Aims:

1. Provide personnel a 60-minute education session on sleep and sleep disorders, circadian rhythms and fatigue, including advice about sleep strategies and countermeasures that can be used to combat fatigue while on duty and increase sleep quality/quantity while off-duty, and countermeasures to facilitate circadian entrainment to the Mars sol. We will provide supportive educational materials (e.g., handouts, webbased resources) regarding those strategies and will seek to set up a website to support ongoing education throughout the mission.

 

2. Determine feasibility and acceptability of countermeasures used to facilitate circadian misalignment and to improve alertness via participants completing questionnaires.

 

 

3. Test hypothesis that there will be greater sleep disruption (less sleep duration as estimated by actigraphy) and greater dissatisfaction with sleep quality (subjective analysis via daily questionnaire) when scheduled to work on the Mars sol as compared to baseline data collected while working on a traditional earth (24 hr day) schedule.

 

4. Test the hypothesis that working on a Mars sol schedule will result in circadian misalignment (as assessed by analysis of melatonin secretion [6-sulfatoxymelatonin in urine]).

 

5. Test the hypothesis that decrements in performance (PVT and ANAM testing), increased on-the-job errors, and increased adverse safety outcomes (e.g., accidents and injuries) will be associated with sleep disruption and circadian misalignment.
