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.
The Lambertsen Amphibious Respiratory Unit (LARU) is an early model of closed circuit oxygen rebreather used by military frogmen. Christian J. Lambertsen designed a series of them in the US in 1940 (patent filing date: 16 Dec 1940) and in 1944 (issue date: 2 May 1944). [1]
The interior of the Apollo PLSS Diagram of the A7L PLSS and OPS, with interfaces to the astronaut and the Lunar Module cabin. The portable life support system used in the Apollo lunar landing missions used lithium hydroxide to remove the carbon dioxide from the breathing air, and circulated water in an open loop through a liquid-cooled garment, expelling the water into space, where it turned ...
Christian James Lambertsen (May 15, 1917 – February 11, 2011) was an American medical researcher. He was a environmental medicine and diving medicine specialist who was principally responsible for developing the United States Navy frogmen's rebreathers in the early 1940s for underwater warfare.
Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...
Bill Stone gave a talk at TED 2007 about exploring the world's deepest caves and frontier space travel. In the talk, Stone pledged his devotion to lead a mining expedition to the Moon "to mine ice thought to be trapped on the Moon's southern pole at Shackleton Crater, and to sell derived products (including propellants and other consumables) on the Moon and in low Earth orbit (LEO) to ...
The launch of the lunar landing could come just more than a year after Intuitive Machines ushered in America's first return to the moon in more than 50 years.. The 14-foot-tall Nova-C the lander ...
Research and development of carbon dioxide sensors goes back at least as far as the early 1990s when Teledyne Analytical Instruments and Cis-Lunar Development Laboratories worked on a sensor for the Cis-Lunar MK-III rebreather, which was accurate in laboratory conditions but in the field susceptible to high humidity and condensation causing ...
