Area of Science:

  • Biochemical stoichiometry
  • Systems biology
  • Space life support

Context:

  • Developing advanced biological life support systems (BLSS) for long-duration space missions requires robust simulation models.
  • Current models need detailed biochemical data to accurately represent system dynamics and resource closure.

Purpose:

  • To develop comprehensive biochemical stoichiometry for key components within a space-based biological life support system.
  • To model plant biomass production, human metabolic outputs, and waste processing operations.
  • To establish a foundational model for a steady-state, wheat-based, materially-closed BLSS.

Summary:

  • Developed detailed biochemical stoichiometry for protein, carbohydrate, fat, fiber, and lignin in plant production (edible and inedible).
