Biological Life Support Systems (BLSS) close the food cycle for long space missions, reducing logistics costs by recycling waste and producing food. These biotechnical systems integrate humans, plants, and microbes with hardware for sustainable space exploration.

Area of Science:

  • Space exploration
  • Biotechnology
  • Ecology

Background:

  • Conventional life support systems face logistical challenges for long-duration space missions due to storage and launch weight.
  • Closing the carbon/food recycling loop is essential to reduce costs and enable sustainable space travel.

Purpose of the Study:

  • To define requirements, concepts, and feasibility of Biological Life Support Systems (BLSS) for space applications.
  • To analyze the energy-mass relation of BLSS and identify advantages over physico-chemical systems.

Main Methods:

  • Integration of human, animal, plant, and microbial elements with mechanical and physico-chemical hardware.
  • Analysis of energy-mass relations and influence factors for BLSS optimization.
  • Review of recent space experiments and intensified studies in ecological life support systems.

Main Results:

  • BLSS can satisfy space station environmental control functions and close the food cycle.
  • Energy-mass relation analyses determined potential advantages of BLSS.
  • Major problem areas requiring attention were identified.

Conclusions:

  • Biological Life Support Systems are crucial for sustainable, long-duration space missions.
  • Further development and research are needed to address identified problem areas.
  • A development program for BLSS has been proposed.
