Controlled Ecological Life Support Systems (CELSS) utilize plants for food, air, and water regeneration. Key factors like light and waste management are crucial for developing effective space life support.

Area of Science:

  • Space Biology
  • Environmental Engineering
  • Life Support Systems

Background:

  • Controlled Ecological Life Support Systems (CELSS) are critical for long-duration space missions.
  • Plant-based systems offer multifunctional life support capabilities.

Purpose of the Study:

  • To provide an overview of CELSS concepts and influencing environmental factors.
  • To explore plant growth systems and their space applications.
  • To analyze the integration of biological and physical-chemical life support techniques.

Main Methods:

  • Review of environmental factors (gravity, light, growth volume) impacting CELSS design.
  • Description of various plant growth systems and their space applications.
  • Analysis of life support functions: food production, atmosphere regeneration, water purification.

  • Examination of human nutritional, water, and atmospheric requirements.
  • Discussion of waste generation and nutrient recovery systems (biological and physical-chemical).

    • Main Results:

    • Plants perform vital life support functions including food production, atmosphere regeneration, and water purification.
    • Human requirements are primary drivers for CELSS design, influencing waste management strategies.
    • Nutrient recovery from waste is essential for sustainable plant growth in space.
    • Subsystems like nutrient recovery, plant irradiation (including fiber optic solar), and environmental controls are critical.

    Conclusions:

    • CELSS design must consider environmental factors and integrate biological and physical-chemical processes.
    • Efficient waste management and nutrient recovery are vital for closed-loop life support.
    • Optimized plant growth conditions and subsystem integration are essential for successful space applications.
