Astronaut's Energy Requirements for Long-Term Space Flight (Energy) - 11.25.14
ISS Science for Everyone
Science Objectives for Everyone
Energy investigation measures an Astronaut's Energy Requirements for Long-Term Space Flight, a crucial factor needed for sending the correct amount of the right types of food with space crews. Nine astronauts will be examined during exercise and rest cycles three months before launch, three months after arriving at space station and adapting to the space environment, and after return to Earth. Physicians will measure metabolic rates, urine content, and bone density to determine energy needs.

Previous ISS Missions
- With the construction of the International Space Station and the related planned long-term human missions beyond low Earth orbit, the interest in nutrition as a countermeasure to the effects of space flight has increased dramatically. A growing body of data suggests a direct relationship between nutrition and the effects of space.
- The maintenance of energy balance appears critical but difficult during space flight. Clearly the determination of energy requirements is necessary for recommending healthy nutrition in weightlessness.
- Astronaut's Energy Requirements for Long-Term Space Flight (Energy) measures changes in energy balance after long term spaceflight, adaptations in the components of the total energy expenditure and derive an equation for the energy requirements of astronauts.
Astronaut's Energy Requirements for Long-Term Space Flight (Energy) determines the crewmembers energy requirements for long-term space flight. There is no compensation for severe negative energy balance during space flight.. This energy deficit affects all physiological functions. Energy measures changes in energy balance after long-term space flight, adaptations in the components of the total energy expenditure, and help to derive an equation for the energy requirements of crewmembers.
Astronauts often lose body mass with extended stays in space for reasons that remain unclear, although increased exercise as a microgravity countermeasure may be a factor. Knowing details of astronaut metabolism and activity, combined with other conditions, will help ensure that crews are properly nourished on long missions.
Extended bed rest due to age or illness has some parallels to a proper energy balance. Improved understanding from space missions will help in assessing patient needs on Earth.
