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:
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.

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.
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.

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.
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.

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.

Director of the Aeronautics Division within the agency's Research and Technology Mission Directorate
“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.
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.

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.

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.
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.
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.
In honor of America’s 250th birthday, two of NASA’s most iconic aircraft got a fresh coat of red, white, and blue paint ahead of a flyover in Washington on July 4, 2026, with other NASA aircraft.
An F-15 and an F/A-18 from NASA’s Armstrong Flight Research Center in Edwards, California, recently were repainted in patriotic colors as a tribute to the past and a salute to the future.
The red, white, and blue commemorative paint and Freedom 250 logo will remain on these aircraft for at least the next year, so be sure to catch these at local air shows and events.
Follow along on social media and at https://www.nasa.gov/freedom250/ to learn more about where to spot the aircraft (dependent upon availability and flying schedules):

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.
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.
Pilots, engineers, maintenance techs, project leads, researchers, photographers, and videographers meet to review the flight’s goals, weather reports, and final details.
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.
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.
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.
The pilot communicates with the control tower and taxis to the runway. Control room teams at NASA Armstrong monitor the aircraft via radio.
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.
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.
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.
The pilot, project team, and mission controlstaff return to the briefing room tocapture lessons learned and document items for follow-up.
Teams download flight data for analysis. If two flights are scheduled, preparations begin immediately for the second.
