NASA Langley’s “Stars, Stripes, and Supernovas – Symphony Under the Stars” event brought employees, families, and community members together for an evening filled with music, connection, and celebration.
Organizers planned the event, which took place July 16, to mark the 250th anniversary of the founding of the United States of America.
The evening featured a dynamic mix of performances from an orchestra that included NASA Langley employees and members of the Williamsburg Youth Orchestra, as well as smaller group performances from employees and special guest artist Karl Werne.
“It’s fun to bring people together, to share their diverse talents in order to create something that’s meaningful – and in this case something that was very beautiful too,” said Jennifer Kibler, deputy director of the Research Directorate at NASA Langley.
The orchestra played a selection of patriotic favorites and space-inspired pieces that highlighted the creativity and talent within the community. “America the Beautiful,” “God Bless America,” and “Jupiter, the Bringer of Jollity” from Gustav Holst’s orchestral suite “The Planets” were among the songs they performed.
The event, which also took place just one day before NASA Langley’s 109th birthday, served as a reminder of the spirit that defines the center—scientists, engineers, communicators, and staff coming together to celebrate not only NASA’s mission, but the people who make that mission possible.
“This was a big team effort,” said Nicole Oman, administrative management specialist with the Research Directorate. “It wouldn’t have been a success without the contributions of every single person.”
Human exploration of Mars will expose crews to a persistent, fine particulate environment whose physicochemical properties and health implications remain only partly understood. Because no samples of authentic Martian airborne dust have been returned to Earth, NASA must rely on lunar dust toxicology, Martian regolith simulants, and extensive rover/lander geochemical and mineralogical datasets to develop an initial, risk‑informed Permissible Exposure Limit (PEL). The Johnson Space Center (JSC) Lunar and Martian Dust Risk Custodian, the JSC Toxicology group, and the OCHMO Standards team worked together to draft a preliminary standard for incorporation into NASA-STD-3001 NASA Spaceflight Human-System Standard, Volume 2: Human Factors, Habitability, and Environmental Health.
The Martian Dust Limit Working Group was assembled to review this draft standard and associated evidence. Across two working sessions in February 2026, panel members reviewed mission architecture drivers, the current scientific understanding of Martian dust composition, and the toxicological evidence base supporting the establishment of a Mars dust PEL. Discussions emphasized the critical interplay between dust standards and Mars mission design elements including Extravehicular Activity (EVA) cadence, dust ingress characteristics, and the performance of habitat environmental control systems; these features highlight the need for a limit that is conservative, verifiable, and adaptable as the Mars architecture evolves. Panel members for the Working Group were David Damby, Claire Horwell, Brian Hynek, Shaunna Morrison, and Joyce Tsuji; NASA presenters were Katie Borremans, Elizabeth Rampe, and Torin McCoy; the OCHMO organizers/moderators were Douglas Ebert, David Francisco, and Kim Lowe. The Working Group meetings were also attended by members of Space Medicine and Operations group and JSC Toxicology.
Evaluate NASA’s proposed derivation of this initial standard
The panel concluded that NASA’s approach to deriving a 30‑day continuous PEL of 0.1 mg/m³ is reasonable and appropriately conservative for early short‑stay missions. This value originates from the established lunar 30‑day PEL (0.4 mg/m³), reduced by a 3x database uncertainty factor to account for knowledge gaps in Martian dust toxicity, higher iron content, amorphous constituents, and differences between simulants and actual dust. Members supported this framework, noting that a continuous limit applied using measured time‑weighted averages is more practical than making assumptions tied to fixed dust clearance rates given the diversity of spacecraft designs. They also acknowledged that near‑term exposures will be peak‑driven (e.g., post‑EVA suit ingress) and therefore recommended that the standard explicitly address the need to manage short‑duration spikes.
Identify chemical constituents requiring further scrutiny
The panel affirmed that overall dust mass remains the primary near‑term engineering concern, but several chemical constituents warrant attention. Chromium 6+, manganese, and perchlorate were all considered low‑risk in the context of inhaled Martian dust, provided the overall dust PEL is applied (see below). However, perchlorate was recommended for broader agency‑level exposure management across multiple intake routes (e.g., ingestion due to in situ crop growth). Iron was discussed in detail due to its high abundance in Martian regolith and its potential to generate Reactive Oxygen Species (ROS), though current toxicology shows no clear link between iron‑driven ROS and pulmonary harm; still, knowledge gaps led the panel to prioritize iron for further study and potential Spacecraft Maximum Allowable Concentration (SMAC) development. Arsenic was judged unlikely to pose meaningful risk at present.
Weigh the merits of an overall dust limit versus separate SMACs
Chemical constituents embedded within Martian dust were evaluated with respect to whether independent SMACs are warranted. Based on rover observations indicating predominantly trivalent chromium, low airborne perchlorate, and manganese concentrations well below conservative SMAC thresholds at the proposed PEL, the group agreed that the overall dust limit is likely sufficiently protective for expected 30‑day missions. However, panel members advised that SMACs be maintained for select constituents such as perchlorate and manganese for mission‑planning crosschecks. From the requirement perspective, an overall Martian dust PEL approach was favored for practicality and clarity, with constituent-specific SMACs retained or developed only where they add tangible operational value.
Refine the standard’s technical language for operational use
The working group also refined the standard language to ensure clarity and consistency in implementation. Members recommended that the limit apply to a specified time‑weighted average measurement period but also making it explicit that the requirement is for protection during continuous exposure. They encouraged incorporation of peak‑exposure management within the rationale, and highlighted uncertainties related to iron content, nanophase iron, and oxidative potential so that future revisions can incorporate emerging scientific insight.
The new requirement established for NASA-STD-3001 is as follows:
[V2 6253] The system shall limit the concentrations of Martian dust particles less than 10 μm in size in the habitable atmosphere below a 24-hour time-weighted average of 0.1 mg/m3 during exposure scenarios lasting up to 30 days in duration.
Taken together, the working group’s deliberations reinforce that an initial Martian dust standard must balance conservatism with operational feasibility while accommodating architectural and scientific uncertainty. The proposed requirement provides a defensible, evidence‑informed foundation for design, verification, and risk communication. As additional Martian data and toxicological research become available, this standard should be periodically revisited to ensure continued protection of crew health during human exploration of Mars.

Fifty years ago, NASA’s Viking 1 and 2 landers made the first successful landings on Mars, opening a new era in planetary exploration. Behind that achievement was a team at NASA’s Langley Research Center in Hampton, Virginia, whose steady leadership and technical expertise helped turn an ambitious idea into a mission that reshaped how we explore other worlds.
NASA selected Langley in 1968 to lead the massive Viking project, the first U.S. mission designed to land safely on Mars and search for signs of life. Project Manager James S. Martin Jr. set the tone from the start. He wanted clear priorities, tough engineering reviews, and the discipline to test every system until the team was confident it would perform on Mars.
Langley engineers faced a challenge unlike anything attempted before: slowing a spacecraft plunging into the Martian atmosphere at more than 10,000 miles per hour. So they leaned into their expertise in atmospheric entry aerodynamics, heat shielding, and parachute technology. Their work produced the protective aeroshell and heat shield, as well as the supersonic parachute. These systems didn’t come from theory alone — they were shaped by years of wind‑tunnel tests, analysis, and problem‑solving. Langley still excels at entry, descent, and landing systems today.
Langley also helped create a new approach to finding safe landing sites. Teams combined images from Viking’s orbiters with radar data from Earth‑based observatories to identify regions that balanced scientific value with engineering safety — a method now standard for Mars missions.
Viking also changed how mission teams operated. Engineers and scientists adopted the sol — a Martian day slightly longer than 24 hours — to keep daily work aligned with local time on Mars, a practice still used for surface missions.
Viking grew out of a pivotal program shift. The earlier Voyager Mars lander concept was canceled because it was too costly and risky, relying on two large landers stacked on a single Saturn V rocket. Langley helped chart a more realistic path forward, pairing each lander with its own orbiter and using Titan IIIE‑Centaur rockets instead. The new design preserved scientific ambition while making the mission achievable.
Viking provided an early model for how NASA could explore the solar system: scout with orbiters, certify landing sites with real data, and land only with systems tested well beyond their limits. That “planetary playbook,” shaped heavily by Langley, provided a guide for future Mars missions like Curiosity and Perseverance.
The two landers returned thousands of images and groundbreaking data, revealing Mars as a world with weather, geologic history, and complexity that scientists are still studying today. And while no human has ever set foot on the Martian surface, Viking proved that reaching another planet — and working on it — was within reach.
As the 50th anniversary of those landings arrives, Langley’s influence is unmistakable. The center continues to advance new entry, descent, and landing technologies, and explore concepts that will support future human explorers. The same spirit that guided Viking still drives the work happening in Hampton today — steady, curious, and always looking toward the next horizon.

The Republic of Mauritius has officially joined the global coalition committed to responsible space exploration, becoming the newest signatory and seventh African country to join the Artemis Accords. NASA’s Deputy Administrator Matt Anderson contributed video remarks for a signing ceremony on Friday, in the island nation’s city of Ébène.
“We are honored to welcome Mauritius to the Artemis Accords community and look forward to working together in the years ahead,” said Anderson. “Together, we are creating the foundation for future exploration while ensuring that space remains peaceful, accessible, and beneficial for all. America will return to the Moon and ignite the Golden Age of exploration and discovery. That work requires capable partners and a shared commitment to responsible exploration.”
Mauritius’ Permanent Secretary at the Ministry of Tertiary Education, Science and Research Navindsing Jugmohunsing signed the Artemis Accords on behalf of the country. U.S. Deputy Assistant Secretary of State for African Affairs Sarah Troutman and U.S. Chargé d’Affaires to Mauritius Craig Halbmaier were present to witness the signing.
“The accession of Mauritius to the Artemis Accords marks a defining chapter in our New Space journey,” said Jugmohunsing. “As a Small Island Developing State in the Indian Ocean, we are committed to ensuring that space serves humanity by protecting our oceans and coastlines and amplifying the voices of nations like ours. Mauritius stands ready to help shape the future of space governance while unlocking new opportunities for innovation and partnership.”
NASA first engaged with Mauritius through its early global mapping efforts, owing to the nation’s strategic location. Between 1965 and 1980, NASA used several satellite missions to collect global measurements of Earth’s size and shape. As part of that work, NASA sent teams to Mauritius and other international tracking stations that supported satellite photography for geodetic analysis. Their observations strengthened the navigation technologies used from Apollo to Artemis and helped lay the foundation for the partnership reaffirmed today by the Artemis Accords.
In 2020, NASA and the Department of State joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. They introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars, and beyond, committing nations to:
Five years later, President Donald J. Trump’s National Space Policy directed NASA to establish a sustained lunar outpost. With this Moon Base, NASA is putting the principles of the Artemis Accords into practice, inviting every signatory including now Mauritius to take part in the endeavor.
More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.

Moon Mascot: NASA Artemis II ZGI Design Challenge
Last year, the Moon mascot design contest received thousands of submissions from more than fifty countries for the Artemis II mission’s zero‑gravity indicator. This plush item serves a special purpose — it begins to float once the astronauts reach space, signaling the onset of zero gravity. It also provides a comforting reminder of Earth when the crew is far from home.
Ultimately, the Artemis II astronauts selected “Rise”—inspired by the iconic Earthrise photograph captured during the Apollo 8 mission and designed by Lucas Ye of Mountain View, California—as the zero‑gravity indicator that will accompany them around the Moon. “Rise” also features a small pouch that will carry an SD card containing all 5.6 million names submitted through the Send Your Name with Artemis campaign.
Send Your Name with Artemis II
NASA invited the public to join the agency’s Artemis II test flight as four astronauts ventured around the Moon and back to test the systems and hardware needed for deep space exploration. As part of the agency’s “Send Your Name with Artemis II” effort, anyone could claim their spot by signing up before Jan. 21, 2026. Participants launched their names aboard the Orion spacecraft and SLS (Space Launch System) rocket alongside NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen.
The April 1, 2026, Google Doodle celebrated the launch of Artemis II, the NASA mission that sent astronauts around the Moon and back for the first time in more than 50 years. During the approximately 10‑day voyage, the crew tested the spacecraft’s systems while traveling farther into deep space than any human had gone since the Apollo program. This critical test flight brought us one step closer to a long‑term return to the Moon and future missions to Mars.

The Artemis II mission launched April 1, 2026, on NASA’s SLS (Space Launch System) rocket from Kennedy Space Center in Florida. During the nearly 10‑day test flight, the crew achieved the mission’s primary objectives, including testing its life support systems; manually piloting the Orion spacecraft; performing maneuvers to propel Orion to the Moon and adjust its course; conducting a lunar flyby with unprecedented views of the Moon’s far side; and completing a safe re-entry and recovery. The astronauts also set a record for the farthest distance traveled by humans away from Earth.
As part of a Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly challenging missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and lay the groundwork for sending the first astronauts – American astronauts – to Mars.
From June 3 to 13, aircraft at Ellington Field in Houston gave students a firsthand look at how scientists study Earth from the air.
Through NASA’s Student Airborne Research Program, or SARP, students learned how airborne field campaigns collect data used in atmospheric science, ecology, air quality research, and climate modeling.
This year’s activity took place alongside an air quality campaign led by NOAA (National Oceanic and Atmospheric Administration), giving students a chance to see how federal agencies work together to study Earth’s atmosphere.
“Every SARP flight is more than a mission; it’s a classroom in the sky, where students learn how science is planned, executed, and transformed into discovery,” said NASA’s Ames Research Center Earth Science Project Specialist Vidal Salazar.
The NOAA effort allowed NASA to build on active atmospheric research already underway in Texas. By integrating additional aircraft into the campaign, students gained access to a real-world research environment and saw how scientists collect data from the air.
Students attend daily lectures, take coding classes, work with instrument teams, and use campaign data and NASA’s extensive archive to design, implement, and present independent research projects.
“SARP is full of passionate individuals who work together to inspire the next generation of Earth scientists,” said SARP Project Manager Joelle Hopkins.
Students work with NASA subject matter experts throughout the program, giving them exposure to a range of career paths in airborne science.
“It is great seeing different students with very diverse backgrounds exploring the next step in their academic journey,” said NASA’s Goddard Space Flight Center Lead Forecaster Joe Finlon.
The operations involved the agency’s Gulfstream V (N95NA); Gulfstream C-20A (N802NA); and Gulfstream III (N520NA), as well as NOAA’s WP-3D Orion (N43RF), and a King Air B200 aircraft (N46L), owned by Dynamic Aviation and contracted by NASA.
The WP-3D Orion conducted maneuvers as low as 1,000 feet above ground level. Owned and operated by NOAA, the aircraft is used as a hurricane hunter and has supported several airborne science missions for NASA.
NASA aircraft also carried instruments that support atmospheric science and ecology research. One instrument – the Airborne Visible/Infrared Imaging Spectrometer, or AVIRIS – was used to characterize Earth’s surface and atmosphere. Additional atmosphere and air quality measurements were collected by instruments including the High Spectral Resolution Lidar 2, GeoCAPE Airborne Spectrometer, Uninhabited Aerial Vehicle Synthetic Aperture Radar, and Aerosol Wind Profiler.
Low-altitude flights are important for this type of work because aircraft must fly close enough to Earth’s surface for instruments to collect data at the needed resolution.
For NOAA’s campaign, aircraft measurements can help researchers study air quality conditions and feed data into numerical models. Since similar measurements are collected over time, researchers can compare conditions from year to year and better understand changes in pollution and atmospheric chemistry.

For more than 100 years, wind tunnels at NASA’s Langley Research Center in Hampton, Virginia, have helped shape the future of flight.
Now, two of NASA’s longest-serving facilities — the 12-Foot Low-Speed Tunnel and the 20-Foot Vertical Spin Tunnel — will pass the torch to the Flight Dynamics Research Facility (FDRF), the first major NASA wind tunnel built in more than 40 years.
“The FDRF has a combination of features found in no other single facility in the world,” said Mike Fremaux, retired chief engineer for the Intelligent Flight Systems division at NASA Langley. “It’s a high-performance vertical wind tunnel with a large test section capable of conducting all manner of tests to assess the dynamics of flight vehicles.”
When the FDRF opens later this year, it will provide enhanced versions of the capabilities offered by the two legacy facilities. The FDRF’s test section will allow researchers to drop models into a rising vertical airflow. This will offer researchers the ability to conduct spin tests of aircraft and free-flight tests of vehicles designed to re-enter Earth’s atmosphere from space.
The FDRF will play an integral role in conducting research that supports NASA’s aeronautics, science, and space exploration missions. Like many NASA facilities, the FDRF’s story is rooted in a history of innovation.
When the 12-Foot Low-Speed Tunnel began operations in 1939, aviation looked very different than it does today.
It was built for NASA’s predecessor agency, the National Advisory Committee for Aeronautics (NACA) to study the controllability of airplanes using free flight. Aircraft models flew unsupported in the wind it generated, instead of being mounted to supports. Multiple operators used rudimentary remote controls to operate the models in the tunnel.
The facility that housed the tunnel boasted a unique design: a 60-foot diameter sphere. The configuration allowed the tunnel to move and adapt to the flight paths of free flying models. “Pilots” could use hydraulic actuators, pivoting the tunnel’s test section to match the models’ movements. The spherical design made it easy for air from the facility’s fan to recirculate through the tunnel, regardless of the pitch angle of the test section.
In 1958, NASA moved the free-flight tests to another Langley tunnel. The agency deactivated the 12-Foot’s hydraulic actuators, fixing its test section into a horizontal position, and began using it for more conventional testing, looking at how aerodynamic force affected the stability and control of strut-mounted models.
The 12-Foot supported major projects throughout its 86 years of service, from the transition from bi-planes to monoplanes between two world wars, through the development of supersonic aircraft. Revolutionary designs saw testing in the 12-Foot, from the forward-swept-wing X-29 and the X-31 Enhanced Fighter Maneuverability Demonstrator, to the more recent X-59 quiet supersonic research aircraft, and the aeroshell for NASA’s Dragonfly, a unique rotorcraft designed to explore Titan, Saturn’s largest moon.
The 12-Foot closed in 2025, but its legacy will be both felt and seen at the FDRF. Six wooden fan blades and the central metal fan hub from the 12-Foot are on display inside the FDRF’s control room.
While the 12-Foot tested new ideas for aircraft and components, the 20-Foot Vertical Spin Tunnel played a critical role in aviation safety.
Opened in 1941, the Vertical Spin Tunnel was designed to study aircraft stall and spin characteristics. Its aim was to prevent deadly accidents in which an aircraft enters an uncontrolled spin. The vertical design allowed models to fall into the rising airflow, simulating how aircraft behave during a spin. Researchers hand-launched models into the tunnel’s vertically rising airstream to evaluate those characteristics.
The tunnel quickly became one of the most important spin-testing facilities in the world. Research supported commercial aviation, parachute design systems, NASA space missions, and the development of nearly every U.S. military aircraft designed since World War II.
Models from many of those tests will be on display in the FDRF’s lobby, a testament to the Vertical Spin Tunnel’s rich history.
“It is great to showcase the legacy of work that started in the NACA days and will continue going forward for decades to come,” Fremaux said.
The FDRF will continue NASA’s commitment to world-class facilities and the unique expertise of the agency’s workforce.
“That’s what kept those other facilities going,” Fremaux said. “Not just the buildings, the fans, and the motors, but also the expertise associated with those facilities. You can’t have one without the other.”
The FDRF will build not only on the history of the 12-Foot tunnel and the Vertical Spin Tunnel, but on their equipment, including many of their major test rigs, instrumentation, and data systems, were repurposed for use in the FDRF, reducing costs and development time.
As NASA returns astronauts to the Moon through the Artemis program, the FDRF will play a vital role in testing the technologies for entry, descent, and landing that will ensure a safe return to Earth. Research within the FDRF also will support science missions to planets and moons with atmospheres, such as Venus and Saturn’s moon, Titan. The 25,000-square-foot facility will play a major role in experimental research for NASA’s development of X-planes, autonomous flight vehicles, and drones.
“For me, seeing FDRF come alive and being prepared to begin supporting important agency missions, after 30 years of working on the concept behind the scenes with formal and informal teams of motivated, innovative coworkers, is the most rewarding capstone I could have in my career,” Fremaux said.
Just as the 12-Foot Low-Speed Tunnel and the 20-Foot Vertical Spin Tunnel supported decades of aerospace innovation, the FDRF is ready to shape the future of flight.
