Preparations for Next Moonwalk Simulations Underway (and Underwater)
A Massachusetts Institute of Technology Lincoln Laboratory pilot controls a drone during NASA’s In-Time Aviation Safety Management System test series in collaboration with a George Washington University team July 17-18, 2024, at the U.S. Army’s Fort Devens in Devens, Massachusetts. MIT Lincoln Laboratory/Jay Couturier From agriculture and law enforcement to entertainment and disaster response, industries are increasingly turning to drones for help, but the growing volume of these aircraft will require trusted safety management systems to maintain safe operations.
NASA is testing a new software system to create an improved warning system – one that can predict hazards to drones before they occur. The In-Time Aviation Safety Management System (IASMS) will monitor, assess, and mitigate airborne risks in real time. But making sure that it can do all that requires extensive experimentation to see how its elements work together, including simulations and drone flight tests.
“If everything is going as planned with your flight, you won’t notice your in-time aviation safety management system working,” said Michael Vincent, NASA acting deputy project manager with the System-Wide Safety project at NASA’s Langley Research Center in Hampton, Virginia. “It’s before you encounter an unusual situation, like loss of navigation or communications, that the IASMS provides an alert to the drone operator.”
The team completed a simulation in the Human-Autonomy Teaming Laboratory at NASA’s Ames Research Center in California’s Silicon Valley on March 5 aimed at finding out how critical elements of the IASMS could be used in operational hurricane relief and recovery.
During this simulation, 12 drone pilots completed three 30-minute sessions where they managed up to six drones flying beyond visual line of sight to perform supply drops to residents stranded after a severe hurricane. Additional drones flew scripted search and rescue operations and levee inspections in the background. Researchers collected data on pilot performance, mission success, workload, and perceptions of the experiences, as well as the system’s usability.
This simulation is part of a longer-term strategy by NASA to advance this technology. The lessons learned from this study will help prepare for the project’s hurricane relief and recovery flight tests, planned for 2027.
As an example of this work, in the summer of 2024 NASA tested its IASMS during a series of drone flights in collaboration with the Ohio Department of Transportation in Columbus, Ohio, and in a separate effort, with three university-led teams.
For the Ohio Department of Transportation tests, a drone flew with the NASA-developed IASMS software aboard, which communicated back to computers at NASA Langley. Those transmissions gave NASA researchers input on the system’s performance.
Students from the Ohio State University participate in drone flights during NASA’s In-Time Aviation Safety Management System test series in collaboration with the Ohio Department of Transportation from March to July 2024 at the Columbus Aero Club in Ohio. NASA/Russell Gilabert NASA also conducted studies with The George Washington University (GWU), the University of Notre Dame, and Virginia Commonwealth University (VCU). These occurred at the U.S. Army’s Fort Devens in Devens, Massachusetts with GWU; near South Bend, Indiana with Notre Dame; and in Richmond, Virginia with VCU. Each test included a variety of types of drones, flight scenarios, and operators.
Students from Virginia Commonwealth University walk toward a drone after a flight as part of NASA’s In-Time Aviation Safety Management System (IASMS) test series July 16, 2024, in Richmond, Virginia. NASA/Dave Bowman Each drone testing series involved a different mission for the drone to perform and different hazards for the system to avoid. Scenarios included, for example, how the drone would fly during a wildfire or how it would deliver a package in a city. A different version of the NASA IASMS was used to fit the scenario depending on the mission, or depending on the flight area.
Students from the University of Notre Dame prepare a small drone for takeoff as part of NASA’s In-Time Aviation Safety Management System (IASMS) university test series, which occurred on August 21, 2024 in Notre Dame, Indiana.University of Notre Dame/Wes Evard When used in conjunction with other systems such as NASA’s Unmanned Aircraft System Traffic Management, IASMS may allow for routine drone flights in the U.S. to become a reality. The IASMS adds an additional layer of safety for drones, assuring the reliability and trust if the drone is flying over a town on a routine basis that it remains on course while avoiding hazards along the way.
“There are multiple entities who contribute to safety assurance when flying a drone,” Vincent said. “There is the person who’s flying the drone, the company who designs and manufactures the drone, the company operating the drone, and the Federal Aviation Administration, who has oversight over the entire National Airspace System. Being able to monitor, assess and mitigate risks in real time would make the risks in these situations much more secure.”
All of 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, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.

El equipo detrás del X-59 de la NASA completó en marzo otra prueba crítica en tierra, garantizando que el silencioso avión supersónico será capaz de mantener una velocidad específica durante su funcionamiento. Esta prueba, conocida como mantenimiento automático de velocidad del motor, es el más reciente marcador de progreso a medida que el X-59 se acerca a su primer vuelo este año.
“El mantenimiento automático de la velocidad del motor es básicamente la versión de control de crucero de la aeronave,” explicó Paul Dees, jefe adjunto de propulsión de la NASA del X-59 en el Centro de Investigación de Vuelo Armstrong de la agencia en Edwards, California. “El piloto activa el control de velocidad a su velocidad actual y luego puede aumentarla o ajustarla gradualmente según sea necesario.”
El equipo del X-59 ya había realizado una prueba similar en el motor, pero sólo como un sistema aislado. La prueba de marzo verificó que la retención de velocidad funciona correctamente tras su integración en la aviónica de la aeronave.
“Necesitábamos verificar que el mantenimiento automático de velocidad funcionara no sólo dentro del propio motor, sino como parte de todo el sistema del avión,” explicó Dees. “Esta prueba confirmó que todos los componentes – software, enlaces mecánicos y leyes de control – funcionan juntos según lo previsto.”
El éxito de la prueba confirmó la habilidad de la aeronave para controlar la velocidad con precisión, lo cual será muy invaluable durante el vuelo. Esta capacidad aumentará la seguridad de los pilotos, permitiéndoles enfocarse en otros aspectos críticos de la operación de vuelo.
“El piloto va a estar muy ocupado durante el primer vuelo, asegurándose de que la aeronave sea estable y controlable,” dijo Dees. “Al tener la función del mantenimiento automático de velocidad, de reduce parte de esa carga de trabajo, lo que hace que el primer vuelo sea mucho más seguro.”
Inicialmente el equipo tenía planeado comprobar el mantenimiento automático de velocidad como parte de una próxima serie de pruebas en tierra donde alimentarían la aeronave con un sólido conjunto de datos para verificar su funcionalidad tanto en condiciones normales como de fallo, conocidas como pruebas de pájaro de aluminio (una estructura que se utiliza para probar los sistemas de una aeronave en un laboratorio, simulando un vuelo real). Sin embargo, el equipo se dio cuenta que había una oportunidad de probarlo antes.
“Fue un objetivo de oportunidad,” dijo Dees. “Nos dimos cuenta de que estábamos listos para probar el mantenimiento automático de velocidad del motor por separado mientras otros sistemas continuaban con la finalización de su software. Si podemos aprender algo antes, siempre es mejor.”
Con cada prueba exitosa, el equipo integrado de la NASA y Lockheed Martin acerca el X-59 al primer vuelo, y hacer historia en la aviación a través de su tecnología supersónica silenciosa.

Visiting Mars on the Way to the Outer Solar System
Written by Roger Wiens, Principal Investigator, SuperCam instrument / Co-Investigator, SHERLOC instrument at Purdue University
A portion of the “Sally’s Cove” outcrop where the Perseverance rover has been exploring. The radiating lines in the rock on the left of the image may indicate that it is a shatter cone, showing the effects of the shock wave from a nearby large impact. The image was taken by Mastcam-Z’s left camera on March 21, 2025 (Sol 1452, or Martian day 1,452 of the Mars 2020 mission) at the local mean solar time of 12:13:44. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was voted by the public as “Image of the week.” NASA/JPL-Caltech/ASU Recently Mars has had a few Earthly visitors. On March 1, NASA’s Europa Clipper flew within 550 miles (884 kilometers) of the Red Planet’s surface on its way out to Jupiter. On March 12, the European Space Agency’s Hera spacecraft flew within about 3,100 miles (5,000 kilometers) of Mars, and only 300 kilometers from its moon, Deimos. Hera is on its way to study the binary asteroid Didymos and its moon Dimorphos. Next year, in May 2026, NASA’s Psyche mission is scheduled to buzz the Red Planet on its way to the metal-rich asteroid 16 Psyche, coming within a few thousand kilometers.
Why all these visits to Mars? You might at first think that they’re using Mars as an object of opportunity for their cameras, and you would be partially right. But Mars has more to give these missions than that. The main reason for these flybys is the extra speed that Mars’ velocity around the Sun can give them. The idea that visiting a planet can speed up a spacecraft is not all that obvious, because the same gravity that attracts the spacecraft on its way towards the planet will exert a backwards force as the spacecraft leaves the planet.
The key is in the direction that it approaches and leaves the planet. If the spacecraft leaves Mars heading in the direction that Mars is traveling around the Sun, it will gain speed in that direction, slingshotting it farther into the outer solar system. A spacecraft can typically gain several percent of its speed by performing such a slingshot flyby. The closer it gets to the planet, the bigger the effect. However, no mission wants to be slowed by the upper atmosphere, so several hundred kilometers is the closest that a mission should go. And the proximity to the planet is also affected by the exact direction the spacecraft needs to go when it leaves Mars.
Clipper’s Mars flyby was a slight exception, slowing down the craft — by about 1.2 miles per second (2 kilometers per second) — to steer it toward Earth for a second gravity assist in December 2026. That will push the spacecraft the rest of the way to Jupiter, for its 2030 arrival.
While observing Mars is not the main reason for their visits, many of the visiting spacecraft take the opportunity to use their cameras either to perform calibrations or to study the Red Planet and its moons.
During Clipper’s flyby over sols 1431-1432, Mastcam-Z was directed to watch the skies for signs of the interplanetary visitor. Clipper’s relatively large solar panels could have reflected enough sunlight for it to be seen in the Mars night sky, much as we can see satellites overhead from Earth. Unfortunately, the spacecraft entered the shadow of Mars just before it came into potential view above the horizon from Perseverance’s vantage point, so the sighting did not happen. But it was worth a try.
Meanwhile, back on the ground, Perseverance is performing something of a cliff-hanger. “Sally’s Cove” is a relatively steep rock outcrop in the outer portion of Jezero crater’s rim just north of “Broom Hill.” Perseverance made an approach during March 19-23, and has been exploring some dark-colored rocks along this outcrop, leaving the spherules behind for the moment. Who knows what Perseverance will find next?

NASA’s Electrodynamic Dust Shield (EDS) successfully demonstrated its ability to remove regolith, or lunar dust and dirt, from its various surfaces on the Moon during Firefly Aerospace’s Blue Ghost Mission 1, which concluded on March 16. Lunar dust is extremely abrasive and electrostatic, which means it clings to anything that carries a charge. It can damage everything from spacesuits and hardware to human lungs, making lunar dust one of the most challenging features of living and working on the lunar surface. The EDS technology uses electrodynamic forces to lift and remove the lunar dust from its surfaces. The first image showcases the glass and thermal radiator surfaces, coated in a layer of regolith. As you slide to the left, the photo reveals the results after EDS activation. Dust was removed from both surfaces, proving the technology’s effectiveness in mitigating dust accumulation.
This milestone marks a significant step toward sustaining long-term lunar and interplanetary operations by reducing dust-related hazards to a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. The EDS technology is paving the way for future dust mitigation solutions, supporting NASA’s Artemis campaign and beyond. NASA’s Electrodynamic Dust Shield was developed at Kennedy Space Center in Florida with funding from NASA’s Game Changing Development Program, managed by the agency’s Space Technology Mission Directorate.
