CUriosity: Can humans handle the stress of traveling to Mars? Jeff Zehnder Wed, 11/13/2024 - 14:42

In CUriosity, experts across the CU Boulder campus answer pressing questions about humans, our planet and the universe beyond.

This week, Katya Arquilla, assistant professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences, looks into the question: “Can humans handle the stress of traveling to Mars?”

In June, NASA astronauts Butch Wilmore and Suni Williams boarded the International Space Station (ISS), expecting a week-long stay in orbit. Now, they won’t return to Earth until February after a series of technical issues plagued the Boeing Starliner space capsule they rode into space on.

If spending eight months on the ISS, which measures just 5,000 square feet, sounds like a recipe for frayed nerves, it may very well be. That’s according to Arquilla, an engineer who has studied how long space journeys can affect the mental health of humans.

“On long-duration space missions, there are many stressors that create the potential for negative mental health effects,” she said. “From data taken in research facilities in extreme environments on Earth, like Antarctica, we have seen symptoms of depression, anxiety and stress.”

A future mission to Mars, however, could be a lot more than eight months, potentially as much as three years. Which raises the question: Can humans handle that much time in space?

Arquilla thinks so, but there are caveats.

“It will be a big challenge,” she said. “There’s a lot we don’t know because we haven’t sent people to Mars before. They won’t be able to look down and see the Earth the way they can on the International Space Station.”

In previous research, Arquilla and her colleagues explored the mental health consequences of that kind of isolation through an unlikely event here on Earth—the COVID-19 pandemic. In 2020, millions of Americans were suddenly cooped up in their homes with the threat of a major disease hanging over their heads. The researchers conducted a survey and observed that people with military training or other experience in stressful environments tended to be more productive during the pandemic than others. But those experienced individuals didn’t appear to maintain their mental health better than less experienced people.

Arquilla noted that simply being aware of your own body, and knowing when stress sets in, can help. She has partnered with Laura Devendorf, a researcher at CU Boulder’s ATLAS Institute, to assist people in doing that kind of monitoring. The team integrated sensors into comfortable textiles that track electrocardiogram (ECG) signals coming from wearers’ hearts.

“Maybe I'm an astronaut on a mission and I'm tracking my own signals, and I see that my heartrate starts to go up,” Arquilla said. “I could decide based on that that I should take a break for a couple of hours.”

This research won’t just help astronauts. Arquilla is also exploring how similar technologies could give people on the ground tools to detect and manage symptoms of mental health changes in high-stress environments. That might include wilderness expeditions, remote research facilities and military deployments.

She’s glad to see people talking more about mental health, both on Earth and in space.

“We all, after the pandemic, understand the importance of mental health a lot more than we did maybe 10 years ago,” she said. “Being able to recognize that it's okay to not feel at 100% all the time, and being able to give people the tools they need to articulate what is wrong, is really important.”

Katya Arquilla

Katya Arquilla is leading a major new NASA grant to mitigate the negative effects of communication delays on the performance of distributed teams for upcoming missions on the surface of the Moon.

Arquilla has earned a five-year, $1.5 million grant through NASA’s 2024 Human Exploration Research Opportunities program. With it, she is leading a multidisciplinary team to investigate countermeasures for radio transmission lags between the Earth and Moon as well as the length of time it takes astronauts to mentally process new instructions and act on them.

“There are communication delays inherent in lunar operations, not just due to the time it takes for a message to travel from Earth to the Moon, but also because of the time it takes people to work through their comprehension of task requirements and their environment. The delays are 5-14 seconds as a baseline, and it only goes up from there,” Arquilla said.

An assistant professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at the University of Colorado Boulder, Arquilla works in bioastronautics, particularly how humans interact with and adapt to complex systems.

NASA is planning an array of lengthy Moon missions over the next decade, potentially including a permanent base near the lunar south pole. Construction of such a facility and subsequent science missions will require long and complicated extravehicular activities, or moon walks, by astronauts. Such efforts can be trying under the best of conditions, and could be even more complex when astronauts are trying to follow elaborate instructions from team members in another location on the Moon or back on Earth.

“Communications become a real stressor if there is any lag time that causes overlapping communications or excessive wait time that wastes resources,” Arquilla said. “We are developing countermeasures to fill that lag time with productive actions, using approaches like autonomous chat bots and automated prompts that guide the human through aspects of the reasoning process.”

To test these countermeasures, the research team will develop a laboratory-based mission analog that will include distributed teams performing realistic tasks in a mockup habitat, rover, and mission control center with integrated communication delays. During testing, participants’ cognitive load and team performance will be measured with physiological sensors.

Following testing of potential countermeasures in the Bioastronautics Laboratory, the team will select the most promising solutions for full field tests at NASA’s Human Exploration Research Analog facility in Houston, Texas, where scientists conduct simulated space missions.

The project features researchers from multiple laboratories at CU Boulder as well as the Colorado School of Mines. In addition to Arquilla, the team includes Torin Clark and Allie Hayman, also from Smead Aerospace, Leanne Hirshfield from CU Boulder’s Institute of Cognitive Science, and Tom Williams from the Colorado School of Mines.

“This may be one of the first projects to do this kind of comprehensive distributed team simulation in the laboratory, and it’s a really cool collaborative opportunity that is going to be a great challenge. Good ideas don’t happen in a vacuum—we have a strong Bioastronautics team and collaborators with expertise in computer science and human cognition that led to our selection for this award,” Arquilla said.

Developing communications systems to help astronauts work better on the Moon could have an array of future benefits.

“It’s about improving communications during maintenance tasks, but also in problem situations that could threaten the rest of the crew when seconds count,” Arquilla said. “But anytime astronauts are outside the capsule, wearing a bulky space suit is a high stress, demanding situation. This is something that can make for a better experience.”

With Polaris Dawn’s launch, Colorado scientists will study vision changes in space

With Polaris Dawn’s launch, Colorado scientists will study vision changes in space Jeff Zehnder Mon, 09/16/2024 - 09:04

During SpaceX’s Polaris Dawn's multi-day high-altitude mission, which rocketed to space on Sept. 10, the crew will conduct health impact research to better understand spaceflight-associated neuro-ocular syndrome (SANS). Researchers from CU Boulder and the CU Anschutz Medical Campus are right there with them. Or at least their equipment and expertise will be.

The team is sending up specialized optical equipment to gather data from astronauts’ eyes and will analyze the results during and after the five-day mission.

The research is a collaboration between Allie Hayman, associate professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at CU Boulder, and Prem Subramanian, chief of neuro-ophthalmology at the CU School of Medicine.

Torin Clark, associate professor of aerospace engineering sciences at CU Boulder, is leading separate research from the ground for the Polaris Dawn mission about how astronauts experience motion sickness and other illusory sensations during space travel.

For some time, astronauts have noticed vision changes during long-duration space missions. Since 1998, NASA has sent astronauts to the International Space Station with “space anticipation glasses,” which have adjustable refraction settings to meet changing vision needs, similar to binoculars. In 2011, NASA began conducting MRI scans on astronauts following missions, which revealed potentially increased pressure in their brains as well as optic disc swelling, or papilledema, in more than half of the astronauts.

On Polaris Dawn, the researchers are sending up SENSIMED Triggerfish lenses, which are “smart” contact lenses to track eye pressure fluctuation and changes in cornea dimensions in glaucoma patients. CU Department of Ophthalmology Adjoint Professor Kaweh Mansouri, MD, contributed to the development of these lenses, which will monitor astronauts’ eyes during launch and as they transition to microgravity, a condition of apparent weightlessness. The lenses contain sensors that transmit data to an antenna and local storage device, enabling the researchers to collect and analyze data upon their return.

The team is also sending a device called the QuickSee, which will measure astronauts’ refractive error, when the shape of the eye changes and keeps light from focusing correctly on the retina.

Polaris Dawn crew members include Mission Commander Jared “Rook” Isaacman; Mission Pilot Scott “Kidd” Poteet; Mission Specialist and Medical Officer Anna “Walker” Menon; and Mission Specialist Sarah “Cooper” Gillis, who graduated from CU Boulder in 2017 with a degree in aerospace engineering sciences.

With space travel comes motion sickness. These engineers want to help

With space travel comes motion sickness. These engineers want to help Anonymous (not verified) Fri, 03/01/2024 - 14:50

In a corner room of the Aerospace Engineering Sciences Building at CU Boulder, Torin Clark is about to go for a ride.

The associate professor straps himself into what looks like an intimidating dentist’s chair perched on metal scaffolding, which, in turn, rests on a circular base. The whole set up resembles a carnival attraction.

Which, in a way, it is.

“Torin, are you ready to start?” calls out graduate student Taylor Lonner from in front of a monitor displaying several views of Clark. “I’m going to go to 5 r.p.m. over two minutes.”

Clark gives a thumbs up and begins to spin—first slowly, then faster and faster. The chair whips in circles around the room, creating a centrifugal force that forces his body back into the headrest.

Once the machine slows down and Clark is back on solid ground, he seems a little wobbly but in otherwise good spirits.

“It basically feels like a gravitron,” he says, referring to the spinning, nausea-inducing rides that became a staple of county fairs in the 1980s.

The team from the Ann and H.J. Smead Department of Aerospace Engineering Sciences is using this machine as one step in an experiment that seeks to recreate an experience that few people ever have: The shock of going from one gravity environment, like space, to another, like the surface of Earth. In particular, the group is tackling what happens when astronauts return home, landing in their spacecrafts in the middle of a choppy ocean.

Disorientation and motion sickness have long been an underappreciated reality of space exploration, Lonner said. Surveys suggest that a majority of astronauts and cosmonauts have gotten sick during water landings—a relatively minor condition that could become dangerous if nauseous crew members suddenly have to respond to a disaster.

Addressing such motion sickness will become increasingly important as more people travel into space, and stay there for long, Lonner said. In recent lab experiments, the team discovered that virtual reality goggles might help keep astronauts grounded when they splash down in the ocean. This technology can provide people with calming images of a landscape to gaze at, similar to watching the horizon from the deck of a boat.

The team presented its results this month at NASA’s annual Human Research Program Investigators’ Workshop in Galveston, Texas.

“We’re increasing this whole bubble of space exploration,” Lonner said. “But people aren’t going to want to do that if they’re just going to be miserable when they get to microgravity and when they return to Earth.”

Adrift at sea

For the aerospace engineer, the question is a personal one—she can’t so much as crack a book open during car rides without getting queasy. According to one hypothesis, motion sickness like hers arises from a sort of mismatch between the body and brain.

“When you’re in a moving environment, your body senses your surroundings, but your brain also holds an expectation for what you should be sensing based on your past experiences,” Lonner said. “When those two things disagree for an extended period of time, you get motion sick.”

Unfortunately for astronauts, space is full of those kinds of contradictions.

When humans first break free of Earth’s atmosphere, for example, their brains expect their bodies to experience a downward tug from gravity—conditions that don’t exist in space. As a result, roughly 60% to 80% of space travelers have experienced what scientists call “space motion sickness,” which can last for a few days or even longer. (91��Ƭ��n cosmonaut Gherman Titov holds the dubious honor of being the first human to vomit in space when he lost his lunch inside the Vostok 2 spacecraft).

In separate research, Clark and his colleagues are exploring whether space explorers can reduce space motion sickness through simple exercises, such as careful tilts of the head.

But icky feelings may also emerge when astronauts come back to Earth. NASA is planning to send humans to the moon this decade aboard the Orion or Dragon spacecrafts. When Orion, in particular, returns to Earth, it will likely plop into the ocean somewhere off the coast of California. There, astronauts may bob up and down in the waves for as long as an hour while they wait for rescue.

It's not a pretty picture, Lonner said: “If you look at Orion and Dragon, there are only a few porthole windows that really aren’t sufficient for giving astronauts a fixed view of Earth.”

Walk in the forest

Back at CU Boulder, in a lab down the hall from the human centrifuge, Clark steps into a different machine.

The metal cube painted blue is about the size of a small bedroom. It previously resided at NASA’s Johnson Space Center in Houston and is so big that the team had to bring it into the building in pieces, then put it back together on site.

Once Clark secures himself to a chair inside and shuts the door, the massive device rumbles to life and begins to move, sliding along a track on the floor. It swishes in a straight line from one end of the room to the other for several minutes.

“You feel like you’re getting rocked back and forth,” Clark says.

In fact, it feels like being rocked back and forth by waves—the researchers programmed the sled’s motion by drawing on data from real buoys in the Pacific Ocean.

In one recent experiment, the team took a two-stage approach to simulating the motion sickness that comes from water landings: First, the group spun 30 human subjects for an hour in the centrifuge. That spinning mimics the disorientation astronauts experience when they suddenly transition from microgravity to the harshness of Earth’s gravity.

Next, the researchers rocked the subjects in the sled for as much as an hour. If that sounds like a recipe for nausea, Lonner said, it was.

But, she added, the team also gave each of the subjects a pair of virtual reality goggles to wear. Half of the subjects saw an image of a fixed white dot against a black background. But the other subjects received a much richer picture—a digital forest complete with a few cartoon humans for scale. Those forests also moved in tandem with the sled. When it slid or tilted, so did the trees and people.

“It’s like a virtual window,” Lonner said.

It also did the trick. Lonner explained that if subjects experienced moderate symptoms of motion sickness for longer than two minutes, they exited the experiment. Only a third of the people wearing goggles showing just the white dot lasted for the entire hour in the sled. In contrast, nearly 80% of subjects watching the forest survived the ordeal.

A window opens

The researchers are working to build on their results, exploring, for example, whether adding more information to the forest scene can help reduce nausea even more. But they are optimistic that virtual reality could give astronauts returning to Earth a little relief.

Lonner sees the project as a way of opening space exploration up to more people—including people like her who get nauseous on airplanes. She’s even used some of the lessons from her research in her own life.

“I realized that it’s worse when the window is closed, and I can’t see the clouds passing by,” Lonner said. “Now, I’ll always open the window to watch the clouds.”

Researchers at CU Boulder advancing more trustworthy autonomous systems with U.S Air Force

Jeff Zehnder

Allie Anderson and Torin Clark at CU Boulder are conducting research into how humans and artificial intelligence systems work together.

The pair are part of a multi-university research team commissioned by the Air Force Office of Scientific Research to study trust in autonomous systems. It is an important and complex problem.

“Trust is a dynamic human state with multiple dimensions - it’s different for each individual and the specific system you’re using. Trusting a self-driving car if you want to go to sleep in the backseat is different than trusting Alexa to tell you the weather,” said Anderson, an assistant professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at the University of Colorado Boulder.

The work has broad applications across the technological spectrum, but the Air Force is particularly interested due to increasing integration of autonomy in military systems and the uncertainties faced by soldiers using them, said Anderson.

“There are many applications where autonomous systems may be used and – particularly with space-based applications – the human isn’t onsite with a satellite to have additional context, and you can’t always get all the data in real-time. We need to understand how users trust and view that type interaction with autonomy across a variety of situations,” Anderson said.

The initiative aims to build metrics and models for real time predictions of trust, with the goal of helping developers create better AI systems in the future, said Clark, an associate professor in Smead Aerospace.

“Space and military autonomy represent critically challenging environments and being able to estimate and predict human-operator trust will enable systems to intelligently alter their behaviors to complement their human teammates,” Clark said.

During the research, test subjects will be fitted with wearable sensors while they conduct tasks with AI systems. The sensors will collect physiological data on the body’s responses – things like heart rate and respiration – as well as how users physically interact with the systems. That includes where they are looking on a computer screen, the buttons they click, and how long they take to do an activity requested by the AI powered system.

“It’s exciting to work in this emerging field where there are important questions that need to be answered to move out of the laboratory and into operations,” Anderson said.

The three-year, $900,000 grant is being led overall by the University of California, Davis. CU Boulder’s work represents nearly $500,000 of the total award.

Heart experiments to help astronauts live better in space

Heart experiments to help astronauts live better in space Anonymous (not verified) Wed, 04/05/2023 - 10:29

An astronaut working with one of the experiments aboard the International Space Station.

Astronauts aboard the International Space Station are hard at work on research guided by students and researchers from the University of Colorado Boulder.

Two cardiovascular tissue experiments were launched to the ISS aboard SpaceX CRS-27 on March 15, 2023 and CU Boulder’s BioServe Space Technologies developed the hardware for both. The research stems from National Institutes of Health grants led by Stanford University and Johns Hopkins University.

“When astronauts go to space it can have negative impact on their cardiovascular systems,” said Stefanie Countryman, director of BioServe. “Our organs evolved to work here on Earth so they function differently in space. The goal with both of these projects is to better understand how these treatments impact cardiovascular issues in Earth bound people and to advance treatments that could be provided to astronauts before launch or while in space.”

BioServe has been designing, building, and flying microgravity life science research experiments and hardware since 1987. Government space agencies, universities, and private companies like SpaceX frequently contract with BioServe to take advantage of the center’s longstanding experience in space research.

The two experiments launched on March 15 include specialized hardware developed by BioServe specifically for these projects and will also utilize BioServe’s Space Automated Bioproduct Lab, an orbiting incubator that has been in use on ISS since 2015.

One of the experiments and its enclosure before launch here on Earth.

Past heart studies have shown that just four weeks of microgravity exposure causes significant changes in cell function and gene expression that could lead to long-term damage or cardiac muscle atrophy.

The Stanford experiment utilizes simplified heart tissues to test pharmaceuticals that could reduce microgravity-induced changes in heart cell function. Meanwhile the Johns Hopkins project aims to study human cardiomyocyte functional performance and the potential of specific therapeutics to prevent negative impacts.

While both projects are intended to help astronauts in space, the research could eventually also improve life for people here on Earth suffering from heart conditions due to aging or abnormalities that lead to a weakening of the heart muscle.

“Being able to design the hardware to support research like this for cell cultures and tissue engineering is very specialized,” Countryman said.

In addition to the hardware development, BioServe also conducts live uplinks with astronauts to walk them through the experiments. As both a research facility and educational center, BioServe employs full time staff and students to advance their work.

“Undergrad and grad students are responsible for assembly of hardware and kit design and helping during uplinks with the crew. Students are an integral part of operations,” Countryman said.

The one downside to working with astronauts is frequent late nights. ISS astronauts live and work on Coordinated Universal Time, so the crew day begins at 1:30 a.m. Colorado time. That means uplinks frequently occur long after most Americans have gone to sleep.

“It’s a small price to pay to work with people in space,” Countryman said.

Allie Anderson

Allie Anderson is probing trust in human-robot interactions with a major grant provided to promising early career faculty.

Anderson, an assistant professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at the University of Colorado Boulder, has earned a 2023 National Science Foundation CAREER Award. The prestigious program supports early career faculty with potential to become leaders in research and education.

The five-year grant will allow Anderson to investigate an area of increasing importance for society – how humans work over time with autonomous systems – with a specific focus on trust.

“Autonomous systems are increasingly integrated into our lives every day,” Anderson said. “When people over trust technology, they rely on it too much. If people under trust it, they don’t use a system at all or use it inappropriately. Trust also changes over time as you use a system.”

That evolution as someone interacts with an autonomous system on an ongoing basis is a particular emphasis. While there have been studies looking at how people use autonomous systems, they typically involve test subjects in a laboratory environment at a single point in time. Anderson is instead probing these interactions over a longer period and in something closer to a real-world environment.

The study will explore two different industries that already use autonomous systems: package distribution centers and general aviation.

To complete the research, Anderson has partnered with Amazon to conduct interviews and simulations with employees at the company’s distribution centers where package procurement is done with human-robot teams. The aviation component will focus on small plane pilots using upgraded avionics systems to provide guidance and navigation during flight.

“These autonomous systems are already in place, but like everything, they’re imperfect, so people have to decide how to trust them,” Anderson said.

Study participants will be fitted with a series of wearable sensors to collect a wide array of physiological data, including heart rate, respiration, skin conductance, even pupil diameter and blink count.

“The idea is people don’t have to report their response manually. The sensors get the signal from the body and estimate trust so we can know their trust level – how they’re feeling,” she said.

Wearable sensor technology, especially in aerospace applications, has long been a focus of Anderson’s work. She has conducted numerous investigations into human health and performance with an aim to developing technologies to measure and improve the body’s adaptations to extreme stressors, like those experienced in space.

This new research has could help manufacturers develop better autonomous systems in the future.

In addition to the research, the CAREER award also includes an education and outreach component. Anderson will be creating hands-on academic modules for rural Colorado high school math and biology classes.

“Students on the Front Range have a ton of resources, but there’s less on the Eastern Plains and in the mountain regions and I want to help with that,” she said. “These modules will be aligned with state curriculum standards and will focus on how we use math and probabilities, how we use physiological signals and trust.”

It is a particular passion for Anderson, who completed her master’s thesis on rural STEM education.

“I grew up on a farm in Southwest Missouri. We always looked at the stars as a family and it spurred my love of space. In third grade, my teacher did a lesson on astronauts and I was obsessed. I still am,” Anderson said.

The full title of Anderson’s CAREER award is Physiological Modeling of Longitudinal Human Trust in Autonomy for Operational Environments. The research will formally begin in August and run through summer 2028.

The Ann and H.J. Smead Department of Aerospace Engineering Sciences at the University of Colorado Boulder had another big year for research funding, bringing in nearly $48 million in awards.

The fiscal year 2022 number totals $47,834,766. It is the second highest year ever for funding in the department, behind only FY 2021, which topped $53 million.

“We have excellent faculty in our department who are being recognized for their expertise and it shows,” said Hanspeter Schaub, aerospace professor and department chair. “Space is a topic of interest again and the Air Force and Space Force are beginning to invest heavily into related research. Bioastronautics is also growing, with more access for humans to visit and work in space. Finally, remote sensing of and from space has been a strongly funded research area and fits out department expertise well.”

Over the last five years, the department’s research revenue has more than tripled, with significant growth in traditional aeronautics and aerospace fields and a push into newer areas like hypersonics.

The largest single grant during the most recent fiscal year was $15 million for the establishment of a new NASA hypersonics research center. The department also saw grants of over $1 million each in radio frequency research, orbital medicine, space domain awareness, virtual reality for space mission training, and artificial intelligence for drones.

Schaub expects the strong research funding totals to continue into the future.

“This is not a bubble in funding. There are several developments in progress that should keep this momentum going and it appears that this roughly $50 million a year funding level is here to stay,” Schaub said.
