As we continue to celebrate Hispanic Heritage Month, the NASA Office of Small Business Programs is pleased to share the contributions of Bastion Technologies Inc. (Bastion), a Hispanic-owned company that supports NASA’s missions. Their primary role is in Safety & Mission Assurance at NASA’s Marshall Space Flight Center in Huntsville, Alabama. This includes systems engineering, where they have worked on design and analysis activities for the International Space Station, space shuttle, and Artemis programs. Bastion engages in critical assessments to ensure the highest standards of safety and reliability in NASA missions. Their team provides mission assurance support for both crewed and uncrewed flight systems at various other NASA centers such as Stennis Space Center, Ames Research Center, Glenn Research Center, and NASA’s Jet Propulsion Laboratory. In addition to supporting the success of NASA missions, they have prioritized the safety of our astronauts and valuable payloads. As a result, Bastion has received the Marshall Space Flight Center Safety Award for maintaining an exemplary safety record, with 2 million work hours without any injuries.  NASA has also recognized Bastion with the Space Flight Awareness Award for their role in multiple aspects of the Space Launch Program, particularly in ensuring the successful delivery and launch of the Artemis I launch vehicle.  During Artemis I, NASA’s SLS (Space Launch System), soared into the sky and sent the Orion spacecraft on a 1.4-million-mile journey beyond the Moon and back. The Space Launch System is NASA’s heavy-lift rocket and serves as the cornerstone for human exploration beyond Earth’s orbit. The SLS is the only rocket capable of sending the Orion spacecraft, four astronauts, and transporting extensive cargo directly to the Moon within a single mission.  Liftoff! NASA’s Space Launch System carrying the Orion spacecraft lifts off the pad at Launch Complex 39B at the agency’s Kennedy Space Center in Florida at 1:47 a.m. EST on Nov. 16, 2022. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown. a They have also aided in a 12-test series of the new RS-25 engines at the agency’s Stennis Space Center in Mississippi, which are integral to future SLS rocket missions. For over three decades, the RS-25 engine powered the space shuttle, completing 135 missions. This engine stands as one of the most rigorously tested large rocket engines in history, with over 3,000 starts and an accumulated firing time exceeding 1 million seconds through ground tests and flight. Throughout the Space Shuttle Program, the RS-25 underwent numerous design enhancements aimed at improving durability, reliability, safety, and performance. Four RS-25 engines attached to the core stage for Artemis I Furthermore, Bastion’s assistance in projects such as the Sample Cartridge Assembly and Copper Indium Sulfide Defect Growth  has been critical in completing the CISDG-C1 hardware for shipment and launch on the 28th SpaceX commercial resupply services mission for NASA. It launched to the International Space Station from the agency’s Kennedy Space Center in Florida on June 3, 2023.  On this mission, SpaceX’s Dragon spacecraft transported several thousand pounds of essential hardware,  scientific experiments, and technology demonstrations. It also encompassed research on plant stress adaptation, investigations into genetic structures known as telomeres, as well as the deployment of satellite projects designed by Canadian students.  Embed Video: https://youtu.be/KMB9fvH-EsM Lastly, Bastion’s contribution to the Life Science Glovebox payload has seen a significant increase, with them completing 2.5 times as many integrated safety assessments in 2023 as they did in 2022. The Life Sciences Glovebox is a sealed work area in the International Space Station  which provides bioisolation and waste control. Crew members can perform experimental procedures in cell, insect, aquatic, plant, and animal developmental biology. NASA’s new Life Sciences Glovebox undergoes testing at Marshall prior to its scheduled Sept. 10 flight to the International Space Station. The research facility is 26 inches high, 35 inches wide and 24 inches deep, with a 15-cubic-foot workspace.NASA/MSFC/Steve Moon Hispanic professional continues to influence his daily work with NASA and Bastion in profound ways. “Growing up in a culturally rich and diverse background, I have brought a unique perspective to problem-solving and teamwork. I’ve learned to adapt to different challenges and appreciate the value of diversity in the workplace,” says Hernandez.   He goes on to emphasize that Bastion actively supports mentorship and advocates for underrepresented minorities in STEM fields, aiming to inspire the next generation of diverse professionals to reach for the stars.  “Bastion’s journey supporting NASA has been deeply influenced by my heritage, which has driven our company to excel and promote diversity within the agency.

Environmental Portrait of Jennifer L. Turner for Faces of NASA Project. NASA / James Blair “I can almost directly trace my entire career back to [my extracurriculars] in high school and a mentor I had. My first foray into engineering was this high school program called the Robotics Science Academy. It was basically my high school’s attempt to put together a curriculum that was designed specifically to prepare students for an engineering track in college. But since it was the first year of trying this program, there were only about eight of us. The high school teacher leading the robotics track, Mr. Donelson, was always [encouraging] about trying new things and getting out of our comfort zone. And I think that always really helped me.” “So I owe a lot to him, for sure. He would stay after school with us and walk us through our assignments, and ended up encouraging us to enter an underwater robotics competition. Because we were fairly landlocked – which is obviously not great for underwater robotics that are meant for deep sea missions — we sort of lucked our way into the international competition.” “Even so, we ended up winning a “bang for your buck” award based on the amount of tasks we completed in the mission and the cost of our robot, because the cost was very, very low. It was just this Frankenstein monstrosity of PVC pipes and messy high schooler soldering and wiring. But no matter how it looked, I was lucky to have teachers like Mr. Donelson to push all of us forward.” Image Credit: NASA / James Blair Check out some of our other Faces of NASA.

On Oct. 1, 1958, the National Aeronautics and Space Administration (NASA) officially began operations. President Dwight D. Eisenhower signed into law the National Aeronautics and Space Act the previous July, creating NASA to lead America’s civilian space program in response to Soviet advances in space exploration. T. Keith Glennan and Hugh L. Dryden were sworn in as NASA’s first administrator and deputy administrator, respectively. As its core, the new agency incorporated the National Advisory Committee for Aeronautics (NACA), founded in 1915 to advance aeronautics research in the United States. The NACA elements included three large research laboratories and two small test facilities. Projects and facilities transferred from other agencies to augment NASA’s capabilities. Within days of opening, NASA began work on America’s first human spaceflight program. Left: NASA Deputy Administrator Hugh L. Dryden, left, introduces NASA Administrator T. Keith Glennan as he prepares to deliver a filmed address to NACA employees about the impending transition to NASA. Middle: The Dolley Madison House on LaFayette Square in Washington, D.C., NASA’s first headquarters building. Right: The main entrance to the Dolley Madison House. In a filmed address delivered to all NACA employees shortly before the transition, Glennan explained that the change to the new organization should not affect their daily lives, even though the new agency would over time take on more responsibilities. Indeed, the transition for the existing 8,000 NACA employees proved rather seamless. They went home on Sept. 30 as NACA employees and reported for work on Oct. 1 as NASA employees, without change to their daily routines. On Oct. 1, Glennan addressed the 170-member headquarters staff in the courtyard of the Dolley Madison House on Lafayette Square in Washington, D.C., that served as NASA’s first headquarters.

Three NACA research laboratories – Langley Aeronautical Laboratory in Hampton, Virginia; Ames Aeronautical Laboratory in Mountain View, California; and Lewis Flight Propulsion Laboratory in Cleveland, Ohio – and two small test facilities – the Muroc Dry Lake in California’s high desert for high-speed flight research, and one for sounding rockets at Wallops Island in Virginia – transferred to NASA on Oct. 1, with a total of 8,000 employees and an annual budget of $100 million. By Dec. 31, 1958, NASA had absorbed elements of the Army Ballistic Missile Agency in Huntsville, Alabama, the Naval Research Laboratory in Washington, D.C., including its Project Vanguard, and the Jet Propulsion Laboratory in Pasadena, California, a contractor facility operated by the California Institute of Technology. These added 420 employees and 2,300 contractors to the workforce and brought the agency’s appropriations to more than $330 million. It also acquired a high-priority rocket engine development project from the U.S. Air Force. Over time, the Agency established or incorporated additional centers and facilities to meet the growing needs of the nation’s space program. Today, 10 field centers across the nation work together to accomplish NASA’s varied missions. Left: The headquarters building for the Space Task Group at NASA’s Langley Research Center in Hampton, Virginia. Middle: An early cutaway representation of a Mercury capsule. Right: An early representation of rocket engines for human spaceflight, including the F-1 at right. President Eisenhower gave NASA overall responsibility for developing America’s human spaceflight program. The new agency inherited two large top priority projects in this arena. The first involved developing a spacecraft capable of carrying a single human into space and returning him safely to Earth. Engineers at Langley had conducted studies in this area since 1952, and on Oct. 8, 1958, Glennan gave the formal approval for the formation of a team at Langley to develop this capability. On Nov. 5, the Space Task Group (STG) formally came into existence, with Robert R. Gilruth named as project manager and Charles J. Donlan as his assistant. Thanks to their previous work, the STG released the specifications for the crewed capsule on Nov. 14, mailing them three days later to 20 prospective companies that had expressed an interest in bidding on the project that NASA formally named Project Mercury on Nov. 26. On Jan. 9, 1959, NASA selected the McDonnell Aircraft Corporation of St. Louis to develop the spacecraft. The second major high-priority project involved the development of a 1.5-million-pound thrust rocket engine to power a future large space booster. The new agency inherited studies conducted by the U.S. Air Force, and by mid-December, NASA selected the Rocketdyne Division of North American Aviation to develop the F-1 engine that later powered the Saturn V moon rocket. Left: Pioneer 1 shortly before its launch on a Thor-Able rocket. Middle: Replica of Pioneer 1 on display at the Smithsonian Institute’s Steven F. Udvar-Hazy Center in Chantilly, Virginia. Image credit: courtesy National Air and Space Museum. Right: Engineers inspect Pioneer 3 before launch. The nearly identical Pioneer 4 became the first American spacecraft to reach solar orbit. The new agency inherited satellite programs from other agencies. The first of these, part of a program of lunar orbiters inherited from the U.S. Air Force, launched on Oct. 11, 1958, under the auspices of NASA although the Air Force conducted the operations. Pioneer 1 blasted off aboard a Thor-Able rocket from a fledgling launch facility at Cape Canaveral, Florida. Although it did not achieve its intended mission to orbit the Moon due to a rocket malfunction, Pioneer 1 did reach a then record altitude of about 70,000 miles. The probe returned scientific data confirming the existence of the Van Allen radiation belts until it burned up on reentry in the Earth’s atmosphere 43 hours after launch. Two other Pioneers met similar fates in November and December. Pioneer 4, although it missed the Moon, became the first American spacecraft to enter solar orbit in March 1959. In the subsequent decades, NASA launched spacecraft to unlock the mysteries of the universe, dispatched probes to make close up observations of every planet in the solar system, sent men on voyages to the Moon, built a space station to maintain a permanent human presence in space, and today is preparing to return astronauts to the Moon.

When the asteroid Psyche has its first close-up with a NASA spacecraft, scientists hypothesize they will find a metal-rich asteroid. It could be part or all of the iron-rich interior of a planetesimal, an early planetary building block, that was stripped of its outer rocky shell as it repeatedly collided with other large bodies during the early formation of the solar system. New research from scientists at NASA’s Ames Research Center in California’s Silicon Valley suggests that is exactly what the agency’s Psyche mission will find. An artist’s concept depicting the metal-rich asteroid Psyche, which is located in the main asteroid belt between Mars and Jupiter. NASA/JPL-Caltech/ASU Led by Anicia Arredondo, the paper’s first author and a postdoctoral researcher at the Southwest Research Institute in San Antonio, Texas, and Maggie McAdam, Ames research scientist and principal investigator, the team observed Psyche in Feb. 2022 using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA). The now-retired observatory was a Boeing 747SP aircraft modified to carry a reflecting telescope. As a flying telescope, SOFIA collected data that was not affected by Earth’s lower atmosphere and made observations from all over the world, including over the oceans. For the first time, SOFIA was able to gather data from every part of Psyche’s surface. It also allowed the team to collect data about the materials that make up Psyche’s surface – information that could not be gathered from ground-based telescopes. Psyche’s potential to answer many questions about planet formation is a key reason why it was selected for close observation by a spacecraft. Scientists believe that planets like Earth, Mars, and Mercury have metallic cores, but they are buried too far below the planets’ mantles and crusts to see or measure directly. If Psyche is confirmed to be a planetary core, it can help scientists understand what is inside the Earth and other large planetary bodies. Psyche’s size is also important for advancing scientific understanding of Earth-like planets. It is the largest M-type (metallic) asteroid in our solar system and is long enough to cover the distance from New York City to Baltimore, Maryland. This means Psyche is more likely to show differentiation, which is when the materials inside a planet separate from one another, with the heaviest materials sinking to the middle and forming cores. “Every time a new study of Psyche is published, it raises more questions,” said Arredondo, who was a postdoctoral researcher at Ames on the SOFIA mission when the Psyche observations were collected. “Our findings suggest the asteroid is very complex and likely holds many other surprises. The possibility of the unexpected is one of the most exciting parts of a mission to study an unexplored body, and we look forward to gaining a more detailed understanding of Psyche’s origins.” NASA’s Psyche spacecraft is shown in a clean room on June 26, 2023, at the Astrotech Space Operations facility near the agency’s Kennedy Space Center in Florida.NASA/Frank Michaux More about the Psyche and SOFIA missions: Arizona State University leads the Psyche mission. A division of Caltech in Pasadena, JPL is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis. Psyche is the 14th mission selected as part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. NASA’s Launch Services Program, based at Kennedy, is managing the launch service. SOFIA was a joint project of NASA and the German Space Agency at DLR. DLR provided the telescope, scheduled aircraft maintenance, and other support for the mission. NASA’s Ames Research Center in California’s Silicon Valley managed the SOFIA program, science, and mission operations in cooperation with the Universities Space Research Association, headquartered in Columbia, Maryland, and the German SOFIA Institute at the University of Stuttgart. The aircraft was maintained and operated by NASA’s Armstrong Flight Research Center Building 703, in Palmdale, California. SOFIA achieved full operational capability in 2014 and concluded its final science flight on Sept. 29, 2022.

NASA astronaut Scott Kelly took this majestic image of the Earth at night highlighting the green and red hues of an Aurora. NASA NASA is asking American companies to provide input on the agency’s requirements for end-to-end services as part of the Commercial Low-Earth Orbit Development Program. In the future, the agency plans to transition its operations in low Earth orbit to commercially owned and operated destinations to ensure continued access and presence in space for research, technology development, and international collaboration after the planned retirement of the International Space Station. Through a request for information (RFI), NASA is seeking feedback from industry as the agency refines its anticipated requirements for new commercial space destinations. The requirements will help industry understand NASA’s human-rating standards that will be used by the agency to certify that the new systems meet NASA expectations for low Earth orbit operations and transportation. An industry briefing day is scheduled to take place Tuesday Oct. 12, with responses to the RFI due Wednesday, Nov. 17. “This RFI is a significant next step in transitioning low Earth orbit operations to the private sector, allowing NASA to be one of many customers for services” says Phil McAlister, director of commercial spaceflight at NASA Headquarters in Washington, D.C. “These requirements will be the foundation upon which the companies can design safe systems. But the requirements have to work for companies as well. Thus, we are seeking industry feedback on these draft requirements to ensure that the Commercial LEO destinations will be safe, reliable, and cost effective.” The agency is currently supporting the development of several new stations and destination concepts through both funded and unfunded agreements. However, a company does not need to have a current agreement with NASA in order to provide feedback via the RFI or to bid on future procurements to provide low Earth orbit services to the agency. “We’ve seen a tremendous amount of innovation and effort from industry thus far in developing their station designs,” says Angela Hart, manager of the Commercial Low Earth Orbit Development program at NASA’s Johnson Space Center in Houston. “We are working in lockstep with multiple companies to help guide them in a way that sets them up for success to meet our requirements. However, it’s crucial that we open feedback to as wide of an audience as possible. The more commercial stations that are successfully operating in low Earth orbit, the greater likelihood that we can continue to drive down costs and encourage innovation in this new commercial space industry.” NASA previously sought industry input in 2022 and early 2023, and has hosted two industry days on the agency’s assumptions and expectations for crew and technical requirements to guide companies’ technical and business plans. The feedback from industry will continue to inform the agency’s future commercial services strategy for low Earth orbit destinations. NASA’s goal is to enable a strong commercial marketplace in low Earth orbit where NASA is one of many customers for private industry. This strategy will provide services the government needs safely, at a lower cost, and enables the agency to focus on its Artemis missions to the Moon in preparation for Mars, while continuing to use low Earth orbit as a training and proving ground for those deep space missions. Information about how to attend the industry briefing day is contained in the RFI on SAM.gov. The dates for industry day and responses due are subject to change pending a government shutdown resolution and will be updated on SAM.gov when available.

2 min read Hubble Views A Vibrant Virgo Cluster Galaxy NASA’s Hubble Space Telescope, ESA, and J. Lee (Space Telescope Science Institute); Processing: Gladys Kober (NASA/Catholic University of America) It’s easy to get swept up in the swirling starry arms of this intermediate spiral galaxy, NGC 4654, in the constellation Virgo. The galaxy has a bright center and is labeled “intermediate” because it has characteristics of both unbarred and barred spirals. NGC 4654 is just north of the celestial equator, making it visible from the northern hemisphere and most of the southern hemisphere. The galaxy is around 55 million light-years from Earth. NGC 4654 is one of many Virgo Cluster galaxies that have an asymmetric distribution of stars and of neutral hydrogen gas. Astronomers reason that NGC 4654 may be experiencing a process called “ram pressure stripping,” where the gravitational pull of the Virgo galaxy cluster puts pressure on NGC 4654 as it moves through a superheated plasma made largely of hydrogen called the “intracluster medium.” This pressure feels like a gust of wind – think of a biker feeling wind even on a still day – that strips NGC 4654 of its gas. This process produced a long, thin tail of hydrogen gas on the galaxy’s southeastern side. Most galaxies that experienced ram pressure stripping hold very little cold gas, halting the galaxy’s ability to form new stars, since stars generate from dense gas. However, NGC 4654 has star formation rates consistent with other galaxies of its size. NGC 4654 also had an interaction with the companion galaxy NGC 4639 about 500 million years ago. The gravity of NGC 4639 stripped NGC 4654’s gas along its edge, limiting star formation in that region and causing the asymmetrical distribution of the galaxy’s stars. Scientists study galaxies like NGC 4654 to examine the connection between young stars and the cold gas from which they form. NASA’s Hubble Space Telescope took this image in visible, ultraviolet, and infrared light.

Our First Asteroid Sample Return Mission is Back on Earth on This Week @NASA – September 29, 2023

Discovery Alert: The Planet that Shouldn’t Be There Artist’s rendering of planet 8 Ursae Minoris b – also known as “Halla” – amid the field of debris after a violent merger of two stars. The planet might have survived the merger, but also might be an entirely new planet formed from the debris. W. M. Keck Observatory/Adam Makarenko By Pat Brennan NASA’s Exoplanet Exploration Program The discovery: A large planet is somehow orbiting a star that should have destroyed it. Key facts: Planet 8 Ursae Minoris b orbits a star some 530 light-years away that is in its death throes. A swollen red giant, the star would have been expected to expand beyond the planet’s orbit before receding to its present (still giant) size. In other words, the star would have engulfed and ripped apart any planets orbiting closely around it. Yet the planet remains in a stable, nearly circular orbit. The discovery of this seemingly impossible situation, relying on precise measurements using NASA’s Transiting Exoplanet Survey Satellite (TESS), shows that planet formation – and destruction – are likely far more intricate and unpredictable than many scientists might have thought. Details: As stars like our Sun approach the ends of their lives, they begin to exhaust their nuclear fuel. They become red giants, expanding to their maximum size. If that happened in this case, the star would have grown outward from its center to 0.7 astronomical units – that is, about three-quarters the distance from Earth to the Sun. It would have swallowed and destroyed any nearby orbiting planets in the process. But planet b, a large gaseous world, sits at about 0.5 astronomical units, or AU. Because the planet could not have survived engulfment, Marc Hon, the lead author of a recent paper on the discovery, instead proposes two other possibilities: The planet is really the survivor of a merger between two stars, or it’s a new planet – formed out of the debris left behind by that merger. The first scenario begins with two stars about the size of our Sun in close orbit around each other, the planet orbiting both. One of the stars “evolves” a bit faster than the other, going through its red giant phase, casting off its outer layers and turning into a white dwarf – the tiny but high-mass remnant of a star. The other just reaches the red giant stage before the two collide; what remains is the red giant we see today. This merger, however, stops the red giant from expanding further, sparing the orbiting planet from destruction. In the second scenario, the violent merger of the two stars ejects an abundance of dust and gas, which forms a disk around the remaining red giant. This “protoplanetary” disk provides the raw material for a new planet to coalesce. It’s a kind of late-stage second life for a planetary system – though the star still is nearing its end. Fun facts: How can astronomers infer such a chaotic series of events from present-day observations? It all comes down to well understood stellar physics. Planet-hunting TESS also can be used to observe the jitters and quakes on distant stars, and these follow known patterns during the red-giant phase. (Tracking such oscillations in stars is known as “asteroseismology.”) The pattern of oscillations on 8 Ursae Minoris, the discovery team found, match those of red giants at a late, helium-burning stage – not one that is still expanding as it burns hydrogen. So it isn’t that the star is still growing and hasn’t yet reached the planet. The crisis has come and gone, but the planet somehow continues to exist. The discoverers: The paper describing the TESS result, “A close-in giant planet escapes engulfment by its star,” was published in the journal Nature in June 2023 by an international science team led by astronomer Marc Hon of the University of Hawaii.

NASA logoCredits: NASA NASA has selected four small explorer missions to conduct concept studies. These studies aim to expand knowledge of the dynamics of the Sun and related phenomena, such as coronal mass ejections, aurora, and solar wind to better understand the Sun-Earth connection. Any missions selected to move forward after the concept studies are conducted will join the current heliophysics mission fleet, which not only provides deeper insight into the mechanics of our universe, but also offers critical information to help protect astronauts, satellites, and communications signals, and helps enable space exploration. “These four mission concept studies were selected because they address compelling science questions and could greatly impact the field of heliophysics,” said Nicky Fox, the associate administrator for science at NASA Headquarters in Washington. “These mission proposals are exciting because they build upon and complement the science of our current mission fleet, have the potential for broad impact and could provide new and deeper insight into the solar atmosphere and space weather.” CINEMA The Cross-scale Investigation of Earth’s Magnetotail and Aurora (CINEMA) mission would work to understand the structure and evolution of Earth’s plasma sheet – a long sheet of denser space plasma in the magnetic fields flowing behind Earth, known as the magnetotail — using a constellation of nine CubeSats flown in sun-synchronous, low Earth orbit. The primary purpose of this mission is to study the role of plasma sheet structure, as well as how Earth’s magnetic fields transfer heat and change over time at multiple scales. CINEMA will complement current heliophysics missions, such as the THEMIS (Time History of Events and Macroscale Interactions during Substorms), MMS (Magnetospheric Multiscale) mission, and the planned Geospace Dynamics Constellation mission. The principal investigator for the CINEMA mission concept study is Robyn Millan from Dartmouth College, in Hanover, New Hampshire. CMEx The Chromospheric Magnetism Explorer (CMEx) mission would attempt to understand the magnetic nature of solar eruptions and identify the magnetic sources of the solar wind. CMEx proposes to obtain the first continuous observations of the solar magnetic field in the chromosphere – the layer of solar atmosphere directly above the photosphere or visible surface of the Sun. These observations would improve our understanding of how the magnetic field on the Sun’s surface connects to the interplanetary magnetic field. The principal investigator for this mission concept study is Holly Gilbert from the National Center for Atmospheric Research in Boulder, Colorado. EUV CME and Coronal Connectivity Observatory The Extreme ultraviolet Coronal Mass Ejection and Coronal Connectivity Observatory (ECCCO) consists of a single spacecraft with two instruments, a wide-field extreme ultra-violet imager and a unique imaging EUV spectrograph. ECCCO’s observations would contribute to understanding the middle corona, the dynamics of eruptive events leaving the Sun, and the conditions that produce the outward streaming solar wind. The mission would address fundamental questions about where the mass and energy flow linking the Sun to the outer corona and heliosphere originate ECCCO’s concept study principal investigator is Katharine Reeves from the Smithsonian Astrophysical Observatory, in Cambridge, Massachusetts. MAAX The primary objective of the Magnetospheric Auroral Asymmetry Explorer (MAAX) mission would be to improve our understanding of how electrodynamic coupling between Earth’s magnetosphere and ionosphere regulates auroral energy flow. The mission would use two identical spacecraft equipped with dual-wavelength ultraviolet imagers to provide global imaging of northern and southern aurora. The principal investigator for the MAAX concept study is Michael Liemohn from the University of Michigan in Ann Arbor. “These mission concept study selections provide so much promise to ongoing heliophysics research,” said Peg Luce, acting Heliophysics division director at NASA Headquarters. “The potential to gain new insights and answer longstanding questions in the field while building on the research and technology of our current and legacy missions is incredible..” Funding and management oversight for these mission concept studies is provided by the Heliophysics Explorers Program, managed by the Explorers Program Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

SpaceX’s Dragon will deliver new science investigations, food, supplies, and equipment to the international crew. The research includes work to understand interactions between weather on Earth and space, and laser communications. NASA’s Atmospheric Waves Experiment (AWE) will study atmospheric gravity waves –powerful waves formed by weather disturbances on Earth such as strong thunderstorms or brewing hurricanes – to understand the flow of energy through Earth’s upper atmosphere and space. Another experiment – Integrated Laser Communications Relay Demonstration Low-Earth-Orbit User Modem and Amplifier Terminal – (ILLUMA-T) aims to test high data rate laser communications from the space station to Earth. This will complete NASA’s first two-way, end-to-end laser relay system by sending high-resolution data to the agency’s Laser Communications Relay Demonstration, which launched in December 2021. Other investigations that will launch with the resupply mission include ESA’s (European Space Agency) Aquamembrane-3, which will test water filtration using proteins found in nature for water recycling and recovery, and Plant Habitat-06, which will evaluate the effects of spaceflight on plant defense responses using multiple genotypes of tomato. Commercial resupply by U.S. companies significantly increases NASA’s ability to conduct more investigations aboard the orbiting laboratory. These investigations lead to new technologies, medical treatments, and products that improve life on Earth. Other U.S. government agencies, private industry, and academic and research institutions can also conduct microgravity research through the agency’s partnership with the International Space Station National Laboratory. Humans have occupied the space station continuously since November 2000. In that time, 273 people and a variety of international and commercial spacecraft have visited the orbital outpost. It remains the springboard to NASA’s next great leap in exploration, including future missions to the Moon under Artemis, and ultimately, human exploration of Mars.

NASA logo Credit: NASA NASA has selected SpaceX of Hawthorne, California, and its Falcon 9 rocket to provide the launch service for the agency’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission, a pair of small satellites that will study space weather and how the Sun’s energy affects Earth’s magnetic environment, or magnetosphere TRACERS will be an important addition to NASA’s heliophysics fleet and aims to answer long-standing questions critical to understanding the Sun-Earth system. The spinning satellites will study how solar wind, the continuous stream of ionized particles escaping the Sun and pouring out to space, interacts with the region around Earth dominated by our planet’s magnetic field. This interaction, or magnetic reconnection, is an intense transfer of energy that can happen when two magnetic fields meet, which could potentially impact operations with crew and sensitive satellites. TRACERS is led by the University of Iowa with partners at the Southwest Research Institute in San Antonio, and Millennium Space Systems in El Segundo, California. NASA’s Launch Services Program, based out of the agency’s Kennedy Space Center in Florida, in partnership with NASA’s Heliophysics Small Explorers program, announces the launch service as part of the agency’s VADR (Venture-Class Acquisition of Dedicated and Rideshare) launch services contract.

5 min read To Study Atmosphere, NASA Rockets Will Fly into Oct. Eclipse’s Shadow A NASA sounding rocket mission will launch three rockets during the 2023 annular eclipse in October to study how the sudden drop in sunlight affects our upper atmosphere. On Oct. 14, 2023, viewers of an annular solar eclipse in the Americas will experience the Sun dimming to 10% its normal brightness, leaving only a bright “ring of fire” of sunlight as the Moon eclipses the Sun. Those in the vicinity of the White Sands Missile Range in New Mexico, however, might also notice sudden bright streaks across the sky: trails of scientific rockets, hurtling toward the eclipse’s shadow. A NASA sounding rocket mission will launch three rockets to study how the sudden drop in sunlight affects our upper atmosphere. The mission, known as Atmospheric Perturbations around the Eclipse Path or APEP, is led by Aroh Barjatya, a professor of engineering physics at Embry-Riddle Aeronautical University in Daytona Beach, Florida, where he directs the Space and Atmospheric Instrumentation Lab. Some 50 miles up and beyond, the air itself becomes electric. Scientists call this atmospheric layer the ionosphere because it is where the UV component of sunlight can pry electrons away from atoms to form a sea of high-flying ions and electrons. The Sun’s constant energy keeps these mutually attracted particles separated throughout the day. But as the Sun dips below the horizon, many recombine into neutral atoms for the night, only to part ways again at sunrise. During a solar eclipse, the sunlight vanishes and reappears over a small part of the landscape almost at once. In a flash, ionospheric temperature and density drop, then rise again, sending waves rippling through the ionosphere. “If you think of the ionosphere as a pond with some gentle ripples on it, the eclipse is like a motorboat that suddenly rips through the water,” Barjatya said. “It creates a wake immediately underneath and behind it, and then the water level momentarily goes up as it rushes back in.” The animation shows the changes in the number of electrons (total electron content or TEC) in the ionosphere over the US during the 2017 eclipse. Overlaid on the measurements are the contours that represent location of the outer shadow of the eclipse as it moves across the sky. Credit: Mrak, S., Semeter, J., Drob, D., & Huba, J. D. (2018).

Geophysical Research Letters, 45(9), 3820-3828. https://doi.org/10.1029/2017GL076771 During the 2017 total solar eclipse visible across North America, instruments many hundreds of miles outside the eclipse’s path detected atmospheric changes. So did critical infrastructure like GPS and communications satellites that we rely on every day. “All satellite communications go through the ionosphere before they reach Earth,” Barjatya said. “As we become more dependent on space-based assets, we need to understand and model all perturbations in the ionosphere.” Aroh Barjatya, of Embry-Riddle Aeronautic University in Daytona Beach, Florida, leads the APEP mission. Here, Barjatya inspects the subpayloads, which will eject from the rocket mid-flight. The subpayloads carry the plasma density, neutral density, and magnetic field sensors.

It was said that Apep pursued Ra and every so often nearly consumed him, resulting in an eclipse. The APEP team plans to launch three rockets in succession – one about 35 minutes before local peak eclipse, one during peak eclipse, and one 35 minutes after. They will fly just outside the path of annularity, where the Moon passes directly in front of the Sun. Each rocket will deploy four small scientific instruments that will measure changes in electric and magnetic fields, density, and temperature. If they are successful, these will be the first simultaneous measurements taken from multiple locations in the ionosphere during a solar eclipse. Barjatya chose sounding rockets to answer the team’s science questions because they can pinpoint and measure specific regions of space with high fidelity. They can also measure changes that happen at different altitudes as the suborbital rocket ascends and falls back to Earth. The APEP rockets will take measurements between 45 and 200 miles (70 to 325 kilometers) above the ground along their trajectory. “Rockets are the best way to look at the vertical dimension at the smallest possible spatial scales,” said Barjatya. “They can wait to launch at just the right moment and explore the lower altitudes where satellites can’t fly.” While the in-situ rocket instruments are all being built by Embry-Riddle and Dartmouth College in New Hampshire, a host of ground-based observations will also support the mission. Co-investigators from the Air Force Research Laboratory at Kirtland Air Force Base in Albuquerque, New Mexico, will collect ionospheric density and neutral wind measurements. Co-investigators from the Massachusetts Institute of Technology’s Haystack Observatory in Westford, Massachusetts, will run their radar to measure ionospheric perturbations farther away from the eclipse path. Finally, a team of students from Embry-Riddle will deploy high-altitude balloons (reaching 100,000 feet) every 20 minutes to measure weather changes as the eclipse passes by. All of these measurements will aid ionosphere modeling efforts led by scientists at the University of Colorado Boulder and Embry-Riddle. This won’t be the only APEP launch. The APEP rockets launched in New Mexico will be recovered and then relaunched from NASA’s Wallops Flight Facility in Virginia, on April 8, 2024, when a total solar eclipse will cross the U.S. from Texas to Maine. The April launches are farther from the eclipse path than for the October annular eclipse, but will present an opportunity to measure just how widespread the effects of an eclipse are. This map details the path the Moon’s shadow will take as it crosses the contiguous U.S. during the annular solar eclipse on Oct. 14, 2023, and total solar eclipse on April 8, 2024. Credit: NASA/Scientific Visualization Studio/Michala Garrison; eclipse calculations by Ernie Wright After these two eclipses, the next total solar eclipse over the contiguous U.S. is not until 2044, and the next annular eclipse is not until 2046. “We have to make hay while the Sun shines … or, I suppose for eclipse science, while it doesn’t,” Barjatya joked. “In all seriousness though, this data set will reveal the widespread effects that eclipses have on the ionosphere at the smallest spatial scales.” Read More APEP mission fact sheet Learn more about the upcoming eclipses View the full article

In celebration of National Hispanic Heritage Month, the NASA Office of Small Business Programs (OSBP) is highlighting the contributions made by Hispanic-owned businesses to NASA’s mission. Through collaborative efforts, Patriot Construction, Inc. has played a pivotal role in the enhancement and maintenance of NASA’S Ames Research Center in California. They have worked on the N244 Seismic Risk Reduction, Restore Reliability of Main Switchboard for Agency Telecom Gateway N254, Historic Preservation of Building 025 Phase 2 of 2, and the N258 Hyperwall Room Remodeling. This outdoor display of the Unitary Plan Wind Tunnel (UPWT), on DeFrance Ave at Ames Research Center, was updated in August 2023. The display will inform the visiting public of the contributions this National Historic Landmark has made to the Nation’s aeronautical research. The projects Patriot have been involved in, Buildings N244, N254, N258 are critical buildings to NASA missions. The Restore Reliability of Main Switchboard for Agency Telecom Gateway N254 project is an upgrade to their main switchboard. This building is an essential 24/7 operation that holds the Security Operations Center (SOC) which is the nerve center for detection and monitoring of security incidents for the Agency. The N258 Hyperwall Room Remodeling is a dedicated space equipped with a hyperwall, accessible to all users NASA Supercomputer users. The Supercomputer is available to every mission directorate in NASA. Additionally, the hyperwall significantly increases efficiency, allowing wind tunnel personnel to conduct analyses more quickly. The Historic Preservation of Building 025 Phase 2 of 2 is a historical building which NASA is restoring to make it ready for occupancy. Building 025 has not received maintenance since the Navy’s departure in 1998. In accordance with the National Historic Preservation Act (NHPA), NASA, as a federal agency, has a responsibility to preserve and maintain the historical integrity of all properties under its jurisdiction. The N244 Seismic Risk Reduction project is a proactive initiative aimed at ensuring the safety of all personnel within building N244 during earthquakes.
