Researchers in the Verification and Validation Lab at NASA’s Ames Research Center in California’s Silicon Valley monitor a simulated drone’s flight path during a test of the FUSE demonstration.NASA/Brandon Torres Navarrete Through an ongoing collaboration, NASA and the Department of War are working to advance the future of modern drones to support long distance cargo transportation that could increase efficiency, reduce human workload, and enhance safety.
Researchers from NASA’s Ames Research Center in California’s Silicon Valley recently participated in a live flight demonstration showcasing how drones can successfully fly without their operators being able to see them, a concept known as beyond visual line of sight (BVLOS).
Cargo drones, a type of Unmanned Aerial Systems (UAS), carried various payloads more than 75 miles across North Dakota, between Grand Forks Air Force Base and Cavalier Space Force Station. This demonstration was conducted as part of the War Department’s UAS Logistics, Traffic, Research, and Autonomy (ULTRA) effort.
NASA’s UAS Service Supplier (USS) technology helped to demonstrate that cargo drones could operate safely even in complex, shared airspace. During the tests, flight data including location, altitude, and other critical data were transmitted live to the NASA system, ensuring full situational awareness throughout the demonstration.
Terrence Lewis and Sheryl Jurcak, members of the FUSE project team at NASA Ames, discuss the monitoring efforts of the FUSE demonstration at the Airspace Operations Lab. NASA/Brandon Torres Navarrete The collaboration between NASA and the Department of War is known as the Federal USS Synthesis Effort (FUSE). The demonstration allowed FUSE researchers to test real-time tracking, situational awareness, and other factors important to safely integrating of drone traffic management into U.S. national airspace. The FUSE work marks an important step towards routine, scalable autonomous cargo drone operations and broader use for future military logistics.
“NASA and the Department of War have a long and storied partnership, collaborating with one another to contribute to continued advancement of shared American ideals,” said Todd Ericson, senior advisor to the NASA administrator. “FUSE builds upon our interagency cooperation to contribute enhanced capabilities for drones flying beyond the visual line of sight. This mission is the next big step toward true autonomous flight and will yield valuable insights that we can leverage as both the commercial drone, cargo and urban air taxi industries continue to expand and innovate. As always, safety is of paramount importance at NASA, and we are working with our partners at the FAA and Department of Transportation to ensure we regulate this appropriately.”
Autonomous and semi-autonomous drones could potentially support a broad range of tasks for commercial, military, and private users. They could transport critical medical supplies to remote locations, monitor wildfires from above, allow customers to receive deliveries directly in their backyards. NASA is researching technology to further develop the infrastructure needed for these operations to take place safely and effectively, without disrupting the existing U.S. airspace.
“This system is crucial for enabling safe, routine BVLOS operations,” said Terrence Lewis, FUSE project manager at NASA Ames. “It ensures all stakeholders can see and respond to drone activity, which provides the operator with greater situational awareness.”
NASA Ames is collaborating on the FUSE project with the War Department’s Office of the Undersecretary of War for Acquisition and Sustainment. The NASA FUSE effort is also collaborating with ULTRA, a multi-entity partnership including the Office of the Secretary of War, the County of Grand Forks, the Northern Plains UAS Test Site, the Grand Sky Development, the Air Force Research Laboratory, and several other commercial partners, aiming to bolster capabilities within the National Airspace System.

Three U.S. military veterans, two from the Air Force and one from the Navy, took the stand Tuesday during the third congressional hearing on Unidentified Anomalous Phenomena (UAPs), the government’s sanitized new term for UFOs.
The most shocking moment came when Congressman Eric Burlison of Missouri unveiled never before seen military footage: a U.S. drone firing a hellfire missile at a mysterious object off the coast of Yemen on October 30, 2024.
The grainy black and white video shows the 100 pound precision weapon streaking toward the target, only to ricochet off harmlessly as the object shot away at impossible speed. Just as baffling, three smaller spheres hovered in formation around the craft, undisturbed by the impact.
Reactions were mixed. Skeptics immediately dismissed the video, claiming it could be nothing more than a misidentified balloon, its apparent speed exaggerated by the drone’s telephoto lens. Others suggested the missile was part of a weapons test rather than a failed strike on something otherworldly.
But the testimony didn’t stop with the video. Two veterans alleged the government has been actively silencing witnesses, threatening those who came forward, and even blacklisting service members who refused to stay quiet. Dylan Borland, a former Air Force geospatial intelligence specialist, testified that multiple agencies conspired to destroy his career blocking jobs, forging documents, and tampering with his security clearance.
For some, this hearing represented a breakthrough in UFO transparency. For others, it was little more than political theater. As one observer put it: it looks like it is just another carefully staged distraction, the UFO spectacle might just be a smokescreen for something deeper.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This artist’s concept shows a brown dwarf — an object larger than a planet but not massive enough to kickstart fusion in its core like a star. Brown dwarfs are hot when they form and may glow like this one, but over time they get closer in temperature to gas giant planets like Jupiter. NOIRLab/NSF/AURA/R. Proctor An unusual cosmic object is helping scientists better understand the chemistry hidden deep in Jupiter and Saturn’s atmospheres — and potentially those of exoplanets.
Why has silicon, one of the most common elements in the universe, gone largely undetected in the atmospheres of Jupiter, Saturn, and gas planets like them orbiting other stars? A new study using observations from NASA’s James Webb Space Telescope sheds light on this question by focusing on a peculiar object that astronomers discovered by chance in 2020 and called “The Accident.”
The results were published on Sept. 4 in the journal Nature.
As shown in this graphic, brown dwarfs can be far more massive than even large gas planets like Jupiter and Saturn. However, they tend to lack the mass that kickstarts nuclear fusion in the cores of stars, causing them to shine. NASA/JPL-Caltech The Accident is a brown dwarf, a ball of gas that’s not quite a planet and not quite a star. Even among its already hard-to-classify peers, The Accident has a perplexing mix of physical features, some of which have been previously seen in only young brown dwarfs and others seen only in ancient ones. Because of those features, it slipped past typical detection methods before being discovered five years ago by a citizen scientist participating in Backyard Worlds: Planet 9. The program lets people around the globe look for new discoveries in data from NASA’s now-retired NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer), which was managed by NASA’s Jet Propulsion Laboratory in Southern California.
The brown dwarf nicknamed “The Accident” can be seen moving in the bottom left corner of this video, which shows data from NASA’s now-retired NEOWISE (Near-Earth Object Wide-Field Infrared Survey Explorer), launched in 2009 with the moniker WISE. NASA/JPL-Caltech/Dan Caselden The Accident is so faint and odd that researchers needed NASA’s most powerful space observatory, Webb, to study its atmosphere. Among several surprises, they found evidence of a molecule they couldn’t initially identify. It turned out to be a simple silicon molecule called silane (SiH4). Researchers have long expected — but been unable — to find silane not only in our solar system’s gas giants, but also in the thousands of atmospheres belonging to brown dwarfs and to the gas giants orbiting other stars. The Accident is the first such object where this molecule has been identified.
Scientists are fairly confident that silicon exists in Jupiter and Saturn’s atmospheres but that it is hidden. Bound to oxygen, silicon forms oxides such as quartz that can seed clouds on hot gas giants, bearing a resemblance to dust storms on Earth. On cooler gas giants like Jupiter and Saturn, these types of clouds would sink far beneath lighter layers of water vapor and ammonia clouds, until any silicon-containing molecules are deep in the atmosphere, invisible even to the spacecraft that have studied those two planets up close.
Some researchers have also posited that lighter molecules of silicon, like silane, should be found higher up in these atmospheric layers, left behind like traces of flour on a baker’s table. That such molecules haven’t appeared anywhere except in a single, peculiar brown dwarf suggests something about the chemistry occurring in these environments.
“Sometimes it’s the extreme objects that help us understand what’s happening in the average ones,” said Faherty, a researcher at the American Museum of Natural History in New York City, and lead author on the new study.
Happy accident
Located about 50 light-years from Earth, The Accident likely formed 10 billion to 12 billion years ago, making it one of the oldest brown dwarfs ever discovered. The universe is about 14 billion years old, and at the time that The Accident developed, the cosmos contained mostly hydrogen and helium, with trace amounts of other elements, including silicon. Over eons, elements like carbon, nitrogen, and oxygen forged in the cores of stars, so planets and stars that formed more recently possess more of those elements.
Webb’s observations of The Accident confirm that silane can form in brown dwarf and planetary atmospheres. The fact that silane seems to be missing in other brown dwarfs and gas giant planets suggests that when oxygen is available, it bonds with silicon at such a high rate and so easily, virtually no silicon is left over to bond with hydrogen and form silane.
So why is silane in The Accident? The study authors surmise it is because far less oxygen was present in the universe when the ancient brown dwarf formed, resulting in less oxygen in its atmosphere to gobble up all the silicon. The available silicon would have bonded with hydrogen instead, resulting in silane.
“We weren’t looking to solve a mystery about Jupiter and Saturn with these observations,” said JPL’s Peter Eisenhardt, project scientist for the WISE (Wide-field Infrared Survey Explorer) mission, which was later repurposed as NEOWISE. “A brown dwarf is a ball of gas like a star, but without an internal fusion reactor, it gets cooler and cooler, with an atmosphere like that of gas giant planets. We wanted to see why this brown dwarf is so odd, but we weren’t expecting silane. The universe continues to surprise us.”
Brown dwarfs are often easier to study than gas giant exoplanets because the light from a faraway planet is typically drowned out by the star it orbits, while brown dwarfs generally fly solo. And the lessons learned from these objects extend to all kinds of planets, including ones outside our solar system that might feature potential signs of habitability.
“To be clear, we’re not finding life on brown dwarfs,” said Faherty. “But at a high level, by studying all of this variety and complexity in planetary atmospheres, we’re setting up the scientists who are one day going to have to do this kind of chemical analysis for rocky, potentially Earth-like planets. It might not specifically involve silicon, but they’re going to get data that is complicated and confusing and doesn’t fit their models, just like we are. They’ll have to parse all those complexities if they want to answer those big questions.”

Hubble Homes in on Galaxy’s Star Formation
This NASA/ESA Hubble Space Telescope image features the asymmetric spiral galaxy Messier 96. ESA/Hubble & NASA, F. Belfiore, D. Calzetti This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the spiral galaxy Messier 96 is the brightest of the galaxies in its group. The gravitational pull of its galactic neighbors may be responsible for Messier 96’s uneven distribution of gas and dust, asymmetric spiral arms, and off-center galactic core.
This asymmetric appearance is on full display in the new Hubble image that incorporates data from observations made in ultraviolet, near infrared, and visible/optical light. Earlier Hubble images of Messier 96 were released in 2015 and 2018. Each successive image added new data, building up a beautiful and scientifically valuable view of the galaxy.
The 2015 image combined two wavelengths of optical light with one near infrared wavelength. The optical light revealed the galaxy’s uneven form of dust and gas spread asymmetrically throughout its weak spiral arms and its off-center core, while the infrared light revealed the heat of stars forming in clouds shaded pink in the image.
The 2018 image added two more optical wavelengths of light along with one wavelength of ultraviolet light that pinpointed areas where high-energy, young stars are forming.
This latest version offers us a new perspective on Messier 96’s star formation. It includes the addition of light that reveals regions of ionized hydrogen (H-alpha) and nitrogen (NII). This data helps astronomers determine the environment within the galaxy and the conditions in which stars are forming. The ionized hydrogen traces ongoing star formation, revealing regions where hot, young stars are ionizing the gas. The ionized nitrogen helps astronomers determine the rate of star formation and the properties of gas between stars, while the combination of the two ionized gasses helps researchers determine if the galaxy is a starburst galaxy or one with an active galactic nucleus.
The bubbles of pink gas in this image surround hot, young, massive stars, illuminating a ring of star formation in the galaxy’s outskirts. These young stars are still embedded within the clouds of gas from which they were born. Astronomers will use the new data in this image to study how stars are form within giant dusty gas clouds, how dust filters starlight, and how stars affect their environments.

Using the Left Navigation Camera (Navcam), the image was acquired on Aug. 17, 2025 (Sol 1597) at the local mean solar time of 13:54:37. NASA/JPL-Caltech Written by Eleanor Moreland, Ph.D. Student Collaborator at Rice University
Perseverance has continued exploring beyond the rim of Jezero crater, spending time last week at Parnasset conducting a mini-campaign on aeolian bedforms. After wrapping up that work, three separate drives brought Perseverance further southeast to an outcrop named Soroya.
Soroya was first picked out from orbital images as a target of interest because, as can be seen in the above image, it appears as a much lighter color compared to the surroundings. In previous landscape images from the surface, Mars 2020 scientists have been able to pick out the light-toned Soryoa outcrop, and they noted it forms a ridge-like structure, protruding above the surface. Soroya was easily identifiable from rover images (below) as Perseverance approached since it indeed rises above the surrounding low-lying terrain.
The Perseverance rover acquired this image looking at Soroya using the onboard Left Navigation Camera (Navcam). This image was acquired on Aug. 15, 2025 (Sol 1595) at the local mean solar time of 16:34:53. NASA/JPL-Caltech From Parnasset to Soroya, the team planned a series of drives so that Perseverance would arrive at Soroya in a great workspace, and the plan was successful. As shown in the first image, we arrived at an area with flat, exposed bedrock – great for proximity science instruments.
The WATSON and SHERLOC ACI cameras plan to acquire many high-resolution images to investigate textures and surface features. For chemistry, SCAM LIBS and ZCAM multispectral activities will give important contextual data for the outcrop while PIXL will acquire a high-resolution chemical map scan of a dust-cleared part of the bedrock. While parked, MEDA will continue monitoring environmental conditions and ZCAM will image the surrounding terrain to inform the next drive location. Take a look at where Perseverance is now – where would you explore next?
