The investigators will conduct a series of ground-based analog missions that simulate work and living conditions during LDEMs such as, confinement for a long periods, social isolation, communication delay with MC, mission objectives, and off-nominal events. These conditions will examine and model the impact of crew autonomy implementations on both the crew and the MTS of crew and MC, and to determine whether its impact changes over time. The modeling effort will also examine the role of various team processes (e.g. communication, group dynamic) and states (e.g. team cohesion and efficacy) that the team literature has identified as critical backgrounds to team effectiveness but that have not been systematically addressed in team autonomy studies.
Investigators will use relevant research data available through NASA’s Life Sciences Data Archive (LSDA) not only to supplement the data they will collect from the simulations, but also at the onset of the project to develop models of the crew autonomy. In addition, they will use the data collected in space analogs and from the International Space Station (ISS) to develop models of the individual- and team-level relationships between crew autonomy, emergent states, and team performance. These models will be refined and validated using data from the simulations, and an additional model of the autonomy–performance relationship at the MTS level will be derived. Based on the LSDA data analyses and the analog simulations, investigators will identify leverage points for interventions in LDEMs and provide recommendations for countermeasures to mitigate threats to effective MTS functioning in long-duration missions.
This study has the following specific aims:
Each space crewmember will experience one of two autonomy implementations. This design will enable investigators to examine how different control structures impact team functioning and performance both within component teams and across space and ground teams. Implementations are defined in terms of autonomy level and timing/duration of the mission. Levels of crew autonomy - No Autonomy (MC Control), and High Autonomy - will be defined in terms of who is in charge of task scheduling and management, leadership and decision making, and information sharing.
Two unanticipated events will occur for the space crew during each flight segment, for a total of twelve events. These events will be scripted in collaboration with subject matter experts and will present unexpected challenges in terms of communication, problem solving, and decision making. Importantly, these events will also provide information concerning crew response to unexpected loss of autonomy. Half of the events will stretch the limits of the space crew’s expertise (Stretch events); that is, there will be medical or systems emergencies that the crew could possibly figure out themselves, but that would be more easily and reliably resolved by contacting experts within the MTS (i.e., in MC). The other events will be task or timing disruptions that are imposed by MC (Demand events) and must be accomplished as required (for example, an immediate systems verification or medical test, or a change in tasks or schedules). Embedding repeated events will allow investigators to examine whether different implementations of crew autonomy are associated with different entrainment processes across time, facilitating or impeding contact and collaboration with MC.
This experiment is in progress. Results aren't available at this time.
