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.

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)
The Starling swarm’s extended mission tested advanced autonomous maneuvering capabilities.NASA/Daniel Rutter As missions to low Earth orbit become more frequent, space traffic coordination remains a key element to efficiently operating in space. Different satellite operators using autonomous systems need to operate together and manage increasing workloads. NASA’s Starling spacecraft swarm recently tested a coordination with SpaceX’s Starlink constellation, demonstrating a potential solution to enhance space traffic coordination.
Led by the Small Spacecraft Technology program at NASA’s Ames Research Center in California’s Silicon Valley, Starling originally set out to demonstrate autonomous planning and execution of orbital maneuvers with the mission’s four small spacecraft. After achieving its primary objectives, the Starling mission expanded to become Starling 1.5, an experiment to demonstrate maneuvers between the Starling swarm and SpaceX’s Starlink satellites, which also maneuver autonomously.
Coordination in Low Earth Orbit
Current space traffic coordination systems screen trajectories of spacecraft and objects in space and alert operators on the ground of potential conjunctions, which occur when two objects exceed an operator’s tolerance for a close approach along their orbital paths. Spacecraft operators can request notification at a range of probabilities, often anywhere from a 1 in 10,000 likelihood of a collision to 1 in 1,000,000 or lower.
Conjunction mitigation between satellite operators requires manual coordination through calls or emails on the ground. An operator may receive a notification for a number of reasons including recently maneuvering their satellite, nearby space debris, or if another satellite adjusts its orbit.
Once an operator is aware of a potential conjunction, they must work together with other operators to reduce the probability of a collision. This can result in time-consuming calls or emails between ground operations teams with different approaches to safe operations. It also means maneuvers may require several days to plan and implement. This timeline can be challenging for missions that require quick adjustments to capture important data.
“Occasionally, we’ll do a maneuver that we find out wasn’t necessary if we could have waited before making a decision. Sometimes you can’t wait three days to reposition and observe. Being able to react within a few hours can make new satellite observations possible,” said Nathan Benz, project manager of Starling 1.5 at NASA Ames.
Improving Coordination for Autonomous Maneuvering
The first step in improving coordination was to develop a reliable way to signal maneuver responsibility between operators. “Usually, SpaceX takes the responsibility to move out of the way when another operator shares their predicted trajectory information,” said Benz.
SpaceX and NASA collaborated to design a conjunction screening service, which SpaceX then implemented. Satellite operators can submit trajectories and receive conjunction data quickly, then accept responsibility to maneuver away from a potential conjunction.
“For this experiment, NASA’s Starling accepted responsibility to move using the screening service, successfully tested our system’s performance, then autonomously planned and executed the maneuver for the NASA Starling satellite, resolving a close approach with a Starlink satellite,” said Benz.
Through NASA’s Starling 1.5 experiment, the agency helped validate SpaceX’s Starlink screening service. The Office of Space Commerce within the U.S. Department of Commerce also worked with SpaceX to understand and assess the Starlink screening service.
Quicker Response to Changes on Earth
The time it takes to plan maneuvers in today’s orbital traffic environment limits the number of satellites a human operator can manage and their ability to collect data or serve customers.
“A fully automated system that is flexible and adaptable between satellite constellations is ideal for an environment of multiple satellite operators, all of whom have differing criteria for mitigating collision risks,” said Lauri Newman, program officer for NASA’s Conjunction Assessment Risk Analysis program at the agency’s headquarters in Washington.
Reducing the time necessary to plan maneuvers could open up a new class of missions, where quick responses to changes in space or on Earth’s surface are possible. Satellites capable of making quicker movements could adjust their orbital position to capture a natural disaster from above, or respond to one swarm member’s interesting observations, moving to provide a more thorough look.
“With improved access and use of low Earth orbit and the necessity to provide a more advanced space traffic coordination system, Starling 1.5 is providing critical data. Starling 1.5 is the result of a successful partnership between NASA, the Department of Commerce, and SpaceX, maturing technology to solve such challenges,” said Roger Hunter, program manager of the Small Spacecraft Technology program. “We look forward to the sustained impact of the Starling technologies as they continue demonstrating advancements in spacecraft coordination, cooperation, and autonomy.”
NASA Ames leads the Starling projects. NASA’s Small Spacecraft Technology program within the Space Technology Mission Directorate funds and manages the Starling mission.
