Description

Initial State:

Human Factors (HF) does not currently have a complete, quantitative risk definition [including established critical thresholds or ranges for various mission attributes (e.g., duration, resupply)] for incompatible vehicle/habitat design, nor is there a description of the relative contribution of the contributing factors and how the human accommodation in space vehicle/habitat design compares to the human accommodation in terrestrial vehicle/habitat design. HF is concerned with the physical aspects of this risk; whereas, BMed-Sleep and Team are concerned with the psychological aspects of this risk.

Interim Steps:

Establish a Habitability Working Group composed of representatives from relevant HRP Elements (e.g., ExMC, HHC), Habitability Subject Matter Experts, and stakeholders. The Habitability Working Group will provide a forum for activities such as assessing quality and maturity of solicitation products, assessing potential collaboration opportunities with other HRP Elements and/or external research groups, and vetting guidelines.

  • Review available data sources (e.g., Human Performance Data Repository, Design Reference Missions, Orion and ISS lessons learned, NHV  workshop reports, other relevant HRP Element gaps and research areas, ISS Crew Comments Database) to document the current state of the standards, guidelines, ground rules and processes, and identify information needed in HF HAB gap closure plans (HAB-01, -02 and -05).
  • With input from the Habitability Working Group, identify and refine critical mission attributes (e.g., critical task list, number of crew, length of mission, spacecraft typology, gravity, comm bandwidth) that will be necessary for determining, assessing and monitoring NHV and vehicle/habitat layout design in potential future human spaceflights.
  • Document the current guidelines, ground rules, and processes that define the state of knowledge for determining, assessing and monitoring NHV and vehicle/habitat layout design.
  • Obtain concurrence/approval from the appropriate review board(s).
Approach:



  • Utilize interviews, workshops and Technical Interchange Meetings (TIMs) as appropriate to gather subject matter expert and stakeholder knowledge, arrive at consensus on important issues, and vet products such as mission attributes and “current-state” guidelines.
  • Define mission attributes used for assumptions for initial estimates of volume risks based on data mining of existing and previous program products regarding vehicle/habitat layout design and NHV.
  • Use literature reviews and existing models to refine critical inputs for guidelines such as critical task volumes.
Target for Closure
Define and document the current state of guidelines, ground rules, and processes, and a refined set of critical mission attributes relevant for determining, assessing and monitoring Net Habitable Volume (NHV) and vehicle/habitat layout design. This information will refine the definition of the Risk of Incompatible Vehicle/Habitat Design and define acceptable levels of risk due to inadequate NHV and vehicle/habitat layout design.
