Flight Engineers Give NASA’s Dragonfly Lift
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.”

When NASA's Dragonfly begins full rotorcraft integration and testing in early 2026, the mission team will tap into a trove of data gathered through critical technical trials conducted over the past three years, including, most recently, a testing campaign in at the Transonic Dynamics Tunnel (TDT) Facility at NASA’s Langley Research Center in Hampton, Virginia. NASA/Johns Hopkins APLDragonfly 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.

I Am Artemis: Dave Reynolds
As booster manager for NASA’s SLS (Space Launch System), Dave Reynolds’ path to NASA is embodied by his childhood poster of the space shuttle’s Return to Flight initiative, which hangs in his office, serving as a constant reminder that his journey to the agency began decades ago.
Growing up in Roy, Utah, Reynolds remembers standing outside to watch the billowing smoke rise from booster tests at Northrop Grumman’s Promontory facility. Rockets were the backdrop of his childhood, and growing up during the shuttle missions sparked his fascination for space exploration.
As the booster manager for the SLS, Dave is responsible for the design, development, and flight of the boosters—work that echoes the sense of significance that inspired him as a child to study spaceflight.
“I couldn’t quite verbalize what I felt then, but as I’ve matured over time, I now realize I want to be a part of the team sending astronauts to the Moon, and I have a personal desire to ensure the safety of those individuals,” Reynolds said.
Dave Reynolds, the booster manager for SLS (Space Launch System), works inside the Next Generation Booster Avionics Mockup at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Reynolds is responsible for the design, development, and flight of the boosters for the rocket that carry NASA’s Orion spacecraft and astronauts to the Moon as part of the Artemis II mission. NASA
Early in his career at NASA’s Marshall Space Flight Center in Huntsville, Alabama, Reynolds worked on the J-2X — a liquid-cryogenic engine that was once slated as a candidate to power the SLS upper stage. In 2012, he made a jump to solid rocket motors when he became the subsystem manager for the SLS boosters office. Reynolds spent his days managing and testing motor cases, seals, igniters, and separation motors.
He was promoted to deputy manager for the SLS office where he helped oversee development of the solid rocket boosters. He also was given the task of developing and managing the evolved composite boosters that would be used for future Artemis missions.
With the launch of Artemis II on the horizon, Reynolds is thrilled to be part of the team preparing to send a crew of four astronauts around the Moon.
Deep down, I’m really excited about Artemis II. The eight-year-old me is still in there, eager to watch the smoke rising from those booster tests at a distance. He wouldn’t believe the things I’ve seen and what I’m about to see.Dave Reynolds

“Deep down, I’m really excited about Artemis II. The eight-year-old me is still in there, eager to watch the smoke rising from those booster tests at a distance. He wouldn’t believe the things I’ve seen and what I’m about to see,” Reynolds said.
Reynolds witnessed moments that would have stunned his eight-year-old self. In 2022, he watched as the SLS illuminated the morning sky during the launch of Artemis I. More recently, the evolved booster he helped develop performed its first full-scale test. Reynolds watched as the booster roared to life – just miles from his hometown in Utah.

Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars. NASA
From his driveway to the test site, Reynolds’ curiosity grew into a career shaped by purpose, responsibility, and respect for the work ahead. The poster hanging on Reynolds’ wall isn’t just a souvenir from the past – it’s a reminder of where his interest took root and how far that curiosity has carried him.
As the team moves closer to the launch of Artemis II which will take astronauts around the Moon, Reynolds feels a familiar sense of exhilaration. The questions that once drew him toward space are still guiding him today, except this time he is one of the individuals helping to shape the answers.

NASA’s Pandora Satellite, CubeSats to Explore Exoplanets, Beyond

NASA’s Pandora Satellite, CubeSats to Explore Exoplanets, BeyondEditor’s Note, Jan. 11, 2026: NASA’s Pandora and the NASA-sponsored BlackCAT and SPARCS missions lifted off at 8:44 a.m. EST (5:44 a.m. PST) Sunday, Jan. 11.
A new NASA spacecraft called Pandora is awaiting launch ahead of its journey to study the atmospheres of exoplanets, or worlds beyond our solar system, and their stars.
Along for the ride are two shoebox-sized satellites called BlackCAT (Black Hole Coded Aperture Telescope) and SPARCS (Star-Planet Activity Research CubeSat), as NASA innovates with ambitious science missions that take low-cost, creative approaches to answering questions like, “How does the universe work?” and “Are we alone?”
All three missions are set to launch Jan. 11 on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California. The launch window opens at 8:19 a.m. EST (5:19 a.m. PST). SpaceX will livestream the event.

“Pandora’s goal is to disentangle the atmospheric signals of planets and stars using visible and near-infrared light,” said Elisa Quintana, Pandora’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This information can help astronomers determine if detected elements and compounds are coming from the star or the planet — an important step as we search for signs of life in the cosmos.”
BlackCAT and SPARCS are small satellites that will study the transient, high-energy universe and the activity of low-mass stars, respectively.
Pandora will observe planets as they pass in front of their stars as seen from our perspective, events called transits.
As starlight passes through a planet’s atmosphere, it interacts with substances like water and oxygen that absorb characteristic wavelengths, adding their chemical fingerprints to the signal.
But while only a small fraction of the star’s light grazes the planet, telescopes also collect the rest of the light emitted by the star’s facing side. Stellar surfaces can sport brighter and darker regions that grow, shrink, and change position over time, suppressing or magnifying signals from planetary atmospheres. Adding a further complication, some of these areas may contain the same chemicals that astronomers hope to find in the planet’s atmosphere, such as water vapor.
All these factors make it difficult to be certain that important detected molecules come from the planet alone.
Pandora will help address this problem by providing in-depth study of at least 20 exoplanets and their host stars during its initial year. The satellite will look at each planet and its star 10 times, with each observation lasting a total of 24 hours. Many of these worlds are among the over 6,000 discovered by missions like NASA’s TESS (Transiting Exoplanet Survey Satellite).
This view of the fully integrated Pandora spacecraft was taken May 19, 2025, following the mission’s successful environmental test campaign at Blue Canyon Technologies in Lafayette, Colorado. Visible are star trackers (center), multilayer insulation blankets (white), the end of the telescope (top), and the solar panel (right) in its launch configuration. NASA/BCT
Pandora will collect visible and near-infrared light using a novel, all-aluminum 17-inch-wide (45-centimeter) telescope jointly developed by Lawrence Livermore National Laboratory in California and Corning Incorporated in Keene, New Hampshire. Pandora’s near-infrared detector is a spare developed for NASA’s James Webb Space Telescope.
Each long observation period will capture a star’s light both before and during a transit and help determine how stellar surface features impact measurements.
“These intense studies of individual systems are difficult to schedule on high-demand missions, like Webb,” said engineer Jordan Karburn, Pandora’s deputy project manager at Livermore. “You also need the simultaneous multiwavelength measurements to pick out the star’s signal from the planet’s. The long stares with both detectors are critical for tracing the exact origins of elements and compounds scientists consider indicators of potential habitability.”
Pandora is the first satellite to launch in the agency’s Astrophysics Pioneers program, which seeks to do compelling astrophysics at a lower cost while training the next generation of leaders in space science.
After launching into low Earth orbit, Pandora will undergo a month of commissioning before embarking on its one-year prime mission. All the mission’s data will be publicly available.
“The Pandora mission is a bold new chapter in exoplanet exploration,” said Daniel Apai, an astronomy and planetary science professor at the University of Arizona in Tucson where the mission’s operations center resides. “It is the first space telescope built specifically to study, in detail, starlight filtered through exoplanet atmospheres. Pandora’s data will help scientists interpret observations from past and current missions like NASA’s Kepler and Webb space telescopes. And it will guide future projects in their search for habitable worlds.”

The BlackCAT and SPARCS missions will take off alongside Pandora through NASA’s Astrophysics CubeSat program, the latter supported by the Agency’s CubeSat Launch Initiative.
CubeSats are a class of nanosatellites that come in sizes that are multiples of a standard cube measuring 3.9 inches (10 centimeters) across. Both BlackCAT and SPARCS are 11.8 by 7.8 by 3.9 inches (30 by 20 by 10 centimeters). CubeSats are designed to provide cost-effective access to space to test new technologies and educate early career scientists and engineers while delivering compelling science.
The BlackCAT mission will use a wide-field telescope and a novel type of X-ray detector to study powerful cosmic explosions like gamma-ray bursts, particularly those from the early universe, and other fleeting cosmic events. It will join NASA’s network of missions that watch for these changes. Abe Falcone at Pennsylvania State University in University Park, where the satellite was designed and built, leads the mission with contributions from Los Alamos National Laboratory in New Mexico. Kongsberg NanoAvionics US provided the spacecraft bus.
The SPARCS CubeSat will monitor flares and other activity from low-mass stars using ultraviolet light to determine how they affect the space environment around orbiting planets. Evgenya Shkolnik at Arizona State University in Tempe leads the mission with participation from NASA’s Jet Propulsion Laboratory in Southern California. In addition to providing science support, JPL developed the ultraviolet detectors and the associated electronics. Blue Canyon Technologies fabricated the spacecraft bus.
Pandora is led by NASA Goddard. Livermore provides the mission’s project management and engineering. Pandora’s telescope was manufactured by Corning and developed collaboratively with Livermore, which also developed the imaging detector assemblies, the mission’s control electronics, and all supporting thermal and mechanical subsystems. The near-infrared sensor was provided by NASA Goddard. Blue Canyon Technologies provided the bus and performed spacecraft assembly, integration, and environmental testing. NASA’s Ames Research Center in California’s Silicon Valley will perform the mission’s data processing. Pandora’s mission operations center is located at the University of Arizona, and a host of additional universities support the science team.
