The four tethered flights on Astrobotic’s Xodiac rocket-powered lander took place in Mojave, California, from Sept. 12 through Oct. 4, 2023. Researchers tested the Ejecta STORM technology’s integration with a lander and operation in flight conditions that simulated the plume effects of a lunar lander. Credits: Astrobotic A research team from the University of Central Florida recently tested an instrument designed to measure the size and speed of surface particles kicked up by the exhaust from a rocket-powered lander on the Moon or Mars. Supported by NASA’s Flight Opportunities program, researchers evaluated the instrument in a series of flight tests on Astrobotic’s Xodiac rocket-powered lander in Mojave, California. When spacecraft land on the Moon or Mars, the rocket exhaust plume creates regolith ejecta – abrasive dust and large particles moving at high speeds – that can damage the lander and surrounding structures. Understanding how a rocket engine’s exhaust affects this ejecta will help mission designers plan more effectively for lunar landings by allowing them to model the soil erosion rate, the particle size distribution, and the velocities associated with plume-surface interaction. Researchers at the University of Central Florida developed the laser-based instrument, named Ejecta STORM (Sheet Tracking, Opacity, and Regolith Maturity), to answer this need while embracing the Flight Opportunities program’s “fly, fix, fly” ethos to quickly advance the technology. Four tethered flights enabled researchers to test the system’s integration with a lander and operation in flight conditions that simulated the plume effects of a lunar lander. These tests build on data collected during a 2020 flight campaign leveraging Xodiac. These 2020 flight tests, funded by the program’s TechFlights solicitation, allowed researchers to measure the density and size of particles during terrestrial simulations of lunar landings. Researchers expect the technology to inform model development and reduce risk for future lunar landings, ultimately improving mission design for rover-based planetary science missions, crewed missions to the Moon and other bodies, and in-situ resource utilization. Flight Opportunities is managed at NASA’s Armstrong Flight Research Center in Edwards, California, and is part of the agency’s Space Technology Mission Directorate.

As NASA explores, innovates, and inspires through its work, agency inventions aimed at monitoring atmospheric pollution, studying samples from asteroids, extracting oxygen from the Martian atmosphere, and revolutionizing flight have been named TIME’s Inventions of 2023. TIME announced the honorees on Oct. 24. “For more than 65 years, NASA has innovated for the benefit of humanity,” said NASA Administrator Bill Nelson. “From turning carbon dioxide to oxygen on Mars, to delivering the largest asteroid sample to Earth, helping improve air quality across North America, and changing the way we fly, our MOXIE, TEMPO, OSIRIS-REx and X-59 Quesst missions are proof that NASA turns science fiction into science fact. It’s all made possible by our world-class workforce who, time after time, show us nothing is beyond our reach when we work together.” Improving Air Quality Data NASA graphic showing basic path of TEMPO scanning. Image Credit: NASA NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission is the first space-based instrument to measure pollution hourly during the daytime across North America, spanning from Mexico City to Northern Canada and coast-to-coast. Launched in April 2023, TEMPO provides unprecedented daytime measurement and monitoring of major air pollutants. The first-of-its-kind instrument can monitor pollution within a four-square-mile area and is helping climate scientists improve life on Earth by providing openly accessible air quality data for studies of rush hour pollution, the transport of pollution from forest fires and volcanoes, and even the effects of fertilizers, and it also has the potential to help improve air quality alerts. Making Oxygen on Mars Technicians lower the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument into the belly of the Perseverance rover. Photo credit: NASA/JPL-CalTech In September, a microwave-size device known as MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment) aboard NASA’s Perseverance rover generated oxygen from the Martian atmosphere for the 16th and final time. Extracting oxygen from the atmospheric resources found on Mars via In-situ Resource Utilization processes will be critical to long-term human exploration of the Red Planet, providing explorers with breathable air and rocket propellant. Since Perseverance landed in 2021, MOXIE has proven far more successful than expected, generating more than 130 grams of oxygen, including 9.8 grams on its final run. At its most efficient, MOXIE produced 12 grams of oxygen an hour – twice as much as NASA’s original goals for the instrument – at least 98% purity.

Photo Credit: NASA/Keegan Barber On Sept. 24, NASA’s OSIRIS-REx mission returned a sample from asteroid Bennu to Earth. The sample is the first asteroid collected in space by NASA, and the largest ever collected from an asteroid. The rock and dust represent relics of our early solar system and could shed light on the origins of life. Early analysis of the sample at NASA’s Johnson Space Center in Houston has revealed high carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock. The Bennu sample will be divided and shared with partner space agencies and other institutions, providing generations of scientists a window about 4.5 billion years into the past. Quiet Sonic Thumps The X-59 Quesst aircraft is rolled out at Lockheed Martin’s facility in Palmdale, California. Photo credit: Lockheed Martin NASA’s X-59 experimental aircraft, the agency’s first purpose-built, supersonic X-plane in decades, is currently scheduled to take to the skies in 2024. The centerpiece of NASA’s Quesst mission, the agency will fly the X-59 to demonstrate the ability to fly faster than the speed of sound while reducing the typically loud sonic boom to a quieter “sonic thump”. NASA will use the X-59 to provide data to help regulators amend current rules that ban commercial supersonic flight over land, opening the door to greatly reduced flight times. NASA will fly the X-59 over several U.S. cities in the final phase of the mission, gathering public input to the hushed sonic thumps. The TEMPO instrument is managed by NASA Langley’s Science Directorate in collaboration with the Smithsonian Astrophysical Observatory. It was built by Ball Aerospace and integrated onto Intelsat 40E by Maxar. The MOXIE experiment was built Massachusetts Institute of Technology (MIT), and NASA’s Jet Propulsion Laboratory manages the project for the agency’s Space Technology Mission Directorate. The OSIRIS-REx mission, launched on Sept. 8, 2016, was led by the University of Arizona. It is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, under the agency’s Science Mission Directorate’s New Frontiers Program. The Low-Boom Flight Demonstration project is managed by NASA’s Armstrong Flight Research Center in Edwards, California, the X-59 Quesst is managed by NASA’s Langley Research Center in Hampton, Virginia, and both efforts are led by NASA’s Aeronautics Research Mission Directorate.

NASA Kennedy Space Center’s Katherine Cook, fourth from the left, attends a welcome reception for the 26th class of Mansfield Scholars at the Iikura House in Japan on Sept. 1, 2022. The reception was jointly hosted by the Ministry of Foreign Affairs of Japan, the Mansfield Foundation, and the National Personnel Authority of Japan.Contributed photo A yearlong journey of cultural and professional development overseas has a NASA Deep Space Logistics employee excited about current and future collaboration with one of America’s key international partners in the agency’s Artemis program. Katherine Cook, who develops cargo delivery services for NASA’s Gateway, recently returned to the agency’s Kennedy Space Center in Florida after an immersive experience in Japan. There, she collaborated with JAXA (Japan Aerospace Exploration Agency), government ministries contributing to Japan’s space activities, and The National Diet’s House of Representatives. Katherine Cook speaks at Kumamoto University Graduate School for Science and Technology in Japan on Dec. 16, 2022. The university is located on Kyushu, the southernmost main island of Japan.Contributed photo “Everything I did involved Artemis and human exploration,” Cook said. “Developing technologies for Moon to Mars is challenging, but if we can find a good balance of leveraging the strengths of each partner and continue to evolve the partnership, we’ll be able to share knowledge in an even more integrated way.” As part of her trip, Cook spent about five months at the Tsukuba Space Center, approximately one hour north of Tokyo, working under JAXA Vice President and Director General for Human Spaceflight Technology Hiroshi Sasaki. She partnered with JAXA subject matter experts to host themed discussions for the directorate team, sharing and discussing ideas about the U.S and Japanese approaches, including future partnering opportunities. Her research themes included: NASA’s Moon to Mars objectives; commercial capabilities such as commercial low Earth orbit development; lunar surface transportation such as rovers and utility vehicles; lunar in-situ resource utilization, human landing systems, and science priorities to enable human exploration to the Moon and beyond. This required intense language training – before and throughout Cook’s trip – so she could understand, write, and speak Japanese with an audience ranging from students and coworkers to Japanese dignitaries, such as the Minister of Foreign Affairs Yoshimasa Hayashi and JAXA President Dr. Hiroshi Yamakawa. On June 15, 2022, Koji Tomita (fourth from the left), ambassador extraordinary and plenipotentiary of Japan to the United States, hosts six members of the Mansfield Fellowship, including NASA’s Katherine Cook, fifth from the left, in Washington, D.C., before their departure to Japan.Contributed photo “I think a lot of growth came out of challenging myself – both in learning more about NASA and U.S. agencies collaborating on space and learning about it deeply enough to explain it and communicate it in a succinct way that could make it through translation,” Cook said. Cook was just the third NASA person selected in the nearly 30-year history of the Mansfield Fellowship, a program named for former U.S. Senate Majority Leader and U.S. Ambassador to Japan Mike Mansfield. Invited to lecture at several university graduate programs, Cook was inspired by students’ interest in NASA’s Moon to Mars plans, as well as their knowledge and in-depth questions. Her interaction with Japanese colleagues was equally positive, as they welcomed her to their group with open arms. During the Artemis I launch in November 2022, Cook invited members of the JAXA human spaceflight team to a launch viewing party. Aware that she was disappointed about missing the launch live, they blew her away by showing up in great numbers, doling out high-fives and ecstatically cheering on the launch in front of a big screen TV at the Tsukuba Space Center. After a ride on the new Superconducting Maglev, the world’s fastest bullet train that travels up to 311 mph and operates on a magnetic levitation railway system, Mansfield Fellows stop by a convenience store for a drinkable ice cream treat on May 18, 2023. NASA’s Katherine Cook is pictured third from the left.Contributed photo “One thing that leaves an impression on you from Japan is their hospitality. The word for it is ‘omotenashi,’” Cook said. “It’s more than just a word; it’s culturally ingrained in how they interact with each other and the level of consideration that they put into everything they do.” Enriched technically, culturally, and spiritually from her transformative experience in Japan, Cook returned to NASA “forever changed.” She learned a great deal about science, life, and her own agency. She even picked up a saying that she incorporated into her daily work routine. “In Japan, at the end of every day, you say, ‘Otsukaresama deshita,’ which means, ‘Thank you for your hard work.’ When you pass a coworker in the hall and when you toast in celebration with coworkers, you say ‘Otsukaresama des,’ ” Cook said. “Even still, when I meet with my Japanese counterparts, I will often say it. And it reminds me to carry that appreciation of my team throughout my day back at NASA. The simple phrase bonds us all together across the international Artemis work we do.” View the full article

6 min read NASA-ISRO Radar Mission to Provide Dynamic View of Forests, Wetlands NISAR will use radar to study changes in ecosystems around the world, such as this forest in Tikal National Park in northern Guatemala, to understand how these areas are affected by climate change and human activity, and the role they play in the global carbon cycle.Credit: USAID NISAR will help researchers explore how changes in Earth’s forest and wetland ecosystems are affecting the global carbon cycle and influencing climate change. Once it launches in early 2024, the NISAR radar satellite mission will offer detailed insights into two types of ecosystems – forests and wetlands – vital to naturally regulating the greenhouses gases in the atmosphere that are driving global climate change. NISAR is a joint mission by NASA and ISRO (Indian Space Research Organisation), and when in orbit, its sophisticated radar systems will scan nearly all of Earth’s land and ice surfaces twice every 12 days. The data it collects will help researchers understand two key functions of both ecosystem types: the capture and the release of carbon. Pictured in this artist’s concept, NISAR, short for NASA-ISRO Synthetic Aperture Radar, marks the first time the U.S. and Indian space agencies have cooperated on hardware development for an Earth-observing mission. Its two radar systems will monitor change in nearly all of Earth’s land and ice surfaces twice every 12 days.Credit: NASA/JPL-Caltech Forests hold carbon in the wood of their trees; wetlands store it in their layers of organic soil. Disruption of either system, whether gradual or sudden, can accelerate the release of carbon dioxide and methane into the atmosphere. Tracking these land-cover changes on a global scale will help researchers study the impacts on the carbon cycle – the processes by which carbon moves between the atmosphere, land, ocean, and living things. “The radar technology on NISAR will allow us to get a sweeping perspective of the planet in space and time,” said Paul Rosen, the NISAR project scientist at NASA’s Jet Propulsion Laboratory in Southern California. “It can give us a really reliable view of exactly how Earth’s land and ice are changing.” Tracking Deforestation Forestry and other land-use changes account for about 11% of net human-caused greenhouse gas emissions. NISAR’s data will improve our understanding of how the loss of forests around the world influences the carbon cycle and contributes to global warming. “Globally, we do not understand well the carbon sources and sinks from terrestrial ecosystems, particularly from forests,” said Anup Das, an ecosystems scientist and co-lead of the ISRO NISAR science team. “So we expect that NISAR will greatly help address that, especially in less dense forests, which are more vulnerable to deforestation and degradation.” To show the kind of imagery NISAR will produce, researchers pointed to this composite that uses data from two Japanese L-band SAR missions to reveal land-cover change in Brazil’s Xingu River basin between 1996 and 2007. Black shows forest areas converted to farmland before 1996, and red shows additional areas cleared by 2007.Credit: Woodwell Climate Research Center/Earth Big Data LLC. Data courtesy of METI and JAXA. The signal from NISAR’s L-band radar will penetrate the leaves and branches of forest canopies, bouncing off the tree trunks and the ground below. By analyzing the signal that reflects back, researchers will be able to estimate the density of forest cover in an area as small as a soccer field. With successive orbital passes, it will be able to track whether a section of forest has been thinned or cleared over time. The data – which will be collected in early morning and evening and in any weather – could also offer clues as to what caused the change, such as disease, human activity, or fire. It’s an important set of capabilities for studying vast, often cloud-covered rainforests such as those in the Congo and Amazon basins, which lose millions of wooded acres every year. Fire releases carbon into the air directly, while the deterioration of forests reduces the absorption of atmospheric carbon dioxide. The data could also help improve accounting of deforestation and forest degradation – as well as forest growth – as countries that rely on logging try to shift toward more sustainable practices, said Josef Kellndorfer, a member of the NISAR science team and founder of Earth Big Data LLC, a provider of large data sets and analytic tools for research and decisions support. “Reducing deforestation and degradation is low-hanging fruit to address a substantial part of the global carbon emission problem,” he added. Monitoring Wetland Flooding Wetlands present another carbon puzzle: Swamps, bogs, peatlands, inundated forests, marshes, and other wetlands hold 20 to 30% of the carbon in Earth’s soil, despite constituting only 5 to 8% of the land surface. When wetlands flood, bacteria go to work digesting organic matter (mostly dead plants) in the soil. Through this natural process, wetlands are the planet’s largest natural source of the potent greenhouse gas methane, which bubbles to the water’s surface and travels into the atmosphere. Meanwhile, when wetlands dry out, the carbon they store is exposed to oxygen, releasing carbon dioxide. NISAR will track wetland flooding to study how these carbon-rich ecosystems are reacting to climate change. It will generate images like this one from an airborne radar that flew over Peru in 2013. Black indicates water, gray is rainforest, green is low vegetation, and red and pink are flooded plants.Credit: NASA/JPL-Caltech “These are huge reservoirs of carbon that can be released in a relatively short time frame,” said Erika Podest, a NISAR science team member and a carbon cycle and ecosystems researcher at JPL. Less well understood is how changing temperature and precipitation patterns due to climate change – along with human activities such as development and agriculture – are affecting the extent, frequency, and duration of flooding in wetlands. NISAR will be able to monitor flooding, and with repeated passes, researchers will be able to track seasonal and annual variations in wetlands inundation, as well as long-term trends. By coupling NISAR’s wetlands observations with separate data on the release of greenhouse gases, researchers should gain insights that inform the management of wetland ecosystems, said Bruce Chapman, a NISAR science team member and JPL wetlands researcher. “We have to be careful to reduce our impact on wetland areas so that we don’t worsen the situation with the climate,” he added. NISAR is set to launch in early 2024 from southern India. In addition to tracking ecosystem changes, it will collect information on the motion of the land, helping researchers understand the dynamics of earthquakes, volcanic eruptions, landslides, and subsidence and uplift (when the surface sinks and rises). It will also track the movements and melting of both glaciers and sea ice. More About the Mission NISAR is an equal collaboration between NASA and ISRO and marks the first time the two agencies have cooperated on hardware development for an Earth-observing mission. JPL, which is managed for NASA by Caltech in Pasadena, leads the U.S. component of the project and is providing the mission’s L-band SAR. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. ISRO’s U R Rao Satellite Centre in Bengaluru, which is leading the ISRO component of the mission, is providing the spacecraft bus, the S-band SAR electronics, the launch vehicle, and associated launch services and satellite mission operations.

“Obviously, Spanish has a lot to do with accessibility and broadening our audiences. We are using Spanish as a tool to break those barriers to connect with audiences. Spanish is the language I grew up with in Uruguay, and the language that I feel more comfortable with. It is amazing that I get to use it as a bridge to communicate with our audiences on different platforms. “We want to inform, but we also want to inspire and tell the stories that go beyond the mission and science. We want to tell the personal stories in [‘Universo Curioso de la NASA,’ NASA’s first-ever Spanish podcast]. “We started as a bonus episode of a miniseries of an existing podcast, ‘NASA’s Curious Universe,’ but we wanted to build something that was unique, specifically tailored to the Hispanic audience in the U.S. and worldwide.

5 min read NASA Rocket to See Sizzling Edge of Star-Forming Supernova A new sounding rocket mission is headed to space to understand how explosive stellar deaths lay the groundwork for new star systems. The Integral Field Ultraviolet Spectroscopic Experiment, or INFUSE, sounding rocket mission, will launch from the White Sands Missile Range in New Mexico on Oct. 29, 2023, at 9:35 p.m. MDT. For a few months each year, the constellation Cygnus (Latin for “swan”) swoops through the northern hemisphere’s night sky. Just above its wing is a favorite target for backyard astronomers and professional scientists alike: the Cygnus Loop, also known as the Veil Nebula. This image shows an illustration of the constellation Cygnus, Latin for “swan,” in the night sky. The Cygnus Loop supernova remnant, also known as the Veil Nebula, is located near one of the swan’s wings, outlined here in a rectangular box. NASA The Cygnus Loop is the remnant of a star that was once 20 times the size of our Sun. Some 20,000 years ago, that star collapsed under its own gravity and erupted into a supernova. Even from 2,600 light-years away, astronomers estimate the flash of light would have been bright enough to see from Earth during the day. This image taken by NASA’s Hubble Space Telescope shows part of the Veil Nebula or Cygnus Loop. To create this colorful image, observations were taken by Hubble’s Wide Field Camera 3 instrument using five different filters. New post-processing methods have further enhanced details of emissions from doubly ionized oxygen (shown here in shades of blue), ionized hydrogen, and ionized nitrogen (shown here in shades of red). ESA/Hubble & NASA, Z. Levay Supernovae are part of a great life cycle. They spray heavy metals forged in a star’s core into the clouds of surrounding dust and gas. They are the source of all chemical elements in our universe heavier than iron, including those that make up our own bodies. From the churned-up clouds and star stuff left in their wake, gases and dust from supernovae gradually clump together to form planets, stars, and new star systems. “Supernovae like the one that created the Cygnus Loop have a huge impact on how galaxies form,” said Brian Fleming, a research professor at the University of Colorado Boulder and principal investigator for the INFUSE mission. The Cygnus Loop provides a rare look at a supernova blast still in progress. Already over 120 light-years across, the massive cloud is still expanding today at approximately 930,000 miles per hour (about 1.5 million kilometers per hour). What our telescopes capture from the Cygnus Loop is not the supernova blast itself. Instead, we see the dust and gas superheated by the shock front, which glows as it cools back down. “INFUSE will observe how the supernova dumps energy into the Milky Way by catching light given off just as the blast wave crashes into pockets of cold gas floating around the galaxy,” Fleming said. To see that shock front at its sizzling edge, Fleming and his team have developed a telescope that measures far-ultraviolet light – a kind of light too energetic for our eyes to see. This light reveals gas at temperatures between 90,000 and 540,000 degrees Fahrenheit (about 50,000 to 300,000 degrees Celsius) that is still sizzling after impact. INFUSE is an integral field spectrograph, the first instrument of its kind to fly to space. The instrument combines the strengths of two ways of studying light: imaging and spectroscopy. Your typical telescopes have cameras that excel at creating images – showing where light is coming from, faithfully revealing its spatial arrangement. But telescopes don’t separate light into different wavelengths or “colors” – instead, all of the different wavelengths overlap one another in the resulting image. Spectroscopy, on the other hand, takes a single beam of light and separates it into its component wavelengths or spectrum, much as a prism separates light into a rainbow. This procedure reveals all kinds of information about what the light source is made of, its temperature, and how it is moving. But spectroscopy can only look at a single sliver of light at a time. It’s like looking at the night sky through a narrow keyhole. The INFUSE instrument captures an image and then “slices” it up, lining up the slices into one giant “keyhole.” The spectrometer can then spread each of the slices into its spectrum. This data can be reassembled into a 3-dimensional image that scientists call a “data cube” – like a stack of images where each layer reveals a specific wavelength of light. PhD student Emily Witt installs the delicate image slicer – the core optical technology for INFUSE – onto its mount in a CU-LASP clean room ahead of integration into the payload. CU Boulder LASP/Brian Fleming Using the data from INFUSE, Fleming and his team will not only identify specific elements and their temperatures, but they’ll also see where those different elements lie along the shock front. “It’s a very exciting project to be a part of,” said lead graduate student Emily Witt, also at CU Boulder, who led most of the assembly and testing of INFUSE and will lead the data analysis. “With these first-of-their-kind measurements, we will better understand how these elements from the supernova mix with the environment around them. It’s a big step toward understanding how material from supernovas becomes part of planets like Earth and even people like us.” To get to space, the INFUSE payload will fly aboard a sounding rocket. These nimble, crewless rockets launch into space for a few minutes of data collection before falling back to the ground. The INFUSE payload will fly aboard a two-stage Black Brant 9 sounding rocket, aiming for a peak altitude of about 150 miles (240 kilometers), where it will make its observations, before parachuting back to the ground to be recovered. The team hopes to upgrade the instrument and launch again. In fact, parts of the INFUSE rocket are themselves repurposed from the DEUCE mission, which launched from Australia in 2022. NASA’s Sounding Rocket Program is conducted at the agency’s Wallops Flight Facility at Wallops Island, Virginia, which is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. NASA’s Heliophysics Division manages the sounding rocket program for the agency. The development of the INFUSE payload was supported by NASA’s Astrophysics Division. View the full article

NASA and Boeing are working to complete the agency’s verification and validation activities ahead of Starliner’s first flight with astronauts to the International Space Station. While Boeing is targeting March to have the spacecraft ready for flight, teams decided during a launch manifest evaluation that a launch in April will better accommodate upcoming crew rotations and cargo resupply missions this spring. The Starliner team works to finalize the mate of the crew module and new service module for NASA’s Boeing Crew Flight Test that will take NASA astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams to and from the International Space Station.Boeing/John Grant Once the spacecraft meets the agency’s safety requirements, NASA’s Boeing Starliner Crew Flight Test (CFT) will see astronauts Butch Wilmore and Suni Williams perform the first crewed mission of the spacecraft designed to take astronauts to and from the orbital laboratory. Ahead of CFT, Boeing has completed P213 tape removal in the upper dome of the Starliner crew compartment and work is underway to remove or remediate the tape in the lower dome of the spacecraft. These hardware remediation efforts inside the Starliner production facility at NASA Kennedy are expected to be completed during the next several weeks. After the P213 tape remediation efforts conclude, engineers will conduct final assessments to ensure acceptable risk of any remaining tape. A set of parachutes is on track to be delivered and installed on the CFT spacecraft by the end of this year to support the current target launch date. Separately, the team also is planning a drop test of Starliner’s updated drogue and main parachutes. The parachutes will incorporate a planned strengthening of main canopy suspension lines and the recent design of the drogue and main parachute soft-link joints, which will increase the safety factor for the system. The drop test is planned for early 2024 based on the current parachute delivery schedule. Boeing and NASA also are planning modifications to the active thermal control system valves to improve long-term functionality following a radiator bypass valve issue discovered during ground operations earlier this year. As discussed during a Starliner media teleconference in June, teams have modified the spacecraft hardware and identified forward work to prevent a similar issue in the future. Options include a system purge to prevent stiction, component upgrades and operational mitigations. Additionally, about 98% of the certification products required for the flight test are complete, and NASA and Boeing anticipate closure on remaining CFT certification products early next year. Meanwhile, NASA and Boeing have made significant progress on requirement closures related to manual crew control of the spacecraft and abort system analysis. The latest version of Starliner’s CFT flight software completed qualification testing and is undergoing standard hardware and software integration testing inside Boeing’s Avionics and Software Integration Lab. Starliner’s crew and service modules remain mated and await continuation of standard preflight processing. The United Launch Alliance Atlas V rocket also is in Florida at Cape Canaveral Space Force Station awaiting integration with the spacecraft. The NASA astronauts who will fly aboard CFT continue to train for their roughly eight-day mission to the orbiting laboratory, which includes working with operations and mission support teams to participate in various simulations across all phases of flight. Starliner completed two uncrewed flight tests, including Orbital Flight Test-2, which docked to the space station on May 21, 2022, following a launch two days prior from Kennedy.

Prominent at the top in this view, are the Columbus laboratory module, the Harmony module and its space-facing docking port, and the Kibo laboratory module with its external pallet. NASA NASA and its industry partners Boeing and SpaceX are planning for the next set of missions to the International Space Station for the agency’s Commercial Crew Program. Crew-8 NASA’s SpaceX Crew-8 mission to the orbiting laboratory is targeted to launch no earlier than mid-February. The mission will carry NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; and mission specialist Jeanette Epps, as well as Roscosmos cosmonaut mission specialist Alexander Grebenkin to the space station to conduct a wide range of operational and research activities. Routine maintenance and processing of the Crew-8 SpaceX Falcon 9 rocket and Dragon spacecraft is in work. This will be the first spaceflight for Dominick, Epps, and Grebenkin, and the third for Barratt. Crew-8 is expected to return to Earth in late August 2024, following a short handover with the agency’s Crew-9 mission. Starliner Crew Flight Test (CFT) The first crewed flight of the Starliner spacecraft, named NASA’s Boeing Crew Flight Test (CFT), is planned for no earlier than mid-April. CFT will send NASA astronauts and test pilots Butch Wilmore and Suni Williams on a demonstration flight to prove the end-to-end capabilities of the Starliner system. Starliner will launch atop a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station in Florida, spend approximately eight days docked to the space station, and return to Earth with a parachute and airbag-assisted ground landing in the desert of the western United States. NASA will provide an updated status of CFT readiness as more information becomes available. Crew-9 Looking further ahead in 2024, NASA and SpaceX are targeting no earlier than mid-August for the launch of the agency’s Crew-9, SpaceX’s ninth crew rotation mission to the space station for NASA. A crew of four will be announced at a later date. 10th Crew Rotation Mission The 10th commercial crew rotation opportunity to the space station is targeted for early 2025. NASA is planning for either SpaceX’s Crew-10 or Boeing’s Starliner-1 mission in this slot. The Starliner-1 date was adjusted to allow for the post-flight review of the Crew Flight Test and incorporation of anticipated learning, approvals of final certification products, and completion of readiness and certification reviews ahead of that mission.

4 min read Glenn Hangar Has Long Been the Face of the Center Painters completing work on NASA Glenn Research Center’s new hangar roof design in July 2016. It was the first time that the roof featured an insignia.Credit: NASA/Bridget Caswell The Flight Research Building, or hangar, at NASA’s Glenn Research Center in Cleveland has not only housed the center’s aircraft and Flight Operations team for decades, but has also served as a visual representation of the center for the public. NASA has taken advantage of the hangar’s size and shape — along with its location near the center’s main entrance, the Cleveland Hopkins International Airport, and multiple freeways — to raise awareness about Glenn to both the local community and Cleveland visitors. In the fall of 1941, the National Advisory Committee for Aeronautics (NACA) completed the first building at its Cleveland laboratory: the hangar. The letters “N-A-C-A” over a pair of wings were installed above its front and back aircraft entrances shortly thereafter. In 1946, “N-A-C-A” was painted in large white block letters onto the black roof facing the airport. This configuration remained in place for twelve years. Pilot Bill Swann climbs into the cockpit of a McDonnell F2H-2B Banshee at the Lewis laboratory in February 1958. Eight months later, the NACA logo on the hangar was removed as the NACA became part of NASA. Swann, who joined the NACA in 1945, spent 35 years flying Lewis aircraft before retiring in 1980.Credit: NASA/Ernie Walker On Oct. 1, 1958, the NACA disbanded, and the laboratory was incorporated into NASA — the nation’s new space agency — as the Lewis Research Center. The next day, the “C” on the hangar roof was painted over with an “S,” and two weeks later, the NACA wings on the front and back were taken down and replaced with small “N-A-S-A” lettering. Transformation of the hangar to reflect the lab’s Oct. 1, 1958, transition from the NACA to NASA and its rechristening as the Lewis Research Center. Credit: NASA During this period, the new agency asked its employees to submit concepts for an official seal. In December 1958, the NASA administrator approved the design of James Modarelli, a graphic illustrator at Lewis and head of the Technical Publications Division. Soon thereafter, he was asked to create a simpler, easier to reproduce version to be used more broadly. In early 1959, Modarelli came up with the large blue insignia that later became known as the “meatball.” In September 1962, a large NASA insignia was installed on the front entrance of the Lewis hangar facing Brookpark Road, where it remained along with the “N-A-S-A” letters on the back and roof for nearly 30 years. In an effort to rebrand the agency in the mid-1970s, NASA replaced Modarelli’s blue insignia with the highly-stylized logo type, also known as “the worm.” Although the change of logos was mandated, the meatball never fully went away, and it remained on the front of the Lewis hangar.

The new sign replaced small “N-A-S-A” letters.Credit: NASA With its fiftieth anniversary approaching in 1991, the center began developing strategies to improve its visibility in the community. The most significant action was a redesign of the hangar graphics. In November 1990, the large red worm logo was installed on the front, and “Lewis Research Center” was added below with lighting to make graphics visible at night.

Two large new meatball signs were constructed in the center’s shops to replace the worm on the front of the hangar and take the place of the 35-year-old insignia on the back. To mark the occasion, the center invited the retired Modarelli to participate in a rededication event at Lewis on Oct. 1, 1997. Modarelli and many of the 250 attendees signed their names on the back of the emblem, which remained above the back entrance until 2022. In 1993, Congress decided to rename the Cleveland facility the Glenn Research Center. By early 1999, the Lewis Research Center text on the front of the hangar was changed to “Glenn Research Center” with “Lewis Field” in smaller type underneath. The hangar roof was painted white in the early 1990s, first with black “N-A-S-A” letters, then with pale blue ones. In 2016, the center chose to repaint the roof with a large NASA meatball insignia, with “Glenn Research Center” in text below. The meatball remains today, a larger-than-life symbol of NASA Glenn’s presence in the community.

2 min read Hubble Captures a Galactic Dance NASA’s Hubble Space Telescope captures the dance of interacting galaxies in Arp-Madore 2339-661 (NGC 7733, NGC 7734). ESA/Hubble and NASA, J. Dalcanton, Dark Energy Survey/DOE/FNAL/NOIRLab/NSF/AURA; Acknowledgement: L. Shatz This striking image from the NASA/ESA Hubble Space Telescope captures the interacting galaxy pair known as Arp-Madore 2339-661. The Arp-Madore catalog is a collection of peculiar galaxies, and this group’s particular peculiarity might be odder than first meets the eye, as there are three galaxies interacting here, not just two. The two clearly defined galaxies are NGC 7733 (smaller, lower right) and NGC 7734 (larger, upper left). The third galaxy is currently referred to as NGC 7733N and is visible if you look carefully at the upper arm of NGC 7733. There you can spot knot-like structure, glowing with a different color than the arm and obscured by dark dust. This could easily pass as part of NGC 7733, but analysis of the velocities (speed and direction) involved reveals that this knot has a considerable additional redshift. This means it is very likely its own entity and not part of NGC 7733. This galaxy group presents one of the many challenges that observational astronomers face: working out whether an astronomical object really is just one, or multiple objects, one lying in front of another as seen from Earth’s perspective! All three galaxies lie quite close to each other, roughly 500 million light-years from Earth in the constellation Tucana, and, as this image shows, they are interacting gravitationally with one another. In fact, some science literature refers to them as a ‘merging group,’ which means they will ultimately become a single entity.

4 min read Aviones de movilidad aérea avanzada: un viaje suave en el futuro Los aviones eléctricos de despegue y aterrizaje vertical, como el que se muestra en este diseño conceptual, podrían ser una parte fundamental de la próxima generación de transporte aéreo. Para crear un mercado realmente viable, los diseñadores tendrán que crear una experiencia cómoda para el pasajero. La misión de movilidad aérea avanzada de la NASA está investigando la calidad del viaje para comprender mejor cómo se deben diseñar estas aeronaves.Gráficos de la NASA/Kyle Jenkins Lee esta historia en inglés aquí. Hoy en día, los pasajeros de avión esperan un viaje tranquilo con pocas turbulencias. Aunque las turbulencias no siempre pueden evitarse, las consideraciones y diseños de los aviones limitan lo que siente el pasajero. Los aviones eléctricos de despegue y aterrizaje vertical (eVTOL por sus siglas en inglés) podrían ser una parte fundamental de la próxima generación de transporte aéreo, pero para crear un mercado viable, los diseñadores tendrán que crear una experiencia cómoda para el pasajero. La misión de Movilidad Aérea Avanzada (AAM por sus siglas en inglés) de la NASA está investigando la calidad de viajes para comprender mejor cómo deben diseñarse estas aeronaves para una experiencia ideal del pasajero. La investigación de la NASA proporciona orientación de diseño a los fabricantes de la industria para garantizar que los pasajeros disfruten de un viaje tranquilo y seguro. “Nosotros creemos que las aeronaves de AAM deberán tener un bajo nivel de ruido en la cabina, una baja vibración de los rotores y ser más resistentes a las turbulencias”, dijo Carlos Malpica, jefe técnico de dinámica y control de vuelo del proyecto de tecnología de elevación vertical revolucionaria (RVLT por sus siglas en inglés) de la NASA. “Tendrán que ser volados de una manera predecible, repetible y no agresiva que no resulte en aceleraciones o rotaciones repentinas de la aeronave”. La misión AAM de la NASA está investigando la respuesta fisiológica humana a los estímulos de movimiento, vibración y ruido que el equipo espera que experimenten los pasajeros en los aviones eVTOL. El año pasado, el proyecto RVLT llevó un estudio en el Simulador de Movimiento Vertical del Centro de Investigación Ames de la NASA en Silicon Valley (California). Voluntarios que se hicieron pasar por pasajeros experimentaron dos vuelos de simulador de corta duración en diferentes niveles de turbulencia. Un viaje fue tranquilo y el otro agitado. El estudio examinó la susceptibilidad al mareo en estas condiciones en aviones eVTOL. La NASA está planeando otros estudios de este tipo para mejor comprender las consecuencias para los pasajeros. La misión AAM incluye varios proyectos centrados en distintas áreas para ayudar a que los aviones eVTOL y otras aeronaves innovadoras vuelen por los cielos. Esto incluye trabajos sobre automatización, ruido, vertipuertos y diseño de vehículos, así como integración del espacio aéreo para mantener la seguridad de todos mientras vuelan. Las agencias gubernamentales, la industria y el público necesitarán combinar sus esfuerzos para construir nuevas autopistas en el cielo. La visión de la NASA consiste en diseñar nuevos sistemas de transporte aéreo seguros, accesibles y económicos junto con socios de la industria, la comunidad, y la Administración Federal de Aviación. Estas nuevas capacidades permitirían a los pasajeros y a la carga viajar a pedido en aviones innovadores y automatizados a través de la ciudad, entre ciudades vecinas o a otros lugares a los que hoy en día se suele acceder en automóvil. La visión de la NASA para la Movilidad Aérea Avanzada, o AAM por sus siglas en inglés, es trazar un nuevo sistema de transporte aéreo seguro, accesible y económico junto con socios de la industria, socios comunitarios y la Administración Federal de Aviación (FAA por sus siglas en inglés). La NASA está investigando cómo podría ser la calidad del viaje para los pasajeros que viajan en aviones eléctricos de despegue y aterrizaje vertical para asegurarse de que es un viaje tranquilo y seguro. En este episodio del Manual de Movilidad Aérea Avanzada de la NASA, analizamos cómo la NASA está especialmente cualificada para esta investigación y por qué es importante para el futuro del vuelo.

The blue areas on this map of Mars are regions where NASA missions have detected subsurface water ice (from the equator to 60 degrees north latitude). Scientists can use the map – part of the Subsurface Water Ice Mapping project – to decide where the first astronauts to set foot on the Red Planet should land.NASA/JPL-Caltech/Planetary Science Institute These Mars global maps show the likely distribution of water ice buried within the upper 3 feet (1 meter) of the planet’s surface and represent the latest data from the SWIM project. Buried ice will be a vital resource for astronauts on Mars, serving as drinking water and a key ingredient for rocket fuel.NASA/JPL-Caltech/PSI The map could help the agency decide where the first astronauts to the Red Planet should land. The more available water, the less missions will need to bring. Buried ice will be a vital resource for the first people to set foot on Mars, serving as drinking water and a key ingredient for rocket fuel. But it would also be a major scientific target: Astronauts or robots could one day drill ice cores much as scientists do on Earth, uncovering the climate history of Mars and exploring potential habitats (past or present) for microbial life. The need to look for subsurface ice arises because liquid water isn’t stable on the Martian surface: The atmosphere is so thin that water immediately vaporizes. There’s plenty of ice at the Martian poles – mostly made of water, although carbon dioxide, or dry ice, can be found as well – but those regions are too cold for astronauts (or robots) to survive for long. That’s where the NASA-funded Subsurface Water Ice Mapping project comes in. SWIM, as it’s known, recently released its fourth set of maps – the most detailed since the project began in 2017. Led by the Planetary Science Institute in Tucson, Arizona, and managed by NASA’s Jet Propulsion Laboratory in Southern California, SWIM pulls together data from several NASA missions, including the Mars Reconnaissance Orbiter (MRO), 2001 Mars Odyssey, and the now-inactive Mars Global Surveyor. Using a mix of data sets, scientists have identified the likeliest places to find Martian ice that could be accessed from the surface by future missions. The ice-exposing impact crater at the center of this image is an example of what scientists look for when mapping places where future astronauts should land on Mars. It’s one of several such impacts incorporated into the latest version of a series of NASA-funded maps of subsurface water ice on the Red Planet.NASA/JPL-Caltech/University of Arizona Instruments on these spacecraft have detected what look like masses of subsurface frozen water along Mars’ mid-latitudes. The northern mid-latitudes are especially attractive because they have a thicker atmosphere than most other regions on the planet, making it easier to slow a descending spacecraft. The ideal astronaut landing sites would be a sweet spot at the southernmost edge of this region – far enough north for ice to be present but close enough to the equator to ensure the warmest possible temperatures for astronauts in an icy region. “If you send humans to Mars, you want to get them as close to the equator as you can,” said Sydney Do, JPL’s SWIM project manager. “The less energy you have to expend on keeping astronauts and their supporting equipment warm, the more you have for other things they’ll need.” Building a Better Map Previous iterations of the map relied on lower-resolution imagers, radar, thermal mappers, and spectrometers, all of which can hint at buried ice but can’t outright confirm its presence or quantity. For this latest SWIM map, scientists relied on two higher-resolution cameras aboard MRO. Context Camera data was used to further refine the northern hemisphere maps and, for the first time, HiRISE (High-Resolution Imaging Science Experiment) data was incorporated to provide the most detailed perspective of the ice’s boundary line as close to the equator as possible. Scientists routinely use HiRISE to study fresh impact craters caused by meteoroids that may have excavated chunks of ice. Most of these craters are no more than 33 feet (10 meters) in diameter, although in 2022 HiRISE captured a 492-foot-wide (150-meter-wide) impact crater that revealed a motherlode of ice that had been hiding beneath the surface. In this artist’s concept, NASA astronauts drill into the Martian subsurface. The agency has created new maps that show where ice is most likely to be easily accessible to future astronauts.NASA “These ice-revealing impacts provide a valuable form of ground truth in that they show us locations where the presence of ground ice is unequivocal,” said Gareth Morgan, SWIM’s co-lead at the Planetary Science Institute. “We can then use these locations to test that our mapping methods are sound.” In addition to ice-exposing impacts, the new map includes sightings by HiRISE of so-called “polygon terrain,” where the seasonal expansion and contraction of subsurface ice causes the ground to form polygonal cracks. Seeing these polygons extending around fresh, ice-filled impact craters is yet another indication that there’s more ice hidden beneath the surface at these locations. There are other mysteries that scientists can use the map to study, as well. “The amount of water ice found in locations across the Martian mid-latitudes isn’t uniform; some regions seem to have more than others, and no one really knows why,” said Nathaniel Putzig, SWIM’s other co-lead at the Planetary Science Institute. “The newest SWIM map could lead to new hypotheses for why these variations happen.” He added that it could also help scientists tweak models of how the ancient Martian climate evolved over time, leaving larger amounts of ice deposited in some regions and lesser amounts in others. SWIM’s scientists hope the project will serve as a foundation for a proposed Mars Ice Mapper mission – an orbiter that would be equipped with a powerful radar custom-designed to search for near-surface ice beyond where HiRISE has confirmed its presence.

5 min read NASA, Pacific Disaster Center Increase Landslide Hazard Awareness Communities worldwide now have access to a powerful tool to increase their awareness of landslide hazards, thanks to NASA and the Pacific Disaster Center. A humanitarian worker from USAID observes the impacts of a landslide. USAID deployed an elite Disaster Assistance Response Team on Nov. 17, 2020, to lead the U.S. response to Hurricanes Eta and Iota.USAID’s Bureau for Humanitarian Assistance After years of development and testing, NASA’s Landslide Hazard Assessment for Situational Awareness model (LHASA) has been integrated into the Pacific Disaster Center’s (PDC) multi-hazard monitoring, alerting, and decision-support platform, DisasterAWARE. LHASA allows researchers to map rainfall-triggered landslide hazards, giving DisasterAWARE users around the world a robust tool for identifying, tracking, and responding to these threats. The aim is to equip communities with timely and critical risk awareness that bolsters disaster resilience and safeguards lives and livelihoods. Landslides cause thousands of deaths and billions of dollars in damage every year. Developing countries often bear disproportionate losses due to lack of access to hazard early warning systems and other resources for effective risk reduction and recovery. Reports from the United Nations Office for Disaster Risk Reduction emphasize that early warning systems and early action are among the most effective ways to decrease disaster-related deaths and losses. The distribution of reported fatalities from 10,804 rainfall-triggered landslides in NASA’s Global Landslide Catalog (GLC) from 2007 to 2017. White dots represent incidents with zero reported fatalities and dots in the color scale from pink to red represent incidents in the range of 1-5000 fatalities. The NASA landslides team, based primarily out of NASA’s Goddard Space Flight Center, develops the Global Landslide Catalog and LHASA with support from NASA’s Disasters program. NASA Scientific Visualization Studio “Some local authorities develop their own systems to monitor landslide risk, but there isn’t a global model that works in the same way. That’s what defines LHASA: it works all the time and it covers most regions of the world,” says Robert Emberson, NASA Disasters associate program manager and a key member of the NASA landslides team. “Thanks to our collaboration with the Pacific Disaster Center, this powerful landslide technology is now even more accessible for the communities that need it most.” LHASA uses a machine learning model that combines data on ground slope, soil moisture, snow, geological conditions, distance to faults, and the latest near real-time precipitation data from NASA’s IMERG product (part of the Global Precipitation Measurement mission). The model has been trained on a database of historical landslides and the conditions surrounding them, allowing it to recognize patterns that indicate a landslide is likely. The result is a landslide “nowcast” – a map showing the potential of rainfall-triggered landslides occurring for any given region within the past day. This map of hazard likelihood can help agencies and officials rapidly assess areas where the current landslide risk is high. It can also give disaster response teams critical information on where a landslide may have occurred so they can investigate and deploy life-saving resources. In 2021, a 7.2 magnitude earthquake struck Haiti, triggering a series of landslides across the country. Landslides can destroy infrastructure and impede the movement of people and life-saving aid. United Nations World Food Programme Partnering to Protect the Vulnerable Generating landslide nowcasts is merely the first step. To be truly effective, vulnerable communities must receive the data in a way that is accessible and easy to integrate into existing disaster management plans. That’s where the Pacific Disaster Center comes in. PDC is an applied research center managed by the University of Hawaii, and it shares NASA’s goal to reduce global disaster risk through innovative uses of science and technology. Its flagship DisasterAWARE software provides early warnings and risk assessment tools for 18 types of natural hazards and supports decision-making by a wide range of disaster management agencies, local governments, and humanitarian organizations. Prominent users include the International Federation of Red Cross and Red Crescent Societies (IFRC), the United Nations Office for the Coordination of Humanitarian Affairs (UN OCHA), and the World Food Programme (WFP). “The close pairing of our organizations and use of PDC’s DisasterAWARE platform for early warning has been a special recipe for success in getting life-saving information into the hands of decision-makers and communities around the world,” said Chris Chiesa, PDC deputy executive director. The collaboration with PDC brings NASA’s landslide tool to tens of thousands of existing DisasterAWARE users, dramatically increasing LHASA’s reach and effectiveness. Chiesa notes that teams in El Salvador, Honduras, and the Dominican Republic have already begun using these new capabilities to assess landslide hazards during the 2023 rainy season. This screenshot from PDC’s DisasterAWARE Pro software shows LHASA landslide hazard probabilities for Myanmar in Sept. 2023. Red areas indicate the highest risk for landslide occurrence within the past three hours, while orange and yellow indicate lesser risk. Pacific Disaster Center PDC’s software ingests and interprets LHASA model data and generates maps of landslide risk severity. It then uses the data to generate landslide hazard alerts for a chosen region that the DisasterAWARE mobile app pushes to users. These alerts give communities critical information on potential hazards, enabling them to take protective measures. DisasterAWARE also creates comprehensive regional risk reports that estimate the number of people and infrastructure exposed to a disaster – focusing specifically on things like bridges, roads, and hospitals that could complicate relief efforts when damaged. This information is critical for allowing decision-makers to effectively deploy resources to the areas that need them most. DisasterAWARE landside risk report for Myanmar, showing estimated population, infrastructure and capital exposure to landslide risk, as well as the community’s needs. Pacific Disaster Center This effort between NASA and the PDC builds upon a history of fruitful cooperation between the organizations. In 2022, they deployed a NASA global flood modeling tool to enhance DisasterAWARE’s flood early-warning capabilities. They have also shared data and expertise during multiple disasters, including Hurricane Iota in 2020, the 2021 earthquake in Haiti, and the devastating August 2023 wildfires in Maui, PDC’s base of operations. “The LHASA model is all open-source and leverages publicly available data from NASA and partners,” says Dalia Kirschbaum, lead of the NASA landslides team and director of Earth Sciences at NASA’s Goddard Space Flight Center. “This enables other researchers and disaster response communities to adapt the framework to regional or local applications and further awareness at scales relevant to their decision-making needs.” Kirschbaum and her team were recently awarded the prestigious NASA Software of the Year award for their work developing LHASA.

4 min read NASA Tech Breathes Life Into Potentially Game-Changing Antenna Design Some 30 years ago, a young engineer named Christopher Walker was home in the evening making chocolate pudding when he got what turned out to be a very serendipitous call from his mother. Taking the call, he shut off the stove and stretched plastic wrap over the pot to keep the pudding fresh. By the time he returned, the cooling air in the pot had drawn the wrap into a concave shape, and in that warped plastic, he saw something – the magnified reflection of an overhead lightbulb – that gave him an idea that could revolutionize space-based sensing and communications. That idea became the Large Balloon Reflector (LBR), an inflatable device that creates wide collection apertures that weigh a fraction of today’s deployable antennas. Now, with an assist from NASA’s Innovative Advanced Concepts (NIAC) program, funded by the agency’s Space Technology Mission Directorate, which supports visionary innovations from diverse sources, Walker’s decades-old vision is coming to fruition. The concept turns part of the inside surface of an inflated sphere into a parabolic antenna. A section comprising about a third of the balloon’s interior surface is aluminized, giving it reflective properties. With NIAC funding, and a grant from the U.S. Naval Research Laboratory, Walker was able to develop and demonstrate technologies for a 33-foot-diameter (10 meters) LBR that was carried to the stratosphere by a giant balloon. For comparison, the aperture of NASA’s massive James Webb Space Telescope is over 21 feet (6.5 meters) in diameter. “There was no place other than NIAC within NASA to get this off the ground,” says Walker, now a astronomy and optical engineering professor at the University of Arizona in Tucson. “At first, I was afraid to share the idea with colleagues because it sounded so crazy. You need a program within NASA that will actually look at the radical ideas, and NIAC is it.” Parabolic dish antennas use their concave shape to capture and concentrate electromagnetic radiation. The larger the antenna’s diameter, or aperture, the more effective it is for capturing light or radio waves and transmitting radio signals over great distances. In astronomy, there is a tremendous advantage to placing telescopes above the Earth’s atmosphere, which tends to distort or degrade signals coming from space. The challenge is that traditional large reflector antennas are heavy, unwieldy, and difficult to stow, leading to launch constraints and risky in-space deployment schemes. The LBR design solves both problems. Made of a thin film structure, it inflates like a beachball, providing a stable parabolic-dish shape without the need for bulky and complex deployable hardware, and can fold into a tiny volume. In 2018, Freefall Aerospace, a company co-founded by Walker to develop and market the technology, demonstrated the LBR’s potential aboard NASA’s stadium-sized stratospheric balloon, which carried a 3.28-foot scale model to an altitude of 159,000 feet. Next up for the technology is a high-speed communications demonstration in low Earth orbit aboard a 6-unit CubeSat, about the size of a shoebox, called CatSat. It was selected for flight in 2019 as part of NASA’s CubeSat Launch Initiative. It is a joint effort involving NASA, Freefall Aerospace, the University of Arizona, and Rincon Research Corporation in Tucson, Arizona. After reaching low-Earth orbit, CatSat’s inflatable antenna deployment system will deploy from its container, inflate to a diameter of about one-and-a-half feet, and begin transmitting back high-definition Earth photos. The mission is slated for launch with several other CubeSats on Firefly Aerospace’s Alpha rocket as part of the Educational Launch of Nanosatellites (ELaNa) 43 mission. A more ambitious lunar mission concept is also being explored. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, would use the inflatable antenna in tandem with a new instrument called Terahertz Spectrometer for In-Situ Resource Utilization, a miniature, high-power laser precisely calibrated to detect water, a critical exploration resource. “The technology demonstrated by CatSat opens the door to the possibility of future lunar, planetary and deep-space missions using CubeSats,” said Walker. It might be difficult to believe this all started because a young engineer’s idea of dinner one evening was what most would consider dessert. Then again, one could say the proof was in the pudding.

The red, green, and blue elements reflect low, medium, and high energy X-rays, respectively, as detected by Chandra. The IXPE data, which measure the polarization of the X-ray light, is show in purple in the upper left corner, with the addition of lines representing the outward movement of the remnant’s magnetic field. X-ray: NASA/CXC/SAO (Chandra); NASA/MSFC/Nanjing Univ./P. Zhou et al. (IXPE); IR: NASA/JPL/CalTech/Spitzer; Image Processing: NASA/CXC/SAO/J.Schmidt NASA’s IXPE (Imaging X-ray Polarimetry Explorer) telescope has captured the first polarized X-ray imagery of the supernova remnant SN 1006. The new results expand scientists’ understanding of the relationship between magnetic fields and the flow of high-energy particles from exploding stars. “Magnetic fields are extremely difficult to measure, but IXPE provides an efficient way for us to probe them,” said Dr. Ping Zhou, an astrophysicist at Nanjing University in Jiangsu, China, and lead author of a new paper on the findings, published in The Astrophysical Journal. “Now we can see that SN 1006’s magnetic fields are turbulent, but also present an organized direction.” Situated some 6,500 light-years from Earth in the Lupus constellation, SN 1006 is all that remains after a titanic explosion, which occurred either when two white dwarfs merged or when a white dwarf pulled too much mass from a companion star. Initially spotted in spring of 1006 CE by observers across China, Japan, Europe, and the Arab world, its light was visible to the naked eye for at least three years. Modern astronomers still consider it the brightest stellar event in recorded history. Since modern observation began, researchers have identified the remnant’s strange double structure, markedly different from other, rounded supernova remnants. It also has bright “limbs” or edges identifiable in the X-ray and gamma-ray bands. “Close-proximity, X-ray-bright supernova remnants such as SN 1006 are ideally suited to IXPE measurements, given IXPE’s combination of X-ray polarization sensitivity with the capability to resolve the emission regions spatially,” said Douglas Swartz, a Universities Space Research Association researcher at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “This integrated capability is essential to localizing cosmic-ray acceleration sites.” Previous X-ray observations of SN 1006 offered the first evidence that supernova remnants can radically accelerate electrons, and helped identify rapidly expanding nebulae around exploded stars as a birthplace for highly energetic cosmic rays, which can travel at nearly the speed of the light. Scientists surmised that SN 1006’s unique structure is tied to the orientation of its magnetic field, and theorized that supernova blast waves in the northeast and southwest move in the direction aligned with the magnetic field, and more efficiently accelerate high-energy particles. IXPE’s new findings helped validate and clarify those theories, said Dr. Yi-Jung Yang, a high-energy astrophysicist at the University of Hong Kong and coauthor of the paper. “The polarization properties obtained from our spectral-polarimetric analysis align remarkably well with outcomes from other methods and X-ray observatories, underscoring IXPE’s reliability and strong capabilities, Yang said. For the first time, we can map the magnetic field structures of supernova remnants at higher energies with enhanced detail and accuracy – enabling us to better understand the processes driving the acceleration of these particles. Dr. Yi-Jung Yang High-energy astrophysicist at the University of Hong Kong Researchers say the results demonstrate a connection between the magnetic fields and the remnant’s high-energy particle outflow. The magnetic fields in SN 1006’s shell are somewhat disorganized, per IXPE’s findings, yet still have a preferred orientation. As the shock wave from the original explosion passes through the surrounding gas, the magnetic fields become aligned with the shock wave’s motion. Charged particles are trapped by the magnetic fields around the original point of the blast, where they quickly receive bursts of acceleration. Those speeding high-energy particles, in turn, transfer energy to keep the magnetic fields strong and turbulent. IXPE has observed three supernova remnants – Cassiopeia A, Tycho, and now SN 1006 – since launching in December 2021, helping scientists develop a more comprehensive understanding of the origin and processes of the magnetic fields surrounding these phenomena. Scientists were surprised to find that SN 1006 is more polarized than the other two supernova remnants, but that all three show magnetic fields oriented such that they point outward from the center of the explosion. As researchers continue to explore IXPE data, they are re-orienting their understanding of how particles get accelerated in extreme objects like these. IXPE is a collaboration between NASA and the Italian Space Agency with partners and science collaborators in 12 countries. IXPE is led by NASA’s Marshall Space Flight Center in Huntsville, Alabama. Ball Aerospace, headquartered in Broomfield, Colorado, manages spacecraft operations together with the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder.

The Oct. 19 event was in Building 4203 at NASA’s Marshall Space Flight Center. Mission Success is in Our Hands is a safety initiative collaboration between Marshall and Jacobs. Garrett Harencak, Jacobs vice president and president of Mission Support and Test Services LLC, makes a point during his presentation at the Mission Success is in Our Hands hybrid Shared Experiences Forum on Oct. 19. NASA/Danielle Burleson Harencak also shared his experiences in working and leading nuclear safety, high hazard projects, and conducting operations in the nuclear and national security industries. Using the analogy of a lion chasing chipmunks or zebras, he said leaders must focus on the most important tasks in a mission as opposed to spending time on lesser objectives. Harencak said that while a lion is quick and nimble enough to chase chipmunks, the rodent does not provide as much nutritional value to a lion’s pride when compared to a zebra. “Are you chasing chipmunks or zebras?” Harencak asked during his presentation. “You have to focus on what matters most. And when you tell your team members to chase chipmunks, they know it’s not the most important thing they should be doing that day.” He also stressed the importance of practicing a routine to be prepared for an unplanned event to happen. “The value of practice and repetition is that it allows you to overcome when things go wrong, and things will go wrong,” Harencak said. “Practice reduces fear. Without practice, what follows fear is panic, and what follows panic are bad decisions.” Golden Eagle Award winner Jennifer Robinson, center, receives a plaque commemorating her award during the Oct. 19 Mission Success is in Our Hands event. Joining Robinson are Bill Hill, left, director of the Safety and Mission Assurance Directorate at Marshall, and Jeff Haars, Jacobs vice president and program manager for Jacobs Space Exploration Group.NASA/Danielle Burleson In talking about leadership, Harencak said it’s everyone’s responsibility to “be the boss you always wanted to work for” in building a culture of mission success, particularly in a high-hazard business. “It’s a constant struggle as leaders to build an atmosphere that allows everyone to do what’s necessary to make sure we do it safely and securely,” Harencak said. Jennifer Robinson was awarded the Golden Eagle Award during the event. Robinson, a Jacobs Space Exploration Group employee, is the SLS (Space Launch System) debris analysis team lead. The team is responsible for analyzing the launch debris environment and identifying the debris risk to SLS. Bill Hill, director of the Safety and Mission Assurance Directorate at Marshall, said Robinson’s team developed a process for evaluating potential debris issues during countdown in the months leading up to the Artemis I launch. Eight new testimonial banners are displayed as part of the Mission Success is in Our Hands Shared Experiences ForumNASA/Danielle Burleson “This process subsequently was adopted as the standing operating procedure that allows for imagery and debris teams to work together to disposition debris findings during critical hours leading to launch,” Hill said. Since 2015, the Golden Eagle Award has been presented by Mission Success is in Our Hands. 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. As part of the final Shared Experiences Forum of the year, the Mission Success committee displayed eight new testimonial banners featuring Marshall team members as part of its rebranding. The banners will be placed across the center.

The CFC Kickoff Charities Fair was held in Marshall’s Activities Building 4316. Ten charities from the Tennessee Valley participated in the event to talk about their needs and how Marshall team members could help or get involved through volunteering. This year’s theme is “Give Happy.” Marshall Associate Director, Technical, Larry Leopard, welcomes team members to the CFC Kickoff Charities Fair. NASA/Alex Russell Every year, federal workers come together to raise money and volunteer for their favorite charities. The CFC, in its 62nd year, is the world’s largest and most successful annual workplace charity campaign for federal employees and retirees. Since its inception, the campaign has raised nearly $8.7 billion for charities and people in need. During the 2022 campaign year, Marshall team members pledged $295,454. The 2023 CFC solicitation period started Oct. 2 and runs through Jan. 15, 2024. Marshall’s goal this year is to increase participation by 15%. Last year, 343 people at Marshall contributed. Donors can contribute financially via credit or debit card payment or PayPal, with some team members able to donate a portion of their paycheck during the campaign period. Donors can also contribute their time at a participating charity, with each volunteer hour counted toward the overall fundraising goal. Team members can visit Inside Marshall for more information about this year’s campaign. Marshall team members visit some of the different charities represented at the CFC kickoff event. NASA/Alex Russell In the Greater Tennessee Valley Zone, there are 69 charities currently listed as active CFC participants, from community health clinics and animal rescues to veteran and social justice groups. “We can create change by supporting our favorite causes and promoting a greater good,” Marshall Associate Director, Technical, Larry Leopard said at the event kickoff. “For this year’s campaign, I want to challenge everyone at Marshall to donate or volunteer at a local charity. Take the time to discover a cause that you and your family can connect with. Make a small donation, or volunteer as a family or with friends. These actions matter so much to our local nonprofits and our community.” Learn more about CFC and see the list of participating charities in your community by visiting https://cfcgiving.opm.gov. › Back to Top Take 5 with Keith Savoy By Matt Higgins Keith Savoy credits his father for teaching him how to do a number of things. His father also inspired him to pursue a career in engineering. “My dad, a U.S. Marine, sugar cane farmer, and shipping and loading supervisor for CF Industries, inspired me to do lots of things,” said Savoy, chief operating officer at NASA’s Michoud Assembly Facility. “Although he did not have a college degree, he was a jack of all trades and could rebuild vehicle engines, weld, perform carpentry, and do many other tasks that are essential to our daily lives.” Keith Savoy is the chief operating officer at NASA’s Michoud Assembly Facility.NASA/Michael DeMocker In his role, Savoy oversees the day-to-day administrative and operational functions at Michoud, helping sustain NASA’s SLS (Space Launch System) and Orion spacecraft production efforts, and coordinating requirements and logistics with the facility’s tenant leadership for approximately 3,500 employees. Michoud is managed by NASA’s Marshall Space Flight Center. In addition to learning from his father, Savoy credits an internship with Lockheed Martin for spurring his interest in working with NASA. “During my junior year in college, I was selected to an intern program with Lockheed Martin, working for Mr. George Hasting during the summer,” Savoy said. “As a mentor, he provided insight and leadership, as well as piquing my interest in the space program. This is what led me to ultimately accepting a position with Lockheed Martin at Michoud after I graduated.” Question: What excites you most about the future of human space exploration and your team’s role it? Savoy: What excites me most about the future of human space exploration is the continued involvement of the Michoud Assembly Facility in the manufacturing of several components for Artemis, including the SLS core stage, future SLS Exploration Upper Stage, and the Orion pressure vessel. Michoud has been involved in the manufacturing and assembly of space flight hardware since the 1960s. I have been fortunate to be involved in the External Tank Program for shuttle and Artemis. I am very proud of the Michoud team’s accomplishment of successfully executing all facility and program modifications to support these two major NASA programs. Question: What has been the proudest moment of your career and why? Savoy: I believe the proudest moments of my career have been every time I have watched a shuttle launch and most recently the Artemis I launch, knowing Michoud and everyone working there contributed to the successful launch. I usually get nervous right before the powerful RS-25 engines ignite and the vehicle slowly pulls away from the launch pad. Question: Who or what drives/motivates you? Savoy: I have always been a self-motivated individual, whether it was sports, education, or my career. I am very passionate about a lot of things, as most people who work around me know. Question: What advice do you have for employees early in their NASA career or those in new leadership roles? Savoy: Take every opportunity to cross train in multiple jobs if available. I started my career as an engineer in the Operations and Maintenance organization with Lockheed Martin during the External Tank Program. I held numerous jobs with Lockheed with increasing areas of responsibility to include new business planner, environmental engineer, electrical engineering supervisor, critical systems associate manager, Enhancement Team manager and Operational Planning and Layout manager. After my 20 years with Lockheed Martin, I transitioned to NASA as a logistics engineer for the site and later to the facilities operations manager. Finally, in 2023 I accepted the responsibility of NASA chief operating officer. Each one of these learning opportunities/challenges has provided me with necessary technical and leadership attributes to effectively manage a complex site like Michoud with multiple program and site tenants. Question: What do you enjoy doing with your time while away from work? Savoy: I enjoy working out/exercising, relaxing at my camp in Pierre Part, Louisiana, watching or going to LSU Tigers and New Orleans Saints football games, and traveling with my family. We typically have a family vacation once a year; the next one is Yellowstone National Park. Higgins, a Manufacturing Technical Solutions Inc. employee, works in communications at Michoud Assembly Facility. › Back to Top NASA’s Innovative Rocket Nozzle Paves Way for Deep Space Missions By Ray Osorio NASA recently built and tested an additively-manufactured – or 3D printed – rocket engine nozzle made of aluminum, making it lighter than conventional nozzles and setting the course for deep space flights that can carry more payloads. Under the agency’s Announcement of Collaborative Opportunity, engineers from NASA’s Marshall Space Flight Center partnered with Elementum 3D, in Erie, Colorado, to create a weldable type of aluminum that is heat resistant enough for use on rocket engines. Compared to other metals, aluminum is lower density and allows for high-strength, lightweight components. The RAMFIRE nozzle performs a hot fire test at Marshall’s East test area stand 115. The nozzle, made of the novel aluminum alloy 6061-RAM2, experiences huge temperature gradients. As hot gasses approach 6000 degrees Fahrenheit and undergo combustion, icicles are forming on the outside of the engine nozzle.NASA However, due to its low tolerance to extreme heat and its tendency to crack during welding, aluminum is not typically used for additive manufacturing of rocket engine parts – until now. Meet NASA’s latest development under the Reactive Additive Manufacturing for the Fourth Industrial Revolution, or RAMFIRE, project. Funded under NASA’s STMD (Space Technology Mission Directorate), RAMFIRE focuses on advancing lightweight, additively manufactured aluminum rocket nozzles. The nozzles are designed with small internal channels that keep the nozzle cool enough to prevent melting. With conventional manufacturing methods, a nozzle may require as many as thousand individually joined parts. The RAMFIRE nozzle is built as a single piece, requiring far fewer bonds and significantly reduced manufacturing time. At the RPM Innovation facility in Rapid City, South Dakota, manufacturing for a large-scale aerospike demonstration nozzle with integral channels is underway. The laser powder directed energy deposition process creates a melt pool using a laser and blows powder into the melt pool to deposit material layer by layer. NASA engineers will use the nozzle as a proof of concept to inform future component designs.RPM Innovation NASA and Elementum 3D first developed the novel aluminum variant known as A6061-RAM2 to build the nozzle and modify the powder used with LP-DED (laser powder directed energy deposition) technology. Another commercial partner, RPM Innovations in Rapid City, South Dakota, used the newly invented aluminum and specialized powder to build the RAMFIRE nozzles using their LP-DED process. “Industry partnerships with specialty manufacturing vendors aid in advancing the supply base and help make additive manufacturing more accessible for NASA missions and the broader commercial and aerospace industry,” said Paul Gradl, RAMFIRE principal investigator at Marshall. NASA’s Moon to Mars objectives require the capability to send more cargo to deep space destinations. The novel alloy could play an instrumental role in this by enabling the manufacturing of lightweight rocket components capable of withstanding high structural loads. Seen here at NASA’s Marshall Space Flight Center, and developed with the same 6061-RAM2 aluminum material used under the RAMFIRE project, is a vacuum jacket manufacturing demonstrator tank. The component, made for cryogenic fluid application, is designed with a series of integral cooling channels that have a wall thickness of about 0.06 inches.NASA “Mass is critical for NASA’s future deep space missions,” said John Vickers, principal technologist for STMD advanced manufacturing. “Projects like this mature additive manufacturing along with advanced materials, and will help evolve new propulsion systems, in-space manufacturing, and infrastructure needed for NASA’s ambitious missions to the Moon, Mars, and beyond.” Earlier this summer at Marshall’s East Test Area, two RAMFIRE nozzles completed multiple hot-fire tests using liquid oxygen and liquid hydrogen, as well as liquid oxygen and liquid methane fuel configurations. With pressure chambers in excess of 825 pounds per square inch – more than anticipated testing pressures – the nozzles successfully accumulated 22 starts and 579 seconds, or nearly 10 minutes, of run time. This event demonstrates the nozzles can operate in the most demanding deep-space environments. “This test series marks a significant milestone for the nozzle,” Gradl said. “After putting the nozzle through the paces of a demanding hot-fire test series, we’ve demonstrated the nozzle can survive the thermal, structural, and pressure loads for a lunar lander scale engine.” NASA engineers Tessa Fedotowsky and Ben Williams, from Marshall, inspect the RAMFIRE nozzle following successful hot-fire testing.NASA In addition to successfully building and testing the rocket engine nozzles, the RAMFIRE project has used the RAMFIRE aluminum material and additive manufacturing process to construct other advanced large components for demonstration purposes. These include a 36-inch diameter aerospike nozzle with complex integral coolant channels and a vacuum-jacketed tank for cryogenic fluid applications. NASA and industry partners are working to share the data and process with commercial stakeholders and academia. Various aerospace companies are evaluating the novel alloy and the LP-DED additive manufacturing process and looking for ways it can be used to make components for satellites and other applications.

And the good news is, there’s still more of NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer) sample to collect. The curation team processing NASA’s asteroid Bennu sample from the OSIRIS-REx mission has surpassed the agency’s goal of bringing at least 60 grams to Earth, removing and collecting 2.48 ounces (70.3 grams) of rocks and dust from the sampler hardware.NASA The sample processed so far includes the rocks and dust found on the outside of the sampler head, as well as a portion of the bulk sample from inside the head, which was accessed through the head’s mylar flap. Additional material remaining inside the sampler head, called the Touch-and-Go Sample Acquisition Mechanism, or TAGSAM, is set for removal later, adding to the mass total. In the last week, the team at NASA’s Johnson Space Center changed its approach to opening the TAGSAM head, which contained the bulk of the rocks and dust collected by the spacecraft in 2020. After multiple attempts at removal, the team discovered two of the 35 fasteners on the TAGSAM head could not be removed with the current tools approved for use in the OSIRIS-REx glovebox. The team has been working to develop and implement new approaches to extract the material inside the head, while continuing to keep the sample safe and pristine. As a first step, the team successfully accessed some of the material by holding down the head’s mylar flap and removing the sample inside with tweezers or a scoop, depending on material size. The collection and containment of material through this method, combined with the earlier collection of material located outside the head, yielded a total mass exceeding the 60 grams required. The team will spend the next few weeks developing and practicing a new procedure to remove the remaining asteroid sample from the TAGSAM sampler head while simultaneously processing the material that was collected last week. The OSIRIS-REx science team will also proceed with its plan to characterize the extracted material and begin analysis of the bulk sample obtained so far. All curation work on the sample – and the TAGSAM head – is performed in a specialized glovebox under a flow of nitrogen to keep it from being exposed to Earth’s atmosphere, preserving the sample’s pristine state for subsequent scientific analysis. The tools for any proposed solution to extract the remaining material from the head must be able to fit inside the glovebox and not compromise the scientific integrity of the collection, and any procedures must be consistent with the clean room’s standards. While the procedure to access the final portion of the material is being developed, the team has removed the TAGSAM head from the active flow of nitrogen in the glovebox and stored it in its transfer container, sealed with an O-ring and surrounded by a sealed Teflon bag to make sure the sample is kept safe in a stable, nitrogen-rich, environment. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center for the agency’s Science Mission Directorate in Washington.

On Sept. 7, 2023, during its 54th close flyby of Jupiter, NASA’s Juno mission captured this view of an area in the giant planet’s far northern regions called Jet N7. The image shows turbulent clouds and storms along Jupiter’s terminator, the dividing line between the day and night sides of the planet. The low angle of sunlight highlights the complex topography of features in this region, which scientists have studied to better understand the processes playing out in Jupiter’s atmosphere. As often occurs in views from Juno, Jupiter’s clouds in this picture lend themselves to pareidolia, the effect that causes observers to perceive faces or other patterns in largely random patterns. Citizen scientist Vladimir Tarasov made this image using raw data from the JunoCam instrument. At the time the raw image was taken, the Juno spacecraft was about 4,800 miles (about 7,700 kilometers) above Jupiter’s cloud tops, at a latitude of about 69 degrees north. JunoCam’s raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing.

4 min read AWE Launching to Space Station to Study Atmospheric Waves via Airglow NASA’s Atmospheric Waves Experiment, or AWE, mission is scheduled to launch to the International Space Station in November 2023, where it will make use of a natural, ethereal glow in Earth’s sky to study waves in our planet’s atmosphere. Built by Utah State University’s Space Dynamics Laboratory in North Logan, Utah, AWE will be mounted on the exterior of the space station. From this perch, AWE will stare down toward Earth, tracking undulations in the air known as atmospheric gravity waves (AGWs). Primarily originating in the lowest level of the atmosphere, AGWs may be caused by strong weather events such as tornadoes, hurricanes, or even thunderstorms. These weather events can momentarily push pockets of high-density air upwards into the atmosphere before the air sinks back down. This up-and-down bobbing often leaves behind distinctive ripples patterns in the clouds. This photo shows examples of cloud patterns caused by atmospheric gravity waves (AGWs). Warmer, denser air from lower in the atmosphere holds more water, so as weather events like wind and storms push those pockets of air to higher altitudes, that water forms clouds at the crests of those waves. Courtesy Alexa Halford; used with permission But AGWs continue all the way to space, where they contribute to what’s known as space weather – the tumultuous exchange of energy in the area surrounding our planet that can disrupt satellite and communications signals. AWE will measure AGWs at an atmospheric layer that begins some 54 miles (87 kilometers) in altitude, known as the mesopause. “This is the first time that AGWs, especially the small-scale ones, will be measured globally at the mesopause, the gateway to the space,” said Michael Taylor, professor of physics at Utah State University and principal investigator for the mission. “More importantly, this is the first time we will be able to quantify the impacts of AGWs on space weather.” This image taken from the International Space Station shows swaths of airglow hovering in Earth’s atmosphere. NASA’s new Atmospheric Waves Experiment will observe airglow from a perch on the space station to help scientists understand, and ultimately improve forecasts of, space weather changes in the upper atmosphere. NASA At the mesopause, where AWE will make its measurements, AGWs are revealed by colorful bands of light in our atmosphere known as airglow. AWE will “see” these waves by recording variations of airglow in infrared light, a wavelength range too long for human eyes to see. At these altitudes our atmosphere dips to its coldest temperatures – reaching as low as -150 degrees Fahrenheit (-101 degrees Celsius) – and the faint glow of infrared light is at its brightest. By watching that infrared airglow grow brighter and dimmer as waves move through it, AWE will enable scientists to compute the size, power, and dispersion of AGWs like never before. It was also designed to see smaller AGWs, detecting short-scale ripples in airglow that previous missions would miss. “AWE will be able to resolve waves at finer horizontal scales than what satellites can usually see at those altitudes, which is part of what makes the mission unique,” said Ruth Lieberman, AWE mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. This artist’s conception depicts AWE scanning the atmosphere from aboard the International Space Station. AWE will measure variations in infrared airglow to track atmospheric gravity waves as they move up from the lower atmosphere into space. Utah State University Space Dynamics Laboratory From its vantage point on the space station, AWE’s Advanced Mesospheric Temperature Mapper (AMTM) instrument will scan the mesopause below it. AWE’s AMTM consists of four identical telescopes, which together comprise a wide-field-of-view imaging radiometer, an instrument that measures the brightness of light at specific wavelength ranges. The relative brightness of different wavelengths can be used to create temperature maps, which in turn reveal how AGWs are moving through the atmosphere. It will be the most thorough study of AGWs and their effects on the upper atmosphere ever conducted.

Data collected by AWE will enable scientists to determine the physics and characteristics of atmospheric gravity waves and how terrestrial weather influences the ionosphere, which can affect communication with satellites. Credit: NASA’s Goddard Space Flight Center Conceptual Image Lab As a payload headed to the space station, AWE was required to hold four crucial safety reviews. The mission was successfully certified as a station payload at its last review in July 2023. Part of this certification involved “sharp edge” testing with astronaut gloves to ensure safety during AWE’s installation and maintenance on the exterior of the space station. AWE is the first NASA mission to attempt this type of science to provide insight into how terrestrial and space weather interactions may affect satellite communications and tracking in orbit. Following AWE’s installation on the International Space Station, the team’s focus will be to share the instrument’s data and results with the science community and the public.
