NASA/Don Pettit NASA astronaut Don Pettit fills a sphere of water with food coloring in this image from Oct. 20, 2024. Pettit calls experiments like these “science of opportunity” – moments of scientific exploration that spontaneously come to mind because of the unique experience of being on the International Space Station. During his previous missions, Pettit has contributed to advancements for human space exploration aboard the International Space Station resulting in several published scientific papers and breakthroughs.

Credit: NASA/Joel Kowsky NASA’s SpaceX Crew-8 mission successfully splashed down at 3:29 a.m. EDT Friday, off Pensacola, Florida, concluding a nearly eight-month science mission and the agency’s eighth commercial crew rotation mission to the International Space Station.
After launching March 3 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida, NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin, spent 232 days aboard the space station.
Recovery teams from NASA and SpaceX quickly secured the spacecraft and assisted the astronauts during exit. The crew now will head to NASA’s Johnson Space Center in Houston, while the Dragon spacecraft will return to SpaceX facilities at Cape Canaveral Space Force Station in Florida for inspection and refurbishment for future missions.
During their mission, crew members traveled nearly 100 million miles and completed 3,760 orbits around Earth. They conducted new scientific research to advance human exploration beyond low Earth orbit and benefit human life on Earth. Research and technology demonstrations included conducting stem cell research to develop organoid models for studying degenerative diseases, exploring how fuel temperature affects material flammability, and studying how spaceflight affects immune function in astronauts. Their work aims to improve astronaut health during long-duration spaceflights, contributing to critical advancements in space medicine and benefitting humanity.
Crew-8’s return follows the arrival of NASA’s SpaceX Crew-9 to the orbiting laboratory Sept. 29. These missions are part of NASA’s Commercial Crew Program, which provides reliable access to space, maximizing the use of the station for research and development and supporting future missions beyond low Earth orbit by partnering with private companies to transport astronauts to and from the space station.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Expedition 64 Flight Engineer Victor Glover of NASA sips on a water bag. The latest book marks our third effort to review available literature regarding the role of nutrition in astronaut health. In 2009, we reviewed the existing knowledge and history of human nutrition for spaceflight, with a key goal of identifying additional data that would be required before NASA could confidently reduce the risk of an inadequate food system or inadequate nutrition to as low as possible in support of human expeditions to the Moon or Mars. We used a nutrient-by-nutrient approach to address this effort, and we included a brief description of the space food systems during historical space programs.
In 2014, we published a second volume of the book, which was not so much a second edition, but rather a view of space nutrition from a different perspective. This volume updated research that had been published in the intervening 6 years and addressed space nutrition with a more physiological systems-based approach.
The current version is an expanded, updated version of that second book, providing both a systems approach overall, but also including details of nutrients and their roles within each system. As such, this book is divided into chapters based on physiological systems (e.g., bone, muscle, ocular); highlighted in each chapter are the nutrients associated with that particular system. We provide updated information on space food
systems and constraints of the same, and provide dietary intake data from International Space Station (ISS) astronauts.
We present data from ground-based analog studies, designed to mimic one or more conditions similar to those produced by spaceflight. Head-down tilt bed rest is a common analog of the general (and specifically musculoskeletal) disuse of spaceflight. Nutrition research from Antarctica relies on the associated confinement
and isolation, in addition to the lack of sunlight exposure during the winter months. Undersea habitats help expand our understanding of nutritional changes in a confined space with a hyperbaric atmosphere. We also review spaceflight research, including data from now “historical” flights on the Space Shuttle, data from the Russian space station Mir, and earlier space programs such as Apollo and Skylab. The ISS, now more than
20 years old, has provided (and continues to provide) a wealth of nutrition findings from extended-duration spaceflights of 4 to 12 months. We review findings from this platform as well, providing a comprehensive review of what is known regarding the role of human nutrition in keeping astronauts healthy.
With this latest book, we hope we have accurately captured the current state of the field of space food and nutrition, and that we have provided some guideposts for work that remains to be done to enable safe and successful human exploration beyond low-Earth orbit.
