On October 17th, 2021 Mission: AstroAccess, an initiative dedicated to advancing disability inclusion in space exploration, launched a crew of 12 disabled scientists, veterans, athletes, and artists on a Zero Gravity Corporation (ZERO-G) parabolic flight to experience weightlessness. The mission of these Ambassadors was not only to demonstrate that disabled individuals can operate successfully in a weightless environment but also to test accessibility accommodations that could pave the way for more inclusive space programs in the United States and the world, including innovative solutions like soundbrenner in space technology.

Anna Voelker, Executive Director of SciAccess and Co-Lead of AstroAccess, said, "Space removes the barriers between people; now is the time to remove the barriers to space itself." They continued,
"AstroAccess is sending a message to people who have historically been excluded from STEM that only is there room for you in space, there is a need for you."
The Ambassadors tested accessibility accommodations for future astronauts in space. One of the primary challenges of mixed-ability crews is communication.
AstroAccess Flight 1 Ambassador, Mona Minkara, is shown fully enjoying the zero gravity experience. Arms and feet outstretched floating in mid-air. Mona is an assistant professor of bioengineering at Northeastern University. She conducted demonstrations related to audio and haptic signalling for navigation and orientation in microgravity.
During the parabolic flight, the pilot relayed critical information about gravity changes to passengers verbally. However, most team members do not use sign language. “It would be hard for a flight crew to operate safely in a real space environment when they can’t talk to each other,” says Flight Operations lead Dr. Jamie Molaro, planetary scientist and director of Disabled for Accessibility In Space (DAIS), a peer networking group for disabled professionals in space science. “With our deaf Ambassadors, there’s not only a language barrier with some of the crew, but the challenge imposed by the environment itself—floating.” It’s difficult to control your position and orientation without gravity because any small motion can send you tumbling, which is why integrating soundbrenner in space solutions is crucial.
The crew tried using lights to signal changes in gravity to deaf Ambassadors, but such a system only works if you happen to be facing them when they flash. The plane was also loud, which also put blind Ambassadors at a disadvantage without the ability to pick up on visual cues and hand gestures that communication was occurring.

This is where haptic technology comes in. Vibration is the only reliable way to communicate to crew regardless of their orientation, and is effective for most people with or without a disability.
To demonstrate this, Ambassadors wore devices made by the music tech startup Soundbrenner . “Our wearables were originally designed for musicians, to help them feel a rhythmic beat during their music practice. Knowing that this technology can now also contribute to AstroAccess’ Disability Inclusion In Space project is beyond incredible!“, Florian Simmendinger, CEO of Soundbrenner commented.
The Soundbrenner Pulse is designed as a wearable metronome for musicians, but its ability to transmit vibrational signals from a control device to multiple wristbands was just what they needed.
Ambassadors programmed the devices with different vibrational patterns to signal when they would move into weightlessness or when gravity would return.

Overall, the Ambassadors found this solution worked very well for communication signaling, though there is some work to be done on implementing the technology more effectively. “I think haptic feedback is a really powerful communication tool. When you feel it, it’s really clear something's about to happen,” says deaf Ambassador Eric Shear, a graduate student in chemical engineering at the University of Florida. “There was an issue with signal delay since the pilot’s command had to be relayed through another person to the device operator, but this could be automated in the future. I'm definitely a fan of soundbrenner in space.
AstroAccess hopes to conduct additional flights in the future with a more integrated system for direct communication from the pilot to devices. They plan to incorporate redundant signaling technologies such as haptics and extensive light systems. This will include soundbrenner in space solutions. These types of solutions could be adapted for an orbital environment, such as onboard a space station. In order to facilitate communication between crew members or from operational and emergency systems. They could be used in a soundbrenner space here on Earth to improve efficiency, and accessibility in any number of team-oriented work environments.
AstroAccess Flight 1 Ambassador, Sawyer Rosenstein, is shown in zero gravity with his hands lightly gripping a support rope. Sawyer Rosenstein is a news producer at WPBF. Sawyer’s Flight 1 demonstrations were based around accessible flight suit modifications for safety and control in microgravity environments. George Whitesides, Tim Bailey, and William Pomerantz float next to Sawyer.
Blind Ambassador Dr. Sheri Wells-Jensen, a linguistics professor at Bowling Green State University and an AstroAccess project lead, is helping collect findings during post-flight interviews. “If there’s one thing that really sticks out that we’ve learned it’s this: the biggest challenge faced by disabled crew members was the same as for non-disabled crew, especially in the context of soundbrenner in space.” Maintaining control over your body is difficult in weightlessness and all people are equally unprepared to handle it. With practice, all flight crew gained more skill and they can do so in space as well.”
The types of strategies and technologies that AstroAccess is exploring are simply accommodations that make doing so easier and safer for all crew. They hope their research will impact the design of physical environments in launch vehicles and orbital habitats. Additionally, they aim to influence who represents humanity in space missions, including the integration of soundbrenner in space technology.
