NASA’s X-59 quiet supersonic research aircraft successfully completed a critical series of tests in which the airplane was put through its paces for cruising high above the California desert – all without ever leaving the ground.

“The idea behind these tests is to command the airplane’s subsystems and flight computer to function as if it is flying,” said Yohan Lin, the X-59’s lead avionics engineer at NASA’s Armstrong Flight Research Center in Edwards, California.

The goal of ground-based simulation testing was to make sure the hardware and software that will allow the X-59 to fly safely are properly working together and able to handle any unexpected problems.

Any new aircraft is a combination of systems, and identifying the little adjustments required to optimize performance is an important step in a disciplined approach toward flight.

“We thought we might find a few things during the tests that would prompt us to go back and tweak them to work better, especially with some of the software, and that’s what we wound up experiencing. So, these tests were very helpful,” Lin said.

Completing the tests marks another milestone off the checklist of things to do before the X-59 makes its first flight this year, continuing NASA’s Quesst mission to help enable commercial supersonic air travel over land.

Simulating the Sky

During the testing, engineers from NASA and contractor Lockheed Martin turned on most of the X-59’s systems, leaving the engine off. For example, if the pilot moved the control stick a certain way, the flight computer moved the aircraft’s rudder or other control surfaces, just as it would in flight.

At the same time, the airplane was electronically connected to a ground computer that sends simulated signals – which the X-59 interpreted as real – such as changes in altitude, speed, temperature, or the health of various systems.

Sitting in the cockpit, the pilot “flew” the aircraft to see how the airplane would respond.

“These were simple maneuvers, nothing too crazy,” Lin said. “We would then inject failures into the airplane to see how it would respond. Would the system compensate for the failure? Was the pilot able to recover?”

Unlike in typical astronaut training simulations, where flight crews do not know what scenarios they might encounter, the X-59 pilots mostly knew what the aircraft would experience during every test and even helped plan them to better focus on the aircraft systems’ response.

Aluminum vs. Iron

In aircraft development, this work is known as “iron bird” testing, named for a simple metal frame on which representations of the aircraft’s subsystems are installed, connected, and checked out.

Building such a testbed is a common practice for development programs in which many aircraft will be manufactured. But since the X-59 is a one-of-a-kind airplane, officials decided it was better and less expensive to use the aircraft itself.

As a result, engineers dubbed this series of exercises “aluminum bird” testing, since that’s the metal the X-59 is mostly made of.

So, instead of testing an “iron bird” with copies of an aircraft’s systems on a non-descript frame, the “aluminum bird” used the actual aircraft and its systems, which in turn meant the test results gave everyone higher confidence in the design,

“It’s a perfect example of the old tried and true adage in aviation that says ‘Test what you fly. Fly what you test,’” Lin said.

Still Ahead for the X-59

With aluminum bird testing in the rearview mirror, the next milestone on the X-59’s path to first flight is take the airplane out on the taxiways at the airport adjacent to Lockheed Martin’s Skunk Works facility in Palmdale, California, where the X-59 was built. First flight would follow those taxi tests.

Already in the X-59’s logbook since the fully assembled and painted airplane made its public debut in January 2024:

  • Testing the aircraft’s ability to maintain a certain speed while flying, essentially a check of the X-59’s version of cruise control.

NASA Studies Wind Effects and Aircraft Tracking with Joby Aircraft

Preparations for Next Moonwalk Simulations Underway (and Underwater)

A yellow traffic cone and a black tripod with black testing instruments stands in the foreground on a concrete pad with a desert landscape, power lines, and a black and white aircraft in the background. The aircraft has six black propellors that sit on white arms and connect to the aircraft body, which has black doors and is pod-shaped. The aircraft sits on three small wheels.

NASA is collecting information during this study to help advance future air taxi flights, especially those occurring in cities, to track aircraft moving through traffic corridors and around landing zones.
NASA/Genaro Vavuris

NASA engineers began using a network of ground sensors in March to collect data from an experimental air taxi to evaluate how to safely integrate such vehicles into airspace above cities – in all kinds of weather.

Researchers will use the campaign to help improve tools to assist with collision avoidance and landing operations and ensure safe and efficient air taxi operations in various weather conditions.

For years, NASA has looked at how wind shaped by terrain, including buildings in urban areas, can affect new types of aircraft. The latest test, which is gathering data from a Joby Aviation demonstrator aircraft, looks at another kind of wind – that which is generated by the aircraft themselves.

Joby flew its air taxi demonstrator over NASA’s ground sensor array near the agency’s Armstrong Flight Research Center in Edwards, California producing air flow data. The Joby aircraft has six rotors that allow for vertical takeoffs and landings, and tilt to provide lift in flight. Researchers focused on the air pushed by the propellers, which rolls into turbulent, circular patterns of wind.

Five orange traffic cones and barriers sit in front of a large white box in the foreground. In the background, a man wearing jeans and a black sweatshirt stands in front of a black laptop. Behind him, there are several cream-colored trailers, other construction equipment, and a few cars.

NASA/Genaro Vavuris

This rolling wind can affect the aircraft’s performance, especially when it’s close to the ground, as well as others flying in the vicinity and people on the ground. Such wind turbulence is difficult to measure, so NASA enhanced its sensors with a new type of lidar – a system that uses lasers to measure precise distances – and that can map out the shapes of wind features.

“The design of this new type of aircraft, paired with the NASA lidar technology during this study, warrants a better understanding of possible wind and turbulence effects that can influence safe and efficient flights,” said Grady Koch, lead for this research effort, from NASA’s Langley Research Center in Hampton, Virginia.

Data to Improve Aircraft Tracking

NASA also set up a second array of ground nodes including radar, cameras, and microphones in the same location as the sensors to provide additional data on the aircraft. These nodes will collect tracking data during routine flights for several months.

The agency will use the data gathered from these ground nodes to demonstrate the tracking capabilities and functions of its “distributed sensing” technology, which involves embedding multiple sensors in an area where aircraft are operating.

This technology will be important for future air taxi flights, especially those occurring in cities by tracking aircraft moving through traffic corridors and around landing zones. Distributed sensing has the potential to enhance collision avoidance systems, air traffic management, ground-based landing sensors, and more.

“Our early work on a distributed network of sensors, and through this study, gives us the opportunity to test new technologies that can someday assist in airspace monitoring and collision avoidance above cities,” said George Gorospe, lead for this effort from NASA’s Ames Research Center in California’s Silicon Valley.

Using this data from an experimental air taxi aircraft, NASA will further develop the technology needed to help create safer air taxi flights in high-traffic areas. Both of these efforts will benefit the companies working to bring air taxis and drones safely into the airspace.

The work is led by NASA’s Transformational Tools and Technologies and Convergent Aeronautics Solutions projects under the Transformative Aeronautics Concepts program in support of NASA’s Advanced Air Mobility mission. NASA’s Advanced Air Mobility mission seeks to deliver data to guide the industry’s development of electric air taxis and drones.

The G-IV aircraft flies overhead in the Mojave Desert near NASA’s Armstrong Flight Research Center in Edwards, California. Baseline flights like this one occurred in June 2024, and future flights in service of science research will benefit from the installment of the Soxnav navigational system, developed in collaboration with NASA’s Jet Propulsion Laboratory in Southern California and the Bay Area Environmental Research Institute in California’s Silicon Valley. This navigational system provides precise, economical aircraft guidance for a variety of aircraft types moving at high speeds.
NASA/Carla Thomas

NASA and its partners recently tested an aircraft guidance system that could help planes maintain a precise course even while flying at high speeds up to 500 mph. The instrument is Soxnav, the culmination of more than 30 years of development of aircraft navigation systems.

NASA’s G-IV aircraft flew its first mission to test this navigational system from NASA’s Armstrong Flight Research Center in Edwards, California, in December 2024. The team was composed of engineers from NASA Armstrong, NASA’s Jet Propulsion Laboratory in Southern California, and the Bay Area Environmental Research Institute (BAERI) in California’s Silicon Valley.

“The objective was to demonstrate this new system can keep a high-speed aircraft within just a few feet of its target track, and to keep it there better than 90% of the time,” said John Sonntag, BAERI independent consultant co-developer of Soxnav.

With 3D automated steering guidance, Soxnav provides pilots with a precision approach aid for landing in poor visibility. Previous generations of navigational systems laid the technical baseline for Soxnav’s modern, compact, and automated iteration.

“The G-IV is currently equipped with a standard autopilot system,” said Joe Piotrowski Jr., operations engineer for the G-IV. “But Soxnav will be able to create the exact level flight required for Next Generation Airborne Synthetic Aperture Radar (AirSAR-NG) mission success.”

A man crouches on the floor inside an aircraft while he leans over a metal instrument rack installed onboard. One hand supports the instrument panel while his other fiddles with a component of the instrument. He has a gray jacket on and short black hair.
Jose “Manny” Rodriguez adjusts the Soxnav instrument onboard the G-IV aircraft in December 2024. As part of the team of experts, Rodriguez ensures that the electronic components of this instrument are installed efficiently. His expertise will help bring the innovative navigational guidance of the Soxnav system to the G-IV and the wider airborne science fleet at NASA. Precision guidance provided by the Soxnav enables research aircraft like the G-IV to collect more accurate, more reliable Earth science data to scientists on the ground.
NASA/Steve Freeman

Guided by Soxnav, the G-IV may be able to deliver better, more abundant, and less expensive scientific information. For instance, the navigation tool optimizes observations by AirSAR-NG, an instrument that uses three radars simultaneously to observe subtle changes in the Earth’s surface. Together with the Soxnav system, these three radars provide enhanced and more accurate data about Earth science.

“With the data that can be collected from science flights equipped with the Soxnav instrument, NASA can provide the general public with better support for natural disasters, tracking of food and water supplies, as well as general Earth data about how the environment is changing,” Piotrowski said.

Ultimately, this economical flight guidance system is intended to be used by a variety of aircraft types and support a variety of present and future airborne sensors. “The Soxnav system is important for all of NASA’s Airborne Science platforms,” said Fran Becker, project manager for the G-IV AirSAR-NG project at NASA Armstrong. “The intent is for the system to be utilized by any airborne science platform and satisfy each mission’s goals for data collection.”

In conjunction with the other instruments outfitting the fleet of airborne science aircraft, Soxnav facilitates the generation of more abundant and higher quality scientific data about planet Earth. With extreme weather events becoming increasingly common, quality Earth science data can improve our understanding of our home planet to address the challenges we face today, and to prepare for future weather events.

“Soxnav enables better data collection for people who can use that information to safeguard and improve the lives of future generations,” Sonntag said.

NASA’s Sustainable Flight Demonstrator (SFD) project recently concluded wind tunnel tests of its X-66 semi-span model in partnership with Boeing. The model, designed to represent half the aircraft, allows the research team to generate high-quality data about the aerodynamic forces that would affect the actual X-66.

Test results will help researchers identify areas where they can refine the X-66 design – potentially reducing drag, enhancing fuel efficiency, or adjusting the vehicle shape for better flying qualities.

Tests on the Boeing-built X-66 semi-span model were completed at NASA’s Ames Research Center in California’s Silicon Valley in its 11-Foot Transonic Unitary Plan Facility. The model underwent tests representing expected flight conditions so the team could obtain engineering information to influence the design of the aircraft’s wing and provide data for flight simulators.

Pressure points, which are drilled holes with data sensors attached, are installed along the edge of the wing and allow engineers to understand the characteristics of airflow and will influence the final design of the wing.
NASA/Brandon Torres Navarrete

Semi-span tests take advantage of symmetry. The forces and behaviors on a model of half an aircraft mirror those on the other half. By using a larger half of the model, engineers increase the number of surface pressure measurements. Various sensors were placed on the wing to measure forces and movements to calculate lift, drag, stability, and other important characteristics.

The semi-span tests follow earlier wind tunnel work at NASA’s Langley Research Center in Hampton, Virginia, using a smaller model of the entire aircraft. Engineers will study the data from all of the X-66 wind tunnel tests to determine any design changes that should be made before fabrication begins on the wing that will be used on the X-66 itself.

The SFD project is NASA’s effort to develop more efficient aircraft configurations as the nation moves toward aviation that’s more economically, societally, and environmentally sustainable. The project seeks to provide information to inform the next generation of single-aisle airliners, the most common aircraft in commercial aviation fleets around the world.  Boeing and NASA are partnering to develop the X-66 experimental demonstrator aircraft.

NASA Radar Imagery Reveals Details About Los Angeles-Area Landslides

A topographic map of Rancho Palos Verdes, CA (Sept. 18–Oct. 17, 2024) shows landslide velocity in cm/week, with red areas moving fastest (≥10 cm/week). The slide extends beyond the 2007 boundary toward Abalone Cove. An arrow marks the landslide direction southward.
NASA’s UAVSAR airborne radar instrument captured data in fall 2024 showing the motion of landslides on the Palos Verdes Peninsula following record-breaking rainfall in Southern California in 2023 and another heavy-precipitation winter in 2024. Darker red indicates faster motion.
NASA Earth Observatory

Analysis of data from NASA radar aboard an airplane shows that the decades-old active landslide area on the Palos Verdes Peninsula has expanded.

Researchers at NASA’s Jet Propulsion Laboratory in Southern California used data from an airborne radar to measure the movement of the slow-moving landslides on the Palos Verdes Peninsula in Los Angeles County. The analysis determined that, during a four-week period in the fall of 2024, land in the residential area slid toward the ocean by as much as 4 inches (10 centimeters) per week.

Portions of the peninsula, which juts into the Pacific Ocean just south of the city of Los Angeles, are part of an ancient complex of landslides and has been moving for at least the past six decades, affecting hundreds of buildings in local communities. The motion accelerated, and the active area expanded following record-breaking rainfall in Southern California in 2023 and heavy precipitation in early 2024.

To create this visualization, the Advanced Rapid Imaging and Analysis (ARIA) team used data from four flights of NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) that took place between Sept. 18 and Oct. 17. The UAVSAR instrument was mounted to a Gulfstream III jet flown out of NASA’s Armstrong Flight Research Center in Edwards, California, and the four flights were planned to estimate the speed and direction of the landslides in three dimensions.

In the image above, colors indicate how fast parts of the landslide complex were moving in late September and October, with the darkest reds indicating the highest speeds. The arrows represent the direction of horizontal motion. The white solid lines are the boundaries of the active landslide area as defined in 2007 by the California Geological Survey.

“In effect, we’re seeing that the footprint of land experiencing significant impacts has expanded, and the speed is more than enough to put human life and infrastructure at risk,” said Alexander Handwerger, the JPL landslide scientist who performed the analysis.

The insights from the UAVSAR flights were part of a package of analyses by the ARIA team that also used data from ESA’s (the European Space Agency’s) Copernicus Sentinel-1A/B satellites. The analyses were provided to California officials to support the state’s response to the landslides and made available to the public at NASA’s Disaster Mapping Portal.

Handwerger is also the principal investigator for NASA’s upcoming Landslide Climate Change Experiment, which will use airborne radar to study how extreme wet or dry precipitation patterns influence landslides. The investigation will include flights over coastal slopes spanning the California coastline.

More About ARIA, UAVSAR

The ARIA mission is a collaboration between JPL and Caltech, which manages JPL for NASA, to leverage radar and optical remote-sensing, GPS, and seismic observations for science as well as to aid in disaster response. The project investigates the processes and impacts of earthquakes, volcanoes, landslides, fires, subsurface fluid movement, and other natural hazards.

UAVSAR has flown thousands of radar missions around the world since 2007, studying phenomena such as glaciers and ice sheets, vegetation in ecosystems, and natural hazards like earthquakes, volcanoes, and landslides.

Equipped with state-of-the-art technology to test and evaluate communication, navigation, and surveillance systems NASA’s Pilatus PC-12 performs touch-and-go maneuvers over a runway at NASA’s Armstrong Flight Research Center in Edwards, California on Sept. 23, 2024. Researchers will use the data to understand Automatic Dependent Surveillance-Broadcast (ADS-B) signal loss scenarios for air taxi flights in urban areas. To prepare for ADS-B test flights pilots and crew from NASA Armstrong and NASA’s Glenn Research Center in Cleveland, ran a series of familiarization flights. These flights included several approach and landings, with an emphasis on avionics, medium altitude air-work with steep turns, slow flight and stall demonstrations.

As air taxis, drones, and other innovative aircraft enter U.S. airspace, systems that communicate an aircraft’s location will be critical to ensure air traffic safety.

The Federal Aviation Administration (FAA) requires aircraft to communicate their locations to other aircraft and air traffic control in real time using an Automatic Dependent Surveillance-Broadcast (ADS-B) system. NASA is currently evaluating an ADS-B system’s ability to prevent collisions in a simulated urban environment. Using NASA’s Pilatus PC-12 aircraft, researchers are investigating how these systems could handle the demands of air taxis flying at low altitudes through cities.  

When operating in urban areas, one particular challenge for ADS-B systems is consistent signal coverage. Like losing cell-phone signal, air taxis flying through densely populated areas may have trouble maintaining ADS-B signals due to distance or interference. If that happens, those vehicles become less visible to air traffic control and other aircraft in the area, increasing the likelihood of collisions.

NASA/Steve Freeman

To simulate the conditions of an urban flight area and better understand signal loss patterns, NASA researchers established a test zone at NASA’s Armstrong Flight Research Center in Edwards, California, on Sept. 23 and 24, 2024.

Flying in the agency’s Pilatus PC-12 in a grid pattern over four ADS-B stations, researchers collected data on signal coverage from multiple ground locations and equipment configurations. Researchers were able to pinpoint where signal dropouts occurred from the strategically placed ground stations in connection to the plane’s altitude and distance from the stations. This data will inform future placement of additional ground stations to enhance signal boosting coverage.  

“Like all antennas, those used for ADS-B signal reception do not have a constant pattern,” said Brad Snelling, vehicle test team chief engineer for NASA’s Air Mobility Pathfinders project. “There are certain areas where the terrain will block ADS-B signals and depending on the type of antenna and location characteristics, there are also flight elevation angles where reception can cause signal dropouts,” Snelling said. “This would mean we need to place additional ground stations at multiple locations to boost the signal for future test flights. We can use the test results to help us configure the equipment to reduce signal loss when we conduct future air taxi flight tests.”

The September flights at NASA Armstrong built upon earlier tests of ADS-B in different environments. In June, researchers at NASA’s Glenn Research Center in Cleveland flew the Pilatus PC-12 and found a consistent ADS-B signal between the aircraft and communications antennas mounted on the roof of the center’s Aerospace Communications Facility. Data from these flights helped researchers plan out the recent tests at NASA Armstrong. In December 2020, test flights performed under NASA’s Advanced Air Mobility National Campaign used an OH-58C Kiowa helicopter and ground-based ADS-B stations at NASA Armstrong to collect baseline signal information.

NASA’s research in ADS-B signals and other communication, navigation, and surveillance systems will help revolutionize U.S. air transportation. Air Mobility Pathfinders researchers will evaluate the data from the three separate flight tests to understand the different signal transmission conditions and equipment needed for air taxis and drones to safely operate in the National Air Space. NASA will use the results of this research to design infrastructure to support future air taxi communication, navigation, and surveillance research and to develop new ADS-B-like concepts for uncrewed aircraft systems.

Helicopter Removes Artifact from NASA Armstrong Rooftop

What do the X-15 and the space shuttles have in common? Information from the rocket plane and the spacecraft, as well as many experimental aircraft, were tracked from a pedestal and telemetry dish during key eras in flight history at or near NASA’s Armstrong Flight Research Center in Edwards, California.

When the NASA facility’s administration Building 4800 was built in the 1950s, the infrastructure was included to anchor the rooftop pedestal and dish as the primary way to gather data from aircraft during flights. It was retired in 2015, but a recent roofing project enabled relocation of the artifact to a new place of honor for its support of many experimental aircraft such as the lifting body aircraft, the reverse swept wing X-29, and the highly maneuverable X-31.

“Gathering telemetry data from aircraft on missions is at the core of what we do. Close proximity to the back ramp was one of the big advantages of having the telemetry antenna on the roof in the early days,” said Bob Guere, NASA Armstrong Range Operations chief, referring to the area where aircraft taxi from the hangar to the flightline. “You were able to support ground tests and check airplanes before they taxied without having to use telemetry antennas positioned further away.”

The pedestal, which was prepared for a helicopter lift to remove it from the roof, was used since the 1950s until 2015 to enable different telemetry dishes to collect data from research aircraft.

The rooftop pedestal was key in the early days of the center and its refurbishment in 2003 restored its value. The transformation also included certification to meet Space Shuttle Program landing requirements.

“When a space shuttle deorbited from space it was coming over the top of Edwards,” Guere said. “Telemetry antennas on the hill near NASA Armstrong looked down and with dirt and concrete in the background there were reflections. The rooftop antenna was closer to ground level and looked up as the orbiter was coming in for a landing. It provided an excellent link for shuttle landings.”

The pedestal and dish were not removed when it was decommissioned because of the cost. Now, it’s economical to use a helicopter to remove the pedestal from the roof compared to other options as part of a major project focusing primarily on re-roofing Building 4800. The helicopter lift of the pedestal took a month to plan, plus time to obtain airspace operation and landing permits from the Air Force for the removal project, said Bryan Watters, NASA Armstrong roof project manager.

The pedestal and riser measured 16 feet tall above the rooftop and housed an assembly for the 12-foot dish to rotate. The pedestal and dish together weight about 2,500 pounds and were removed separately. Crews checked the eight bolts anchoring the pedestal and dish to infrastructure on the roof prior to the arrival of a helicopter Oct. 3 before the helicopter arrived.

The following day, after additional briefings, the helicopter was positioned over Building 4800 and a cable was lowered and attached to the pedestal. Once secured, the helicopter slowly gained altitude and took its passenger to the south side of the building. There it was released from the cable and taken to a nearby warehouse for storage. Roofers demolished the steel platform on which the pedestal was located to prepare the area for new roofing materials.

Officials have not determined where the pedestal will be displayed. There are several options to place the pedestal and dish by the famous retired research aircraft on display near the entrance of NASA Armstrong.

NASA Small Business Funding Enables Aircraft Inspection by Drone

A small, black drone with four rotors is shown in the foreground flying in front of a commercial airliner in the background. The airliner is painted white and the front facing windows can be seen behind the drone. Concrete platforms surround the commercial airliner and yellow ramps connect the platforms to the plane.

A small business called Near Earth Autonomy developed a time-saving solution using drones for pre-flight checks of commercial airliners through a NASA Small Business Innovation Research (SBIR) program and a partnership with The Boeing Company.

Before commercial airliners are deemed safe to fly before each trip, a pre-flight inspection must be completed. This process can take up to four hours, and can involve workers climbing around the plane to check for any issues, which can sometimes result in safety mishaps as well as diagnosis errors.

With NASA and Boeing funding to bolster commercial readiness, Near Earth Autonomy developed a drone-enabled solution, under their business unit Proxim, that can fly around a commercial airliner and gather inspection data in less than 30 minutes. The drone can autonomously fly around an aircraft to complete the inspection by following a computer-programmed task card based on the Federal Aviation Administration’s rules for commercial aircraft inspection. The card shows the flight path the drone’s software needs to take, enabling aircraft workers with a new tool to increase safety and efficiency.

“NASA has worked with Near Earth Autonomy on autonomous inspection challenges in multiple domains,” says Danette Allen, NASA senior leader for autonomous systems. 

“We are excited to see this technology spin out to industry to increase efficiencies, safety, and accuracy of the aircraft inspection process for overall public benefit.”

The photos collected from the drone are shared and analyzed remotely, which allows experts in the airline maintenance field to support repair decisions faster from any location. New images can be compared to old images to look for cracks, popped rivets, leaks, and other common issues.

The user can ask the system to create alerts if an area needs to be inspected again or fails an inspection. Near Earth Autonomy estimates that using drones for aircraft inspection can save the airline industry an average of $10,000 per hour of lost earnings during unplanned time on the ground.

Over the last six years, Near Earth Autonomy completed several rounds of test flights with their drone system on Boeing aircraft used by American Airlines and Emirates Airlines.

NASA’s Small Business Innovation Research / Small Business Technology Transfer program, managed by the agency’s Space Technology Mission Directorate, aims to bolster American ingenuity by supporting innovative ideas put forth by small businesses to fulfill NASA and industry needs. These research needs are described in annual SBIR solicitations and target technologies that have significant potential for successful commercialization. 

Small business concerns with 500 or fewer employees, or small businesses partnering with a non-profit research institution such as a university or a research laboratory can apply to participate in the NASA SBIR/STTR program.
