NASA Pushes New Wing Design to Find Structural Limits

NASA researchers recently put a new wing design, appearing long and thin with a lightweight structural design, through a series of grueling tests to find its structural limits. What they found left them encouraged about the wing’s potential, even when they pushed it past its intended limits.

The 15-foot Structural Wing Experiment Evaluating Truss-bracing (SWEET-15) test article is part of NASA’s research to develop future ultra-efficient aircraft. The design incorporates a long wing supported by an aerodynamic strut, based on NASA’s earlier Transonic Truss‑Braced Wing concept.

The research team is working to understand whether SWEET-15’s design and its new lightweight structural designs could help commercial airliners save fuel. But first, they need to understand how it behaves under the kinds of force wings experience in flight.

The SWEET-15 design originated with combining five different advanced composite manufacturing and assembly technologies that enabled the novel structural design. The 15-foot-long test article was then designed and fabricated at NASA’s Langley Research Center in Hampton, Virginia, before traveling to NASA’s Armstrong Flight Research Center in Edwards, California, for testing.

Over several months, NASA engineers intentionally bent the test wing in the Flight Loads Laboratory at NASA Armstrong. Numerous strain and load sensors, including fiber-optic strain sensors, were placed throughout the structure to track how the wing responded as forces increased.

The data from the sensors confirmed the predictions made by NASA’s computer models. According to initial findings, the wing withstood the anticipated in-flight forces without issue. The results provided the team with confidence in the new manufacturing approaches and methods for connecting wing parts used in SWEET-15, which could support future efficient aircraft designs. The manufacturing approach, developed at NASA Langley used the Integrated Structural Assembly of Advanced Composites robot, aims to produce lighter and stronger composite structures for aerospace vehicles.

The test concluded with a deliberate test-to-failure, where engineers increased loads beyond the wing’s design limits to determine how and where it would fail. The structure ultimately failed at roughly 127% of its design limit load, with visible damage appearing near the back edge of the wing and in the upper wing cover. This element of testing provided valuable insight into how the joints connecting the wing to its main strut and a secondary one, called a jury strut, behave under forces beyond the expected flight envelope.

This marks the first time a representative composite truss-braced wing configuration has undergone this type of structural evaluation.  It was made possible only through NASA collaboration across centers and projects, with researchers utilizing agency resources such as the Fiber Optic Sensing System developed to gather data on both aircraft and spacecraft.

To prepare for the testing, engineers at NASA Langley designed, analyzed, and manufactured the wing and completed safety preparations and lab setup.

Researchers will now analyze the data collected during testing to inform future airframe designs and support NASA’s ongoing efforts to develop more efficient aviation technologies.

The work is being conducted through NASA’s Subsonic Flight Demonstrator project in the agency’s Research Technology Mission Directorate. The successful testing of multiple innovative components marks a milestone in NASA’s aeronautics research.

The Growing Crescent of Mars as NASA’s Psyche Mission Approaches

PNG (3.48 MB)

Description

This composite of images taken by NASA’s Psyche mission shows the crescent of Mars grow as the spacecraft approached the planet for a gravity assist from May 2 to May 15, 2026. The series begins with the smallest crescent at the center of the of the image as Mars is farthest from the spacecraft, and progressively grows as the spacecraft gets closer. After these views were captured by the spacecraft’s multispectral imager instrument, Mars began to overfill the field of view as Psyche made close approach with the planet and captured a series of high-resolution images of the surface.

Because Psyche approached Mars from a high phase angle, the planet appeared as a thin crescent in the days running up to the close approach, lit by sunlight reflecting off its surface. Using these views of the approach, close approach, and departure from Mars, the Psyche team compiled a stunning time-lapse of its entire Mars encounter.

In April 2026, NASA’s Office of the Chief Health and Medical Officer (OCHMO) initiated a working group to review updated VTE case information, additional data gathered revealing altered blood flow status within a cohort of astronauts, and discuss progress of research and clinical activities intended to mitigate the risk of VTE during spaceflight with new evidence-based clinical practice recommendations.

Recommendations

The following is a summary of the working group’s recommendations:

• The working group’s conclusions emphasized that stasis in the left internal jugular vein (IJV) is consistently viewed as a dominant risk factor for VTE in microgravity, though there is active debate regarding the relative contributions of slow qualitative flow, endothelial factors and/or retrograde flow.
• Limitations of current in-flight ultrasound capabilities to accurately measure stasis/slow flow was cited as a concern, especially if using only stasis as a factor for indicating the need for prophylaxis.
• Additional review of assessing stasis with ultrasound in-flight was recommended.
• After reviewing the risk factors, additional discussions following the working group led to the majority of the panel agreeing that stasis and retrograde flow warranted use of prophylaxis.
• The working group also recommended assessing all other risk factors other than stasis to also determine when prophylaxis is warranted.
• Based on a literature review and summary of the panel contributions, a VTE Risk Score for Astronauts Algorithm was developed, which includes providing anticoagulation prophylaxis for stasis alone, or a combination of other thrombosis risk factors that are weighted by terrestrial literature.

Risk of Venous Thromboembolism During Spaceflight

NASA initially formed a working group in October 2024 after diagnosing venous thromboembolisms (VTEs) in astronauts during ISS missions. Experts reviewed case data, updated Clinical Practice Guidelines, and examined possible causes.

NASA’s Psyche Mission Images Details of Martian Surface During Flyby

PNG (4.47 MB)

Description

Captured by the multispectral imager instrument on NASA’s Psyche mission, this is an enhanced-color mosaic created from four individual images acquired on May 15, 2026, during the spacecraft’s flyby of Mars. 

Psyche was traveling from right to left (northeast to southwest on Mars) during the six minutes that it took to acquire the images for this mosaic, and the pixel scale resolution varies from 381 meters per pixel on the right to 440 meters per pixel on the left. The imager used its near-infrared, green, and blue filters, which helped to reveal highly contrasting craters, ridges, wind streaks, and volcanic plains materials on the surface.

The mosaic covers part of the Iapygia region of the rugged southern highlands of Mars, from approximately 62 degrees east to 78 degrees east longitude and 4 degrees north to 14 degrees south latitude. The largest crater, just below center, is called Fournier and is about 71 miles (114 kilometers) in diameter. The linear feature running from top to bottom of the mosaic just left of center is part of a long irregular cliff (or scarp) system called Oenotria Scopuli, which is part of the circular structure of the large Isidis impact basin to the northeast of this area.

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: 

• explore peaceably and transparently 
• render aid to those in need 
• enable access to scientific data  
• ensure activities do not interfere with those of others 
• preserve historically significant sites and artifacts by developing best practices 

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.

Twice each day, tides ebb and flow through a maze of sandy channels, mudflats, and mangrove forests that flank the 88 islands and islets of Guinea-Bissau’s Bijagós Archipelago (Arquipélago dos Bijagós in Portuguese). Seen from above, the process leads to stark changes to the landscape: around low tide, intertidal mudflats and sandflats emerge from the sea, causing islands to grow significantly before shrinking again hours later.

The perpetual rhythm of the tides sustains outpourings of marine life in an archipelago that, as of 2025, was inscribed as a UNESCO World Heritage site. The site protects the only active deltaic archipelago on Africa’s Atlantic coast, a place where tides, river sediments, coastal upwelling, and coastal currents come together to shape unusually productive and biodiverse island ecosystems.  

UNESCO estimates that the islands support some 870,000 migratory shorebirds, making this one of the most important feeding areas for birds in West Africa along the East Atlantic Flyway. Hundreds of species of birds dine on a potpourri of marine worms, crustaceans, mollusks, and small fish found on mudflats exposed by low tides. During high tides, manatees, dolphins, and schools of fish move closer to the islands, pushing deeper into the mangrove forests that ring them, and tens of thousands of sea turtles swim inland to sandy beaches as they hunt for nesting sites.

A huge population of green sea turtles nests on the tiny island of Poilão, part of the João Vieira and Poilão Marine National Park. After hatching, young turtles make perilous nighttime dashes to the water, often pursued by crabs, lizards, and birds. Once they reach the water, baby sea turtles face an array of predators, including jacks, barracudas, groupers, and snappers that patrol shallow waters as well as tuna, mackerel, sharks, and rays in deeper waters. According to some estimates, less than 1 percent of green sea turtle hatchlings survive to adulthood. 

A 2025 analysis of the region’s tides explored why the archipelago has some of the largest tidal ranges in West Africa. The researchers concluded that the region’s wide, shallow shelf and the estuary’s geometry combine to create a tidal range of up to 7 meters (23 feet), compared to about 1 meter (3 feet) in many other parts of the West African coast. The scientists used altimetry data from the NASA/CNES TOPEX/Poseidon, Jason-1, and Jason-2 satellites to help validate their findings.
