Gemini Space Suit - Specifications

Specifications

The suit family system included both parachute and flotation systems. For EVAs Gemini 4 used the Ventilation Control Module (VCM), for Gemini 8-12 the Extravehicular Life Support System (ELSS) was used. The ELSS was also designed to optionally supply autonomous life support though they never made it to EVA, two oxygen supply packs were developed for it, one was the Extravehicular Support Package (ESP)(provide an hour's worth of life support) carried aboard Gemini 8 but not used and the other for the Astronaut Maneuvering Unit (provide an hour's worth of life support) carried on-board Gemini 9 and to fly while tethered but was not used. The AMU was also meant to be launched and flown on-board Gemini 12, and to fly untethered from the Gemini spacecraft but was scrubbed two months before the mission.
