It’s Time to Rethink Who’s Best Suited for Space Travel

In 1961, a college student named David Myers traveled from Washington, DC, to the US Naval School of Aviation Medicine in Florida to take part in a new experiment. “I had a very limited understanding of what I was getting myself into,” Myers told me recently over email. “So I was extremely curious and mildly excited that first day.”

Rose Eveleth is an Ideas contributor at WIRED and the creator and host of Flash Forward , a podcast about possible (and not so possible) futures.

Now known as the Gallaudet Eleven, Myers and his colleagues were recruited from Gallaudet College (now Gallaudet University), a school for d/Deaf students. (“Big D” Deaf refers to Deaf culture and community, while “small d” deaf refers to people who don’t identify with that community.) Ten out of the 11 men had become deaf because of spinal meningitis, an infection of the fluid in the spinal cord. The infection ultimately damaged each man’s inner ear, including their vestibular system, which also happens to be the system that is mainly responsible for motion sickness. This made the men perfect test subjects for a space program that was trying to understand what might happen to people in places where the inner ear can’t sense up and down. “Through their endurance and dedication, the work of the Gallaudet Eleven made substantial contributions to the understanding of motion sickness and adaptation to spaceflight,” wrote Hannah Hotovy of the NASA History Division. Harry Larson, another one of the Gallaudet Eleven, put it this way: “We were different in a way they needed.”

It’s no secret that it’s incredibly difficult to become an astronaut. NASA’s selection process is notoriously rigorous—strict enough that it was the most plausible kind of place to set the movie Gattaca , where only the perfectly genetically engineered get to board rockets bound for space. Writer Tom Wolfe documented the space program’s strenuous astronaut training program in his book The Right Stuff .

The assumption has long been that this training is a necessity—traveling to space is a mentally and physically grueling endeavor. We need the strongest, smartest, most adaptable among us to go. But strength comes in many forms, as do smarts. And if you want to find people who are the very best at adapting to worlds not suited for them, you’ll have the best luck looking at people with disabilities, who navigate such a world every single day. Which has led disability advocates to raise the question: What actually is the right stuff?

"Crip bodies were built for space travel. Crip minds already push the outer limits,” Alice Wong, founder of the Disability Visibility Project, tweeted last year . “We already master usage of breathing apparatuses and can handle challenging situations.” Wong went on to coedit an issue of the literary magazine Deaf Poets Society called “ Crips in Space ” with writer and performer Sam de Leve.

Take, for example, people who use ostomy bags. Right now, pooping in space is actually an important technical challenge . During takeoff, landing, and spacewalks, astronauts wear diapers. While in the space station, they use a toilet that requires a fair amount of precision and training to use . Astronauts have told all kinds of stories about rogue poop, or situations in which the toilet has backed up or generally gone awry. In 2008, NASA spent $19 million on a Russian toilet for the International Space Station . None of this would be an issue for an astronaut with an ostomy bag. “I could plug into the wall and just empty the container that’s been collecting,” says Mallory K. Nelson, a disability design specialist who uses an ileostomy bag—a pouch that connects to her intestine and collects waste. “I’ve moved the output location of poop, which creates a lot more flexibility in the kind of systems I can have. I could attach it to a space suit.”

All the various devices and ways of moving the body in space are likely more familiar to people with disabilities than to able-bodied people.

Or consider movement in space. You’ve certainly seen videos of astronauts zipping around the space station using their arms and legs to push off surfaces and direct their motion. This is a type of movement that people who use wheelchairs and other mobility aids are already familiar with. In fact, the various devices and ways of moving the body in space are likely more familiar to people with disabilities than to able-bodied people. “We move our bodies in so many different ways, and the disabled community has an exuberant amount of options,” says Nelson, who is an amputee and who has used crutches, a wheelchair, a scooter, and a prosthetic to get around. Nelson even coined a term for this recently: transmobility, the idea that there are lots of ways to get around besides putting one foot in front of the other.

Nelson also points out that most astronauts have no prior experience relying on technology for their movement and lives, whereas people with disabilities do so every day. In a space suit, for a space walk, an astronaut has to be trained in how to move their body in unison with a piece of technology. They have to get used to the idea that, if that technology should fail, they could be in grave danger. This, again, is an experience people like Nelson live with every day. “I’m always moving my body in motion with another object. That’s all we do,” Nelson says.

Or take blind astronauts. In a piece for Scientific American , Sheri Wells-Jensen lays out the case for designing spaceships for blind space travelers:

“After all, in a serious accident, the first thing to go might be the lights! This generally means that the first thing a sighted astronaut must do for security is ensure visual access to the environment. He hunts for a flashlight, and if emergency lighting comes on, his eyes take a moment to adjust. Meanwhile, the blind astronaut is already heading toward the source of the problem. In the fire aboard the Russian Mir space station, in 1997, the crew struggled as smoke obscured their view. The blind astronaut, while still affected by the lack of good air, would not be bothered by either dim lighting or occluding smoke. She would accurately direct the fire extinguisher at the source of heat and noise.”

In the Mir fire that Wells-Jensen mentions , one of the problems that arose was the sighted astronauts’ inability to locate the fire extinguisher through the smoke. Had the ship been laid out with a blind participant in mind, there would have been a nonvisual signal already built in to such a critical piece of equipment.

Or consider d/Deaf astronauts once again. The Gallaudet Eleven were tapped for their immunity to motion sickness—John Glenn even reportedly said he was envious of their ability to withstand the tests without getting sick—but there are other reasons why bringing a d/Deaf astronaut along could be useful. “Studies have shown that using sign languages confers cognitive advantages in one's visual working memory, enhancing how we see, remember, and manipulate objects in our mind,” says Joseph Murray, a professor at Gallaudet University and the scholar behind the term Deaf Gain , the idea that deafness should not be considered a loss of something but, rather, a gain of a whole host of other things. “The challenge Deaf Gain offers for NASA and all workplaces is to rethink their automatic assumptions about deaf people's capabilities,” Murray says. “If there is a mission need for people with advanced spatial processing skills who do not get motion sick, then there are quite a few deaf people ready and willing to serve.”

And it’s not just on a trip to space that people with disabilities might have an advantage. Take a situation in which astronauts are going somewhere to settle: Able bodies might no longer behave the way we expect. “Humans have an environmental niche on Earth, like all other creatures do, and we exploit it in different ways,” says Ashley Shew , a professor at Virginia Tech. Mars, or even a space station, is nothing like that niche. “The conditions in which our bodies have grown up are so drastically different that our existence in space will be much more like being a disabled person on Earth than like being an abled person on Earth.” Who better to send than those who are used to navigating environments not built for them—those who experience that every day on Earth? “Disabled people will fare better in space because disabled people have learned to negotiate hostile situations in ways that able bodied people are completely unaware of,” Shew says. Wong agrees. “The way we communicate, function, and exist with our diverse bodyminds sets us up as ideal space explorers and ambassadors of Earth, ready to make first contact with sentient beings,” she told me.

Whether this will actually happen is hard to say. NASA didn’t respond to my request for comment on their astronaut selection policy (like all government agencies, NASA personnel are currently not working due to the government shutdown). Nor did Mars One or SpaceX. Online, Mars One has a whole page of qualifications for candidates for their proposed Mars mission , stating, “In general, normal medical and physiological health standards will be used” and disqualifying anybody without “normal range of motion and functionality in all joints,” anybody with less than 20/20 vision, and anybody who is deemed not “healthy.” NASA’s FAQ section says that “for maximum crew safety, each crewmember must be free of medical conditions that would either impair the person's ability to participate in, or be aggravated by, space flight, as determined by NASA physicians.”

Changing these requirements won’t be easy. Spacecraft are designed with certain assumptions about what kinds of bodies will be sitting in the seats and operating the controls . The opportunity to change those parameters is small and must be seized while ships are being designed, not down the road. Plus, many people with disabilities who might want to go to space can’t get access to the pipeline that delivers so many astronauts: “Astronauts come via the military and that’s a closed door for disabled individuals,” Myers says. “Those kinds of obstacles need to be removed for those individuals who are otherwise qualified.” And NASA itself has had no reason to rethink their stance, because no one has really pushed them to. Yet, that is.

But all that could change. In 2017, Johanna Lucht became the first Deaf engineer to work at NASA. Eddie Ndopu, a South African activist and humanitarian, has said he wants to be the first disabled person in space. He plans to book a flight on a commercial trip into space and deliver an address to the UN while he’s up there. ( MTV is slated to film the entire thing .) Julia Velasquez, a Deaf woman from California, has gone through many of the steps traditionally taken by astronauts —she’s interned at NASA, recently received her pilot’s license, and even lived in a simulated Mars colony in Hawaii.

When I asked Myers if he ever wished he could have been an astronaut, he said, “Yes, absolutely. At one point I told Dr. Graybiel, ‘If you ever develop an experiment involving a flight into space, I want to be first in line.’” Myers likely won’t wind up in space in his lifetime. But he might live to see a disabled person make the journey, opening up space to a whole new set of uniquely qualified astronauts.
