mechanisms,” then there will have to be a significant increase in funding for research activities on the ISS for the behavior and performance research program to answer this question.

Maximizing ISS Research Potential

As detailed above, the main factors limiting utilization of the ISS in the Behavior and Performance area are the absence of any significant research program for the ISS, which primarily reflects budgetary constraints, and the small crew size and limited crew time. The development of a research program on the ISS in the Behavior and Performance area will require stable and predictable funding for research. Since the crew size will be limited to three people for at least the next 6 years, information that is available on crew performance aboard the ISS from other sources should be used for scientific study. Information collected as part of the flight medicine program, for instance, on medication use, sleep-wake cycles, and cognitive assessments, could be used to provide further information on crew performance.
