In the future, aircraft with long, thin wings supported by aerodynamic braces could help airlines save on fuel costs. But those same wings could be susceptible to ice buildup. NASA researchers are currently working to determine if such an issue exists, and how it could be addressed.

In the historic Icing Research Tunnel at NASA’s Glenn Research Center in Cleveland, scientists and engineers are testing a concept for a transonic truss-braced wing. Their goal: to collect important data to inform the design of these potential efficient aircraft of the future.

A transonic truss-braced wing generates less drag in flight compared to today’s aircraft wings, requiring an aircraft to burn less fuel. This revolutionary design could make the wing more prone to ice buildup, so it must undergo a series of rigorous tests to predict its safety and performance. The data the research team has collected so far suggests large sections of the frontmost part of the wing (also known as the leading edge) will require an ice protection system, similar to those found on some commercial aircraft.

NASA Glenn can simulate icing conditions in its Icing Research Tunnel to identify potential challenges for new aircraft designs. These tests provide important information about how ice builds up on wings and can help identify the most critical icing conditions for safety. All commercial aircraft must be approved by the Federal Aviation Administration to operate in all kinds of weather.

Because of the thinness of transonic truss-braced wing design, ice tends to build up during cold conditions, as seen during a test in October 2024. Researchers at NASA’s Glenn Research Center in Cleveland conducted another test campaign in March 2025, collecting important data to ensure safety.

This research is part of NASA’s work to mature transonic truss-braced technology by looking at issues including safety and how future aircraft could be integrated into U.S. aviation infrastructure. Boeing is also working with NASA to build, test, and fly the X-66, a full-sized demonstrator aircraft with transonic truss-braced wings. Because the experimental aircraft will not be flown in icy conditions, tests in the Icing Research Tunnel are providing answers to questions about ice buildup.

This work advances NASA’s role in developing ultra-efficient airliner technologies that are economically, operationally, and environmentally sustainable. For about two decades, NASA has invested in research aimed at advancing transonic truss-braced wing technology to the point where private sector aeronautics companies can integrate it into commercial aircraft configurations. NASA invests in this research through initiatives including its Advanced Air Transport Technology project, which investigates specific performance aspects of transonic truss-braced wing concepts, such as icing. The Advanced Air Transport Technology project is part of NASA’s Advanced Air Vehicles Program.

Sols 4488-4490: Progress Through the Ankle-Breaking Terrain (West of Texoli Butte, Climbing Southward)

A grayscale photo from the Martian surface shows the Curiosity rover’s robotic arm reaching down to investigate a targeted rock. The surrounding terrain is very rocky and uneven, with stones of varied shapes and sizes pushing up out of the ground, everything a similar dark shade of gray. The soil between the rocks appears wavy in many places, as if sculpted by wind or water, and most of the rocks look like they have formed from horizontal layers stacking on one another, in the relatively short elevation they rise from the surface, looking like 3D versions of hills indicated on a topographic map. The rover’s arm extends down to the center of the image from the upper left corner of the frame where, at a pivot point, it bends at roughly 90-degree angle toward the left side of the image and out of the frame. The arm itself is bright-toned, nearly white, with a metallic sheen; the pivot point and the boxy suite of instruments at the end of the arm near the ground are mainly dark gray or black, with multiple knobby protrusions.
NASA’s Mars rover Curiosity captured this image showing its robotic arm in action; the view also illustrates bedding on a light-toned bedrock block of the layered sulfate-bearing unit. Curiosity acquired the image using its Right Navigation Camera on March 20, 2025 — sol 4486, or Martian day 4,486 of the Mars Science Laboratory mission — at 15:18:42 UTC.

Earth planning date: Friday, March 21, 2025

It’s the start of spring here in the Northern Hemisphere on Earth, but in Gale Crater on Mars our rover is still heading into the depths of Martian winter. We’re just a few weeks away from Mars’ aphelion — the time when it’s farthest from the Sun. The Mars-Sun distance varies more significantly than the Earth-Sun distance because of the greater eccentricity of Mars’ orbit, and its effect on the Martian weather is correspondingly more important.

As my colleague mentioned in the previous blog post, the layered sulfate bedrock in this region is broken up into large blocks that often make the driving tough going. The drive in the sol 4486 plan went very well, however, moving Curiosity nearly 35 meters (about 115 feet) southward and upward. Our new workspace is in one of the “light-toned” stripes that can be seen in the orbital imagery and is correspondingly full of light-toned laminated blocks typical of what we’ve seen before in this geologic unit.

For the second plan in a row we were also able to use the rover arm, due to the rover having parked in a stable position — not always a given in this terrain! This enabled us to plan a pair of compositional measurements by the APXS on a bedrock target (“Solstice Canyon”) to assess both the bedrock composition after dust removal and the effect of the ubiquitous dust on the instrument at other locations where the rock cannot be brushed. Our other compositional measurement tool, the LIBS, was also recruited for a co-targeted measurement on Solstice Canyon.

The second LIBS measurement and a MAHLI observation went to the one distinctive, potentially diagenetic, feature visible among all of the light-toned workspace blocks, a small grayish patch that looks like a vein or a coating in the images available at planning (“Black Oak”). The planned observations will give us both the composition and morphology of it in much greater detail.

A long-distance RMI imaging mosaic was planned to investigate some ridges on an as-yet-unnamed butte off to the west. The ridges may be evidence of the same type of diagenetic activity that produced the boxwork structures that are the next major science target for Curiosity. A passive spectral raster was also planned for a potential boxwork region. As we won’t be able to rove to every potential boxwork on Aeolis Mons, longer-distance views such as these can give us a sense of how widespread the boxwork-forming activity may have been.

Mastcam imaging included some follow-up on a hummocky sedimentary feature (“Pino Alto”) and documentation of textures in the nearby local bedrock (“Piedra Blanca”) as well as documentation imagery for the two LIBS targets.

Finally, the modern Martian atmosphere was investigated with measurements by APXS and the ChemCam passive imager to track abundances of argon and oxygen, respectively, as they vary with the Martian seasons

Engineering Reality: Lee Bingham Leads Lunar Surface Simulation Support for Artemis Campaign

Engineering Reality: Lee Bingham Leads Lunar Surface Simulation Support for Artemis Campaign

If you design a new tool for use on Earth, it is easy to test and practice using that tool in its intended environment. But what if that tool is destined for lunar orbit or will be used by astronauts on the surface of the Moon?

NASA’s Simulation and Graphics Branch can help with that. Based at Johnson Space Center in Houston, the branch’s high-fidelity, real-time graphical simulations support in-depth engineering analyses and crew training, ensuring the safety, efficiency, and success of complex space endeavors before execution. The team manages multiple facilities that provide these simulations, including the Prototype Immersive Technologies (PIT) Lab, Virtual Reality Training Lab, and the Systems Engineering Simulator (SES).

Lee Bingham is an aerospace engineer on the simulation and graphics team. His work includes developing simulations and visualizations for the NASA Exploration Systems Simulations team and providing technical guidance on simulation and graphics integration for branch-managed facilities. He also leads the branch’s human-in-the-loop Test Sim and Graphics Team, the Digital Lunar Exploration Sites Unreal Simulation Tool (DUST), and the Lunar Surface Mixed-Reality with the Active Response Gravity Offload System (ARGOS) projects.

Bingham is particularly proud of his contributions to DUST, which provides a 3D visualization of the Moon’s South Pole and received Johnson’s Exceptional Software of the Year Award in 2024. “It was designed for use as an early reference to enable candidate vendors to perform initial studies of the lunar terrain and lighting in support of the Strategy and Architecture Office, human landing system, and the Extravehicular Activity and Human Surface Mobility Program,” Bingham explained. DUST has supported several human-in-the-loop studies for NASA. It has also been shared with external collaborators and made available to the public through the NASA Software Catalog.  

Bingham has kept busy during his nearly nine years at Johnson and said learning to manage and balance support for multiple projects and customers was very challenging at first. “I would say ‘yes’ to pretty much anything anyone asked me to do and would end up burning myself out by working extra-long hours to meet milestones and deliverables,” he said. “It has been important to maintain a good work-life balance and avoid overcommitting myself while meeting demanding expectations.”

Bingham has also learned the importance of teamwork and collaboration. “You can’t be an expert at everything or do everything yourself,” he said. “Develop your skills, practice them regularly, and master them over time but be willing to ask for help and advice. And be sure to recognize and acknowledge your coworkers and teammates when they go above and beyond or achieve something remarkable.”

He hopes that the Artemis Generation will be motivated to tackle difficult challenges and further NASA’s mission to benefit humanity. “Be sure to learn from those who came before you, but be bold and unafraid to innovate,” he advised.
