NASA and Boeing have completed wind tunnel testing to study an innovative advanced aircraft design intended to improve aerodynamic efficiency.

A truss-braced wing configuration, involving a long, thin wing with aerodynamically shaped structural supports, has the potential to reduce fuel and operational costs for future airliners, which is why NASA has collaborated with Boeing to advance the design.

But this kind of wing would be much more than a simple tweak to existing designs – for an aircraft the size of a passenger jet, it would be a revolutionary redesign, requiring extensive study from NASA and Boeing.

The most recent round of testing used a complex wind tunnel model to collect data on how air flows around a truss-braced wing model and the forces that would be exerted on such a wing in flight.

The test used a semispan model – essentially half an aircraft mounted on a wind tunnel floor. The model has features built in to simulate the mechanisms that increase the amount of lift a wing produces. By adjusting the model’s slats, flaps, and other moving control surfaces, the team can configure it to the low speed, high-lift settings of takeoff and landing conditions.

The model is part of a collaboration to test what’s known as Boeing’s Subsonic Ultra Green Aircraft Research (SUGAR) concept.

In December, teams completed testing of the model wind tunnel operated by the company QinetiQ in Farnborough, England. This large wind tunnel uses pressurized conditions to predict airplane behavior in takeoff and landing conditions.

The large size of the tunnel gives the model fidelity to better predict the behavior of a plane in flight. This capability allowed the team to confidently assess aerodynamic performance.

NASA and Boeing research teams analyzed data in real time to ensure the model performed as expected. Researchers are still reviewing the full results, but the test has already added valuable information to a growing body of research aimed at reducing fuel use in future aircraft designs.

The testing was just the latest stop for this research. NASA and Boeing have tested the concept at multiple NASA facilities to collect data as they work to build a comprehensive understanding of this advanced airframe concept.

This collaboration serves as an example of how NASA serves as an incubator for breakthrough technology with profound commercial applications. The transonic truss-braced wing concept originated from NASA aeronautics-supported research and NASA and Boeing engineers have worked together, test-by-test, to move this wing design from an idea to a practical reality.

The work began in NASA’s Advanced Air Vehicles Program and continues as part of the Subsonic Flight Demonstrator project under the Integrated Aviation Systems Program in the agency’s Aeronautics Research Mission Directorate.

NASA Demonstrates New Prescribed Burn Capability for Spaceport 

2026-04-29 14:27

A large tower of thick white and gray smoke rises behind NASA’s Vehicle Assembly Building at Kennedy Space Center, filling much of the sky. The smoke originates near a launch pad structure with tall cranes beside it. In the foreground, an empty parking lot and several parked vehicles sit under a clear blue sky.

Anyone who has seen a launch at NASA’s Kennedy Space Center in Florida knows the agency’s pursuit of the stars involves some smoke and fire. Sometimes, however, the smoke doesn’t come from the rockets that propel astronauts beyond Earth’s bounds.

That was the case during the second weekend of January 2026, when NASA teamed up with the U.S. Fish and Wildlife Service and commercial space partners to intentionally ignite around 2,600 acres of scrub habitat at NASA Kennedy during an active launch countdown, a first for the busiest spaceport in the world.

Staff from NASA Kennedy’s Spaceport Integration Directorate oversaw two prescribed burns conducted by the Service. The larger burn affected around 1,400 acres on the northeast corner of the center, known as Happy Creek — a key habitat for the federally protected Florida scrub-jay and other wildlife that rely on periodic wildfires to thrive.

The other prescribed burn affected a 1,200-acre section east of Kennedy Parkway and south of the center’s industrial zone, near the spaceport’s seven-story headquarters building, as well as iconic facilities critical to NASA’s past and future space efforts like the Neil A. Armstrong Operations and Checkout Building and the Space Systems Processing Facility.

Historically, the center paused launch operations when using fire as a land management tool within NASA Kennedy’s secure area or the Merritt Island National Wildlife Refuge, which surrounds it. However, with Kennedy’s spaceport surpassing 100 successful liftoffs for the first time in 2025, and with the launch cadence expected to continue climbing in the years to come, officials at both agencies recognized the need to adapt.

NASA and U.S. Fish and Wildlife Service personnel gather at the United States Fish and Wildlife Service off A. Max Brewer Memorial Parkway on Friday, Jan. 9, 2026, in Titusville, Florida to finalize the plan prior to the prescribed burn.

“As more launches occur at Kennedy, the need for proper land management at the refuge has never been greater,” said Greg Gaddis, the center’s senior operations manager for the spaceport. “We must find new ways to lessen the amount of fire fuel on the ground while also keeping pace with the launch needs of our government and commercial partners. Otherwise, an unexpected lightning bolt or some other fire-starter could be catastrophic for America’s space ambitions, as well as the private space industry.”

The increasing launch cadence is one of many factors the prescribed burn manager — also known as the burn boss — must consider when deciding when and where to conduct a prescribed burn at the spaceport. Another critical factor is weather conditions, especially during Florida’s dry season, where constant breeze from the nearby Atlantic Ocean can quickly turn a small fire into a large one. This could potentially pose a significant risk to plant and animal species at the refuge, as well as to the center’s launch infrastructure.

Safety remains the paramount concern. The center’s Space Operations Office worked directly with the Service and the launch mission partners during the burn.

Prior to the Service setting prescribed burns with air and land resources, Kennedy officials reviewed forecasted wind patterns and developed plans to protect workers in buildings affected by the smoke. The center issued smoke warnings, temporarily relocated some personnel, and allowed others to work remotely during the burns. The smoke also caused intermittent closures of some of the center’s main roads and entrances throughout the weekend for safety reasons.

A stream of ignited fuel sprays from a piece of equipment toward dense vegetation, sending flames into the brush as thick gray smoke rises into the sky. In the foreground, tall grasses and palmettos line a dirt path, while two off‑road firefighting vehicles are parked on the right side of the scene.
Torches mounted onto vehicles are used to intentionally set over 2,600 acres of the Merritt Island National Wildlife Refuge on fire on Friday, Jan. 9, 2026. Those areas are located inside Kennedy Space Center’s restricted area and occurred during an active launch countdown, the first time that’s ever happened at NASA Kennedy.
NASA/Tim Kozusko

“To do is to learn, and we all learn each day,” said Shawn Sullivan, assistant fire management officer for the Service’s Region 4 and the designated burn boss. “I stood in awe of the people working around me. To listen to the coordination between specialized groups and witness great individual effort was quite an experience.”

Conducting prescribed burns every two or three years is optimal for maintaining the health and resilience of the refuge, especially for wildlife like the Florida scrub-jay, which has adapted to periodic fires. Determining when and where to conduct these burns is one of the most challenging parts for the burn boss and the officials responsible for operating the spaceport. The amount of vegetation in those areas is often a deciding factor when choosing what to burn.

“We want to make sure those areas don’t get clogged up, making it more difficult for firefighters to gain access if they have to protect launch pads or any other infrastructure from a wildfire,” Gaddis added. “It also leaves less fuel a wildfire can use to grow, and that’s always a big help for first responders working to put a fire out.”

Fires Rage in Georgia

An extreme drought that has gripped the Southeast for months helped fuel two large, destructive, human-caused wildland fires in southern Georgia in April 2026. The Pineland Road and Highway 82 fires together burned more than 50,000 acres (20,000 hectares) as of April 28, according to the Georgia Forestry Commission.

Satellite images of the fires captured by Landsat 8 show charred forests and residential areas in and around Atkinson (above) and Fruitland (below). The images are false color (bands 7-5-4), in which burned areas appear gray and vegetated areas green. The infrared signatures of actively burning fire fronts are orange. By April 25, the fires had destroyed more than 120 homes—the most lost to wildfire in the state’s history, according to news reports.

The Highway 82 blaze started on April 18 with a spark from a welding operation, and the Pineland Road fire ignited three days later after a mylar balloon collided with power lines. Both blazes spread rapidly amid blustery winds in areas that were parched by months of limited rainfall. Fallen trees and limbs left by Hurricane Helene in September 2024 also helped fuel the fires, according to forestry officials.

Heavy rains helped firefighters battle the blazes in recent days, but the Pineland Road fire remained 23 percent contained and the Highway 82 fire 32 percent contained on April 28, the forestry commission reported. Hundreds of firefighting personnel are confronting the fires with equipment in the air and on the ground.

NASA’s satellite and aircraft data are part of a global system of observations used to track fire behavior, analyze emerging trends, and develop technology that operational agencies can use to manage wildfires across the United States. Among the real-time wildfire monitoring tools that NASA makes available are FIRMS (Fire Information for Resource Management System), the Worldview browser, and the Fire Event Explorer.
