Autonomous life support systems are crucial for long-term space missions. A Lunar Engineered Closed/Controlled EcoSystem (LECCES) integrates plant, animal, and waste modules to minimize Earth resupply needs.

Area of Science:

  • Space exploration
  • Bioregenerative life support systems
  • Ecosystem engineering

Background:

  • Long-term human space missions, including lunar bases, necessitate highly autonomous life support systems.
  • Current systems often require significant resupply from Earth, limiting mission duration and scope.
  • Developing closed-loop ecological systems is key to enabling sustainable off-world habitation.

Purpose of the Study:

  • To propose a conceptual design for a Lunar Engineered Closed/Controlled EcoSystem (LECCES).
  • To outline the integration of various modules for a bioregenerative life support system.
  • To address the requirement for autonomy in supporting human presence on the Moon.

Main Methods:

  • Development of a top-level architectural diagram for LECCES.
Keywords:
NASA Discipline Life Support SystemsNon-NASA Center

Related Experiment Videos

  • Analysis of human module requirements to inform system design.
  • Discussion of integrated physical/chemical and biological waste treatment subsystems.

    • Main Results:

    • A conceptual diagram for LECCES has been developed.
    • The integration strategy emphasizes combining different waste treatment approaches.
    • The proposed system aims to achieve a high degree of autonomy.

    Conclusions:

    • LECCES offers a viable pathway toward autonomous bioregenerative life support for lunar bases.
    • Integrating physical/chemical and biological waste treatment is essential for minimizing resupply.
    • The conceptual design provides a foundation for future development of lunar life support systems.
