Astronauts can get motion sick while splashing back down to Earth – virtual reality headsets could help them stay sharp
Spaceflight induces motion sickness due to discrepancies between brain expectations and actual gravitational experiences. While astronauts initially cope with space motion sickness, they may face terrestrial readaptation motion sickness upon return. Visual sensory manipulation techniques may offer non-pharmaceutical solutions to this issue.
When learning about the effects of spaceflight on human health, you typically will hear about the dangers of radiation, bone density loss and changes in eyesight. While these long-term risks are important, a less frequently discussed concern is motion sickness.
As a child, one of us (Taylor) was highly prone to motion sickness – whether in the backseat of a car, sitting on a train or riding a bus. At the time, she considered it a cruel twist of fate, but as an adult – and a scientist to boot – Taylor can tell you with confidence that it was entirely her fault.
You see, like most children during long car rides, Taylor would get bored. So, to combat this boredom, she would either read a book or play on her Gameboy. She would stare down at whatever form of entertainment was in her lap that day until the familiar creeping sensation of nausea developed.
Sometimes, looking out the side window would help, but more often than not, Taylor’s dad would have to pull over at the next gas station for a short break, or else they’d all suffer the consequences.
Now, she understands what was happening on a more fundamental level. As children, you are taught about the five senses: sight, hearing, smell, taste and touch. However, there is a hidden sixth sense that helps your body understand how you are moving – the vestibular system. The brain takes information from all these senses and compares it to what it might expect when moving, based on past experiences.
Optimally, any disagreement between your vestibular senses and your brain’s expectations would be small. But when there are large, sustained conflicts, you get sick.
While reading in the car, Taylor was staring at nonmoving words on a page while her vestibular system told her brain she was traveling down a road. This discrepancy confused her brain since usually, when Taylor felt movement, she should see the world shifting around her in the same way – hence her motion sickness. Had she been looking out the window and watching the world pass by, she would have been fine. Even better, had she been in the front seat, she would have been able to see the road ahead and predict how she would move in the future.Looking out the front window while driving can help mitigate motion sickness by aligning your vestigial senses with how your brain expects to be moving.

To date, all astronauts have grown up on Earth. So, their brains expect any motion cues to include the presence of Earth’s gravity. But when they get to orbit in space, that is no longer the case.
When in orbit around Earth in microgravity, the vestibular system does not have any gravitational input. The conflict between the brain’s expectation of Earth’s gravity and the reality of no gravity causes space motion sickness.

Thankfully, the brain’s expectations can change over time, after enough exposure to a new environment. Often referred to as “getting your sea legs” in the nautical community, astronauts also eventually overcome space motion sickness while in space. However, overcoming it introduces another problem when they return.
If an astronaut’s brain expects microgravity, what happens when they come back to Earth? As you might expect, the process starts again, and astronauts are now prone to terrestrial readaptation motion sickness. To make matters worse, since the retirement of the space shuttle, crew vehicles frequently land in the water, which means astronauts may deal with choppy waves until their capsule is recovered. Seasickness can potentially exacerbate terrestrial readaptation motion sickness.Crew capsules splash down into the ocean, which can exacerbate motion sickness. Anthony W. Gray/Kennedy Space Center
These conditions are not rare. Over half of all astronauts experience some symptoms of space motion sickness when they first get to space, and terrestrial readaptation motion sickness occurs at a similar incidence rate when they come back down.
Dangers to astronauts
If you have ever experienced motion sickness, you know how hard it is to do anything other than close your eyes and take deep breaths to expel the creeping urge to vomit. As a passenger in a car, that may be OK, since you aren’t expected to jump into action at a moment’s notice. But while isolated on the water in a return capsule, astronauts need to remain focused and clearheaded. In case of an emergency, they’ll need to respond rapidly.
If the astronauts need to get out of the capsule prior to pickup up by the recovery team, any motion sickness they have could delay their response time and impede evacuation attempts.
Potential solutions
Presently, most astronauts rely on medication that interrupts the brain’s ability to use hormones to trigger motion sickness. However, as with many commercial products, these drugs can cause side effects such as drowsiness and can lose efficacy over time.
Our research team completed two experiments to investigate how we might be able to manipulate visual information to mitigate motion sickness in astronauts, without relying on pharmaceuticals.
When in a capsule on the ocean, astronauts are strapped into their seats and likely cannot see out of the small windows built into the capsule. In place of windows, we used virtual reality headsets to create a full-view virtual window.
In our control group, the subjects received no visual cues of motion – akin to Taylor’s poorly advised backseat reading. Meanwhile, one countermeasure group got to see a visual scene that moved naturally with their motion, like looking out the side window of the car at the surrounding world. The other countermeasure group saw a scene that moved appropriately and was provided an overlay showing future motion, like looking out the front window and seeing the road ahead. https://www.youtube.com/embed/X3Aijwo_diU?wmode=transparent&start=0 The device moving in a wavelike motion.
As expected, the group with no cues of motion got the sickest. Two-thirds of the subjects needed to stop prior to finishing an hour of wavelike motion, due to excessive nausea. Only about one-fifth of the group that was given the side window view needed to stop early. Only one-tenth of the front window group that received present and future visual cues dropped out.
These results mean that by tracking the capsule motion and projecting it on a headset for the astronauts inside, our team may be able to reduce debilitating motion sickness by roughly half. If we could figure out how to predict how the capsule would move, we could give them that front window experience and improve the landing even more. In case of emergency, they could always take off the headsets.

This work shows promise for motion sickness interventions that do not rely on pharmaceuticals, which are currently used to combat these effects. Our solutions don’t have the same concerns around shelf life, stability or side effects. In addition to the benefits for astronauts, such approaches could help those prone to motion sickness here on Earth, particularly in scenarios where looking out the front window at the road isn’t feasible, such as on planes, trains, buses or high-speed transportation.

NASA goes on an ESCAPADE – twin small, low-cost orbiters will examine Mars’ atmosphere
NASA’s ESCAPADE mission launched two small, affordable orbiters to Mars on Blue Origin’s New Glenn rocket. Discover how these twin spacecraft will study Mars’ atmosphere, test new trajectories, and usher in a new era of rapid, low-cost space exploration.
NASA goes on an ESCAPADE – twin small, low-cost orbiters will examine Mars’ atmosphere
Christopher Carr, Georgia Institute of Technology and Glenn Lightsey, Georgia Institute of Technology Envision a time when hundreds of spacecraft are exploring the solar system and beyond. That’s the future that NASA’s ESCAPADE, or Escape and Plasma Acceleration and Dynamics Explorers, mission will help unleash: one where small, low-cost spacecraft enable researchers to learn rapidly, iterate, and advance technology and science. The ESCAPADE mission launched on Nov. 13, 2025 on a Blue Origin New Glenn rocket, sending two small orbiters to Mars to study its atmosphere. As aerospace engineers, we’re excited about this mission because not only will it do great science while advancing the deep space capabilities of small spacecraft, but it also will travel to the red planet on an innovative new trajectory. The ESCAPADE mission is actually two spacecraft instead of one. Two identical spacecraft will take simultaneous measurements, resulting in better science. These spacecraft are smaller than those used in the past, each about the size of a copy machine, partly enabled by an ongoing miniaturization trend in the space industry. Doing more with less is very important for space exploration, because it typically takes most of the mass of a spacecraft simply to transport it where you want it to go.The ESCAPADE mission logo shows the twin orbiters.TRAX International/Kristen Perrin Having two spacecraft also acts as an insurance policy in case one of them doesn’t work as planned. Even if one completely fails, researchers can still do science with a single working spacecraft. This redundancy enables each spacecraft to be built more affordably than in the past, because the copies allow for more acceptance of risk.
Space is not a friendly place. Most of it is a vacuum – that is, mostly empty, without the gas molecules that create pressure and allow you to breathe or transfer heat. These molecules keep things from getting too hot or too cold. In space, with no pressure, a spacecraft can easily get too hot or too cold, depending on whether it is in sunlight or in shadow. In addition, the Sun and other, farther astronomical objects emit radiation that living things do not experience on Earth. Earth’s magnetic field protects you from the worst of this radiation. So when humans or our robotic representatives leave the Earth, our spacecraft must survive in this extreme environment not present on Earth. ESCAPADE will overcome these challenges with a shoestring budget totaling US$80 million. That is a lot of money, but for a mission to another planet it is inexpensive. It has kept costs low by leveraging commercial technologies for deep space exploration, which is now possible because of prior investments in fundamental research. For example, the GRAIL mission, launched in 2011, previously used two spacecraft, Ebb and Flow, to map the Moon’s gravity fields. ESCAPADE takes this concept to another world, Mars, and costs a fraction as much as GRAIL. Led by Rob Lillis of UC Berkeley’s Space Sciences Laboratory, this collaboration between spacecraft builders Rocket Lab, trajectory specialists Advanced Space LLC and launch provider Blue Origin – all commercial partners funded by NASA – aims to show that deep space exploration is now faster, more agile and more affordable than ever before.NASA’s ESCAPADE represents a partnership between a university, commercial companies and the government.
How will ESCAPADE get to Mars?
ESCAPADE will also use a new trajectory to get to Mars. Imagine being an archer in the Olympics. To hit a bull’s-eye, you have to shoot an arrow through a 15-inch – 40-centimeter – circle from a distance of 300 feet, or 90 meters. Now imagine the bull’s-eye represents Mars. To hit it from Earth, you would have to shoot an arrow through the same 15-inch bull’s-eye at a distance of over 13 miles, or 22 kilometers. You would also have to shoot the arrow in a curved path so that it goes around the Sun. Not only that, but Mars won’t be at the bull’s-eye at the time you shoot the arrow. You must shoot for the spot that Mars will be in 10 months from now. This is the problem that the ESCAPADE mission designers faced. What is amazing is that the physical laws and forces of nature are so predictable that this was not even the hardest problem to solve for the ESCAPADE mission. It takes energy to get from one place to another. To go from Earth to Mars, a spacecraft has to carry the energy it needs, in the form of rocket fuel, much like gasoline in a car. As a result, a high percentage of the total launch mass has to be fuel for the trip. When going to Mars orbit from Earth orbit, as much as 80% to 85% of the spacecraft mass has to be propellant, which means not much mass is dedicated to the part of the spacecraft that does all the experiments. This issue makes it important to pack as much capability into the rest of the spacecraft as possible. For ESCAPADE, the propellant is only about 65% of the spacecraft’s mass. ESCAPADE’s route is particularly fuel-efficient. First, Blue and Gold will go to the L2 Lagrange point, one of five places where gravitational forces of the Sun and Earth cancel out. Then, after about a year, during which they will collect data monitoring the Sun, they will fly by the Earth, using its gravitational field to get a boost. This way, they will arrive at Mars in about 10 more months. This new approach has another advantage beyond needing to carry less fuel: Trips from Earth to Mars are typically favorable to save fuel about every 26 months due to the two planets’ relative positions. However, this new trajectory makes the departure time more flexible. Future cargo and human missions could use a similar trajectory to have more frequent and less time-constrained trips to Mars. ESCAPADE is a testament to a new era in spaceflight. For a new generation of scientists and engineers, ESCAPADE is not just a mission – it is a blueprint for a new collaborative era of exploration and discovery. This article was updated on Nov. 13, 2025 to reflect the ESCAPADE launch’s date and success.Christopher Carr, Assistant Professor of Aerospace Engineering, Georgia Institute of Technology and Glenn Lightsey, Professor of Space Systems Technology, Georgia Institute of Technology This article is republished from The Conversation under a Creative Commons license.
