Cinque giorni, migliaia di chilometri e un’eclissi totale di Sole. La prima nel cuore dell’Europa da ventisette anni. Un’eclissi difficile, di durata relativamente breve – un minuto e mezzo, poco meno o poco più – e per giunta al tramonto. Basta una nuvoletta all’orizzonte a rovinare lo spettacolo.

Sono gli ingredienti di Totalità, un podcast dell’Istituto nazionale di astrofisica ideato e realizzato da Federica Duras e Claudia Mignone – astrofisiche, divulgatrici scientifiche e per l’occasione inviate speciali dalla Spagna per raccontare come si vive, oggi, un’eclissi totale di Sole.

Tutto inizia dalla valigia: cosa portare, a partire dagli occhialini certificati per proteggere la vista (mai osservare a occhio nudo il Sole, intonso o eclissato che sia – l’avrete certamente sentito ripetere più d’una volta negli ultimi giorni), spaziando poi tra macchine fotografiche, filtri, cavalletti e altri strumenti per tentare di immortalare il tanto sospirato evento.

Questo diario di viaggio tutto da ascoltare seguirà le due protagoniste dall’Italia, passando per Valencia, fino all’Aragona, sulle tracce delle antiche spedizioni ottocentesche che dislocavano gli astronomi in giro per il mondo a caccia di qualche minuto di totalità, per cercare di carpire i segreti del stelle partendo da quella a noi più vicina – il Sole. E se tanti misteri cosmici sono ormai stati svelati, molti altri restano ancora irrisolti: è per questo che le eclissi solari continuano a suscitare, ancora oggi, nel 2026, non solo il fascino generale ma anche l’interesse della comunità scientifica. Come quello della spedizione di astrofisici italiani che osserverà il fenomeno il prossimo 12 agosto dall’Observatorio Astrofisico de Javalambre, a duemila metri di quota, nella provincia spagnola di Teruel, per sperimentare un nuovo, ingegnoso strumento per future missioni spaziali.

Tra scienza e storia, consigli per le osservazioni e interviste agli esperti, il podcast esplora le molteplici sfaccettature di un avvenimento tra i più travolgenti che il cielo può regalare a noi, piccoli abitanti del terzo pianeta in orbita attorno al Sole. Con le emozioni della narrazione dal vivo, gli imprevisti del viaggio, le sfide della ricerca e l’incognita – onnipresente, imperante e contro la quale ogni scongiuro è vano – del meteo: la cronaca, insomma, di un’eclissi (quasi) impossibile.

Potete ascoltare Totalità su Apple Podcast, su Spotify e su YouTube, oltre che sulla piattaforma di Media Inaf dedicata ai podcast, a partire da oggi, domenica 9 agosto. E poi ogni giorno, fino al 13 agosto. Per scoprire se le protagoniste saranno riuscite nell’intento di contemplare la loro prima eclissi totale di Sole.

The International Space Station hosts hundreds of science experiments at a time. Some experiments can take hours to perform, and researchers need to account for astronauts’ limited time. Fully automated devices, like Redwire’s  ADvanced Space Experiment Processors (ADSEPs), have been designed to conduct more space science with less crew time.

Within each ADSEP facility there are three to four “mini-laboratories”, called cassettes, that allow multiple studies with different needs to be performed at the same time. The latest model, ADSEP-4 can accommodate four cassettes and features imagery capabilities. Since 2017, ADSEPs have conducted and supported two dozen investigations aboard space station with new ones on the horizon.

The latest ADSEP investigations are related to growing seed crystals in space, which can be used to reformulate existing drugs or develop entirely new therapeutics. Previous experiments have shown that the unique microgravity environment allows the growth of larger and higher quality crystals. With Redwire’s Pharmaceutical In-Space Laboratory (PIL-BOX), a cassette-based system that uses the ADSEP facility, researchers can grow improved, space-grown seed crystals.

Notable PIL-BOX experiments sponsored by the ISS National Laboratory have focused on cancer research. The ADSEP-PIL-10 investigation, currently being conducted in orbit in collaboration with the Aspera Biomedicines, works to crystallize cancer-blocking and cancer-promoting molecules with the goal of creating an oral cancer medication. ADSEP-PIL-15 crystalized cancer-treating medicines to help refine production, quality, and stability of these cancer drugs. A recent technology demonstration, ADSEP- ICC (Industrial Crystallization Cassette), tested a larger cassette to expand ADSEP function and scale crystallization production for commercial use.

ADSEPs are not limited to crystal growth and can also be used for culturing cells and tissues, studying organisms, and researching materials-sciences. In 2021, ADSEP-UMAMI studied how bobtail squid interacted with beneficial microbes in the space environment. This research found that symbiotic interactions with microbes can lessen a host animal’s stress responses caused by spaceflight and accelerate developmental pathways such as growing neurons and tissues. These findings give insight into the importance of symbiotic relationships in closed ecosystems like spacecraft and have implications for astronauts and their own beneficial bacteria during space missions.

The automation and versatility of ADSEPs permit a wide array of science experiments to be conducted aboard the orbiting laboratory, leading to findings that inform future space missions and are beneficial to people on Earth.

NASA opened its newest wind tunnel, the Flight Dynamics Research Facility at NASA’s Langley Research Center in Hampton, Virginia, on Friday, providing a critical resource for the agency and its partners to test the safety and performance of future generations of aircraft, rockets, and space exploration vehicles.

NASA opened its newest wind tunnel, the Flight Dynamics Research Facility, Friday, providing a critical resource for the agency and its partners to test the safety and performance of future generations of aircraft, rockets, and space exploration vehicles.

Located at NASA’s Langley Research Center in Hampton, Virginia, the Flight Dynamics Research Facility will support advances in aircraft safety, X‑plane development, drone research, and spacecraft technology. The facility will enable both free‑flight and mounted testing of a wide range of scale-model vehicles designed to travel through an atmosphere, from airplanes to space capsules returning to Earth.

“The Flight Dynamics Research Facility is NASA’s first major new wind tunnel in more than 40 years and gives us a powerful new platform to test the ideas and technologies that will shape the future of aviation and exploration,” said NASA Administrator Jared Isaacman. “America has led in air and space because we were willing to take on hard problems, challenge assumptions, and build what didn’t exist before. This facility gives the talented team at Langley, and our partners across government, industry, and universities, the tools to keep pushing the boundaries of what’s possible and ensure America remains the world leader in air and space.”

A ribbon-cutting ceremony at NASA Langley marked the start of a new chapter in flight research. Agency leaders, partners, and Virginia officials emphasized how the Flight Dynamics Research Facility’s state-of-the-art capabilities will shape the future of flight and exploration.

“The opening of the Flight Dynamics Research Facility represents a significant advancement for NASA and for the nation,” said Dr. Trina Dyal, NASA Langley center director. “By bringing modernized testing capabilities under one roof, we are enabling transformative research that will ensure the United States remains at the forefront of aeronautics and exploration.”

Built through a partnership with the U.S. General Services Administration (GSA), the facility replaces aging infrastructure with an energy-efficient facility that reduces maintenance costs and provides the flexibility needed for future research. The Flight Dynamics Research Facility is part of a broader, long-term collaboration between the agencies, representing the fourth new building GSA has delivered to NASA under Langley’s 20-year campus revitalization plan.

“GSA is proud to partner with NASA in delivering the Flight Dynamics Research Facility, a state-of-the-art asset that will power the next generation of American dominance in aeronautics and space exploration,” said Edward C. Forst, GSA administrator. “This facility reflects what we do best: provide the advanced, expertly designed installations that federal agencies need to carry out their missions. With these new capabilities, NASA will be better equipped to test bold ideas, validate new designs, and advance technologies that will serve the nation for decades to come.”

The Flight Dynamics Research Facility combines and improves upon the capabilities of two historic NASA Langley wind tunnels – the 20-Foot Vertical Spin Tunnel and the 12-Foot Low-Speed Tunnel. The 25,000-square-foot building features a vertical wind tunnel with improved airflow, modern digital systems, and flexible testing capabilities that will allow researchers to study how aircraft, spacecraft, parachutes, and other vehicles behave during flight.

The facility’s 20-foot diameter test chamber is much larger than those of its NASA Langley predecessors, allowing for more air to pass around test models and improving data accuracy. Its increased size also allows for the use of larger, more detailed models during testing.

The Flight Dynamics Research Facility’s top airspeed of 117 miles per hour is twice as fast as the old  facilities, enabling free-flight tests of heavier scale models. This will allow simulations of full-scale vehicles flying at higher altitudes – a critical capability for operations such as studying the stability of aircraft or reentry capsules coming back from space.

The facility’s wind power comes from four 750-horsepower motors, each with an integrated, 14-foot diameter, eight-bladed fan. The fan blades are made of lightweight carbon fiber, enabling rapid, precise airspeed adjustments during free‑flight tests.

The Flight Dynamics Research Facility illustrates the powerful synergy between NASA’s aeronautics and space exploration efforts, with each driving innovation in the other. The facility will drive experimental research across a wide range of flight systems, advancing the development of autonomous flight vehicles, drones, commercial and military aircraft, and X‑planes.

As NASA prepares for a sustained human presence on the lunar surface through the Artemis program and the development of a Moon Base, the facility will play a key role in testing vehicle designs for entry, descent, and landing that will help reduce mission risk and support the safe return of crews to Earth. NASA also will be able to use the wind tunnel  to help design aircraft for Mars and other destinations in our solar system where atmospheric flight is possible.

With the Flight Dynamics Research Facility now open, NASA is entering a new era in flight research – one that will shape the aircraft and spacecraft of tomorrow, strengthen industry partnerships, and extend the agency’s legacy of pioneering aerospace leadership.

The facility is managed under the Aerosciences Evaluation and Test Capabilities portfolio in the Aeronautics Division of NASA’s Research and Technology Mission Directorate.

Concluding an eight-month science mission aboard the International Space Station, NASA astronaut Chris Williams returned to Earth on Sunday alongside Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev.

The crew made its safe, parachute-assisted landing at 5:27 a.m. CDT (3:27 p.m., Kazakhstan time), southeast of Dzhezkazgan, after departing the space station at 2:03 a.m., aboard the Soyuz MS-28 spacecraft.

The crew was in space for 241 days, orbiting the Earth 3,856 times and traveling more than 102 million miles. They launched to the International Space Station on Nov. 27, 2025. The mission was the first for Williams and Mikaev and the second for Kud-Sverchkov.

While aboard the orbiting laboratory, Williams supported a wide range of scientific investigations and technology demonstrations. He helped advance research for new cancer treatments and improved in-space manufacturing of materials used in high-performance computers and electronics. Williams also completed two spacewalks to prep for space station power system upgrades and to replace a faulty joint on the Canadarm2 robotic arm. The crew’s work aboard the space station helps improve life on Earth and prepare for future human missions to the Moon and Mars.

Following post-landing medical checks, the crew members will fly by helicopter to Karaganda, Kazakhstan, where recovery teams are based. Williams then will board a NASA aircraft bound for the agency’s Johnson Space Center in Houston.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

After eight months aboard the International Space Station for his first mission, NASA astronaut Chris Williams is preparing to return to Earth. During his assignment, Williams contributed to research for new cancer treatments, advanced the production of materials to improve computers and electronics, ventured into the vacuum of space to complete two spacewalks, and much more. Williams’ work aboard the space station helped to improve life on Earth and prepare for future missions to the Moon and Mars.

Here are some of the research highlights from his mission:

Cancer-fighting constructs

NASA astronaut Chris Williams and ESA (European Space Agency) astronaut Sophie Adenot work to process DNA-inspired materials that could advance new cancer treatments for people on Earth. In space, these rod-shaped materials form more evenly and consistently, which may improve their performance and readiness for treatments on Earth. While there have been major advancements in cancer therapies, many treatments can affect the whole body and cause side effects without fully treating solid tumors. This research aims to enable targeted cancer therapies that reach deep into tumors, stay in the body longer, and release medicine in a more controlled way.

Superior semiconductors

NASA astronaut Chris Williams conducts research to grow semiconductor crystals in space. In microgravity, researchers can grow more crystals of the desired size than can be produced on Earth. Previous research shows that space-grown crystals can offer increased performance to help advance technologies like high-performance computers, artificial intelligence, and medical devices. This research lays the groundwork for commercial semiconductor manufacturing in space and advances the semiconductor industry.

Eyeing Earth

NASA astronaut Chris Williams looks out of a cupola window at a red aurora glowing above the Earth. Since the 1960s, astronauts have photographed Earth from space to help scientists monitor the planet’s changing landscapes, natural disasters, and other features over time. Along the way, astronauts also have captured images of celestial objects such as comets, auroras, and the Milky Way.

Sub-zero medical samples

NASA astronaut Chris Williams works with a special freezer aboard the International Space Station that keeps research samples at ultra-cold temperatures until they can return to Earth. Throughout each mission, astronauts collect biological samples like blood and urine to help scientists understand how long-duration spaceflight affects the human body. Observing crew members during their space missions and studying these frozen samples back on Earth helps NASA protect astronaut health during future missions to the Moon, Mars, and beyond.

Capturing cargo

NASA astronauts Jack Hathaway and Chris Williams watch from the cupola windows as Northrop Grumman’s Cygnus XL cargo spacecraft approaches the International Space Station. The two played key roles in the capture of the spacecraft, which delivered approximately 11,000 pounds of supplies, including fresh food, life support equipment, and scientific research as part of NASA’s Northrop Grumman Commercial Resupply Services 24 mission. Cargo missions help keep the space station operating and provide astronauts with the supplies they need to live, work, and conduct research in orbit.

Blocking biofilms

NASA astronaut Chris Williams works on an investigation that tests the use of ultraviolet light to help prevent the formation of microbial colonies, called biofilms. Biofilms can clog and contaminate water systems, damage equipment, and pose health risks to astronauts. This research aims to keep surfaces cleaner and safeguard systems during long-duration space missions. Using UV light for sanitation also could reduce the need for chemical disinfectants in space, decreasing the risk of chemical exposure and eliminating difficulties in transporting or storing supplies.

Strengthening solar power

NASA astronaut Chris Williams ventured outside the International Space Station for two spacewalks during his mission. In June, he helped make repairs to Canadarm2, a robotic arm that captures cargo spacecraft and deploys external research. In March, Williams prepared the orbiting laboratory for new solar arrays to be added to the station in a future spacewalk. Once installed, the final set of International Space Station Roll Out Solar Arrays (IROSA) will complete the full suite of additional solar power, increasing the station’s power generation by about 30% and enhancing support for scientific research and daily operations. The same solar array technology also powered NASA’s Double Asteroid Redirection Test and could support future missions to the Moon and Mars.

Learn more about the space station’s IROSAs.

Microgravity medicine

NASA astronaut Chris Williams works with hardware to support the development of new cancer and disease treatments by studying the growth of protein crystals for pharmaceuticals. In space, protein crystals form higher-quality structures than they do on Earth, allowing researchers to better understand how to target and treat disease. Here, Williams works with a project that aims to develop a new formula for a cancer treatment that could be taken orally. Growing protein crystals in space paves the way for more commercial companies to create new therapies that could improve patient outcomes on Earth.

Robotic refinement

NASA astronaut Chris Williams works with equipment that tests the performance of small robotic arms in space. Some experiments and operations require very precise movements, where tiny errors can significantly impact results. Understanding how microgravity affects delicate robotic operations helps researchers improve designs for future automated systems that can perform operations while astronauts focus on the most critical tasks.

Messier 94 is a spiral galaxy with a bright inner ring around it, called a starburst ring, where new stars are forming.

This composite of images taken by NASA’s Psyche mission shows the crescent of Mars grow as the spacecraft approached the planet for a gravity assist from May 2 to May 15, 2026. Because Psyche approached Mars from a high phase angle, the planet appeared as a thin crescent in the days running up to the close approach, lit by sunlight reflecting off its surface.

An aircraft powered by a megawatt-class hybrid-electric engine developed in collaboration with NASA and built by GE Aerospace, demonstrated flight of an innovation that can inform new generations of fuel-saving aircraft power systems.

Mounted to a Saab 340B aircraft, the engine flew at Farnborough International Air Show in the United Kingdom. It was the public debut of a system that has in recent months made historic test flights, becoming the first hybrid electric-powered aircraft to fly above 30,000 feet.

“This achievement reflects what NASA does best in aeronautics: we explore bold possibilities, validate them through rigorous research and testing, and work with industry to turn breakthrough ideas into technologies that bring real value for the American people,” said Laurie Grindle, director of the Aeronautics Division within the agency’s Research and Technology Mission Directorate at NASA Headquarters in Washington.

The testing leveraged work done through NASA’s former Electrified Powertrain Flight Demonstration project and the agency’s ongoing Subsonic Vehicle Technologies and Tools project – years of collaborative research that included key testing at NASA test facilities. 

The engine integrates electric motors, a gas turbine, and energy storage capabilities. It was designed to demonstrate the capacity to power an aircraft around the size of a regional-class jet, reducing fuel burn and costs without sacrificing performance. The unit’s technology and designs are expected to be used to help develop future hybrid systems that could lower airline operating costs. 

The demonstration flight came after years of rapid development for the technology. For NASA, it also validates work that stretches back to a time when hybrid aviation propulsion seemed almost beyond the horizon of possibility.

“This is the culmination of more than 15 years of work, and we did that because it’s going to have an impact for aircraft that will help reduce energy use and help U.S. companies and the public,” said Ralph Jansen, aerospace engineer at NASA’s Glenn Research Center in Cleveland. “It’s about having a vision that no one believes can happen and then doing the work to define and execute the research and development needed to make it happen.”  

This accomplishment was possible because of the collaborative effort of hundreds of people working on Electrified Powertrain Flight Demonstration and Subsonic Vehicle Technologies and Tools projects across NASA centers, in conjunction with GE Aerospace and its partner companies.

Hybird-Electric Evolves

In recent years, aviation has seen a boom in small aircraft and drones powered by electrical systems drawing from batteries. But large passenger and cargo planes require complex engines capable of supplying massive amounts of power. So more than a decade ago when NASA began contemplating hybrid systems, just the possibility of using electric motors to supplement some energy was a daunting engineering challenge. 

NASA spent about seven years performing preliminary research, working with small businesses and other partners to consider technological obstacles and the potential commercial viability of hybrid systems. During that time, the agency addressed several barriers to implementation including the power, thermal, and battery technology, and the integration of the power system, engine, and aircraft.

Through the agency’s Electrified Powertrain Flight Demonstration award, GE Aerospace and NASA worked with researchers to develop lighter and more efficient power systems and shrink key components – sometimes dramatically. 

NASA and GE Aerospace also leveraged agency facilities and resources to further their research. In 2022, GE Aerospace tested an integrated version of its propulsion system at NASA’s Electric Aircraft Testbed at the agency’s Neil A. Armstrong Test Facility in Sandusky, Ohio. Testing allowed the system to operate in conditions simulating 45,000 feet in altitude, the range in which commercial single-aisle aircraft fly. 

The team added components, including electric motors, power converters, propellers, and a GE Aerospace commercial engine, followed by more ground tests and eventual flight tests. For the researchers who’d spent years on the concept, seeing the engine powering an aircraft in flight was a major step in a long journey.

“I’ve got to say, I was pretty touched seeing it fly. It was just awesome,” Jansen said.  “It’s just like a regular plane, which is probably the best thing of all.”

NASA’s current support for this research is through the Aeronautics Division of its Research and Technology Mission Directorate.

On the morning of July 20, 1976, roughly 40 minutes after mission controllers received word that the Viking 1 lander had successfully touched down on the surface of Mars, this photo gave us our first view from the surface of the Red Planet.

NASA researchers recently put a new wing design, appearing long and thin with a lightweight structural design, through a series of grueling tests to find its structural limits. What they found left them encouraged about the wing’s potential, even when they pushed it past its intended limits.

The 15-foot Structural Wing Experiment Evaluating Truss-bracing (SWEET-15) test article is part of NASA’s research to develop future ultra-efficient aircraft. The design incorporates a long wing supported by an aerodynamic strut, based on NASA’s earlier Transonic Truss‑Braced Wing concept.

The research team is working to understand whether SWEET-15’s design and its new lightweight structural designs could help commercial airliners save fuel. But first, they need to understand how it behaves under the kinds of force wings experience in flight.

The SWEET-15 design originated with combining five different advanced composite manufacturing and assembly technologies that enabled the novel structural design. The 15-foot-long test article was then designed and fabricated at NASA’s Langley Research Center in Hampton, Virginia, before traveling to NASA’s Armstrong Flight Research Center in Edwards, California, for testing.

Over several months, NASA engineers intentionally bent the test wing in the Flight Loads Laboratory at NASA Armstrong. Numerous strain and load sensors, including fiber-optic strain sensors, were placed throughout the structure to track how the wing responded as forces increased.

The data from the sensors confirmed the predictions made by NASA’s computer models. According to initial findings, the wing withstood the anticipated in-flight forces without issue. The results provided the team with confidence in the new manufacturing approaches and methods for connecting wing parts used in SWEET-15, which could support future efficient aircraft designs. The manufacturing approach, developed at NASA Langley used the Integrated Structural Assembly of Advanced Composites robot, aims to produce lighter and stronger composite structures for aerospace vehicles.

The test concluded with a deliberate test-to-failure, where engineers increased loads beyond the wing’s design limits to determine how and where it would fail. The structure ultimately failed at roughly 127% of its design limit load, with visible damage appearing near the back edge of the wing and in the upper wing cover. This element of testing provided valuable insight into how the joints connecting the wing to its main strut and a secondary one, called a jury strut, behave under forces beyond the expected flight envelope.

This marks the first time a representative composite truss-braced wing configuration has undergone this type of structural evaluation.  It was made possible only through NASA collaboration across centers and projects, with researchers utilizing agency resources such as the Fiber Optic Sensing System developed to gather data on both aircraft and spacecraft.

To prepare for the testing, engineers at NASA Langley designed, analyzed, and manufactured the wing and completed safety preparations and lab setup.

Researchers will now analyze the data collected during testing to inform future airframe designs and support NASA’s ongoing efforts to develop more efficient aviation technologies.

The work is being conducted through NASA’s Subsonic Flight Demonstrator project in the agency’s Research Technology Mission Directorate. The successful testing of multiple innovative components marks a milestone in NASA’s aeronautics research.

Scientists using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) directly measured the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the “Lighthouse” Nebula, for the first time.

In the Picture of the Month from the James Webb Space Telescope, we are taken on a visit to a building site of significant scale. The project is a galaxy cluster named MACS J0553.4-3342, located in the constellation Columba (the Dove).

Testing new aerospace concepts in flight remains one of NASA’s most effective ways to advance knowledge and reduce risk.

The Dale Reed Subscale Flight Research Laboratory at NASA’s Armstrong Flight Research Center in Edwards, California, supports this mission by using small, remotely piloted and autonomous aircraft as cost‑effective platforms to mature innovative ideas, accelerate learning, and enable smoother transitions to full‑scale flight.

When experiments require a flight platform, several NASA remotely piloted aircraft are available: the Alta‑X quadrotor; the Dryden Remotely Operated Integrated Drone (DROID) with its 10‑foot wingspan; and the Multi‑Use Cub, a 14‑foot‑span fixed‑wing aircraft with an expandable payload capacity for flight experiments. For electric vertical takeoff and landing testing, the HQ‑90 quadrotor provides an additional option.

Once aircraft and experiments are cleared for operations, laboratory pilots support the mission, including ground operations and flight activities.

Flight expertise

Each staff member serves as an experienced and certified subscale aircraft pilot and is prepared to fly unique one-of-a-kind or modified commercial aircraft wherever the mission requires.

NASA’s FireSense project conducted flights in the Geneva State Forest, located about 100 miles south of Montgomery, Alabama. NASA Armstrong flight research staff integrated the instrument onto an Alta-X drone and tested the system before deployment. Two team members then transported the drone and sensor to the forest, prepared the vehicle for flight, and operated it during the mission. The NASA sensor was flown on the drone to demonstrate how remotely piloted aircraft can gather localized weather data that influences smoke movement and fire behavior. This information may help operational agencies improve wildfire decision-making and better allocate firefighters and resources.

Other missions occur closer to NASA Armstrong, such as the Enhancing Parachutes by Instrumenting the Canopy (EPIC) project. EPIC involved air‑launching a capsule containing a parachute and flexible sensor from the Alta‑X. Laboratory staff piloted the flights, supported flight operations, and worked with the EPIC team to design and integrate the parachute‑drop mechanism and safety system into the aircraft.

These tests demonstrated that a flexible sensor could help researchers study supersonic parachutes. Continuation of this work can help fill gaps in computer models, making supersonic parachutes safer and more reliable for delivering science instruments and payloads to Mars.

Advancing challenging research

The Dale Reed Subscale Flight Research Laboratory uses rapid design and testing capabilities to help small aircraft fly big ideas. These concepts could lead to future breakthroughs that support NASA’s missions across aeronautics, science, and exploration.

For decades, NASA and its partners have advanced Automatic Collision Avoidance Technology. The research demonstrated an autopilot could detect and recover from an imminent ground collision – a capability now helping save lives in high‑performance U.S. military jets. NASA Armstrong had key roles in that work and developed a simplified version, the Automatic Ground Collision Avoidance System, which was installed on the DROID for testing.

The system demonstrated on the DROID — developed to assist general aviation pilots as well as remotely piloted and autonomous aircraft — performed well and led to further research toward a version that provides alerts and steering cues. The NASA Armstrong Technology Transfer Office is working to license the technology for U.S. businesses to develop the system as a commercial product.

The Prandtl‑D (Preliminary Research Aerodynamic Design to Lower Drag) flying‑wing glider was also designed, fabricated, and flown at NASA Armstrong. Researchers found that its twisted wing design could reduce drag and generate thrust at the wingtips, advancing concepts that may support greater fuel economy for future aircraft. The original Prandtl‑D is now part of the Smithsonian National Air and Space Museum collection in Washington, and the Prandtl-D3 is at the California Science Center in Los Angeles. Researchers continue developing the next generation of the design in the laboratory.

A wide range of capabilities in the laboratory help transform promising concepts into flight-ready test structures. These include rapid prototyping using traditional and advanced 3D manufacturing techniques, as well as composite and conventional fabrication processes. The team of engineers and technicians also provides custom component design and specialized fabrication to meet unique research needs.

The laboratory supports electrical and mechanical design, hardware and software integration, and the safety and flight-readiness processes required for successful missions. Additional technical facilities, such as the Experimental Fabrication Branch and the Environmental Laboratory at NASA Armstrong, further enhance these capabilities. Together, they support development, testing, and validation activities that advance NASA’s aeronautics and exploration goals.

No one wants to get into an uncomfortable aircraft. NASA research could help the emerging industry of air taxis —small, vertical-takeoff-and-landing aircraft meant for short trips — understand the relationship between comfort and willingness to fly.

That’s where NASA comes in, with data that can help identify how to plan air taxi rides that can keep travelers feeling good.

NASA was able to gather that data by putting its own employees through some rough virtual flights. At the agency’s Armstrong Flight Research Center in Edwards, California, volunteers have been strapping into a virtual reality motion simulator to experience the sudden shifts and tilts that tomorrow’s air taxis could encounter, showing researchers those moments feel from a passenger’s point of view.

Their reactions are giving NASA new insight into how aircraft motion influences comfort and confidence in flight — for instance, that certain kinds of large, sudden motions can be especially bothersome. Using that data, the team developed new models linking those sudden motions to passengers’ willingness to fly. The models can help guide future aircraft design and flight operations, letting producers know what maneuvers will be too jarring for future air taxi riders.

Large, sudden movements can also come from gusting winds or landings. The NASA data allows researchers to estimate when passengers may begin to feel uncomfortable as motion increases, giving them the ability to shape aircraft designs and operations to minimize the impact of those situations.

“Through this study and others, we are starting to identify passenger comfort thresholds for aggressive flight motion,” said Curtis Hanson, NASA Armstrong lead researcher for this effort. “We can begin to make predictions about how air taxis should fly so that most passengers will find the experience enjoyable and want to ride again, which will benefit the public and the industry.”

In the simulator, each participant experienced four levels of their aircraft pitching up and down, tilting from side-to-side, rotating, or accelerating quickly into a climb or a dive during flights from downtown San Francisco to Alcatraz Island in California. Even moderate changes in these motions reduced comfort for some participants, while others remained comfortable at higher levels. Participants rated each flight on a five-point scale and identified which motions felt uncomfortable.

Participants were asked whether they would take a real air taxi flight with motion they find uncomfortable. Their answers suggested that today’s travelers may be less tolerant of rough motion than airline passengers 50 years ago, based on comparisons with earlier NASA ride-quality research.

This latest feedback builds on a multiyear NASA study to better understand air taxi passenger comfort. The overall research effort found clear relationships between specific aircraft motions and how comfortable people feel during flight.

This work is currently led under the Subsonic Vehicle Technologies and Tools project in NASA’s Research and Technology Mission Directorate and contributes to the agency’s advanced air mobility research.

NASA flight photographers capture history from a perspective few ever experience, getting a rare bird’s-eye view of the agency’s missions in action. Their photos document key NASA research and give the public a front-row seat to the work happening behind the scenes.

Jim Ross, a photographer at NASA’s Armstrong Flight Research Center in Edwards, California, flew over Washington during the Fourth of July celebration to document a NASA flyover commemorating America’s 250th birthday. He’s captured some of the agency’s most exhilarating milestones, like early SR-71 flights, the delivery flight of Space Shuttle Endeavour to Los Angeles, and first flights of NASA’s X-59 quiet supersonic research aircraft.

“I grew up in Bozeman, Montana, when it was still considered a small town, so if someone told that little kid that he would be flying in a F-18 over the National Mall, he would have never believed it,” Ross said. “I love documenting history, and having the opportunity to capture flights and launches has kept me doing it for almost 37 years.”

Ross began his aviation photography career in 1989 when he joined the staff at NASA Armstrong (then Dryden). He became the photo lead in 1997, a title he retains.

Flight testing is a team sport. For nearly 80 years, teams at NASA’s Armstrong Flight Research Center in Edwards, California, have used flight testing to push the limits of aerodynamics and advance aviation.

Earlier this year, NASA’s Crossflow Attenuated Natural Laminar Flow (CATNLF) initiative tested a wing concept that would maximize the smooth flow of air known as laminar flow, which could lower fuel costs for future airliners. During flight testing, researchers strapped a scale-model CATNLF wing to the bottom of a NASA F-15 aircraft.

Here’s what a day of CATNLF flight testing looked like.

5 a.m. — Aircraft staging

Ground crews ready the aircraft for the mission. If the operation involves a chase plane — a second aircraft to monitor the test flight — it would also be prepared, along with its crew.  

6 a.m. — Crew brief

Pilots, engineers, maintenance techs, project leads, researchers, photographers, and videographers meet to review the flight’s goals, weather reports, and final details.

6:30 a.m. — Control room checks, air crew suit-up

Researchers head to the control room to complete day-of checks, confirming all communications, displays, and instruments are functioning.

Pilots suit up in life support, including custom‑fit pressure suits, harnesses, helmets, and masks. If a photographer, videographer, or flight test engineer will be in the aircraft’s back seat, they do the same.

6:45 a.m. — Air crew steps, control room preparations

The pilot completes preflight checks with the crew chief and technicians for the aircraft’s electrical systems. The pilot and the crew chief sign a flight preparedness report confirming the aircraft is ready to fly.

Inside the control room, the team prepares to monitor the flight using the same set of test cards, a step-by-step plan for the flight.

7 a.m. — Pilot secured in jet

The pilot and backseat crew member climb into their seats, strap in, and secure any gear they’ve brought for the test. The pilot completes preflight ground checks.

7:15 a.m. — Aircraft taxi

The pilot communicates with the control tower and taxis to the runway. Control room teams at NASA Armstrong monitor the aircraft via radio.

7:30 a.m. — Takeoff

The pilot accelerates down the runway and, at the proper speed, pulls back on the stick to take off. Once airborne, the pilot coordinates with air traffic control at Edwards Air Force Base and the NASA Armstrong control room while flying to the designated test area.

7:30 to 8:30 a.m. — Flight

At the test location, the team coordinates with the pilot on altitude, speed, and maneuvers. The test conductor relays each task, and the pilot completes them one-by-one. The pilot and control room monitor the performance of the hardware, instruments, aircraft, or software throughout the sequence. After completing the test points, the pilot returns to base.

8:45 a.m. — Landing, towing

The pilot lands and taxis to the ramp at NASA Armstrong, where the crew chief meets the jet. After the pilot exits, the aircraft is towed into the hangar for maintenance.

9:30 a.m. — Crew debrief

The pilot, project team, and mission controlstaff return to the briefing room tocapture lessons learned and document items for follow-up.

10 a.m. — Data download, second flight prep

Teams download flight data for analysis. If two flights are scheduled, preparations begin immediately for the second.
