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.NASA plans to return humans to the lunar surface in the coming decade.NASA Goddard 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 However, many professionals in the field are beginning to acknowledge that these requirements stem from outdated assumptions.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.John McFall stands by a mock-up of the SpaceX Dragon crew capsule.SpaceX, CC BY-NC-SA 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.On longer missions, astronauts may need to troubleshoot issues on their own.NASA 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.Jesse Rhoades, Professor of Education, Heath & Behavior, University of North Dakota and Rebecca Rhoades, Researcher in Education, Health & Behavior, University of North Dakota This article is republished from The Conversation under a Creative Commons license.

Why can’t I wiggle my toes one at a time, like my fingers?
why can’t I wiggle my toes? Ever wondered why you can’t wiggle your toes one at a time like your fingers? Learn how evolution, muscles, and your brain all play a part in making fingers more independent than toes—and why that’s key for walking and balance.
Why can’t I wiggle my toes individually, like I can with my fingers? – Vincent, age 15, Arlington, Virginia
One of my favorite activities is going to the zoo where I live in Knoxville when it first opens and the animals are most active. On one recent weekend, I headed to the chimpanzees first. Their breakfast was still scattered around their enclosure for them to find. Ripley, one of the male chimpanzees, quickly gathered up some fruits and vegetables, sometimes using his feet almost like hands. After he ate, he used his feet to grab the fire hoses hanging around the enclosure and even held pieces of straw and other toys in his toes. I found myself feeling a bit envious. Why can’t people use our feet like this, quickly and easily grasping things with our toes just as easily as we do with our fingers? I’m a biological anthropologist who studies the biomechanics of the modern human foot and ankle, using mechanical principles of movement to understand how forces affect the shape of our bodies and how humans have changed over time. Your muscles, brain and how human feet evolved all play a part in why you can’t wiggle individual toes one by one.Chimpanzee hands and feet do similar jobs.Manoj Shah/Stone via Getty Images
Comparing humans to a close relative
Humans are primates, which means we belong to the same group of animals that includes apes like Riley the chimp. In fact, chimpanzees are our closest genetic relatives, sharing almost 98.8% of our DNA. Evolution is part of the answer to why chimpanzees have such dexterous toes while ours seem much more clumsy. Our very ancient ancestors probably moved around the way chimpanzees do, using both their arms and legs. But over time our lineage started walking on two legs. Human feet needed to change to help us stay balanced and to support our bodies as we walk upright. It became less important for our toes to move individually than to keep us from toppling over as we moved through the world in this new way.Feet adapted so we could walk and balance on just two legs.Karina Mansfield/Moment via Getty Images Human hands became more important for things such as using tools, one of the hallmark skills of human beings. Over time, our fingers became better at moving on their own. People use their hands to do lots of things, such as drawing, texting or playing a musical instrument. Even typing this article is possible only because my fingers can make small, careful and controlled movements. People’s feet and hands evolved for different purposes.
Muscles that move your fingers or toes
Evolution brought these differences about by physically adapting our muscles, bones and tendons to better support walking and balance. Hands and feet have similar anatomy; both have five fingers or toes that are moved by muscles and tendons. The human foot contains 29 muscles that all work to help you walk and stay balanced when you stand. In comparison, a hand has 34 muscles. Most of the muscles of your foot let you point your toes down, like when you stand on tiptoes, or lift them up, like when you walk on your heels. These muscles also help feet roll slightly inward or outward, which lets you keep your balance on uneven ground. All these movements work together to help you walk and run safely. The big toe on each foot is special because it helps push your body forward when you walk and has extra muscles just for its movement. The other four toes don’t have their own separate muscles. A few main muscles in the bottom of your foot and in your calf move all four toes at once. Because they share muscles, those toes can wiggle, but not very independently like your fingers can. The calf muscles also have long tendons that reach into the foot; they’re better at keeping you steady and helping you walk than at making tiny, precise movements.Your hand is capable of delicate movements thanks to the muscles and ligaments that control its bones.Henry Gray, ‘Anatomy of the Human Body’/Wikimedia Commons, CC BY In contrast, six main muscle groups help move each finger. The fingers share these muscles, which sit mostly in the forearm and connect to the fingers by tendons. The thumb and pinky have extra muscles that let you grip and hold objects more easily. All of these muscles are specialized to allow careful, controlled movements, such as writing. So, yes, I have more muscles dedicated to moving my fingers, but that is not the only reason I can’t wiggle my toes one by one.
Divvying up brain power
You also need to look inside your brain to understand why toes and fingers work differently. Part of your brain called the motor cortex tells your body how to move. It’s made of cells called neurons that act like tiny messengers, sending signals to the rest of your body. Your motor cortex devotes many more neurons to controlling your fingers than your toes, so it can send much more detailed instructions to your fingers. Because of the way your motor cortex is organized, it takes more “brain power,” meaning more signals and more activity, to move your fingers than your toes.The motor cortex of your brain sends orders to move parts of your body.Kateryna Kon/Science Photo Library via Getty Images Even though you can’t grab things with your feet like Ripley the chimp can, you can understand why.Hello, curious kids!

Why do people get headaches? – Evie V., age 10, Corpus Christi, Texas
Whether sharp and stabbing or dull and throbbing, a headache can ruin your day. But your brain doesn’t actually feel pain. So what is going on when it feels like your head is in a vise or about to explode? I am a child neurologist – that is, a doctor who specializes in diseases of the brain in kids. Most of my patients are kids and adolescents who are struggling with headaches. Head pain is complicated, and there is still a lot to learn about what causes it and how it can be treated. But researchers know there are a few key players that take part in generating pain.
What are headaches?
Nerves communicate information like pain through electrical signals between the body and the brain. While the brain itself doesn’t have any nerve sensors to feel pain, blood vessels in the head and structures that protect and surround the brain do sense pain. When these tissues detect injury or damage, they release chemicals that trigger transmission of electrical signals through nerves to tell the brain the head is hurting. The brain will also use nerves to signal the body to respond to pain with symptoms like feeling tired, teary eyes, runny nose, upset stomach and discomfort in bright or loud environments. It’s not clear why humans evolved to feel these symptoms, but some scientists theorize that this can lead to healthier lifestyle choices to decrease the chance of future headache attacks.Weather changes are one of the most commonly reported migraine triggers. Danielle Wilhour, a neurologist and headache specialist at University of Colorado Anschutz Medical Campus, explains why shifts in weather can bring on migraines — and what you can do to ease the pain.
What causes headaches?
Often, headaches are a sign that the body is under some kind of stress. That stress triggers chemical and physical changes to the nerves and blood vessels around your brain, head and neck that can cause headaches. Many types of stresses can cause headaches, including an infection, allergies, hormone changes during puberty and menstrual cycles, not getting enough sleep, not drinking enough water, skipping meals or drinking too much caffeine or alcohol. Sometimes, headaches happen with emotional stress, like feeling anxious or depressed. Even pressure in your sinuses due to changes in the weather can cause your head to hurt. One in 11 kids have had a type of severe headache called a migraine. They feel like a pulsing and pounding pain in your head and come with other symptoms, including nausea or being sensitive to lights and sounds. During a migraine, it can be hard to do everyday activities because they can make the pain worse. It is also very common to feel unwell or irritable before the head pain starts and after the pain is gone.Migraines and chronic headaches can be debilitating.Viktoriya Skorikova/Moment via Getty Images Migraines occur when the nerves and other structures used in signaling and interpreting pain aren’t working properly, leading to pain and discomfort from stimulation that wouldn’t normally provoke this. There are many environmental and genetic factors that contribute to this dysfunction. Some people are born with a higher risk of developing migraines. Most people with migraines have someone in their family who also experiences them.
What can treat and prevent headaches?
Identifying what type of headache you’re experiencing is crucial to making sure it is treated properly. Because migraines can be severe, they’re the type of headache that most often leads to doctor’s visits for both kids and adults. There are several ways to reduce your chances of having headaches, such as drinking plenty of water and limiting caffeine. Eating, sleeping and exercising regularly are other ways you can help prevent headaches.Sleep deprivation can worsen headaches.DjelicS/iStock via Getty Images Plus While painkillers like ibuprofen are often enough to relieve a headache, prescription medications are sometimes necessary to make head pain more bearable. Some medications can also help control or prevent headache episodes. Physical therapy to exercise the body or behavioral therapy to work on the mind can also help you manage headache pain. There are even electronic devices to treat headaches by stimulating different parts of the nervous system. It is important to talk with a doctor about headaches, especially if it’s a new problem or you experience a change in how they usually feel. Sometimes, brain imaging or blood tests are needed to rule out another health issue. Recognizing a headache problem early will help your doctor get started on helping you figure out the best way to treat it.Hello, curious kids! Do you have a question you’d like an expert to answer?

Fact Check: Did Mike Rogers Admit the Travis Walton UFO Case Was a Hoax?
A fact check of viral claims that Mike Rogers admitted the Travis Walton UFO case was a hoax. We examine the evidence, the spotlight theory, and what the record actually shows.
In recent years, viral YouTube videos and podcast commentary have revived claims that the 1975 Travis Walton UFO abduction case was an admitted hoax. One of the most widely repeated allegations asserts that Mike Rogers, the logging crew’s foreman, supposedly confessed that he and Walton staged the entire event using a spotlight from a ranger tower to fool their coworkers.
So, is there any truth to this claim?
After reviewing decades of interviews, skeptical investigations, and public records, the answer is clear:
There is no verified evidence that Mike Rogers ever admitted the Travis Walton incident was a hoax.
Where the Viral Claim Comes From
The “confession” story has circulated for years in online forums and was recently amplified by commentary-style YouTube and podcast content, including popular personality-driven shows. These versions often claim:
Rogers and Walton planned the incident in advance
A spotlight from a ranger or observation tower simulated the UFO
The rest of the crew was unaware of the hoax
Rogers later “admitted” this publicly
However, none of these claims are supported by primary documentation.
What the Documented Record Shows
No Recorded Confession Exists
There is no audio, video, affidavit, court record, or signed statement in which Mike Rogers admits staging the incident.
Rogers has repeatedly denied hoax allegations in interviews spanning decades.
Even prominent skeptical organizations do not cite any confession by Rogers.
If such an admission existed, it would be widely referenced in skeptical literature and would have effectively closed the case. It has not.
The “Ranger Tower Spotlight” Theory Lacks Evidence
No confirmed ranger tower or spotlight installation matching the claim has been documented at the location.
No ranger, third party, or equipment operator has ever come forward.
No physical evidence or corroborating testimony supports this explanation.
Even professional skeptics typically label this idea as speculative, not factual.
Why Skepticism Still Exists (Legitimately)
While the viral claim lacks evidence, skepticism about the Walton case is not unfounded. Common, well-documented critiques include:
Financial pressure tied to a logging contract
The limitations and inconsistency of polygraph testing
Walton’s later use of hypnosis, which is controversial in memory recall
Possible cultural influence from 1970s UFO media
Importantly, none of these critiques rely on a confession by Mike Rogers, because none exists.

Updates & Current Status of the Case
As of today:
No new witnesses have come forward to confirm a hoax
No participant has recanted their core testimony
No physical evidence has conclusively proven or disproven the event
Walton and Rogers have both continued to deny hoax allegations
The case remains unresolved, not debunked.
Why Viral Misinformation Persists
Online commentary formats often compress nuance into dramatic statements. Over time:
Speculation becomes repeated as “fact”
Hypothetical explanations are presented as admissions
Entertainment content is mistaken for investigative reporting
This is especially common with long-standing mysteries like the Walton case, where ambiguity invites exaggeration.
Viral Claims vs. Verified Facts
Viral Claim:
Mike Rogers admitted he and Travis Walton staged the UFO incident.
Verified Fact:
No documented confession exists. Rogers has consistently denied hoax claims.
Viral Claim:
A ranger tower spotlight was used to fake the UFO.
Advertisement
Verified Fact:
No evidence confirms a tower, spotlight, or third-party involvement.
Viral Claim:
The case was “officially debunked.”
Verified Fact:
No authoritative body has conclusively debunked or confirmed the incident.
Viral Claim:
All skeptics agree it was a hoax.
Verified Fact:
Even skeptical researchers acknowledge the absence of definitive proof.
Advertisement
Viral Claim:
Hollywood exposed the truth in Fire in the Sky.
Verified Fact:
The film significantly fictionalized Walton’s testimony for dramatic effect.
Bottom Line
❌ There is no verified admission by Mike Rogers
❌ There is no evidence of a ranger tower spotlight hoax
✅ There are legitimate unanswered questions about the case
✅ The incident remains debated, not solved
The Travis Walton story persists not because it has been proven — but because it has never been conclusively explained.
