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. 


  1. 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.
  2. Verify model throughout the model development process.
  3. Extend to Design Reference Missions to cover other mission durations and parameters.
  4. 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.
