CELSS

Controlled (or Closed) Ecological Life Support Systems (acronym CELSS) are a type of scientific endeavor to create a self-supporting life support system for space stations and colonies typically through controlled closed ecological systems, such as the BioHome, BIOS-3 and Biosphere 2.

CELSS was first pioneered by the Soviet Union during the famed “Space Race” in the 1950s-60s. Originated by Konstantin Tsiolkovsky and furthered by V.I. Vernadsky, the first forays into this science were the use of closed, unmanned ecosystems, expanding into the research facility known as the BIOS-3.
