Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Skydweller Aero solar-powered, autonomous aircraft flies above the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center during a September 2024 test operation. Skydweller Aero has an ongoing airspace agreement with NASA Stennis to conduct test flights of its aircraft in the area.Skydweller Aero NASA’s Stennis Space Center near Bay St. Louis, Mississippi, has entered into an agreement with Skydweller Aero Inc. for the company to operate its solar-powered autonomous aircraft in the site’s restricted airspace, a key step towards achieving a strategic center goal.
The Reimbursable Space Act agreement marks the first between NASA Stennis and a commercial company to utilize the south Mississippi center’s unique capabilities to support testing and operation of uncrewed systems.
“There are few locations like NASA Stennis that offer a secure location, restricted airspace and the infrastructure to support testing and operation of various uncrewed systems,” said NASA Stennis Director John Bailey. “Range operations is a critical area of focus as we adapt to the changing aerospace and technology landscape to grow into the future.”
NASA Stennis and Skydweller Aero finalized the agreement in late August, paving the way for the company to begin area test flights of its autonomous, uncrewed solar-powered aircraft, which features a wingspan greater than a 747 jetliner and is designed for long-duration flights. The company announced Oct. 1 it had completed an initial test flight campaign of the aircraft, including two test excursions totaling 16 and 22.5 hours.
NASA Stennis and Skydweller Aero began talks in the summer of 2023 when the company expressed interest in utilizing NASA Stennis airspace for its all-carbon fiber aircraft. The NASA Stennis area fits the company’s needs well since it provides ready access from Stennis International Airport to the Gulf of Mexico area. NASA Stennis airspace also provides a level of privacy for aircraft testing and operation.
“Access to the restricted airspace above NASA Stennis has been tremendously helpful to our uncrewed, autonomous flight operations,” said Barry Matsumori, president and chief operating officer of Skydweller Aero. “The opportunity to use the controlled environment above Stennis helps accelerate our efforts, allowing us to transition the aircraft in and out of civil airspace, while demonstrating its reliability and unblemished safety record to the FAA.”
Companies must be conducting public aircraft operations to use any restricted airspace. In this instance, Skydweller Aero is flying its aircraft in association with the U.S. Department of Defense, allowing for the Reimbursable Space Act agreement with NASA Stennis.
The agreement provides the company Federal Aviation Administration (FAA) authorization for future test flights in designated areas of the NASA Stennis buffer zone. It also represents a key step in the center’s effort to grow its range operations presence.
“This really opens the door for others to come here,” said Jason Peterson, NASA Stennis range officer. “There are requirements that must be met, but for those who meet them, NASA Stennis is an ideal location for test and flight operations.”
The FAA established restricted airspace at NASA Stennis in 1966 and approved its expansion in 2016. The expansion was necessary to conduct propulsion testing safely, accommodate U.S. Department of Defense missions, and support unmanned aerial systems activities.
Restricted airspace at NASA Stennis allows qualifying organizations to conduct various uncrewed flight activities. NASA Stennis personnel provide scheduling and range operation support, including reviews and evaluations to ensure safe flight operations. Processes are in place to ensure communication between aircraft operators, FAA air traffic controllers, and range safety personnel.
Peterson said he hopes the agreement with Skydweller Aero will clear the way for future collaborations as NASA Stennis continues to expand its customer-based operations. For instance, although Skydweller Aero is not located onsite, NASA Stennis is able to support ground operations for a variety of unmanned aircraft system takeoffs and landings.
Beyond that, the center also hopes to expand its operational capabilities to include marine and ground activities. In addition to a large geographic footprint, the center features a secure 7.5-mile waterway canal system for testing unmanned underwater or surface vehicles.

NASA researchers developed a Quiet Space Fan to reduce the noise inside crewed spacecraft, sharing the results with industry for potential use on future commercial space stations.
Controlling noise inside spacecraft helps humans talk to each other, hear alarms clearer, get restful sleep, and minimizes the risk of hearing loss. It is best to control the noise at the source, and in spacecraft the noise often comes from cabin ventilation and equipment cooling fans.
Since the earliest days of human spaceflight, there has been noise from the Environmental Control and Life Support System ventilation. NASA is working to design highly efficient and quiet fans by building on technology initially developed at the agency’s Glenn Research Center in Cleveland and sharing it with companies that are developing new spacecraft and space stations.
The Quiet Space Fan prototype, initially developed at Glenn, to reduce noise inside spacecraft.Credits: NASA “As NASA continues to support the design and development of multiple commercial space stations, we have intentional and focused efforts to share technical expertise, technologies, and data with industry,” said Angela Hart, manager of NASA’s Commercial Low Earth Orbit Development Program at the agency’s Johnson Space Center in Houston. “The Quiet Space Fan research is one more example of how we are actively working with private companies to foster the development of future destinations.”
The initial fan prototype was designed at Glenn in 2009 using tools developed for aircraft turbofan engines. The fan design size, flow rate – how much air the fan moves – and pressure rise – the increase in pressure across the fan – were designed similarly to the original Orion cabin fan design point (150 cubic feet per minute, 3.64 inches of water column). Acoustic measurements showed that the new design was approximately 10 decibels quieter than a similar-sized commercial off-the-shelf fan.
To take the research a step further, a larger fan was recently designed with almost twice the flow rate and pressure rise capability (250 cubic feet per minute, 7 inches of water column) compared to the initial prototype. For example, the original fan could provide enough airflow for a large car or van, and the larger fan could provide enough airflow for a house.
NASA’s quiet fan design aims to maintain high performance standards while significantly reducing everyday noise levels and can potentially be used on the International Space Station and future commercial destinations.
The Quiet Space Fan helps to control noise that often comes from cabin ventilation and equipment cooling fans, and the research is being shared with industry. Credits: NASA “This work will lead to significant benefits including volume and mass savings from noise controls that are no longer as large or needed at all, reduced system pressure loss from mufflers and silencers that don’t need to be as restrictive, reduced power draw because of the reduced system pressure loss and the highly efficient fan design, and satisfying spaceflight vehicle acoustic requirements to provide a safe and habitable acoustic environment for astronauts,” said Chris Allen, Acoustics Office manager at NASA Johnson.
Developing quieter fans is one of many efforts NASA is making to improve human spaceflight and make space exploration more innovative and comfortable for future missions to low Earth orbit. Helping private companies provide reliable and safe services at a lower cost will allow the agency to focus on Artemis missions to the Moon while continuing to use low Earth orbit as a training and proving ground for deep space missions.
