Artemis II Crew Enjoys Visit with Marshall Team Members

By Wayne Smith

From talking about continuing the legacy of NASA’s Marshall Space Flight Center in space exploration to describing their roles in an upcoming historic mission, Artemis II astronauts enjoyed visiting with center team members Nov. 27.

The crew will be the first to ride aboard NASA’s SLS (Space Launch System) rocket and Orion spacecraft. They will launch atop the rocket to venture around the Moon on Artemis II, the first crewed flight for Artemis. Their mission around the Moon will verify capabilities for humans to explore deep space and pave the way for long-term exploration and science on the lunar surface. Marshall manages the SLS Program.

The four-member crew answered questions from a standing-room only crowd for about an hour inside Activities Building 4316 before taking photos with Marshall team members. The crew consists of NASA astronauts Reid Wiseman, who will be the Artemis II commander, Victor Glover (pilot) and Christina Koch (mission specialist), and Canadian Space Agency astronaut Jeremy Hansen (mission specialist).

They even took the time to send a personalized Christmas greeting to the grandmother of Corey Walker, an atmospheric science programmer at Marshall with Jacobs, who said it would be the perfect gift for her. During the question and answer portion of the event, the astronauts had Walker join them on stage and made a short greeting for his grandmother, Brenda Lowery, who lives on Sand Mountain.

“I can’t wait to give this to her because she loves the space program,” Walker said. “She was young when the astronauts went to the Moon the first time. She has lots of mementos at her house of the space program.”

After acting Center Director Joseph Pelfrey welcomed team members to the event, SLS Program Manager John Honeycutt talked about Marshall’s reputation of excellence in rocket propulsion and the success of Artemis I before introducing the astronauts.

“Since the beginning, NASA astronauts have launched on historic missions and on rockets designed, developed, and built right here at Marshall Space Flight Center and our Michoud Assembly Facility,” Honeycutt said. “… It seems only fitting that when a new era of human space flight launches on a rocket developed here, that that’s the way it should be. We’ve been entrusted not just with an incredibly powerful and capable rocket, but with the lives of four astronauts. Their safety and return are chief among our responsibilities.”

Wiseman acknowledged Marshall’s rocket excellence, but also pointed out the center’s role in research for future missions to the Moon and working in the lunar environment. The Payload Operations Integration Center at Marshall is the control center for scientific operations on the International Space Station.

“(Marshall) means a lot more to us than getting us off this planet,’ Wiseman said. “It’s also our human research side when we are off the planet. When we are working sustainably in the lunar area, and we see humans on Mars, it’s built on the shoulders of POIC (Payload Operations Integration Center), of human research in orbit. That is the bread and butter of what we’re doing. We’re launching humans and living in space, and that is built right here at Marshall.”

Glover, who will be the first African American on a lunar mission, thanked Marshall team members for their work with SLS and the space station. He spent 168 days in space as a flight engineer aboard the space station for Expedition 64.

“Thank you for your work supporting our friends who are working on the space station now and for that amazing legacy that we’ve all had the opportunity to be a part of in one facet or another,” Glover said. “We’re here to do the work and be a part of this team. We hope that what we’re doing makes you proud.”

Koch and Hansen also will make history with the Artemis II mission. Koch will be the first woman on a lunar mission, while Hansen will be the first Canadian.

Andy Buehler, a rocket propulsion engineer at Marshall with Boeing, asked Koch what her message to young girls is as they see a female going to the Moon for the first time.

“Surround yourself with people who are encouraging,” Koch said. “Tell yourself you’re going to do great things one day. You can be that voice for yourself. Don’t just strive to be a part of something, strive to be excellent at what you’re doing.”

Corey Walker, an atmospheric science programmer at Marshall with Jacobs, smiles with the astronauts as they record a video wishing Walker’s grandmother, Brenda Lowery, merry Christmas. During a question and answer session with the astronauts, Walker asked if he could get a video of them for his grandmother as a Christmas gift for her. Walker said his grandmother loves the space program. At far left is Lance D. Davis, Marshall’s news chief, who served as moderator for the event.

Hansen said he is excited about the future of Artemis. He told Marshall team members they are part of something that brings value to the world with NASA’s leadership.

“You’re doing that with partners around the world because you’re choosing to lead,” Hansen said. “We need that kind of leadership and that vision more than ever. We really need to be focused on things that lift up humanity. We have a lot of reason for hope for our future.”

Artemis II astronauts Victor Glover, Reid Wiseman, and Christina Koch of NASA, and CSA (Canadian Space Agency) astronaut Jeremy Hansen signed the Orion stage adapter for the SLS (Space Launch System) rocket at NASA’s Marshall Space Flight Center on Nov. 27. The hardware is the topmost portion of the SLS rocket that they will launch atop during Artemis II when the four astronauts inside NASA’s Orion spacecraft will venture around the Moon.

The Orion stage adapter is a small ring structure that connects NASA’s Orion spacecraft to the SLS rocket’s interim cryogenic propulsion stage and fully manufactured at Marshall. At five feet tall and weighing 1,800 pounds, the adapter is the smallest major element of the SLS rocket. During Artemis II, the adapter’s diaphragm will serve as a barrier to prevent gases created during launch from entering the spacecraft.

NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission. Through Artemis, NASA will explore more of the lunar surface than ever before and prepare for the next giant leap: sending astronauts to Mars.

Monthly Brown Bag Seminars Shine Spotlight on Marshall’s Business Units

By Jessica Barnett

With thousands of employees across hundreds of departments and teams, there’s no shortage of cool things happening at NASA’s Marshall Space Flight Center. To help keep Marshall team members up to date, the center recently started a series of monthly brown bag seminars aimed at highlighting its business units.

Each month features a different business unit. On Nov. 7, nearly 300 Marshall team members attended the first seminar, which focused on Marshall’s Moon/Mars Surface Technologies and Systems. In doing so, the participants learned more about the center’s strategy.

“We’re in between the hopes and dreams of what you might find out there or what the vision of the future on the lunar surface might look like, and what is actually practical,” said Michael Zanetti, a lunar and planetary geologist at Marshall who was also one of the speakers during the Nov. 7 seminar.

Zanetti discussed GPS-denied LiDAR navigation systems, including KNaCK (Kinematic Navigation and Cartography Knapsack), a proof-of-concept 3D terrain mapping, navigation, and algorithm development tool that can be used to determine the layout of portions of the lunar or Martian surface even when there is no light source or GPS to guide it.

He also talked about Marshall’s Lunar Regolith Terrain Facility – a 125-by-125-foot area covered in 500 tons of lunar regolith simulant that can be quickly modified as needed for robotics testing.

“If we’re going to send anything to the lunar surface, we need to make sure that technology is going to be able to function when it gets there,” said Jennifer Edmunson, project manager for Marshall’s Moon-to-Mars Planetary Autonomous Construction Technology Project, or MMPACT. “Testing with regolith is important to do that, but since we don’t have enough regolith material from the Apollo missions, we rely on simulants.”

Materials test engineer Annette Gray, far left at table, explains how participants in Marshall’s MERCRII (Metallic Environmentally Resistant Coatings Rapid Innovation Initiative) worked with other centers and NASA partners to develop a radiation-resistant coating to improve the wear resistance of mechanism joints on the lunar or Martian surface.

MMPACT is currently working to determine how best to build infrastructure on the lunar surface using the regolith and resources already available there. Edmunson shared how the project aims to build landing pads and even habitats on the Moon, but that it’s important to find ways of building that can withstand the extreme temperature variations, lengthy moonquakes, and other challenges that would be faced on the lunar surface.

Joining Edmunson and Zanetti at the seminar was Annette Gray, a materials test engineer who was part of MERCRII (Metallic Environmentally Resistant Coatings Rapid Innovation Initiative). Gray explained how the early career initiative project worked with other centers and NASA partners to develop a radiation-resistant coating to improve the wear resistance of mechanism joints on the lunar or Martian surface.

Part of the initiative included acquiring a Planetary, Lunar, and Asteroid Natural Environment Testbed, or PLANET. Gray said the PLANET was a 2-meter-by-3-meter chamber with up to 1 ton of regolith simulant inside that could test high vacuum, low-density plasma, and various atmospheric conditions.

The seminar ended with a question-and-answer session and a chance for in-person attendees to check out regolith simulant samples.

“It was an excellent way to showcase how the varied work we do at Marshall is enabling future NASA missions and addressing critical gaps,” said MMSTS Strategy Lead Shawn Maynor. “The excitement was palpable, and the discussion was lively. I truly feel that Marshall is in a unique position to capitalize on the evolving space industry.”

The next brown bag seminar is set for January 2024, after the winter holiday season.

NASA Releases Its First International Space Station Tour in Spanish

Lee esta nota de prensa en español aquí.

Record-breaking NASA astronaut Frank Rubio provides the agency’s first Spanish-language video tour of humanity’s home in space – the International Space Station.

Rubio welcomes the public aboard the microgravity science laboratory in a behind-the-scenes look at living and working in space recorded during his 371-day mission aboard the space station, the longest single spaceflight in history by an American.

The station tour is available to watch on the agency’s NASA+ streaming platform, NASA app, NASA Television, YouTube, and the agency’s website.

Continuously inhabited for more than 23 years, the space station is a scientific platform where crew members conduct experiments across multiple disciplines of research, including Earth and space science, biology, human physiology, physical sciences, and technology demonstrations that could not be performed on Earth.

The Payload Operations Integration Center at NASA’s Marshall Space Flight Center operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day.

The crew living aboard the station are the hands of thousands of researchers on the ground conducting more than 3,300 experiments in microgravity. During his record-breaking mission, Rubio spent many hours contributing to scientific activities aboard the orbiting laboratory, conducting everything from human health studies to plant research.

Rubio returned to Earth in September, having completed approximately 5,936 orbits of the Earth and a journey of more than 157 million miles during his first spaceflight, roughly the equivalent of 328 trips to the Moon and back.

NASA’s Dragonfly to Proceed with Final Mission Design Work

NASA’s Dragonfly mission has been authorized to proceed with work on final mission design and fabrication – known as Phase C – during FY (fiscal year) 2024. The agency is postponing formal confirmation of the mission (including its total cost and schedule) until mid-2024, following the release of the FY 2025 President’s Budget Request.

Earlier this year, Dragonfly – a mission to send a rotorcraft to explore Saturn’s moon Titan – passed all the success criteria of its Preliminary Design Review. The Dragonfly team conducted a re-plan of the mission based on expected funding available in FY 2024 and estimate a revised launch readiness date of July 2028. The agency will officially assess the mission’s launch readiness date in mid-2024 at the agency Program Management Council.

“The Dragonfly team has successfully overcome a number of technical and programmatic challenges in this daring endeavor to gather new science on Titan,” said Nicola Fox, associate administrator of NASA’s Science Mission Directorate at NASA Headquarters. “I am proud of this team and their ability to keep all aspects of the mission moving toward confirmation.”

Dragonfly takes a novel approach to planetary exploration, for the first time employing a rotorcraft-lander to travel between and sample diverse sites on Titan. Dragonfly’s goal is to characterize the habitability of the moon’s environment, investigate the progression of prebiotic chemistry in an environment where carbon-rich material and liquid water may have mixed for an extended period, and even search for chemical indications of whether water-based or hydrocarbon-based life once existed on Titan.

Dragonfly is being designed and built under the direction of the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, which manages the mission for NASA. The team includes key partners at NASA’s Goddard Space Flight Center; Lockheed Martin Space in Littleton, Colorado; Sikorsky, a Lockheed Martin company; NASA’s Ames Research Center; NASA’s Langley Research Center; Penn State University in State College, Pennsylvania; Malin Space Science Systems in San Diego, California; Honeybee Robotics in Pasadena, California; NASA’s Jet Propulsion Laboratory; CNES (Centre National d’Etudes Spatiales), the French space agency, in Paris, France; DLR (German Aerospace Center) in Cologne, Germany; and JAXA (Japan Aerospace Exploration Agency) in Tokyo, Japan.

Dragonfly is the fourth mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center for the Science Mission Directorate.

Webb Telescope: A Prominent Protostar in Perseus

A new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797, known as HH 797.

Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds. HH 797, which dominates the lower half of the image, is located close to the young open star cluster IC 348, which is located near the eastern edge of the Perseus dark cloud complex. The bright infrared objects in the upper portion of the image are thought to host two further protostars.

In the lower half of the image is a narrow, horizontal nebula that stretches from edge to edge. It is brightly coloured with more variety on its right side. In the upper half there is a glowing point with multi-coloured light radiating from it in all directions. A bright star with long diffraction spikes lies along the right edge, and a few smaller stars are spread around. The background is covered in a thin haze.

The bright infrared objects in the upper portion of the image are thought to host two further protostars. This image was captured with Webb’s Near-InfraRed Camera (NIRCam).

The image was captured with Webb’s NIRCam (Near-InfraRed Camera). Infrared imaging is powerful in studying newborn stars and their outflows, because the youngest stars are invariably still embedded within the gas and dust from which they are formed. The infrared emission of the star’s outflows penetrates the obscuring gas and dust, making Herbig-Haro objects ideal for observation with Webb’s sensitive infrared instruments. Molecules excited by the turbulent conditions, including molecular hydrogen and carbon monoxide, emit infrared light that Webb can collect to visualize the structure of the outflows. NIRCam is particularly good at observing the hot (thousands of degree Celsius) molecules that are excited as a result of shocks.

Using ground-based observations, researchers have previously found that for cold molecular gas associated with HH 797, most of the red-shifted gas (moving away from us) is found to the south (bottom right), while the blue-shifted gas (moving towards us) is to the north (bottom left). A gradient was also found across the outflow, such that at a given distance from the young central star, the velocity of the gas near the eastern edge of the jet is more red-shifted than that of the gas on the western edge. Astronomers in the past thought this was due to the outflow’s rotation. In this higher resolution Webb image, however, we can see that what was thought to be one outflow is in fact made up of two almost parallel outflows with their own separate series of shocks (which explains the velocity asymmetries). The source, located in the small dark region (bottom right of center), and already known from previous observations, is therefore not a single but a double star. Each star is producing its own dramatic outflow. Other outflows are also seen in this image, including one from the protostar in the top right of center along with its illuminated cavity walls.

HH 797 resides directly north of HH 211 (separated by approximately 30 arcseconds), which was the feature of a Webb image release in September 2023.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency. Several NASA centers contributed to the project, including NASA’s Marshall Space Flight Center.

      6 Min Read NASA Marshall Reflects on 65 Years of Ingenuity, Teamwork 
      NASA’s Marshall Space Flight Center in Huntsville, Alabama, is celebrating its 65-year legacy of ingenuity and service to the U.S. space program – and the expansion of its science, engineering, propulsion, and human spaceflight portfolio with each new decade since the NASA field center opened its doors on July 1, 1960.
      What many Americans likely call to mind are the “days of smoke and fire,” said Marshall Director Joseph Pelfrey, referring to the work conducted at Marshall to enable NASA’s launch of the first Mercury-Redstone rocket and the Saturn V which lifted Americans to the Moon, the inaugural space shuttle mission, and the shuttle flights that carried the Hubble Space Telescope, Chandra X-ray Observatory, and elements of the International Space Station to orbit. Most recently, he said they’re likely to recall the thunder of NASA’s SLS (Space Launch System), rising into the sky during Artemis I.
      NASA’s Space Launch System, carrying the Orion spacecraft, launches on the Artemis I flight test on Nov. 16, 2022. NASA’s Marshall Space Flight Center in Huntsville, Alabama, led development and oversees all work on the new flagship rocket, building on its storied history of propulsion and launch vehicle design dating back to the Redstone and Saturn rockets. The most powerful rocket ever built, SLS is the backbone of NASA’s Artemis program, set to carry explorers back to the Moon in 2026, help establish a permanent outpost there, and make possible new, crewed journeys to Mars in the years to come.NASA/Bill Ingalls Yet all the other days are equally meaningful, Pelfrey said, highlighting a steady stream of milestones reflecting the work of Marshall civil service employees, contractors, and industry partners through the years – as celebrated in a new “65 Years of Marshall” timeline.
      “The total sum of hours, contributed by tens of thousands of men and women across Marshall’s history, is incalculable,” Pelfrey said. “Together they’ve blended legacy with innovation – advancing space exploration and scientific discovery through collaboration, engineering excellence, and technical solutions. They’ve invented and refined technologies that make it possible to safely live and work in space, to explore other worlds, and to help safeguard our own.
      The total sum of hours, contributed by tens of thousands of men and women across Marshall’s history, is incalculable.
      Joseph Pelfrey
      Marshall Space Flight Center Director
      “Days of smoke and fire may be the most visible signs, but it’s the months and years of preparation and the weeks of post-launch scientific discovery that mark the true dedication, sacrifice, and monumental achievements of this team.”
      Reflecting on Marshall history
      Marshall’s primary task in the 1960s was the development and testing of the rockets that carried the first American astronaut to space, and the much larger and more technically complex Saturn rocket series, culminating in the mighty Saturn V, which carried the first human explorers to the Moon’s surface in 1969.
      “Test, retest, and then fly – that’s what we did here at the start,” said retired engineer Harry Craft, who was part of the original U.S. Army rocket development team that moved from Fort Bliss, Texas, to Huntsville to begin NASA’s work at Marshall. “And we did it all without benefit of computers, working out the math with slide rules and pads of paper.”
      The 138-foot-long first stage of the Saturn V rocket is lowered to the ground following a successful static test firing in fall 1966 at the S-1C test stand at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The Saturn V, developed and managed at Marshall, was a multi-stage, multi-engine launch vehicle that stood taller than the Statue of Liberty and lofted the first Americans to the Moon. Its success helped position Marshall as an aerospace leader in propulsion, space systems, and launch vehicle development.NASA “Those were exciting times,” retired test engineer Parker Counts agreed. He joined Marshall in 1963 to conduct testing of the fully assembled and integrated Saturn first stages. It wasn’t uncommon for work weeks to last 10 hours a day, plus weekend shifts when deadlines were looming. 
      Counts said Dr. Wernher von Braun, Marshall’s first director, insisted staff in the design and testing organizations be matched with an equal number of engineers in Marshall’s Quality and Reliability Assurance Laboratory. 
      “That checks-and-balances engineering approach led to mission success for all 32 of the Saturn family of rockets,” said Counts, who went on to support numerous other propulsion programs before retiring from NASA in 2003.
      “We worked with the best minds and best equipment available, pushing the technology every day to deliver the greatest engineering achievement of the 20th century,” said instrumentation and electronics test engineer Willie Weaver, who worked at Marshall from 1960 to 1988 – and remains a tour guide at its visitor center, the U.S. Space & Rocket Center.

      Former Marshall Space Flight Center Employee
      The 1970s at Marshall were a period of transition and expanded scientific study, as NASA ended the Apollo Program and launched the next phase of space exploration. Marshall provided critical work on the first U.S. space station, Skylab, and led propulsion element development and testing for NASA’s Space Shuttle Program.
      Marshall retiree Jim Odom, a founding engineer who got his start launching NASA satellites in the run-up to Apollo, managed the Space Shuttle External Tank project. The role called for weekly trips to NASA’s Michoud Assembly Facility in New Orleans, which has been managed by Marshall since NASA acquired the government facility in 1961. The shuttle external tanks were manufactured in the same bays there where NASA and its contractors built the Saturn rockets. 
      This photograph shows the liquid hydrogen tank and liquid oxygen tank for the Space Shuttle external tank (ET) being assembled in the weld assembly area of the Michoud Assembly Facility (MAF). The ET provides liquid hydrogen and liquid oxygen to the Shuttle’s three main engines during the first eight 8.5 minutes of flight. At 154-feet long and more than 27-feet in diameter, the ET is the largest component of the Space Shuttle, the structural backbone of the entire Shuttle system, and the only part of the vehicle that is not reusable. The ET is manufactured at the Michoud Assembly Facility near New Orleans, Louisiana, by the Martin Marietta Corporation under management of the Marshall Space Flight Center.NASA “We didn’t have cellphones or telecon capabilities yet,” Odom recalled. “I probably spent more time with the pilot of the twin-engine plane in those days than I did with my wife.”
      Marshall’s shuttle propulsion leadership led to the successful STS-1 mission in 1981, launching an era of orbital science exemplified by NASA’s Spacelab program. 
      “Spacelab demonstrated that NASA could continue to achieve things no one had ever done before,” said Craft, who served as mission manager for Spacelab 1 in 1983 – a highlight of his 40-year NASA career. “That combination of science, engineering, and global partnership helped shape our goals in space ever since.” 
      Engineers in the X-ray Calibration Facility at NASA’s Marshall Space Flight Center in Huntsville, Alabama, work to integrate elements of the Chandra X-ray Observatory in this March 1997 photo. Chandra was lifted to orbit by space shuttle Columbia on July 23, 1999, the culmination of two decades of telescope optics, mirror, and spacecraft development and testing at Marshall. In the quarter century since, Chandra has delivered nearly 25,000 detailed observations of neutron stars, supernova remnants, black holes, and other high-energy objects, some as far as 13 billion light-years distant. Marshall continues to manage the program for NASA. NASA Bookended by the successful Hubble and Chandra launches, the 1990s also saw Marshall deliver the first U.S. module for the International Space Station, signaling a transformative new era of human spaceflight.
      Odom, who retired in 1989 as associate administrator for the space station at NASA Headquarters, reflects on his three-decade agency career with pride. 
      “It was a great experience, start to finish, working with the teams in Huntsville and New Orleans and our partners nationwide and around the globe, meeting each new challenge, solving the practical, day-to-day engineering and technology problems we only studied about in college,” he said.

Marshall played a key role in the development, testing, and delivery of the truss and other critical space station modules and structural elements, as well as the station’s air and water recycling systems and science payload hardware. Marshall’s Payload Operations Integration Center also continues to lead round-the-clock space station science. NASA That focus on human spaceflight solutions continued into the 21st century. Marshall delivered additional space station elements and science hardware, refined its air and water recycling systems, and led round-the-clock science from the Payload Operations Integration Center. Marshall scientists also managed the Gravity Probe Band Hinode missions and launched NASA’s SERVIR geospatial observation system. Once primary space stationconstruction – and the 40-year shuttle program – concluded in the 2010s, Marshall took on oversight of NASA’s Space Launch System, led James Webb Space Telescope mirror testing, and delivered the orbiting Imaging X-ray Polarimetry Explorer.
      As the 2020s continue, Marshall meets each new challenge with enthusiasm and expertise, preparing for the highly anticipated Artemis II crewed launch and a host of new science and discovery missions – and buoyed by strong industry partners and by the Huntsville community, which takes pride in being home to “Rocket City USA.”
      “Humanity is on an upward, outward trajectory,” Pelfrey said. “And day after day, year after year, Marshall is setting the course to explore beyond tomorrow’s horizon.”

Webb, which launched Dec. 25, 2021, is the  largest, most powerful, and most complex space science telescope ever built. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.
      John Mather, senior project scientist on Webb and a senior astrophysicist at Goddard, nominated Gardner for the fellowship. In his nomination, Mather wrote:
      “Jonathan Gardner is a quiet superstar, well known to the Webb community. As deputy senior project scientist for Webb, Gardner represents the senior project scientist in all aspects of the mission, with responsibility for ensuring Webb’s scientific performance. Gardner is a tireless advocate for the scientific vision and its accurate implementation. He is the main spokesperson for Webb science throughout NASA and in the wider astronomy community. He is the person most responsible for keeping the science teams working well together and for communicating with other astronomers.”
      Gardner began working on Webb as a member of the Ad-Hoc Science Working Group in the late 1990s, joining the project as the deputy senior project scientist in 2002. 
      Beginning in 2002, Gardner organized all the meetings and communications of the Science Working Group, which included people from the U.S., Europe, and Canada, including instrument teams and other partners. He recruited Goddard scientists for the mission’s Project Science Team, and ensured a scientist was assigned to every engineering topic. Gardner also wrote and published the scientific requirements in a dedicated issue of Space Science Reviews. He set up the Science Requirements Analysis Board to review any potential threats to the scientific goals of the mission and worked with engineering teams to avoid any failures. He represented scientific interests throughout the engineering project and throughout NASA, by ensuring regular communication between scientists, managers, and engineers.   
      The 2023 AAS Fellows are recognized for enhancing and sharing humanity’s scientific understanding of the universe through personal achievement and extraordinary service to the astronomical sciences and to the AAS.
      AAS, established in 1899, is a major international organization of professional astronomers, astronomy educators, and amateur astronomers. Its membership of approximately 8,000 also includes physicists, geologists, engineers, and others whose interests lie within the broad spectrum of subjects now comprising the astronomical sciences. The mission of the AAS is to enhance and share humanity’s scientific understanding of the universe as a diverse and inclusive astronomical community, which it achieves through publishing, meetings, science advocacy, education and outreach, and training and professional development.

      In 2023, NASA Langley’s workforce brought imagination to reality with innovative technological development and a continued commitment to tackling some of the tough challenges that both NASA and the nation face.

      NASA At NASA, we aspire to know more, dig deeper, climb higher and along the way we are asking, ‘What if?’,” said NASA Langley Center Director Clayton P. Turner in an introductory message to Langley’s 2023 Annual Report. “Our inquisitive nature propels us on our mission to reach for new heights and reveal the unknown for the benefit of humankind.”

      All year, the Langley workforce pondered and planned for a future alongside self-flying drones, aircraft with reduced emissions, air travel that benefits from greater fuel efficiency and space exploration assisted by inflatable heat shields that could give us the ability to carry greater payloads than ever before.

      “We invite you to explore all that NASA’s Langley Research Center has to offer — our amazing people, unique capabilities, and legacy of success,” Turner said in his introduction.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      From left, NASA astronauts, Tracy C. Dyson, Mike Barratt, Matthew Dominick, and Jeanette Epps, who served as part of Expedition 71, will discuss their recent missions to the International Space Station during a visit to Marshall Space Flight Center on Jan. 29. NASA NASA will host four astronauts at 9 a.m. CDT Wednesday, Jan. 29, for a media opportunity at the agency’s Marshall Space Flight Center in Huntsville, Alabama.
      NASA astronauts Matt Dominick, Mike Barratt, Jeanette Epps, and Tracy C. Dyson served as part of Expedition 71 and will discuss their recent missions to the International Space Station.
      Dominick, Barratt, and Epps launched aboard NASA’s SpaceX Crew-8 mission in March 2024 and returned to Earth in October 2024 after spending nearly eight months aboard the orbiting complex. Dyson launched aboard a Roscosmos Soyuz spacecraft also in March 2024 and returned in September 2024 after completing a six-month research mission aboard the space station.
      Media are invited to attend the event and visit with the astronauts as they discuss their science missions aboard the microgravity laboratory and other mission highlights. Media interested in participating must confirm their attendance by 12 p.m., Monday, Jan. 27, to both Lance D. Davis – lance.d.davis@nasa.gov – and Joel Wallace – joel.w.wallace@nasa.gov –  in Marshall’s Office of Communications. 
      Media must arrive by 8 a.m., Wednesday, to the Redstone Arsenal Joint Visitor Control Center Gate 9 parking lot, located at the Interstate 565 interchange on Research Park Boulevard. The event will take place in the NASA Marshall Activities Building 4316. Vehicles are subject to a security search at the gate, so please allow extra time. All members of the media and drivers will need photo identification. Drivers will need proof of insurance if requested.
      The Expedition 71 crew conducted hundreds of technology demonstrations and science experiments, including the bioprinting of human tissues. These higher-quality tissues printed in microgravity could help advance the production of organs and tissues for transplant and improve 3D printing of foods and medicines on future long-duration space missions. The crew also looked at  neurological organoids, created with stem cells from patients to study neuroinflammation, a common feature of neurodegenerative conditions such as Parkinson’s disease. The organoids provided a platform to study these diseases and their treatments and could help address how extended spaceflight affects the brain.
      As part of Crew-8, Dominick served as commander, Barratt served as pilot, and Epps served as a mission specialist. Dyson launched aboard a Soyuz space as part of an international crew and served as a flight engineer on a six-month research mission. The expedition to the space station was the first spaceflight for Dominick, third for Barratt, first for Epps, and third for Dyson.
      The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including missions to the Moon under Artemis and, ultimately, human
