In sending a car-sized rotorcraft to explore Saturn’s moon Titan, NASA’s Dragonfly mission will undertake an unprecedented voyage of scientific discovery. And the work to ensure that this first-of-its-kind project can fulfill its ambitious exploration vision is underway in some of the nation’s most advanced space simulation and testing laboratories.

Set for launch in in 2028, the Dragonfly rotorcraft is being designed and built at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, with contributions from organizations around the world. On arrival in 2034, Dragonfly will exploit Titan’s dense atmosphere and low gravity to fly to dozens of locations, exploring varied environments from organic equatorial dunes to an impact crater where liquid water and complex organic materials essential to life (at least as we know it) may have existed together.

Aerodynamic testing

When full rotorcraft integration and testing begins in February, the team will tap into a trove of data gathered through critical technical trials conducted over the past three years, including, most recently, two campaigns at the Transonic Dynamics Tunnel (TDT) facility at NASA’s Langley Research Center in Hampton, Virginia.

The TDT is a versatile 16-foot-high, 16-foot-wide, 20-foot-long testing hub that has hosted studies for NASA, the Department of War, the aircraft industry and an array of universities.

Over five weeks, from August into September, the team evaluated the performance of Dragonfly’s rotor system – which provides the lift for the lander to fly and enables it to maneuver – in Titan-like conditions, looking at aeromechanical performance factors such as stress on the rotor arms, and effects of vibration on the rotor blades and lander body. In late December, the team also wrapped up a set of aerodynamics tests on smaller-scale Dragonfly rotor models in the TDT.

“When Dragonfly enters the atmosphere at Titan and parachutes deploy after the heat shield does its job, the rotors are going to have to work perfectly the first time,” said Dave Piatak, branch chief for aeroelasticity at NASA Langley. “There’s no room for error, so any concerns with vehicle structural dynamics or aerodynamics need to be known now and tested on the ground. With the Transonic Dynamics Tunnel here at Langley, NASA offers just the right capability for the Dragonfly team to gather this critical data.”

Critical parts

In his three years as an experimental machinist at APL, Cory Pennington has crafted parts for projects dispatched around the globe. But fashioning rotors for a drone to explore another world in our solar system? That was new – and a little daunting.

“The rotors are some of the most important parts on Dragonfly,” Pennington said. “Without the rotors, it doesn’t fly – and it doesn’t meet its mission objectives at Titan.”

Pennington and team cut Dragonfly’s first rotors on Nov. 1, 2024. They refined the process as they went: starting with waterjet paring of 1,000-pound aluminum blocks, followed by rough machining, cover fitting, vent-hole drilling and hole-threading. After an inspection, the parts were cleaned, sent out for welding and returned for final finishing.

“We didn’t have time or materials to make test parts or extras, so every cut had to be right the first time,” Pennington said, adding that the team also had to find special tools and equipment to accommodate some material changes and design tweaks.

The team was able to deliver the parts a month early. Engineers set up and spin-tested the rotors at APL – attached to a full-scale model representing half of the Dragonfly lander – before transporting the entire package to the TDT at NASA Langley in late July.

“On Titan, we’ll control the speeds of Dragonfly’s different rotors to induce forward flight, climbs, descents and turns,” said Felipe Ruiz, lead Dragonfly rotor engineer at APL.

“It’s a complicated geometry going to a flight environment that we are still learning about. So the wind tunnel tests are one of the most important venues for us to demonstrate the design.”

And the rotors passed the tests.

“Not only did the tests validate the design team’s approach, we’ll use all that data to create high-fidelity representations of loads, forces and dynamics that help us predict Dragonfly’s performance on Titan with a high degree of confidence,” said Rick Heisler, wind tunnel test lead from APL.

Next, the rotors will undergo fatigue and cryogenic trials under simulated Titan conditions, where the temperature is minus 290 degrees Fahrenheit (minus 178 degrees Celsius), before building the actual flight rotors.

“We’re not just cutting metal — we’re fabricating something that’s going to another world,” Pennington said. “It’s incredible to know that what we build will fly on Titan.”

Collaboration, innovation

Elizabeth “Zibi” Turtle, Dragonfly principal investigator at APL, says the latest work in the TDT demonstrates the mission’s innovation, ingenuity and collaboration across government and industry.

“The team worked well together, under time pressure, to develop solutions, assess design decisions, and execute fabrication and testing,” she said. “There’s still much to do between now and our launch in 2028, but everyone who worked on this should take tremendous pride in these accomplishments that make it possible for Dragonfly to fly on Titan.”

Dragonfly has been a collaborative effort from the start. Kenneth Hibbard, mission systems engineer from APL, cites the vertical-lift expertise of Penn State University on the initial rotor design, aero-related modeling and analysis, and testing support in the TDT, as well as NASA Langley’s 14-by-22-foot Subsonic Tunnel. Sikorsky Aircraft of Connecticut has also supported aeromechanics and aerodynamics testing and analysis, as well as flight hardware modeling and simulation.

The Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, leads the Dragonfly mission for NASA in collaboration with several NASA centers, industry partners, academic institutions and international space agencies. Elizabeth “Zibi” Turtle of APL is the principal investigator. Dragonfly is part of NASA’s New Frontiers Program, managed by the Planetary Missions Program Office at NASA Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

Jupiter beams bright, Saturn and the Moon cozy up, and the Beehive Cluster appears

Jupiter is at its biggest and brightest all year, the Moon and Saturn pair up, and the Beehive Cluster buzzes into view.

Skywatching Highlights

• Jan. 10: Jupiter at opposition
• Jan. 23: Saturn and Moon conjunction
• Jan. (throughout): Beehive Cluster

Transcript

Jupiter is at its biggest and brightest

The Moon and Saturn share the sky 

And the beehive cluster makes an appearance 

That’s what’s up, this January

January 10, Jupiter will be at its most brilliant of the entire year! 

This night, Jupiter will be at what’s called “opposition,” meaning that Earth will be directly between Jupiter and the Sun. 

In this alignment, Jupiter will appear bigger and brighter in the night sky than it will all year – talk about starting off the new year bright! 

To see Jupiter at its best this year, look to the east and all evening long, you’ll be able to see the planet in the constellation Gemini. It will be one of the brightest objects in the night sky (only the moon and Venus will be brighter)  

Saturn and the Moon will share the sky on January 23rd as part of a conjunction!  

A conjunction is when objects in the sky look close together even though they’re actually far apart. 

To spot the pair, look to the west and you’ll see Saturn just below the moon, sparkling in the night sky. 

The beehive cluster will be visible in the night sky throughout January!

The beehive cluster, more formally known as Messier 44, or M44, is made of at least 1,000 stars

It’s an open star cluster, meaning it’s a loosely-bound group of stars. There are thousands of open star clusters like the beehive in the Milky Way Galaxy! 

To see the beehive cluster, look to the eastern night sky after sunset and before midnight throughout the month – especially great nights to spot the cluster are around the middle of January when the cluster isn’t too high or low in the sky to see.   

With dark skies you might be able to spot the beehive with just your eyes, but binoculars or a small telescope will help. 

Here are the phases of the Moon for January.

What’s Up

Galaxies

Stars

After nearly five years on Mars, NASA’s Perseverance rover has traveled almost 25 miles (40 kilometers), and the mission team has been busy testing the rover’s durability and gathering new science findings on the way to a new region nicknamed “Lac de Charmes,” where it will be searching for rocks to sample in the coming year.

Like its predecessor Curiosity, which has been exploring a different region of Mars since 2012, Perseverance was made for the long haul. NASA’s Jet Propulsion Laboratory in Southern California, which built Perseverance and leads the mission, has continued testing the rover’s parts here on Earth to make sure the six-wheeled scientist will be strong for years to come. This past summer, JPL certified that the rotary actuators that turn the rover’s wheels can perform optimally for at least another 37 miles (60 kilometers); comparable brake testing is underway as well.

Over the past two years, engineers have extensively evaluated nearly all the vehicle’s subsystems in this way, concluding that they can operate until at least 2031.

“These tests show the rover is in excellent shape,” said Perseverance’s deputy project manager, Steve Lee of JPL, who presented the results on Wednesday at the American Geophysical Union’s annual meeting, the largest gathering of planetary scientists in the United States. “All the systems are fully capable of supporting a very long-term mission to extensively explore this fascinating region of Mars.”

Perseverance has been driving through Mars’ Jezero Crater, the site of an ancient lake and river system, where it has been collecting scientifically compelling rock core samples. In fact, in September, the team announced that a sample from a rock nicknamed “Cheyava Falls” contains a potential fingerprint of past microbial life.

More efficient roving

In addition to a hefty suite of six science instruments, Perseverance packs more autonomous capabilities than past rovers. A paper published recently in IEEE Transactions on Field Robotics highlights an autonomous planning tool called Enhanced Autonomous Navigation, or ENav. The software looks up to 50 feet (15 meters) ahead for potential hazards, then chooses a path without obstacles and tells Perseverance’s wheels how to steer there.

Engineers at JPL meticulously plan each day of the rover’s activities on Mars. But once the rover starts driving, it’s on its own and sometimes has to react to unexpected obstacles in the terrain. Past rovers could do this to some degree, but not if these obstacles were clustered near each other. They also couldn’t react as far in advance, resulting in the vehicles driving slower while approaching sand pits, rocks, and ledges. In contrast, ENav’s algorithm evaluates each rover wheel independently against the elevation of terrain, trade-offs between different routes, and “keep-in” or “keep-out” areas marked by human operators for the path ahead.

“More than 90% of Perseverance’s journey has relied on autonomous driving, making it possible to quickly collect a diverse range of samples,” said JPL autonomy researcher Hiro Ono, a paper lead author. “As humans go to the Moon and even Mars in the future, long-range autonomous driving will become more critical to exploring these worlds.”

New science

A paper published Wednesday in Science details what Perseverance discovered in the “Margin Unit,” a geologic area at the margin, or inner edge, of Jezero Crater. The rover collected three samples from that region. Scientists think these samples may be particularly useful for showing how ancient rocks from Mars’ deep interior interacted with water and the atmosphere, helping create conditions supportive for life.

From September 2023 to November 2024, Perseverance ascended 1,312 feet (400 meters) of the Margin Unit, studying rocks along the way — especially those containing the mineral olivine. Scientists use minerals as timekeepers because crystals within them can record details about the precise moment and conditions in which they formed.

Jezero Crater and the surrounding area holds large reserves of olivine, which forms at high temperatures, typically deep within a planet, and offers a snapshot of what was going on in the planet’s interior. Scientists think the Margin Unit’s olivine was made in an intrusion, a process where magma pushes into underground layers and cools into igneous rock. In this case, erosion later exposed that rock to the surface, where it could interact with water from the crater’s ancient lake and carbon dioxide, which was abundant in the planet’s early atmosphere.

Those interactions form new minerals called carbonates, which can preserve signs of past life, along with clues as to how Mars’ atmosphere changed over time.

“This combination of olivine and carbonate was a major factor in the choice to land at Jezero Crater,” said the new paper’s lead author, Perseverance science team member Ken Williford of Blue Marble Space Institute of Science in Seattle. “These minerals are powerful recorders of planetary evolution and the potential for life.”

Together, the olivine and carbonates record the interplay between rock, water, and atmosphere inside the crater, including how each changed over time. The Margin Unit’s olivine appeared to have been altered by water at the base of the unit, where it would have been submerged. But the higher Perseverance went, the more the olivine bore textures associated with magma chambers, like crystallization, and fewer signs of water alteration.

As Perseverance leaves the Margin Unit behind for Lac de Charmes, the team will have the chance to collect new olivine-rich samples and compare the differences between the two areas.

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.

Technological and scientific steps toward humanity’s next giant leap on the Red Planet include:

• Launched a pair of spacecraft, known as ESCAPADE, on a mission to Mars, arriving in September 2027, to study how its magnetic environment is impacted by the Sun. 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. 

• New nations joining America, a founding member in 2020, in signing the accords this year included Bangladesh, Finland, Norway, and Senegal, as well as Hungary, Malaysia, and the Philippines.
• A NASA delegation participated in the 76th International Astronautical Congress in Sydney, Australia. During the congress, NASA co-chaired the Artemis Accords Principals’ Meeting, bringing together dozens of nations furthering discussions on their implementation. 

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.

Astrobiology

• A Perseverance sample found on Mars potentially contain biosignatures, a substance or structure that might have a biological origin but requires additional data and studying before any conclusions can be reached about the absence or presence of life.
• NASA’s Curiosity rover on Mars found the largest organic compounds on the Red Planet to date.
• Teams also are working to develop technologies for the Habitable Worlds Observatory, and the agency now has tallied 6,000 exoplanets.
• Samples from asteroid Bennu revealed sugars, amino acids, and other life-building molecules.

Planetary Defense

• In defense of Earth and protecting humanity, NASA has continued to monitor a near-Earth object that triggered potential impact notifications.
• Scientists have worked to calculate more precise impact models, noting the asteroid, which poses no significant threat to Earth, has only a 0.0004% chance of hitting our planet. An international satellite determined NASA’s DART (Double Asteroid Redirect Test) released 35.5 million pounds of dust and rock from the mission’s impact in 2022.
• Other data collection and missions helped inform knowledge of geomagnetic storms, flooding in Texas, tsunami waves in real-time, improved hurricane forecasting and ocean monitoring, high-resolution water resources for farmers and ranchers, and more.
• NASA also advanced wildfire detection, improved lunar reflectance calibration, and studied heat-trapping processes. 

Heliophysics

• In addition to the ESCAPADE mission, NASA also launched five other heliophysics missions to study the Sun and space weather, including PUNCH, EZIE, TRACERS, IMAP, and the Carruthers Geocorona Observatory. 

In addition to launching the NISAR mission, here are other key science moments:

• Completion of NASA’s next flagship observatory, the Nancy Grace Roman Space Telescope, is done, with final testing underway. The telescope will help answer questions about dark energy and exoplanets and will be ready to launch as early as fall of 2026.
• The agency’s newest operating flagship telescope, James Webb Space Telescope, now in its third year, continued to transform our understanding of the universe, and Hubble celebrated its 35th year with a 2.5-gigapixel Andromeda galaxy mosaic.
• Juno found a massive, hyper-energetic volcano on Jupiter’s moon Io.
• NASA’s Parker Solar Probe team shared new images of the Sun’s atmosphere, taken closer to the star than ever captured before.
• Lucy completed a successful rehearsal flyby of the asteroid Donaldjohanson.
• The agency’s SPHEREx space telescope is creating the first full-sky map in 102 infrared colors.
• NASA space telescopes including Chandra X-ray Observatory, IXPE, Fermi, Swift, and NuSTAR continued to reveal secrets in the universe from record-setting black holes to the first observations of the cosmos’ most magnetic objects.

25 years of continuous presence in low Earth orbit

In 2025, the International Space Station celebrated 25 years of continuous human presence, a milestone achievement underscoring its role as a beacon of global cooperation in space. The orbital laboratory supported thousands of hours of groundbreaking research in microgravity in 2025, advancing commercial space development and preparing for future human exploration of the Moon and Mars.

• For the first time, all eight docking ports were occupied by visiting spacecraft to close out the year, demonstrating the strength of NASA’s commercial and international partnerships. Twenty-five people from six countries lived and worked aboard the station this year. In all, 12 spacecraft visited the space station in 2025, including seven cargo missions delivering more than 50,000 pounds of science, tools, and critical supplies to the orbital complex.  

Research aboard the International Space Station continues to benefit life on Earth and support deep space exploration.

• Several studies with Crew-10 and Crew 11 aimed at understanding how the human body adapts to spaceflight, including a new study to assess astronauts’ performance, decision making, and piloting capabilities during simulated lunar landings. 
• In September, the U.S. Food and Drug Administration approved an early-stage cancer treatment, supported by research aboard the space station, that could reduce costs and shorten treatment times for patients.
• Scientists also published findings in peer-reviewed journals on topics such as astronaut piloting performance after long missions, the use of biologically derived materials to shield against space radiation, robotic telesurgery in space, and how spaceflight affects stem cells, all advancing our understanding of human physiology in space and on Earth.
• Researchers 3D-printed medical implants with potential to support nerve repair; advanced work toward large-scale, in-space semiconductor manufacturing; and researched the production of medical components with increased stability and biocompatibility that could improve medication delivery.

Additional notable space operations accomplishments included:

• NASA’s SpaceX Crew-9 astronauts Nick Hague, Suni Williams, and Butch Wilmore returned in March after a long-duration mission, including more than eight months for Williams and Wilmore. The trio completed more than 150 scientific experiments and 900 hours of research during the stay aboard the orbiting laboratory. Williams also conducted two spacewalks, setting a new female spacewalking record with 62 hours, 6 minutes, and ranking her fourth all-time in spacewalk duration. 
• NASA astronaut Don Pettit returned in April with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner, concluding a seven-month mission. Pettit, who turned 70 the day of his return, completed 400 hours of research during his flight, and has now logged 590 days in space across four missions. 
• SpaceX Dragon cargo missions 32 and 33 launched in April and August, delivering more than 11,700 pounds of cargo, while SpaceX 33 tested a new capability to help maintain the altitude of station.  
• Axiom Mission 4, the fourth private astronaut mission to the space station, concluded in July, furthering NASA’s efforts to support and advance commercial operations in low Earth orbit. 
• NASA SpaceX Crew-11 mission launched in August with NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov aboard. The crew remains aboard the space station where they are conducting long-duration research to support deep space exploration and benefit life on Earth. 
• NASA’s SpaceX Crew-10 mission completed more than 600 hours of research before returning in August, when they became the first crewed SpaceX mission for NASA to splash down in the Pacific Ocean.  
• In September, the first Northrop Grumman Cygnus XL spacecraft arrived, delivering more than 11,000 pounds of cargo, including research supporting Artemis and Mars exploration. 
• NASA Glenn researchers tested handheld X-ray devices that could help astronauts quickly check for injuries or equipment problems during future space missions. 
• For nearly six years, NASA’s BioNutrients project has studied how to produce essential nutrients to support astronaut health during deep space missions, where food and vitamins have limited shelf lives. With its third experiment now aboard the International Space Station, the research continues to advance preparations for long-duration spaceflight.
• NASA astronaut Chris Williams arrived with Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev for an eight-month science mission aboard the station. Following their arrival, NASA astronaut Jonny Kim returned home, concluding his own eight-month mission. 

NASA has worked with commercial companies to advance development of privately owned and operated space stations in low Earth orbit from which the agency, along with other customers, can purchase services and stimulate the growth of commercial activities in microgravity. This work is done in advance of the International Space Station’s retirement in 2030.

Among the many achievements made by our partners, recent advancements include:

• Axiom Space has completed critical design review, machining activities, and the final welds, moving to testing for the primary structure of Axiom Station’s first module.
• Starlab completed five development and design milestones focused on reviews of its preliminary design and safety, as well as spacecraft mockup and procurement plans.
• Completed testing of the trace contaminant control system for Vast’s Haven-1 space station using facilities at NASA Marshall, confirming the system can maintain a safe and healthy atmosphere.
• Blue Origin’s Orbital Reef completed a human-in-the-loop testing milestone using individual participants or small groups to perform day-in-the-life walkthroughs in life-sized mockups of major station components. 
• The agency also continues to support the design and development of space stations and technologies through agreements with Northrop Grumman, Sierra Space, SpaceX, Special Aerospace Services, and ThinkOrbital.

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: 

• Conducted live flight testing with aircraft performing simulated wildland fire response using NASA’s new portable airspace management system known as Advanced Capabilities for Emergency Response Operations (ACERO) project. 
• Used NASA’s Transonic Dynamics Tunnel in Virginia to test the performance of rotors designed for NASA’s Dragonfly rotorcraft, which will explore Saturn’s moon, Titan. 
• Performed wind tunnel tests to see how icing could affect longer, thinner wings on future airliners and to evaluate a tiltwing design likely to see wide usage in advanced air mobility vehicles. 
• Tested NASA-designed ultralight aerogel antennas that could be embedded into aircraft skin for more aerodynamic, reliable, satellite communications. 
• Worked to advance the airborne transportation of people and goods, including a collaboration with the Department of War to advance capabilities for long-distance cargo drones; a partnership to test a tool for remotely piloted urban air transportation; flight tests with partners exploring large-scale drone cargo flights; and work with ResilienX to enhance preflight planning for safer future skies. 
• Performed research to help with the integration of air taxis and similar future aircraft, such as producing real-world data to help understand their flight dynamics; dropping a full-scale fuselage model to test its materials upon impact; collecting to evaluate strategies for urban airspace integration; investigating passenger comfort; and testing 5G-based aviation network technology to boost air taxi connectivity. Evaluated a system that would help prevent collisions between air taxis and other future aircraft in urban environments.  
• Made advances to unsteady pressure sensitive paint wind tunnel technology, allowing it to measure air pressure on miniature aircraft and rocket models 10,000 times faster with 1,000 times higher resolution. 
• Collected data on mixed reality systems that allow users to interact with physical flight simulators while wearing virtual reality headsets.  
• Developed the GlennICE tool for U.S. researchers and aircraft developers to integrate icing-related considerations into aircraft design. 
• Supported research for safer and smoother airline and airport operations, including; developing a preflight rerouting tool to actively curb commercial airline delays and save fuel; demonstrating a unique air traffic management concept for safer aircraft operate at higher altitudes; and hosting technology testing to make runway taxiing safer and more efficient.
• Adapted technology that can measure temperature and strain on high-speed air vehicles for hypersonic flights at speeds greater than Mach 5. 
• Provided funding for 14 university teams to build innovative new compact emergency response aircraft; issued new awards for university teams to participate in real-world aviation challenges, including the program’s first to a community college. NASA also named winners in the 2025 Gateways to Blue Skies competition, as well as selected new student teams for the University Leadership Initiative. 

Technologies that advance exploration, support growing space economies

From spinoff technologies on Earth to accelerating development of technologies in low Earth orbit and at the Moon and Mars, NASA develops, demonstrates, and transfer new space technologies that benefit the agency, private companies, and other government agencies and missions.

Accomplishments by NASA and our partners in 2025 included:
