NASA is developing Controlled Ecological Life Support Systems (CELSS) for long space missions. These systems mimic Earth

Area of Science:

  • Space exploration
  • Ecological engineering
  • Life support systems

Background:

  • NASA Ames Research Center is developing life support technologies for long-duration space missions.
  • The Controlled Ecological Life Support System (CELSS) Program aims to create small-scale ecological systems mimicking Earth's ecosystems.

Purpose of the Study:

  • To outline plant selection and waste-processing requirements for CELSS.
  • To characterize waste streams within a CELSS.
  • To discuss physical/chemical waste processors and nitrogen recovery.

Main Methods:

  • Review of plant selection criteria for space habitats.
  • Analysis of waste stream composition from human and plant sources.
  • Evaluation of physical/chemical waste processing technologies.

Related Experiment Videos

  • Assessment of nitrogen recovery efficiency in waste processing.

    • Main Results:

    • CELSS aims for near 100% waste recycling for life support.
    • Plants are crucial for air purification, water cleaning, and food generation.
    • Nitrogen recovery from waste is a critical factor for nutrient cycling.

    Conclusions:

    • CELSS technologies are essential for sustainable long-duration space missions.
    • Integrated physical/chemical and biological systems are considered for waste recycling.
    • Efficient nitrogen management is key to the success of CELSS.
