Bioregenerative life support system

Bioregenerative life support systems (BLSS) are artificial ecosystems consisting of many complex symbiotic relationships among higher plants, animals, and microorganisms. As the most advanced life support technology, BLSS can provide a habitation environment similar to the Earth's biosphere for space missions with extended durations, in deep space, and with multiple crews.[1][2][3]
