holds a few triops shrimp that he and his crewmates raised.NASA McCandless and Anderson work out on HERA’s second floor. They are holding power blocks, dumbbells equipped with weights that can adjust to a maximum of 35 pounds. The blocks take up less space than a set of regular dumbbells, helping to save space in the tiny habitat.NASA All crew members brought books to accompany them on their journey to the Red Planet, while Kent left behind letters for his two daughters to open each day. McCandless also brought letters from loved ones, along with Legos, her favorite card game, and a vintage iPod. Iakymov, an aerospace engineer with more than 15 years of experience in research and design, is carrying postcards and photos of family and friends. Anderson, who describes herself as a massive space nerd, brought extra socks and “The Never Ending Story,” a book she has cherished throughout her life. The crew all shared appreciation for being part of a mission that contributes to the aspirations of future human space exploration travel. The crew holds up varieties of lettuce grown in hydroponic units inside HERA. NASA Returning to Earth As the mission neared its end, McCandless and Anderson participated in a Groundlink—a live session connecting them with middle school students in a classroom in Coconut Grove, Florida, and in Olathe, Kansas. Groundlinks provide a unique opportunity for students to engage directly with crew members and learn about the realities of long-duration missions. The students asked the crew about life inside the habitat, the challenges of isolation, and what it might be like to live on Mars. They were also curious about the crew’s favorite foods and activities. McCandless shared her love for cheddar crisps and freeze-dried Pad Thai and proudly showed off favorite sports teams from her home state of Kansas, much to the cheers of the crowd. Anderson displayed the massive collection of comics and fantasy books that she read inside the habitat. In the late afternoon of Sept. 23, 2024, the crew egressed from HERA, marking the end of their 45-day simulated mission to Mars. After stepping out of the habitat, the crew expressed gratitude for the opportunity and reflected on the mission’s significance. “Following our safe passage to Mars, and our safe return to Earth, as the crew of Campaign 7, Mission 3, we hereby officially transfer this exploration vessel to the flight analogs operations team,” said Kent. “We hope this vessel continues to serve as a safe home for future HERA crews.” Want to Participate in HERA? NASA is actively seeking healthy, non-smoking volunteers, aged 30 to 55, for future HERA missions. Volunteers, who will be compensated for their participation, must pass a physical and psychological assessment to qualify.

Ruidoso, New Mexico lay in an unusual hush on June 20, 2024. During any normal summer day, the village in the southern part of the state lives up to the Spanish translation of its name — noisy. But the bustle of this vacation hotspot, which attracts nearly 2 million visitors each year, was stifled by a mandatory evacuation order issued as wildfires raged unchecked across Lincoln County and the Mescalero Apache Reservation.  After four days of fires, news of the disaster began spreading to surrounding communities. Wildfires cast an orange haze over the Sierra Blanca mountain range in Ruidoso, New Mexico, on June 20, 2024. Image courtesy of James Herrera At NASA’s White Sands Test Facility (WSTF), Fire Department Deputy Chief James Herrera and his team were on high alert from the moment the blaze began.  “There were so many rumors, so many things going on,” Herrera said. “People were saying the town was completely burning down. We were expecting the worst before we even got there.” Herrera’s expectations were realistic.  Tinderbox conditions, rough terrain, and winds reaching more than 70 miles per hour fueled the flames raging at the South Fork area west of Ruidoso, devouring nearly 5,000 acres just hours after the fire started. As first responders expended every resource available to them both on the ground and in the air, a second fire — the Salt Fire — broke out on tribal land south of the village. Now the twin infernos closed in on Ruidoso like a set of jaws poised to snap shut.  Gov. Michelle Lujan Grisham quickly declared a state of emergency and the early whispers crescendoed into an urgent plea for aid from anyone who would listen. There was no doubt in Herrera’s mind: WSTF, based 150 miles from Ruidoso in Las Cruces, New Mexico, would answer the call.  “Never once did [WSTF leadership] say ‘Sorry, we can’t help,’” he said. “They asked, ‘What can we do to help? How can we get there as soon as possible?’”  Shift changes made for an earliest possible departure at dawn on June 20. The WSTF Fire Department spent the night preparing their truck, gathering their belongings, and bracing for the uncertain. “We didn’t know where we were going to sleep, there were no hotels, everything was closed,” Herrera said. “More than likely, we were going to end up sleeping in our engine.” For the moment, rest was off the table.  “I’m not going to lie, we probably didn’t even sleep. I know I didn’t,” Herrera said. “I closed my eyes, and it was two o’clock in the morning. Time to get going.” After checking in at the Incident Command Post, Herrera and the WSTF team — Lieutenant Gary Sida, firefighters Steven Olsson and Gabriel Rodriguez, and driver and engineer Tommy Montoya — were deployed to Ruidoso’s Casino Apache Travel Center off Highway 70. Deputy Chief James Herrera (far left) and his crew (L-R) Driver/Operator Tommy Montoya, Firefighter Gabe Rodriguez (top), Lieutenant Gary Sida, and Firefighter Stephen Olsson return to a hero’s welcome at White Sands Test Facility in Las Cruces, New Mexico. NASA/Anthony Luis Quiterio When Herrera and his four-man crew reached the edge of the deserted mountain town, the silence was more than unusual. It was unsettling, as heavy as the smoke suffocating the Sierra Blanca Peak. “You could not see more than 100 feet,” Herrera said. “The only sign of life was all the fire agencies that were there. It was an eerie feeling.” NASA’s arrival on scene brought a shift from anxiety to optimism and relief. “There were tears in some of their eyes because we were showing up to help,” he said. “I could hear people saying, ‘What’s NASA doing here?’” He added, “One gentleman asked us how we got there. I joked that we drove the whole line from Kennedy Space Center.” By the afternoon, the light-heartedness among comrades was extinguished as escalating winds charged the situation to a fever pitch. The fire, once perched atop the mountains, began hurling down in a landslide of embers, leaping across Highway 70, and forming a nearly complete ring of danger. Breathing grew difficult as ground crews, with aerial units roaring overhead, battled a relentless assault of heat. WSTF Fire Department’s assignment evolved into an effort to protect anything and everything within reach. “It makes you realize how fast something can be taken away from you,” Herrera said.

Image courtesy of James Herrera Though disaster descended in an instant, the day itself had been long. Herrera and his team were released from duty after a grueling 12 hours spent providing critical support to wildland units and successfully protecting nearby buildings. “Once it starts to calm down, you can feel your hands start to shake a little bit because this thing was getting out of control really fast,” Herrera said.  By the weekend, containment efforts were gaining ground thanks to the efforts of a combined 780-strong emergency response force. Eager to rebuild, Ruidoso residents trickled back in, but the village soon encountered another challenge: rain. Following the South Fork and Salt fires — which claimed an estimated 25,000 acres, 1,400 structures, and two lives — monsoons battered Ruidoso. Throughout July, deluges washed over the region’s burn scars in an ironic insult to injury leaving people trapped in vehicles and homes underwater. As recently as Aug. 7, evacuations continued as the Ruidoso Police Department worked to preemptively clear the Cherokee Mobile Village due to past flash flooding in the area.  In this harsh landscape of crisis and aftermath, Herrera views mutual aid as more than a tactical response, but a vital investment. “Building goodwill with the community is akin to cultivating fertile ground for growth and success,” he said. “I strongly feel it strengthens the bond between us and our community.”  With the wet season expected to continue through the end of September, Ruidoso’s forecast remains uncertain. Even as storm clouds gather, one thing is clear: if the call comes again, the WSTF Fire Department will always be ready to answer. View the full article
