Liftoff! NASA’s Europa Clipper Sails Toward Ocean Moon of Jupiter

NASA’s Europa Clipper has embarked on its long voyage to Jupiter, where it will investigate Europa, a moon with an enormous subsurface ocean that may have conditions to support life. The spacecraft launched at 11:06 a.m. CDT on Oct. 14 aboard a SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center.

After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.

The largest spacecraft NASA ever built for a mission headed to another planet, Europa Clipper also is the first NASA mission dedicated to studying an ocean world beyond Earth. The spacecraft will travel 1.8 billion miles on a trajectory that will leverage the power of gravity assists, first to Mars in four months and then back to Earth for another gravity assist flyby in 2026. After it begins orbiting Jupiter in April 2030, the spacecraft will fly past Europa 49 times.

“Congratulations to our Europa Clipper team for beginning the first journey to an ocean world beyond Earth,” said NASA Administrator Bill Nelson. “NASA leads the world in exploration and discovery, and the Europa Clipper mission is no different. By exploring the unknown, Europa Clipper will help us better understand whether there is the potential for life not just within our solar system, but among the billions of moons and planets beyond our Sun.”

Approximately five minutes after liftoff, the rocket’s second stage fired up and the payload fairing, or the rocket’s nose cone, opened to reveal Europa Clipper. About an hour after launch, the spacecraft separated from the rocket. Ground controllers received a signal soon after, and two-way communication was established at 12:13 p.m. with NASA’s Deep Space Network facility in Canberra, Australia. Mission teams celebrated as initial telemetry reports showed Europa Clipper is in good health and operating as expected.

“We could not be more excited for the incredible and unprecedented science NASA’s Europa Clipper mission will deliver in the generations to come,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters. “Everything in NASA science is interconnected, and Europa Clipper’s scientific discoveries will build upon the legacy that our other missions exploring Jupiter – including Juno, Galileo, and Voyager – created in our search for habitable worlds beyond our home planet.”

The main goal of the mission is to determine whether Europa has conditions that could support life. Europa is about the size of our own Moon, but its interior is different. Information from NASA’s Galileo mission in the 1990s showed strong evidence that under Europa’s ice lies an enormous, salty ocean with more water than all of Earth’s oceans combined. Scientists also have found evidence that Europa may host organic compounds and energy sources under its surface.

If the mission determines Europa is habitable, it may mean there are more habitable worlds in our solar system and beyond than imagined.

“We’re ecstatic to send Europa Clipper on its way to explore a potentially habitable ocean world, thanks to our colleagues and partners who’ve worked so hard to get us to this day,” said Laurie Leshin, director, NASA’s Jet Propulsion Laboratory (JPL). “Europa Clipper will undoubtedly deliver mind-blowing science. While always bittersweet to send something we’ve labored over for years off on its long journey, we know this remarkable team and spacecraft will expand our knowledge of our solar system and inspire future exploration.”

In 2031, the spacecraft will begin conducting its science-dedicated flybys of Europa. Coming as close as 16 miles to the surface, Europa Clipper is equipped with nine science instruments and a gravity experiment, including an ice-penetrating radar, cameras, and a thermal instrument to look for areas of warmer ice and any recent eruptions of water. As the most sophisticated suite of science instruments NASA has ever sent to Jupiter, they will work in concert to learn more about the moon’s icy shell, thin atmosphere, and deep interior.

To power those instruments in the faint sunlight that reaches Jupiter, Europa Clipper also carries the largest solar arrays NASA has ever used for an interplanetary mission. With arrays extended, the spacecraft spans 100 feet from end to end. With propellant loaded, it weighs about 13,000 pounds.

In all, more than 4,000 people have contributed to Europa Clipper mission since it was formally approved in 2015.

“As Europa Clipper embarks on its journey, I’ll be thinking about the countless hours of dedication, innovation, and teamwork that made this moment possible,” said Jordan Evans, project manager, JPL. “This launch isn’t just the next chapter in our exploration of the solar system; it’s a leap toward uncovering the mysteries of another ocean world, driven by our shared curiosity and continued search to answer the question, ‘are we alone?’”

Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.

Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center, Marshall Space Flight Center, and Langley Research Center. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.

NASA’s Launch Services Program, based at NASA Kennedy, managed the launch service for the Europa Clipper spacecraft.

Black Hole Destroys Star, Goes After Another, NASA Missions Find

NASA’s Chandra X-ray Observatory and other telescopes have identified a supermassive black hole that has torn apart one star and is now using that stellar wreckage to pummel another star or smaller black hole, as described in our latest press release. This research helps connect two cosmic mysteries and provides information about the environment around some of the bigger types of black holes.

This artist’s illustration shows a disk of material (red, orange, and yellow) that was created after a supermassive black hole (depicted on the right) tore apart a star through intense tidal forces. Over the course of a few years, this disk expanded outward until it intersected with another object – either a star or a small black hole – that is also in orbit around the giant black hole. Each time this object crashes into the disk, it sends out a burst of X-rays detected by Chandra. The inset shows Chandra data (purple) and an optical image of the source from Pan-STARRS (red, green, and blue).

In 2019, an optical telescope in California noticed a burst of light that astronomers later categorized as a “tidal disruption event”, or TDE. These are cases where black holes tear stars apart if they get too close through their powerful tidal forces. Astronomers gave this TDE the name of AT2019qiz.

Meanwhile, scientists were also tracking instances of another type of cosmic phenomena occasionally observed across the Universe. These were brief and regular bursts of X-rays that were near supermassive black holes. Astronomers named these events “quasi-periodic eruptions,” or QPEs.

This latest study gives scientists evidence that TDEs and QPEs are likely connected. The researchers think that QPEs arise when an object smashes into the disk left behind after the TDE. While there may be other explanations, the authors of the study propose this is the source of at least some QPEs.

In 2023, astronomers used both Chandra and Hubble to simultaneously study the debris left behind after the tidal disruption had ended. The Chandra data were obtained during three different observations, each separated by about 4 to 5 hours. The total exposure of about 14 hours of Chandra time revealed only a weak signal in the first and last chunk, but a very strong signal in the middle observation.

From there, the researchers used NASA’s Neutron Star Interior Composition Explorer (NICER) to look frequently at AT2019qiz for repeated X-ray bursts. The NICER data showed that AT2019qiz erupts roughly every 48 hours. Observations from NASA’s Neil Gehrels Swift Observatory and India’s AstroSat telescope cemented the finding.

The ultraviolet data from Hubble, obtained at the same time as the Chandra observations, allowed the scientists to determine the size of the disk around the supermassive black hole. They found that the disk had become large enough that if any object was orbiting the black hole and took about a week or less to complete an orbit, it would collide with the disk and cause eruptions.

This result has implications for searching for more quasi-periodic eruptions associated with tidal disruptions. Finding more of these would allow astronomers to measure the prevalence and distances of objects in close orbits around supermassive black holes. Some of these may be excellent targets for the planned future gravitational wave observatories.

The paper describing these results appears in the Oct. 9 issue of the journal Nature. The first author of the paper is Matt Nicholl of Queen’s University Belfast in Ireland.

Revealing the Hidden Universe with Full-shell X-ray Optics at Marshall

The study of X-ray emission from astronomical objects reveals secrets about the universe at the largest and smallest spatial scales. Celestial X-rays are produced by black holes consuming nearby stars, emitted by the million-degree gas that traces the structure between galaxies, and can be used to predict whether stars may be able to host planets hospitable to life. X-ray observations have shown that most of the visible matter in the universe exists as hot gas between galaxies and have conclusively demonstrated that the presence of “dark matter” is needed to explain galaxy cluster dynamics, that dark matter dominates the mass of galaxy clusters, and that it governs the expansion of the cosmos.

The X-ray image from the Chandra X-ray Observatory (blue and white), reveals exquisite details in the central ring structures and gas flowing out of the polar jets. Optical light from the Hubble Space Telescope (purple) shows foreground and background stars as pinpoints of light. Infrared light from the Spitzer Space Telescope (pink) traces cooler gas in the nebula. Finally, magnetic field direction derived from X-ray polarization observed by the Imaging X-ray Polarimetry Explorer is shown as orange lines.

X-ray observations also enable us to probe mysteries of the universe on the smallest scales. X-ray observations of compact objects such as white dwarfs, neutron stars, and black holes allow us to use the universe as a physics laboratory to study conditions that are orders of magnitude more extreme in terms of density, pressure, temperature, and magnetic field strength than anything that can be produced on Earth. In this astrophysical laboratory, researchers expect to reveal new physics at the subatomic scale by conducting investigations such as probing the neutron star equation of state and testing quantum electrodynamics with observations of neutron star atmospheres.

At NASA’s Marshall Space Flight Center, a team of scientists and engineers is building, testing, and flying innovative optics that bring the universe’s X-ray mysteries into sharper focus.

Unlike optical telescopes that create images by reflecting or refracting light at near-90-degree angles (normal incidence), focusing X-ray optics must be designed to reflect light at very small angles (grazing incidence). At normal incidence, X-rays are either absorbed by the surface of a mirror or penetrate it entirely. However, at grazing angles of incidence, X-rays reflect very efficiently due to an effect called total external reflection. In grazing incidence, X-rays reflect off the surface of a mirror like rocks skipping on the surface of a pond.

A classic design for astronomical grazing incidence optics is the Wolter-I prescription, which consists of two reflecting surfaces, a parabola and hyperbola (see figure below). This optical prescription is revolved around the optical axis to produce a full-shell mirror (i.e., the mirror spans the full circumference) that resembles a gently tapered cone. To increase the light collecting area, multiple mirror shells with incrementally larger diameters and a common focus are fabricated and nested concentrically to comprise a mirror module assembly (MMA).

Focusing optics are critical to studying the X-ray universe because, in contrast to other optical systems like collimators or coded masks, they produce high signal-to-noise images with low background noise. Two key metrics that characterize the performance of X-ray optics are angular resolution, which is the ability of an optical system to discriminate between closely spaced objects, and effective area, which is the light collecting area of the telescope, typically quoted in units of cm2. Angular resolution is typically measured as the half-power diameter (HPD) of a focused spot in units of arcseconds. The HPD encircles half of the incident photons in a focused spot and measures the sharpness of the final image; a smaller number is better.

Parallel rays of light enter from the left, reflect twice off the reflective inside surface of the shell (first off the parabolic segment and then off the hyperbolic segment), and converge at the focal plane.

Marshall has been building and flying lightweight, full-shell, focusing X-ray optics for over three decades, always meeting or exceeding angular resolution and effective area requirements. Marshall utilizes an electroformed nickel replication technique to make these thin full-shell X-ray optics from nickel alloy.

X-ray optics development at Marshall began in the early 1990s with the fabrication of optics to support NASA’s Advanced X-ray Astrophysics Facility (AXAF-S) and then continued via the Constellation-X technology development programs. In 2001, Marshall launched a balloon payload that included two modules each with three mirrors, which produced the first focused hard X-ray images of an astrophysical source by imaging Cygnus X-1, GRS 1915, and the Crab Nebula. This initial effort resulted in several follow-up missions over the next 12 years and became known as the High Energy Replicated Optics (HERO) balloon program.

In 2012, the first of four sounding rocket flights of the Focusing Optics X-ray Solar Imager (FOXSI) flew with Marshall optics onboard, producing the first focused images of the Sun at energies greater than 5 keV. In 2019 the Astronomical Roentgen Telescope X-ray Concentrator (ART-XC) instrument on the Spectr-Roentgen-Gamma Mission launched with seven Marshall-fabricated X-ray MMAs, each containing 28 mirror shells. ART-XC is currently mapping the sky in the 4-30 keV hard X-ray energy range, studying exotic objects like neutron stars in our own galaxy as well as active galactic nuclei, which are spread across the visible universe. In 2021, the Imaging X-ray Polarimetry Explorer (IXPE), flew and is now performing extraordinary science with a Marshall-led team using three, 24-shell MMAs that were fabricated and calibrated in-house.

Most recently, in 2024, the fourth FOXSI sounding rocket campaign launched with a high-resolution Marshall MMA. The optics achieved 9.5 arcsecond HPD angular resolution during pre-flight test with an expected 7 arcsecond HPD in gravity-free flight, making this the highest angular resolution flight observation made with a nickel-replicated X-ray optic. Currently Marshall is fabricating an MMA for the Rocket Experiment Demonstration of a Soft X-ray (REDSoX) polarimeter, a sounding rocket mission that will fly a novel soft X-ray polarimeter instrument to observe active galactic nuclei. The REDSoX MMA optic will be 444 mm in diameter, which will make it the largest MMA ever produced by MSFC and the second largest replicated nickel X-ray optic in the world.

The ultimate performance of an X-ray optic is determined by errors in the shape, position, and roughness of the optical surface. To push the performance of X-ray optics toward even higher angular resolution and achieve more ambitious science goals, Marshall is currently engaged in a fundamental research and development effort to improve all aspects of full-shell optics fabrication.

Given that these optics are made with the electroformed nickel replication technique, the fabrication process begins with creation of a replication master, called the mandrel, which is a negative of the desired optical surface. First, the mandrel is figured and polished to specification, then a thin layer of nickel alloy is electroformed onto the mandrel surface. Next, the nickel alloy layer is removed to produce a replicated optical shell, and finally the thin shell is attached to a stiff holding structure for use.

Each step in this process imparts some degree of error into the final replicated shell. Research and development efforts at Marshall are currently concentrating on reducing distortion induced during the electroforming metal deposition and release steps. Electroforming-induced distortion is caused by material stress built into the electroformed material as it deposits onto the mandrel. Decreasing release-induced distortion is a matter of reducing adhesion strength between the shell and mandrel, increasing strength of the shell material to prevent yielding, and reducing point defects in the release layer.

Additionally, verifying the performance of these advanced optics requires world-class test facilities. The basic premise of testing an optic designed for X-ray astrophysics is to place a small, bright X-ray source far away from the optic. If the angular size of the source, as viewed from the optic, is smaller than the angular resolution of the optic, the source is effectively simulating X-ray starlight. Due to the absorption of X-rays by air, the entire test facility light path must be placed inside a vacuum chamber.

At the center, a group of scientists and engineers operate the Marshall 100-meter X-ray beamline, a world-class end-to-end test facility for flight and laboratory X-ray optics, instruments, and telescopes. As per the name, it consists of a 100-meter-long vacuum tube with an 8-meter-long, 3-meter-diameter instrument chamber and a variety of X-ray sources ranging from 0.25 – 114 keV. Across the street sits the X-Ray and Cryogenic Facility (XRCF), a 527-meter-long beamline with an 18-meter-long, 6-meter-diameter instrument chamber. These facilities are available for the scientific community to use and highlight the comprehensive optics development and test capability that Marshall is known for.

Within the X-ray astrophysics community there exist a variety of angular resolution and effective area needs for focusing optics. Given its storied history in X-ray optics, Marshall is uniquely poised to fulfill requirements for large or small, medium- or high-angular-resolution X-ray optics. To help guide technology development, the astrophysics community convenes once per decade to produce a decadal survey. The need for high-angular-resolution and high-throughput X-ray optics is strongly endorsed by the National Academies of Sciences, Engineering, and Medicine report, Pathways to Discovery in Astronomy and Astrophysics for the 2020s.In pursuit of this goal, Marshall is continuing to advance the state of the art in full-shell optics. This work will enable the extraordinary mysteries of the X-ray universe to be revealed.

Hubble, New Horizons Team Up for a Simultaneous Look at Uranus

NASA’s Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study like types of planets around other stars.

Astronomers used Uranus as a proxy for similar planets beyond our solar system, known as exoplanets, comparing high-resolution images from Hubble to the more-distant view from New Horizons. This combined perspective will help scientists learn more about what to expect while imaging planets around other stars with future telescopes.

“While we expected Uranus to appear differently in each filter of the observations, we found that Uranus was actually dimmer than predicted in the New Horizons data taken from a different viewpoint,” said lead author Samantha Hasler of the Massachusetts Institute of Technology in Cambridge and New Horizons science team collaborator.

Direct imaging of exoplanets is a key technique for learning about their potential habitability, and offers new clues to the origin and formation of our own solar system. Astronomers use both direct imaging and spectroscopy to collect light from the observed planet and compare its brightness at different wavelengths. However, imaging exoplanets is a notoriously difficult process because they’re so far away. Their images are mere pinpoints and so are not as detailed as the close-up views that we have of worlds orbiting our Sun. Researchers can also only directly image exoplanets at “partial phases,” when only a portion of the planet is illuminated by their star as seen from Earth.

Uranus was an ideal target as a test for understanding future distant observations of exoplanets by other telescopes for a few reasons. First, many known exoplanets are also gas giants similar in nature. Also, at the time of the observations, New Horizons was on the far side of Uranus, 6.5 billion miles away, allowing its twilight crescent to be studied – something that cannot be done from Earth. At that distance, the New Horizons view of the planet was just several pixels in its color camera, called the Multispectral Visible Imaging Camera.

On the other hand, Hubble, with its high resolution, and in its low-Earth orbit 1.7 billion miles away from Uranus, was able to see atmospheric features such as clouds and storms on the day side of the gaseous world.

“Uranus appears as just a small dot on the New Horizons observations, similar to the dots seen of directly imaged exoplanets from observatories like Webb or ground-based observatories,” Hasler said. “Hubble provides context for what the atmosphere is doing when it was observed with New Horizons.”

The gas giant planets in our solar system have dynamic and variable atmospheres with changing cloud cover. How common is this among exoplanets? By knowing the details of what the clouds on Uranus looked like from Hubble, researchers can verify what is interpreted from the New Horizons data. In the case of Uranus, both Hubble and New Horizons saw that the brightness did not vary as the planet rotated, which indicates that the cloud features were not changing with the planet’s rotation.

In this image, two three-dimensional shapes, top, of Uranus are compared to the actual views of the planet from NASA's Hubble Space Telescope, bottom left, and NASA's New Horizon's spacecraft, bottom right. Comparing high-resolution images from Hubble to the smaller view from New Horizons offers a combined perspective that will help researchers learn more about what to expect while imaging planets around other stars with future observatories.

However, the importance of the detection by New Horizons has to do with how the planet reflects light at a different phase than what Hubble, or other observatories on or near Earth, can see. New Horizons showed that exoplanets may be dimmer than predicted at partial and high phase angles, and that the atmosphere reflects light differently at partial phase.

NASA has two major upcoming observatories in the works to advance studies of exoplanet atmospheres and potential habitability.

“These landmark New Horizons studies of Uranus from a vantage point unobservable by any other means add to the mission’s treasure trove of new scientific knowledge, and have, like many other datasets obtained in the mission, yielded surprising new insights into the worlds of our solar system,” added New Horizons principal investigator Alan Stern of the Southwest Research Institute.

NASA’s upcoming Nancy Grace Roman Space Telescope, set to launch by 2027, will use a coronagraph to block out a star’s light to directly see gas giant exoplanets. NASA’s Habitable Worlds Observatory, in an early planning phase, will be the first telescope designed specifically to search for atmospheric biosignatures on Earth-sized, rocky planets orbiting other stars.

“Studying how known benchmarks like Uranus appear in distant imaging can help us have more robust expectations when preparing for these future missions,” concluded Hasler. “And that will be critical to our success.”

Launched in January 2006, New Horizons made the historic flyby of Pluto and its moons in July 2015, before giving humankind its first close-up look at one of these planetary building block and Kuiper Belt object, Arrokoth, in January 2019. New Horizons is now in its second extended mission, studying distant Kuiper Belt objects, characterizing the outer heliosphere of the Sun, and making important astrophysical observations from its unmatched vantage point in distant regions of the solar system.

The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

The Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, built and operates the New Horizons spacecraft and manages the mission for NASA’s Science Mission Directorate. Southwest Research Institute, based in San Antonio and Boulder, Colorado, directs the mission via Principal Investigator Alan Stern and leads the science team, payload operations and encounter science planning. New Horizons is part of NASA’s New Frontiers program, managed by NASA’s Marshall Space Flight Center.

NASA and SpaceX mission managers are watching unfavorable weather conditions off the Florida coast right now for the splashdown of the SpaceX Crew-8 mission with NASA astronauts Matthew DominickMike Barratt, and Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin. The homebound quartet spent Oct. 14 mostly relaxing while also continuing departure preps. Mission teams are currently targeting Dragon Endeavour’s undocking for no earlier than 2:05 a.m. CDT on Oct. 18. The Crew-8 foursome is in the seventh month of their space research mission that began on March 3.

The other seven orbital residents will stay aboard the orbital outpost until early 2025. NASA astronaut Don Pettit is scheduled to return to Earth first in February with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner aboard the Soyuz MS-26 crew ship. Next, station Commander Suni Williams and flight engineer Butch Wilmore are targeted to return home aboard SpaceX Dragon Freedom with SpaceX Crew-9 Commander Nick Hague, all three NASA astronauts, and Roscosmos cosmonaut Aleksandr Gorbunov.

Williams had a light duty day Oct. 14 disassembling life support gear before working out for a cardio fitness study. Wilmore installed a new oxygen recharge tank and began transferring oxygen into tanks located in the Quest airlock. Hague collected his blood and saliva samples for incubation and cold stowage to learn how microgravity affects cellular immunity. Pettit also had a light duty day servicing biology hardware including the Cell Biology Experiment Facility, a research incubator with an artificial gravity generator, and the BioLab, which supports observations of microbes, cells, tissue cultures and more.

The Huntsville Operations Support Center (HOSC) at NASA’s Marshall Space Flight Center provides engineering and mission operations support for the space station, the CCP, and Artemis missions, as well as science and technology demonstration missions. The Payload Operations Integration Center within HOSC operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day.

The first flight of Sierra Space’s Dream Chaser to the space station is now scheduled for no earlier than May 2025 to allow for completion of spacecraft testing. Dream Chaser, which will launch atop a ULA (United Launch Alliance) Vulcan rocket and later glide to a runway landing at NASA’s Kennedy Space Center, will carry cargo to the orbiting laboratory and stay on board for approximately 45 days on its first mission.

      NASA’s Ames Research Center Celebrates 85 Years of Innovation
      by Rachel Hoover
      Ames Research Center in California’s Silicon Valley pre-dates a lot of things. The center existed before NASA – the very space and aeronautics agency it’s a critical part of today. And of all the marvelous advancements in science and technology that have fundamentally changed our lives over the last 85 years since its founding, one aspect has remained steadfast; an enduring commitment to what’s known by some on-center simply as, “an atmosphere of freedom.” 
      The NACA Ames laboratory in 1944.Image credit: NASA Years before breaking ground at the site that would one day become home to the world’s preeminent wind tunnels, supercomputers, simulators, and brightest minds solving some of the world’s toughest challenges, Joseph Sweetman Ames, the center’s namesake, described a sentiment that would guide decades of innovation and research: 
      “My hope is that you have learned or are learning a love of freedom of thought and are convinced that life is worthwhile only in such an atmosphere,” he said in an address to the graduates of Johns Hopkins University in June 1935.
      That spirit and the people it attracted and retained are a crucial part of how Ames, along with other N.A.C.A. research centers, ultimately made technological breakthroughs that enabled humanity’s first steps on the Moon, the safe return of spacecraft through Earth’s atmosphere, and many other discoveries that benefit our day-to-day lives.
      Russell Robinson momentarily looks to the camera while supervising the first excavation at what would become Ames Research Center.Image credit: NACA “In the context of my work, an atmosphere of freedom means the freedom to pursue high-risk, high-reward, innovative ideas that may take time to fully develop and — most importantly — the opportunity to put them into practice for the benefit of all,” said Edward Balaban, a researcher at Ames specializing in artificial intelligence, robotics, and advanced mission concepts.
      Balaban’s career at Ames has involved a variety of projects at different stages of development – from early concept to flight-ready – including experimenting with different ways to create super-sized space telescopes in space and using artificial intelligence to help guide the path a rover might take to maximize off-world science results. Like many Ames researchers over the years, Balaban shared that his experience has involved deep collaborations across science and engineering disciplines with colleagues all over the center, as well as commercial and academic partners in Silicon Valley where Ames is nestled and beyond. This is a tradition that runs deep at Ames and has helped lead to entirely new fields of study and seeded many companies and spinoffs.
      Before NASA, Before Silicon Valley: The 1939 Founding of Ames Aeronautical Laboratory “In the fields of aeronautics and space exploration the cost of entry can be quite high. For commercial enterprises and universities pursuing longer term ideas and putting them into practice often means partnering up with an organization such as NASA that has the scale and multi-disciplinary expertise to mature these ideas for real-world applications,” added Balaban.
      “Certainly, the topics of inquiry, the academic freedom, and the benefit to the public good are what has kept me at Ames,” reflected Ross Beyer, a planetary scientist with the SETI Institute at Ames. “There’s not a lot of commercial incentive to study other planets, for example, but maybe there will be soon. In the meantime, only with government funding and agencies like NASA can we develop missions to explore the unknown in order to make important fundamental science discoveries and broadly share them.”
      For Beyer, his boundary-breaking moment came when he searched – and found – software engineers at Ames capable and passionate about open-source software to generate accurate, high-resolution, texture-mapped, 3D terrain models from stereo image pairs. He and other teams of NASA scientists have since applied that software to study and better understand everything from changes in snow and ice characteristics on Earth, as well as features like craters, mountains, and caves on Mars or the Moon. This capability is part of the Artemis campaign, through which NASA will establish a long-term presence at the Moon for scientific exploration with commercial and international partners. The mission is to learn how to live and work away from home, promote the peaceful use of space, and prepare for future human exploration of Mars. 
      “As NASA and private companies send missions to the Moon, they need to plan landing sites and understand the local environment, and our software is freely available for anyone to use,” Beyer said. “Years ago, our management could easily have said ‘No, let’s keep this software to ourselves; it gives us a competitive advantage.’ They didn’t, and I believe that NASA writ large allows you to work on things and share those things and not hold them back.” 
      When looking forward to what the next 85 years might bring, researchers shared a belief that advancements in technology and opportunities to innovate are as expansive as space itself, but like all living things, they need a healthy atmosphere to thrive. Balaban offered, “This freedom to innovate is precious and cannot be taken for granted. It can easily fall victim if left unprotected. It is absolutely critical to retain it going forward, to ensure our nation’s continuing vitality and the strength of the other freedoms we enjoy.”

      Ames Aeronautical Laboratory.Image credit: NACA Today Marks the Retirement of the Astrogram Newsletter
      by Astrid Albaugh
      For 66 years, the Astrogram has told the story of NASA’s Ames Research Center. Over those six-plus decades, the newsletter has documented hundreds of missions led by Ames, the progression of Hangar One’s reclamation, space shuttle launches with Ames’ payloads aboard them, countless VIP visits, and everything in between.
      Ames published the first edition of the Astrogram in October 1958, coinciding with the transition of the center from its original incarnation as the National Advisory Committee for Aeronautics Ames Aeronautical Laboratory to a National Aeronautics and Space Administration (NASA) research center.
      The newsletter has evolved over time, alongside the center. From October 1958 through January 2016, the Astrogram was published in print, before a digital edition was developed. In January 2016, the Astrogram transitioned to a digital-only format. Below are examples of some of the Astrogram issues from over the years. More are forthcoming from 1998 and prior once they are retrieved from the archives.
      October 2014 Astrogram September 2010 Astrogram I have served as the editor of the Astrogram since February 1998. Over the past quarter century, it has been an interesting, and sometimes quite challenging, task for me to capture the breadth and depth of Ames’s story and ensure that we always published the newsletter on time. I still remember trekking over to the center’s imaging office to review the physical negatives and images that the Ames photographers had taken of events onsite and select the most compelling photos. I used a very early version of visual design software to craft the layout. When the paper was completed, I’d file it onto a CD and then hand it to the courier who would drive from the San Francisco printshop to pick it up from me. Once and awhile, someone would request to have an additional feature added, requiring multiple trips up the 101 and back. Sometimes I’d come in on the weekends to work on the paper, due to late submissions, much to the chagrin of my kids.
      July 2007 Astrogram It has been a pleasure serving as the editor over the past quarter century, almost as many years as my kids are old. A person once asked me if I had changed my name to Astrid since it’s so like the word Astrogram. Any relationship between the newsletter and my name is simply serendipity. I have enjoyed being behind the scenes, mostly working diligently at my computer. Many at Ames know my name because of the newsletter but may have never met me in person. It’s been amusing sometimes when I encounter someone who can’t put a finger as to why they knew my name but didn’t recognize me standing in front of them. Their usual response when they realized why they know me was, “Ah, Astrid of the Astrogram.”
      March 20, 1998 Astrogram Just as NASA innovates, the content of the Astrogram has to innovate as well. Many of the stories that you used to read in the Astrogram, you can now find on our NASA Ames web page here. If you would like to access past, archived issues of the Astrogram, going back to 1958, please consult the Ames Research Center Archives. I will continue to help tell Ames’s story, just using new platforms.
      Whether this is your first issue or you have been an Astrogram supporter for decades, thank you for reading!

      A method for evaluating thermophysical properties of metal alloys

      Simulation of the solidification of metal alloys, a key step in certain industrial processes, requires reliable data on their thermophysical properties such as surface tension and viscosity. Researchers propose comparing predictive models with experimental outcomes as a method to assess these data.

      Scientists use data on surface tension and viscosity of titanium-based alloys in industrial processes such as casting and crystal growth. Non-Equilibrium Solidification, Modelling for Microstructure Engineering of Industrial Alloys, an ESA (European Space Agency) investigation, examined the microstructure and growth of these alloys using the station’s Electromagnetic Levitator. This facility eliminates the need for containers, which can interfere with experiment results.
      European Space Agency (ESA) astronaut Alexander Gerst is shown in the Columbus module of the International Space Station during the installation of the Electromagnetic Levitator.ESA/Alexander Gerst Overview of techniques for measuring thermal diffusion

      Researchers present techniques for measuring thermal diffusion of molecules in a mixture. Thermal diffusion is measured using the Soret coefficient – the ratio of movement caused by temperature differences to overall movement within the system. This has applications in mineralogy and geophysics such as predicting the location of natural resources beneath Earth’s surface.

      A series of ESA investigations studied diffusion, or how heat and particles move through liquids, in microgravity. Selectable Optical Diagnostics Instrument-Influence of VIbrations on DIffusion of Liquids examined how vibrations affect diffusion in mixtures with two components and SODI-DCMIX measured more-complex diffusion in mixtures of three or more components. Understanding and predicting the effects of thermal diffusion has applications in various industries such as modeling of underground oil reservoirs.

      Researchers validated the concept of using ferrofluid technology to operate a thermal control switch in a spacecraft. This outcome could support development of more reliable and long-lasting spacecraft thermal management systems, increasing mission lifespan and improving crew safety.

      Überflieger 2: Ferrofluid Application Research Goes Orbital analyzed the performance of ferrofluids, a technology that manipulates components such as rotors and switches using magnetized liquids and a magnetic field rather than mechanical systems, which are prone to wear and tear. This technology could lower the cost of materials for thermal management systems, reduce the need for maintenance and repair, and help avoid equipment failure. The paper discusses possible improvements to the thermal switch, including optimizing the geometry to better manage heat flow.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA/Quincy Eggert NASA’s Armstrong Flight Research Center in Edwards, California, is preparing today for tomorrow’s mission. Supersonic flight, next generation aircraft, advanced air mobility, climate changes, human exploration of space, and the next innovation are just some of the topics our researchers, engineers, and mission support teams focused on in 2024.
      NASA Armstrong began 2024 with the public debut of the X-59 quiet supersonic research aircraft. Through the unique design of the X-59, NASA aims to reduce the sonic boom to make it much quieter, potentially opening the future to commercial supersonic flight over land. Throughout the first part of the year, NASA and international researchers studied air quality across Asia as part of a global effort to better understand the air we breathe. Later in the year, for the first time, a NASA-funded researcher conducted an experiment aboard a commercial suborbital rocket, studying how changes in gravity during spaceflight affect plant biology.
      Here’s a look at more NASA Armstrong accomplishments throughout 2024:
      Our simulation team began work on NASA’s X-66 simulator, which will use an MD-90 cockpit and allow pilots and engineers to run real-life scenarios in a safe environment. NASA Armstrong engineers completed and tested a model of a truss-braced wing design, laying the groundwork for improved commercial aircraft aerodynamics. NASA’s Advanced Air Mobility mission and supporting projects worked with industry partners who are building innovative new aircraft like electric air taxis. We explored how these new designs may help passengers and cargo move between and inside cities efficiently. The team began testing with a custom virtual reality flight simulator to explore the air taxi ride experience. This will help designers create new aircraft with passenger comfort in mind. Researchers also tested a new technology that will help self-flying aircraft avoid hazards. A NASA-developed computer software tool called OVERFLOW helped several air taxi companies predict aircraft noise and aerodynamic performance. This tool allows manufacturers to see how new design elements would perform, saving the aerospace industry time and money. Our engineers designed a camera pod with sensors at NASA Armstrong to help advance computer vision for autonomous aviation and flew this pod at NASA’s Kennedy Space Center in Florida. NASA’s Quesst mission marked a major milestone with the start of tests on the engine that will power the quiet supersonic X-59 experimental aircraft. In February and March, NASA joined international researchers in Asia to investigate pollution sources. The now retired DC-8 and NASA Langley Gulfstream III aircraft collected air measurements over the Philippines, South Korea, Malaysia, Thailand, and Taiwan. Combined with ground and satellite observations, these measurements continue to enrich global discussions about pollution origins and solutions. The Gulfstream IV joined NASA Armstrong’s fleet of airborne science platforms. Our teams modified the aircraft to accommodate a next-generation science instrument that will collect terrain information of the Earth in a more capable, versatile, and maintainable way. The ER-2 and the King Air supported the development of spaceborne instruments by testing them in suborbital settings. On the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment mission (PACE-PAX), the ER-2 validated data collected by the PACE satellite about the ocean, atmosphere, and surfaces. Operating over several countries, researchers onboard NASA’s C-20A collected data and images of Earth’s surface to understand global ecosystems, natural hazards, and land surface changes. Following Hurricane Milton, the C-20A flew over affected areas to collect data that could help inform disaster response in the future. We also tested nighttime precision landing technologies that safely deliver spacecraft to hazardous locations with limited visibility. With the goal to improve firefighter safety, NASA, the U.S. Forest Service, and industry tested a cell tower in the sky. The system successfully provided persistent cell coverage, enabling real-time communication between firefighters and command posts. Using a 1960s concept wingless, powered aircraft design, we built and tested an atmospheric probe to better and more economically explore giant planets. NASA Armstrong hosted its first Ideas to Flight workshop, where subject matter experts shared how to accelerate research ideas and technology development through flight. These are just some of NASA Armstrong’s many innovative research efforts that support NASA’s mission to explore the secrets of the universe for the benefit of all.
