The Constellation Space Suit was a planned full pressure suit system that would have served as an intra-vehicular activity (IVA) and extra-vehicular activity (EVA) garment for the proposed Project Constellation flights. The design of the suit was announced by NASA on June 11, 2008, and it was to be manufactured by Houston, Texas-based Oceaneering International, the 4th company after the David Clark Company, Hamilton Sundstrand, and ILC Dover (and, before 1964, B.F. Goodrich) to produce life-support hardware, as a prime contractor, for in-flight space use. Design The Constellation Space Suit system was designed by NASA for Constellation program due to the needs of reducing space on board the relatively small (by current standards) Orion spacecraft, and at the same time, would protect the astronauts during launch, reentry and landing, and extreme emergencies (such as a cabin depressurization). Another need for NASA was that the suit system must be capable of withstanding the rigors of microgravity EVAs, and with modifications, from the rigors of lunar surface EVAs during a 7-day lunar sortie, with the provisions for 6-month stays once the Lunar Outpost is completed. As the Apollo/Skylab A7L, ACES, and Shuttle/ISS Extravehicular Mobility Unit (EMU) pressure and space suits were deemed unsuitable for NASA's needs for Project Constellation, a new suit system was designed and is designated as "Configuration One" (IVA/Microgravity EVA) and "Configuration Two" (Lunar EVA). Configuration One The "Configuration One" suit, worn for launch, landing, for extreme emergencies, and for microgravity EVAs, will resemble the current ACES pressure suit used by NASA astronauts on Space Shuttle flights. Unlike the current suit, which were based on the G3C suit worn by the Gemini 3 crew and later adapted for use by the U.S. Air Force for high-altitude operations, the "Configuration One" suit will feature a closed-loop environmental system (similar to that of a rebreather – the ACES suit uses a SCUBA-like open-loop system, limiting its operations above ), new bearings in the shoulder, elbows, wrists, hip, and knees, and a full-pressure helmet with a swivel faceplate (closed by a mechanical seal) and incorporating a sunshade. Like the older G3C suit, the "Configuration One" suit will be made up of five layers, the innermost being a rubberized pressure-retaining bladder made of neoprene cloth, and covered with a Nomex cover layer in international orange color. In the event a microgravity EVA is conducted, instead of the Primary Life Support System backpack worn
