  • 2025 in Review: Highlights from NASA in Silicon Valley 

    NASA’s Ames Research Center in California’s Silicon Valley continued to make strides in research, technology, engineering, science, and innovation this past year. Join us as we take a look back at some of the highlights from 2025.

    From Supercomputers to Wind Tunnels: NASA’s Road to Artemis II

    This video shows two simulations of the SLS (Space Launch System) rocket using NASA’s Launch Ascent and Vehicle Aerodynamics solver. For the Artemis II test flight, a pair of six-foot-long strakes will be added to the core stage of SLS that will smooth vibrations induced by airflow during ascent. The top simulation is without strakes while the bottom shows the airflow with strakes. The green and yellow colors on the rocket’s surface show how the airflow scrapes against the rocket’s skin. The white and gray areas show changes in air density between the boosters and core stage, with the brightest regions marking shock waves. The strakes reduce vibrations and improves the safety of the integrated vehicle.

    By combining the technologies of the NASA Advanced Supercomputing facility and Unitary Plan Wind Tunnel at NASA Ames, researchers were able to simulate and model an adjustment to the Space Launch System (SLS) rocket that could improve airflow and stability to the vehicle during the launch of Artemis II. The collaborative effort between researchers is the next step on NASA’s journey to send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

    New Discoveries in Early Solar System Samples

    A microscopic particle of asteroid Bennu, brought to Earth by NASA’s OSIRIS-REx mission, is manipulated under a transmission electron microscope. In order to move the fragment for further analysis, researchers first reinforced it with thin strips of platinum (the “L” shape on the particle’s surface) then welded a tungsten microneedle to it. The asteroid fragment measures 30 micrometers (about one-one thousandth of an inch) across.
    NASA

    Researchers at NASA Ames discovered a never-before-seen “gum-like” material in pristine asteroid samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft. The surprising substance was likely formed in the early days of the solar system, as Bennu’s young parent asteroid warmed. Such complex molecules could have provided some of the chemical precursors that helped trigger life on Earth, and finding them in the pristine samples from Bennu is important for scientists studying how life began and whether it exists beyond our planet.

    Curiosity Mars Rover Uncovers Subsurface Clues to the Planet’s Evolution

    An image of Mars shows rocks and small sand dunes, with a larger mountain range in the background. Two wheel tracks in the foreground show Curiosity rover's path before it captured the image.
    NASA’s Curiosity Mars rover sees its tracks receding into the distance at a site nicknamed “Ubajara” on April 30, 2023. This site is where Curiosity made the discovery of siderite, a mineral that may help explain the fate of the planet’s thicker ancient atmosphere.
    NASA/JPL-Caltech/MSSS

    NASA’s Curiosity Mars rover helped shed new light on what happened to the planet’s ancient atmosphere. Researchers have long believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on the planet’s surface. That carbon dioxide and water should have reacted with Martian rocks to create carbonate minerals, but previous investigations haven’t found expected amounts of carbonate on the planet’s surface. Curiosity used onboard instruments to study powdered Martian rock samples from the subsurface of the planet, finding the presence of siderite, an iron carbonate mineral, within the sulfate-rich rocky layers of Mount Sharp in Mars’ Gale Crater.

    With a second Trump Administration at the helm in 2025, NASA marked significant progress toward the Artemis II test flight early next year, which is the first crewed mission around the Moon in more than 50 years, as well as built upon its momentum toward a human return to the lunar surface in preparation to send the first astronauts — Americans — to Mars.

    As part of the agency’s Golden Age of innovation and exploration, NASA and its partners landed two robotic science missions on the Moon; garnered more signatories for the Artemis Accords with 59 nations now agreeing to safe, transparent, and responsible lunar exploration; as well as advanced a variety of medical and technological experiments for long-duration space missions like hand-held X-ray equipment and navigation capabilities.

    NASA also led a variety of science discoveries, including launching a joint satellite mission with India to regularly monitor Earth’s land and ice-covered surfaces, as well as identifying and tracking the third interstellar object in our solar system; achieved 25 continuous years of human presence aboard the International Space Station; and, for the first time, flew a test flight of the agency’s X-59 supersonic plane that will help revolutionize air travel.

    Sean Duffy, named by President Trump, is serving as the acting administrator while NASA awaits confirmation of Jared Isaacman to lead the agency. Isaacman’s nomination hearing took place in early December, and his nomination was passed out of committee with bipartisan support. The full Senate will consider Isaacman’s nomination soon. President Trump also nominated Matt Anderson to serve as deputy administrator, and Greg Autry to serve as chief financial officer, both of whom are awaiting confirmation hearings. NASA named Amit Kshatriya to associate administrator, the agency’s highest-ranking civil servant position.

    Key accomplishments by NASA in 2025 include:

    Astronauts exploring Moon, Mars is on horizon

    Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build upon our foundation for the first crewed mission to Mars. The Artemis II test flight is the first flight with crew under NASA’s Artemis campaign and is slated to launch in early 2026. The mission will help confirm systems and hardware for future lunar missions, including Artemis III’s astronaut lunar landing.

    NASA also introduced 10 new astronaut candidates in September, selected from more than 8,000 applicants. The class is undertaking nearly two years of training for future missions to low Earth orbit, the Moon, and Mars. 

    Progress to send the first crews around the Moon and on the lunar surface under Artemis includes:

    • NASA completed stacking of its Space Launch System rocket and Orion spacecraft for Artemis II. Teams integrated elements manufactured across the country at NASA’s Kennedy Space Center in Florida, including the rocket’s boosters and core stage, as well as Orion’s stage adapter and launch abort system, to name a few.
    • Ahead of America’s 250th birthday next year, the SLS rocket’s twin-pair of solid rocket boosters showcases the America 250 emblem.
    • The Artemis II crew participated in more than 30 mission simulations alongside teams on the ground, ensuring the crew and launch, flight, and recovery teams are prepared for any situation that may arise during the test flight. Soon, crew will don their survival suits and get strapped into Orion during a countdown demonstration test, serving as a dress rehearsal for launch day.
    • The agency worked with the Department of War to conduct a week-long underway recovery test in preparation to safely collect the Artemis II astronauts after they splashdown following their mission.
    • To support later missions, teams conducted a booster firing test for future rocket generations, verified new RS-25 engines, test-fired a new hybrid rocket motor to help engineering teams better understand the physics of rocket exhaust and lunar landers, as well using various mockups to test landing capabilities in various lighting conditions. Teams also conducted human-in-the-loop testing in Japan with JAXA (Japan Aerospace Exploration Agency) with a rover mockup from their agency.
    • NASA also continued work with Axiom Space, to develop and test the company’s spacesuit, including completing a test run at the Neutral Buoyancy Laboratory at NASA Johnson ahead of using the suit for Artemis training. The spacesuit will be worn by Artemis astronauts during the Artemis III mission to the lunar South Pole.
    • On the Moon, future crew will use a lunar terrain vehicle, or LTV, to travel away from their landing zone. NASA previously awarded three companies feasibility studies for developing LTV, followed by a request for proposals earlier this year. The agency is expected to make an award soon to develop, deliver, and demonstrate LTV on the lunar surface later this decade. The agency also selected two science instruments that will be included on the LTV to study the Moon’s surface composition and scout for potential resources.
    • For operations around the Moon, NASA and its partners continued to develop Gateway to support missions between lunar orbit and the Moon’s surface. Construction and production of the first two elements, a power and propulsion system and habitation element, each progressed, as did development and testing of potential science and technology demonstrations operated from Gateway. International partners also continued work that may contribute technology to support those elements, as well as additional habitation capabilities and an airlock.
    • This past year, NASA’s Lunar Surface Innovation Consortium team collaborated with over 3,900 members from academia, industry, and government on key lunar surface capabilities. Members from across the U.S. and 71 countries participated in two biannual meetings, three lunar surface workshops, and monthly topic meetings, resulting in 10 studies, four reports, and nine conference presentations. 

    Building on previous missions and planning for the future, NASA will conduct more science and technology demonstrations on and around the Moon than ever before. Work toward effort included:

    • Selected a suite of science studies for the Artemis II mission, including studies that focus on astronauts’ health.
    • Launched two CLPS (Commercial Lunar Payload Services) flights with NASA as a key customer, including Firefly’s Blue Ghost Mission One, which landed on the Moon March 2, and Intuitive Machines’ Nova C lunar lander, which touched down on March 6.
      • Experiments and tech demos aboard these flights included an electrodynamic dust shield, lunar navigation system, high-performance computing, collection of more than 9,000 first-of-a-kind images of the lunar lander’s engine plumes, and more.
    • For future CLPS flights, NASA awarded Blue Origin a task order with an option to deliver the agency’s VIPER (Volatiles Investigating Polar Exploration Rover) to the lunar South Pole in late 2027, as well as awarded Firefly another flight, slated for 2030.
    • Teams studied regolith (lunar dirt and rocks) in a simulated lunar gravity environment and tested how solid materials catch fire in space.
    • The agency’s 55-pound CubeSat in lunar orbit, CAPSTONE, exceeded 1,000 days in space, serving as a testbed for autonomous navigation and in-space communications.
    • Published findings from this Artemis I experiment highlighting why green algae may be a very good deep space travel companion.

This data will better inform our understanding of space weather, which is important to help minimize the effects of radiation for future missions with crew.
    • NASA announced Steve Sinacore, from the agency’s Glenn Research Center in Cleveland, to lead the nation’s fission surface power efforts.
    • Selected participants for a second yearlong ground-based simulation of a human mission to Mars, which began in October, as well as tested a new deep space inflatable habitat concept.
    • Completed the agency’s Deep Space Optical Communications experiment, which exceeded all of its technical goals after two years. This type of laser communications has the potential to support high-bandwidth connections for long duration crewed missions in deep space.
    • NASA completed its fourth Entry Descent and Landing technology test in three months, accelerating innovation to achieve precision landings on Mars’ thin atmosphere and rugged terrain. 
    • Other research to support long-duration missions in deep space include how fluids behave in space, farming space crops, and quantum research.

    Through the Artemis Accords, seven new nations have joined the United States, led by NASA and the U.S. Department of State, in a voluntary commitment to the safe, transparent, and responsible exploration of the Moon, Mars, and beyond. With nearly 60 signatories, more countries are expected to sign in the coming months and years. 

    Finally, NASA engaged the public to join its missions to the Moon and Mars through a variety of activities. The agency sought names from people around the world to fly their name on a SD card aboard Orion during the Artemis II mission. NASA also sponsored a global challenge to design the spacecraft’s zero gravity indicator, announcing 25 finalists this year for the mascot design. Artemis II crew members are expected to announce a winner soon.

    NASA’s gold standard science benefits humanity

    In addition to conducting science at the Moon and Mars to further human exploration in the solar system, the agency continues its quest in the search for life, and its scientific work defends the planet from asteroids, advances wildfire monitoring from its satellites, studies the Sun, and more.

    • Garnering significant interest this year, NASA has coordinated a solar system-wide observation campaign to follow comet 3I/ATLAS, the third known interstellar object to pass through our solar system. To date, 12 NASA spacecraft and space-based telescopes have captured and processed imagery of the comet since its discovery in the summer.

    Pioneering aviation research 

    This year saw a major triumph for NASA’s aviation researchers, as its X-59 one-of-a-kind quiet supersonic aircraft made its historic first flight Oct 28. NASA test pilot Nils Larson flew the X-59 for 67 minutes up to an altitude of about 12,000 feet and an approximate top speed of 230 mph, precisely as planned. The flight capped off a year of engine testing including afterburner testing, taxi testing, and simulated flights from the ground — all to make sure first flight went safely and smoothly. The X-59 team will now focus on preparing for a series of flight tests where the aircraft will operate at higher altitudes and supersonic speeds. This flight test phase will ensure the X-59 meets performance and safety expectations. NASA’s Quesst mission also began testing the technologies that they will use to measure the X-59’s unique shock waves and study its acoustics during future mission phases.  

    Researchers also made other major strides to further aviation technologies that will benefit the public and first responders, including live flight testing of a new portable airspace management system with the potential to greatly improve air traffic awareness during wildland fire operations.  

    During the past year, the agency’s aeronautics researchers also:

  • NASA Works with Boeing, Other Collaborators Toward More Efficient Global Flights 

    3 min read

    Preparations for Next Moonwalk Simulations Underway (and Underwater)

    NASA works with Boeing and the ecodemonstrator plane is parked on the tarmac.

    Picture this: You’re just about done with a transoceanic flight, and the tracker in your seat-back screen shows you approaching your destination airport. And then … you notice your plane is moving away. Pretty far away. You approach again and again, only to realize you’re on a long, circling loop that can last an hour or more before you land. 

    If this sounds familiar, there’s a good chance the delay was caused by issues with trajectory prediction. Your plane changed its course, perhaps altering its altitude or path to avoid weather or turbulence, and as a result its predicted arrival time was thrown off.  

    “Often, if there’s a change in your trajectory – you’re arriving slightly early, you’re arriving slightly late – you can get stuck in this really long, rotational holding pattern,” said Shivanjli Sharma, NASA’s Air Traffic Management–eXploration (ATM-X) project manager at the agency’s Ames Research Center in California’s Silicon Valley. 

    This inconvenience to travelers is also an economic and efficiency challenge for the aviation sector, which is why NASA has worked for years to study the issue, and recently teamed with Boeing to conduct real-time tests of an advanced system that shares trajectory data between an aircraft and its support systems. 

    Boeing began flying a United Airlines 737 for about two weeks in October, testing a data communication system designed to improve information flow between the flight deck, air traffic control, and airline operations centers. The work involved several domestic flights based in Houston, as well as a flight over the Atlantic to Edinburgh, Scotland. 

    This partnership has allowed NASA to further its commitment to transformational aviation research.

    NASA’s Air Traffic Management—eXploration project manager

    The testing was Boeing’s most recent with its ecoDemonstrator Explorer program, through which the company works with public and private partners to accelerate aviation innovations. This year’s ecoDemonstrator flight partners included NASA, the Federal Aviation Administration, United Airlines, several aerospace companies, as well as academic and government researchers. 

    NASA’s work in the testing involved the development of an oceanic trajectory prediction service – a system for sharing and updating trajectory information, even over a long, transoceanic flight that involves crossing over from U.S. air traffic systems into those of another country. The collaboration allowed NASA to get a more accurate look at what’s required to reduce gaps in data sharing. 

    “At what rate do you need these updates in an oceanic environment?” Sharma said. “What information do you need from the aircraft? Having the most accurate trajectory information will allow aircraft to move more efficiently around the globe.” 

    Boeing and the ecoDemonstrator collaborators plan to use the flight data to move the data communication system toward operational service. The work has allowed NASA to continue its work to improve trajectory prediction, and through its connection with partners, put its research into practical use as quickly as possible. 

    “This partnership has allowed NASA to further its commitment to transformational aviation research,” Sharma said. “Bringing our expertise in trajectory prediction together with the contributions of so many innovative partners contributes to global aviation efficiency that will yield real benefits for travelers and industry.” 

    NASA ATM-X’s part in the collaboration falls under the agency’s Airspace Operations and Safety Program, which works to enable safe, efficient aviation transportation operations that benefit the flying public and industry. The work is supported through NASA’s Aeronautics Research Mission Directorate.

    NASA is helping shape the future of urban air travel with a new simulation that will manage how electric air taxis and drones can successfully operate within busy areas.  

    The demonstration, held at NASA’s Ames Research Center in California’s Silicon Valley earlier this year, focused on a system called the Strategic Deconfliction Simulation, which helps coordinate flight plans before takeoff, reducing the risk of conflicts in busy urban environments 

    At the event, researchers demonstrated NASA’s Situational Viewer and Demand-Capacity Balancing Monitor, which visualizes air traffic and adjusts flight plans in real time. The simulation demonstrated traffic scenarios involving drone operations throughout the Dallas-Fort Worth area, testing how preplanned flights could improve congestion and manage the demand and capacity of the airspace – ensuring that all aircraft can operate smoothly even in crowded conditions. 

    Working with industry partners is critical to NASA’s efforts to develop and refine technologies needed for future air mobility. During the simulation, the company, ANRA Technologies, demonstrated its fleet and vertiport management systems, which are designed to support the coordination of multiple aircraft and ground operations. 

    “Simulating these complex environments supports broader efforts to ensure safe integration of drones and other advanced vehicles into the US airspace,” said Hanbong Lee, engineer at NASA Ames. “By showcasing these capabilities, we’re delivering critical data and lessons learned to support efforts at NASA and industry.” 

    This demonstration is another step toward the NASA team’s plan to hold a technical capability level simulation in 2026. This upcoming simulation would help shape the development of services aimed at managing aircraft flying in urban areas.  

    The simulation was created through a NASA team from its Air Mobility Pathfinders project, part of the agency’s continuing work to find solutions for safely integrating innovative new aircraft such as air taxis into U.S. cities and the national airspace. By developing advanced evaluations and simulations, the project supports safe, scalable, and publicly trusted air travel in urban areas, paving the way for a future where air taxis and drones are a safe and reliable part of everyday life. 

    The project falls under NASA’s Airspace Operations and Safety Program, which works to enable safe and efficient aviation transportation. 

  • New NASA Sensor Goes Hunting for Critical Minerals

    A pilot signals to a crew member before takeoff from NASA’s Armstrong Flight Research Center in Edwards, California, on Aug. 21, 2025. Accompanying him in the high-flying ER-2 aircraft is one of the most advanced imaging spectrometers in the solar system.
    NASA/Christopher LC Clark

    Called AVIRIS-5, it’s the latest in a long line of sensors pioneered by NASA JPL to survey Earth, the Moon, and other worlds.

    Cradled in the nose of a high-altitude research airplane, a new NASA sensor has taken to the skies to help geoscientists map rocks hosting lithium and other critical minerals on Earth’s surface some 60,000 feet below. In collaboration with the U.S. Geological Survey (USGS), the flights are part of the largest airborne campaign of its kind in the country’s history.

    But that’s just one of many tasks that are on the horizon for AVIRIS-5, short for Airborne Visible/Infrared Imaging Spectrometer-5, which has a lot in common with sensors used to explore other planets.

    NASA’s AVIRIS flies aboard a research plane in this animation, detecting minerals on the ground such as hectorite — a lithium-bearing clay — by the unique patterns of light that they reflect. The different wavelengths, measured in nanometers, look like colorful squiggles in the box on the right. Credit: NASA’s Conceptual Image Lab

    About the size of a microwave oven, AVIRIS-5 detects the spectral “fingerprints” of minerals and other compounds in reflected sunlight. Like its cousins flying in space, the sensor takes advantage of the fact that all kinds of molecules, from rare earth elements to flower pigments, have unique chemical structures that absorb and reflect different wavelengths of light.

    The technology was pioneered at NASA’s Jet Propulsion Laboratory in Southern California in the late 1970s. Over the decades, imaging spectrometers have visited every major rocky body in the solar system from Mercury to Pluto. They’ve traced Martian crust in full spectral detail, revealed lakes on Titan, and tracked mineral-rich dust across the Sahara and other deserts. One is en route to Europa, an ocean moon of Jupiter, to search for the chemical ingredients needed to support life.

    Image cubes illustrate the volume of data returned by JPL imaging spectrometers. The front panel shows roads and fields around Tulare, California, as seen by AVIRIS-5 during a checkout flight earlier this year. The side panels depict the spectral fingerprint captured for every point in the image.
    NASA/JPL-Caltech

    Another imaging spectrometer, NASA’s Moon Mineralogy Mapper, was the first to discover water on the lunar surface in 2009. “That dataset continues to drive our investigations as we look for in situ resources on the Moon” as part of NASA’s Artemis campaign, said Robert Green, a senior research scientist at NASA JPL who’s contributed to multiple spectroscopy missions across the solar system.

    Prisms, black silicon

    While imaging spectrometers vary depending on their mission, they have certain hardware in common — including mirrors, detector arrays, and electron-beam gratings — designed to capture light shimmering off a surface and then separate it into its constituent colors, like a prism.

    Light-trapping black silicon is one of the darkest materials ever fabricated. The technology is standard for JPL’s ultraprecise imaging spectrometers.
    NASA/JPL-Caltech

    Many of the best-in-class imaging spectrometers flying today were made possible by components invented at NASA JPL’s Microdevices Laboratory. Instrument-makers there combine breakthroughs in physics, chemistry, and material science with the classical properties of light discovered by physicist Isaac Newton in the 17th century. Newton’s prism experiments revealed that visible light is composed of a rainbow of colors.

    Today, NASA JPL engineers work with advanced materials such as black silicon — one of the darkest substances ever manufactured — to push performance. Under a powerful microscope, black silicon looks like a forest of spiky needles. Etched by lasers or chemicals, the nanoscale structures prevent stray light from interfering with the sample by trapping it in their spikes.

    Treasure hunting

    The optical techniques used at the Microdevices Laboratory have advanced continuously since the first AVIRIS instrument took flight in 1986. Four generations of these sensors have now hit the skies, analyzing erupting volcanoes, diseased crops, ground zero debris in New York City, and wildfires in Alabama, among many other deployments. The latest model, AVIRIS-5, features spatial resolution that’s twice as fine as that of its predecessor and can resolve areas ranging from less than a foot (30 centimeters) to about 30 feet (10 meters).

    So far this year, it has logged more than 200 hours of high-altitude flights over Nevada, California, and other Western states as part of a project called GEMx (Geological Earth Mapping Experiment). The flights are conducted using NASA’s ER-2 aircraft, operated out of the agency’s Armstrong Flight Research Center in Edwards, California. The effort is the airborne component of a larger USGS initiative, called Earth Mapping Resources Initiative (Earth MRI), to modernize mapping of the nation’s surface and subsurface.

    The NASA and USGS team has, since 2023, gathered data over more than 366,000 square miles (950,000 square kilometers) of the American West, where dry, treeless expanses are well suited to mineral spectroscopy. 

    An exciting early finding is a lithium-bearing clay called hectorite, identified in the tailings of an abandoned mine in California, among other locations. Lithium is one of about 50 minerals at risk of supply chain disruption that USGS has deemed critical to national security and the economy.

    Helping communities capture new value from old and abandoned prospects is one of the long-term aspirations of GEMx, said Dana Chadwick, an Earth system scientist at NASA JPL. So is identifying sources of acid mine drainage, which can occur when waste rocks weather and leach into the environment.

    “The breadth of different questions you can take on with this technology is really exciting, from land management to snowpack water resources to wildfire risk,” Chadwick said. “Critical minerals are just the beginning for AVIRIS-5.”

    More about GEMx

    The GEMx research project is expected to last four years and is funded by the USGS Earth MRI, through investments from the Bipartisan Infrastructure Law. The initiative will capitalize on both the technology developed by NASA for spectroscopic imaging, as well as the expertise in analyzing the datasets and extracting critical mineral information from them.

    Since the space station became operational in November 2000, crew members have produced hundreds of thousands of images of the land, oceans, and atmosphere of Earth, and even of the Moon through Crew Earth Observations. Their photographs of Earth record how the planet changes over time due to human activity and natural events. This allows scientists to monitor disasters and direct response on the ground and study a number of phenomena, from the movement of glaciers to urban wildlife.

    In addition, other activity aboard the space station helps inform long-duration missions like Artemis and future human expeditions to Mars.

  • NASA Flights Study Cosmic Ray Effects for Air, Future Space Travelers

    4 min read

    Preparations for Next Moonwalk Simulations Underway (and Underwater)

    Recent airborne science flights to Greenland are improving NASA’s understanding of space weather by measuring radiation exposure to air travelers and validating global radiation maps used in flight path planning. This unique data also has value beyond the Earth as a celestial roadmap for using the same instrumentation to monitor radiation levels for travelers entering Mars’ atmosphere and for upcoming lunar exploration.

    NASA’s Space Weather Aviation Radiation (SWXRAD) aircraft flight campaign took place August 25-28 and conducted two five-hour flights in Nuuk, Greenland. Based out of NASA’s Langley Research Center in Hampton, Virginia, the mission gathered dosimetry measurements, or the radiation dose level, to air travelers from cosmic radiation. Cosmic radiation is caused by high-energy particles from outer space that originate from our Sun during eruptive events like solar flares and from events farther away, like supernovae in our Milky Way galaxy and beyond.

    “With NASA spacecraft and astronauts exploring the Moon, Mars, and beyond, we support critical research to understand – and ultimately predict – the impacts of space weather across the solar system,” said Jamie Favors, director of NASA’s Space Weather Program at NASA Headquarters in Washington. “Though this project is focused on aviation applications on Earth, NAIRAS could be part of the next generation of tools supporting Artemis missions to the Moon and eventually human missions to Mars.”

    NASA’s Nowcast of Aerospace Ionizing Radiation System, or NAIRAS, is the modeling system being enhanced by the SWXRAD airborne science flights. The model features real-time global maps of the hazardous radiation in the atmosphere and creates exposure predictions for aircraft and spacecraft.

    NASA/Guillaume Gronoff

    “The radiation exposure is maximum at the poles and minimum at the equator because of the effect of Earth’s magnetic field. In the polar regions, the magnetic field lines are directed into or out of the Earth, so there’s no deflection or shielding by the fields of the radiation environment that you see everywhere else.” explained Chris Mertens, principal investigator of SWXRAD at NASA Langley. “Greenland is a region where the shielding of cosmic radiation by Earth’s magnetic field is zero.”

    That means flight crews and travelers on polar flights from the U.S. to Asia or from the U.S. to Europe are exposed to higher levels of radiation.

    The data gathered in Greenland will be compared to the NAIRAS modeling, which bases its computation on sources around the globe that include neutron monitors and instruments that measure solar wind parameters and the magnetic field along with spaceborne data from instruments like the NOAA GOES series of satellites.

    “If the new data doesn’t agree, we have to go back and look at why that is,” said Mertens. “In the radiation environment, one of the biggest uncertainties is the effect of Earth’s magnetic field. So, this mission eliminates that variable in the model and enables us to concentrate on other areas, like characterizing the particles that are coming in from space into the atmosphere, and then the transport and interactions with the atmosphere.”

    The SWXRAD science team flew aboard NASA’s B200 King Air with five researchers and crew members. In the coming months, the team will focus on measurement data quality checks, quantitative modeling comparisons, and a validation study between current NAIRAS data and the new aircraft dosimeter measurements.

    All of this information is endeavoring to protect pilots and passengers on Earth from the health risks associated with radiation exposure while using NASA’s existing science capabilities to safely bring astronauts to the Moon and Mars.

    NASA/Guillaume Gronoff

    “Once you get to Mars and even the transit out to Mars, there would be times where we don’t have any data sets to really understand what the environment is out there,” said Favors. “So we’re starting to think about not only how do we get ready for those humans on Mars, but also what data do we need to bring with them? So we’re feeding this data into models exactly like NAIRAS. This model is thinking about Mars in the same way it’s thinking about Earth.”

    The SWXRAD flight mission is funded through NASA’s Science Mission Directorate Heliophysics Division. NASA’s Space Weather Program Office is hosted at NASA Langley and facilitates researchers in the creation of new tools to predict space weather and to understand space weather effects on Earth’s infrastructure, technology, and society.

  • NASA Lab Builds New Aircraft to Support Complex Flight Research

    2 min read

    Preparations for Next Moonwalk Simulations Underway (and Underwater)

    NASA’s Armstrong Flight Research Center in Edwards, California, is building a new subscale aircraft to support increasingly complex flight research, offering a more flexible and cost-effective alternative to crewed missions.

    The aircraft is being built by Justin Hall, chief pilot at NASA Armstrong’s Dale Reed Subscale Flight Research Laboratory, and Justin Link, a small uncrewed aircraft pilot. The duo is replacing the center’s aging MicroCub subscale aircraft with a more capable platform that will save time and reduce costs. The new aircraft spans about 14 feet from wingtip to wingtip, measures nine-and-a-half feet long, and weighs about 60 pounds.

    The subscale laboratory accelerates innovation by using small, remotely piloted aircraft to test and evaluate new aerodynamic concepts, technologies, and flight control systems. Named after aerospace pioneer Dale Reed, the lab enables rapid prototyping and risk reduction before transitioning to full-scale or crewed flight testing. Its work plays a key role in increasing technology readiness to support NASA’s missions on Earth and beyond.

    Hall and Link are modifying an existing subscale aircraft kit by adding a more powerful engine, an autopilot system, instrumentation, and a reinforced structure. The aircraft will offer greater flexibility for flight experiments, enabling more frequent and affordable testing compared to crewed aircraft.

    One example of its potential is the Robust Autonomous Aerial Recapture project, which uses sensors and video with advanced programming to learn and adapt for mid-air capture. The system relies on a magnetic connection mechanism integrated onto the two aircraft.

    This capability could support future science missions in which a mothership deploys drones to collect samples, recharge, and redeploy for additional missions, saving fuel, reducing cost, and increasing efficiency. Aerial recapture work is funded by the NASA Armstrong Center Innovation Fund and the Space Technology Mission Directorate.

    As we observe National Aviation Day Tuesday – a tribute to Orville Wright’s birthday – let’s reflect on both America’s and NASA’s aviation heritage and share how we are pushing the boundaries of flight for the nation’s future. Modern NASA grew from the National Advisory Committee for Aeronautics (NACA), an agency created by Congress in 1915 to advance U.S. aviation. When President Eisenhower signed the National Aeronautics and Space Act of 1958, NACA was dissolved and its people, laboratories and research programs became the foundation of NASA. These intrepid men and women are the cornerstone of the world’s most capable aerospace industry and their legacy lives on today across all facets of the agency.

    The most significant aviation milestones in the twentieth century were achieved through both NASA and NACA research and through the courage of pioneering test pilots. In 1947, the joint NACA/U.S. Army Air Forces (later the U.S. Air Force, or USAF) developed Bell X‑1 flew faster than the speed of sound, shattering the mythical “sound barrier.” This breakthrough, enabled by NACA wind-tunnel data and high-speed aerodynamic expertise, made supersonic flight a reality and led directly to NACA Test Pilot Scott Crossfield being the first human to reach Mach 2, twice the speed of sound, in the Douglass DD558-II a mere six years later. During the X‑15 program of the 1960s, legendary NASA Test Pilots Joe Walker, John McKay, Neil Armstrong, Milt Thompson, and Bill Dana piloted nearly half of the program’s sorties and flew the rocket-powered research plane at altitudes up to 354,200 feet and speeds of 4,520 mph (Mach 6.7).

    The NASA/USAF-developed North American X‑15 became the world’s first reusable hypersonic aerospace vehicle, reaching space (above 50 miles altitude) on 11 separate missions; it provided essential data on materials, flight control and pilot physiology that helped shape the agency’s Mercury, Gemini, Apollo and Space Shuttle programs. These milestones remind us that our nation’s accomplishments are the result of visionary NASA, Department of Defense, industry engineers, and test pilots working together to achieve audacious goals.

    NASA’s commitment to aviation innovation did not stop with early experimental high-speed aircraft. In the 1990s, the U.S. general aviation industry faced a steep decline – production fell from 18,000 aircraft in 1978 to fewer than 1,000 in 1993. NASA saw an opportunity: we envisioned a Small Aircraft Transportation System in which safe, efficient general aviation planes could revitalize a critical industry. To enable that vision, NASA partnered with the Federal Aviation Administration, industry, universities, and non‑profits to create the Advanced General Aviation Transport Experiments (AGATE) consortium in 1994. The AGATE consortium developed safer cockpit displays, crashworthiness improvements, efficient airfoils, and modern manufacturing techniques. These innovations transformed U.S. general aviation, helping spawn industry successes like the Cirrus SR20 and SR22 family of aircraft, which incorporate NASA-derived composite structures and safety features.

    In 2004, NASA’s unmanned X‑43A Hyper-X broke world speed records for air‑breathing aircraft, flying at Mach 6.8 and later Mach 9.6. Those flights demonstrated practical scramjet propulsion and proved that hypersonic cruise flight is achievable.

    Today, we are building on this legacy and pushing the envelope with the X-59. Later this year, NASA Test Pilot Nils Larson will usher in a new era of quiet supersonic flight when he pilots the X‑59 Quesst’s first flight out of NASA’s Armstrong Flight Research Center in Edwards, California. The experimental aircraft, designed to fly at 1.4 times the speed of sound while producing only a gentle sonic “thump” instead of the traditional loud sonic boom, will provide data vital to achieving the vision in President Donald J. Trump’s Executive Order “Leading the World in Supersonic Flight.”

    Hypersonics research is another pillar to our 21st‑century vision. Lessons from the X‑15, X‑43, and Space Shuttle inform our study of high-temperature materials, flight controls and propulsion. These technologies will not only bolster national security but will also spur the development of ultrafast civil transports, shrinking the world even further. We are also investing in 21st century propulsion, additive manufacturing, and autonomy for light aircraft while also developing advanced air traffic control systems. Partnering with U.S. aerospace industry and the FAA, we will bring true 21st century technology into light general aviation aircraft, ensuring America remains at the forefront of aviation innovation.

    I am continually inspired by the ingenuity of our past and the promise of our future. Our roots in NACA remind us that a small group of dedicated men and women can change the world. From the Wright brothers’ pioneering work to the supersonic and hypersonic records set by NASA pilots and vehicles, we have consistently expanded the boundaries of what is possible in flight. Looking ahead, our pursuit of quiet supersonic aircraft, hypersonic technologies, and revitalized general aviation will keep the U.S. aviation industry strong and sustainable for decades to come. On National Aviation Day, we celebrate not only our history but also the teamwork and vision that will carry us into the next century of flight.

    Higher, Farther, Faster!

    The first “A” in NASA stands for Aeronautics – so naturally that means today, Aug. 19, National Aviation Day, is one of our favorite days all year!

    National Aviation Day was first proclaimed in 1939 by President Franklin Roosevelt to celebrate the birthday of aviation pioneer Orville Wright, who, with his brother Wilbur, in 1903, were the first humans to achieve powered flight.

    Each year since the President first marked the occasion, sky-faring Americans have come together on this date in an annual celebration of flight – a time to revel in spreading our wings and slipping the surly bonds of Earth.

    All of us at NASA share in that celebration. We love everything about flight, whether it’s into space or within Earth’s atmosphere.

    Our aeronautical innovators are dedicated to improving the design of airplanes to carry on pioneering new technologies in high-speed flight, airframes and propulsion methods, aerospace engineering modelling, and automating airspace and safety management.

    Our heritage in aviation research goes back more than 100 years. We’ve helped air travel become a safe, efficient, reliable form of transportation. If you’re heading to an airport, keep an eye out for these NASA-developed aviation technologies you might see on your flight:

    How Will You Celebrate?

    How else can you celebrate National Aviation Day? Here are seven ideas:

    Visit your local science museum or NASA visitor center

    Explore your local science center for exhibits about aviation and how an airplane flies. And if you live within a short drive from Norfolk, Virginia; Cleveland, or San Francisco, you might consider checking out the visitor centers associated with NASA’s Langley Research Center, Glenn Research Center, or Ames Research Center, respectively. These major NASA field centers play host to the majority of NASA’s aeronautics research. (NASA’s Armstrong Flight Research Center, the fourth of NASA’s aeronautics centers, is located within the restricted area of Edwards Air Force Base in California so they do not have a public visitor’s center.)

    Watch an aviation-themed movie

    There’s no shortage of classic aviation-themed movies available to watch in any format (streaming, DVD, cinema, library rentals, etc.), and with any snacks (popcorn, nachos, gummies, etc.). We dare not attempt a comprehensive list, but a good place to start is our documentary “X-59: NASA’s “Quesst” for Quiet Supersonic Flight” available to stream on NASA+.

    Build an airplane

    Why not? It doesn’t have to be big enough to actually fly in – plastic model kits of the world’s most historic aircraft can be just as rewarding and just as educational, especially for kids who might be thinking about a career as an engineer or technician. In fact, many astronauts will tell you their love of aviation and space began with putting models together as a child. Another idea: Grab some LEGO bricks and build the airplane of your dreams. Or make it easy on yourself, fold a paper airplane and shoot it across the room.

    Take an introductory flight lesson

    Pilots will tell you there is a wonderful sense of freedom in flying, not to mention the incredible views and the personal sense of accomplishment. At the same time, being a pilot is not for everyone, but you won’t know unless you try! Many general aviation airports in the nation have a flight school that may offer an introductory flight lesson at a discounted price. And if you want a taste of flight without leaving the ground, computer desktop flight simulators such as Microsoft Flight Simulator or X-Plane are popular choices and can get you into the virtual sky in short order.

    Visit your local library or download a NASA e-book

    Aviation-themed books, whether fact or fiction, are all over the shelves of your local library – literally. That’s because there’s no single Dewey Decimal number for aviation. A book about aviation history will be in a different section of the library than a book about how to design an airplane. And creative nonfiction books such as the Mark Vanhoenacker’s “Skyfaring,” or autobiographies such as Eileen Collins’ “Through the Glass Ceiling to the Stars,” are off on yet another shelf. Don’t hesitate to ask your librarian for help. And when you get back from the library, or while still there, jump online and check out the NASA e-books you can download and own for free.

    Have a plane spotting picnic near an airport

    At Washington’s National Airport, it’s Gravelly Point. In Tampa, Florida it’s International Mall. If you live near a major international airport, chances are you know the best place where the locals can go to watch aircraft take off and land up close. Be sure to take heed of any security restrictions about where you can and can’t go. But once you have your spot picked out, then load up your picnic basket and camp out for an evening of plane spotting. See how many different types of airplanes you can count or identify.

    Follow what we’re doing to transform aviation

    NASA’s aeronautical innovators are working to transform air transportation to meet the future needs of the global aviation community. Sounds like a big job, right? It is and there are many ways in which NASA is doing this. Improving an airplane’s aerodynamics, making airplanes more efficient and quieter, working with the Federal Aviation Administration to improve air traffic control – the list could go on for many thousands of more words. Bookmark our NASA Aeronautics topic page and follow us on social media @NASAaero.

    So remember this National Aviation Day, NASA is with you when you fly!

  • NASA Tests Research Aircraft to Improve Air Taxi Flight Controls

    Flying the friendly skies may one day include time-saving trips in air taxis to get from point A to point B – and NASA researchers are currently working to make that future a reality.

    They are using wind tunnel and flight tests to gather data on an electric Vertical takeoff and landing (eVTOL) scaled-down small aircraft that resembles an air taxi that aircraft manufacturers can use for their own designs.

    As air taxis take to the skies, engineers need real-world data on air taxi designs to better understand flight dynamics and design better flight control systems. These systems help stabilize and guide the motion of an aircraft while in flight, making sure it flies safely in various conditions.

    Currently, most companies developing air taxis keep the information about how their aircraft behaves internal, so NASA is using this small aircraft to produce public, non-proprietary data available to all.

    “NASA’s ability to perform high-risk flight research for increasingly automated and autonomous aircraft is really important,” said Siena Whiteside, who leads the Research Aircraft for eVTOL Enabling techNologies (RAVEN) project. “As we investigate these types of vehicles, we need to be able push the aircraft to its limits and understand what happens when an unforeseen event occurs…”

    For example, Whiteside said, “…when a motor stops working. NASA is willing to take that risk and publish the data so that everyone can benefit from it.”

    Testing Air Taxi Tech

    By using a smaller version of a full-sized aircraft called the RAVEN Subscale Wind Tunnel and Flight Test (RAVEN SWFT) vehicle, NASA is able to conduct its tests in a fast and cost-effective manner.

    The small aircraft weighs 38 pounds with a wingspan of six feet and has 24 independently moving components.

    Each component, called a “control effector,” can move during flight to change the aircraft’s motion – making it an ideal aircraft for advanced flight controls and autonomous flight research.

    The testing is ongoing at NASA’s Langley Research Center in Hampton, Virginia.

    Researchers first used the center’s 12-Foot Low-Speed Tunnel in 2024 and have since moved on to flight testing the small aircraft, piloting it remotely from the ground. During initial flight tests, the aircraft flew while tied to a tether. Now, the team performs free flights.

    Lessons learned from the aircraft’s behavior in the wind tunnel helped to reduce risks during flight tests. In the wind tunnel, researchers performed tests that closely mirror the motion of real flight.

    While the scale aircraft was in motion, researchers collected information about its flight characteristics, greatly accelerating the time from design to flight.

    The team also could refine the aircraft’s computer control code in real time and upload software changes to it in under 5 minutes, saving them weeks and increasing the amount of data collected.

    Partners in Research

    NASA developed the custom flight controls software for RAVEN SWFT using tools from the company MathWorks.

    NASA and MathWorks are partners under a Space Act Agreement to accelerate the design and testing of flight control approaches on RAVEN SWFT, which can apply to future novel aircraft.

    The work has allowed NASA’s researchers to develop new methods to reduce the time for an aircraft to achieve its first flight and become a finished product.

    RAVEN SWFT serves as a steppingstone to support the development of a potential larger, 1,000 pound-class RAVEN aircraft that will resemble an air taxi.

    This larger RAVEN aircraft is being designed in collaboration with Georgia Institute of Technology and also would serve as an acoustical research tool, helping engineers understand the noise air taxi-like aircraft create.

    The larger aircraft would allow NASA to continue to collect data and share it openly.  

    By performing flight research and making its data publicly available, NASA aims to advance U.S. leadership in technology development for safe, quiet, and affordable advanced air mobility operations.
