Preparations for Next Moonwalk Simulations Underway (and Underwater)
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.

Flight Engineer Joe Acaba works in the U.S. Destiny laboratory module on the International Space Station, setting up hardware for the Zero Boil-Off Tank (ZBOT) experiment. Joe Acaba Space missions rely on cryogenic fluids — extremely cold liquids like liquid hydrogen and oxygen — for both propulsion and life support systems. These fuels must be kept at ultra-low cryogenic temperatures to remain in liquid form; however, solar heating and other sources of heat increase the rate of evaporation of the liquid and cause the pressure in the storage tank to increase. Current storage methods require venting the cryogenic propellant to space to control the pressure in fuel tanks.
NASA’s Zero Boil-Off Tank Noncondensables (ZBOT-NC) experiment is the continuation of Zero Boil-Off studies gathering crucial data to optimize fuel storage systems for space missions. The experiment will launch aboard Northrop Grumman’s 23rd resupply mission to the International Space Station.
When Cold Fuel Gets Too Warm
Even with multilayer insulation, heat unavoidably seeps into cryogenic fuel tanks from surrounding structures and the space environment, causing an increase in the liquid temperature and an associated increase in the evaporation rate. In turn, the pressure inside the tank increases. This process is called “boil-off” and the increase in tank pressure is referred to as “self-pressurization.”
Venting excess gas to the environment or space when this process occurs is highly undesirable and becomes mission-critical on extended journeys. If crew members used current fuel storage methods for a years-long Mars expedition, all propellant might be lost to boil-off before the trip ends.
NASA’s ZBOT experiments are investigating active pressure control methods to eliminate wasteful fuel venting. Specifically, active control through the use of jet mixing and other techniques are being evaluated and tested in the ZBOT series of experiments.
The Pressure Control Problem
ZBOT-NC further studies how noncondensable gases (NCGs) affect fuel tank behavior when present in spacecraft systems. NCGs don’t turn into liquid under the tank’s operating conditions and can affect tank pressure.
The investigation, which is led out of Glenn Research Center, will operate inside the Microgravity Science Glovebox aboard the space station to gather data on how NCGs affect volatile liquid behavior in microgravity. It’s part of an effort to advance cryogenic fluid management technologies and help NASA better understand low-gravity fluid behavior.
Researchers will measure pressure and temperature as they study how these gases change evaporation and condensation rates. Previous studies indicate the gases create barriers that could reduce a tank’s ability to maintain proper pressure control — a potentially serious issue for extended space missions.
How this benefits space exploration
The research directly supports Mars missions and other long-duration space travel by helping engineers design more efficient fuel storage systems and future space depots. The findings may also benefit scientific instruments on space telescopes and probes that rely on cryogenic fluids to maintain the extremely low temperatures needed for operation.
How this benefits humanity
The investigation could improve tank design models for medical, industrial, and energy production applications that depend on long-term cryogenic storage on Earth.

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.

Credit: ResilienX A future with advanced air mobility aircraft populating the skies will require the U.S. to implement enhanced preflight planning that can mitigate potential risks well before takeoff – and NASA is working to develop the tools to make that happen.
Preflight planning is critical to ensuring safety in the complex, high-risk environments of the future airspace. Timely, predictive, and up-to-date risk assessment within a single platform makes it much easier for drone or air taxi operators to check flight plans for high-risk concerns.
NASA is working on tools to deliver those services, and in June, the agency and aviation safety company ResilienX Inc. demonstrated how these tools can be integrated into commercial systems.
During a series of tests conducted at ResilienX’s facility in Syracuse, New York, researchers used NASA services that allowed flight operators to submit flight plans prior to departure, obtain risk assessment results, and then decide whether to proceed with flights or change their flight plans and re-assess risks. Allowing operators to perform these tasks quickly reduces the safety risk to flight passengers as well as humans on the ground.
The three NASA-developed services are intended to assess unique risks associated with highly automated aircraft flying at low altitudes over cities.
The partnership was managed under a Phase III NASA Small Business Innovation Research (SBIR) contract, which is an extension of prior work to assess weather-related risks. This collaboration is already leading to direct technology transfer of safety systems into ResilienX’s platform. The partnership is also intended to provide indirect benefits for ResilienX partners and customers, such as the U.S. Air Force and regional operators, helping to advance the overall safety of future airspace operations.
This work is led by NASA’s System-Wide Safety project under the Airspace Operations and Safety program in support of the agency’s Advanced Air Mobility mission. The mission seeks to deliver data, findings, and recommendations to guide the industry’s development of future air taxis and drones.

NASA’s Bennu Samples Reveal Complex Origins, Dramatic Transformation
Asteroid Bennu, sampled by NASA’s OSIRIS-REx mission in 2023, is a mixture of dust that formed in our solar system, organic matter from interstellar space, and pre-solar system stardust. Its unique and varied contents were dramatically transformed over time by interactions with water and exposure to the harsh space environment.
These insights come from a trio of newly published papers based on the analysis of Bennu samples by scientists at NASA and other institutions.
Bennu is made of fragments from a larger parent asteroid destroyed by a collision in the asteroid belt, between the orbits of Mars and Jupiter. One of the papers, co-led by Jessica Barnes at the University of Arizona, Tucson, and Ann Nguyen of NASA’s Johnson Space Center in Houston and published in the journal Nature Astronomy, suggests that Bennu’s ancestor was made up of material that had diverse origins—near the Sun, far from the Sun, and even beyond our solar system.
The analyses show that some of the materials in the parent asteroid, despite very low odds, escaped various chemical processes driven by heat and water and even survived the extremely energetic collision that broke it apart and formed Bennu.
“We traced the origins of these initial materials accumulated by Bennu’s ancestor,” said Nguyen. “We found stardust grains with compositions that predate the solar system, organic matter that likely formed in interstellar space, and high temperature minerals that formed closer to the Sun. All of these constituents were transported great distances to the region that Bennu’s parent asteroid formed.”
The chemical and atomic similarities of samples from Bennu, the asteroid Ryugu (sampled by JAXA’s (the Japan Aerospace Exploration Agency) Hayabusa2 mission) and the most chemically primitive meteorites collected on Earth suggest their parent asteroids may have formed in a similar, distant region of the early solar system. Yet the differences from Ryugu and meteorites that were seen in the Bennu samples may indicate that this region changed over time or did not mix as well as some scientists have thought.
We found stardust grains with compositions that predate the solar system, organic matter that likely formed in interstellar space, and high temperature minerals that formed closer to the Sun.

Though some original constituents survived, most of Bennu’s materials were transformed by reactions with water, as reported in the paper co-led by Tom Zega of the University of Arizona and Tim McCoy of the Smithsonian’s National Museum of Natural History in Washington and published in Nature Geoscience. In fact, minerals in the parent asteroid likely formed, dissolved, and reformed over time.
“Bennu’s parent asteroid accumulated ice and dust. Eventually that ice melted, and the resulting liquid reacted with the dust to form what we see today, a sample that is 80% minerals that contain water,” said Zega. “We think the parent asteroid accumulated a lot of icy material from the outer solar system, and then all it needed was a little bit of heat to melt the ice and cause liquids to react with solids.”
Bennu’s transformation did not end there. The third paper, co-led by Lindsay Keller at NASA Johnson and Michelle Thompson of Purdue University, also published in Nature Geoscience, found microscopic craters and tiny splashes of once-molten rock – known as impact melts – on the sample surfaces, signs that the asteroid was bombarded by micrometeorites. These impacts, together with the effects of solar wind, are known as space weathering and occurred because Bennu has no atmosphere to protect it.
“The surface weathering at Bennu is happening a lot faster than conventional wisdom would have it, and the impact melt mechanism appears to dominate, contrary to what we originally thought,” said Keller. “Space weathering is an important process that affects all asteroids, and with returned samples, we can tease out the properties controlling it and use that data and extrapolate it to explain the surface and evolution of asteroid bodies that we haven’t visited.”
Ann Nguyen, co-lead author of a new paper that gives insights into the diverse origin of asteroid Bennu’s “parent” asteroid works alongside the NanoSIMS 50L (nanoscale secondary ion mass spectrometry) ion microprobe in the Astromaterials Research and Exploration Science Division at NASA’s Johnson Space Center in Houston. Credit: NASA/James Blair As the leftover materials from planetary formation 4.5 billion years ago, asteroids provide a record of the solar system’s history. But as Zega noted, we’re seeing that some of these remnants differ from what has been found in meteorites on Earth, because certain types of asteroids burn up in the atmosphere and never make it to the ground. That, the researchers point out, is why collecting actual samples is so important.
“The samples are really crucial for this work,” Barnes said. “We could only get the answers we got because of the samples. It’s super exciting that we’re finally able to see these things about an asteroid that we’ve been dreaming of going to for so long.”
The next samples NASA expects to help unravel our solar system’s story will be Moon rocks returned by the Artemis III astronauts.
