NASA/Kim Shiflett NASA astronauts Christina Koch, Artemis II mission specialist, and Victor Glover, Artemis II pilot, walk on the crew access arm of the mobile launcher in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Tuesday, Aug. 12, 2025.
On Aug. 11 and 12, teams with the agency’s Exploration Ground Systems Program along with NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, practiced launch day operations if launch occurs at night. They simulated putting their spacesuits on and driving to the launch pad as well as emergency procedures they would use in the unlikely event of an emergency during the launch countdown requiring them to evacuate the launch pad.
Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars.

While it may sound like the opening to a punchline, this scientific question was at the heart of a research experiment that orbited the Moon aboard Artemis I.NASA astronaut and Expedition 65 Flight Engineer Mark Vande Hei caring for chili peppers aboard the International Space Station. NASA New research uncovers the connection between space agriculture and astronaut health. A study published in npj Microgravity shows how analyzing diverse datasets together can reveal insights that might otherwise be missed — in this case, linking space-grown food quality to astronaut nutrition and gut health.
The paper reviewed previous studies of plants grown aboard the International Space Station. The authors found that some edible plants grown in low Earth orbit have lower concentrations of essential nutrients, like calcium and magnesium, than those grown on Earth.
The reduced levels of these nutrients could make crops not as effective in mitigating the bone loss and reduced immune function that astronauts encounter in space.
Working Groups Uncover Hidden Health Connections
Three Analysis Working Groups from NASA’s Open Science Data Repository collaborated to make this paper possible. These discipline-specific groups typically work independently, but this project sparked conversations among researchers with different specialties.
Researchers combined plant data, crop nutrition profiles, gut studies, and astronaut blood biomarkers — a data integration effort of the Biological and Physical Sciences Division open science model. The work also draws on data from JAXA (Japan Aerospace Exploration Agency).
For NASA, these findings offer new insights into how to feed and support astronauts in space, particularly on long-duration missions to the Moon and Mars.
Seeks Ways to Improve Space Diets
The study also examined increased intestinal permeability — often called “leaky gut” — a condition that can result from poor nutrition and may be exacerbated by the space environment. Intestinal permeability may interfere with how astronauts absorb nutrients and regulate immune responses.
If properly engineered, space-grown crops could offer a solution to these health challenges. The team outlined several potential strategies, including bioengineering plants with higher nutrient content, incorporating more antioxidant-rich species, and designing personalized nutrition plans using astronauts’ genetic information.
The study suggests targeting specific biological pathways, such as using compounds like quercetin, an antioxidant found in certain crops, to address bone health challenges at the molecular level. The approach emphasizes designing nutrition plans based on individual astronaut physiology, including how well their digestive systems can absorb nutrients.

NASA astronauts Anne McClain and Nichole Ayers, and JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi will answer questions about their mission. The crew returned to Earth on Aug. 9.
Live coverage of the news conference will stream on the agency’s YouTube channel. Learn how to watch NASA content through a variety of additional platforms, including social media.
This event is open to media to attend in person or virtually. For in-person, media must contact the NASA Johnson newsroom no later than 12 p.m., Tuesday, Aug. 19, at: jsccommu@mail.nasa.gov or 281-483-5111. Media participating by phone must dial into the news conference no later than 10 minutes prior to the start of the event to ask questions. Questions also may be submitted on social media using #AskNASA. A copy of NASA’s media accreditation policy is available on the agency’s website.
The crew spent 146 days aboard the orbiting laboratory, traveling nearly 62,795,205 million miles and completing 2,368 orbits around Earth. While living and working aboard the station, the crew completed hundreds of science experiments and technology demonstrations. The latest NASA space station news, images, and features are available on Instagram, Facebook, and X.
NASA’s Commercial Crew Program has delivered on its goal of safe, reliable, and cost-effective transportation to and from the International Space Station from the United States through a partnership with American private industry. This partnership is opening access to low Earth orbit and the International Space Station to more people, more science, and more commercial opportunities. For almost 25 years, people have continuously lived and worked aboard the space station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration of the Moon as we prepare for Mars.

Credit: NASA NASA has selected KBR Wyle Services, LLC of Fulton, Maryland, to provide services to the Human Health and Performance Directorate at the agency’s Johnson Space Center in Houston, which focuses on astronaut health, occupational health, and research that could help mitigate health risks for future human spaceflight missions.
The Human Health and Performance Contract 2 is a follow-on single-award indefinite-delivery/indefinite-quantity contract that begins its five-year period of performance on Nov. 1, with two possible option periods that could extend it through 2035. The total estimated value of the base period plus the optional periods is $3.6 billion. Leidos, Inc. of Reston, Virginia, is a subcontractor.
The contract will acquire support services for several programs, primarily at NASA Johnson. This includes the Human Research Program, International Space Station Program, Commercial Crew Program, Artemis campaign, and more. Services include ensuring crew health, safety, and performance; providing occupational health services; and conducting research into mitigating risks to the health, safety, and performance of future spaceflight crews.
The Human Health and Performance Directorate leads the global spaceflight community in protecting astronaut health and enabling human mission performance. Its vision focuses on humans living, working, and thriving in space, on the Moon and on to Mars, and its mission is to lead the global spaceflight community in protecting astronaut health and enabling human mission performance.
