Adventurous alum serves as test subject for 30-day NASA isolation project
by Staff Writers
Boulder CO (SPX) Dec 13, 2016

Ulyana Horodyskyj.

With research expeditions to Antarctica, Greenland, Iceland and Mount Everest already under her belt, alumni Ulyana Horodyskyj was no stranger to harsh and isolated environments. But for a moment on Sept. 19, she wondered if she'd met her match.

That day, Horodyskyj climbed inside a windowless 636-square-foot pod housed in a warehouse at NASA's Johnson Space Center, switched off her phone, high-fived the three strangers she'd be spending the next 30 days inside with, and watched the doors shut tight.

"They basically locked us in and said, 'Have at it. Get to work,'" recalls Horodyskyj, 30, a Boulder-based scientist and entrepreneur who earned her PhD in geosciences at CU Boulder in 2015. "It felt surreal."

This fall, Horodyskyj served as commander of the Mission XII crew of NASA's Human Exploration Research Analog (HERA) project, a multi-year endeavor to study just what happens to people's bodies, brains and psyches when they're isolated inside a confined space for long durations with other adults.

The project aims to simulate what it might be like for astronauts traveling to and from Mars or an asteroid - journeys that could take years. NASA has so far selected 48 healthy volunteer test-subjects endowed with "astronaut-like" qualities (physical fitness, emotional resilience, teamwork and leadership skills) for mock missions in which they were videoed and monitored round-the-clock. Campaign 3 was a confined isolation study focused on psychological, health and cognitive impacts, and using blood and saliva tests, surveys and other measures to assess response to stress.

Horodyskyj, who has conducted research at 22,000 feet and once spent three frigid weeks hunkered down in a tent with two other scientists on Canada's Baffin Island, seemed an ideal fit.

"She brings unique life-skills with her that we thought would be applicable to this project," says Patrice Yarbough, PhD, principal investigator for HERA Campaign 3.

Life in the pod
For her 30-day mission (a simulation of a 715-day journey to the asteroid Geographos) Horodyskyj worked, ate, slept, and exercised all in a two-story structure about a quarter the size of the "HAB" in the movie, "The Martian."

She spent 16-hour days working much like an astronaut would - studying hydroponic plants, practicing flight maneuvers via virtual reality, and staging mock landings and takeoffs. She was banned from all email or social media and had no contact with the outside world, aside from regular briefings with their mock "mission control" and the rare pre-scheduled call home. On occasion, the real world would make its presence known.

"I remember hearing a thunderstorm outside one night," she recalls. "I called mission control and said, 'Hey. Are we passing through a debris field?' I tried to stay in character."

Ten days in, she was summoned to the airlock by mission control, where they delivered some real-world news: Out of 18,300 applicants she was one of 120 being considered for NASA's Astronaut Candidate program to train people for future spaceflight. "I was so elated but I couldn't share it with my family. That was tough."

At another point, the team was kept awake for 39 hours for a sleep deprivation study. That too was a low point. She also missed blue skies, mountain air, running and - she admits - Facebook.

"In some ways it was really cleansing to be without it, particularly during election season. But in other ways it was really hard."

Exploring new horizons
After earning degrees from Rice and Brown universities, Horodyskyj came to CU in 2011, drawn by a fellowship with the Cooperative Institute for Research in Environmental Sciences (CIRES) and the chance to have famed Himalayan earthquake researcher Professor Emeritus Roger Bilham as her PhD advisor.

For her glacial lakes research, she made multiple trips to Nepal, taking samples on Mount Everest and launching the Sherpa-Scientist Initiative, a citizen-science initiative, aimed at teaching Sherpas how to do field science. (The program is expected to be featured in the "Crowd and the Cloud" series on PBS in Spring, 2017).

She has worked on all seven continents. But her time inside HERA broadened her perspective even further, she says.

"It showed me you can put together a team of people who don't know each other at all in a really tough situation and still be very successful as long as you have open communication."

She's now waiting to hear back about the Astronaut program. And she has launched her own company, Science in the Wild, LLC, which takes ordinary citizens on science expeditions in uncharted places.

"There has always been something within me that wants to explore the next horizon. I can't wait to see what's next."

Early US astronauts faced uncertainty, danger and death
Miami (AFP) Dec 9, 2016
John Glenn became the first American to orbit the Earth in 1962, but for a solid hour of that journey, NASA feared he was about to die in a blazing fireball. In fact, all of the original crew of astronauts, known as the Mercury 7, risked life and limb in order to explore the frontier of space, and some died in the effort. The death Thursday at 95 of Glenn, the last of the so-called Origi ... read more
