Jesse Rhoades, University of North Dakota and Rebecca Rhoades, University of North Dakota Humans will likely set foot on the Moon again in the coming decade. While many stories in this new chapter of lunar exploration will be reminiscent of the Apollo missions 50 years ago, others may look quite different. For instance, the European Space Agency is currently working to make space travel more accessible for people of a wide range of backgrounds and abilities. In this new era, the first footprint on the Moon could possibly be made by a prosthetic limb.

Historically, and even still today, astronauts selected to fly to space have had to fit a long list of physical requirements. However, many professionals in the field are beginning to acknowledge that these requirements stem from outdated assumptions. Some research, including studies by our multidisciplinary team of aerospace and biomechanics researchers, has begun to explore the possibilities for people with physical disabilities to venture into space, visit the Moon and eventually travel to Mars.

Current research

NASA has previously funded and is currently funding research on restraints and mobility aids to help everyone, regardless of their ability, move around in the crew cabin. Additionally, NASA has research programs to develop functional aids for individuals with disabilities in current U.S. spacecraft. A functional aid is any device that improves someone’s independence, mobility or daily living tasks by compensating for their physical limitations. The European Space Agency, or ESA, launched its Parastronaut Feasibility Project in 2022 to assess ways to include individuals with disabilities in human spaceflight. A parastronaut is an astronaut with a physical disability who has been selected and trained to participate in space missions. At the University of North Dakota, we conducted one of the first studies focused on parastronauts. This research examined how individuals with disabilities get into and get out of two current U.S. spacecraft designed to carry crew. The first was NASA’s Orion capsule, designed by Lockheed Martin, and the second was Boeing’s CST 100 Starliner. Alongside our colleagues Pablo De León, Keith Crisman, Komal Mangle and Kavya Manyapu, we uncovered valuable insights into the accessibility challenges future parastronauts may face. Our research indicated that individuals with physical disabilities are nearly as nimble in modern U.S. spacecraft as nondisabled individuals. This work focused on testing individuals who have experienced leg amputations. Now we are looking ahead to solutions that could benefit astronauts of all abilities.

Safety and inclusion

John McFall is the ESA’s first parastronaut. At the age of 19, Mcfall lost his right leg just above the knee from a motorcycle accident. Although McFall has not been assigned to a mission yet, he is the first person with a physical disability to be medically certified for an ISS mission.

Astronaut selection criteria currently prioritize peak physical fitness, with the goal of having multiple crew members who can do the same physical tasks. Integrating parastronauts into the crew has required balancing mission security and accessibility. However, with advancements in technology, spacecraft design and assistive tools, inclusion no longer needs to come at the expense of safety. These technologies are still in their infancy, but research and efforts like the ESA’s program will help improve them. Design and development of spacecraft can cost billions of dollars. Simple adaptations, such as adding handholds onto the walls in a spacecraft, can provide vital assistance. However, adding handles to existing spacecraft will be costly. Functional aids that don’t alter the spacecraft itself – such as accessories carried by each astronaut – could be another way forward. For example, adding Velcro to certain spots in the spacecraft or on prosthetic limbs could improve a parastronaut’s traction and help them anchor to the spacecraft’s surfaces. Engineers could design new prosthetics made for particular space environments, such as zero or partial gravity, or even tailored to specific spacecraft. This approach is kind of like designing specialized prosthetics for rock climbing, running or other sports.

Accessibility can help everyone

Future space exploration, particularly missions to the Moon and Mars that will take weeks, months and even years, may prompt new standards for astronaut fitness. During these long missions, astronauts could get injured, causing what can be considered incidental disability. An astronaut with an incidental disability begins a mission without a recognized disability but acquires one from a mission mishap. An astronaut suffering a broken arm or a traumatic brain injury during a mission would have a persistent impairment.

During long-duration missions, an astronaut crew will be too far away to receive outside medical help – they’ll have to deal with these issues on their own. Considering disability during mission planning goes beyond inclusion. It makes the mission safer for all astronauts by preparing them for anything that could go wrong. Any astronaut could suffer an incidental disability during their journey. Safety and inclusion in spaceflight don’t need to be at odds. Instead, agencies can reengineer systems and training processes to ensure that more people can safely participate in space missions. By addressing safety concerns through technology, innovative design and mission planning, the space industry can have inclusive and successful missions.

For years, some commentators have called for K-12 teachers to take on fake news, media literacy, or online misinformation by doubling down on critical thinking. This push for schools to do a better job preparing young people to differentiate between low- and high-quality information often focuses on social studies classes. As an education researcher and former high school history teacher, I know that there’s both good and bad news about combating misinformation in the classroom. History class can cultivate critical thinking – but only if teachers and schools understand what critical thinking really means.

Not just a ‘skill’

First, the bad news. When people demand that schools teach critical thinking, it’s not always clear what they mean. Some might consider critical thinking a trait or capacity that teachers can encourage, like creativity or grit. They could believe that critical thinking is a mindset: a habit of being curious, skeptical and reflective. Or they might be referring to specific skills – for instance, that students should learn a set of steps to take to assess information online. Unfortunately, cognitive science research has shown that critical thinking is not an abstract quality or practice that can be developed on its own. Cognitive scientists see critical thinking as a specific kind of reasoning that involves problem-solving and making sound judgments. It can be learned, but it relies on specific content knowledge and does not necessarily transfer between fields. Early studies on chess players and physicists in the 1970s and ’80s helped show how the kind of flexible and reflective cognition often called critical thinking is really a product of expertise. Chess masters, for instance, do not start out with innate talent. In most cases, they gain expertise by hours of thoughtfully playing the game. This deliberate practice helps them recognize patterns and think in novel ways about chess. Chess masters’ critical thinking is a product of learning, not a precursor.

Because critical thinking develops in specific contexts, it does not necessarily transfer to other types of problem-solving. For example, chess advocates might hope the game improves players’ intelligence, and studies do suggest learning chess may help elementary students with the kind of pattern recognition they need for early math lessons. However, research has found that being a great chess player does not make people better at other kinds of complex critical thinking.

Historical thinking

Since context is key to critical thinking, learning to analyze information about current events likely requires knowledge about politics and history, as well as practice at scrutinizing sources. Fortunately, that is what social studies classes are for. Social studies researchers often describe this kind of critical thinking as “historical thinking”: a way to evaluate evidence about the past and assess its reliability. My own research has shown that high school students can make relatively quick progress on some of the surface features of historical thinking, such as learning to check a text’s date and author. But the deep questioning involved in true historical thinking is much harder to learn. Social studies classrooms can also build what researchers call “civic online reasoning.” Fact-checking is complex work. It is not enough to tell young people that they should be wary online, or to trust sites that end in “.org” instead of “.com.” Rather than learning general principles about online media, civic online reasoning teaches students specific skills for evaluating information about politics and social issues. Still, learning to think like a historian does not necessarily prepare someone to be a skeptical news consumer. Indeed, a recent study found that professional historians performed worse than professional fact-checkers at identifying online misinformation. The misinformation tasks the historians struggled with focused on issues such as bullying or the minimum wage – areas where they possessed little expertise.

Powerful knowledge

That’s where background knowledge comes in – and the good news is that social studies can build it. All literacy relies on what readers already know. For people wading through political information and news, knowledge about history and civics is like a key in the ignition for their analytical skills. Readers without much historical knowledge may miss clues that something isn’t right – signs that they need to scrutinize the source more closely. Political misinformation often weaponizes historical falsehoods, such as the debunked and recalled Christian nationalist book claiming that Thomas Jefferson did not believe in a separation of church and state, or claims that the nadir of African American life came during Reconstruction, not slavery. Those claims are extreme, but politicians and policymakers repeat them. For someone who knows basic facts about American history, those claims won’t sit right. Background knowledge will trigger their skepticism and kick critical thinking into gear.

Past, present, future

For this reason, the best approach to media literacy will come through teaching that fosters concrete skills alongside historical knowledge. In short, the new knowledge crisis points to the importance of the traditional social studies classroom. But it’s a tenuous moment for history education. The Bush- and Obama-era emphasis on math and English testing resulted in decreased instructional time in history classes, particularly in elementary and middle schools. In one 2005 study, 27% of schools reported reducing social studies time in favor of subjects on state exams. Now, history teachers are feeling heat from politically motivated culture wars over education that target teaching about racism and LGBTQ+ issues and that ban books from libraries and classrooms. Two-thirds of instructors say that they’ve limited classroom discussions about social and political topics. Attempts to limit students’ knowledge about the past imperil their chances of being able to think critically about new information. These attacks are not just assaults on the history of the country; they are attempts to control its future.
