Larsson (KTH Royal Institute of Technology) NASA’s James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at its core formed either a neutron star or a black hole. Evidence for such a compact object has long been sought, and while indirect evidence for the presence of a neutron star has previously been found, this is the first time that the effects of high-energy emission from the probable young neutron star have been detected. Supernovae – the explosive final death throes of some massive stars – blast out within hours, and the brightness of the explosion peaks within a few months. The remains of the exploding star will continue to evolve at a rapid rate over the following decades, offering a rare opportunity for astronomers to study a key astronomical process in real time. Supernova 1987A The supernova SN 1987A occurred 160,000 light-years from Earth in the Large Magellanic Cloud. It was first observed on Earth in February 1987, and its brightness peaked in May of that year. It was the first supernova that could be seen with the naked eye since Kepler’s Supernova was observed in 1604. About two hours prior to the first visible-light observation of SN 1987A, three observatories around the world detected a burst of neutrinos lasting only a few seconds. The two different types of observations were linked to the same supernova event, and provided important evidence to inform the theory of how core-collapse supernovae take place. This theory included the expectation that this type of supernova would form a neutron star or a black hole. Astronomers have searched for evidence for one or the other of these compact objects at the center of the expanding remnant material ever since. Indirect evidence for the presence of a neutron star at the center of the remnant has been found in the past few years, and observations of much older supernova remnants –such as the Crab Nebula – confirm that neutron stars are found in many supernova remnants. However, no direct evidence of a neutron star in the aftermath of SN 1987A (or any other such recent supernova explosion) had been observed, until now. Image: Supernova 1987A The James Webb Space Telescope has observed the best evidence yet for emission from a neutron star at the site of a well-known and recently-observed supernova known as SN 1987A. At left is a NIRCam (Near-Infrared Camera) image released in 2023. The image at top right shows light from singly ionized argon (Argon II) captured by the Medium Resolution Spectrograph (MRS) mode of MIRI (Mid-Infrared Instrument). The image at bottom right shows light from multiply ionized argon captured by the NIRSpec (Near-Infrared Spectrograph). Both instruments show a strong signal from the center of the supernova remnant. This indicated to the science team that there is a source of high-energy radiation there, most likely a neutron star. NASA, ESA, CSA, STScI, C. Fransson (Stockholm University), M. Matsuura (Cardiff University), M. J. Barlow (University College London), P. J. Kavanagh (Maynooth University), J. Larsson (KTH Royal Institute of Technology) Claes Fransson of Stockholm University, and the lead author on this study, explained: “From theoretical models of SN 1987A, the 10-second burst of neutrinos observed just before the supernova implied that a neutron star or black hole was formed in the explosion. But we have not observed any compelling signature of such a newborn object from any supernova explosion. With this observatory, we have now found direct evidence for emission triggered by the newborn compact object, most likely a neutron star.” Webb’s Observations of SN 1987A Webb began science observations in July 2022, and the Webb observations behind this work were taken on July 16, making the SN 1987A remnant one of the first objects observed by Webb. The team used the Medium Resolution Spectrograph (MRS) mode of Webb’s MIRI (Mid-Infrared Instrument), which members of the same team helped to develop. The MRS is a type of instrument known as an Integral Field Unit (IFU). IFUs are able to image an object and take a spectrum of it at the same time. An IFU forms a spectrum at each pixel, allowing observers to see spectroscopic differences across the object. Analysis of the Doppler shift of each spectrum also permits the evaluation of the velocity at each position. Spectral analysis of the results showed a strong signal due to ionized argon from the center of the ejected material that surrounds the original site of SN 1987A. Subsequent observations using Webb’s NIRSpec (Near-Infrared Spectrograph) IFU at shorter wavelengths found even more heavily ionized chemical elements, particularly five times ionized argon (meaning argon atoms that have lost five of their 18 electrons). Such ions require highly energetic photons to form, and those photons have to come from somewhere. “To create these ions that we observed in the ejecta, it was clear that there had to be a source of high-energy radiation in the center of the SN 1987A remnant,” Fransson said. “In the paper we discuss different possibilities, finding that only a few scenarios are likely, and all of these involve a newly born neutron star.” More observations are planned this year, with Webb and ground-based telescopes. The research team hopes ongoing study will provide more clarity about exactly what is happening in the heart of the SN 1987A remnant. These observations will hopefully stimulate the development of more detailed models, ultimately enabling astronomers to better understand not just SN 1987A, but all core-collapse supernovae. These findings were published in the journal Science. The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

NASA/Jasmin Moghbeli While the International Space Station orbited 260 miles above the East China Sea, NASA astronaut Jasmin Moghbeli snapped this photo of Shanghai’s city lights and the Huangpu River flowing through downtown. Shanghai is the most populous city in China with a population of about 24.9 million. The space station serves as a unique platform for observing Earth with both hands-on and automated equipment. Station crew members have produced hundreds of thousands of images, recording phenomena such as storms in real time, observing natural events such as volcanic eruptions as they happen, and providing input to ground personnel for programming automated Earth-sensing systems. Having a crew on board provides flexibility, a significant advantage over sensors on robotic spacecraft. Astronauts take images using handheld digital cameras, usually through windows in the station’s cupola, for Crew Earth Observations. Image Credit: NASA/Jasmin Moghbeli View the full article

Engineering is a huge field with endless applications. From aerospace to ergonomics, engineers play an important role in designing, building, and testing technologies all around us. We asked three engineers at NASA’s Ames Research Center in California’s Silicon Valley to share their experiences, from early challenges they faced in their careers to the day-to-day of being a working engineer. Give us a look behind the curtain – what is it like being an engineer at NASA? In her early days at NASA, Diana Acosta visited her aeronautics research and development team during her maternity leave and her daughter got her first introduction to flight simulation technology. NASA/Diana Acosta Diana Acosta: I remember working on my first simulations. We were developing new aircraft with higher efficiency that could operate in new places, such as shorter runways. My team was putting together control techniques and introducing new algorithms to help pilots fly these new aircraft in a safer way. We were creating models and testing, then changing things and testing again. We had a simulator that worked on my laptop, and we had a lab with a pilot seat and controls. Every week, I made it my goal to finish my modeling or controls work and put that into the lab environment so that I could fly the aircraft. Every Friday afternoon, I would fly the aircraft in simulation and try out the changes I’d made to see if we were going in a good direction. We’d later integrate that into the Vertical Motion Simulator at Ames (which was used to train all the original space shuttle pilots) so that we could do a full motion test with a collection of pilots to get feedback. When simulation time came around, it was during my maternity leave and my team had to take the project to simulation without me. It’s hard to get out of the house with a newborn, but sometimes I’d come by with my daughter and bring brownies to the team. I have two daughters now, and they’ve both been in simulators since a young age. Diana Acosta is Chief of the Aerospace Simulation and Development Branch at NASA’s Ames Research Center. She has worked at NASA for 17 years. What’s a challenge you’ve overcome to become an engineer? Savvy Verma (standing) reviews simulation activity with Gus Guerra in the Terminal Tactical Separation Assured Flight Environment at NASA’s Ames Research Center in California’s Silicon Valley. NASA/Dominic Hart Savvy Verma: One of the biggest challenges when I started working was that I was sometimes the only woman in a group of men, and I was also much younger. It was sometimes a challenge to get my voice through, or to be heard. I had mentors who taught me to speak up and say things the way I saw them, and that’s what helped me. A good mentor will back you up and support you when you’re in big meetings or giving presentations. They’ll stand up and corroborate you when you’re right, and that goes a long way toward establishing your credibility. It also helped build my confidence, it made me feel like I was on the right track and not out of line. I had both male and female mentors. The female mentor I had always encouraged me to speak my mind. She said the integrity of the experimental result is more important than trying to change things because someone doesn’t like it or doesn’t want to express it a certain way. I have a lot more women coworkers now, things have changed a lot. In my group there are four women and three men. When you want to become an engineer, you must remain adaptable, hardworking, and always willing to learn something new. We’re constantly learning, critically thinking, and problem solving. Most of the time we apply mathematical concepts to the engineering problems we’re solving and not every problem is the same. If you struggle with math, my advice is to maintain the passion for learning, especially learning from your mistakes. It comes down to practicing and challenging yourself to think beyond the immediate struggle. There are so many types of math problems and if you’re not good at one, maybe you’re good at another. Maybe it’s just a hiccup. Also, seek help when you need it, there are instructors and peers out there willing to support you. Savvy Verma is an aerospace engineer at NASA’s Ames Research Center. She has worked at NASA for 22 years. Can you become an engineer if you struggle with math in school? Dorcas Kaweesa: When I introduce myself as an engineer, people always say, “You must be good at math,” and I say, “Oh, I work at it.” When you want to become an engineer, you must remain adaptable, hardworking, and always willing to learn something new.

I also practiced a great deal to improve my problem solving and critical thinking skills. In my current role, I am constantly learning new things based on the task at hand. Learning never ends! If you’re struggling with a math concept, don’t give up. Keep trying, keep accepting the challenge, and keep practicing, you’ll steadily make progress.

NASA’s Josh Whitehead has a passion for systems engineering. He now helps lead the team developing the rocket that will fly the first crew to deep space since the Saturn V. The campaign name of Artemis, the Greek goddess of the Moon, also has special meaning for Whitehead. “I have a twin sister, and Artemis is the twin sister of Apollo. I’m like, hey, I’m a twin! How cool is that?”NASA/Sam Lott Launching a rocket to the Moon takes perseverance and diligence. Josh Whitehead – a world-class engineer, race-winning long-distance runner, and father – knows that it also takes a good attitude. “Positive energies are vital, particularly when working through challenges,” Whitehead says. “Challenges are opportunities to learn and grow. There’s always more than one way; always more than one solution.” Whitehead’s job as the associate manager for the Stages Office of NASA’s SLS (Space Launch System) rocket supports design, development, certification, and operation of the 212-foot-tall SLS core stage. The massive core stage with two propellant tanks that collectively hold more than 733,000 gallons of super-cold propellant is one of the largest cryogenic propulsion rocket stages. Whitehead joined the SLS Program, based at NASA’s Marshall Space Flight Center in Huntsville, Alabama, early on during the COVID-19 pandemic. Complicating matters further, in June 2020, Whitehead was injured in a hit-and-run cycling accident so devastating that it separated his right shoulder and broke his back in three places. Amid his necessary rehabilitation and surgeries, Whitehead learned to type left-handed and one-handed. Through it all, he was working to further the agency’s Artemis campaign and preparing for the first launch of the SLS rocket for Artemis I. Now back to running and having participated in a local charity race every year since 2007, the avid runner and engineer will tell you that, like a recovery, the road to launch is not a sprint. It’s a cadenced effort as teams across the country worked toward a common goal. During his rehabilitation and path to run again, Whitehead and his team finished assembling the first SLS core stage and the successful eight-part Green Run test campaign of the entire stage at NASA’s Stennis Space Center in Bay St. Louis, Mississippi, prior to the Nov. 16, 2022, Artemis I launch. Whitehead and his team are now manufacturing and processing core stages for multiple Artemis missions, including Artemis II in 2025, the first crewed flight under Artemis that will test the life-supporting systems in the Orion spacecraft ahead of future lunar missions. Whitehead holds multiple advanced degrees in engineering from Auburn University and the University of Alabama in Huntsville. He got his start in the aerospace industry conducting subscale motor manufacturing tests for NASA’s Space Shuttle Program. From systems engineering supporting NASA’s Constellation Program and verifying and validating the solid rocket booster element in the SLS Program’s early days, to qualification activities and safety and mission assurance for the Artemis I flight, Whitehead has a passion for cross-discipline work. “Being able to work systems engineering activities and multiple elements is all complementary. But the common thread is it’s about the people, the process, and the product,” he said. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. View the full article

5 Min Read NASA’s Planetary Protection Team Conducts Vital Research for Deep Space Missions Cassilly examines fungal growth obtained from a space environmental exposure study, part of the Planetary Protection team’s work to understand the ability of microbes to survive conditions in deep space. Credits: NASA/Charles Beason By Celine Smith As NASA continues its exploration of the solar system, including future crewed missions to Mars, experts in the agency’s Office of Planetary Protection are developing advanced tactics to prevent NASA expeditions from introducing biological contaminants to other worlds. At NASA’s Marshall Space Flight Center in Huntsville, Alabama, the Planetary Protection team is contributing to this work – pursuing new detection, cleaning, and decontamination methods that will protect alien biospheres, safeguard future planetary science missions, and prevent potentially hazardous microbes from being returned to Earth. The Planetary Protection team is a part of the Space Environmental Effects (SEE) team in Marshall’s Materials and Processes Laboratory. Chelsi Cassilly, lead of Marshall Space Flight Center’s Planetary Protection Laboratory, researches microbes and their behaviors to preserve the environment of other planetary bodies after future missions. NASA/Charles Beason Planetary Protection microbiologist Chelsi Cassilly said much of Planetary Protection focuses on “bioburden” which is typically considered the number of bacterial endospores (commonly referred to as “spores”) found on and in materials. Such materials can range from paints and coatings on robotic landers to solid propellants in solid rocket motors. NASA currently requires robotic missions to Mars meet strict bioburden limits and is assessing how to apply similar policies to future, crewed missions to the Red Planet. “It’s impossible to eliminate microbes completely,” Cassily said. “But it’s our job to minimize bioburden, keeping the probability of contamination sufficiently low to protect the extraterrestrial environments we explore.” Currently, Marshall’s Planetary Protection research supports NASA’s Mars Ascent Vehicle, a key component of the planned Mars Sample Return campaign, and risk-reduction efforts for the Human Landing System program. Critically, Planetary Protection prevents the introduction of microbes from Earth onto planetary bodies where they might proliferate and subsequently interfere with scientific study of past or current life there. If Earth’s microbes were to contaminate samples collected on Mars or Europa, the scientific findings would be an inaccurate depiction of these environments, potentially precluding the ability to determine if life ever existed there. Preserving the scientific integrity of these missions is of the utmost importance to Cassilly and her team. Contamination mitigation tactics used in the past also may not work with modern hardware and materials. For the Viking missions to Mars, NASA employed a total spacecraft “heat microbial reduction” (HMR) process, a prolonged exposure to high temperatures to kill off or minimize microbes. As spacecrafts advance, NASA is more discerning, using HMR for components and/or subassemblies instead of the entire spacecraft. According to Cassilly, HMR may not always be an ideal solution because, extended time at high temperatures required to kill microbes can degrade the integrity of certain materials, potentially impacting mission success. While this is not a problem for all materials, there is still a need to expand NASA’s repertoire of acceptable microbial reduction techniques to include ones that may be more efficient and sustainable. This mold from the genus Cladosporium was collected from the surface of a cleanroom table at Marshall. This and other microbes within cleanrooms pose the biggest threat to spacecraft cleanliness and meeting Planetary Protection requirements. Jacobs Engineering/Chelsi Cassilly To contribute to NASA’s Planetary Protection efforts, Cassilly undertook a project – funded by a Jacobs Innovation Grant – to build a microbial library that could better inform and guide mitigation research. That meant visiting cleanrooms at Marshall to collect prevalent microbes, extracting DNA, amplifying specific genes, and submitting them for commercial sequencing. They identified 95% of the microbes within their library which is continually growing as more microbes are collected and identified. The Planetary Protection team is interested in taking this work a step further by exposing their microbial library to space-like stressors—including ultraviolet light, ionizing radiation, temperature extremes, desiccation, and vacuum—to determine survivability. Understanding the response of these microbes to space environmental conditions, like those experienced during deep space transit, helps inform our understanding of contamination risks associated with proposed planetary missions. Chelsi Cassilly Planetary Protection microbiologist “The research we’re doing probes at the possibility of using space itself to our advantage,” Cassilly said. Cassilly and Marshall materials engineers also supported a study at Auburn University in Auburn, Alabama, to determine whether certain manufacturing processes effectively reduce bioburden. Funded by a NASA Research Opportunity in Space and Earth Sciences (ROSES) grant, the project assessed the antimicrobial activity of various additives and components used in solid rocket motor production. The team is currently revising a manuscript which should appear publicly in the coming months. This Bacillus isolate with striking morphology was collected from a sample of insulation commonly used in solid rocket motors. Cassilly studies these and other material-associated microbes to evaluate what could hitch a ride on spacecraft. Jacobs Engineering/Chelsi Cassilly Cassilly also supported research by Marshall’s Solid Propulsion and Pyrotechnic Devices Branch to assess estimates of microbial contamination associated with a variety of commonly used nonmetallic spacecraft materials. The results showed that nearly all the materials analyzed carry a lower microbial load than previously estimated – possibly decreasing the risk associated with sending these materials to sensitive locations. Such findings benefit researchers across NASA who are also pursuing novel bioburden reduction tactics, Cassilly said, improving agencywide standards for identifying, measuring, and studying advanced planetary protection techniques. “Collaboration unifies our efforts and makes it so much more possible to uncover new solutions than if we were all working individually,” she said. NASA’s Office of Planetary Protection is part of the agency’s Office of Safety and Mission Assurance at NASA Headquarters in Washington. The Office of Planetary Protection oversees bioburden reduction research and development of advanced strategies for contamination mitigation at Marshall Space Flight Center; NASA’s Jet Propulsion Laboratory in Pasadena, California; NASA’s Goddard Space Flight Center in Greenbelt, Maryland; and NASA’s Johnson Space Center in Houston.

Teams at NASA’s Stennis Space Center install a new RS-25 engine nozzle in early February in preparation for continued testing on the Fred Haise Test Stand. NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin NASA will conduct an RS-25 hot fire Friday, Feb. 23, moving one step closer to production of new engines that will help power the agency’s SLS (Space Launch System) rocket on future Artemis missions to the Moon and beyond. Teams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, are set to begin the second half of a 12-test RS-25 certification series on the Fred Haise Test Stand, following installation of a second production nozzle on the engine.

NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin The six remaining hot fires are part of the second, and final, test series collecting data to certify an updated engine production process, using innovative manufacturing techniques, for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company. As NASA aims to establish a long-term presence on the Moon for scientific discovery and exploration, and prepare for future missions to Mars, new engines will incorporate dozens of improvements to make production more efficient and affordable while maintaining high performance and reliability. Four RS-25 engines, along with a pair of solid rocket boosters, launch NASA’s powerful SLS rocket, producing more than 8.8 million pounds of thrust at liftoff for Artemis missions. During the seventh test of the 12-test series, operators plan to fire the certification engine for 550 seconds and up to a 113% power level. “NASA’s commitment to safety and ‘testing like you fly’ is on display as we plan to fire the engine beyond 500 seconds, which is the same amount of time the engines must fire to help launch the SLS rocket to space with astronauts aboard the Orion spacecraft,” said Chip Ellis, project manager for RS-25 testing at Stennis. The Feb. 23 test features a second certification engine nozzle to allow engineers to gather additional performance data on the upgraded unit. The new nozzle was installed on the engine earlier this month while it remained at the test stand. Using specially adapted procedures and tools, the teams were able to swap out the nozzles with the engine in place.

NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin In early February 2024, teams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, completed an RS-25 nozzle remove-and-replace procedure as part of an ongoing hot fire series on the Fred Haise Test Stand. The new nozzle will allow engineers to collect and compare performance data on a second production unit. The RS-25 nozzle, which directs engine thrust, is the most labor-intensive component on the engine and the hardest to manufacture, said Shawn Buckley, Aerojet Rocketdyne’s RS-25 nozzle integrated product team lead. Aerojet Rocketdyne has focused on streamlining the nozzle production process. Between manufacture of the first and second production units, the company reduced hands-on labor by 17%. “The nozzle is a work of machinery and work of art at the same time,” Buckley said. “Our team sees this nozzle as more than a piece of hardware. We see the role we play in the big picture as we return humans to the Moon.” With completion of the certification test series, all systems will be “go” to produce the first new RS-25 engines since the space shuttle era. NASA has contracted with Aerojet Rocketdyne to produce 24 new RS-25 engines using the updated design for missions beginning with Artemis V. NASA and Aerojet Rocketdyne modified 16 former space shuttle missions for use on Artemis missions I through IV. Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

Planet Hunting with NASA's Curious Universe Podcast Host Padi Boyd

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA pilots flew this YF-12C aircraft from 1971 and 1978 to perform airspeed calibrations and collect propulsion system data at numerous flight conditions.Credit: NASA Supersonic flight became a reality in October 1947, when the Bell X-1 rocket plane broke the sound barrier. NASA’s Lewis Research Center in Cleveland (now, NASA Glenn), which had served as the agency’s aeropropulsion leader since it was established in the 1940s, subsequently helped NASA advance the technology needed to make longer supersonic flights possible. A host of military aircraft capable of reaching supersonic speeds followed the Bell X-1. In the 1960s, Lockheed’s family of Blackbirds (the original A-12, the YF-12 interceptor, and the SR-71 reconnaissance vehicle) became the world’s first aircraft able to cruise at supersonic speeds for extended periods. However, the expansion of this capability to larger transport aircraft was difficult, in large part due to the lack of data collected about propulsion systems during longer supersonic flights. To solve problems that weren’t found during design-phase testing of these aircraft and to advance crucial technology, like the supersonic mixed-compression inlet, the military loaned two retired YF-12s to the Dryden Flight Research Center (today, NASA Armstrong) in 1969 as part of a collaborative NASA/Air Force effort. They planned to compare data from YF-12 flights to data collected in wind tunnels at NASA’s Ames, Langley, and Lewis Research Centers. Bobby Sanders (left) and Robert Coltrin check a full-scale YF-12 flight inlet prior to a February 1972 test run in the NASA Lewis Research Center (now NASA Glenn) 10×10 Supersonic Wind Tunnel. Although the 5-foot 9-inch diameter inlet was large for the test section, no problems aroseCredit: NASA/Martin Brown Lewis’ researchers had studied supersonic inlets in wind tunnels since the early 1950s and were in the midst of an extensive evaluation of supersonic nozzles and inlets using an F-106 Delta Dart. In this new effort, Lewis was responsible for testing a full-scale YF-12 inlet in the center’s 10×10 Supersonic Wind Tunnel and analyzing a 32,500-pound thrust Pratt & Whitney J58 engine in the Propulsion Systems Laboratory (PSL). Although mixed-compression inlets, which allowed the engines to operate as turbojets at subsonic speeds and as ramjets at higher Mach numbers, were highly efficient, their design left the engines vulnerable to flow disturbances that often caused “unstarts.” Unstarts produced instantaneous drag that could stall the engine or cause the aircraft to quickly roll or yaw. Lewis researchers tested an actual inlet from a crashed SR-71, which they installed into the 10×10 in November 1971. Over the next year, researchers collected aerodynamic data under different conditions in the wind tunnel. They also tested a new inlet control system patented by Lewis engineers Bobby Sanders and Glenn Mitchell that used mechanical valves to protect the aircraft against unstarts. It was the first time the system was tested on a full-scale piece of hardware. Researchers also studied the relationships between the airframe, inlet, engine, and control system during normal flight conditions and when experiencing realistic flow disturbances. A Pratt & Whitney J58 engine installed in the NASA Lewis Research Center (now, NASA Glenn) Propulsion Systems Laboratory No. 4 facility in November 1973. The center’s technicians had to take great precautions to protect the instrumentation and control systems from the engine’s 1000-degree-Fahrenheit surface temperatures during the testing. Credit: NASA/Martin Brown In the summer of 1973, a full-scale J-58 engine became the first hardware tested in Lewis’ new PSL second altitude chamber. For the next year, researchers captured data under normal conditions and while using mesh inlet screens to simulate in-flight air-flow distortions. The PSL tests also measured the engine’s emissions as part of a larger effort to determine the high-altitude emissions levels of potential supersonic transports. While the YF-12 program was terminated in 1979 as the agency’s aeronautical priorities shifted, a year’s worth of ground testing had already been completed in NASA’s wind tunnels and the YF-12s had completed nearly 300 research flights. The program had expanded to include the development of high-temperature instrumentation, airframe pressure and flow mapping, thermal loads, and the inlet control system. NASA engineers demonstrated that small-scale models could be successfully used to design full-scale supersonic inlets, while the flight data was used to better understand the effect of subscale models and tunnel interference on data. Perhaps most importantly, the program at Lewis led to a digital control system that improved the response of the supersonic inlet to flow disturbances, which nearly eliminated engine restarts. Many of the program’s concepts were integrated into the SR-71’s design in the early 1980s and have contributed to NASA’s continuing efforts over the decades to achieve a supersonic transport aircraft.

30 Min Read The Marshall Star for February 21, 2024 Marshall Center Director Holds First Media Event By Jessica Barnett NASA Marshall Space Flight Center’s newest center director, Joseph Pelfrey, took to the podium Feb. 15 in the lobby of Building 4221 to host his first media event since his appointment to the position. Pelfrey, who had been serving as acting center director since August 2023, is the 15th center director for Marshall. He succeeded Jody Singer, who retired in July 2023. Marshall Center Director Joseph Pelfrey, far right, talks to reporters during his first media event since accepting the director position. The event was held Feb. 15 in the lobby of Building 4221. NASA/Charles Beason Appearing before local news cameras and reporters, Pelfrey said he was humbled and honored to receive the call from NASA Administrator Bill Nelson with news of his selection. “The agency is committed to Marshall’s role in supporting what we do as a nation in space exploration,” Pelfrey said. “I am honored that they have confidence in me and our team to continue to lead.” Pelfrey took the opportunity to speak to reporters about upcoming milestones for the center, such as the celebration of 25 years of work with the Chandra X-ray Observatory, Marshall’s 30th year hosting the Human Exploration Rover Challenge, two years since the launches of the James Webb Space Telescope and IXPE (Imaging X-ray Polarimetry Explorer) observatory, and the recent launch of the LN-1 (Lunar Node 1) navigation beacon. He also discussed the center’s plans to use more of its testing capabilities for habitation systems; build a new Engineering Science Laboratory to replace Building 4487; build the Marshall Exploration Facility where Building 4200 once stood; and continue supporting operations at the International Space Station and for future Artemis missions. Looking to the future, Pelfrey said Marshall is focused on helping NASA expand its missions in deep space and developing the technologies needed to carry astronauts farther than “we’ve ever been before.” A child of the shuttle generation, Pelfrey recalled watching launches and dreaming of a career at NASA. He said he’s honored to follow behind great center leaders, continuing Marshall’s legacy as a leader in space exploration. “As we write the next chapter of our story, I am confident of the bright future we have at Marshall Space Flight Center,” he said.

The meeting – with the theme “More to Marshall” – was Pelfrey’s first all-hands since NASA Administrator Bill Nelson named him as the center’s 15th director Feb. 5. Pelfrey had served as acting director since Jody Singer’s retirement in July 2023. NASA Marshall Space Flight Center Director Joseph Pelfrey, standing, discusses the direction of Marshall and the center’s upcoming projects and strategies during the first all-hands meeting of 2024. Joining him on stage, from left, are Tia Ferguson, Marshall’s Space Systems Department director in the Engineering Directorate, Associate Center Director Rae Ann Meyer, and Mallory James, an aerospace engineer and management assistant in the office of the center director. NASA/Charles Beason Along with Pelfrey, Tia Ferguson, director of Marshall’s Space Systems Department in the Engineering Directorate, Rae Ann Meyer, associate center director, and Mallory James, an aerospace engineer and management assistant in the office of the center director, gave presentations about the direction of Marshall in 2024. “I see us embracing a transformative shift to a portfolio of more small and medium-sized projects enabled through strategic partnerships while also being a technical solutions provider to NASA and our partners,” Pelfrey said. “I see a very bright future for our center, and I’m excited to write this next chapter with all of you.” Pelfrey commended Marshall team members for submitting 63 proposals to NASA’s Space Technology Mission Directorate, all enabled by partnerships. Marshall submitted and won the most proposals out of all NASA centers. He encouraged team members to continue creating and working on more innovative ideas to support future Agency needs. Pelfrey gave updates on Marshall’s various projects, including Lunar Node-1 using the Huntsville Operation Support Center for its mission and Marshall partnering with the Italian Space Agency to create a multipurpose habitat that could be used on the Moon. The habitat is in the process of becoming a part of the Artemis architecture and would be the first of its kind on the lunar surface. Pelfrey shared that Marshall and industry partners will be leading the development of the engine in collaboration with the Department of the Defense for NASA and DARPA’s DRACO (Demonstration Rocket for Agile Cislunar Operations), the first nuclear thermal flight demonstration intended for the mission to Mars. Pelfrey also highlighted the development of the solar sail prototype, which is approximately 4,700 square feet and was recently tested with NASA’s industry partner. The potential for this design has drawn attention from future science missions and the Department of Defense due to its advancements in propulsion. Pelfrey also mentioned that NASA’s Michoud Assembly Facility, which is managed by Marshall, is manufacturing parts for Artemis III-V. Pertaining to the Artemis Mission, Pelfrey said the data from Artemis I is being examined to prepare for Artemis II. Flight software testing has been completed for Artemis II as well. The Human Landing System team is continuing to work with lander partner, SpaceX, which is preparing for the next Starship orbital flight test in the next few weeks. Brandon Phillips, a material science engineer, asks a question during the Q&A portion of the all-hands meeting. NASA/Charles Beason According to Pelfrey, Marshall is also expecting two new buildings, the Marshall Exploration Facility, which is tentatively scheduled to break ground in 2026, and an Engineering Science Lab, a replacement for Building 4487. Ferguson followed Pelfrey’s presentation with updates about NASA 2040, an agency strategic initiative propelling NASA into the future. The initiative aims to drive meaningful changes in the present to ensure that, in 2040, NASA remains the preeminent institution for research, technology, and engineering, to lead science, aeronautics, and space exploration for humanity. She went into detail about plans made to optimize the internaloperations of the agency and improving the work environment for team members to achieve mission goals. Meyer discussed how Marshall’s culture reflects the changes and new strategies taking place. Meyer emphasized the investment in centerwide events to strengthen culture at Marshall. James, a mentee of Meyer, gave the last presentation. She discussed the results of the Federal Employee Viewpoint Survey and how leadership is moving forward to address concerns expressed from the results. All-hands ended with a Q&A panel with Pelfrey, Ferguson, Meyer, and James. Larry Leopard, associate director, technical, also joined the panel. They answered questions submitted online and from the audience. “With our long history of what we’ve done at the center, there’s so much more to Marshall that we can achieve,” Pelfrey said in his closing remarks. “There’s so much more that we can dare to dream and explore and innovate for the agency and there’s more to gain when we do it together.” Smith, a Media Fusion employee, supports the Marshall Office of Communications. › Back to Top Black History Month Profile: Evolving with Leslie Smith By Celine Smith Ever since Leslie Smith was young, she has liked working with her hands, whether it be arts and crafts or playing the piano. Watching her father weld pieces of scrap metal into something new reinforced her enthusiasm for designing and creating. While working for NASA’s Marshall Space Flight Center, Smith has been able to pursue her passion of more tactile work while also gaining an array of other skills. Leslie Smith is the task manager of the Sustaining Lunar Development program.MSFC/Emmett Given “Helping put the next man and first woman on the Moon gives me a sense of pride, especially because it could help us get to Mars,” said Smith, who is the task manager of the Sustaining Lunar Development program. “I love knowing I’m helping the next generation and just being a part of the program.” As a young girl, Smith aspired to be an architect, which combined her two favorite skills of designing and building. While in high school, Smith began to co-op at a technical vocational school. Her interest in architecture increased when she was introduced to CAD (computerized-aided design) software in a drafting class. After Smith started at Tuskegee University, a historically Black university in Alabama, her sights changed. “The architecture class seemed more artsy, and not as focused on design or manufacturing, which is what I really wanted to do,” said Smith, who is from Vicksburg, Mississippi. She decided to major in mechanical engineering instead. Before graduating, Smith signed an offer for a co-op opportunity with Marshall during a 2008 Tuskegee job fair, leading to her 15-year career at the center. During Smith’s start, she didn’t get to immediately do the CAD work she originally was drawn to. Smith began working in the Planning and Operations branch within the Mission Ops Lab. She oversaw the countdown timeline for operational tasks and filled out functional objective sheets for the Constellation program’s Ares I. Later, she performed 3D CAD modeling for the main propulsion system and 2D drawings and assemblies for the cryogenic propellant storage and transfer system. The experience served as Smith’s introduction to program management and systems engineering. While her role was not originally in her area of interest, she found a reason to stay. “I stayed because of the people,” Smith said. “They were very friendly and helpful. Also, after taking a tour of Marshall, I saw all capabilities of the center. Marshall’s friction stir welding, 3D printing, the propulsion lab, and the diverse types of engineering intrigued me.” Her first full-time role at Marshall took place after graduating college. She began as a design engineer in the Propulsion Detailed Design branch in 2013. She used her CAD skills to draft a 1 Newton thruster, an adapter for secondary payloads, and a core stage auxiliary power unit among other projects. Smith also did some friction stir welding and additive manufacturing, the processes that interested her during her co-op days. Before becoming a key coordinator for human landing systems, she conducted trade studies for SLS (Space Launch System) components as a systems engineer in 2018. Now, Smith manages human landing system concepts, focused on reducing risk and the advancement of key technologies. “I’m the kind of person who likes to do something different every so often,” she said. “Technology is always evolving so that makes me want to always evolve.” Smith’s passion for engineering is present in her personal life. As a member of the National Society of Black Engineers, she took part in the Arusha Project, started at NASA’s Johnson Space Center. Arusha is Swahili for “he makes fly (into the skies).” Smith joined other Black engineers to build a rover for potential Moon and Mars missions. Smith personally worked on the outer shell, window, and chassis. “The project was great because you got to work with other African American engineers and other ethnicities,” she said. “It’s important to be around people who look like you and can relate to similar issues.” In Smith’s free time she volunteers to do STEM outreach. She also enjoys basketball, swimming, and reading. Smith currently lives in Madison, Alabama. Her advice for young engineers at Marshall is to: “learn all you can. Talk to as many people as you can, particularly people who are different from you for a different perspective. Never pass an opportunity to see hardware. Take all the tours and attend mentoring events.” First in a two-part series in the Marshall Star highlighting team members during Black History Month.

The 11:30 a.m. event will be in Activities Building 4316 for Marshall team members. Light refreshments will be served. The forum is available to NASA employees and the public virtually via Teams. Mission Success Is in Our Hands is a safety initiative collaboration between NASA’s Marshall Space Flight Center and Jacobs Engineering. The initiative’s goal to help team members make meaningful connections between their jobs and the safety and success of NASA and Marshall missions. The theme of the forum is “The Impact of Breaking the Silence.” Conway will address the elements and factors that can contribute to organizational silence, including the failure to draw attention to problems that can potentially result in mission failures. He will detail practical tactics and tools to help combat this issue and identify methods of creating organizational excellence from the perspectives of both leadership and front-line employees. Bill Hill, director of Safety and Mission Assurance at Marshall, encourages team members to attend the forum in-person. “Administrator (Bill) Nelson has requested that all NASA civil servants and contractors hear Bob Conway’s organizational silence briefing and learn tools and techniques to avoid the pitfalls of organizational silence,” Hill said. Jeff Haars, Jacobs vice president and program manager for Jacobs Space Exploration Group, said the Shared Experiences Forum is an impactful reminder on safety. “At Jacobs, we put a high priority on safety so it’s very reassuring to have a great safety partner like Marshall,” Haars said. “Working as a team allows us to deliver our work safely while contributing to mission success.” Conway works with the NASA Safety Center’s director to enable more effective and efficient safety and mission assurance support for NASA’s portfolio of programs and projects by managing the safety center’s activities in knowledge sharing and analysis, technical excellence, and assessments and investigations. Prior to assuming this role, Conway worked in the civilian sector as the manager of Quality Engineering for Worldwide Safety and Health at the Walt Disney World Resort in Orlando, Florida, from 2012 to 2019. Conway was also a member of the NASA Aerospace Safety Advisory Panel from 2012 to 2016. In this role he evaluated various NASA programs and, with his Naval Aviation Safety background, was the lead panel representative to the NASA Aircraft Mission Directorate. After his commissioning as an ensign, Conway served in the U.S. Navy through his retirement in 2012. As part of the forum, Mission Success Is in Our Hands will present the Golden Eagle Award to a Marshall team member. The award promotes awareness and appreciation for flight safety, as demonstrated through the connections between employees’ everyday work, the success of NASA and Marshall’s missions, and the safety of NASA astronauts. The award recognizes individuals who have made significant contributions to flight safety and mission assurance above and beyond their normal work requirements. Management or peers can nominate any team member for the award. Honorees are typically recognized at quarterly Shared Experiences forums. Smith, a Media Fusion employee and the Marshall Star editor, supports the Marshall Office of Communications. › Back to Top NASA Science Aboard Intuitive Machines Continues Journey to Moon, Landing Coverage set for Feb. 22 After a successful launch Feb. 15, six NASA science instruments and technology demonstrations continue their journey to the Moon aboard Intuitive Machines’ lander named Odysseus. The company confirmed communications contact with its mission operations control in Houston, and its lander continues to perform as expected. As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Intuitive Machines is targeting no earlier than 4:49 p.m. CST on Feb. 22 to land their Odysseus lunar lander near Malapert A in the South Pole region of the Moon. A view of Earth and one of Odysseus’ fuel pressurant tanks aboard the IM-1 mission. Intuitive Machines is a commercial company that has been contracted by NASA to send its science and technology instruments to the Moon. Columbia Sportswear is a commercial payload contracted with Intuitive Machines.Intuitive Machines Live landing coverage will air on NASA+, NASA Television, the NASA app, and the agency’s website. NASA TV can be streamed on a variety of platforms, including social media. Coverage will include live streaming and blog updates beginning 3:15 p.m., as the landing milestones occur. Upon successful landing, Intuitive Machines and NASA will host a news conference to discuss the mission and science opportunities that lie ahead as the company begins lunar surface operations. Known as IM-1, Intuitive Machines successfully transmitted its first images back to Earth on Feb. 16. These were captured shortly after separation from SpaceX’s second stage, on Intuitive Machines’ first journey to the Moon. Within an hour of launching, NASA confirmed data was streaming from the agency’s powered science and technology instruments aboard the flight. This means data from these instruments was automatically streaming back to the teams so NASA could monitor the health and status of its instruments. Later, Intuitive Machines successfully commissioned Odysseus’ engine which means they exercised the engine’s complete flight profile, including the throttling required for landing. The engine, which uses liquid methane and liquid oxygen, is the first of its kind fired in space. One of the NASA instruments, the Radio Frequency Mass Gauge is gauging the cryogenic propellants on Odysseus throughout the mission. Data files have been collected and many have been downloaded for analysis. Throughout the propellant loading phase that took place before launch, the instrument collected data, which was downloaded and analyzed in near-real time. Data also is being collected during the microgravity transit phase of the mission. This analysis will continue through landing on the Moon. Another NASA instrument, Lunar Node-1, or LN-1, integrates navigation and communication . LN-1 was developed, built, and tested at NASA’s Marshall Space Flight Center. This science instrument will operate daily during the cruise phase as the landing date draws closer. The radio beacon is designed to support precise geolocation and navigation observations to orbiters, landers, and surface personnel, digitally confirming their positions on the Moon relative to other craft, ground stations, or rovers on the move. The check-out helps prepare to land on the Moon as the navigation demonstrator aims to gather this data throughout the duration of the surface operations phase of the mission. Flight controllers will analyze the data from this procedure to inform preparations for landing Feb. 22. Follow the Artemis blog for updates, or follow along with Intuitive Machines for the latest operational updates on their mission. › Back to Top Rocket Propellant Tanks for NASA’s Artemis III Mission Take Shape With the liquid oxygen tank now fully welded, all the major structures that will form the core stage for NASA’s SLS (Space Launch System) rocket for the agency’s Artemis III mission are ready for additional outfitting. The hardware will be a part of the rocket used for the first of the Artemis missions planning to land astronauts on the Moon’s surface near the lunar South Pole. Technicians finished welding the 51-foot liquid oxygen tank structure inside the Vertical Assembly Building at NASA’s Michoud Assembly Facility on Jan. 8. All the major structures that will form the core stage for NASA’s SLS (Space Launch System) rocket for the agency’s Artemis III mission are structurally complete. Technicians finished welding the 51-foot liquid oxygen tank structure, left, inside the Vertical Assembly Building at NASA’s Michoud Assembly Facility on Jan. 8. The liquid hydrogen tank, right, completed internal cleaning Nov. 14.NASA/Michael DeMocker The mega rocket’s other giant propellant tank – the liquid hydrogen tank – is already one fully welded structure. NASA and Boeing, the SLS core stage lead contractor, are currently priming the tank in another cell within the Vertical Assembly Building area called the Building 131 cryogenic tank thermal protection system and primer application complex. It completed internal cleaning Nov. 14. Manufacturing hardware is a multi-step process that includes welding, washing, and, later, outfitting hardware. The internal cleaning process is similar to a shower to ensure contaminants do not find their way into the stage’s complex propulsion and engine systems prior to priming. Once internal cleaning is complete, primer is applied to the external portions of the tank’s barrel section and domes by an automated robotic tool. Following primer, technicians apply a foam-based thermal protection system to shield it from the extreme temperatures it will face during launch and flight while also regulating the super-chilled propellant within. “NASA and its partners are processing major hardware elements at Michoud for several SLS rockets in parallel to support the agency’s Artemis campaign,” said Chad Bryant, acting manager of the Stages Office for NASA’s SLS Program. “With the Artemis II core stage nearing completion, the major structural elements of the SLS core stage for Artemis III will advance through production on the factory floor.” The two massive propellant tanks for the rocket collectively hold more than 733,000 gallons of super-chilled propellant. The propellant powers the four RS-25 engines and must stay extremely cold to remain liquid. The core stage, along with the RS-25 engines, will produce two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis III. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. Through Artemis, NASA will send astronauts – including the first woman, first person of color, and first international partner astronaut – to explore the Moon for scientific discovery, economic benefits, and to build the foundation for crewed mission to Mars. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, exploration ground systems, advanced spacesuits and rovers, Gateway, and human landing systems. NASA’s Marshall Space Flight Center manages the SLS Program and Michoud Assembly Facility. › Back to Top Artemis II Mission Manager: Matthew Ramsey Matthew Ramsey is keenly aware of the responsibility he shoulders to ensure NASA’s missions to the Moon are safe and successful. As the mission manager for Artemis II, NASA’s first crewed mission under Artemis, Ramsey is charged with helping to define the requirements and priorities for the missions and certifying that the hardware and operations needed to support flight are ready. “For me, it’s all about the crew and ensuring their safety as they venture to the Moon and come home,” Ramsey said. “Sending people thousands of miles from home and doing it in a way that sets the stage for long-term exploration and scientific discovery is an incredibly complex task.” Matthew Ramsey is the mission manager for Artemis II. During the Artemis I launch, Ramsey was the SLS Engineering Support Center manager at NASA’s Marshall Space Flight Center.NASA/Brandon Hancock During the leadup to Artemis II, Ramsey is responsible for oversight of the daily preparations as NASA prepares to launch and fly the agency’s SLS (Space Launch System) rocket with a crew of four inside the Orion spacecraft. He will adjudicate issues that arise in the weeks and months ahead of the flight test and serve as deputy of the Mission Management Team – a tiger team that forms two days before launch to accept the risks associated with the mission and make decisions during the flight to address any changes or concerns. A native of Hernando, Mississippi, Ramsey pitched for the Mississippi State University baseball team before earning bachelor’s and master’s degrees in aerospace engineering from the school. “There are a lot of similarities between mission management and pitching,” he said. “You control many aspects of the tempo, and there’s a lot of weight on your shoulders.” Ramsey began his career in the intelligence and defense sectors before joining the space agency in 2002 to work on guidance, navigation, and control for the X-37 Approach and Landing Test Vehicle. Later, he worked on the design of the Ares I and V rockets as part of NASA’s Constellation Program before transitioning in 2010 to the SLS Program in support of the chief engineer at the agency’s Marshall Space Flight Center. During the Artemis I launch, Ramsey was the SLS Engineering Support Center manager at Marshall, coordinating across engineering teams to provide data and solutions to issues encountered during the multiple launch attempts. He then supported the Mission Management Team during Artemis I in an observational role, preparing for his position as Artemis II mission manager. While NASA and its partners are preparing for Artemis II, work toward other Artemis missions is also underway. Ramsey also will serve as the mission manager for Artemis IV, the first Gateway assembly mission that also will include a lunar landing. “With Artemis II on the horizon, most of my time is focused on making sure we’re ready to fly Reid, Victor, Christina, and Jeremy around the Moon and bring them safely home,” Ramsey said. “For Artemis IV, we’re in the mission concept-planning phase, establishing mission priorities and objectives and defining how we’ll transfer crew between all the hardware elements involved.” As Artemis II nears, Ramsey is blending his operational experience and expertise in design, development, testing, and evaluation so that NASA is primed for what lies ahead: sending humans back to the Moon for the first time in more than 50 years and laying the foundation for future missions that will ultimately enable human exploration of Mars. › Back to Top Teams Add Iconic NASA ‘Worm’ Logo to Artemis II Rocket, Spacecraft Art and science merged as teams added the NASA “worm” logo on the SLS (Space Launch System) solid rocket boosters and the Orion spacecraft’s crew module adapter at NASA’s Kennedy Space Center for the agency’s Artemis II mission. The iconic logo was introduced in 1975 by the firm of Danne & Blackburn as a modern emblem for the agency. It emerged from a nearly 30-year retirement in 2020 for limited use on select missions and products. Workers with NASA’s Exploration Ground Systems paint the bright red NASA “worm” logo on the side of an Artemis II solid rocket booster segment inside the Rotation, Processing and Surge Facility at the agency’s Kennedy Space Center on Jan. 30. The Exploration Ground Systems team used a laser projector to mask off the logo with tape, then painted the first coat of the iconic design.NASA/Glenn Benson NASA’s Exploration Ground Systems and prime contractor Jacobs began painting the red logotype onto the segments that form the Moon rocket’s two solid rocket boosters Jan. 22. To do so, crews used a laser projector to first mark off the location of the logo with tape, then applied two coats of paint and finished by adding several coats of clear primer. Each letter of the worm logo measures approximately 6 feet and 10 inches in height and altogether, stretches 25 feet from end to end, or a little less than the length of one of the rocket’s booster motor segments. The location of the worm logo will be moderately different from where it was during Artemis I. While it will still be located on each of the rocket’s 17 story boosters, the modernist logo will be placed toward the front of the booster systems tunnel cover. The SLS boosters are the largest, most powerful solid propellant boosters ever flown and provide more than 75% of the thrust at launch. The Orion spacecraft for NASA’s Artemis II mission received its latest makeover Jan. 28. Teams adhered the agency’s iconic “worm” logo and ESA (European Space Agency) insignia on the spacecraft’s crew module adapter inside the Neil Armstrong Operations and Checkout Building at Kennedy.NASA/Rad Sinyak Around the corner inside the Neil Armstrong Operations and Checkout Building at Kennedy, personnel adhered the worm logo and ESA (European Space Agency) insignia Jan. 28 on the spacecraft’s crew module adapter. The adapter houses electronic equipment for communications, power, and control, and includes an umbilical connector that bridges the electrical, data, and fluid systems between the main modules. In October 2023, technicians joined the crew and service modules together. The crew module will house the four astronauts as they journey around the Moon and back to Earth on an approximately 10-day journey. The spacecraft’s service module, provided by ESA, will supply the vehicle with electricity, propulsion, thermal control, air, and water in space. NASA is working to land the first woman, first person of color, and first international partner astronaut on the Moon through Artemis. SLS and the Orion spacecraft are central to NASA’s deep space exploration plans, along with advanced spacesuits and rovers, the Gateway space station planned for orbit around the Moon, and commercial human landing systems. NASA’s Marshall Space Flight Center manages the SLS Program. › Back to Top Chandra: Black Hole Fashions Stellar Beads on A String Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded in the system known as SDSS J1531+3414 (SDSS J1531 for short). This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling “beads on a string.” SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark matter. At the center of SDSS J1531, which is located about 3.8 billion light-years away, two of the cluster’s largest galaxies are colliding with each other. SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark matter. In the heart of SDSS J1531, two of the cluster’s largest galaxies are colliding with each other. Surrounding these merging giants is a set of 19 large clusters of stars, called superclusters, arranged in an ‘S’ formation that resembles beads on a string.X-ray: NASA/CXC/SAO/O. Omoruyi et al.; Optical: NASA/ESA/STScI/G. Tremblay et al.; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers used several telescopes to study SDSS J1531 including NASA’s Chandra X-ray Observatory, and LOFAR (Low Frequency Array), a radio telescope. A composite image shows SDSS J1531 in X-rays from Chandra (blue and purple) that have been combined with radio data from LOFAR (dark pink) as well as an optical image from the Hubble Space Telescope (appearing as yellow and white). The inset gives a close-in view of the center of SDSS J1531 in optical light, showing the two large galaxies and a set of 19 large clusters of stars, called superclusters, stretching across the middle. The image shows these star clusters are arranged in an ‘S’ formation that resembles beads on a string. The multiwavelength data provides signs of an ancient, titanic eruption in SDSS J1531, which a team of researchers think was responsible for creation of the 19 star clusters. Their argument is that an extremely powerful jet from the supermassive black holes in the center of one of the large galaxies pushed the surrounding hot gas away from the black hole, creating a gigantic cavity. The evidence for a cavity comes from “wings” of bright X-ray emission, seen with Chandra, tracing dense gas near the center of SDSS J1531. These wings are the edge of the cavity and the less dense gas in between is part of the cavity. LOFAR shows radio waves from the remains of the jet’s energetic particles filling in the giant cavity. These features are highlighted in a labeled version of the image. A labeled version of SDSS J1531.X-ray: NASA/CXC/SAO/O. Omoruyi et al.; Optical: NASA/ESA/STScI/G. Tremblay et al.; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk The astronomers also discovered cold and warm gas located near the opening of the cavity, detected with the Atacama Large Millimeter and submillimeter Array and the Gemini North Telescope, respectively. A separate graphic shows the optical image with the cold gas added in green (left), and the warm gas added in red (right). The team argues that some of the hot gas pushed away from the black hole eventually cooled to form the cold and warm gas shown. The team thinks tidal effects from the two merging galaxies compressed the gas along curved paths, leading to the star clusters forming in the “beads on a string” pattern.

Speeding through the outer edges of the Kuiper Belt, almost 60 times farther from the Sun than Earth, the New Horizons SDC (Venetia Burney Student Dust Counter) instrument is detecting higher than expected levels of dust – the tiny frozen remnants of collisions between larger Kuiper Belt objects, or KBOs, and particles kicked up from KBOs being peppered by microscopic dust impactors from outside of the solar system. Artist’s concept of a collision between two objects in the distant Kuiper Belt. Such collisions are a major source of dust in the belt, along with particles kicked up from Kuiper Belt objects being peppered by microscopic dust impactors from outside of the solar system.Credit: Dan Durda, FIAAA The readings defy scientific models that the KBO population and density of dust should start to decline a billion miles inside that distance and contribute to a growing body of evidence that suggests the outer edge of the main Kuiper Belt could extend billions of miles farther than current estimates – or that there could even be a second belt beyond the one we already know. The results appear in the Feb. 1 issue of the Astrophysical Journal Letters. “New Horizons is making the first direct measurements of interplanetary dust far beyond Neptune and Pluto, so every observation could lead to a discovery,” said Alex Doner, lead author of the paper and a physics graduate student at the University of Colorado Boulder who serves as SDC lead. “The idea that we might have detected an extended Kuiper Belt – with a whole new population of objects colliding and producing more dust – offers another clue in solving the mysteries of the solar system’s most distant regions.” Designed and built by students at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder under the guidance of professional engineers, SDC has detected microscopic dust grains produced by collisions among asteroids, comets and Kuiper Belt objects all along New Horizons’ 5-billion-mile, 18-year journey across our solar system – which after launch in 2006 included historic flybys of Pluto in 2015 and the KBO Arrokoth in 2019. The first science instrument on a NASA planetary mission to be designed, built and “flown” by students, the SDC counts and measures the sizes of dust particles, producing information on the collision rates of such bodies in the outer solar system. The latest, surprising results were compiled over three years as New Horizons traveled from 45 to 55 AU (astronomical units from the Sun – with one AU being the distance between Earth and Sun, about 93 million miles. These readings come as New Horizons scientists, using observatories like the Japanese Subaru Telescope in Hawaii, have also discovered a number KBOs far beyond the traditional outer edge of the Kuiper Belt. This outer edge (where the density of objects starts to decline) was thought to be at about 50 AU, but new evidence suggests the belt may extend to 80 AU, or farther. As telescope observations continue, Doner said, scientists are looking at other possible reasons for the high SDC dust readings. One possibility, perhaps less likely, is radiation pressure and other factors pushing dust created in the inner Kuiper Belt out past 50 AU. New Horizons could also have encountered shorter-lived ice particles that cannot reach the inner parts of the solar system and were not yet accounted for in the current models of the Kuiper Belt. “These new scientific results from New Horizons may be the first time that any spacecraft has discovered a new population of bodies in our solar system,” said Alan Stern, New Horizons principal investigator from the Southwest Research Institute in Boulder. “I can’t wait to see how much farther out these elevated Kuiper Belt dust levels go.” Now into its second extended mission, New Horizons is expected to have sufficient propellant and power to operate through the 2040s, at distances beyond 100 AU from the Sun. That far out, mission scientists say, the SDC could potentially even record the spacecraft’s transition into a region where interstellar particles dominate the dust environment. With complementary telescopic observations of the Kuiper Belt from Earth, New Horizons, as the only spacecraft operating in and collecting new information about the Kuiper Belt, has a unique opportunity to learn more about KBOs, dust sources and expanse of the belt, and interstellar dust and the dust disks around other stars. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built and operates the New Horizons spacecraft and manages the mission for NASA’s Science Mission Directorate. Southwest Research Institute, based in San Antonio and Boulder, Colorado, directs the mission via Principal Investigator Alan Stern and leads the science team, payload operations and encounter science planning. New Horizons is part of NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center. › Back to Top View the full article

Galaxy cluster SDSS J1531+3414X-ray: NASA/CXC/SAO/O. Omoruyi et al.; Optical: NASA/ESA/STScI/G. Tremblay et al.; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded in the system known as SDSS J1531+3414 (SDSS J1531 for short). As explained in our press release, this mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling “beads on a string.” SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark matter. At the center of SDSS J1531, which is located about 3.8 billion light-years away, two of the cluster’s largest galaxies are colliding with each other. Astronomers used several telescopes to study SDSS J1531 including NASA’s Chandra X-ray Observatory, and the Low Frequency Array (LOFAR), a radio telescope. This composite image shows SDSS J1531 in X-rays from Chandra (blue and purple) that have been combined with radio data from LOFAR (dark pink) as well as an optical image from the Hubble Space Telescope (appearing as yellow and white). The inset gives a close-in view of the center of SDSS J1531 in optical light, showing the two large galaxies and a set of 19 large clusters of stars, called superclusters, stretching across the middle. The image shows these star clusters are arranged in an ‘S’ formation that resembles beads on a string. The multiwavelength data provides signs of an ancient, titanic eruption in SDSS J1531, which a team of researchers think was responsible for creation of the 19 star clusters. Their argument is that an extremely powerful jet from the supermassive black holes in the center of one of the large galaxies pushed the surrounding hot gas away from the black hole, creating a gigantic cavity. The evidence for a cavity comes from “wings” of bright X-ray emission, seen with Chandra, tracing dense gas near the center of SDSS J1531. These wings are the edge of the cavity and the less dense gas in between is part of the cavity. LOFAR shows radio waves from the remains of the jet’s energetic particles filling in the giant cavity. These features are highlighted in a labeled version of the image. Multiwavelength Image of SDSS J1531, LabeledX-ray: NASA/CXC/SAO/O. Omoruyi et al.; Optical: NASA/ESA/STScI/G. Tremblay et al.; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk The astronomers also discovered cold and warm gas located near the opening of the cavity, detected with the Atacama Large Millimeter and submillimeter Array (ALMA) and the Gemini North Telescope, respectively. A separate graphic shows the optical image with the cold gas added in green (left), and the warm gas added in red (right). The team argues that some of the hot gas pushed away from the black hole eventually cooled to form the cold and warm gas shown. The team thinks tidal effects from the two merging galaxies compressed the gas along curved paths, leading to the star clusters forming in the “beads on a string” pattern.

The overall scene resembles a colorful display of lights as if viewed through a wet, glass window. Blurry orange dots of different sizes are scattered across a black background. These orange dots are entire galaxies. Near the center of the image, two central galaxies appear as bright, white dots. Star clusters, resembling beads on a string in shades of electric blue, sweep over the galaxy on the left, through the space in between the galaxy pair, and then lightly coil beneath both galaxies. Clouds of blue, X-ray light, and dark pink, radio light, surround the two galaxies. The blue cloud spreads out for thousands of light-years toward the region above the central galaxies. The dark pink cloud, somewhat resembling the shape of an upside down spinning top toy, stretches far below the two galaxies and slightly toward our left. This dark pink cloud represents the remains of a powerful jet, produced by a supermassive black hole within one of the two central galaxies. In the upper right corner of the image, another dark pink cloud is present. This cloud may be the relic of a counter-jet from the same black hole outburst.

Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says collaborating with her teams is one of the best parts of her job.UC Santa Cruz, UC Regents Science is often portrayed as a solitary affair, where discoveries are made by lone geniuses toiling in isolation. But Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says solving problems with the people around her is one of the best parts of her job. “Oh, man, working with people is all I do!” said Batalha, whose current research involves using NASA’s James Webb Space Telescope to study exoplanets, planets outside our solar system that orbit other stars. Batalha’s work explores hot, Jupiter-like exoplanets; smaller, rocky exoplanets more similar to Earth; and brown dwarfs, mysterious objects smaller than a star but huge compared to the biggest planets. A single question has driven her since she was a kid: “Does life exist beyond Earth?” It’s a lofty question, bigger than any one scientist. And that’s the point. “I love being part of a larger community,” she said, “We’re working together to try to solve this question that people have been asking for centuries.” However, the particular joy of belonging wasn’t always present in Batalha’s life. When she was 10, her family moved from Brazil to the U.S., where she was met with culture shock, pressure to assimilate, and a language barrier. She thinks the latter is partly why she gravitated toward the universal language of math. Eventually, her interests and strengths took shape around astronomy. When she chose to study physics in college, followed by a dual PhD in astronomy and astrobiology, her parents – who are also scientists – helped fill in for the community she was otherwise lacking. “In high school, I watched female students drop out of my physics classes,” Batalha said. “The honors physics track in college was devoid of women and people of color. I didn’t feel I had a community in my college classes.” Her mother, Natalie Batalha, is an astronomer who served as project scientist for NASA’s Kepler space telescope– the mission that taught us there are more planets than stars. Natasha’s father is a LatinX physicist. Both her parents had already faced similar challenges in their careers, and having their example to look at of people who had successfully overcome those barriers helped her push on. “I identify as female and LatinX, which are both underrepresented groups in STEM,” she said, “but I also have a ton of privilege because my parents are in the field. That gave me a dual perspective on how powerful community is.” I love being part of a larger community. We’re working together to try to solve this question that people have been asking for centuries. Natasha Batalha NASA Astronomer Since then, empowering her own science community has been a focus of Batalha’s work. She builds open-source tools, like computer programs for interpreting data, that are available to all. They help scientists use Webb’s exoplanet data to study what climates they may have, the behavior of clouds in their atmospheres, and the chemistry at work there. “I saw how limiting closed toolsets could be for the community, when only an ‘inner circle’ had access to them,” Batalha said. “So, I wanted to create new tools that would put everyone on the same footing.” Batalha herself recently used Webb to explore the skies of exoplanet WASP-39 b, a hot gas giant orbiting a star 700 light-years away. She is part of the team that found carbon dioxide and sulfur dioxide there, marking the first time either was detected in an exoplanet atmosphere. Now, she is turning to the difficult-to-discern characteristics of smaller, cooler planets. Dr. Natasha Batalha has been hooked on the search for life beyond Earth since elementary school.UC Santa Cruz, UC Regents Batalha says she’s exactly where her 6th-grade self imagined she would be. In elementary school, she read a biography of NASA astronaut Sally Ride and was hooked by an idea it contained: that in 20 years the kids reading those words could be the ones pioneering the search for life on Mars. Today’s youth belong to the Artemis Generation, who will explore farther than people have ever gone before. The Artemis program will send the first woman and first person of color to the lunar surface. Missions over time will build a presence at the Moon to unlock a new era of science and prepare for human missions to Mars and beyond. Along the way, scientists will continue to search for signs of life beyond Earth, an endeavor building on the work of many generations and relying on those in the future to carry on the search. “That’s something really rewarding about my work at NASA,” she said. “These questions have been asked throughout human history and, by joining the effort to answer them, you’re taking the baton for a while, before passing it on to someone else.” View the full article

4 min read Ride the Wave of Radio Astronomy During the Solar Eclipse GAVRT DSS-28 dish at the NASA Deep Space Communications Complex near Goldstone, California. NASA/Russell Torres Students and science enthusiasts are invited to catch a real-time look at radio astronomy as scientists explore magnetic hotspots on the Sun during a live, virtual solar eclipse event on April 8, 2024. A massive, 34-meter telescope once used by NASA’s Deep Space Network to communicate with spacecraft will point towards the Sun during the solar eclipse that day. The Moon’s position in front of the Sun will help the antenna detect radio waves from solar active regions in more detail than is usually possible. The Solar Patrol team at California’s Lewis Center for Educational Research, in partnership with NASA’s Jet Propulsion Laboratory, will remotely operate the Goldstone Apple Valley Radio Telescope (GAVRT) while sharing observations and commentary during an interactive webinar open for the public. Scientists and students regularly use the single-dish GAVRT antenna, located in the Mojave Desert of California, to scan the Sun. They use the observations to build maps of radio waves formed along strong magnetic field lines in the outer atmosphere of the Sun. By studying these images, researchers can measure the strength and structure of those powerful magnetic regions. These observations offer insight into magnetically driven processes on the Sun, like solar flares and coronal mass ejections, which generate space weather events that can interfere with satellite electronics, radio communications and GPS signals, spacecraft orbits, and power grids on Earth. During normal solar observing, GAVRT can only detect and distinguish relatively large features on the Sun. A solar eclipse offers a unique opportunity for GAVRT to capture sharper and more refined information about the magnetic field structure in the solar active regions that are often marked by sunspots. “It’s special during the eclipse because, as the Moon is passing in front of an active region, that really sharp edge of the Moon covers up more and more of the structure in that active region,” says Marin Anderson, a research scientist at NASA’s Jet Propulsion Laboratory and GAVRT Solar Patrol scientist. Anderson explains how, as the Moon blocks a portion of the active region, it’s easier to tell what part of the active region the radio emissions are coming from. “It’s basically a way of probing magnetic field structures in the corona of the Sun in a way that we wouldn’t be able to unless an eclipse was happening.” Anyone in the world can join the live-streamed webinar on April 8 from 1-3:30 p.m. EDT (10 a.m. to 12:30 p.m. PDT) and ask the hosts questions as a partial eclipse becomes visible in California. Participants will be able to see the telescope controls, data visualization tools like Helioviewer, incoming radio data, a map of active hot spot regions, and imagery of the eclipsed Sun at radio wavelengths.

One of the active regions monitored by GAVRT during the eclipse is visible as the bright region in the lower left quadrant of the Sun. Click the arrow to see the eclipsed Sun. NASA/Thangasamy Velusamy GAVRT was awarded a NASA grant to carry out observations during both the 2023 and 2024 solar eclipses in the U.S. GAVRT supports an open science framework by making all data and radio maps available for viewing and downloading by the public. Images collected during the eclipse will be posted online with instructions on how to run software and analyze the data. The Solar Patrol team hopes the public webinar inspires people to become active members of the GAVRT program where they can learn to remotely operate the telescope themselves while taking part in data analysis and scientific discovery. “I think one of the really great aspects of GAVRT Solar Patrol is that it connects any participant, but particularly students, with the Sun, beyond what they see and experience every day from the star,” Anderson says. “It’s seeing the Sun at radio wavelengths and being able to connect different parts of the electromagnetic spectrum with unique physics that’s happening on the Sun.” Since its launch in 1997, GAVRT has offered many opportunities to combine science observations with education and outreach. In addition to Solar Patrol, GAVRT is used in campaigns where participants can study Jupiter’s radiation belts, monitor radio emissions from black holes, or search for extraterrestrial intelligence. Anderson says giving students the tools to do science themselves empowers them. “It’s a really hands-on process and I think the way to get kids excited and invested in not only solar science but the scientific process in general.” To register for the GAVRT April 8 eclipse livestream event, visit: https://register.gotowebinar.com/register/4920123655757293655 For other ways to get involved in GAVRT, including signing up a classroom to participate in observations, contact: mc@lcer.org or visit gavrt.lewiscenter.org.

NASA Administrator to Discuss Science With Crew Aboard Station

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This staged scene and illustration represents what you might see when NASA’s University Innovation project awards teams of students with funds to conduct real-world aeronautical research that will help the agency transform aviation for the 21st century. NASA /Lillian Gipson / Getty Images NASA has selected another five university teams to participate in real-world aviation research challenges that could help transform flight in the skies above our communities. Research topics range from safeguarding automated aircraft from cyberattacks to finding ways to help aircraft operations across the nation more quickly recover from delays due to major storms or technical problems. “The idea is to give students, faculty and their partners the chance to conduct research – both physical and digital – that helps us realize our vision for 21st century aviation that is sustainable and offers more diverse air travel options,” said Koushik Datta, University Innovation project manager for NASA’s Aeronautics Research Mission Directorate. The University Innovation project includes two efforts through which universities are invited to submit research proposals and from which teams are then selected: the University Leadership Initiative (ULI) and the University Student Research Challenge (USRC). A key ULI goal is for faculty-led student teams to gain experience by participating in aeronautics research on a multidisciplinary team made up of partners from other universities and industry, including faculty and student populations who are underrepresented or have not applied their skills to aviation problems. Meanwhile, in addition to conducting technical research, student-led USRC teams help them develop skills in entrepreneurship and public communication. Each team of students selected receives a USRC grant from NASA – and the additional challenge of raising funds from the public through student-led crowdfunding. ULI makes selections once a year, while USRC manages multiple selection cycles each year, with proposals for the next selection cycle due by 5 p.m. EDT on March 21. Visit the NASA Aeronautics Solicitations page for more information. For ULI, three teams were selected resulting in a total of $18 million in awards during the next three years. For each team, the proposing university will serve as lead. The new ULI selections are: University of California, Berkeley The team will test ideas for improving the ability of the National Airspace System to become more resilient to reduce the disruptive impact major storms, facility outages, and other technical issues can have on airline flight operations. Team members include University of Maryland, University of Michigan, Morgan State University, University of Pennsylvania, Elizabeth City State University, United Airlines, Patty Clark Aviation Advisors, ATAC Corporation, Mead and Hunt, American Airlines, Vaughan College of Aeronautics and Technology, The Federal Aviation Administration, Lansing Community College, Community College of Philadelphia, and City College of San Francisco. Ohio University The team will seek to solve technical challenges associated with the ability of large drones to safely taxi, take off, and land at airports using automated navigation systems. Team members include Illinois Institute of Technology, Virginia Polytechnic Institute and State University, Tufts University, Stanford University, Veth Research Associates LLC, Reliable Robotics Corporation, Boeing, and Virginia Tech Transportation Institute. The George Washington University The team will investigate measures that can be taken to safeguard autonomous aircraft flying in high-density urban airspace from cyberattacks that could disrupt safe operations. Team members include Vanderbilt University, Purdue University, Tennessee State University, University of California, Irvine, The University of Texas at Austin, Collins Aerospace, Northern Virginia Community College, Cyber Security and Privacy Research Institute at The George Washington University, Skygrid (a Boeing Company), and the Secure Resilient Systems and Technology Group at MIT Lincoln Laboratory. For USRC, NASA selected two new university student teams to participate in this cycle with a USRC grant that can be up to $80,000. The new USRC selections are: Cornell University The team’s project is titled “Learning Cooperative Policies for Adaptive Human-Drone Teaming in Shared Airspace” and will work to enable new coordination and communication models for smoother, more efficient and robust air traffic flow. The student team members are: Mehrnaz Sabet (lead), Aaron Babu, Marcus Lee, Joshua Park, Francis Pham, Owen Sorber, Roopak Srinivasan, and Austin Zhao. Faculty mentors are Sanjiban Choudhury and Susan Fussell. University of Washington, Seattle The team’s project is titled “Investigation on Cryogenic Fluid Chill-Down Time for Supersonic Transport Usage” and will investigate using vortex generators to reduce the boil-off of cryogenic fluids in pipes.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) When a physical condition limits mobility, getting around is easier with EyeGaze Edge. The eye-tracking technology integrates with the Ability Drive application used with motorized mobility devices, enabling hands-free control of a wheelchair’s motion. Credit: EyeGaze Inc. Communicating when a traumatic brain injury, stroke, or disease has made speech impossible can be daunting. Specialized eye-tracking technology uses eye movement to enable people living with disabilities to connect one-on-one, over the phone, or via the internet. Eye-tracking systems for computers pinpoint a person’s gaze – where the eye is looking at a screen – by reflecting infrared light off the cornea and capturing it with a camera, using image-processing software to determine the eye’s orientation. The technology isn’t new, but it has become much more widely accessible, thanks in part to a collaboration between NASA’s Jet Propulsion Laboratory in Southern California and a Fairfax, Virginia-based company called Eyegaze Inc. When the company built the first model in 1988, its computers were bulky, requiring three shipping boxes for equipment and a company staff member to set up the system. That cost limited access, and the learning process could be intimidating. In 1998, NASA and Eyegaze entered a public-private partnership via Congressional funding to make the hardware smaller, more portable, and affordable without compromising efficiency. It also reduced the weight of the original system by six times and its volume by nearly the same factor. Other advancements served as a springboard for two more decades of development. By collaborating with JPL, the two entities were able to miniaturize and improve the company’s Eyegaze Edge system and lower costs, eliminating barriers to ownership of this communications technology. “Working with NASA, we were able to make the device less bulky,” said Preethi Vaidyanathan, an engineer with Eyegaze. “Since then, we integrated the external components into a small camera.” It mounts above or below a standard computer screen and requires less than 15 seconds to calibrate to an individual’s gaze. Visual Surfing Minesweeper and other video games adapted to use eye-tracking technology are just one form of entertainment made possible by EyeGaze for people living with disabilities.Credit: EyeGaze Inc. As personal electronic devices and internet access became commonplace, Eyegaze customers wanted to do more than type. The company’s work with NASA and other government partners put it in a position to meet that demand. Eyeworld integrates with computers, mobile phones, and tablets, allowing the Eyegaze camera to function as an external mouse and keyboard. By enabling almost any computer function, it lets users chat online, post to social media, send emails, text, or make phone calls. It’s also possible to change room lighting, adjust thermostat settings, and operate other environmental controls using Amazon Echo and Google Home via pages of specialized buttons with one-glance button controls. During the COVID-19 pandemic, Eyegaze integrated communications programs such as Zoom and WhatsApp to allow people to connect with their family and friends. To help combat a sense of isolation, the company added meditation apps and Window Swap, which stream the views from different windows worldwide. Virtual museums take the viewer on guided tours. A music streaming service syncs to favorite music apps and offers the International Radio Garden app to sample music from other cultures. Access to online gaming communities provides another way to connect. “We are constantly thinking about what the customers want. One thing is freedom of movement, so controlling a wheelchair gives them that to some extent,” said Vaidyanathan. Eyegaze Edge integrates with the Ability Drive application used with motorized mobility devices. Looking at a specific button enables hands-free control of a wheelchair’s motion. The Right to Speak Eye-tracking hardware and software make it possible for a person to communicate using the movement of their eyes. This keyboard screen is one of many Eyegaze developed for people with a full range of eye motion. A vertical keyboard is available for those who can only look up and down. Credit: EyeGaze Inc. Numerous medical conditions can lead to the kind of physical paralysis making it impossible to speak. Well-publicized brain and spinal cord injuries in athletes have led to broader awareness. But there are a host of other causes, such as cerebral palsy, ALS, multiple sclerosis, muscular dystrophy, and spinal muscular atrophy. These conditions can result in locked-in syndrome, which paralyzes all voluntary muscles except those that control eye movement. Eye-tracking software is a lifeline for patients, using what may be their only remaining voluntary movement, but even that can be impeded. Eyegaze Edge measures several eye features, making it possible for the tracker to work even when less of the pupil is visible. The company employs clinical specialists who can troubleshoot issues that may prevent customers from using the system, eye conditions like cataracts, dry eyes, and eyelids that droop, partly covering the pupil. The company now serves individuals in 44 countries, including nations in Southeast Asia and Africa. Adults, children as young as 18 months old, military veterans, and others can communicate using only their eyes. If only vertical eye movement is possible, Eyegaze Edge offers a special vertical keyboard screen. Pages of commonly used phrases communicate a statement with a single glance. Large, easy-to-use buttons allow patients to communicate directly with healthcare providers and caregivers for everyday needs. Clinicians use Eyegaze Edge and teach their patients how to communicate using the technology. In some cases, Vaidyanathan said, this technology even allows people to share their final thoughts with family and friends. “NASA helped us get our technology to the size of a laptop – small and sleek. But we continue to investigate and design our solutions to meet ongoing needs. Communication is a key right, so we must accommodate these different challenges,” she said. NASA has a long history of transferring technology to the private sector. The agency’s Spinoff publication profiles NASA technologies that have transformed into commercial products and services, demonstrating the broader benefits of America’s investment in its space program.

After 25 years of international collaboration operating the largest and most technologically advanced laboratory in low Earth orbit, the current decade of research results has seen thousands of researchers around the world completing their investigations, analyzing their data, and publishing their findings. Through close examination of station client feedback obtained since 2002, station program managers, administration personnel, and technical staff have improved their processes and software tools to enhance communication with research teams for better in-flight data collection and sample return. These refinements affect experiment results and the conclusions researchers draw. The enhanced planning and coordination of investigation launch, stowage, crew time allocation, accessibility to station’s research capabilities (i.e., facilities), and data delivery are critical to the effective operation of scientific projects for accurate results to be shared with the scientific community, sponsors, legislators, and the public. Over 3,700 investigations have operated since Expedition 1, with more than 250 active research facilities, the participation of more than 100 countries, the work of more than 5,000 researchers, and over 4,000 publications. The growth in research (Figure 1) and international collaboration (Figure 2) has prompted the publication of over 560 research articles in top-tier scientific journals with about 75 percent of those groundbreaking studies occurring since 2018 (Figure 3). Figure 1 . Bibliometric mapping of station research growth over time. Count of the keyword microgravity co-occurring at least five times with other research keywords at different time periods.

Count of publications reported in journals ranked in the top 100 according to global standards of Clarivate. A total of 567 top-tier publications through the end of FY-23 are shown by year and research category. In this year’s edition of the Annual Highlights of Results, we report findings from a wide range of topics in biology and biotechnology, physics, human research, Earth and space science, and technology development – including investigations about plant root orientation, tissue damage and repair, bubbles, lightning, fire dynamics, neutron stars, cosmic ray nuclei, imaging technology improvements, brain and vascular health, solar panel materials, grain flow, as well as satellite and robot control. The findings highlighted here are only a small sample representative of the research conducted by all the participating space agencies – ASI (Agenzia Spaziale Italiana), CSA (Canadian Space Agency), ESA (European Space Agency), JAXA (Japanese Aerospace Exploration Agency), Roscosmos, and NASA – on station in the past 12 months. Many more studies in fiscal year (FY)-23 revealed remarkable results, such as finding reduced fat accumulation in the bone marrow (MARROW), identifying gene mutations that preserve muscle (Molecular Muscle), improving optical beams…detecting bacterial antibiotic resistance during spaceflight (Plazmida), observing abnormal cell division of human neural stem cells (STaARS Bioscience-4), among others. A full list of all the publications collected in FY-23 can be found at the end of this report. A publicly accessible database of space station investigations and publications can be found in the Space Station Research Explorer (SSRE) website, and all editions of the Annual Highlights of Results from the International Space Station can be found through the Past Annual Highlights of Results from the Space Station Research Results Library. Between Oct. 1, 2022, and Sept. 30, 2023, we identified a total of 330 articles associated with station research. Of these 330 articles, 268 appeared in peer-reviewed journals, 59 in conference proceedings, and 3 in gray literature such as books, magazines, technical reports, or patents. Articles are also categorized based on how authors obtained their results. There were 204 publications that reported direct implementation of the science aboard station (i.e., Results), 37 that reported development of the payload prior to operation on station (i.e., Flight Preparation), and 89 that emerged as follow-ups to station science (i.e., Derived). Because derived articles are new scientific studies generated from shared data, derived science is an additional return on the investment trusted to station science. For FY-23, this return on investment was 27 percent. Full definitions of these publication types (i.e, Results, Flight Preparation, and Derived) categories can be found on page 10 of this report. Figure 4. Count of publications by agency and station research category. A total of 330 articles were collected in FY-23. Figure 4 shows a stacked chart with the count of articles collected in FY-23 broken out by space agency and research category. In summary, we found three articles for CSA, 43 articles for ESA, 58 articles for JAXA, 10 articles for Roscosmos, and 216 articles for NASA. Of the 330 articles collected in FY-23, 66 were articles published prior to Oct. 1, 2022. Measuring Space Station Impacts The significant impact of sustained international multidisciplinary research in microgravity can be observed through the findings published in world-class scientific journals that adhere to a rigorous scientific peer-review process. With the assistance of Clarivate, a global database that collects publication and journal information for annual journal ranking and metrics, we identified the top findings produced by station researchers. One parameter, the journal’s Eigenfactor Score2, ranks each journal based on readership and influence, including the different citation standards of each discipline. From Oct 1, 2022, to Sept 30, 2023, 78 articles appeared in top-tier journals. Of those 78 articles, 26 were reported in top 20 journals (see Table 1). Table 1. A total of 78 articles were published in top-tier journals in FY-23: 21 articles in top 20 (green) and 57 articles in top 100 (yellow). Data ranked according to Clarivate Journal Citations Reports (JCR) Eigenfactor score. In addition to the research diversity and top-tier results obtained from station, a comparison of station science to global and US standards of category-normalized citation impact (i.e., adjusted impact of a publication based on its research area) shows greater influence of station science since 2010 compared to other research endeavors taking place domestically or internationally. The authority of station research was particularly prominent in 2019, and it continues to hold its place in the scientific community to date. Figure 5 illustrates this important comparison. Figure 5. Citation impact (normalized by research area) of station science publications compared to national and global standards. The high impact of space station is in great part attributed to the researchers who conduct transformative science in low Earth orbit. As shown in Table 2, four studies published in FY-23 have already received much acclaim from others in their field. Table 2. List of articles published in FY-23 that have been widely recognized in a short period of time. *NICER reported two additional FY-23 publications with over 10 citations. Advancements in technology and research on station have inspired students all over the world to pursue STEM careers, encouraged researchers to explore bold questions, and incentivized economies through the initiation of businesses in the space industry. While some of the most decisive steps toward space commercialization are recent, researchers from small and large companies, academic institutions, and government agencies have been conducting experiments in space since 2005 through the International Space Station National Lab. Today, the hard work is paying off. In FY-23, we collected 39 publications from investigations sponsored by National Lab with fascinating results in droplet behavior for the improvement of condensing systems (Drop Vibration), the reliable use of a genome examination and editing tool (Ax-1 CRSPR), the identification of specific gut bacteria involved in bone loss (Rodent Research-5), the use of neural networks for improved image analysis (Spaceborne Computer-2), and much more. In addition to the accomplishments of the International Partners and NASA on space station, National Lab’s alternative route to send investigations to space have demonstrated that new paths can be explored to expand research in microgravity for the advancement of science and benefit of humanity. Evolution of Space Station Results The archive of space station investigations went online in 2004. Since that time, changes to methods for tracking investigations and publications have been implemented, including increased differentiation between research disciplines and a re-characterization of publication fields. Currently, the following publication types are included in the Program Science Toolbox: Flight Preparation Results – publications about the development work performed for an investigation, facility, or project prior to operation on space station. Station Results – publications that provide information about the performance and results of an investigation, facility, or project as a direct implementation on station or on a vehicle to space station. Derived Results – publications that use data from an investigation that operated on station, but the authors of the article are not members of the original investigation team. Derived Results articles have emerged as a direct outcome of the open-source data initiative, which gives access to raw data for new researchers to analyze and publish innovative results, expanding global knowledge and scientific benefits. Patents – applications filed based on the performance and results of an investigation, facility, or project on station, or on a vehicle to space station. Related – publications that lead to the development of an investigation, facility, or project. Linking Space Station Benefits Space station research results lead to benefits for human exploration of space, benefits to humanity, and the advancement of scientific discovery. This year’s Annual Highlights of Results from the International Space Station includes descriptions of just a few of the results that were published from across the space station partnership during the past year. Space station investigation results have yielded updated insights into how to live and work more effectively in space by addressing such topics as understanding radiation effects on crew health, combating bone and muscle loss, improving designs of systems that handle fluids in microgravity, and determining how to maintain environmental control efficiently. Results from the space station provide new contributions to the body of scientific knowledge in the physical sciences, life sciences, and Earth and space sciences to advance scientific discoveries in multi-disciplinary ways. Space station science results have Earth-based applications, including understanding our climate, contributing to the treatment of disease, improving existing materials, and inspiring the future generation of scientists, clinicians, technologists, engineers, mathematicians, artists, and explorers.
