Description

a)    Initial State

Preventative (e.g., lighting, schedules) countermeasures and treatment countermeasures (e.g., medications) are being implemented operationally. Sleep loss and circadian misalignment, however, continue on orbit. Research continues to define ways through which these countermeasures can be more effectively used. This gap seeks to capture the need to integrate these countermeasures and equip crewmembers and medical operations with how to implement them individually.
Tools in Sleep Gap 8 will serve to not only inform scheduling decisions for critical ops, but these tools can also serve as the backbone for implementing countermeasures for each individual.

b)    Target for Closure

Countermeasures that have been validated and defined for individualized use, integrated into Sleep 8 tools, provided with guidelines and education materials for crewmembers and medical operations.

c)    Metrics for Interim Progress

(1) Determine individual factors needed to enhance Sleep Gap 8 models as mechanism through which an individualized countermeasure regimen is recommended (10%);
(2) Assess other countermeasures that may be needed, such as nutritional guidelines, stress management, and exercise recommendations (10%);
(3) Inform the development and enhancement of models in Sleep Gap 8 with (1) and results from investigations in this and other Sleep gaps (40%);
(4) Develop guidelines and update requirements regarding how tools can be used in mission   operations (30%);
(5) Update models based on new evidence (10%).

d)    Approach

Models of performance can also provide the structure through which countermeasures can be implemented operationally. As identified in Sleep Gaps 4, 5, and 6, results from studies will be used to inform scheduling tools. BHP research will work with operations to ensure that software is useful operationally.
