Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA/Lori Losey
The best way to solve a mystery is by gathering evidence and building a case. That’s exactly what NASA researchers are doing with a series of research flights aimed at advancing a sensor for supersonic parachutes. The clues they find could help make these parachutes more reliable and safer for delivering scientific instruments and payloads to Mars.
These investigative research flights are led by the EPIC (Enhancing Parachutes by Instrumenting the Canopy) team at NASA’s Armstrong Fight Research Center in Edwards, California. During a June flight test, a quadrotor aircraft, or drone, air-launched a capsule that deployed a parachute equipped with a sensor. The flexible, strain-measuring sensor attached to the parachute did not interfere with the canopy material, just as the EPIC team had predicted. The sensors also provided data, a bonus for planning upcoming tests.
“Reviewing the research flights will help inform our next steps,” said Matt Kearns, project manager for EPIC at NASA Armstrong. “We are speaking with potential partners to come up with a framework to obtain the data that they are interested in pursuing. Our team members are developing methods for temperature testing the flexible sensors, data analysis, and looking into instrumentation for future tests.”
The flight tests were a first step toward filling gaps in computer models to improve supersonic parachutes. This work could also open the door to future partnerships, including with the aerospace and auto racing industries.
NASA’s Space Technology Mission Directorate (STMD) funds the EPIC work through its Entry Systems Modeling project at NASA’s Ames Research Center in California’s Silicon Valley. The capsule and parachute system were developed by NASA’s Langley Research Center in Hampton, Virginia. NASA Armstrong interns worked with Langley to build and integrate a similar system for testing at NASA Armstrong. An earlier phase of the work focused on finding commercially available flexible strain sensors and developing a bonding method as part of an STMD Early Career Initiative project.

That’s why NASA is investigating potential air taxi materials and designs that could best protect passengers in the event of a crash.
On June 26 at NASA’s Langley Research Center in Hampton, Virginia, researchers dropped a full-scale aircraft body modeled after an air taxi from a tall steel structure, known as a gantry.
The NASA researchers behind this test and a previous one in late 2022 investigated materials that best absorb impact forces, generating data that will enable manufacturers to design safer advanced air mobility aircraft.
“By showcasing elements of a crash alongside how added energy-absorbing technology could help make the aircraft more robust, these tests will help the development of safety regulations for advanced air mobility aircraft, leading to safer designs,” said Justin Littell, test lead, based at Langley.
An aircraft body modeled after an air taxi with weighted test dummies inside is hoisted about 35 feet in the air by cables at NASA’s Langley Research Center in Hampton, Virginia.

It swung forward before crashing to the ground. The impact conditions were like the prior test in 2022, but with the addition of a 10-degree yaw, or twist, to the aircraft’s path. The yaw replicated a certification condition required by Federal Aviation Administration regulations for these kinds of aircraft.
After the drop, researchers began to evaluate how the structure and batteries withstood the impact. As expected, the material failures closely matched predictions from computer simulations, which were updated using data from the 2022 tests.

The aircraft included energy absorbing subfloors, similar to crumple zones in cars, which appeared to crush as intended to help protect the seats inside. The battery experiment involved adding mass to simulate underfloor battery components of air taxis to collect acceleration levels. Once analyzed, the team will share the data and insights with the public to enhance further research and development in this area.
Lessons learned from these tests will help the advanced air mobility industry evaluate the crashworthiness of aircraft designs before flying over communities.
The work is managed by the Revolutionary Vertical Lift Technology project under NASA’s Advanced Air Vehicles Program in support of NASA’s Advanced Air Mobility mission, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA researcher Darren Nash monitors experimental communications equipment on NASA’s Pilatus PC-12 during a flight test over NASA’s Glenn Research Center in Cleveland on April 17, 2025.NASA/Sara Lowthian-Hanna NASA engineers are exploring how the technology used in existing cellphone networks could support the next generation of aviation.
In April and May, researchers at NASA’s Glenn Research Center in Cleveland built two specialized radio systems to study how well fifth-generation cellular network technology, known as 5G, can handle the demands of air taxi communications.
“The goal of this research is to understand how wireless cellphone networks could be leveraged by the aviation industry to enable new frontiers of aviation operations,” said Casey Bakula, lead researcher for the project, who is based at Glenn. “The findings of this work could serve as a blueprint for future aviation communication network providers, like satellite navigation providers and telecommunications companies, and help guide the Federal Aviation Administration’s plan for future advanced air mobility network requirements in cities.”
Instead of developing entirely new standards for air taxi communications, NASA is looking to see if the aviation industry could leverage the expertise, experience, and investments made by the cellular industry towards the development of reliable, secure, and scalable aviation networks. If 5G networks could provide an “80% solution” to the challenge, researchers can focus on identifying the remaining 20% that would need to be adapted to meet the needs of the air taxi industry.
NASA researchers Darren Nash, left, and Brian Kachmar review signal data captured from experimental communications equipment onboard NASA’s Pilatus PC-12 on April 17, 2025.NASA/Sara Lowthian-Hanna 5G networks can manage a lot of data at once and have very low signal transmission delay compared to satellite systems, which could make them ideal for providing location data between aircraft in busy city skies. Ground antennas and networks in cities can help air taxis stay connected as they fly over buildings, making urban flights safer.
To conduct their tests, NASA researchers set up a system that meets current 5G standards and would allow for future improvements in performance. They placed one radio in the agency’s Pilatus PC-12 aircraft and set up another radio on the roof of Glenn’s Aerospace Communications Facility building. With an experimental license from the Federal Aviation Administration (FAA) to conduct flights, the team tested signal transmissions using a radio frequency band the Federal Communications Commission dedicated for the safe testing of drones and other uncrewed aircraft systems.
During testing, NASA’s PC-12 flew various flight patterns near Glenn. The team used some of the flight patterns to measure how the signal could weaken as the aircraft moved away from the ground station. Other patterns focused on identifying areas where nearby buildings might block signals, potentially causing interference or dead zones. The team also studied how the aircraft’s angle and position relative to the ground station affected the quality of the connection.
These initial tests provided the NASA team an opportunity to integrate its new C-Band radio testbed onto the aircraft, verify its basic functionality, and the operation of the corresponding ground station, as well as refine the team’s test procedures. The successful completion of these activities allows the team to begin research on how 5G standards and technologies could be utilized in existing aviation bands to provide air-to-ground and aircraft-to-aircraft communications services.
Experimental communications equipment is secure and ready for flight test evaluation in the back of NASA’s Pilatus PC-12 at NASA’s Glenn Research Center in Cleveland on April 17, 2025. NASA/Sara Lowthian-Hanna In addition to meeting these initial test objectives, the team also recorded and verified the presence of propeller modulation. This is a form of signal degradation caused by the propeller blades of the aircraft partially blocking radio signals as they rotate. The effect becomes more significant as aircraft fly at the lower altitudes air taxis are expected to operate. The airframe configuration and number of propellers on some of the new air taxi models may cause increased propeller modulation effects, so NASA researchers will study this further.
NASA research will provide baseline performance data that the agency will share with the FAA and the advanced air mobility sector of the aviation industry, which explores new air transportation options. Future research looking into cellular network usage will focus on issues such as maximum data speeds, signal-to-noise ratios, and synchronization between aircraft and ground systems. Researchers will be able to use NASA’s baseline data to measure the potential of new changes or features to communications systems.
Future aircraft will need to carry essential communications systems for command and control, passenger safety, and coordination with other aircraft to avoid collisions. Reliable wireless networks offer the possibility for safe operations of air taxis, particular in cities and other crowded areas.
This work is led by NASAs Air Mobility Pathfinders project under the Airspace Operations and Safety Program in support of NASA’s Advanced Air Mobility mission.
