During the summer of 2020, the NASA Mars Architecture Team (MAT) assessed the Enhanced Habitation Capability (EHC), the transit spacecraft that was part of what was then the current Mars human exploration architecture, the Basis of Comparison (BOC). This assessment had six primary objectives: provide a sanity check to the BOC-derived EHC layout; understand if we can fit the hardware and functional tasks in the volume; provide a high-level assessment of how aggressive the layout is; generate a list of challenges or assumptions necessary to make it work; generate a list of future work to refine understanding; and identify proposed requirements. The results of this evaluation are discussed, including methodological challenges and rating challenges. Acceptability results are discussed for functions that the participants were able to rate and participant comments for functions that could not be evaluated are also described. Final conclusions are described, including challenges or assumptions needed to make the EHC design acceptable, future work needed to refine understanding of the EHC, and proposed habitat requirements based on test data. While NASA has since moved away from the BOC architecture, this assessment is still useful to inform the design of future Transit Habitats.
