A key design challenge for future long-duration exploration missions is determining the appropriate volume of a spacecraft/habitat to accommodate habitability functions and ensure optimal crew health, performance, and safety. Because spacecraft/habitat volume directly drives mass and cost, this information is needed early in the design process. The objective of this study was to develop a constraint-driven, optimization-based model that can be used to estimate and evaluate spacecraft/habitat volume.
To accomplish this, the team was structured to leverage expertise from diverse fields, including architecture and habitation design, human factors engineering, industrial engineering, optimization-based modeling, and simulation. A computational model for spacecraft/habitat volume is an invaluable tool for designers, mission planners, integrators, and evaluators who are shaping space habitats and working toward a truly habitable environment for future long-duration exploration missions.
The computational model development was completed through four specific aims:
Investigators developed a model that can be used to measure spacecraft and habitat volumes. This involved selecting a software platform; developing model requirements; defining model inputs, outputs, and constraints; developing strategies for optimization approaches; and working on verification and validation plans.
The SOLV project successfully conducted the Final Design Review (FDR) on 3/7/2018. SOLV achieved this project milestone on schedule, meeting all its objectives. A compliance assessment performed by the SOLV team indicated that the prototype model meets the established goals in credibility factors such as verification, validation, data pedigree, uncertainty characterization, and results robustness, as defined by NASA-STD-7009A. The team also provided an out brief and a model demonstration to the Human Research Program (HRP) and Human Factors and Behavioral Performance (HFBP) teams and HHP/SF management at the conclusion of the FDR. Investigators delivered the SOLV model and associated software files, and seven project documents capturing the project’s technical approach, verification and validation plans, test results, software specification, and development plans to the HFBP team.
