Aims:

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 is directly drives mass and cost, this information is needed early in the design process.

Develop a constrain-driven, optimization-based model that can be used to estimate and evaluate spacecraft/habitat volume.
- Estimate spacecraft/habitat volume based on mission parameters and constraints,
- Provide layout assumptions for a given volume,
- Assess volumes based on a set of performance metrics, and
- Inform risk characteristics associated with a volume.
Verify model throughout the model development process.
Extend to Design Reference Missions to cover other mission durations and parameters.
Provide validation of the SOLV model.

Integration/Unique Aspects:
This task may also address several other risks of potential HRP customers such as HHC and ExMC.

The team has developed key driving requirements; developed a documentation plan for adherence to NASA-STD-7009; developed a draft Verification and Validation Plan; and begun work on implementation of multiple major components of the code that will comprise the Spacecraft Optimization Layout and Volume (SOLV) model.

Risk of an Incompatible Vehicle/Habitat Design

HAB-05: We need to identify technologies, tools, and methods for data collection, modeling, and analysis that are appropriate for design and assessment of vehicles/habitats (e.g., net habitable volume, layout, and usage) for predetermined mission attributes, and for refinement and validation of level of acceptable risk.
