Identical to a previously flown version that was intended as the backup, this new probe will capture shock wave data near the X-59 as it flies faster than the speed of sound, supporting NASA’s Quesst mission.NASA/Jim Ross When you’re testing a cutting-edge NASA aircraft, you need specialized tools to conduct tests and capture data –but if those tools need maintenance, you need to wait until they’re fixed. Unless you have a backup. That’s why NASA recently calibrated a new shock-sensing probe to capture shock wave data when the agency’s X-59 quiet supersonic research aircraft begins its test flights.
When an aircraft flies faster than the speed of sound, it produces shock waves that travel through the air, creating loud sonic booms. The X-59 will divert those shock waves, producing just a quiet supersonic thump. Over the past few weeks, NASA completed calibration flights on a new near-field shock-sensing probe, a cone-shaped device that will capture data on the shock waves that the X-59 will generate.
This shock-sensing probe is mounted to an F-15D research aircraft that will fly very close behind the X-59 to collect the data NASA needs. The new unit will serve as NASA’s primary near-field probe, with an identical model NASA developed last year acting as a backup mounted to an additional F-15B.
The two units mean the X-59 team has a ready alternative if the primary probe needs maintenance or repairs. For flight tests like the X-59’s – where data gathering is crucial and operations revolve around tight timelines, weather conditions, and other variables – backups for critical equipment help to ensure continuity, maintain schedule, and preserve efficiency of operations.
“If something happens to the probe, like a sensor failing, it’s not a quick fix,” said Mike Frederick, principal investigator for the probe at NASA’s Armstrong Flight Research Center in Edwards, California. “The other factor is the aircraft itself. If one needs maintenance, we don’t want to delay X-59 flights.”
To calibrate the new probe, the team measured the shock waves of a NASA F/A-18 research aircraft. Preliminary results indicated that the probe successfully captured pressure changes associated with shock waves, consistent with the team’s expectations. Frederick and his team are now reviewing the data to confirm that it aligns with ground mathematical models and meets the precision standards required for X-59 flights.
Researchers at NASA Armstrong are preparing for additional flights with both the primary and backup probes on their F-15s. Each aircraft will fly supersonic and gather shock wave data from the other. The team is working to validate both the primary and backup probes to confirm full redundancy – in other words, making sure that they have a reliable backup ready to go.

Building for a Better World: Norfolk Students Bring STEM to Life with NASA Partnership
At Norfolk Technical Center in Norfolk, Virginia, carpentry students in Jordan Crawford’s first-year class aren’t just learning how to measure and cut wood—they’re discovering how their skills can serve a greater purpose.
When the NASA Science Activation program’s NASA eClips project—led by the National Institute of Aerospace’s Center for Integrative Science, Technology, Engineering, and Mathematics (STEM) Education (NIA-CISE)—needed help building weather instrument shelters for local schools, Norfolk Public Schools’ Career and Technical Education (CTE) team saw an opportunity to connect students to something bigger than the classroom. The shelters are used to house scientific equipment that K–12 students rely on to collect data using GLOBE (Global Learning and Observations to Benefit the Environment) protocols—a set of standardized, internationally recognized methods for gathering environmental data such as temperature, soil moisture, and cloud cover. These observations contribute to a global citizen science database, giving young learners a meaningful role in real-world environmental research.
Originally, shelters were being ordered from a national supplier to support GLOBE training sessions for teachers in GO (Growth & Opportunity) Virginia Region 5, an economic development region. These training sessions were funded through a generous grant from the Coastal Virginia STEM Hub (COVA STEM Hub), which supports regional collaboration in STEM education. But when the supplier couldn’t keep up with demand, Norfolk Public Schools CTE Specialist Dr. Deborah Marshall offered a bold solution: why not have local students build them?
That’s when the project truly took off. Under the guidance of Jordan Crawford, students took on the challenge of building 20 high-quality shelters in spring 2024, following precise construction plans provided through the GLOBE Program. Materials were funded by the COVA STEM grant, and the students rolled up their sleeves to turn lumber into lasting educational tools for their community.
“As an instructor, you look for opportunities that challenge your students, allow them to do things bigger than themselves, and let them see a project through from start to finish,” Crawford said. “This project allowed my students to hone existing skills and build new ones, and I saw incredible growth not just in craftsmanship but in teamwork. The most rewarding part was seeing the impact of their work in real schools.”
And the students rose to the occasion—taking pride in their work, learning advanced techniques, and developing new confidence. One of the most challenging parts of the build involved crafting the louvers—angled slats on the sides of the shelters needed for proper air circulation. Student Zymere Watts took the lead in designing and building a jig to make sure the louvers could be cut uniformly and precisely for every unit.
“Building the weather shelters was a fun and challenging task that pushed me to strive for perfection with each one,” said student Amir Moore. “After completion, I was delighted to see the faces of the people who were proud and happy with what we built.”
“It was an extreme pleasure working on this project. I would love to work with NIA again,” added LaValle Howard. “I am proud to be a part of this vocational school and team.”
Jaymyson Burden agreed: “It was fun and great to be exposed to the carpentry realm and install them in the real world. It was gratifying to know what we have done has an impact.”
After completing the shelters, the students volunteered to install them at seven Hampton City Schools. Their work completed the full circle—from building the shelters in their carpentry classroom to setting them up where younger students would use them to collect real environmental data.
Their dedication did not go unnoticed. The team was invited to NASA’s Langley Research Center for a behind-the-scenes tour of the NASA Model Shop, where they met Sam James, a Mechanical Engineering Technician and Fabrication Specialist. James showed the students how the same kind of craftsmanship they’d used is essential in the creation of tools and components for NASA missions. They also learned about NASA summer internships and discovered that their hands-on skills could open doors to exciting careers in STEM fields.
“It was an honor to help where we were needed,” said student Josh Hunsucker. “Assembling these gave us a new perspective on the importance of duplication and how each step impacts the result. We’re happy to help wherever or whenever we’re needed—it provides a learning experience for us.”
Kyra Pope summed it up: “It’s been a great amount of work over the past few months, but it pays off—especially when you’re giving back to the community.”
According to Dr. Sharon Bowers, Associate Director and Senior STEM Education Specialist for NIA-CISE, the project demonstrates what’s possible when regional partners come together to empower students and educators alike. “The financial support from COVA STEM Hub supported sustained educator professional learning within our STEM learning ecosystem. Work with the Norfolk Technical Center truly made this a real-world, problem-solving experience. This is just the beginning for more collaborative work that will bring the region together to engage educators and learners in authentic STEM learning experiences.”
This collaboration wasn’t just about building boxes to house thermometers. It was about building bridges—between technical education and science, between high school students and their futures, and between local classrooms and global research. With each shelter they crafted, the students created something that will outlast them, reminding others—and themselves—of what’s possible when learning is hands-on, meaningful, and connected to the world beyond school walls.
