“…To further determine the effects of strawberry plants on the mood of people, we detected the level of cortisol, as an indicator of the activity of the endocrine system (Groemer et al, 2010;Roma et al, 2011;Collado et al, 2017). Previous studies had shown that a decrease in stress levels led to a decrease in cortisol levels (Park et al, 2007;Tsunetsugu et al, 2010;Beil and Hanes, 2013).…”

In manned deep-space exploration, extremely isolated environments may adversely affect the mood and cognition of astronauts. Horticultural plants and activities have been proven to be effective in improving their physical, psychological, and cognitive states. To assess the effects of applying horticultural plants and activities in isolated environments, this study investigated the influence of viewing strawberry plants on the mood of people in a laboratory experiment as indicated by heart rate, salivary cortisol, and psychological scales. The results showed that heart rate and salivary cortisol were significantly decreased after viewing strawberry plants for 15 min. "Tension" and "confusion" scored using the Profile of Mood States negative mood subscales, and anxiety levels measured using the State-Trait Anxiety Inventory scale were also significantly reduced. This study further explored the impact of viewing strawberry plants on cognition. A notable reduction of the subjects' reaction time after 15-min plant viewing was observed. Based on these findings, a long-duration isolated experiment in a bioregenerative life support system-"Lunar Palace I"-was conducted. A similar trend was obtained that crew members' mood states were improved by viewing the strawberry plants, but no significant change was observed. This study provided some experimental evidence for the benefits of interacting with strawberry plants in isolated environments.

“…Today, teams on Earth and in space work tightly together to plan, schedule, and successfully execute spaceflight operations. While there are some research investigations that have attempted to quantify the effect of crew autonomy [4][5][6], practical operational application of crew autonomy for spaceflight remains largely unexplored.…”

Through Playbook, a planning and scheduling software tool, we have incrementally enabled the capability for Earth analog mission crews to modify their schedules at various levels of complexity. Playbook allows the crew to create new activities from scratch, add activities or groups of activities from a Task List, and reschedule or reassign flexible activities. The crew is also able to identify if plan modifications create violations, i.e., plan constraints not being met. This paper summarizes our observations with qualitative evidence from four NASA Extreme Environment Mission Operations (NEEMO) analog missions that supported self-scheduling as a feasible operational concept.

“…Our previous research has centered around the design and usability of scheduling tools for self-scheduling in analog environments (Marquez et al, 2017, 2019) and in spaceflight (Marquez, Hillenius, Healy & Silva-Martinez, 2019). Others have explored the positive behavioral effects on crew with scheduling autonomy (Kanas, 2015; Roma et al, 2011). However, none of this research provides insight into the specific components of scheduling task complexity that exist in spaceflight operations and their effect on a scheduler’s performance.…”

Human Performance of Novice Schedulers for Complex Spaceflight Operations Timelines

Objective Investigate the effects of scheduling task complexity on human performance for novice schedulers creating spaceflight timelines. Background Future astronauts will be expected to self-schedule, yet will not be experts in creating timelines that meet the complex constraints inherent to spaceflight operations. Method Conducted a within-subjects experiment to evaluate scheduling task performance in terms of scheduling efficiency, effectiveness, workload, and situation awareness while manipulating scheduling task complexity according to the number of constraints and type of constraints. Results Each participant ( n = 15) completed a set of scheduling problems. Results showed main effects of the number of constraints and type of constraint on efficiency, effectiveness, and workload. Significant interactions were observed in situation awareness and workload for certain types of constraints. Results also suggest that a lower number of constraints may be manageable by novice schedulers when compared to scheduling activities without constraints. Conclusion Results suggest that novice schedulers' performance decreases with a high number of constraints, and future scheduling aids may need to target a specific type of constraint. Application Knowledge on the effect of scheduling task complexity will help design scheduling systems that will enable self-scheduling for future astronauts. It will also inform other domains that conduct complex scheduling, such as nursing and manufacturing.
