Human Adaptation to Spaceflight: The Role of Food and Nutrition

October 23, 2024 NeRD

3 min read 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…

Artemis I Radiation Measurements Validate Orion Safety for Astronauts

October 9, 2024 NeRD

On flight day 13, Orion reached its maximum distance from Earth during the Artemis I mission when it was 268,563 miles away from our home planet. Orion has now traveled farther than any other spacecraft built for humans. Credit: NASA NASA’s Orion spacecraft is designed to keep astronauts safe in deep space, protecting them from the unforgiving environment far from Earth. During the uncrewed Artemis I mission, researchers from NASA, along with several collaborators, flew payloads onboard Orion to measure potential radiation exposure to astronauts. Radiation measurements were taken inside…

Astronaut Exercise

May 20, 2024 NeRD

Science in Space: May 2024 Future missions to the Moon and Mars must address many challenges, including preventing loss of bone and muscle tissue in astronauts. Research on the International Space Station is helping to address this challenge. Without Earth’s gravity, both bone and muscle atrophy, or become smaller and weaker. Early on, scientists realized that exercise is a critical part of maintaining healthy bones and muscles in space, just as it is on Earth. From simple elastic bands on early missions, exercise hardware has become increasingly advanced. Current equipment…
