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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A NASA F/A-18 research aircraft flies above California near NASA’s Armstrong Flight Research Center in Edwards, California, testing a commercial precision landing technology for future space missions. The Psionic Space Navigation Doppler Lidar (PSNDL) system is installed in a pod located under the right wing of the aircraft.NASA Nestled in a pod under an F/A-18 Hornet aircraft wing, flying above California, and traveling up to the speed of sound, NASA put a commercial sensor technology to the test. The flight tests demonstrated the sensor accuracy and navigation precision in challenging conditions, helping prepare the technology to land robots and astronauts on the Moon and Mars.
The Psionic Space Navigation Doppler Lidar (PSNDL) system is rooted in NASA technology that Psionic, Inc. of Hampton, Virginia, licensed and further developed. They miniaturized the NASA technology, added further functionality, and incorporated component redundancies that make it more rugged for spaceflight. The PSNDL navigation system also includes cameras and an inertial measurement unit to make it a complete navigation system capable of accurately determining a vehicle’s position and velocity for precision landing and other spaceflight applications.
NASA engineers and technicians install the Psionic Space Navigation Doppler Lidar (PSNDL) system into a testing pod on a NASA F/A-18 research aircraft ahead of February 2025 flight tests at NASA’s Armstrong Flight Research Center in Edwards, California.NASA The aircraft departed from NASA’s Armstrong Flight Research Center in Edwards, California, and conducted a variety of flight paths over several days in February 2025. It flew a large figure-8 loop and conducted several highly dynamic maneuvers over Death Valley, California, to collect navigation data at various altitudes, velocities, and orientations relevant for lunar and Mars entry and descent. Refurbished for these tests, the NASA F/A-18 pod can support critical data collection for other technologies and users at a low cost.
Doppler Lidar sensors provide a highly accurate measurement of speed by measuring the frequency shift between laser light emitted from the sensor reflected from the ground. Lidar are extremely useful in sunlight-challenged areas that may have long shadows and stark contrasts, such as the lunar South Pole. Pairing PSNDL with cameras adds the ability to visually compare pictures with surface reconnaissance maps of rocky terrain and navigate to landing at interesting locations on Mars. All the data is fed into a computer to make quick, real-time decisions to enable precise touchdowns at safe locations.

The company has also tested PSNDL prototypes on suborbital vehicles via the Flight Opportunities program. In 2024, onboard a commercial lunar lander, NASA successfully demonstrated the predecessor NDL system developed by the agency’s Langley Research Center in Hampton, Virginia.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA astronaut and Expedition 72 Commander Suni Williams displays a set of BioNutrients production packs during an experiment aboard the International Space Station. The experiment uses engineered yeast to produce nutrients and vitamins to support future astronaut health.NASA NASA’s BioNutrients series of experiments is testing ways to use microorganisms to make nutrients that will be needed for human health during future long-duration deep space exploration missions. Some vital nutrients lack the shelf-life needed to span multi-year human missions, such as a mission to Mars, and may need to be produced in space to support astronaut health. To meet this need, the BioNutrients project uses a biomanufacturing approach similar to making familiar fermented foods, such as yogurt. But these foods also will include specific types and amounts of nutrients that crew will be able to consume in the future.
The first experiment in the series, BioNutrients-1, set out to assess the five-year stability and performance of a hand-held system – called a production pack – that uses an engineered microorganism, yeast, to manufacture fresh vitamins on-demand and in space. The BioNutrients-1 experiments began after multiple sets of production packs launched to the station in 2019. This collection included spare production packs as backups to be used in case an experiment needs to be re-run during the five-year study. The planned experiments concluded in January 2024 spare production packs still remaining aboard the orbiting lab and in the BioNutrients lab at NASA’s Ames Research Center in California’s Silicon Valley, where the ground team runs experiments in parallel to the crew operations.
Leaders at NASA’s International Space Station and Game Changing Development programs worked to coordinate the crew time needed to perform an additional BioNutrients-2 experiment using the spare packs. This extended the study’s timeline to almost six years in orbit, allowing valuable crew observations and data from the additional experiment run to be applied to a follow-on experiment, BioNutrients-3, which completed its analog astronaut experiment in April 2024, and is planned to launch to the station this year. Astronauts on the space station will freeze the sample and eventually it will be returned to Earth for analysis to see how much yeast grew and how much nutrient the experiment produced. This will help us understand how the shelf stability of the packets.
