This will be the second flight to the space station for Watkins, who was selected as a NASA astronaut in 2017. Watkins grew up in Lafayette, Colorado, and earned an undergraduate degree in geological and environmental sciences from Stanford University, as well as a doctorate in geology from the University of California, Los Angeles. As a geologist, she studied the Martian surface and was a member of the Curiosity rover science team at NASA’s Jet Propulsion Laboratory in Southern California. Watkins first launched to the space station as a crew member aboard NASA’s SpaceX Crew-4 mission, spending a total of 170 days in space across space station Expeditions 67/68 in 2022. She will be the first NASA astronaut to launch aboard a SpaceX Dragon spacecraft twice.

Selected as a NASA astronaut in 2021, Delaney earned a bachelor’s degree in mechanical engineering at the University of North Florida and a master’s degree in aerospace engineering at the Naval Postgraduate School. The Florida native is a distinguished naval aviator who participated in exercises throughout the Asia Pacific region and conducted missions in support of Operation Enduring Freedom. As a test pilot, Delaney evaluated developmental aircraft systems and served as a test pilot instructor. He also worked as a research pilot at NASA’s Langley Research Center in Hampton, Virginia, where he supported airborne science missions. This is the first spaceflight for Delaney.

The Crew-13 mission also is the first spaceflight for Kutryk. Prior to his selection as a CSA astronaut in 2017, he served as a CF-18 fighter pilot, flying missions in support of Canada’s NATO, U.N., and North American Aerospace Defense Command commitments. A native of Fort Saskatchewan, Alberta, Kutryk also worked as an experimental and operational test pilot at the Aerospace Engineering Test Establishment in Cold Lake, Alberta. Kutryk received a bachelor’s degree in mechanical engineering from the Royal Military College of Canada in Kingston, Ontario, and he is a distinguished graduate of the United States Air Force Test Pilot school in Edwards, California. He has master’s degrees in space studies, flight test engineering, and defense studies.

This mission will be Teteryatnikov’s first trip to the orbiting laboratory. He graduated from the Naval Academy, St. Petersburg, Russia, in 2011 as an engineer specializing in ship power plant operations. Before his selection as a test cosmonaut, Teteryatnikov served in various naval engineering roles, including undersea vessels and specialized engine room operations. He was selected for the Gagarin Research and Test Cosmonaut Training Center Cosmonaut Corps in 2021 and has served as a test cosmonaut since 2023.

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 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.

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.

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.

Landslides in Alaska. Air quality in Atlanta. Fire clouds out West. From the Arctic fringes to farm country, NASA’s newest class of suborbital Earth Venture missions is gearing up to deliver science that will benefit communities in the United States and beyond. 

The six projects will mobilize hundreds of scientists and pilots from NASA, the U.S. Navy, universities, and other institutions over the next several years. While the investigations range across topics, a defining feature of suborbital missions is the use of sensors mounted on aircraft. 

Airborne remote sensing serves as a bridge between ground-based instruments and satellites. Data collected via planes, helicopters, drones, and balloons can fill in gaps in computer models used by weather forecasters, city planners, and others.  

When wildfires create their own weather 

The first project to take wing this summer is Injected Smoke and PYRocumulonimbus Experiment (INSPYRE), led by the Naval Research Laboratory. From mission headquarters in Colorado, the team will chase one of the least understood forms of severe weather on Earth: towering “fire clouds” generated when extreme wildfires burn hot enough to brew their own thunderstorms.  

Smoky and crackling with lightning, these unique storms can create blind spots for aviators above and spark new blazes below. Measuring and mapping the dangerous storms as they develop in real-time will help scientists forecast them in the future. Several aircraft, including NASA’s high-altitude ER-2, flying out of Montana, will carry a large suite of instruments over wildfire-generated storm systems. Among them will be two state-of-the-art infrared wildfire trackers, which were developed at NASA’s Jet Propulsion Laboratory (JPL) in Southern California and will be flying as part of the agency’s FireSense program.  

Testing the air over farmland, megacities 

Agricultural emissions represent an important and understudied part of Earth’s land and atmosphere systems. The FarmFlux mission, which kicks off this year, will deploy more than a dozen sensors to measure ozone, methane, ammonia, particulates, and other pollutants rising from agricultural lands and animal farms stretching from the Midwest to California’s Central Valley. These emissions affect human health, global climate, and stratospheric ozone. The mission is led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, along with Colorado State University, and Boston University. 

Two North American cities with air quality concerns are Atlanta and Mexico City. But the causes differ, with weather and terrain playing a role. To explore these differences, the Hemispheric Airborne Measurements of Air Quality (HAMAQ) mission will investigate areas of poor air in the two capitals and test how satellite information can help forecasting and mitigation efforts. The team will deploy two aircraft at different altitudes: NASA’s P-3B will fly close to the surface, directly measuring fine particle and gaseous pollutants, while the recently acquired 777 science jet will soar high above, mapping pollution with remote sensors.  NASA’s Langley Research Center in Hampton, Virginia, is leading the mission. 

Fast-changing north 

As the Arctic warms at least twice as fast as the rest of Earth, data collected today can help guide communities on the front lines of change.  

The Snow4Flow campaign, led by the University of Arizona, seeks to measure and model how far and fast glaciers are retreating in the far north. Traversing remote icescapes across Alaska, the Yukon, Arctic Canada, Greenland, and Svalbard, Norway, they’ll sound both the near-surface and frozen depths of hundreds of glaciers while flying over in a modernized WWII-era aircraft outfitted with a scanning laser altimeter and two custom radars. Their observations, combined with satellite data and advanced models of snowfall and glacier flow, will advance our understanding of how glaciers behave in different regions of the Arctic. The mission seeks to uncover not just what these glaciers look like beneath the surface today, but the processes that will drive changes in the future. 

As permafrost thaws, rivers on the doorstep of the Arctic become conveyor belts of carbon and sediment. NASA Goddard, and the City College of New York lead a multidisciplinary team studying how rivers, lagoons, and estuaries across Alaska’s North Slope interact with the Arctic Ocean. The project, called Frontlines of Rapidly Transforming Ecosystems (FORTE) will combine optical and radar measurements from satellites, planes, high-tech research vessels, drones, and underwater autonomous systems to track microscopic marine life, water flow, and chemistry. The team will collaborate with local and tribal communities to sustain observations over time and apply NASA assets to address emerging local needs and decision-making priorities.  

Landslide triggers 

When a slow-moving landslide in California suddenly collapsed and buried a section of coastal highway in 2017, scientists at NASA JPL wanted to know how precipitation swings played a role. JPL studies how water infiltrates and destabilizes hillslopes all over the world. The Landslide Change Characterization Experiment (LACCE) project will combine airborne synthetic aperture radar with land-based sensors to track how slopes in California are responding to a world of intensifying droughts and downpours. The project also takes aim at emerging landslide hazards in Alaska, where rapidly retreating glaciers are accelerating slope movements that have the potential to create mega-tsunamis.  

NASA’s Earth Venture Suborbital program, designed to be nimble and high impact, was established following a recommendation by the National Research Council in 2007. In the decades since, teams have studied phenomena, including blizzards, coral reefs, and ocean whirlpools.

Fifty years ago, NASA’s Viking 1 and 2 landers made the first successful landings on Mars, opening a new era in planetary exploration. Behind that achievement was a team at NASA’s Langley Research Center in Hampton, Virginia, whose steady leadership and technical expertise helped turn an ambitious idea into a mission that reshaped how we explore other worlds.

Building the Blueprint for Mars

NASA selected Langley in 1968 to lead the massive Viking project, the first U.S. mission designed to land safely on Mars and search for signs of life. Project Manager James S. Martin Jr. set the tone from the start. He wanted clear priorities, tough engineering reviews, and the discipline to test every system until the team was confident it would perform on Mars.

Entry, Descent, and Landing

Langley engineers faced a challenge unlike anything attempted before: slowing a spacecraft plunging into the Martian atmosphere at more than 10,000 miles per hour. So they leaned into their expertise in atmospheric entry aerodynamics, heat shielding, and parachute technology. Their work produced the protective aeroshell and heat shield, as well as the supersonic parachute. These systems didn’t come from theory alone — they were shaped by years of wind‑tunnel tests, analysis, and problem‑solving. Langley still excels at entry, descent, and landing systems today.

Science and Safety, Hand in Hand

Langley also helped create a new approach to finding safe landing sites. Teams combined images from Viking’s orbiters with radar data from Earth‑based observatories to identify regions that balanced scientific value with engineering safety — a method now standard for Mars missions.

Viking also changed how mission teams operated. Engineers and scientists adopted the sol — a Martian day slightly longer than 24 hours — to keep daily work aligned with local time on Mars, a practice still used for surface missions.

A Mission Reborn: From Voyager to Viking

Viking grew out of a pivotal program shift. The earlier Voyager Mars lander concept was canceled because it was too costly and risky, relying on two large landers stacked on a single Saturn V rocket. Langley helped chart a more realistic path forward, pairing each lander with its own orbiter and using Titan IIIE‑Centaur rockets instead. The new design preserved scientific ambition while making the mission achievable.

A Legacy That Endures

Viking provided an early model for how NASA could explore the solar system: scout with orbiters, certify landing sites with real data, and land only with systems tested well beyond their limits. That “planetary playbook,” shaped heavily by Langley, provided a guide for future Mars missions like Curiosity and Perseverance.

The two landers returned thousands of images and groundbreaking data, revealing Mars as a world with weather, geologic history, and complexity that scientists are still studying today. And while no human has ever set foot on the Martian surface, Viking proved that reaching another planet — and working on it ­­— was within reach.

As the 50th anniversary of those landings arrives, Langley’s influence is unmistakable. The center continues to advance new entry, descent, and landing technologies, and explore concepts that will support future human explorers. The same spirit that guided Viking still drives the work happening in Hampton today — steady, curious, and always looking toward the next horizon.

“Touchdown, we have touchdown!” At 5:12 a.m. PDT, July 20, 1976, mission controllers at NASA’s Jet Propulsion Laboratory erupted in cheers as they learned that the Viking 1 lander had survived its descent through the thin Martian atmosphere. Forty minutes later, the lander’s first image began to appear on their monitors, slowly forming line by line from left to right. For the first time, humans were able to see Mars’s rocky terrain from its surface.

Dr. Thomas Mutch, leader of the Viking lander imaging team, described the moment: “I studied the black screen, waiting for that narrow strip that will signal the first few lines of the first picture. And it appeared. A sliver of electronic magic. Areas of brightness and darkness. The picture begins to fill the screen. Rocks and sand are visible and — finally at the far right — one of the spacecraft foot pads, a symbolic artifact that stamps our accomplishment with the sign of reality. Time and time again I repeat, ‘It’s incredible.’”

Fifty years ago today, the Viking 1 lander became NASA’s first robot to explore Mars’s surface and begin the search for signs of life in our solar system. Viking 1 was joined six weeks later by its twin lander, Viking 2, which explored a different region of Mars, while two mission orbiters that delivered the landers to the Red Planet continued to collect data from space and helped relay communications to Earth.

Seattle, Washington—sometimes known as the “Emerald City”—was glimmering in the morning sunlight when an astronaut aboard the International Space Station took this photo on June 16, 2026. The city’s parks and tree-filled neighborhoods lend a lush, green look to the metropolis, while tall buildings downtown cast long shadows and ships navigate surrounding waterways.

The broad contours of the city’s landscape and the water around it owe their shape to the advance and retreat of glaciers during the last ice age. Between roughly 18,000 and 16,000 years ago, the Puget lobe of the Cordilleran ice sheet covered the area in a mass of ice up to 3,300 feet (1,000 meters) thick. The glacier scoured the basins now occupied by Puget Sound and the region’s lakes. 

The glacier left its mark above water, too. Several of Seattle’s notorious hills (of which there are seven or more, depending on who’s counting) are drumlins. These elongated mounds of glacial debris run north-south, parallel to the direction of the ice’s movement. East-west travelers in the city, facing challenging ups and downs, may attest to this topographic trend.

The ice also transported large boulders called glacial erratics from more northerly locations and deposited them around the region. A particularly large erratic, the Wedgwood Rock, stands about 20 feet (6 meters) tall and draws its name from the North Seattle neighborhood in which it rests.

In more recent times, humans have undertaken projects to rework the topography. Notable alterations include leveling Denny Hill north of downtown and filling in tideflats at the mouth of the Duwamish River south of downtown, which created around 1,300 acres of new land. Seattle’s professional sports stadiums sit atop this fill.

This photo was acquired after several development projects to update waterfront infrastructure downtown, initiated in 2010, were completed. These include a new ferry dock and terminal, a rebuilt seawall, and a tunnel to replace an above-ground highway and create more inviting public access to the waterfront.

Some replumbing of the region’s waterways is apparent from the astronaut’s perspective, as well. In the 1910s, the Army Corps of Engineers built canals on either side of Lake Union to connect Puget Sound (an inlet of the Pacific Ocean) with Lake Washington. Starting in 1916, the Montlake Cut connected Lake Washington to Lake Union, and the Ballard Locks, northwest of Lake Union, began raising and lowering watercraft between the freshwater lakes and tidal Puget Sound. As a result of this project, Lake Washington’s water level dropped about 9 feet (3 meters) and ceased draining from its natural outlet at its southern end.

Today, the waters in and around Seattle support many uses: container ships, cruise ships, car and passenger ferries, floatplanes, and recreational craft ply the sound and lakes. And as for Seattle’s emerald nickname, pockets of old-growth forest still exist within city limits, containing centuries-old trees such as Douglas fir, Western red cedar, and Western hemlock. Seattleites often spot wildlife such as bald eagles, coyotes, and sea lions in the city’s various habitats.

Astronaut photograph ISS074-E-723719 was acquired on June 16, 2026, with a Nikon Z9 digital camera using a focal length of 560 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The image was taken by a member of the Expedition 74 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Lindsey Doermann.

NASA Pushes New Wing Design to Find Structural Limits

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.

The Growing Crescent of Mars as NASA’s Psyche Mission Approaches

PNG (3.48 MB)

Description

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. The series begins with the smallest crescent at the center of the of the image as Mars is farthest from the spacecraft, and progressively grows as the spacecraft gets closer. After these views were captured by the spacecraft’s multispectral imager instrument, Mars began to overfill the field of view as Psyche made close approach with the planet and captured a series of high-resolution images of the surface.

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. Using these views of the approach, close approach, and departure from Mars, the Psyche team compiled a stunning time-lapse of its entire Mars encounter.

Feedback

In April 2026, NASA’s Office of the Chief Health and Medical Officer (OCHMO) initiated a working group to review updated VTE case information, additional data gathered revealing altered blood flow status within a cohort of astronauts, and discuss progress of research and clinical activities intended to mitigate the risk of VTE during spaceflight with new evidence-based clinical practice recommendations.

Recommendations

The following is a summary of the working group’s recommendations:

• The working group’s conclusions emphasized that stasis in the left internal jugular vein (IJV) is consistently viewed as a dominant risk factor for VTE in microgravity, though there is active debate regarding the relative contributions of slow qualitative flow, endothelial factors and/or retrograde flow.
• Limitations of current in-flight ultrasound capabilities to accurately measure stasis/slow flow was cited as a concern, especially if using only stasis as a factor for indicating the need for prophylaxis.
• Additional review of assessing stasis with ultrasound in-flight was recommended.
• After reviewing the risk factors, additional discussions following the working group led to the majority of the panel agreeing that stasis and retrograde flow warranted use of prophylaxis.
• The working group also recommended assessing all other risk factors other than stasis to also determine when prophylaxis is warranted.
• Based on a literature review and summary of the panel contributions, a VTE Risk Score for Astronauts Algorithm was developed, which includes providing anticoagulation prophylaxis for stasis alone, or a combination of other thrombosis risk factors that are weighted by terrestrial literature.

Risk of Venous Thromboembolism During Spaceflight

NASA initially formed a working group in October 2024 after diagnosing venous thromboembolisms (VTEs) in astronauts during ISS missions. Experts reviewed case data, updated Clinical Practice Guidelines, and examined possible causes.

After a slow start to Canada’s 2026 fire season, activity picked up by the end of June amid dry, warm conditions and returned closer to the 25-year average. By mid-July, almost 850 fires were actively burning across the country, according to the Canadian Interagency Forest Fire Centre. More than 180 of those were burning in Ontario.

This NOAA-21 image, acquired on the afternoon of July 14, 2026, shows smoke billowing from the Ontario fires. Winds carried the smoke primarily southeast over much of the southern part of the province, as well as parts of Quebec and the U.S. Midwest and Northeast, tinting the sky shades of gray and yellow and the Sun orange in many areas.

The smoke’s impact on air quality varied, depending largely on altitude. In areas where smoke was high in the atmosphere, air quality impacts were negligible; where it drifted closer to the ground, conditions worsened. Air quality in Toronto, for instance, reached unhealthy levels, according to AirNow. People in the southern parts of the province were also grappling with a heat wave, compounding the health risks.

Much of the smoke came from fires in Northwestern Ontario, where eight blazes saw significant growth on July 13 and 14. The fires prompted officials to issue evacuation orders for several communities in this part of the province, according to news reports.

As of July 14, fires across Canada have burned 1.9 million hectares (4.7 million acres) since the start of the year—still well below the season totals from the extreme fire years of 2023 and 2025. How the rest of the season plays out remains to be seen. A seasonal fire outlook—compiled by wildland fire experts from the U.S., Canada, and Mexico—shows where fire conditions are more or less likely through July, August, and September.

NASA Uses Subscale Aircraft to Accelerate Flight Innovation

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.

A meteorite recovered immediately upon its fall to Earth on July 16, 2024, is helping NASA scientists uncover new clues about ancient water, the chemical evolution of primitive asteroids, and the ingredients that may have helped make life possible throughout the early solar system.

This rapid recovery began when an amateur astronomer in New Jersey quickly recognized that a newly fallen meteorite had landed on his property. Recognizing its scientific value and wearing protective gloves, he collected the fragments and stored them in aluminum foil and glass containers, which preserved delicate minerals and organic compounds that are often altered by moisture, weather, and contamination.

As the meteorite fell to Earth, cameras across New Jersey captured its fiery passage through the atmosphere. Scientists used these observations to reconstruct the fireball’s trajectory and, after recovering the meteorite, combined this data with laboratory analyses to determine where in the solar system the rock most likely originated. In a study published Wednesday in the journal Science Advances, researchers found evidence that ancient salty water altered minerals within the meteorite’s parent asteroid, preserving unique minerals and a rich inventory of organic compounds.

“When we have both a documented fireball and a quick recovery of its meteorite, we can learn not only what the rock is made of, but where it came from in the asteroid belt,” said Peter Jenniskens, meteor astronomer at both NASA’s Ames Research Center in California’s Silicon Valley and the SETI Institute, and lead author of the study.

Named for the township where it was recovered, the Hillsborough meteorite belongs to a class of carbon-rich meteorites known as CM carbonaceous chondrites. These primitive rocks preserve some of the oldest materials in the solar system, recording the chemical processes that shaped asteroids more than 4.5 billion years ago.

While examining the unusually pristine meteorite, researchers found a mosaic of tiny broken-up rocks and noticed that some contained unusually high concentrations of sodium — an unexpected finding for this type of meteorite. The surprising signal prompted a closer investigation using powerful electron microscopes that allowed scientists to examine the meteorite from the millimeter scale down to individual atoms. By combining observations across multiple scales, researchers reconstructed the history of the minerals and the fluids that once flowed through them.

These analyses revealed microscopic fractures filled with sodium-rich material left behind by ancient brines. Unlike pure water, brines contain dissolved salts that allow them to transport elements and chemically alter the rocks they move through. In the case of the Hillsborough sample, those ancient fluids altered the asteroid’s minerals and left behind chemical evidence that remained preserved for billions of years.

Scientists were also able to detect fragile sodium-carbonate salts that normally react with moisture in Earth’s atmosphere before they can be studied. Jangmi Han, a paper co-author and mineralogist at NASA’s Johnson Space Center in Houston, identified evidence of ancient brines preserved within microscopic fractures. Similar salts were identified in samples returned from the asteroids Bennu and Ryugu by NASA’s OSIRIS-REx mission and JAXA’s (Japan Aerospace Exploration Agency) Hayabusa2 mission. However,Hillsborough marks the first time the salts have been identified in a CM carbonaceous chondrite meteorite, offering a new glimpse into the surfaces of the primitive asteroids that produced these meteorites.

Together, these findings suggest that ancient, salt-rich brines were more widespread among primitive asteroids than previously recognized, and provide scientists with new opportunities to compare how water altered different asteroid bodies across the early solar system.

“The chips of the most salt-rich bits of this meteorite are quite comparable to the samples returned by the Hayabusa2 and OSIRIS-REx missions,” said Mike Zolensky, a meteorite researcher at NASA Johnson and co-author of the study. “They’re not identical. They’re different in some very interesting ways, but they’ve seen very similar processes.”

Scientists expected Hillsborough to contain a rich suite of organic compounds because it is a CM carbonaceous chondrite. What made the meteorite exceptional was how quickly it was recovered, allowing researchers to study those compounds before prolonged exposure to Earth’s environment could contaminate the sample.

“One of the big surprises for me when we analyzed a small chip of the Hillsborough meteorite was the complexity of amino acids and other organic compounds,” said Danny Glavin, senior scientist in the Astrobiology Analytical Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and co-author of the study.

Its diversity of amino acids and other organic compounds is, comparable to the Murchison meteorite, a nearly 100-kilogram carbonaceous chondrite that fell in Australia in 1969 and became the benchmark for extraterrestrial organic chemistry.

“It’s just more proof that the chemical building blocks of life could have been delivered — and are still being delivered — to Earth today by these carbonaceous asteroid fragments,” said Glavin, who was a co-investigator on OSIRIS-REx, leading an international team that studied the organic composition of the samples delivered to Earth from asteroid Bennu in 2023.

Understanding the Hillsborough meteorite required expertise from multiple scientific disciplines.

Astronomers reconstructed the meteorite’s journey through space, finding evidence that it may have originated from the Erigone asteroid family in the inner asteroid belt, home to the asteroid Donaldjohanson, which was visited in 2025 by NASA’s Lucy spacecraft. Mineralogists identified evidence of ancient brines preserved within microscopic fractures, while organic chemists analyzed the meteorite’s inventory of amino acids and other organic compounds.

“Together, those complementary studies are helping scientists build one of the clearest pictures yet of how primitive asteroids such as the asteroid Erigone evolved chemically over billions of years,” said Jenniskens.

Researchers continue to study the Hillsborough meteorite, revealing new details about how water transformed primitive asteroids and shaped the early solar system.

By tracing the history of water on primitive asteroids, scientists are learning how water and the chemical ingredients for life were distributed throughout the early solar system.

“If you follow the water through the solar system, you’re actually following life,” Zolensky said. “Following the history of water through the solar system is an essential part of understanding the origin of life.”

How NASA’s Artemis III Lander Test Will Pave Way for Moon Landings

Before Artemis astronauts land on the Moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the Moon, will support astronaut safety and mission success for crewed lunar landings.

NASA is working with two American companies to develop the human landing systems that will safely transport astronauts from lunar orbit to the Moon’s surface and back for future Artemis missions. For Artemis III, both SpaceX and Blue Origin will fly test versions, or test articles, of the crewed landers that will be used for future Moon landings. The lander test articles will launch by commercial rockets, while the Artemis III crew will launch to low Earth orbit in Orion atop the agency’s SLS (Space Launch System) rocket.

Stage setting for crewed flights

NASA and the human landing system providers have been working closely together to plan and determine capabilities for the Artemis III mission. With missions fast approaching, both SpaceX and Blue Origin are optimizing hardware availability and capability. SpaceX plans to use the company’s latest version of Starship and basis of the future Starship HLS, called Version 3, while Blue Origin will test their planned HLS crew cabin, allowing each company to apply lessons learned prior to uncrewed and crewed missions on the Moon.

“Each human landing system provider has taken a different approach to the Artemis III mission,” said Steve Creech, program manager, Human Landing System Program, NASA’s Marshall Space Flight Center in Huntsville, Alabama. “Ultimately, SpaceX and Blue Origin have put forward a list of aggressive objectives and goals intended to complement upcoming uncrewed demonstration missions at the Moon so that we can gain both understanding and confidence in the spacecraft and launch vehicles prior to a crewed landing. The lander prototype designs will inform future development efforts and will continue to mature over the next year.”

For the Artemis III mission, the Blue Moon test lander will be based on Blue Origin’s current architecture for its Mark 2 crew lander, incorporating all the major avionics and flight software and control systems to ensure flight operations from this demonstration mission can directly translate to crewed lunar flights. Up to two crew members, donning orange Orion crew survival system suits, will open the hatch to enter the Blue Origin test lander. The production hardware must incorporate many of the same systems and subsystems, including an Environmental Control and Life Support System (ECLSS), a crew cabin, and avionics.

The Blue Origin lander also will fly with an instrumented lunar surface spacesuit mass simulator. Like the suited “Moonikin” manikin that flew aboard Orion during the uncrewed Artemis I test flight, the low-fidelity spacesuit mass simulator will provide real-time feedback about the environment within the Blue Moon crew cabin.

SpaceX’s Starship lander test article will use a Starship Version 3, currently in production and testing, with an added docking system installed on the nose of the 171-foot (52-m) spacecraft, enabling NASA and SpaceX to evaluate how the entire integrated stack of Orion and the Starship test lander interact. NASA and SpaceX are identifying controllability and communications tests for the Artemis III mission. Astronauts will not enter the Starship test lander during Artemis III.

Launch cadence

NASA, SpaceX, and Blue Origin will launch three of the world’s most powerful rockets within a short timeframe of one another, exercising ground processing, launch crews, and facilities as well as control centers, networking, and data exchange at key sites across the country during two separate, back-to-back rendezvous and docking maneuvers between Orion and the lander test articles, before a safe splashdown of the Artemis III crew in Orion.

“Artemis III will be a highly choreographed dance with a demanding launch sequence across multiple launch pads and equally demanding mission operations for our ground and flight crews, making it one of the most complex and ambitious missions NASA has ever undertaken,” said Jeremy Parsons, Artemis program manager. “The demonstration mission will set the stage before our next giant leap. NASA’s expertise in systems engineering and integration, as well as launch and mission operations in low Earth orbit, will bring the mission together.”

For future crewed missions to the Moon, NASA and one of the commercial lander partners will execute a “dual launch campaign,” prepositioning the lander in orbit to await a crewed Orion, launched on SLS. Launching the three rockets in succession of one another for Artemis III offers a unique opportunity to practice launch processing and operations.

Blue Origin’s lander test article is planned to launch first and will be able to loiter in space for up to 30 days, allowing for checkouts in orbit prior to the launch of SLS and Orion from Launch Complex 39B at NASA’s Kennedy Space Center in Florida. The Blue Origin test article will launch at a set trajectory to meet a designated “parking” orbit for these systems checks.

Artemis III will be a highly choreographed dance with a demanding launch sequence across multiple launch pads and equally demanding mission operations for our ground and flight crews, making it one of the most complex and ambitious missions NASA has ever undertaken.

Jeremy Parsons

Artemis program manager

Following the completion of Blue Origin’s rendezvous and docking operations testing  and the Artemis III crewed launch on SLS, SpaceX will launch its Starship lander test article to rendezvous with Orion and its crew for its phase of on-orbit testing.

Throughout the Artemis III mission, Orion will fly in a circular orbit. All three rockets will have more launch opportunities than are available for a lunar mission and will be able to reach the designated mission altitude in a single launch.

Docking operations

During docking and undocking operations, Orion and the Artemis III crew will use the lander test articles as the targets, while Orion will operate as the chaser spacecraft. This is the same configuration planned for future crew landing mission to the Moon.

NASA will ensure both test landers are mission ready and crew safe prior to Artemis III. These verifications will be based on functional and performance requirements for the test lander designs and hazard controls for hardware and software, ensuring the Artemis III astronauts inside Orion are safe throughout both docking phases of the mission.

SpaceX and Blue Origin have already tested their docking capabilities for their respective landers on the ground. SpaceX’s docking capability was qualified in 2023; Blue Origin conducted development ground testing on its pressurized docking system earlier this year.

A key difference between the docking capabilities of both lander test articles will be the location of docking. Orion will dock along the side of the Blue Moon test lander, adjacent to the crew cabin. Later, Orion will dock nose-to-nose with the giant SpaceX test lander.

Software testing between spacecrafts will help demonstrate that the commercial human landing system prototypes and Orion can meet at a precise time and location in space. When Orion docks with the Blue Moon test lander, the Orion spacecraft’s software will control the docked spacecraft. Meanwhile, the SpaceX test article will control the docked spacecraft for the second portion of the mission. During the docking phases, teams with NASA and the commercial partners will be able to test hardware and software interoperability, as well as dynamics of how the integrated lander-Orion spacecraft moves in space.

Through the Artemis program, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

Description

Billions of years ago, an hours-long Martian sandstorm blew so intensely that sand ripples began to climb upon one another as they moved across the surface. These layers of sediment eventually hardened into the multilayered rocks seen in this image, which was taken by NASA’s Curiosity rover on Dec. 12, 2024, the 4,391st Martian day, or sol, of the mission. 

Scientists believe this is the first evidence of climbing wind ripple strata on the Red Planet. Spotted at a location nicknamed “Jawbone Canyon,” these rocks are a rare time capsule preserving a dramatic wind event early in Martian history. A paper detailing the discovery was featured on the cover of the journal Geology on July 1, 2026.

Description

This view looking back up at the outside lip of the 490-foot-tall (150-meter-tall) rim of Jezero Crater was taken by the Mastcam-Z instrument aboard NASA’s Perseverance on May 15, 2025, the 1,505th day, or sol, of the rover’s mission to Mars.  

The bright-colored rocks exposed across the slope, running from middle left to middle right of the image, belong to a formation the science team calls the “Broom Point member,” a 245-foot-thick (75-meter-thick) stack of ancient rock. This sequence of layered bedrock is likely more than 3.9 billion years old, making it among the oldest terrain ever examined by a Mars rover. Evidence uncovered by Perseverance indicates this thick section of rock was built by repeated asteroid strikes, with layers tilting at nearly vertical angles exceeding 80 degrees due to the subsequent colossal impacts that created the Isidis Basin and Jezero Crater.

The rover’s tracks are visible in the image, showing Perseverance’s descent of the steep crater rim slope.

NASA’s Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the “Broom Point member” by the rover’s science team, this sequence of layered bedrock is likely more than 3.9 billion years old, making it among the oldest terrain ever examined by a Mars rover.  

Released Wednesday in the Journal of Geophysical Research: Planets, the findings offer a window into one of the most tumultuous chapters in the history of the solar system.  

“Since leaving Jezero, Perseverance has been exploring a brand-new frontier, both geographically and geologically — a chapter of Martian time that predates the crater itself,” said Ken Farley, Perseverance deputy project scientist at Caltech in Pasadena, California. “On Earth, our earliest geologic history has been fundamentally broken up, deformed, and erased by plate tectonics. Because Mars lacks plate tectonics to recycle its crust, this ancient record remains intact, giving us a rare glimpse into a geological time period that doesn’t exist on our own planet.” 

Reading between layers 

After ascending the western rim of Jezero Crater in late 2024, Perseverance began examining surrounding locations with its science instruments. Their data at Broom Point revealed six distinct rock types, including breccias — rocks composed of angular fragments — alternating with layers of fine-grained, pulverized rock dust. Rock fragments within the breccias are pocked with gas-bubble cavities, indicating they were once molten. 

The presence of tiny, dark, glassy beads within the layers offered an important clue about how these rocks formed. While volcanoes can produce similar glassy droplets, they rarely occur in such high abundance, pointing to asteroid impacts, instead, as the primary architect. In fact, the largest beads rival those flung out by the dinosaur-killing Chicxulub asteroid’s impact on Earth. 

The repetition of these distinct rock types multiple times throughout this thick sequence of rock indicates that high-energy impact events happened again and again across this region of early Mars. 

“The different rock layers are a record of variable-sized impacts occurring at different distances from where this rock sequence was accumulating,” said Alex Jones, a Ph.D. student in planetary geology at Imperial College London and lead author of the paper. “Some large impacts took place very far away, some small impacts nearby. Their debris all ended up landing here, constructing this thick section of rock.”  

How these layers formed may suggest an interaction with water or ice. Several of the layers look like they may have been formed by fast, ground-hugging debris flows. On Earth, these powerful, fluidlike surges can occur when molten rock hits water or ice that instantly flashes into steam.  

Cosmic one-two punch 

Some of Broom Point’s layers tilt at angles exceeding 80 degrees — nearly vertical — which is far too steep to be caused by the impact that created Jezero Crater.  

Instead, scientists suspect a cosmic “one-two punch” shaped this landscape long ago. First, a colossal asteroid impact created the 1,200-mile-wide (1,900-kilometer-wide) Isidis Basin, one of the largest impact basins on Mars, upending and tilting the once-flat rock layers. Later, a second asteroid likely struck, forming Jezero Crater, which measures 28 miles (45 kilometers) across. This second impact fractured and uplifted the already-tilted rocks into the dramatic formations the rover sees today.  

To pin down exactly when these events took place, the Perseverance team collected two core samples, dubbed “Bell Island” and “Main River.” If a future mission were to return them to Earth, laboratory dating could determine when and how often impacts were occurring on early Mars — and, by extension, the infant Earth, whose own early impact record has been erased by billions of years of plate tectonics. 

“During this violent era, it wasn’t rain or snow falling from the sky, but an almost constant barrage of molten rock droplets and pulverized dust kicked up by asteroid impacts,” said Jones. “If we can pin down the ages of these layers, it would be like reading a cosmic weather report from 4 billion years ago.” 

More about Perseverance 

NASA’s Jet Propulsion Laboratory in Southern California, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover on behalf of the agency’s Science Mission Directorate in Washington, as part of NASA’s Mars Exploration Program portfolio. Arizona State University leads the operations of the rover’s Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego, on the design, fabrication, testing, and operation of the cameras. SuperCam is led by Los Alamos National Laboratory in New Mexico, where the instrument’s Body Unit was developed. The rover’s SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument was built at NASA JPL, and its WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera was built at Malin Space Science Systems.

“I didn’t sign up to try to measure a new record or anything”, said Matt Carnicle, a volunteer for the NASA-sponsored Community Collaborative Rain, Hail, and Snow Network, or CoCoRaHS, project. Carnicle measured a whopping 29.06 inches of rainfall on June 18th, 2026, breaking an all-time 24-hour record for the state of Louisiana of 22.00 inches. “I’m just a regular guy who likes to track the weather, and I report what I get in my gauge whether it’s zero, two hundredths, or whatever is in there when I read it.” 

CoCoRaHS  (pronounced KO-ko-rozz) is a network of volunteer weather observers of all ages working together to measure and map rain, hail, and snow by measuring precipitation in their backyards. Together, these thousands of daily precipitation reports – openly available on the project website – are used by scientists and citizens for a wide variety of purposes, to include improving weather forecasting, informing water and land management, driving atmospheric models, and triggering flash flood and severe weather warnings. 

Matt joined through a storm-spotter class where he learned how CoCoRaHS is part of a NASA hail research project focused on Gulf States in the Southeast United States. CoCoRaHS reports (and photos) of hail are used for researching the “melt rate” between when the satellite estimates the stone sizes in the clouds and what volunteers measure on the ground. Matt took it a step further and purchased a standardized rain gauge in order to participate with CoCoRaHS by measuring rainfall.

Matt’s June 18, 2026 rain measurement shatters Louisiana’s 1962 state record of 22.00 inches of rain in 24-hours (Hawaii holds the national record with 49.69 inches in 24-hours). Even more remarkably, the 29.06 inches he measured fell in less than 12 hours! According to Louisiana State Climatologist Jay Grymes, who validated Matt’s measurement along with National Weather Service representatives, an event of this magnitude in this area is expected to happen less than once in a thousand years. A National Oceanic and Atmospheric Administration (NOAA) committee will convene in the coming months to verify and document the new record.

You can join Matt and other CoCoRaHS volunteers and submit official rainfall reports to the National Weather Service. They’re also on the lookout for hail in the southeast, where CoCoRaHS and NASA are doing research on how hail melts as it moves from the clouds to the ground. The only requirement for participation is that volunteers use the correct manual gauge, which is precise to the nearest 1/100th of an inch and is approved by the National Weather Service (measurements from automated rain gauges are not accepted). Sign up here, and you might measure the next record precipitation event: https://science.nasa.gov/citizen-science/community-collaborative-rain-hail-and-snow-network/
