Cis-Lunar

This article is about the manufacturing company. For the astronomical term, see Outer space § Cislunar space.

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]

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.^[2]

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.^[3][1]

Etymology

The word cis-lunar comes from Latin and means "on this side of the Moon" or "not beyond the Moon".^[4]
