Researchers use a flat aerogel array antenna to communicate with a geostationary satellite above the Earth during tests at NASA’s Glenn Research Center in Cleveland.Credit: NASA/Jordan Cochran NASA engineers are using one of the world’s lightest solid materials to construct an antenna that could be embedded into the skin of an aircraft, creating a more aerodynamic and reliable communication solution for drones and other future air transportation options.
Developed by NASA, this ultra-lightweight aerogel antenna is designed to enable satellite communications where power and space are limited. The aerogel is made up of flexible, high-performance plastics known as polymers. The design features high air content (95%) and offers a combination of light weight and strength. Researchers can adjust its properties to achieve either the flexibility of plastic wrap or the rigidity of plexiglass.
“By removing the liquid portion of a gel, you’re left with this incredibly porous structure,” said Stephanie Vivod, a chemical engineer at NASA’s Glenn Research Center in Cleveland. “If you’ve ever made Jell-O, you’ve performed chemistry that’s similar to the first step of making an aerogel.”
NASA sandwiched a layer of aerogel between a small circuit board and an array of thin, circular copper cells, then topped the design off with a type of film known for its electrical insulation properties. This innovation is known at NASA and in the aviation community as an active phased array aerogel antenna.

They are also less visually intrusive compared to other types of antennas, such as spikes and blades. The finished product looks like a honeycomb but lays flat on an aircraft’s surface.
In the summer of 2024, researchers tested a rigid version of the antenna on a Britten-Norman Defender aircraft during an in-flight demonstration with the U.S. Navy at Naval Air Station Patuxent River in Maryland.

The team successfully connected with a Eutelsat satellite in geostationary orbit, which bounced a signal back down to a satellite dish on a building at Glenn. Other demonstrations of the system at Glenn connected with a constellation of communications satellites operated in low Earth orbit by the data relay company Kepler. NASA researchers will design, build, and test a flexible version of the antenna later this year.
“This is significant because we are able to use the same antenna to connect with two very different satellite systems,” said Glenn researcher Bryan Schoenholz. Low Earth orbit satellites are relatively close – at 1,200 miles from the surface – and move quickly around the planet. Geostationary satellites are much farther – more than 22,000 miles from the surface – but orbit at speeds matching the Earth’s rotation, so they appear to remain in a fixed position above the equator.

When modern aircraft communicate with stations on the ground, those signals are often transmitted through satellite relays, which can come with delays and loss of communication. This NASA-developed technology will make sure these satellite links are not disrupted during flight as the aerogel antenna’s beam is a concentrated flow of radio waves that can be electronically steered with precision to maintain the connection.
As new types of air transportation options are brought to the market and U.S airspace – from the small, piloted aircraft of today to the autonomous air taxis and delivery drones of tomorrow – these kinds of steady connections will become increasingly important. That’s why NASA’s Advanced Air Mobility mission and Transformative Aeronautics Concepts program are supporting research like the aerogel antennas that can boost industry efforts to safely expand the emerging marketplace for these transportation systems.
“If an autonomous air taxi or drone flight loses its communications link, we have a very unsafe situation,” Schoenholz said. “We can’t afford a ‘dropped call’ up there because that connection is critical to the safety of the flight.”
Schoenholz, Vivod, and others work on NASA’s Antenna Deployment and Optimization Technologies activity within the Transformational Tools and Technologies project. The activity aims to develop technologies that reduce the risk of radio frequency interference from air taxis, drones, commercial passenger jets, and other aircraft in increasingly crowded airspace.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Advanced Capabilities for Emergency Response Operations (ACERO) researchers Lynne Martin, left, and Connie Brasil use the Portable Airspace Management System (PAMS) to view a simulated fire zone and set a drone flight plan during a flight test the week of March 17, 2025.NASA/Brandon Torres-Navarrete NASA researchers conducted initial validation of a new airspace management system designed to enable crews to use aircraft fight and monitor wildland fires 24 hours a day, even during low-visibility conditions.
From March 17-28, NASA’s Advanced Capabilities for Emergency Response Operations (ACERO) project stationed researchers at multiple strategic locations across the foothills of the Sierra de Salinas mountains in Monterey County, California. Their mission: to test and validate a new, portable system that can provide reliable airspace management under poor visual conditions, one of the biggest barriers for aerial wildland firefighting support.
The mission was a success.
“At NASA, we have decades of experience leveraging our aviation expertise in ways that improve everyday life for Americans,” said Carol Carroll, deputy associate administrator for NASA’s Aeronautics Research Mission Directorate at agency headquarters in Washington. “We need every advantage possible when it comes to saving lives and property when wildfires affect our communities, and ACERO technology will give responders critical new tools to monitor and fight fires.”
NASA ACERO researchers Samuel Zuniga,left, and Jonathan La Plain prepare for a drone flight test using the PAMS in Salinas on March 19, 2025.NASA/Brandon Torres-Navarrete One of the barriers for continued monitoring, suppression, and logistics support in wildland fire situations is a lack of tools for managing airspace and air traffic that can support operations under all visibility conditions. Current aerial firefighting operations are limited to times with clear visibility when a Tactical Air Group Supervisor or “air boss” in a piloted aircraft can provide direction. Otherwise, pilots may risk collisions.
The ACERO technology will provide that air boss capability for remotely piloted aircraft operations – and users will be able to do it from the ground. The project’s Portable Airspace Management System (PAMS) is a suitcase-sized solution that builds on decades of NASA air traffic and airspace management research. The PAMS units will allow pilots to view the locations and operational intents of other aircraft, even in thick smoke or at night.
During the testing in Salinas, researchers evaluated the PAMS’ core airspace management functions, including strategic coordination and the ability to automatically alert pilots once their aircrafts exit their preapproved paths or the simulated preapproved fire operation zone.
Using the PAMS prototype, researchers were able to safely conduct flight operations of a vertical takeoff and landing aircraft operated by Overwatch Aero, LLC, of Solvang, California, and two small NASA drones.
Flying as if responding to a wildfire scenario, the Overwatch aircraft connected with two PAMS units in different locations. Though the systems were separated by mountains and valleys with weak cellular service, the PAMS units were able to successfully share and display a simulated fire zone, aircraft location, flight plans, and flight intent, thanks to a radio communications relay established by the Overwatch aircraft.
Operating in a rural mountain range validated that PAMS could work successfully in an actual wildland fire environment.
“Testing in real mountainous environments presents numerous challenges, but it offers significantly more value than lab-based testing,” said Dr. Min Xue, ACERO project manager at NASA’s Ames Research Center in California’s Silicon Valley. “The tests were successful, providing valuable insights and highlighting areas for future improvement.”
NASA ACERO researchers fly a drone to test the PAMS during a flight test on March 19, 2025.NASA/Brandon Torres-Navarrete Pilots on the ground used PAMS to coordinate the drones, which performed flights simulating aerial ignition – the practice of setting controlled, intentional fires to manage vegetation, helping to control fires and reduce wildland fire risk.
As a part of the testing, Joby Aviation of Santa Cruz, California, flew its remotely piloted aircraft, similar in size to a Cessna Grand Caravan, over the testing site. The PAMS system successfully exchanged aircraft location and flight intent with Joby’s mission management system. The test marked the first successful interaction between PAMS and an optionally piloted aircraft.
Fire chiefs from the California Department of Forestry and Fire Protection (CAL FIRE) attended the testing and provided feedback on the system’s functionality, features that could improve wildland fire air traffic coordination, and potential for integration into operations.
“We appreciate the work being done by the NASA ACERO program in relation to portable airspace management capabilities,” said Marcus Hernandez, deputy chief for CAL FIRE’s Office of Wildfire Technology. “It’s great to see federal, state, and local agencies, as it is important to address safety and regulatory challenges alongside technological advancements.”

ACERO will use flight test data and feedback from wildland fire agencies to continue building out PAMS capabilities and will showcase more robust information-sharing capabilities in the coming years.
NASA’s goal for ACERO is to validate this technology, so it can be developed for wildland fire crews to use in the field, saving lives and property. The project is managed by NASA’s Airspace Operations and Safety Program and supports the agency’s Advanced Air Mobility mission.

On March 26, 2020, a French astronomer Mark Carlotto used a telescope to capture a video showing the moon at night. Dr. M. Carlotto is a specialist in digital video analysis of space objects. The video shows three objects rising above the Moon’s limb, flying across the lunar surface and disappearing in the Moon’s shadow.
The fact that some of these objects are so clearly visible and close enough to the moon to be able to cast noticeable shadows immediately suggests that they are quite large. Using the large Endymion crater as a benchmark, the sizes of the objects were determined.
The size of the object flying over Endymion is about 5 miles long and about 1 to 3 miles wide. The other two objects appear to be comparable in size.
By measuring the displacement of the object it appears that the object is traveling at about 31 mps. It is traveling more than 30 times faster than if it were in lunar orbit.
A paper was recently published that attempts to prove that the original video is a fake. Arxiv.org analyzed the video (not included in the analysis) but extracted and provided three images of the recorded objects for examination, as seen above, and they then conducted calculations to verify its authenticity.
Despite government and space agency denials of UFO existence, photographic evidence and subsequent analysis suggest the presence of large extraterrestrial craft near the Moon and elsewhere in space.View the full article

Artist’s concept of drones flying in an urban environment near large city skyscrapers.NASA / Maria Werries Remotely piloted aircraft could transform the way we transport people and goods and provide our communities with better access to vital services, like medical supply deliveries and efficient transportation.
NASA’s Pathfinding for Airspace with Autonomous Vehicles (PAAV) subproject is working with partners to safely integrate remote air cargo and air taxi aircraft into our national airspace alongside traditional crewed aircraft.
These new types of vehicles could make air cargo deliveries and air travel more affordable and accessible to communities across the country.
The Need
The United States large air cargo fleet is expected to grow significantly through 2044 to meet cargo demand, according to the Federal Aviation Administration (FAA).
However, pilot shortages exacerbated by early retirements and crew reductions implemented during the coronavirus outbreak continue to present a challenge to the air cargo industry.
In the future, one pilot could potentially manage multiple aircraft remotely. This could help meet the rising demand for air cargo operations, mitigate pilot shortages and costs, and increase the number of daily air cargo deliveries.
Additionally, remotely piloted air taxis could reduce travel time for passengers and alleviate traffic congestion because they could avoid crowded roads and highways.
Identifying the Technical Challenges
Commercial companies are investing in autonomous technologies to enable remote air cargo deliveries and air taxi operations.
NASA is working with the industry along the way to identify the unique technical challenges that must be overcome to safely put these new types of aircraft into routine operation.
The agency has identified several challenges that need to be addressed for safe and scalable remote operations. Among these challenges are airspace integration, avoiding airborne and ground-based hazards, and resilient communication technologies.
The main difference between conventional crewed aircraft and remotely piloted aircraft is the location of the pilot. Remote pilots operate aircraft from a control station on the ground instead of the cockpit.
This means remote pilots will need new automation and decision support systems for operating the aircraft since they can’t rely on their eyes and view from the cockpit. Since remote pilots are on the ground, they need a reliable communications link that allows remote pilots to interact with the aircraft and maintain command and control.
If the command-and-control capabilities are lost, an autonomous system would need to take over to make sure the uncrewed aircraft can fly and land safely, according to NASA researchers. Adequate software and procedures must be in place to safely manage off-nominal losses of the command-and-control capabilities.
Air Traffic Control may help keep the uncrewed aircraft’s path clear from some traffic during takeoff and landing, while onboard automation technologies would need to avoid all other traffic, fly the aircraft along a known path, and check to ensure the runway is clear to land.
A significant related challenge is that pilots are typically responsible for looking out the window for nearby aircraft and remaining well clear of them. Since the remote pilot is not in the aircraft, they will need an electronic detect and avoid system.
Detect and avoid systems rely on information, sensors, and algorithms to help the remotely piloted aircraft remain clear of other aircraft. Some detect and avoid configurations are expected to use ground surveillance systems for detecting nearby air traffic at lower altitudes.
These systems could improve overall situational awareness of traffic near the airport by providing a more comprehensive picture of live traffic.
Additionally, automation and decision support tools could help remote pilots with other responsibilities that typically require pilot decisions from the cockpit, like integrating with traffic at non-towered airports.
Implementing Solutions
To address these challenges and others, NASA researchers are working with industry partners to research and test technologies, concepts, and airspace procedures that will enable remotely piloted operations.
For example, industry is developing automated taxi, takeoff, and landing capabilities to help integrate remotely piloted aircraft operating at busy airports.
These technologies could enable aircraft to navigate and integrate with other airport traffic autonomously, following standard routes and air traffic control commands for safe sequencing and spacing between other aircraft.
Automated hazard detection would enable the aircraft to identify potential conflicts or hazards and take corrective actions without input from a remote pilot. This would ensure the aircraft safely navigates the airport environment even if the remote pilot is supervising multiple aircraft or their response is delayed.
NASA researchers are beginning to test emerging technologies for remotely piloted aircraft operations with commercial partners. The goal is to help mature technical standards and assist in the development of certification requirements anrtd procedures required to integrate remotely piloted operations into the airspace.
NASA aims to bridge technical and regulatory gaps through these industry partnerships involving research, testing, and development. Ultimately, NASA hopes to enable pilots to remotely fly multiple large aircraft to airports across the country at once, more efficiently transporting people and goods.
This could enable carriers to meet rising air travel and transport demands in a safe, affordable, scalable way and expand access to new communities.
PAAV is a subproject under NASA’s Air Traffic Management Exploration project within the agency’s Aeronautics Research Mission Directorate.

EBANI stands for "Unidentified Anomalous Biological Entity," referring to a mysterious class of airborne phenomena that may be biological rather than mechanical in nature. These entities are often described as elongated, flexible, and tubular, moving through the sky in a serpentine or twisting manner.
They exhibit advanced flight capabilities, including high-speed travel, precise control, and even self-illumination. Some have been observed rendering themselves invisible, raising questions about their energy sources and possible technological origins.
Recent observations have revealed formations of translucent spheres in red, white, and blue, challenging conventional classifications of both biology and aerodynamics.
Some of these entities have a massive structure composed of thousands of clustered spheres. These entities appear to function as an aircraft carrier, releasing these smaller spheres into Earth's atmosphere for an unknown purpose.
While some researchers propose that EBANIs are natural organisms evolving in Earth's upper atmosphere under unfamiliar physical laws, others speculate they may be advanced artificial (eventually biological) constructs, potentially extraterrestrial probes or surveillance devices, given the presence of large structures expelling numerous smaller spheres.
Are they living UFOs, advanced biological organisms that function autonomously within the spheres, without the need for pilots?
