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.

NASA also offers apps that provide interactive experiences with two major areas of space station research: plant growth and human health.
Screenshot from the NASA Science Investigations: Plant Growth app On the NASA Science Investigations: Plant Growth app, your task as the newest member of the crew is to familiarize yourself with the interior of the station, which is the size of a five-bedroom house and contains a wide variety of equipment and tools. Once you are ready, help with a plant growth experiment, conducting tasks such as watering, trimming, and analyzing plant growth. Future missions need the ability to grow plants in space to provide fresh food for crew members and to contribute to life support systems, and the space station has hosted multiple experiments working toward this goal. Researchers have grown lettuces, Chinese cabbage, mustard greens, kale, tomatoes, radishes, and chile peppers on orbit. Now it’s your turn!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA operations engineer Daniel Velasquez, left, is reviewing the Mobile Vertipad Sensor Package system as part of the Air Mobility Pathways test project at NASA’s Armstrong Flight Research Center in Edwards, California, on Oct. 17, 2023.NASA/Steve Freeman Lee esta historia en Español aquí.
Born and raised in Peru, Daniel Velasquez moved to the United States when was 10 years old. While that decision was a big transition for his family, it also created many opportunities for him. Now Velasquez is an operations engineer for NASA’s Air Mobility Pathfinders project at NASA’s Armstrong Flight Research Center in Edwards, California.
Velasquez develops flight test plans for electric vertical take-off and landing (eVTOL) aircraft, specifically testing how they perform during various phases of flight, such as taxi, takeoff, cruise, approach, and landing. He was drawn to NASA Armstrong because of the legacy in advancing flight research and the connection to the Space Shuttle program.
“Being part of a center with such a rich history in supporting space missions and cutting-edge aeronautics was a major motivation for me,” Velasquez said. “One of the biggest highlights of my career has been the opportunity to meet (virtually) and collaborate with an astronaut on a possible future NASA project.”
Daniel Velasquez stands next to the main entrance sign at NASA’s Armstrong Flight Research Center in Edwards, California, in 2022.Daniel Velasquez Velasquez is incredibly proud of his Latino background because of its rich culture, strong sense of community and connection to his parents. “My parents are my biggest inspiration. They sacrificed so much to ensure my siblings and I could succeed, leaving behind the comfort of their home and family in Peru to give us better opportunities,” Velasquez said. “Their hard work and dedication motivate me every day. Everything I do is to honor their sacrifices and show them that their efforts weren’t wasted. I owe all my success to them.”
Velasquez began his career at NASA in 2021 as an intern through the Pathways Internship Program while he was studying aerospace engineering at Rutgers University in New Brunswick, New Jersey. Through that program, he learned about eVTOL modeling software called NASA Design and Analysis of Rotorcraft to create a help guide for other NASA engineers to reference when they worked with the software.
At the same time, he is also a staff sergeant in the U.S Army Reserves and responsible for overseeing the training and development of junior soldiers during monthly assemblies. He plans, creates, and presents classes for soldiers to stay up-to-date and refine their skills while supervising practical exercises, after action reviews, and gathering lessons learned during trainings.
Daniel Velasquez graduated in 2023 from Rutgers University in New Jersey while he was an intern at NASA. Behind him is the New York City skyline.Daniel Velasquez “This job is different than what I do day-to-day at NASA, but it has helped me become a more outspoken individual,” he said. “Being able to converse with a variety of people and be able to do it well is a skill that I acquired and refined while serving my country.”
Velasquez said he never imagined working for NASA as it was something he had only seen in movies and on television, but he is so proud to be working for the agency after all the hard work and sacrifices he made that lead him to this point. “I am incredibly proud to work every day with some of the most motivated and dedicated individuals in the industry.”
