Experiment/Payload Overview

Brief Summary

Astronaut's Energy Requirements for Long-Term Space Flight (Energy) will measure changes in energy balance in crewmembers following long term space flight. Energy will also measure adaptations in the components of the total energy expenditure of astronauts to derive an equation for the energy requirements of astronauts.

    Experiment/Payload Description

    Research Summary

    • 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) will measure 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.

    Description

    Astronaut's Energy Requirements for Long-Term Space Flight (Energy) will help determine the crewmembers energy requirements for long-term space flight. Severe negative energy balance during space flight, for which during long-term space flight, there is no possible compensation. This energy deficit may affect all physiological functions. Energy will measure changes in energy balance after long term space flight, measure adaptations in the components of the total energy expenditure and derive an equation for the energy requirements of crewmembers.

    Operational Protocols

    Energy will utilize ISS meals (2 breakfast, 1 lunch & 1 dinner) for the inflight portion of the investigation. The European Space Agency urine collection system will also be utilized.

    Preflight there will be one session between at L-3 months with 1-day of measurements and urine collection. A body mass measurement and a Dual Energy X-ray Absorptiometry (DEXA) scan before launch. Inflight after L+3 months and more than 3 weeks before return a Pulmonary Function System (PFS) measurement, resting metabolic rate, diet induced thermogenesis, urine and water sampling will be performed.

    Postflight a DEXA scan and body mass measurement will be taken. A total of 9 subjects are needed to complete the Energy investigation.
