Expedition 71 Flight Engineer and NASA astronaut Jeanette Epps poses for a portrait inside the seven-window cupola, the International Space Station’s “window to the world,” while orbiting 259 miles above Greece.NASA NASA astronaut Jeanette Epps retired May 30, after nearly 16 years of service with the agency. Epps most recently served as a mission specialist during NASA’s SpaceX Crew-8 mission, spending 235 days in space, including 232 days aboard the International Space Station, working on hundreds of scientific experiments during Expedition 71/72.
“I have had the distinct pleasure of following Jeanette’s journey here at NASA from the very beginning,” said Steve Koerner, acting director of NASA’s Johnson Space Center in Houston. “Jeanette’s tenacity and dedication to mission excellence is admirable. Her contributions to the advancement of human space exploration will continue to benefit humanity and inspire the next generation of explorers for several years to come.”
Epps was selected in 2009 as a member of NASA’s 20th astronaut class. In addition to her spaceflight, she served as a lead capsule communicator, or capcom, in NASA’s Mission Control Center and as a crew support astronaut for two space station expeditions.
“Ever since Jeanette joined the astronaut corps, she has met every challenge with resilience and determination,” said Joe Acaba, NASA’s chief astronaut. “We will miss her greatly, but I know she’s going to continue to do great things.”
Epps also participated in NEEMO (NASA Extreme Environment Mission Operation) off the coast of Florida, conducted geologic studies in Hawaii, and served as a representative to the Generic Joint Operations Panel, which addressed crew efficiency aboard the space station.
The Syracuse, New York, native holds a bachelor’s degree in physics from Le Moyne College in Syracuse. She also earned master’s and doctorate degrees in aerospace engineering from the University of Maryland in College Park. During her graduate studies, she became a NASA Fellow, authoring several journal and conference articles about her research. Epps also received a provisional patent and a U.S. patent prior to her role at NASA.

NASA and ISRO (Indian Space Research Organisation) are collaborating to launch scientific investigations aboard Axiom Mission 4, the fourth private astronaut mission to the International Space Station. These studies include examining muscle regeneration, growth of sprouts and edible microalgae, survival of tiny aquatic organisms, and human interaction with electronic displays in microgravity.
The mission is targeted to launch no earlier than Tuesday, June 10, aboard a SpaceX Dragon spacecraft on the company’s Falcon 9 rocket from NASA’s Kennedy Space Center in Florida
Regenerating muscle tissue
Immunofluorescent image of human muscle fibers for Myogenesis-ISRO, showing nuclei (blue) and proteins (red).Institute for Stem Cell Science and Regenerative Medicine, India During long-duration spaceflights, astronauts lose muscle mass, and their muscle cells’ regenerative ability declines. Researchers suspect this may happen because microgravity interferes with metabolism in mitochondria, tiny structures within cells that produce energy. The Myogenesis-ISRO investigation uses muscle stem cell cultures to examine the muscle repair process and test chemicals known to support mitochondrial function. Results could lead to interventions that maintain muscle health during long-duration space missions, help people on Earth with age-related muscle loss and muscle-wasting diseases, and assist athletes and people recovering from surgery.
Sprouting seeds

Bioactive compounds in fenugreek seeds also have therapeutic properties, and the leaves contain essential vitamins and minerals. Learning more about how space affects the genetics, nutritional content, and other characteristics over multiple generations of plants could inform the development of ways for future missions to reliably produce plants as a food source.
Microalgae growth

Highly digestible microalgae species packed with nutrients could be a food source on future space missions. These organisms also grow quickly, produce energy and oxygen, and consume carbon dioxide, traits that could be employed in life support and fuel systems on spacecraft and in certain scenarios on Earth.
Tiny but tough
NASA astronaut Peggy Whitson sets up the BioServe microscope, which will be used by the Voyager Tardigrade-ISRO investigation.NASA Tardigrades are tiny aquatic organisms that can tolerate extreme conditions on Earth. Voyager Tardigrade-ISRO tests the survival of a strain of tardigrades in the harsh conditions of space, including cosmic radiation and ultra-low temperatures, which kill most life forms. Researchers plan to revive dormant tardigrades, count the number of eggs laid and hatched during the mission, and compare the gene expression patterns of populations in space and on the ground. Results could help identify what makes these organisms able to survive extreme conditions and support development of technology to protect astronauts on future missions and those in harsh environments on Earth.
Improving electronic interactions

Voyager Displays-ISRO examines how spaceflight affects use of such devices.NASA Research shows that humans interact with touchscreen devices differently in space. Voyager Displays – ISRO examines how spaceflight affects interactions with electronic displays such as pointing tasks, gaze fixation, and rapid eye movements along with how these interactions affect the user’s feelings of stress or wellbeing. Results could support improved design of control devices for spacecraft and habitats on future space missions as well as for aviation and other uses on Earth.

NASA Nearly all of NASA’s ninth class of astronaut candidates, along with two European trainees, poses for photos in the briefing room in the public affairs facility at NASA’s Johnson Space Center in Houston on July 7, 1980.
Group 9 was announced on May 29, 1980; the candidates would go on to make history in spaceflight and at NASA. For example, Charles Bolden (kneeling at far right) traveled to orbit four times aboard the space shuttle between 1986 and 1994, then became the agency’s first African American administrator in 2009. Franklin Chang-Diaz (fifth from the right, standing) was the first Hispanic American to fly in space and Jerry Ross (middle, standing in the back) was the first person to be launched into space seven times.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
How do we do research in zero gravity?
Actually when astronauts do experiments on the International Space Station, for instance, to environment on organisms, that environment is actually technically called microgravity. That is, things feel weightless, but we’re still under the influence of Earth’s gravity.
Now, the very microgravity that we’re trying to study up there can make experiments actually really kind of difficult for a bunch of different reasons.
First of all, stuff floats. So losing things in the ISS is a very real possibility. For example,
there was a set of tomatoes that was harvested in 2022 put it in a bag and it floated away and we couldn’t find it for eight months.
So to prevent this kind of thing from happening, we use a lot of different methods, such as using enclosed experiment spaces like glove boxes and glove bags. We use a lot of Velcro to stick stuff to.
Another issue is bubbles in liquids. So, on Earth, bubbles float up, in space they don’t float up, they’ll interfere with optical measurements or stop up your microfluidics. So space experiment equipment often includes contraptions for stopping or blocking or trapping bubbles.
A third issue is convection. So on Earth, gravity drives a process of gas mixing called convection and that helps circulate air. But without that in microgravity we worry about some of our experimental organisms and whether they’re going to get the fresh air that they need. So we might do things like adding a fan to their habitat, or if we can’t, we’ll take their habitat and put it somewhere where there might already be a fan on the ISS or in a corridor where we think they are going to be a lot of astronauts moving around and circulating the air.
Yet another issue is the fact that a lot of the laboratory instruments we use on Earth are not designed for microgravity. So to ensure that gravity doesn’t play a factor in how they work, we might do experiments on the ground where we turn them on their side or upside down, or rotate them on a rotisserie to make sure that they keep working.
So, as you can tell, for every experiment that we do on the International Space Station, there’s a whole team of scientists on the ground that has spent years developing the experiment design. And so I guess the answer to how we do research in microgravity is with a lot of practice and preparation.
