Cis-Lunar was a company specializing in the production of automatic, computer-controlled, and closed-circuit rebreathers for astronauts and underwater divers. The company was formed in 1984 and was acquired by Stone Aerospace in 2004.{{Cite web |title=History of Expeditionary Exploration |url=https://stoneaerospace.com/history/ |archive-url= |archive-date= |access-date=2023-12-28 |website=Stone Aerospace}}
History
Cis-Lunar originally aimed to develop space suit kits, but the early 2000s recession reportedly hindered its ability to finance the mass production of the MK5 rebreather, which featured designs intended to reduce system and mission failures.{{cite journal |author=Stone |first=William C. |year=1986 |title=Design of fully redundant autonomous life support systems |url=http://archive.rubicon-foundation.org/9141 |url-status=usurped |journal=Diving for Science: Proceedings of the American Academy of Underwater Sciences Sixth Annual Scientific Diving Symposium.

In 2005, the Swedish diving equipment manufacturer Poseidon acquired Cis-Lunar's technology. Bill Stone, founder of Stone Aerospace, was appointed to lead a Poseidon team designing a new closed-circuit rebreather.{{cite web |title=Poseidon MKVI |url=http://www.poseidon.com/products/rebreathers/mkvi |url-status=dead |archive-url=https://web.archive.org/web/20120304040529/http://www.poseidon.com/products/rebreathers/mkvi |archive-date=2012-03-04 |access-date=2012-03-29 |website=Poseidon |publisher=}}
