Dual Propulsion Experiment (DUPLEX) deploys from the International Space Station December 2, 2025.
NASA
NASA is working with commercial partners to create high-performing, reliable propulsion systems that will help small spacecraft safely maneuver in orbit, reach intended destinations across the solar system, and accomplish mission operations.
Two new micropropulsion technologies are being tested in space onboard a CubeSat called DUPLEX (Dual Propulsion Experiment) that deployed into low Earth orbit from the International Space Station on Dec. 2. The CubeSat is fitted with two thruster systems that use spools of polymer fibers to provide performance levels of propulsion comparable to existing systems but with greater safety during assembly and more affordability.
One of the propulsion technologies is a fiber-fed pulsed plasma thruster system which employs an electric pulse to vaporize Teflon material and uses the resulting ions to deliver strong, efficient thrust while using very little fuel. The other propulsion technology is a monofilament vaporization propulsion system – inspired by 3D printers – which heats and vaporizes a common polymer material known as Delrin to create continuous thrust.
On orbit, DUPLEX will test its advanced propulsion systems by raising and lowering its orbit over two years, demonstrating the systems’ capabilities to maintain a vehicle’s orbit over time. Micropropulsion solutions enable a variety of cost-efficient capabilities necessary for operators in a bustling low Earth orbit economy, including maintaining and adjusting orbits to avoid debris or nearby spacecraft, and coordinating maneuvers between spacecraft to perform maintenance, inspections, and other critical activities. The systems tested on DUPLEX can also make spacecraft capable of lower cost extended missions in areas that are farther from Earth, such as the Moon and Mars.
Technologies like those demonstrated onboard DUPLEX open the door for U.S. industry to provide efficient, affordable spacecraft systems for various space-based applications, building a stronger orbital economy to meet the needs of NASA and the nation.
The DUPLEX spacecraft was developed by Champaign-Urbana Aerospace in Illinois. NASA’s Small Spacecraft and Distributed Systems program at the agency’s Ames Research Center in California’s Silicon Valley supported the development, with funding from the Small Business Innovation Research program and a 2019 Tipping Point industry partnership award through the agency’s Space Technology Mission Directorate.

Picture this: You’re just about done with a transoceanic flight, and the tracker in your seat-back screen shows you approaching your destination airport. And then … you notice your plane is moving away. Pretty far away. You approach again and again, only to realize you’re on a long, circling loop that can last an hour or more before you land.
If this sounds familiar, there’s a good chance the delay was caused by issues with trajectory prediction. Your plane changed its course, perhaps altering its altitude or path to avoid weather or turbulence, and as a result its predicted arrival time was thrown off.
“Often, if there’s a change in your trajectory – you’re arriving slightly early, you’re arriving slightly late – you can get stuck in this really long, rotational holding pattern,” said Shivanjli Sharma, NASA’s Air Traffic Management–eXploration (ATM-X) project manager and the agency’s Ames Research Center in California’s Silicon Valley.
This inconvenience to travelers is also an economic and efficiency challenge for the aviation sector, which is why NASA has worked for years to study the issue, and recently teamed with Boeing to conduct real-time tests an advanced system that shares trajectory data between an aircraft and its support systems.
Boeing began flying a United Airlines 737 for about two weeks in October testing a data communication system designed to improve information flow between the flight deck, air traffic control, and airline operation centers. The work involved several domestic flights based in Houston, as well as flight over the Atlantic to Edinburgh, Scotland.
This partnership has allowed NASA to further its commitment to transformational aviation research.

The testing was Boeing’s most recent ecoDemonstrator Explorer program, through which the company works with public and private partners to accelerate aviation innovations. This year’s ecoDemonstrator flight partners included NASA, the Federal Aviation Administration, United Airlines, and several aerospace companies as well as academic and government researchers.
NASA’s work in the testing involved the development of an oceanic trajectory prediction service – a system for sharing and updating trajectory information, even over a long, transoceanic flight that involves crossing over from U.S. air traffic systems into those of another country. The collaboration allowed NASA to get a more accurate look at what’s required to reduce gaps in data sharing.
“At what rate do you need these updates in an oceanic environment?” Sharma said. “What information do you need from the aircraft? Having the most accurate trajectory information will allow aircraft to move more efficiently around the globe.”
Boeing and the ecoDemonstrator collaborators plan to use the flight data to move the data communication system toward operational service. The work has allowed NASA to continue its work to improve trajectory prediction, and through its connection with partners, put its research into practical use as quickly as possible.
“This partnership has allowed NASA to further its commitment to transformational aviation research,” Sharma said. “Bringing our expertise in trajectory prediction together with the contributions of so many innovative partners contributes to global aviation efficiency that will yield real benefits for travelers and industry.”
NASA ATM-X’s part in the collaboration falls under the agency’s Airspace Operations and Safety Program, which works to enable safe, efficient aviation transportation operations that benefit the flying public and industry. The work is supported through NASA’s Aeronautics Research Mission Directorate.

NASA is helping shape the future of urban air travel with a new simulation that will manage how electric air taxis and drones can successfully operate within busy areas.
The demonstration, held at NASA’s Ames Research Center in California’s Silicon Valley earlier this year, focused on a system called the Strategic Deconfliction Simulation, which helps coordinate flight plans before takeoff, reducing the risk of conflicts in busy urban environments
At the event, researchers demonstrated NASA’s Situational Viewer and Demand-Capacity Balancing Monitor, which visualizes air traffic and adjusts flight plans in real time. The simulation demonstrated traffic scenarios involving drone operations throughout the Dallas-Fort Worth area, testing how preplanned flights could improve congestion and manage the demand and capacity of the airspace – ensuring that all aircraft can operate smoothly even in crowded conditions.
Working with industry partners is critical to NASA’s efforts to develop and refine technologies needed for future air mobility. During the simulation, the company, ANRA Technologies, demonstrated its fleet and vertiport management systems, which are designed to support the coordination of multiple aircraft and ground operations.
“Simulating these complex environments supports broader efforts to ensure safe integration of drones and other advanced vehicles into the US airspace,” said Hanbong Lee, engineer at NASA Ames. “By showcasing these capabilities, we’re delivering critical data and lessons learned to support efforts at NASA and industry.”
This demonstration is another step toward the NASA team’s plan to hold a technical capability level simulation in 2026. This upcoming simulation would help shape the development of services aimed at managing aircraft flying in urban areas.
The simulation was created through a NASA team from its Air Mobility Pathfinders project, part of the agency’s continuing work to find solutions for safely integrating innovative new aircraft such as air taxis into U.S. cities and the national airspace. By developing advanced evaluations and simulations, the project supports safe, scalable, and publicly trusted air travel in urban areas, paving the way for a future where air taxis and drones are a safe and reliable part of everyday life.
The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft, three new papers published Tuesday by the journals Nature Geosciences and Nature Astronomy present remarkable discoveries: sugars essential for biology, a gum-like substance not seen before in astromaterials, and an unexpectedly high abundance of dust produced by supernova explosions.
Sugars essential to life
Scientists led by Yoshihiro Furukawa of Tohoku University in Japan found sugars essential for biology on Earth in the Bennu samples, detailing their findings in the journal Nature Geoscience. The five-carbon sugar ribose and, for the first time in an extraterrestrial sample, six-carbon glucose were found. Although these sugars are not evidence of life, their detection, along with previous detections of amino acids, nucleobases, and carboxylic acids in Bennu samples, show building blocks of biological molecules were widespread throughout the solar system.
For life on Earth, the sugars deoxyribose and ribose are key building blocks of DNA and RNA, respectively. DNA is the primary carrier of genetic information in cells. RNA performs numerous functions, and life as we know it could not exist without it. Ribose in RNA is used in the molecule’s sugar-phosphate “backbone” that connects a string of information-carrying nucleobases.
“All five nucleobases used to construct both DNA and RNA, along with phosphates, have already been found in the Bennu samples brought to Earth by OSIRIS-REx,” said Furukawa. “The new discovery of ribose means that all of the components to form the molecule RNA are present in Bennu.”
The discovery of ribose in asteroid samples is not a complete surprise. Ribose has previously been found in two meteorites recovered on Earth. What is important about the Bennu samples is that researchers did not find deoxyribose. If Bennu is any indication, this means ribose may have been more common than deoxyribose in environments of the early solar system.
Researchers think the presence of ribose and lack of deoxyribose supports the “RNA world” hypothesis, where the first forms of life relied on RNA as the primary molecule to store information and to drive chemical reactions necessary for survival.
A team of Japanese and US scientists have discovered the bio-essential sugars ribose and glucose in samples of asteroid Bennu that were collected by NASA’s OSIRIS-REx mission. This finding builds on the earlier discovery of nucleobases (the genetic components of DNA and RNA), phosphate, and amino acids (the building blocks of proteins) in the Bennu samples, showing that the molecular ingredients of life could have been delivered to early Earth by meteorites.

“Present day life is based on a complex system organized primarily by three types of functional biopolymers: DNA, RNA, and proteins,” explains Furukawa. “However, early life may have been simpler. RNA is the leading candidate for the first functional biopolymer because it can store genetic information and catalyze many biological reactions.”
The Bennu samples also contained one of the most common forms of “food” (or energy) used by life on Earth, the sugar glucose, which is the first evidence that an important energy source for life as we know it was also present in the early solar system.
Mysterious, ancient ‘gum’
A second paper, in the journal Nature Astronomy led by Scott Sandford at NASA’s Ames Research Center in California’s Silicon Valley and Zack Gainsforth of the University of California, Berkeley, reveals a gum-like material in the Bennu samples never seen before in space rocks – something that could have helped set the stage on Earth for the ingredients of life to emerge. The surprising substance was likely formed in the early days of the solar system, as Bennu’s young parent asteroid warmed.
Once soft and flexible, but since hardened, this ancient “space gum” consists of polymer-like materials extremely rich in nitrogen and oxygen. Such complex molecules could have provided some of the chemical precursors that helped trigger life on Earth, and finding them in the pristine samples from Bennu is important for scientists studying how life began and whether it exists beyond our planet.
On this primitive asteroid that formed in the early days of the solar system, we’re looking at events near the beginning of the beginning.

Astrophysicist, NASA's Ames Research Center
Bennu’s ancestral asteroid formed from materials in the solar nebula – the rotating cloud of gas and dust that gave rise to the solar system – and contained a variety of minerals and ices. As the asteroid began to warm, due to natural radiation, a compound called carbamate formed through a process involving ammonia and carbon dioxide. Carbamate is water soluble, but it survived long enough to polymerize, reacting with itself and other molecules to form larger and more complex chains impervious to water. This suggests that it formed before the parent body warmed enough to become a watery environment.
“With this strange substance, we’re looking at, quite possibly, one of the earliest alterations of materials that occurred in this rock,” said Sandford. “On this primitive asteroid that formed in the early days of the solar system, we’re looking at events near the beginning of the beginning.”
Using an infrared microscope, Sandford’s team selected unusual, carbon-rich grains containing abundant nitrogen and oxygen. They then began what Sandford calls “blacksmithing at the molecular level,” using the Molecular Foundry at Lawrence Berkeley National Laboratory (Berkeley Lab) in Berkeley, California. Applying ultra-thin layers of platinum, they reinforced a particle, welded on a tungsten needle to lift the tiny grain, and shaved the fragment down using a focused beam of charged particles.
A microscopic particle of asteroid Bennu, brought to Earth by NASA’s OSIRIS-REx mission, is manipulated under a transmission electron microscope. In order to move the fragment for further analysis, researchers first reinforced it with thin strips of platinum (the “L” shape on the particle’s surface) then welded a tungsten microneedle to it. The asteroid fragment measures 30 micrometers (about one-one thousandth of an inch) across.
NASA/University of California, Berkeley
When the particle was a thousand times thinner than a human hair, they analyzed its composition via electron microscopy at the Molecular Foundry and X-ray spectroscopy at Berkeley Lab’s Advanced Light Source. The ALS’s high spatial resolution and sensitive X-ray beams enabled unprecedented chemical analysis.
“We knew we had something remarkable the instant the images started to appear on the monitor,” said Gainsforth. “It was like nothing we had ever seen, and for months we were consumed by data and theories as we attempted to understand just what it was and how it could have come into existence.”
The team conducted a slew of experiments to examine the material’s characteristics. As the details emerged, the evidence suggested the strange substance had been deposited in layers on grains of ice and minerals present in the asteroid.
It was also flexible – a pliable material, similar to used gum or even a soft plastic. Indeed, during their work with the samples, researchers noticed the strange material was bendy and dimpled when pressure was applied. The stuff was translucent, and exposure to radiation made it brittle, like a lawn chair left too many seasons in the sun.
“Looking at its chemical makeup, we see the same kinds of chemical groups that occur in polyurethane on Earth,” said Sandford, “making this material from Bennu something akin to a ‘space plastic.’”
The ancient asteroid stuff isn’t simply polyurethane, though, which is an orderly polymer. This one has more “random, hodgepodge connections and a composition of elements that differs from particle to particle,” said Sandford. But the comparison underscores the surprising nature of the organic material discovered in NASA’s asteroid samples, and the research team aims to study more of it.
By pursuing clues about what went on long ago, deep inside an asteroid, scientists can better understand the young solar system – revealing the precursors to and ingredients of life it already contained, and how far those raw materials may have been scattered, thanks to asteroids much like Bennu.
Abundant supernova dust
Another paper in the journal Nature Astronomy, led by Ann Nguyen of NASA’s Johnson Space Center in Houston, analyzed presolar grains – dust from stars predating our solar system – found in two different rock types in the Bennu samples to learn more about where its parent body formed and how it was altered by geologic processes. It is believed that presolar dust was generally well-mixed as our solar system formed. The samples had six-times the amount of supernova dust than any other studied astromaterial, suggesting the asteroid’s parent body formed in a region of the protoplanetary disk enriched in the dust of dying stars.
The study also reveals that, while Bennu’s parent asteroid experienced extensive alteration by fluids, there are still pockets of less-altered materials within the samples that offer insights into its origin.

“These fragments retain a higher abundance of organic matter and presolar silicate grains, which are known to be easily destroyed by aqueous alteration in asteroids,” said Nguyen. “Their preservation in the Bennu samples was a surprise and illustrates that some material escaped alteration in the parent body. Our study reveals the diversity of presolar materials that the parent accreted as it was forming.”
NASA’s Goddard Space Flight Center provided overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator. The university leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft and provided flight operations. Goddard and KinetX Aerospace were responsible for navigating the OSIRIS-REx spacecraft. Curation for OSIRIS-REx takes place at NASA’s Johnson Space Center in Houston. International partnerships on this mission include the OSIRIS-REx Laser Altimeter instrument from CSA (Canadian Space Agency) and asteroid sample science collaboration with JAXA’s (Japan Aerospace Exploration Agency’s) Hayabusa2 mission. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

Editor’s Note: This article was updated Nov. 21, 2025 shortly after BioSentinel’s mission marked three years of operation in deep space.
Astronauts live in a pretty extreme environment aboard the International Space Station. Orbiting about 250 miles above the Earth in the weightlessness of microgravity, they rely on commercial cargo missions about every two months to deliver new supplies and experiments. And yet, this place is relatively protected in terms of space radiation. The Earth’s magnetic field shields space station crew from much of the radiation that can damage the DNA in our cells and lead to serious health problems. When future astronauts set off on long journeys deeper into space, they will be venturing into more perilous radiation environments and will need substantial protection. With the help of a biology experiment within a small satellite called BioSentinel, scientists at NASA’s Ames Research Center, in California’s Silicon Valley, are taking an early step toward finding solutions.
To learn the basics of what happens to life in space, researchers often use “model organisms” that we understand relatively well. This helps show the differences between what happens in space and on Earth more clearly. For BioSentinel, NASA is using yeast – the very same yeast that makes bread rise and beer brew. In both our cells and yeast cells, the type of high-energy radiation encountered in deep space can cause breaks in the two entwined strands of DNA that carry genetic information. Often, DNA damage can be repaired by cells in a process that is very similar between yeast and humans.

BioSentinel set out to be the first long-duration biology experiment to take place beyond where the space station orbits near Earth. BioSentinel’s spacecraft is one of 10 CubeSats that launched aboard Artemis I, the first flight of the Artemis program’s Space Launch System, NASA’s powerful new rocket. The cereal box-sized satellite traveled to deep space on the rocket then flew past the Moon in a direction to orbit the Sun. Once the satellite was in position beyond our planet’s protective magnetic field, the BioSentinel team triggered a series of experiments remotely, activating two strains of the yeast Saccharomyces cerevisiae to grow in the presence of space radiation. Samples of yeast were activated at different time points throughout the six- to twelve-month mission.
One strain is the yeast commonly found in nature, while the other was selected because it has trouble repairing its DNA. By comparing how the two strains respond to the deep space radiation environment, researchers will learn more about the health risks posed to humans during long-term exploration and be able to develop informed strategies for reducing potential damage.
During the initial phase of the mission, which began in December 2022 and completed in April 2023, the BioSentinel team successfully operated BioSentinel’s BioSensor hardware – a miniature biotechnology laboratory designed to measure how living yeast cells respond to long-term exposure to space radiation – in deep space. The team completed four experiments lasting two-weeks each but did not observe any yeast cell growth. They determined that deep space radiation was not the cause of the inactive yeast cells, but that their lack of growth was likely due to the yeast expiring after extended storage time of the spacecraft ahead of launch.
Although the yeast did not activate as intended to gather observations on the impact of radiation on living yeast cells, BioSentinel’s onboard radiation detector – that measures the type and dose of radiation hitting the spacecraft – continues to collect data in deep space.

NASA has extended BioSentinel’s mission to continue collecting valuable deep space radiation data in the unique, high-radiation environment beyond low Earth orbit.
The Sun has an 11-year cycle, in which solar activity rises and falls in the form of powerful solar flares and giant eruptions called coronal mass ejections. As the solar cycle progresses from maximum to a declining phase, scientists expect strong solar activity to continue through 2026, with some of the strongest storms seen during this declining phase. These events send powerful bursts of energy, magnetic fields, and plasma into space which causes the aurora and can interfere with satellite signals. Solar radiation events from particles accelerated to high speeds can also pose a threat to astronauts in space.
Built on a history of small-satellite biology
The BioSentinel project builds on Ames’ history of carrying out biology studies in space using CubeSats – small satellites built from individual units each about four inches cubed. BioSentinel is a six-unit spacecraft weighing about 30 pounds. It houses the yeast cells in tiny compartments inside microfluidic cards – custom hardware that allows for the controlled flow of extremely small volumes of liquids that will activate and sustain the yeast. Data about radiation levels and the yeast’s growth and metabolism will be collected and stored aboard the spacecraft and then transmitted to the science team back on Earth.
A reserve set of microfluidic cards containing yeast samples will be activated if the satellite encounters a solar particle event, a radiation storm coming from the Sun that is a particularly severe health risk for future deep space explorers.
BioSentinel’s microfluidics card, designed at NASA’s Ames Research Center in Silicon Valley, California, will be used to study the impact of interplanetary space radiation on yeast. Once in orbit, the growth and metabolic activity of the yeast will be measured using a three-color LED detection system and a dye that provides a readout of yeast cell activity. Here, pink wells contain actively growing yeast cells that have turned the dye from blue to pink color.

Multiple BioSentinels will compare various gravity and radiation environments
In addition to the pioneering BioSentinel mission that will traverse the deep space environment, identical experiments take place under different radiation and gravity conditions. One ran on the space station, in microgravity that is similar to deep space, but with comparatively less radiation. Other experiments took place on the ground, for comparison with Earth’s gravity and radiation levels. These additional versions show scientists how to compare Earth and space station-based science experiments – which can be conducted much more readily – to the fierce radiation that future astronauts will encounter in space.
Taken together, the BioSentinel data will be critical for interpreting the effects of space radiation exposure, reducing the risks associated with long-term human exploration, and confirming existing models of the effects of space radiation on living organisms.

NASA’s X-59 quiet supersonic research aircraft took off for its historic first flight on Oct. 28 at 11:14 a.m. EDT from Lockheed Martin Skunk Works in Palmdale, California. The one-of-a-kind aircraft flew for 67 minutes before landing and taxiing to NASA’s Armstrong Flight Research Center in Edwards, California.
NASA test pilot Nils Larson flew the X-59 up to an altitude of about 12,000 feet and an approximate top speed of 230 mph, precisely as planned. The plane’s landing gear remained down during the entire flight, a common practice for experimental aircraft flying for the first time.
Now that the X-59’s first flight is in the books, the team is focused on preparing for a series of test flights where the aircraft will operate at higher altitudes and supersonic speeds. This test flight phase of NASA’s Quesst mission will ensure the X-59 meets performance and safety expectations.
Through the Quesst mission, NASA aims to usher in a new age of quiet supersonic flight, achieved through the unique design and technology of the X-59 in future supersonic transport aircraft.

NASA’s research into the field of Advanced Air Mobility looks to enable autonomous aircraft with complex capabilities such as carrying cargo or providing medical aid, as seen in this artist’s concept. The Data and Reasoning Fabric project out of Ames Research Center tested delivery of programs and information to these kinds of vehicles.

One of the biggest goals for companies in the field of artificial intelligence is developing “agentic” or autonomous systems. These metaphorical agents can perform tasks without a guiding human hand. This parallels the goals of the emerging urban air mobility industry, which hopes to bring autonomous flying vehicles to cities around the world. One company got a head start on doing both with some help from NASA.
Autonomy Association International Inc. (AAI) is a public benefit corporation based in Mountain View, California, near NASA’s Ames Research Center in Silicon Valley. In 2022, AAI signed a Space Act Agreement with Ames to support the agency’s Data and Reasoning Fabric project, which aimed to support the transportation of people and cargo to areas previously unserved or underserved by aviation, and to provide reliable, accurate, and current data for aeronautic decision-making.
“Inspiration to lean into data fabric to solve certain complexities came from our NASA partnership,” said AAI cofounder and the project’s industry principal investigator Greg Deeds. “Working on this project was a great experience. Working with NASA engineers and leaders gave us experience that we’ll carry forward in all of our products.”
Greg Deeds looks out the window of a helicopter flying over Arizona during a test of Autonomy Association International’s data fabric technology in collaboration with NASA. Through multiple evaluations above Phoenix, the testing proved the capabilities of the company’s Digital Infrastructure Platform.

Similar to how clothing fabric is made of intertwined threads, a data fabric comprises intertwined data sources. While a data fabric built by a tech company may include data from a few different cloud service providers, NASA’s Data and Reasoning Fabric can also use information provided by local governments and other service providers. By viewing airspace as a large data fabric, an autonomous vehicle can take in data and requests from the cities and towns it flies over and prioritize responses between them.
Working with Ken Freeman, principal investigator of the project at Ames, AAI and NASA performed four testing adaptations of the data fabric technology in the air over Arizona. Using hardware and software developed by AAI, the flights tested advanced air mobility passenger flights and the use of a drone for rapid delivery of medical supplies from urban to rural areas and back, while sending new tasks to the aircraft in flight. A helicopter stood in for the drone and air taxi, flying over towns, universities, tribal lands, and the airspace around Phoenix Sky Harbor airport and obtaining data and programs given to it from different places.
“We’re focusing on the digital infrastructure building blocks of smart cities and regions of the future,” said Jennifer Deeds, chief operating officer and cofounder of AAI.
In the years since the original NASA project, the company has cultivated relationships and customers abroad, including companies in agriculture, real estate development, and industrial food production using its system to aggregate and manage data. Released in 2024, the company’s Digital Infrastructure Platform uses the same technology originally designed for the NASA flight test. A new, “agentic” version followed not long after, able to retrieve necessary AI programs with minimal interaction.
As AI unlocks innovation across American industries, NASA is equipping its commercial partners with the keys, using proven technology to generate breakthrough solutions.
