How Do Astronauts Get in Shape? – New “Ask SME” from NASA eClips
The NASA Science Activation program’s NASA eClips project, led by the National Institute of Aerospace (NIA), aims to increase Science, Technology, Engineering, & Mathematics (STEM) literacy and inspire the next generation of engineers and scientists by providing effective web-based, standards-aligned, in-school and out-of-school learning and teaching resources through the lens of NASA.
As a part of this work, NASA eClips professionally produces the Ask SME: Close-up With a NASA Subject Matter Expert video series to capture a glimpse of NASA SME’s personal interests and career journeys. Each video can be used to spark student interest and broaden their ideas of who the Science, Technology, Engineering, and Mathematics (STEM) workforce might include (everyone!) and the kinds of work they do.
On September 19, 2024, NASA eClips released the most recent video in the Ask SME series, featuring Corey Twine from NASA’s Johnson Space Center. Twine is an Astronaut Strength and Conditioning Specialist who works with astronauts to keep them physically fit for work on Earth and while they are in space. He shares insights about how he helps the astronauts and what inspired him to pursue this career.

NASA astronaut Tracy C. Dyson works on a computer inside the International Space Station. Credit: NASA NASA astronaut Tracy C. Dyson will share details of her recent six-month mission aboard the International Space Station in a news conference at 11 a.m. EDT Friday, Oct. 4, at the agency’s Johnson Space Center in Houston.
The news conference will air live on NASA+ and the agency’s website. Learn how to stream NASA content through a variety of platforms, including social media.
Media interested in participating in person must contact the NASA Johnson newsroom no later than 5 p.m. Thursday, Oct. 3, at 281-483-5111 or jsccommu@mail.nasa.gov.
Media wishing to participate by phone must contact the newsroom no later than two hours before the start of the event. NASA’s media accreditation policy is available online. To ask questions by phone, media must dial into the news conference no later than 10 minutes prior to the start of the call. Questions may also be submitted on social media by using #AskNASA.
Spanning 184 days in space, Dyson’s third spaceflight covered 2,944 orbits of the Earth and a 78-million-mile journey as an Expedition 70/71 flight engineer. Dyson also conducted one spacewalk of 31 minutes, bringing her career total to 23 hours, 20 minutes on four spacewalks. Dyson returned to Earth on Sept. 23, as planned, along with her crewmates, Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub.
Dyson launched on March 23 and arrived at the station March 25 alongside Roscosmos cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus. Novitskiy and Vasilevskaya were aboard the station for 12 days before returning home with NASA astronaut Loral O’Hara on April 6.
While aboard the orbiting lab, Dyson conducted dozens of scientific and technology activities to benefit future exploration in space and life back on Earth. She remotely controlled a robot on Earth’s surface from a computer aboard the station and evaluated orbit-to-ground operations. She operated a 3D bioprinter to print cardiac tissue samples, which could advance technology for creating replacement organs and tissues for transplants on Earth.
Dyson also participated in the crystallization of model proteins to evaluate the performance of hardware that could be used for pharmaceutical production and ran a program that uses student-designed software to control the station’s free-flying robots, inspiring the next generation of innovators.

NASA’s SpaceX Crew-9 commander Nick Hague is pictured in his flight suit during training at SpaceX headquarters in Hawthorne, California. Hague will perform human health and performance research on the International Space Station as part of his mission.SpaceX NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will soon dock with the International Space Station as part of the agency’s SpaceX Crew-9 mission, a venture which will enhance scientific research and bolster the knowledge about how people can live and work in space.
During the planned five-month mission, Hague’s mission tasks will include participating in a variety of research projects for NASA’s Human Research Program. Each study is designed to help address the health challenges that astronauts may face during future long-duration missions to the Moon, Mars, and beyond.
“Hague’s experiences and research may potentially lead to scientific breakthroughs that may not be possible on Earth,” said Steven Platts, chief scientist for human research at NASA’s Johnson Space Center in Houston.
A major focus for Hague’s time aboard the station is to study the suite of space-related vision disorders called Spaceflight Associated Neuro-ocular Syndrome (SANS) which occur as body fluids shift toward the head in weightlessness. These shifts can cause changes to the eye: the optic nerve can swell, the retina may develop folds, and the back of the eye can even flatten. Earlier research suggests multiple factors contribute to the syndrome, so two vision-related studies on this mission will tackle different yet distinct approaches that may help address or even prevent such changes during future missions.
One project, called Thigh Cuff, will explore whether wearing fitted cuffs could counter the syndrome by keeping more bodily fluids in the legs. Thigh cuffs are compact, lightweight, and easy to use, which makes them appealing for potential use during long-duration, deep space missions.
For this study, Hague will wear the thigh cuffs for six hours during two sessions. To help researchers measure how well the cuffs work, he will record ultrasound images of blood flow in his legs and neck veins during the sessions. Researchers will also compare this data against ultrasounds taken without the cuff to examine flow differences.
“Thigh cuffs like these may allow researchers to better investigate medical conditions that result in extra fluid in the brain or too much blood returning to the heart,” said study leader Brandon Macias at NASA Johnson.
In another study, Hague will test if a vitamin regimen may help combat SANS. The study, led by Sara Zwart, a nutritional biochemist at NASA Johnson, seeks to examine if a daily vitamin B supplement—taken before, during, and after flight—can prevent or mitigate swelling at the back of the eye. The research will also assess how an individual’s genetics may influence the response.
“Earlier research suggests that some people are more susceptible to this ocular syndrome than others based on genetics that can influence B vitamin requirements, so taking daily vitamins may make all the difference,” Zwart said. “We think by giving the B vitamins, we could be taking that piece of genetic variability out of the equation.”
The work also may eventually improve care options for women on Earth with polycystic ovary syndrome, a condition that can cause eye changes and infertility in women. Researchers hope that patients may similarly benefit from targeting the same genetic pathways and vitamin supplementation as crew members in space.
Hague also will record data to study whether a new way of administering a common anti-nausea medicine can help alleviate motion sickness following launch and landing. In this study, Hague can self-administer a novel nasal gel formulation of the medication scopolamine. Hague will note his experiences using this medicine and any other motion sickness aides, including alternative medications or behavioral interventions like specific head movements.
This research, led by neuroscientist Scott Wood of NASA Johnson, eventually will include 48 people.
“Our goal is to understand how to help future space travelers adapt to motion sickness when living and working in space,” Wood said. “Crew members must stay healthy and perform key tasks, including landing on the Moon and other destinations.”
To help NASA plan future missions, Hague also will participate in human research studies that tackle other space challenges, such as avoiding injury upon landing back on Earth and learning how space travel affects the human body on a molecular level.

NASA/Jim Grossmann In this photo from Aug. 7, 2009, Jose Hernandez, mission specialist, smiles at the camera as he waits for his turn to enter the space shuttle Discovery as part of STS-128. It was the 128th Shuttle mission and the 30th mission to the International Space Station. While at the orbital lab, the STS-128 crew conducted three spacewalks.
Hernandez joined NASA’s Johnson Space Center in Houston in 2001. There, he was a materials research engineer in the Materials & Processes branch; eventually, he became branch chief. In 2004, he was selected as an astronaut candidate, and in 2009, he became a crew member of STS-128.
