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.
[1] 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.
[2] In 2005, the Swedish diving equipment manufacturer Poseidon acquired Cis-Lunar's technology.
