Without the benefit of Earth's atmosphere, astronauts need devices such as this one to keep them alive during their missions. This emergency life support system was developed during training for Gemini missions. It allowed astronauts to control the flow of oxygen into their spacesuits and would have been affixed to their chest pack. This unit was redesigned to minimize its size and weight for use in space.
The unit's designer, LTV Aerospace Corporation, donated this version to the Museum in 1973.
