5 Min Read Reinventing the Clock: NASA’s New Tech for Space Timekeeping The Optical Atomic Strontium Ion Clock is a higher-precision atomic clock that is small enough to fit on a spacecraft. Credits: NASA/Matthew Kaufman Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellites to pinpoint locations. Three teams at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are at work to push timekeeping for space exploration to new levels of precision. One team develops highly precise quantum clock synchronization techniques to aid essential spacecraft communication and navigation. Another Goddard team is working to employ the technique of clock synchronization in space-based platforms to enable telescopes to function as one enormous observatory. The third team is developing an atomic clock for spacecraft based on strontium, a metallic chemical element, to enable scientific observations not possible with current technology. The need for increasingly accurate timekeeping is why these teams at NASA Goddard, supported by the center’s Internal Research and Development program, hone clock precision and synchronization with innovative technologies like quantum and optical communications. Syncing Up Across the Solar System “Society requires clock synchronization for many crucial functions like power grid management, stock market openings, financial transactions, and much more,” said Alejandro Rodriguez Perez, a NASA Goddard researcher. “NASA uses clock synchronization to determine the position of spacecraft and set navigation parameters.” If you line up two clocks and sync them together, you might expect that they will tick at the same rate forever. In reality, the more time passes, the more out of sync the clocks become, especially if those clocks are on spacecraft traveling at tens of thousands of miles per hour. Rodriguez Perez seeks to develop a new way of precisely synchronizing such clocks and keeping them synced using quantum technology. Work on the quantum clock synchronization protocol takes place in this lab at NASA’s Goddard Space Flight Center in Greenbelt, Md.NASA/Matthew Kaufman In quantum physics, two particles are entangled when they behave like a single object and occupy two states at once. For clocks, applying quantum protocols to entangled photons could allow for a precise and secure way to sync clocks across long distances. The heart of the synchronization protocol is called spontaneous parametric down conversion, which is when one photon breaks apart and two new photons form. Two detectors will each analyze when the new photons appear, and the devices will apply mathematical functions to determine the offset in time between the two photons, thus synchronizing the clocks. While clock synchronization is currently done using GPS, this protocol could make it possible to precisely synchronize clocks in places where GPS access is limited, like the Moon or deep space. Syncing Clocks, Linking Telescopes to See More than Ever Before When it comes to astronomy, the usual rule of thumb is the bigger the telescope, the better its imagery. “If we could hypothetically have a telescope as big as Earth, we would have incredibly high-resolution images of space, but that’s obviously not practical,” said Guan Yang, an optical physicist at NASA Goddard. “What we can do, however, is have multiple telescopes in various locations and have each telescope record the signal with high time precision. Then we can stich their observations together and produce an ultra-high-res image.” The idea of linking together the observations of a network of smaller telescopes to affect the power of a larger one is called very long baseline interferometry, or VLBI. For VLBI to produce a whole greater than the sum of its parts, the telescopes need high-precision clocks. The telescopes record data alongside timestamps of when the data was recorded. High-powered computers assemble all the data together into one complete observation with greater detail than any one of the telescopes could achieve on its own. This technique is what allowed the Event Horizon Telescope’s network of observatories to produce the first image of a black hole at the center of our galaxy. The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Although the telescopes making up the EHT are not physically connected, they are able to synchronize their recorded data with atomic clocks.EHT Collaboration Yang’s team is developing a clock technology that could be useful for missions looking to take the technique from Earth into space which could unlock many more discoveries. An Optical Atomic Clock Built for Space Travel Spacecraft navigation systems currently rely on onboard atomic clocks to obtain the most accurate time possible. Holly Leopardi, a physicist at NASA Goddard, is researching optical atomic clocks, a more precise type of atomic clock. While optical atomic clocks exist in laboratory settings, Leopardi and her team seek to develop a spacecraft-ready version that will provide more precision. The team works on OASIC, which stands for Optical Atomic Strontium Ion Clock. While current spacecraft utilize microwave frequencies, OASIC uses optical frequencies. The Optical Atomic Strontium Ion Clock is a higher-precision atomic clock that is small enough to fit on a spacecraft.NASA/Matthew Kaufman “Optical frequencies oscillate much faster than microwave frequencies, so we can have a much finer resolution of counts and more precise timekeeping,” Leopardi said. The OASIC technology is about 100 times more precise than the previous state-of-the-art in spacecraft atomic clocks. The enhanced accuracy could enable new types of science that were not previously possible. “When you use these ultra-high precision clocks, you can start looking at the fundamental physics changes that occur in space,” Leopardi said, “and that can help us better understand the mechanisms of our universe.” The timekeeping technologies unlocked by these teams, could enable new discoveries in our solar system and beyond.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) While astronaut Gene Cernan was on the lunar surface during the Apollo 17 mission, his spacesuit collected loads of lunar dust. The gray, powdery substance stuck to the fabric and entered the capsule causing eye, nose, and throat irritation dubbed “lunar hay fever.” Credit: NASACredit: NASA Moon dust, or regolith, isn’t like the particles on Earth that collect on bookshelves or tabletops – it’s abrasive and it clings to everything. Throughout NASA’s Apollo missions to the Moon, regolith posed a challenge to astronauts and valuable space hardware. During the Apollo 17 mission, astronaut Harrison Schmitt described his reaction to breathing in the dust as “lunar hay fever,” experiencing sneezing, watery eyes, and a sore throat. The symptoms went away, but concern for human health is a driving force behind NASA’s extensive research into all forms of lunar soil. The need to manage the dust to protect astronaut health and critical technology is already beneficial on Earth in the fight against air pollution. Working as a contributor on a habitat for NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) program, Lunar Outpost Inc. developed an air-quality sensor system to detect and measure the amount of lunar soil in the air that also detects pollutants on Earth. Originally based in Denver, the Golden, Colorado-based company developed an air-quality sensor called the Space Canary and offered the sensor to Lockheed Martin Space for its NextSTEP lunar orbit habitat prototype. After the device was integrated into the habitat’s environmental control system, it provided distinct advantages over traditional equipment. Rebranded as Canary-S (Solar), the sensor is now meeting a need for low-cost, wireless air-quality and meteorological monitoring on Earth. The self-contained unit, powered by solar energy and a battery, transmits data using cellular technology. It can measure a variety of pollutants, including particulate matter, carbon monoxide, methane, sulfur dioxide, and volatile organic compounds, among others. The device sends a message up to a secure cloud every minute, where it’s routed to either Lunar Outpost’s web-based dashboard or a customer’s database for viewing and analysis. The oil and gas industry uses the Canary-S sensors to provide continuous, real-time monitoring of fugitive gas emissions, and the U.S. Forest Service uses them to monitor forest-fire emissions. “Firefighters have been exhibiting symptoms of carbon monoxide poisoning for decades. They thought it was just part of the job,” explained Julian Cyrus, chief operating officer of Lunar Outpost. “But the sensors revealed where and when carbon monoxide levels were sky high, making it possible to issue warnings for firefighters to take precautions.” The Canary-S sensors exemplify the life-saving technologies that can come from the collaboration of NASA and industry innovations.

Credit: NASA NASA has awarded a contract to Intuitive Machines, LLC of Houston, to support the agency’s lunar relay systems as part of the Near Space Network, operated by the agency’s Goddard Space Flight Center in Greenbelt, Maryland. This Subcategory 2.2 GEO to Cislunar Relay Services is a new firm-fixed-price, multiple award, indefinite-delivery/indefinite-quantity task order contract. The contract has a base period of five years with an additional 5-year option period, with a maximum potential value of $4.82 billion. The base ordering period begins Tuesday, Oct. 1, 2024, through Sept. 30, 2029, with the option period potentially extending the contract through Sept. 30, 2034. Lunar relays will play an essential role in NASA’s Artemis campaign to establish a long-term presence on the Moon. These relays will provide vital communication and navigation services for the exploration and scientific study of the Moon’s South Pole region. Without the extended coverage offered by lunar relays, landing opportunities at the Moon’s South Pole will be significantly limited due to the lack of direct communication between potential landing sites and ground stations on Earth. The lunar relay award also includes services to support position, navigation, and timing capabilities, which are crucial for ensuring the safety of navigation on and around the lunar surface. Under the contract, Intuitive Machines also will enable NASA to provide communication and navigation services to customer missions in the near space region. The initial task award will support the progressive validation of lunar relay capabilities/services for Artemis. NASA anticipates these lunar relay services will be used with human landing systems, the LTV (lunar terrain vehicle), and CLPS (Commercial Lunar Payload Services) flights. As lunar relay services become fully operational, they will be integrated into the Near Space Network’s expanding portfolio, enhancing communications and navigation support for future lunar missions. By implementing these new capabilities reliance on NASA’s Deep Space Network will be reduced. NASA’s goal is to provide users with communication and navigation services that are secure, reliable, and affordable, so that all NASA users receive the services required by their mission within their latency, accuracy, and availability requirements. This is another step in NASA partnering with U.S. industry to build commercial space partners to support NASA missions, including NASA’s long-term Moon to Mars objectives for interoperable communications and navigation capabilities. This award is part of the Space Communications and Navigation (SCaN) Program and will be executed by the Near Space Network team at NASA Goddard.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Back to Fire Science Landing Page FireSense The FireSense project is focused on delivering NASA’s unique Earth science and technological capabilities to operational agencies, striving to address challenges in US wildland fire management. The project concentrates on four use-cases to support decisions before, during, and after wildland fires. These include the measurement of pre-fire fuels conditions, active fire dynamics, post fire impacts and threats, as well as air quality forecasting, each co-developed with identified wildland fire management agency stakeholders. Strategic Tac Radio and Tac Overwatch (STRATO) The Strategic Tac Radio and Tac Overwatch (STRATO) system is designed to provide real-time fire observations and last-mile communications with firefighters from stratospheric platforms. By providing persistent communications to a wildfire response team for a week or longer, STRATO is expected to offer capabilities beyond the currently used tethered balloons, which have a limited range and coverage area. By achieving station-keeping at altitudes up to 70,000 feet above ground level—to be demonstrated in flight testing—the STRATO will be able to provide communications to incident response teams in areas with no cellphone coverage. Surface Biology and Geology (SBG) Arctic Boreal Vulnerability Experiment (ABoVE) Climate change in the Arctic and Boreal region is unfolding faster than anywhere else on Earth, resulting in reduced Arctic sea ice, thawing of permafrost soils, decomposition of long- frozen organic matter, widespread changes to lakes, rivers, coastlines, and alterations of ecosystem structure and function. NASA’s Terrestrial Ecology Program is conducting a major field campaign, the Arctic-Boreal Vulnerability Experiment (ABoVE), in Alaska and western Canada, from 2015 – 2025. ABoVE seeks a better understanding of the vulnerability and resilience of ecosystems and society to this changing environment.

Credit: NASA NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected Lockheed Martin Corp. of Littleton, Colorado, to develop a lightning mapping instrument as part of NOAA’s Geostationary Extended Observations (GeoXO) satellite program. This cost-plus-award-fee contract is valued at approximately $297.1 million. It includes the development of two flight instruments as well as options for two additional units. The anticipated period of performance for this contract includes support for 10 years of on-orbit operations and five years of on-orbit storage, for a total of 15 years for each flight model. The work will take place at Lockheed Martin’s facilities in Sunnyvale, California, and Littleton, Colorado, NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the agency’s Kennedy Space Center in Florida. The GeoXO Lightning Mapper will detect, locate, and measure the intensity, duration, and extent of lightning flashes. The instrument will continue critical observations provided by the Geostationary Operational Environmental Satellites-R (GOES-R) Series Geostationary Lightning Mapper. Data from Lightning Mapper will be used to analyze severe storms, increase warning lead time for hazardous weather, and provide earlier indications of impending lightning strikes to the ground. The data will also be used for hurricane intensity prediction, wildfire detection and response, precipitation estimation, and to mitigate aviation hazards. Forecasters need lightning information from geostationary orbit because the data are available where other sources are more limited, especially over oceans and in mountainous and rural areas. The data are also available more frequently than local radar and fill in radar coverage gaps. The contract scope includes the tasks and deliverables necessary to design, analyze, develop, fabricate, integrate, test, verify, and evaluate the lightning mapper instrument in addition to supporting the launch; supplying and maintaining the instrument ground support equipment; and supporting mission operations at the NOAA Satellite Operations Facility in Suitland, Maryland. The GeoXO Program is the follow-on to the GOES-R Series Program. The GeoXO satellite system will advance Earth observations from geostationary orbit. The mission will supply vital information to address major environmental challenges of the future in support of weather, ocean, and climate operations in the United States. The advanced capabilities from GeoXO will help address our changing planet and the evolving needs of the nation’s data users. Both NASA and NOAA are working to ensure these critical observations are in place by the early 2030s when the GOES-R Series nears the end of its operational lifetime. Together, NOAA and NASA oversee the development, launch, testing, and operation of all the satellites in the GeoXO Program. NOAA funds and manages the program, operations, and data products. On behalf of NOAA, NASA and commercial partners develop and build the instruments and spacecraft and launch the satellites.

This kind of research enables more informed ecological management and conservation efforts, and broadens our understanding of how different ecosystems are reacting to a changing climate. https://www.nasa.gov/nasa-earth-exchange-nex/new-missions-support/internet-of-animals/ FATE: dFAD Trajectory Tool FATE will quantify dFAD (drifting fish aggregating devices) activity in relation to ocean currents, fish biomass, and animal telemetry at Palmyra Atoll, which is a U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge and is part of the U.S. Pacific Remote Islands Marine National Monument (PRIMNM) in the central Pacific Ocean. This innovative decision support tool will use NASA observations and numerical models to predict future dFAD trajectories and inform resource managers whether they should deploy tactical resources (boats, personnel) to monitor, intercept, or retrieve dFADs that have entered the MPA. SeaSTAR SeaSTAR aims to provide multi-spectral aerosol optical depth (AOD) and aerosol optical properties using a custom-built robotic sun/sky photometer. The instrument is designed to operate from a ship and is planned to deploy aboard the NOAA research vessel RV Shearwater in September 2024 to support the PACE-PAX airborne campaign. PACE Validation Science Team Project: AirSHARP Airborne asSessment of Hyperspectral Aerosol optical depth and water-leaving Reflectance Product Performance for PACE The goal of AirSHARP is to provide high fidelity spatial coverage and spectral data for ocean color and aerosol products for validation of the PACE Ocean Color Instrument (OCI). Coastal influences on oceanic waters can produce high optical complexity for remote sensing especially in dynamic waters in both space and time. Dynamic coastal water features include riverine plumes (sediments and pollution), algal blooms, and kelp beds. Further, coastal California has a range of atmospheric conditions related to fires. We will accomplish validation of PACE products by combined airborne and field instrumentation for Monterey Bay, California. Water2Coasts Watersheds, Water Quality, and Coastal Communities in Puerto Rico Water2Coasts is an interdisciplinary island landscape to coastal ocean assessment with socioeconomic implications. The goal of Water2Coasts is to conduct a multi-scale, interdisciplinary (i.e., hydrologic, remote sensing, and social) study on how coastal waters of east, and south Puerto Rico are affected by watersheds of varying size, land use, and climate regimes, and how these may in turn induce a variety of still poorly understood effects on coastal and marine ecosystems such as coral reefs and seagrass beds. US Coral Reef Task Force (USCRTF) The USCRTF was established in 1998 by Presidential Executive Order to lead U.S. efforts to preserve and protect coral reef ecosystems. The USCRTF includes leaders of Federal agencies, U.S. States, territories, commonwealths, and Freely Associated States. The USCRTF helps build partnerships, strategies, and support for on-the-ground action to conserve coral reefs. NASA ARC scientists are members of the Steering Committee, Watershed Working Group, and Disease and Disturbance Working Group, and lead the Climate Change Working Group to assist in the use of NASA remote sensing data and tools for coastal studies, including coral reef ecosystems. Data from new and planned hyperspectral missions will advance research in heavily impacted coastal ecosystems. CyanoSCape Cyanobacteria and surface phytoplankton biodiversity of the Cape freshwater systems The diversity of phytoplankton is also found in freshwater systems. In Southern Africa, land use change and agricultural practices has hindered hydrological processes and compromised freshwater ecosystems. These impacts are compounded by increasingly variable rainfall and temperature fluctuations associated with climate change posing risks to water quality, food security, and aquatic biodiversity and sustainability. The goal of CyanoSCape is to utilize airborne hyperspectral data and field spectral and water sample data to distinguish phytoplankton biodiversity, including the potentially toxic cyanobacteria. mCDR: Marine Carbon Dioxide Removal The goals of this effort are to conduct literature review, analysis, and ocean simulation to provide scientifically vetted estimates of the impacts, risks, and benefits of various potential mCDR methods. Ocean modeling Atlantic Meridional Overturning Circulation (AMOC) in a changing climate The goals of this project are to build scientific understanding of the AMOC physics and its implications for biogeochemical cycles and climate, to assess the representation of AMOC in historical global ocean state estimates, and evaluate future needs for AMOC systems in a changing climate. Elucidating the role of the ocean circulation in changing North Atlantic Ocean nutrients and biological productivity This project will conduct analysis of NASA’s ECCO-Darwin ocean biogeochemical state estimate and historical satellite ocean color observations in order to understand the underlying causes for the sharp decline in biological productivity observed in the North Atlantic Ocean. Integrated GEOS and ECCO Earth system modeling and data assimilation to advance seasonal-to-decadal prediction through improved understanding and representation of air-sea interactions This analysis will build understanding of upper ocean, air-sea interaction, and climate processes by using data from the SWOT mission and ultra-high-resolution GEOS-ECCO simulations.

Notwithstanding its icy acronym, ICESat-2 can do more than measure ice – in fact, the expanded acronym hints at these wider applications. From vegetation to inland surface water to bathymetry, ICESat-2 has emerged as a more versatile mission than originally planned, thanks in part to the ingenuity of research scientists, the Science Team (ST), and users of the data – see Figure 1. Figure 1. A word cloud designed to highlight terms that occur most frequently in all ICESat-2 publications since 2018. The larger the word, the more often it is used.Figure credit: Aimee Neeley ICESat-2 was among the first NASA missions to develop an applications program that engages both scientists and potential users of the science data to accelerate user uptake. Throughout this program, ICESat-2 has demonstrated the value of Earth Observation data to end users, stakeholders, and decision makers. The ICESat-2 Early Adopter (EA; pre-launch) program, now the Applied User program (post-launch), was created to “promote applications research to provide a fundamental understanding of how ICESat-2 data products can be scaled and integrated into organizations, policy, business, and management activities to improve decision making efforts.” This article summarizes the workshop objectives met through plenary talks, lightning talks, an applied user panel, and a breakout session. The ICESat-2 Applications page contains more about the ICESat-2 Applications Program. Motivation and Objectives To meet Applications Program initiatives, the ICESat-2 Applications Team hosted its third Applications workshop June 3–4, 2024 at NASA’s Goddard Space Flight Center (GSFC) in a hybrid environment. A total of 113 participants registered for the workshop, representing multiple government agencies, including NASA Centers, non-profit organizations, and academic organizations – see Figure 2. Approximately 20 individuals attended the workshop in person with the majority participating online through the Webex platform. This workshop provided the space to foster collaboration and to encourage the conceptualization of applications not yet exploited. Figure 2. A ‘donut’ plot showing the proportion of ICESat-2 Applications Workshop attendees identified by institution. This information was provided during the online registration process.Figure credit: Aimee Neeley The objectives of the Applications workshop were to: provide an overview of the mission status, data products, and support services from the National Snow and Ice Data Center (NSIDC); build partnerships among applied users, data producers, and end users; foster synergies with all participants, decision makers, and satellite operators; identify new potential applications or products from ICESat-2; review available tools for extracting ICESat-2 data; and understand the challenges faced by applied users, data users, and end users, and identify solutions. The remainder of this article will summarize the meeting highlights. Rather than give a strict chronological survey, the report is organized around the meeting objectives listed above. Readers interested in more details can find the full agenda and slide decks from individual presentations mentioned in this summary on the ICESat-2 Workshop website. Workshop Overview and Structure The agenda of the 2024 ICESat-2 Applications workshop was intended to bring together end-users, including ICESat-2 applications developers, satellite operators, and decision makers from government and nongovernmental entities to discuss the current state and future needs of the community – see Figure 3. On the morning of the first day, the workshop participants contributed to a plenary session and ICESat-2 data tool demonstrations. These presentations were intended to provide a broad overview of the ICESat-2 mission, data, science, and applications. Plenary talks during the afternoon session provided an overview of the Earth Science-to-Action initiative and measuring impacts of science. The afternoon also included lightning talks from participants and an Applied User Panel. The second day consisted of a plenary presentation and more lightning talks from participants. The workshop ended with a thematic breakout session with pre-constructed topics and a report out to create a forum for direct interaction between participants. Figure 3.

Walter Meier [University of Colorado, Boulder (UC, Boulder)—NSIDC DAAC Scientist] provided an overview of ICESat-2 data tools and services. He walked the audience through the ICESat-2 data website, as well as the instructional guides that are available for all the tools and services. Meier provided an overview of ICESat-2 standard data products – see Figure 3. Most of the products have a ~45-day latency while quick look data sets have an ~3-day latency. Future data sets include ATL24 and ATL25 and quick look data sets for ATL03, ATL20, and ATL25. Next, he described webinars and tutorials, access tools, and customization services for different users and workflows, including graphical user interfaces and programmatic tools in Earthaccess and the NSIDC website. Helen Amanda Fricker [Scripps Institution of Oceanography, University of California (UC), San Diego—ICESat-2 ST Leader and Professor] provided an overview of the ST members and ST goals. Fricker described the ST goals to: 1) provide coordination between the team, project science office, and NASA headquarters; 2) use science talks, posters, and social events to stimulate collaboration within the ST and across disciplines; and 3) maintain the visibility of the ICESat-2 mission through publications, press releases, white papers, open science, and synergies with other missions. Next, Fricker shared the list of ST members that can be found on the ICESat-2 website. She concluded with an overview of a recent publication by Lori Magruder [University of Texas, Austin] and coauthors published in Nature Reviews. Stephanie Schollaert Uz [NASA GSFC—Applied Sciences Manager] provided an overview of the NASA Applied Science Program, including the current NASA Earth Science Satellite missions that are monitoring Earth systems. The NASA Applied Science Programs “tackle challenges on our home planet in areas for which Earth science information can respond to the urgent needs of our time.” Earth science data products are used to “inform decisions and actions on management, policy and business.” Uz provided examples of applications using Earth science data, including economic activity, active fire mapping, food security, and monitoring air quality – see Figure 4. Figure 4. Near real-time active fire mapping as well as air quality monitoring and forecasting are available via NASA’s Fire Information for Resource Management System (FIRMS).Figure credit: FIRMS U.S./Canada Molly E. Brown [University of Maryland—ICESat-2 Mission Applications Scientist] began her presentation by defining the term application in the context of this workshop, which includes “innovative uses of mission data products in decision-making activities for societal benefit.” Brown stated that the ICESat-2 Mission Applications program “works to bring our data products into areas where they can help inform policy or decisions that benefit the public.” End users include the private sector, academia, and government agencies. Brown described the benefits of the program and strategies to extend ICESat-2 to new communities – see Figure 5. Brown concluded with an overview of recent publications and new research efforts to assess the impact of ICESat-2 data. Figure 5. Strategies to extend ICESat-2 to new communities through activities and trainings such as those hosted by the Applied Remote Sensing Training (ARSET) program.Figure credit: Molly Brown Mike Jasinski [NASA GSFC, Hydrological Sciences Laboratory—Assistant Chief for Science] provided an overview of ICESat-2 inland water standard and quick look data products, ATL13QL and ATL22QL. ICESat-2 covers approximately one million lakes each year. Jasinski also listed application areas for water resources decision support, including river elevation and discharge, lake and reservoir water balance and management, and validation of Surface Water and Ocean Topography (SWOT) data. He provided metrics for each data product and quick look product and the advantages and disadvantages of ATL13 and ATL22 data products. Mary D. Ari [Centers for Disease Control and Prevention, Office of Science—Senior Advisor for Science] provided an overview of the Science Impact Framework (SIF). Ari explained that our partners and public need “evidence to support practice or policy or decision making, accountability for public finds, and research focus to advocate for research priority.” A major goal is to translate findings into practice or action. Next, she presented ways by which impact can be measured, including bibliometrics (quantitative) and value (qualitative). Ari further explained the Science Impact Framework (SIF), which includes five domains of scientific influence: disseminating science, creating awareness, catalyzing action, effecting change, and shaping the future – see Figure 6. Figure 6. The Science Impact Framework, which allows the impact of scientific work to be quantified and to determine if the science we produce is being put into action.Figure credit: Mary Ari Woody Turner [NASA Headquarters—ICESat-2 Program Applications Lead] provided an overview of NASA’s Earth Science to Action Strategy. Turner explained that NASA’s Earth Science to Action strategy is integral to the Earth Science Division’s 2024–2034 strategic plan. The overall strategy has two objectives: 1) observe, monitor, and understand the Earth System and 2) deliver trusted information to drive Earth resilience activities. He also summarized the “three key pillars” for this new Earth Action paradigm to 1) be user centered, 2) build bridges between research, technology, flight, data, and Earth Action elements, and 3) scale up existing efforts to get NASA data into the hands of end users. Lastly, Turner listed NASA’s core values, including safety, integrity, inclusion, teamwork, excellence, trustworthiness, innovation, and collaboration. Objective 2: Review available tools for extracting ICESat-2 data for a diverse community. To achieve this objective, the meeting included a series of presentations in which each speaker described a different tool that is being used to download and analyze ICESat-2 data. Jessica Scheick [University of New Hampshire] provided an overview of a set of Python tools, named icepyx, that can be used to obtain and manipulate ICESat-2 data. Scheick, who developed icepyx, described how the tools address challenges with ICESat-2 data. Lastly, she performed a live demonstration of icepyx. Tyler Sutterley [Applied Physics Laboratory/University of Washington] presented a live demonstration of Sliderule, an ICESat-2 plugin module that uses an application programming interface (API) to “query a set of ATL03 input granules for photon heights and locations based on a set of photon-input parameters that select the geographic and temporal extent of the request.” Joanna D. Millstein [Colorado School of Mines] provided an overview of CryoCloud, which is a “JupyterHub built for NASA cryosphere communities in collaboration with 2i2c.” The goal of CryoCloud is to create a “simple and cost-effective managed cloud environment for training and transitioning new users to cloud workflows and determining community best practices.” CryoCloud makes it possible to “process data faster, minimize downloading and democratize science.” The CryoCloud GitHub provides access to a Slack channel, trainings and tutorials, and community office hours. Mikala Beig [UC, Boulder—NSIDC User Services] provided and overview of OpenAltimetry, a platform for visualizing and downloading surface elevation data from ICESat and ICESat-2. OpenAltimetry was developed to alleviate the challenges faced by researchers, including the “steep learning curves and heavy demands on computational resources” necessary to download and manipulate large volumes of data. The strengths of OpenAltimetry include fostering user engagement, lowering technical hurdles for visualizing data, and allowing deeper data exploration. Lastly, Beig demonstrated the platform for the audience – see Figure 7. Figure 7. Searching ICESat-2 tracks in OpenAltimetry, a map-based data visualization and discovery tool for altimetry data.Figure credit: Mikala Beig Objectives 3 and 4: Foster synergies between all participants; Identify new potential applications or products from ATLAS data not currently under investigation. To meet these two meeting objectives, workshop organizers scheduled a round of lightning talks, where a series of presenters gave five-minute presentations on their research or activities. The talks are distilled below. The reader is directed online to find formal presentation titles and additional information. There was also an applied user panel and a breakout session to facilitate synergies between participants and identify new applications. Younghyun Koo [Lehigh University/ Cooperative Institute for Research in Environmental Science (CIRES)] described a method to filter landfast ice (or sea ice “fastened” to the coastline) for accurate examination of thermodynamic and dynamic sea ice features using the ICESat-2 ATL10 data product – see Figure 8. Chandana Gangodagamage [OeilSat—Principal Investigator] described the company’s efforts to track freshwater in the Congo River for the purposes of water resources management and other water-related applications that require river bathymetry data. Daniel Scherer [Technischen Universität München (TUM), Germany] provided an overview of the ICESat-2 River Surface Slope (IRIS), a global reach-scale water surface slope dataset that provides average and extreme water slopes from ICESat-2 observations. The data can be dowloaded from Zenodo. Louise Croneborg-Jones [Water In Sight—Chief Executive Officer] described her company’s effort to use satellite data and mobile and cloud technology to digitize river and rainfall observation at scale in Malawi. Water In Sight has emphasized getting local communities involved in monitoring water resources to increase observations of water levels for conservation. Ravindra Duddu [Vanderbilt University] provided an overview on a project called Modeling Antarctic Iceshelf Calving and Stability (MAGICS), which involves using computation, data, and machine learning to map the rift and crevasse configurations of ice shelves in Antarctica to better understand calving events. Shawn Serbin [GSFC] discussed use of harmonized above ground products from ICESat-2 and other earth observing platforms, including Global Ecosystem Dynamics Investigation (GEDI), Soil Moisture Active Passive (SMAP), and Moderate Resolution Imaging Spectroradiometer (MODIS), for terrestrial ecosystem carbon cycle reanalysis and near-term, iterative forecasting for North America and the globe. Wengi Ni-Meister [Hunter College of the City University of New York—ICESat-2 Early Adopter] summarized an effort to retrieve canopy and background reflectivity ratio from ICESat-2 data and use it for the retrieval of vegetation cover and snow distribution in boreal forests. Morgaine McKibben [GSFC–Plankton, Aerosol, Clouds, ocean Ecosystem (PACE) Applications Lead] provided an overview of NASA’s PACE mission, suggesting possible synergies between ICESat-2 and PACE with the intent of opening the door for further discussion on collaboration between the two missions. (To learn more about planned applications for PACE, see Preparing for Launch and Assessing User Readiness: The 2023 PACE Applications Workshop. (Also published in The Earth Observer, Nov–Dec 2023, 35:6, 25–32.) Anthony Campbell [GSFC/ University of Maryland, Baltimore County] discussed his group’s research into using ICESat-2 data to monitor changes in coastal wetland migration, including coastal elevation and canopy height. Brian A Campbell [NASA’s Wallops Flight Facility (WFF)—ICESat-2 Mission Education Lead] described the Global Learning and Observations to Benefit the Environment (GLOBE) program’s network of citizen scientists who collect several different kinds of data using the GLOBE Observer app. He highlighted one data type with particular relevance to ICESat-2. GLOBE Trees – see Figure 8 – equips citizen scientists with the tools to take tree height measurements using their mobile devices. These observations could then be compared to data from NASA satellite missions. Figure 8. NASA’s Global Learning and Observations to Benefit the Environment (GLOBE) has developed an app called GLOBE Trees that allows users take measurements of tree height data using a mobile device. Those data can then be uploaded, and scientists can use them to validate satellite tree height measurement (e.g., from ICESat-2/ATLAS).Figure credit: Brian Campbell Caio Hamamura [University of Florida/School of Forest, Fisheries & Geomatics Sciences—Postdoctoral Associate] summarized a literature review his team had conducted of studies using ICESat-2 data for land and vegetation applications as well as results of an assessment of the current capability and limitations of ICESat-2 data for land and vegetation applications – see Figure 9. Figure 9. Illustration of the ATL18 canopy height product at 1 km (~0.6 mi) spatial resolution at the global scale. The height values represent the median of all ATL18 height estimates within a given grid size of 1 km.Figure credit: Jordan Borak and Ciao Hamamura Jacob Comer [Cultural Site Research and Management Foundation] summarized results from an evaluation of the use of ICESat-2 data for archaeological prospection and documentation of archaeological sites – particularly in the Federal States of Micronesia. Juradana M. Iqrah [University of Texas at San Antonio] described her group’s effort to obtain high resolution sea ice classification and freeboard information from ICESat-2 ATL03 observations to understand the impact of global warming on the melting and retreat of polar sea ice cover. Michael MacFerrin [National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI)—Coastal Digital Elevation (DEM) Model Team] provided an overview of the NOAA/CIRES ICESat-2 Validation of Elevations Reporting Tool (IVERT) tool, which is used to generate land-based validation statistics of digital elevation models (DEM) anywhere in the word using the ATL03 and ATL08 datasets – see Figure 10. Figure 10. Digital Elevation Model output before and after Hurricane Michael in Florida, October 2018.Figure credit: Michael MacFerrin Gretchen Imahori [NOAA National Geodetic Survey, Remote Sensing Division] presented an overview of satellite derived bathymetry using ICESat-2 data, including the new Level 3 (L3) bathymetry data product (ATL24) that will be available later in 2024 – see Figure 11. Figure 11. Bathymetry data from ICESat-2 have been used across a wide variety of morphologies [some of which are illustrated in the photos above] and disciplines. Figure credit: Gretchen Imahori and the ICESat-2 bathymetry working group Objectives 5 and 6: Understand the challenges faced by applied, data users, and end users and identify solutions. Build partnerships between applied users, data producers, and end users. To achieve these two objectives, planners organized an applied user panel and a breakout session as means to foster conversation among participants. The applied user panel consisted of five panelists– three participating virtually and two in-person. The presenters in the session shared their responses to three prepared discussion prompts: 1) an introduction of ICESat-2 data products; 2) use of ICESat-2 data products for their application; and 3) potential data latency impacts. The conversation was brief, but it provided a unique opportunity to hear from experienced applied users. A breakout session consisted of pre-planned discussion prompts through two virtual breakout groups and one in-person group. Group One discussed questions that covered examination of ice crevassing and rifting, community tools for shallow water mapping, and slope measurement bias and uncertainties. Group Two discussed a variety of current and potential surface water applications, identified challenges using ICEat-2 data, and developed suggestions to increase the accessibility and usability of ICESat-2 data products. Group Three covered a gamut of topics, including potential products for Alaskan and Canadian communities, increased accessibility to products, and applications through central cloud storage systems, central repositories and detailed documentation, and the desire for future topic-specific workshops and focus sessions. Conclusion The 2024 NASA ICESat-2 Applications Workshop was the third in a series of workshops – with the first workshop occurring in 2012, six years prior to launch. The EA program was transitioned to the Applied User program, which deployed a post-launch program per the NASA Early Adopter Handbook “that acts as a continuation of the Early Adopter program to engage with Communities of Practice and Potential.” This workshop provided the space to foster collaboration and conceptualization of applications not yet exploited that may be developed using ICESat-2 data products. The workshop met its objectives and created an environment that fostered collaboration between participants. The workshop was a success, and participants requested another one focused on a thematic topic. Updates, future workshops, and other events will be posted on the ICESat-2 ‘Get Involved’ page.

Mission scientists were particularly intrigued to investigate several bright-toned rocks (at the middle-right, bottom-right and bottom-center of the image), similar to rocks that Curiosity had encountered previously that were unexpectedly rich in sulfur. This image was taken by Left Navigation Camera aboard Curiosity on Sol 4306 — Martian day 4,306 of the Mars Science Laboratory Mission — on Sept. 16, 2024 at 12:47:18 UTC. NASA/JPL-Caltech Earth planning date: Monday, Sept. 16, 2024 We made good progress through Gediz Vallis in the weekend drive, landing in a segment of the channel containing a mix of loose rubble and other channel-filling debris. Amongst the jumbled scene, though, particular objects of interest caught our eye: bright rocks. In past workspaces in Gediz Vallis, similar bright rocks have been associated with very high to almost pure sulfur contents. As all good geologists know, however, color is not diagnostic, so we cannot assume these are the same as sulfur-rich rocks we have encountered previously. The only way to know is to collect data, and that was a significant focus of today’s plan. We planned multiple mosaics across the examples of bright rocks visible in the image above. Mastcam and ChemCam RMI will cover “Bright Dot Lake” and “Sheep Creek” both in the right midfield of the image. Mastcam imaged the example in the bottom right corner of the image at “Marble Falls,” and ChemCam LIBS targeted one of the small bright fragments along the bottom of the image at “Blanc Lake.” There was also a small bit of bright material in the workspace, but unfortunately, it was not reachable by APXS. APXS analyzed a spot near the bright material, at target “Frog Lake,” and MAHLI was able to tack on a few extra images around that target that should capture the bright material. MAHLI also imaged a vuggy target in the workspace at “Grasshopper Flat.” The wider context of the channel was also of interest for imaging, so we captured the full expanse of the channel with one Mastcam mosaic, and focused another on mounds distributed through the channel at target “Copper Creek.” Even with all this rock imaging, we did not miss a beat with our environmental monitoring. We planned regular RAD, REMS, and DAN measurements, mid and late day atmospheric dust observations, a cloud movie, and dust devil imaging. Our drive is planned to take us up onto one of the ridges in the channel. Will we find more bright rocks there? Or something new and unexpected that was delivered down Gediz Vallis by some past Martian flood or debris flow? Only the channel knows!

Technicians work to complete operations before propellant load occurs ahead of launch for NASA’s Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida on Tuesday, Sept. 11, 2024. NASA/Kim Shiflett NASA’s Europa Clipper mission moves closer to launch as technicians worked on Wednesday, Sept. 11, inside the Payload Hazardous Servicing Facility to prepare the spacecraft for upcoming propellant loading at the agency’s Kennedy Space Center in Florida. The spacecraft will explore Jupiter’s icy moon Europa, which is considered one of the most promising habitable environments in the solar system. The mission will research whether Europa’s subsurface ocean could hold the conditions necessary for life. Europa could have all the “ingredients” for life as we know it: water, organics, and chemical energy. Europa Clipper’s launch period opens on Thursday, Oct. 10. It will lift off on a SpaceX Falcon Heavy rocket from Kennedy’s Launch Complex 39A. The spacecraft then will embark on a journey of nearly six years and 1.8 billion miles before reaching Jupiter’s orbit in 2030. The spacecraft is designed to study Europa’s icy shell, underlying ocean, and potential plumes of water vapor using a gravity science experiment alongside a suite of nine instruments including cameras, spectrometers, a magnetometer, and ice-penetrating radar. The data Europa Clipper collects could improve our understanding of the potential for life elsewhere in the solar system. Photo credit: NASA/Kim Shiflett View the full article

Figure credit: NASA Prior to the event, Trena Ferrell [GSFC—Earth Science Education and Public Outreach Lead] arranged for groups of students from several local schools to visit the NASA Earth Day event. This included over 300 students from DuVal High School, Morgan State University, Howard University, Prince George’s County Environmental Academy, Prince George’s County Virtual Academy, International Hispanic School, and homeschoolers. On April 19, all of the students who were present at that time gathered for a plenary in the Webb Auditorium. Ferrell welcomed the attendees and provided introductions to prepare them for a virtual presentation by former NASA astronaut Paul Richards, who interacted with attendees and answered questions for roughly 20 minutes. After Richard’s presentation, the attendees heard from Karen St. Germain [NASA HQ—Director of NASA’s Earth Science Division], whose in-person remarks emphasized to the students the crucial albeit less publicized studies that NASA does of our home planet. Related to this year’s Earth Day theme, “Water Touches Everything,” she discussed the ability of NASA’s Earth observing satellites to track water in all its forms as it circulates throughout the Earth system. St. Germain then answered questions from the audience for 15 minutes – see Photos 5–8.

Photo credit: NASA Conclusion NASA’s first Earth Day Celebration at NASA Headquarters was quite successful. While attendance was lower than previous events held at the more heavily trafficked Union Station or the National Mall, there was a steady stream of people throughout the exhibit on both days. It was also a great opportunity to showcase the new EIC to the public. Earth Day is the largest event organized annually by the SSO. This event requires months of planning, cross-divisional coordination, and intensive design of the hands-on activities – all carried from conceptualization through numerous revisions to implementation by more than 100 individuals from across the agency. This combined effort of SSO staff and assisting organizations results in an event that brings together thousands of visitors from a broad spectrum of ages and backgrounds to enjoy NASA science. This event would not have been possible were it not for the incredible efforts and collaboration put forth by so many of NASA’s outreach professionals. The SSO is grateful for all who helped to make this year’s Earth Day event a success and looks forward to Earth Day 2025.

This enormous piece of space hardware is NASA’s Nancy Grace Roman Space Telescope’s spacecraft bus, which will maneuver the observatory to its place in space and enable it to function while there. It is photographed here in the largest clean room at NASA’s Goddard Space Flight Center, where engineers are inspecting it upon delivery. The bus rests atop an aluminum ring that will temporarily protect its underside. The two copper-colored flaps are Roman’s Lower Instrument Sun Shade –– deployable panels designed to help shield the observatory from sunlight.NASA/Chris Gunn The spacecraft bus that will deliver NASA’s Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing. Now that the spacecraft is assembled, engineers will begin working to integrate the observatory’s other major components, including the science instruments and the telescope itself. “They call it a spacecraft bus for a reason — it gets the telescope to where it needs to be in space,” said Jackie Townsend, the Roman deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But it’s really more like an RV because it has a whole assortment of functions that enable Roman to accomplish its scientific goals while out there too.” Those goals include surveying wide swaths of the universe to study things like: dark energy, a mysterious cosmic pressure thought to accelerate the universe’s expansion; dark matter, invisible matter seen only via its gravitational influence; and exoplanets, worlds beyond our solar system. The mission’s science wouldn’t be possible without a spacecraft to transport the telescope, point the observatory toward different cosmic targets, provide power, communicate with Earth, control and store instrument data, and regulate Roman’s temperature. Nearly 50 miles of electrical cabling are laced throughout the assembly to enable different parts of the observatory to communicate with each other. The spacecraft will also deploy several major elements that will be stowed for launch, including the solar panels, deployable aperture cover, lower instrument Sun shade, and high-gain antenna. It’s also responsible for collecting and beaming down data, which is no small task for a space observatory that will survey the cosmos like Roman will. “Roman will send back 1.4 terabytes of data per day, compared to about 50 to 60 gigabytes from the James Webb Space Telescope and three gigabytes from the Hubble Space Telescope,” said Jason Hylan, the Roman observatory manager at NASA Goddard. “Webb’s daily downlink is roughly comparable to 13 hours of YouTube video at the highest quality while Roman’s would amount to about 2 weeks.” This top-down view shows NASA’s Nancy Grace Roman Space Telescope’s spacecraft bus from another angle. It rests atop an aluminum ring that will not be part of the observatory and is surrounded by an enclosure used in testing to ensure electromagnetic interference will not affect the bus’s sensitive electronics. The bus is covered in gray bagging material to prevent contamination –– even tiny stray particles could affect its performance.NASA/Chris Gunn A Goddard Grand Slam This milestone is the culmination of eight years of spacecraft design work, building, and testing by hundreds of people at Goddard. “Goddard employees were the brains, designers, and executors. And they worked with vendors who supplied all the right parts,” Townsend said. “We leaned on generations of expertise in the spacecraft arena to work around cost and schedule challenges that arose from supply chain issues and the pandemic.” One time- and money-saving technique the team came up with was building a spacecraft mockup, called the structural verification unit. That allowed them to do two things at once: complete strength testing on the mockup, designed specifically for that purpose, while also assembling the actual spacecraft. The spacecraft’s clever layout also allowed the team to adapt to changing schedules. It’s designed to be modular, “more like Trivial Pursuit pie pieces than a nesting egg, where interior components are buried inside,” Townsend said. “That’s been a game-changer because you can’t always count on things arriving in the order you planned or working perfectly right away with no tweaks.” It also increased efficiency because people could work on different portions of the bus at the same time without interfering with each other. The slightly asymmetrical and hexagonal spacecraft bus is about 13 feet (4 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms). While it may look small in this photo, the spacecraft bus for NASA’s Nancy Grace Roman Space Telescope is 8 feet (2.5 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms). In this photo, it rests atop an aluminum ring that will not be part of the observatory. The bundles of wires on top are part of more than 50 miles of cabling laced throughout the assembly to enable different parts of the observatory to communicate with each other.NASA/Chris Gunn One reason it doesn’t weigh more is that some components have been partially hollowed out. If you could peel back some of the spacecraft’s panels, you’d find superthin metallic honeycomb sandwiched between two slim layers of metal. And many of the components, such as the antenna dish, are made of strong yet lightweight composite materials. When the spacecraft bus was fully assembled, engineers conducted a comprehensive performance test. Prior to this, each component had been tested individually, but just like with a sports team, the whole unit has to perform well together. “The spacecraft passed the test, and now we’re getting ready to install the payload –– Roman’s instruments and the telescope itself,” said Missie Vess, a spacecraft systems engineer for Roman at NASA Goddard. “Next year, we’ll test these systems together and begin integrating the final components of the observatory, including the deployable aperture cover, outer barrel assembly, and solar panels. Then we’ll finally have ourselves a complete observatory, on track for launch by May 2027.” To virtually tour an interactive version of the telescope, visit: https://roman.gsfc.nasa.gov/interactive The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions.

News Chief Rob Garner shares NASA Goddard’s story with the public, supporting writers and creators in the Office of Communications. Name: Rob Garner Title: News Chief Formal Job Classification: Senior public affairs specialist Organization: Office of Communications (Code 130) Rob Garner has worked in the Office of Communications at NASA’s Goddard Space Flight Center in Greenbelt, Md., since 2007.NASA/Jamie Adkins What do you do and what is most interesting about your role here at Goddard? I am responsible for helping take the great work going on at our center and sharing it with as many people as we can. My job is sort of like being an editor in chief. I try to set the tone for our storytelling and manage our publication schedule. Mostly I try to give our writers and other communicators the support they need to do their jobs — and then I try to get out of their way so they can do what they do best. What is your educational background? I have a B.A. in journalism from the University of Maryland, College Park, with a minor in astronomy, as well as a Master of Library Science degree focusing on archives, also from UMD. Why did you want to be a journalist? I sort of fell into the work that I am doing. In high school, I thought I would be a band director. I realized very quickly after high school that my enthusiasm for music did not align with my proficiency in it. Music remains an important hobby, but I needed to make a living doing something else. I did not really enjoy writing until I got to college and had the opportunity to experience journalism. Tight writing, going straight to the source to get answers, accurate researching, it all appealed to me. I think journalism as a profession plays a critical role in ensuring an informed and functional society. How did you come to work for Goddard? After I graduated college, I worked weekends for a few months on the digital desk at WTOP radio, editing copy and updating their website. I was still looking for a fulltime gig, and I happened upon a newspaper classified for a position at Goddard. It called for a little bit of newswriting, a little bit of web editing, a little bit of science. Until that moment, I never imagined NASA could have a place for someone like me. Goddard offered me a one-year fellowship in the Office of Communication (back then called Public Affairs) to do website editing for our Earth science team. The fellowship was renewed a few times, and eventually I became a general web editor, then also a social media editor, and eventually leader of the digital media team. In 2022, I became the news chief. As news chief, what is your vision? I take very seriously the part of NASA’s 1958 charter that charges the agency not just with conducting cutting-edge research, but also with sharing our work with the broadest possible audience. We must also drive home why what we do matters. The first thing I look for when reviewing copy is how well the piece addresses the “why.” What makes a good science communicator? Goddard has some 10,000 people, mostly researchers and engineers. Here, a successful science communicator is one who develops relationships among these different people and a deep understanding of their many projects. As communicators, we cannot do our jobs if we do not also have the trust of the people actually doing the science. As a mentor, what is the one big piece of advice you give? I tell our interns to jump in with both feet. So much of what we do and what we know cannot be found in any handbook or manual. So much of it is the institutional knowledge that each of us carries based on our own experiences. Grab hold of the people who have the experience and take in as much as you can from them. Immersing in and embracing that Goddard culture is what will set apart a good colleague from a great one. Everyone in the newsroom here knows that you are quite fond of the Associated Press (AP) Stylebook and the NASA Stylebook and Communications Manual. Can you please explain what they and why you are so fond of them? One can think of AP style as an appendix or addendum to the dictionary, and the NASA style manual as an appendix or addendum to AP. The aim in having all of these mechanics standardized is to make it easier for the reader to read what you are writing. Even if one doesn’t know the rules governing serial comma usage, most of us can tell when what we’re reading is sloppy. Any time you force the reader to pause and review, there is a chance you will lose them. They may tune out and take their attention elsewhere. These manuals lay out more than the mechanics of which states get abbreviated in what way, when to use semicolons, and when to use em dashes. They also give us guidelines about how to do our jobs, covering things like ethics, chain of command, and conflict resolution. What do you enjoy best about your job? My job is not just editing copy, fielding questions from reporters, or escorting groups for tours or documentary filming. I do enjoy all of that, but what I like most is that every day is different, and every day I learn something new. I love the variety of tasks and tactics that we use get our message out to the world. NASA plays a critical role in benefitting all of humanity by broadening our knowledge about the universe and our place in it. It’s personally very meaningful to me to have even a small role in that mission. And I enjoy working with a really great group of people. You said in high school you thought you would become a band director. Have you kept up with playing? In my free time, I do still play trumpet. For almost 20 years, I have played in community orchestras that draw repertoire from video game soundtracks. The past 10 years, I’ve been with the Washington Metropolitan Gamer Symphony Orchestra (WMGSO), along with my wife, who plays the violin. This group — well over 100 of us — originated when we were all in college, and we have continued together since then. What makes our group special is that we still do a lot of the orchestration ourselves, meaning that you cannot hear our music anywhere else. We meet once a week and perform three or four times a year throughout the D.C. area. We even have an album out, with another on the way soon. Can you please tell us about your dog rescue volunteer work? Since 2018, my wife and I have been involved with a couple area animal rescues. We typically take in newly weaned puppies and keep them for the weeks or months it takes for them to find their forever homes. While they are in our care, we keep them safe, fed, warm, and loved. We also socialize them as much as possible. The organizations take care of finding them homes through weekly adoption events. My wife and I have three dogs of our own, two of which are rescues from this group. We have fostered hundreds over the years. I lost count somewhere north of 250 — and counting. I think it is important for everyone to find a way to make the world a better place. This is our way of doing that. Garner and then-Goddard News Chief Ed Campion celebrating the latter’s retirement in 2018. Aloha shirt Fridays were a mainstay of Campion’s tenure.NASA/Bill Hrybyk Who would you like to thank for helping you? That’s a long list! I’m forever grateful to Goddard’s executive producer, Wade Sisler, who saw something in babyface Rob Garner, nearly fresh out of school, and gave me a chance at a toehold in NASA. I definitely want to thank Ed Campion, our retired former news chief and “minister of truth,” for all he did for me. When I first got to Goddard in 2007, Ed was one of the first people to take me under his wing and teach me about Goddard and NASA culture. Ed came through the agency during some very hard times, both shuttle accidents, and some very important highs, like the successful Hubble telescope repair missions. He worked at NASA Headquarters in Washington and also at Johnson Space Center in Houston. I learned a lot about how to do this job, and how to treat your teammates, from him. I also want to thank my wife Katie. She’s challenged me and encouraged me to grow into a better person. Raising a family together has been a wild ride, and it’s only just getting started. What is your “six-word memoir”? A six-word memoir describes something in just six words. “Omit needless words. Assume positive intent.” The first half was the rule hammered into us in journalism school. The second half is the mantra I learned from Michelle Jones, former head of Goddard communications, about treating others with kindness and compassion. Michelle — now the deputy associate administrator for communications at NASA — is another mentor I could never thank enough for helping me get where I am. By Elizabeth M.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This artist’s concept depicts NASA’s Europa Clipper spacecraft in orbit around Jupiter. The mission is targeting an Oct. 10, 2024, launch.NASA/JPL-Caltech The first NASA spacecraft dedicated to studying an ocean world beyond Earth, Europa Clipper aims to find out if the ice-encased moon Europa could be habitable. NASA’s Europa Clipper spacecraft, the largest the agency has ever built for a planetary mission, will travel 1.8 billion miles (2.9 billion kilometers) from the agency’s Kennedy Space Center in Florida to Europa, an intriguing icy moon of Jupiter. The spacecraft’s launch period opens Thursday, Oct. 10. Learn more about how NASA’s Europa Clipper came together – and how it will explore an ocean moon of Jupiter. Credit: NASA/JPL-Caltech Data from previous NASA missions has provided scientists with strong evidence that an enormous salty ocean lies underneath the frozen surface of the moon. Europa Clipper will orbit Jupiter and conduct 49 close flybys of the moon to gather data needed to determine whether there are places below its thick frozen crust that could support life. Here are eight things to know about the mission: 1. Europa is one of the most promising places to look for currently habitable conditions beyond Earth. There’s scientific evidence that the ingredients for life — water, the right chemistry, and energy — may exist at Europa right now. This mission will gather the information scientists need to find out for sure. The moon may hold an internal ocean with twice the water of Earth’s oceans combined, and it may also host organic compounds and energy sources under its surface. If the mission determines that Europa is habitable, it would mean there may be more habitable worlds in our solar system and beyond than we have imagined. 2. The spacecraft will fly through one of the most punishing radiation environments in our solar system — second only to the Sun’s. Jupiter is surrounded by a gigantic magnetic field 20,000 times stronger than Earth’s. As the field spins, it captures and accelerates charged particles, creating radiation that can damage spacecraft. Mission engineers designed a spacecraft vault to shield sensitive electronics from radiation, and they plotted orbits that will limit the time Europa Clipper spends in most radiation-heavy areas around Jupiter. 3. Europa Clipper will orbit Jupiter, studying Europa while flying by the moon dozens of times. The spacecraft will make looping orbits around Jupiter that bring it close to Europa for 49 science-dedicated flybys. On each orbit, the spacecraft will spend less than a day in Jupiter’s dangerous radiation zone near Europa before zipping back out. Two to three weeks later, it will repeat the process, making another flyby. 4. Europa Clipper features NASA’s most sophisticated suite of science instruments yet. To determine if Europa is habitable, Europa Clipper must assess the moon’s interior, composition, and geology. The spacecraft carries nine science instruments and a gravity experiment that uses the telecommunications system. In order to obtain the best science during each flyby, all the science instruments will operate simultaneously on every pass. Scientists will then layer the data together to paint a full picture of the moon. 5. With antennas and solar arrays fully deployed, Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission. The spacecraft extends 100 feet (30.5 meters) from one end to the other and about 58 feet (17.6 meters) across. That’s bigger than a basketball court, thanks in large part to the solar arrays, which need to be huge so they can collect enough sunlight while near Jupiter to power the instruments, electronics, and other subsystems. 6. It’s a long journey to Jupiter. Jupiter is on average some 480 million miles (about 770 million kilometers) from Earth; both planets are in motion, and a spacecraft can carry only a limited amount of fuel. Mission planners are sending Europa Clipper past Mars and then Earth, using the planets’ gravity as a slingshot to add speed to the spacecraft’s trek. After journeying about 1.8 billion miles (2.9 billion kilometers) over 5½ years, the spacecraft will fire its engines to enter orbit around Jupiter in 2030. 7. Institutions across the U.S. and Europe have contributed to Europa Clipper. Currently, about a thousand people work on the mission, including more than 220 scientists from both the U.S. and Europe. Since the mission was officially approved in 2015, more than 4,000 people have contributed to Europa Clipper, including teams who work for contractors and subcontractors. 8. More than 2.6 million of us are riding along with the spacecraft, bringing greetings from one water world to another. As part of a mission campaign called “Message in a Bottle,” the spacecraft is carrying a poem by U.S. Poet Laureate Ada Limón, cosigned by millions of people from nearly every country in the world. Their names have been stenciled onto a microchip attached to a tantalum metal plate that seals the spacecraft’s electronics vault. The plate also features waveforms of people saying the word “water” in over 100 spoken languages. More About Europa Clipper Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet. Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NASA’s Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.

The image required 800 exposures taken over 400 Hubble orbits around Earth. The total amount of exposure time was 11.3 days, taken between Sept. 24, 2003 and Jan. 16, 2004. Credits: NASA, ESA, S. Beckwith (STScI) and the HUDF Team With the help of NASA’s Hubble Space Telescope, an international team of researchers led by scientists in the Department of Astronomy at Stockholm University has found more black holes in the early universe than has previously been reported. The new result can help scientists understand how supermassive black holes were created. Currently, scientists do not have a complete picture of how the first black holes formed not long after the big bang. It is known that supermassive black holes, that can weigh more than a billion suns, exist at the center of several galaxies less than a billion years after the big bang. “Many of these objects seem to be more massive than we originally thought they could be at such early times — either they formed very massive or they grew extremely quickly,” said Alice Young, a PhD student from Stockholm University and co-author of the study published in The Astrophysical Journal Letters. This is a new image of the Hubble Ultra Deep Field. The first deep imaging of the field was done with Hubble in 2004. The same survey field was observed again by Hubble several years later, and was then reimaged in 2023. By comparing Hubble Wide Field Camera 3 near-infrared exposures taken in 2009, 2012, and 2023, astronomers found evidence for flickering supermassive black holes in the hearts of early galaxies. One example is seen as a bright object in the inset. Some supermassive black holes do not swallow surrounding material constantly, but in fits and bursts, making their brightness flicker. This can be detected by comparing Hubble Ultra Deep Field frames taken at different epochs. The survey found more black holes than predicted.

Beckwith (UC Berkeley), Garth Illingworth (UC Santa Cruz), Richard Ellis (UCL); Image Processing: Joseph DePasquale (STScI) Download this image Black holes play an important role in the lifecycle of all galaxies, but there are major uncertainties in our understanding of how galaxies evolve. In order to gain a complete picture of the link between galaxy and black hole evolution, the researchers used Hubble to survey how many black holes exist among a population of faint galaxies when the universe was just a few percent of its current age. Initial observations of the survey region were re-photographed by Hubble after several years. This allowed the team to measure variations in the brightness of galaxies. These variations are a telltale sign of black holes. The team identified more black holes than previously found by other methods. The new observational results suggest that some black holes likely formed by the collapse of massive, pristine stars during the first billion years of cosmic time. These types of stars can only exist at very early times in the universe, because later-generation stars are polluted by the remnants of stars that have already lived and died. Other alternatives for black hole formation include collapsing gas clouds, mergers of stars in massive clusters, and “primordial” black holes that formed (by physically speculative mechanisms) in the first few seconds after the big bang. With this new information about black hole formation, more accurate models of galaxy formation can be constructed. “The formation mechanism of early black holes is an important part of the puzzle of galaxy evolution,” said Matthew Hayes from the Department of Astronomy at Stockholm University and lead author of the study. “Together with models for how black holes grow, galaxy evolution calculations can now be placed on a more physically motivated footing, with an accurate scheme for how black holes came into existence from collapsing massive stars.” Image Before/After Astronomers are also making observations with NASA’s James Webb Space Telescope to search for galactic black holes that formed soon after the big bang, to understand how massive they were and where they were located. 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.

Figure 1. An artist’s concept of the Van Allen belts with a cutaway section of the giant donuts of radiation that surround Earth. Image Credit: NASA Goddard Space Flight Center/Scientific Visualization Studio A new instrument is using advanced detection techniques and leveraging an orbit with specific characteristics to increase our understanding of the Van Allen belts—regions surrounding Earth that contain energetic particles that can endanger both robotic and human space missions. Recently, the instrument provided a unique view of changes to this region that were brought on by an intense magnetic storm in May 2024. The discovery of the Van Allen radiation belts by the U.S. Explorer 1 mission in 1958 marked a prominent milestone in space physics and demonstrated that Earth’s magnetosphere efficiently accelerates and traps energetic particles. The inner belt contains protons in the MeV (million electric volt) to GeV (109 electric volt) range, and even higher concentrations of energetic electrons of 100s of keV (1000 electric volt) to MeV are found in both the inner belt and the outer belt. The energetic electrons in these belts—also referred to as “killer electrons”—can have detrimental effects on spacecraft subsystems and are harmful to astronauts performing extravehicular activities. Understanding the source, loss, and varying concentrations of these electrons has been a longstanding research objective. High-energy resolution and clean measurements of these energetic electrons in space are required to further our understanding of their properties and enable more reliable prediction of their intensity. Overcoming the challenges of measuring relativistic electrons in the inner belt Measuring energetic electrons cleanly and accurately has been a challenge, especially in the inner belt, where MeV to GeV energy protons also exist. NASA’s Van Allen Probes, which operated from 2012 to 2019 in low inclination, geo-transfer-like orbits, showed that instruments traversing the heart of the inner radiation belt are subject to penetration by the highly energetic protons located in that region. The Relativistic Electron Proton Telescope (REPT) and the Magnetic Electron and Ion Spectrometer (MagEIS) instruments onboard the Van Allen Probes were heavily shielded but were still subject to inner-belt proton contamination. To attempt to minimize these negative effects, a University of Colorado Boulder team led by Dr. Xinlin Li, designed the Relativistic Electron Proton Telescope integrated little experiment (REPTile)—a simplified and miniaturized version of REPT—to fly onboard the Colorado Student Space Weather Experiment (CSSWE). An effort supported by the National Science Foundation, the 3-Unit CSSWE CubeSat operated in a highly inclined low Earth orbit (LEO) from 2012 to 2014. In this highly inclined orbit, the spacecraft and the instruments it carried were only exposed to the inner-belt protons in the South Atlantic Anomaly (SAA) region where the Earth’s magnetic field is weaker, which greatly reduced the time that protons impacted the measurement of electrons. REPTile’s success motivated a team, also led by Dr. Xinlin Li, to design REPTile-2—an advanced version of REPTile—to be hosted on the Colorado Inner Radiation Belt Experiment (CIRBE) mission. Like CSSWE, CIRBE operates in a highly inclined low-Earth orbit to ensure the exposure to damaging inner-belt protons is minimized. The team based the REPTile-2 design on REPTile but incorporated two additional technologies—guard rings and Pulse Height Analysis—to enable clean, high-energy-resolution measurements of energetic electrons, especially in the inner belt. Figure 2: PI observing two engineers testing the interface between the CIRBE bus and REPTile-2 on September 29, 2021. Image Credit: Xinlin Li, University of Colorado Boulder As shown on the left in Figure 3, the field of view (FOV) of REPTile-2 is 51o. Electrons and protons enter the FOV and are measured when they reach a stack of silicon detectors where they deposit their energies. However, very energetic protons (energy greater than 60 MeV) could penetrate through the instrument’s tungsten and aluminum shielding and masquerade as valid particles, thus contaminating the intended measurements. To mitigate this contamination, the team designed guard rings that surround each detector. These guard rings are electronically separated from the inner active area of each detector and are connected by a separate electric channel. When the guard rings are triggered (i.e., hit by particles coming outside of the FOV), the coincident measurements are considered invalid and are discarded. This anti-coincidence technique enables cleaner measurements of particles coming through the FOV. Figure 3.

Image Credit: Xinlin Li, University of Colorado Boulder To achieve high energy resolution, the team also applied full Pulse Height Analysis (PHA) on REPTile-2. In PHA, the magnitude of measured charge in the detector is directly proportional to the energy deposited from the incident electrons. Unlike REPTile, which employed a simpler energy threshold discrimination method yielding three channels for the electrons, REPTile-2 offers enhanced precision with 60 energy channels for electron energies ranging from 0.25 – 6 MeV. The REPT instrument onboard the Van Allen Probes also employed PHA but while REPT worked very well in the outer belt, yielding fine energy resolution, it did not function as well in the inner belt since the instrument was fully exposed to penetrating energetic protons because it did not have the guard rings implemented. Figure 4: The CIRBE team after a successful “plugs-out” test of the CIRBE spacecraft on July 21, 2022. During this test the CIRBE spacecraft successfully received commands from ground stations and completed various performance tests, including data transmission back to ground stations at LASP. Image Credit: Xinlin Li, University of Colorado Boulder CIRBE and REPTile-2 Results CIRBE’s launch, secured through the NASA CubeSat Launch Initiative (CSLI), took place aboard SpaceX’s Falcon 9 rocket as part of the Transporter-7 mission on April 15, 2023. REPTile-2, activated on April 19, 2023, has been performing well, delivering valuable data about Earth’s radiation belt electrons. Many features of the energetic electrons in the Van Allen belts have been revealed for the first time, thanks to the high-resolution energy and time measurements REPTile-2 has provided. Figure 5 shows a sample of CIRBE/REPTile-2 measurements from April 2024, and illustrates the intricate drift echoes or “zebra stripes” of energetic electrons, swirling around Earth in distinct bunches. These observations span a vast range across the inner and outer belts, encompassing a wide spectrum of energies and electron fluxes extending over six orders of magnitude. By leveraging advanced guard rings, Pulse Height Analysis (PHA), and a highly inclined LEO orbit, REPTile-2 is delivering unprecedented observations of radiation belt electrons. Figure 5: Color-coded electron fluxes detrended between REPTile-2 measurements for a pass over the South Atlantic Anomaly region on April 24, 2023, and their average, i.e., the smoothed electron fluxes using a moving average window of ±19% in energy; Black curves plotted on top of the color-coded electron fluxes are contours of electron drift period in hr. The second horizontal-axis, L, represents the magnetic field line, which CIRBE crosses. The two radiation belts and a slot region in between are indicated by the red lines and arrow, respectively. Image Credit: Xinlin Li, University of Colorado Boulder In fact, the team recently announced that measurements from CIRBE/REPTile-2 have revealed a new temporary third radiation belt composed of electrons and sandwiched between the two permanent belts. This belt formed during the magnetic storm in May 2024, which was the largest in two decades. While such temporary belts have been seen after big storms previously, the data from CIRBE/REPTile-2 are providing a new viewpoint with higher energy resolution data than before. Scientists are currently studying the data to better understand the belt and how long it might stick around — which could be many months.

The X-15 hypersonic rocket-powered aircraft, built by North American Aviation (NAA), greatly expanded our knowledge of flight at speeds exceeding Mach 6 and altitudes above 250,000 feet. A joint project among NASA, the U.S. Air Force, and the U.S. Navy, the X-15’s first powered flight took place on Sept. 17, 1959, at the Flight Research Center, now the Armstrong Flight Research Center, at Edwards Air Force Base (AFB) in California. NAA chief test pilot A. Scott Crossfield piloted this flight and other early test flights before NASA and the Air Force took ownership of the aircraft. Between 1959 and 1968, 12 pilots completed 199 missions and achieved ever higher speeds and altitudes, knowledge and experience that later influenced the development of future programs such as the space shuttle. Left: During its October 1958 rollout ceremony at the North American Aviation (NAA) facility in Los Angeles, NAA pilot A. Scott Crossfield poses in front of the X-15-1. Right: Rollout of X-15-2 at the NAA facility in February 1959. The origins of the X-15 date to 1952, when the Committee on Aerodynamics of the National Advisory Committee for Aeronautics (NACA) adopted a resolution to expand their research portfolio to study flight at altitudes between 12 and 50 miles and Mach numbers between 4 and 10. The Air Force and Navy agreed and conducted joint feasibility studies at NACA’s field centers. In 1955, the Air Force selected North American Aviation (NAA), Los Angeles, to build three X-15 hypersonic aircraft. On Oct. 1, 1958, the new National Aeronautics and Space Administration (NASA) incorporated the NACA centers and inherited the X-15 project. Two weeks later, on Oct. 15, 1958, the rollout of the first of the three aircraft took place at NAA’s Los Angeles facility where several of the early X-15 pilots, including Crossfield, attended. After the ceremony, workers wrapped the aircraft, placed it on a flatbed truck, and drove it overnight to the High Speed Flight Station, renamed by NASA the Flight Research Center in September 1959, where all the X-15 flights took place. Before this first aircraft took to the skies, NAA rolled out X-15-2 on Feb. 27, 1959. The X-15-3 rounded out the small fleet in early 1960.

Right: The twin XLR-11 engines, left, and the more powerful XLR-99 engine used to power the X-15. Like earlier X-planes, a carrier aircraft, in this case a modified B-52 Stratofortress, released the 34,000-pound X-15 at an altitude of 45,000 feet to conserve its fuel for the research mission. Flights took place within the High Range, a flight corridor extending from Wendover AFB in Utah to the Rogers Dry Lake landing zone adjacent to Edwards AFB, with emergency landing zones along the way. Typical research missions lasted eight to 12 minutes and followed either a high-altitude or a high-speed profile following launch from the B-52 and ignition of the X-15’s rocket engine. After burnout of the engine, the pilot guided the aircraft to an unpowered landing on the lakebed runway. To withstand the high temperatures during hypersonic flight and reentry, the X-15’s outer skin consisted of a then-new nickel-chrome alloy called Inconel-X. Because traditional aerodynamic surfaces used for flight control while in the atmosphere do not work in the near vacuum of space, the X-15 used its Ballistic Control System thrusters for attitude control while flying outside the atmosphere. NAA substituted eight smaller XLR-11 engines that produced only 16,000 pounds of thrust because of delays in the development of the 57,000-pound thrust XLR-99 rocket engine, built specifically for the X-15, For the first 17 months of test flights, the X-15 remained significantly underpowered. NAA chief pilot Crossfield had the primary responsibility for carrying out the initial test flights of the X-15 before handover of the aircraft to NASA and the Air Force.

With Crossfield at the controls of X-15-1, the first captive flight during which the X-15 remained attached to the B-52’s wing, took place on March 10, 1959. Crossfield completed the first unpowered glide flight of X-15-1 on June 8, the flight lasting just five minutes.

Scott Crossfield brings the X-15 to a smooth touchdown on the lakebed runway at Edwards Air Force Base in California. Image credit: courtesy North American Aviation. Right: Crossfield hops out of the cockpit at the conclusion of the X-15’s first successful powered flight. On Sept. 17, at the controls of X-15-2, Crossfield completed the first powered flight of an X-15. Firing all eight of the XLR-11 engines for 224 seconds, he reached a speed of Mach 2.11, or 1,393 miles per hour, and an altitude of 52,341 feet. Overcoming a few hardware problems, he brought the aircraft to a successful landing after a flight lasting just over nine minutes and traveling 88 miles. During 12 more flights, Crossfield expanded the aircraft’s flight envelope to Mach 2.97 and 88,116 feet while gathering important data on its flying characteristics. His last three flights used the higher thrust XLR-99 engine, the one designed for the aircraft. Crossfield’s 14th flight on Dec. 6, 1960, marked the end of the contracted testing program, and North American turned the X-15 over to the Air Force and NASA. Standing between the first two aircraft, North American Aviation chief test pilot A. Scott Crossfield, left, symbolically hands over the keys to the X-15 to U.S. Air Force pilot Robert M. White and NASA pilot Neil A. Armstrong at the conclusion of the contracted flight test program. Image credit: courtesy North American Aviation. Left: Chief NASA X-15 pilot Joseph “Joe” A. Walker following his altitude record-setting flight in August 1963. Middle left: Air Force pilot William J. “Pete” Knight following his speed record-setting flight in October 1967. Middle right: NASA pilot Neil A. Armstrong stands next to an X-15. Right: Air Force pilot Joe H. Engle following a flight aboard X-15A-2 in December 1965. Over nine years, Crossfield and 11 other pilots – five NASA, five U.S. Air Force, and one U.S. Navy – completed a total of 199 flights of the X-15, gathering data on the aerodynamic and thermal performance of the aircraft flying to the edge of space and returning to Earth. The pilots also conducted a series of experiments, taking advantage of the plane’s unique characteristics and flight environment. NASA chief pilot Joseph “Joe” A. Walker flew the first of his 25 flights in March 1960. On his final flight on Aug. 22, 1963, he took X-15-3 to an altitude of 354,200 feet, or 67.1 miles, the highest achieved in the X-15 program, and a record for piloted aircraft that stood until surpassed during the final flight of SpaceShipOne on Oct. 4, 2004. On Oct. 3, 1967, Air Force pilot William J. “Pete” Knight flew X-15A-2, with fully fueled external tanks, to an unofficial speed record for a piloted winged vehicle of Mach 6.70, or 4,520 miles per hour. The mark stood until surpassed during the reentry of space shuttle Columbia on April 14, 1981. NASA pilot Neil A. Armstrong and Air Force pilot Joe H. Engle flew the X-15 before joining NASA’s astronaut corps. Armstrong took to the skies seven times in the X-15 prior to becoming an astronaut, where he flew the Gemini VIII mission in 1966 and took humanity’s first steps on the Moon in July 1969. Engle has the unique distinction as the only person to have flown both the X-15 (16 times) and the space shuttle (twice in the atmosphere and twice in space). Of the first powered X-15 flight, Engle said, it “was a real milestone in a program that we still benefit from today.” Explore More 3 min read NASA, GE Aerospace Advancing Hybrid-Electric Airliners with HyTEC Article 3 hours ago 8 min read 55 Years Ago: Space Task Group Proposes Post-Apollo Plan to President Nixon Article 1 day ago 7 min read 15 Years Ago: Japan launches HTV-1, its First Resupply Mission to the Space Station Article 7 days ago View the full article

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This artist concept shows a NASA-developed small-core jet engine installed in General Electric Aerospace’s CFM RISE jet engine design. The more fuel-efficient small core powers a large open turbofan, which also helps increase efficiency. The effort is part of NASA’s Sustainable Flight National Partnership to help inform the next generation of ultra-efficient airliners.GE Aerospace Hybrid-electric cars have been a staple of the road for many years now. Soon that same idea of a part-electric-, part-gas-powered engine may find its way into the skies propelling a future jet airliner. NASA is working in tandem with industry partner GE Aerospace on designing and building just such an engine, one that burns much less fuel by including new components to help electrically power the engine. In this hybrid jet engine, a fuel-burning core powers the engine and is assisted by electric motors. The motors produce electric power, which is fed back into the engine itself—therefore reducing how much fuel is needed to power the engine in the first place. It really opens the door for more sustainable aviation even beyond the 2030s. Anthony nerone NASA Project Manager High Tech Hybrid-Electric The work is happening as part of NASA’s Hybrid Thermally Efficient Core (HyTEC) project. This work intends to demonstrate this engine concept by the end of 2028 to enable its use on airliners as soon as the 2030s. It represents a major step forward in jet engine technology. This jet engine would be the first ever mild hybrid-electric jet engine. A “mild hybrid” engine can be powered partially by electrical machines operating both as motors and generators. “This will be the first mild hybrid-electric engine and could lead to the first production engine for narrow-body airliners that’s hybrid electric,” said Anthony Nerone, who leads the HyTEC project from NASA’s Glenn Research Center in Cleveland. “It really opens the door for more sustainable aviation even beyond the 2030s.” The hybrid-electric technology envisioned by NASA and GE Aerospace also could be powered by a new small jet engine core. A major HyTEC project goal is to design and demonstrate a jet engine that has a smaller core but produces about the same amount of thrust as engines being flown today on single-aisle aircraft. At the same time, the smaller core technology aims to reduce fuel burn and emissions by an estimated 5 to 10%. Michael Presby, a research materials engineer at NASA’s Glenn Research Center in Cleveland, adjusts an infrared thermal imaging camera used to monitor the temperature profile of a NASA-developed, high-temperature environmental barrier coating deposited on a ceramic matrix composite in support of the agency’s HyTEC project. The composite’s environmental barrier coating surface temperature is 3,000 degrees Fahrenheit.NASA / Bridget Caswell How Does It Work? A GE Aerospace Passport engine is being modified with hybrid electric components for testing. “Today’s jet engines are not really hybrid electric,” Nerone said. “They have generators powering things like lights, radios, TV screens, and that kind of stuff. But not anything that can power the engines.” The challenge is figuring out the best times to use the electric motors. “Later this year, we are doing some testing with GE Aerospace to research which phases of flight we can get the most fuel savings,” Nerone said. Embedded electric motor-generators will optimize engine performance by creating a system that can work with or without energy storage like batteries. This could help accelerate the introduction of hybrid-electric technologies for commercial aviation prior to energy storage solutions being fully matured. “Together with NASA, GE Aerospace is doing critical research and development that could help make hybrid-electric commercial flight possible,” said Arjan Hegeman, general manager of future of flight technologies at GE Aerospace. The technologies related to HyTEC are among those GE Aerospace is working to mature and advance under CFM International’s Revolutionary Innovation for Sustainable Engines (RISE) program. CFM is a joint venture between GE Aerospace and Safran Aircraft Engines. CFM RISE, which debuted in 2021, encompasses a suite of technologies including advanced engine architectures and hybrid electric systems aimed at being compatible with 100% Sustainable Aviation Fuel. HyTEC, part of NASA’s Advanced Air Vehicles Program, is a key area of NASA’s Sustainable Flight National Partnership, which is collaborating with government, industry, and academic partners to address the U.S. goal of net-zero greenhouse gas emissions in aviation by the year 2050.

“I would say family and part of that ‘first-gen experience’ [shaped me]. Being born in the U.S. gave me a lot of opportunities that my family and parents were robbed of because of situations in their home country. It shaped me to be a hard worker and to aspire to large things because not only was it my goal at this point, but it was also my parents’ aspiration. “I feel that a lot of their pride comes from their kids. That pushes me to be a better employee or to want to do better for myself because I know that they’ve made a lot of sacrifices for me while I was building up to becoming an engineer. Now that I’ve accomplished my goal, it’s very important for me to always thank them and be a grateful person. “Culture also shaped me. Coming from a minority background, and I’m only familiar with the Hispanic culture, it was an education-first mindset…and very supportive. I think that’s important. When I do outreach, I always like to share my experiences because sometimes, people don’t realize how much impact they can have, like the teacher who told me about [a NASA] internship. She didn’t know that was going to be my career. Or, my mom staying up with me during late night study sessions when I was like, ‘I can’t be an engineer’ and failed a test and she was like, ‘No, you can do it. I believe in you.’ “It might not be memorable for the person who [says it], but it was super important for my motivation to keep going. So, [online, I am that voice for] first-gen motivation.” – Zaida Hernandez, Engineer, Lunar Architecture Team, NASA Johnson Space Center Image Credit: NASA/Bill Stafford Interviewer: NASA/Tahira Allen Check out some of our other Faces of NASA.

This is an image of the rim that the Perseverance rover took on sol 383 (March 19th, 2022) when it was traversing the crater floor. Dox Castle is located at the top of the image in the far ground. NASA/JPL-Caltech/ASU The Perseverance rover is reaching new heights as it ascends the rim of Jezero crater (over 300 meters in elevation higher than the original landing site)! The rover is now enroute to its first campaign science stop Dox Castle (image in the far ground) a region of interest for its potential to host ancient Mars’ bedrock in the exposed rocks on the rim. Impact craters like Jezero may be the key to piecing together the early geologic history of Mars, as they provide a window into the history of the ancient crust by excavating and depositing deep crustal materials above the surface. Crater rims act as keepers of ancient Martian history, uplifting and exposing the stratigraphy of these impacted materials. Additionally, extreme heat from the impact can encourage the circulation of fluids through fractures similar to hydrothermal vents, which have implications for early habitability and may be preserved in the exposed rim bedrock. With the Perseverance rover we have the potential to explore some of the oldest exposed rocks on the planet. Exploring such diverse terrains takes a lot of initial planning! The team has been preparing for the Crater Rim Campaign these last few months by working together to map out the types of materials Perseverance may encounter during its traverse up and through the rim. Using orbital images from the High-Resolution Imaging Science Experiment (HiRISE) instrument, the science team divided the rim area into 36 map quadrants, carefully mapping different rock units based on the morphologies, tones, and textures they observed in the orbital images. Mapping specialists then connected units across the quads to turn 36 miniature maps into one big geologic map of the crater rim. This resource is being used by the team to plan strategic routes to scientific areas of interest on the rim. On Earth, geologic maps are made using a combination of orbital images and mapping in the field. Planetary scientists don’t typically get to check their map in the field, but we have the unique opportunity to validate our map using our very own robot geologist! Dox Castle will be our first chance to do rim science – and we’re excited to search for evidence of the transition between the margin and rim materials to start piecing together the stratigraphic history of the rocks that make up the rim of Jezero crater.
