A new Linear Programming model helps select crops for Controlled Environment Life Support System (CELSS) food production. This model optimizes astronaut nutrition and culinary satisfaction by considering crop yield and nutritional content.

Area of Science:

  • Agricultural Engineering
  • Nutritional Science
  • Space Systems Engineering

Background:

  • Controlled Environment Life Support Systems (CELSS) are crucial for long-duration space missions.
  • Selecting optimal crops for CELSS food production requires balancing nutritional needs with environmental constraints.
  • Previous crop selection methods may not fully integrate nutritional, yield, and human factors.

Purpose of the Study:

  • To develop a Linear Programming model for selecting crops in CELSS food production.
  • To ensure astronaut nutritional requirements are met through optimized crop selection.
  • To enhance the culinary acceptability of food produced within a CELSS.

Main Methods:

  • Construction of a Linear Programming model integrating nutritional content and controlled-environment production yields.

  • Inclusion of diverse expertise from Controlled Environment Agriculture (CEA) specialists.
  • Framework development for constructing a crop mix tailored to astronaut needs.

    • Main Results:

    • The model can identify a minimal set of crops to meet nutritional requirements (with supplements).
    • The model demonstrates flexibility in incorporating culinary preferences and variety.
    • Optimized crop selection can satisfy basic nutritional needs for space crews.

    Conclusions:

    • Linear Programming provides a robust framework for CELSS crop selection.
    • Balancing nutrition and culinary factors is key for astronaut well-being in space.
    • The developed model offers a flexible approach to sustainable food production in controlled environments.
