The suit is a direct descendant of the U.S. Air Force high-altitude pressure suits worn by the two-man crews of the SR-71 Blackbird, pilots of the U-2 and X-15, and Gemini pilot-astronauts, and the Launch Entry Suits (LES) worn by NASA astronauts starting on the STS-26 flight, the first flight after the Challenger disaster.
Cross-section of layers in space suit construction. An (Integrated) Thermal Micrometeoroid Garment (TMG or ITMG) is the outer layer of a space suit.The TMG has three functions: to insulate the suit occupant and prevent heat loss, to shield the occupant from harmful solar radiation, and to protect the astronaut from micrometeoroids and other orbital debris, which could puncture the suit and ...
A U-2 pilot suit. A pressure suit is a protective suit worn by high-altitude pilots who may fly at altitudes where the air pressure is too low for an unprotected person to survive, even when breathing pure oxygen at positive pressure. Such suits may be either full-pressure (e.g., a space suit) or partial-pressure (as used by aircrew). Partial ...
The image shows the complete multi-layer suit and positive-pressure helmet, lacking only the backpack. (taken c. 1971) A mechanical counterpressure (MCP) suit, partial pressure suit, direct compression suit, or space activity suit (SAS) is an experimental spacesuit which applies stable pressure against the skin by means of skintight elastic ...
In a dependent space suit (such as the ones used in the Gemini program or within lunar orbit on the Apollo program), the heat is carried back to a host spacecraft through an umbilical connection, where it is ultimately radiated or sublimated via the spacecraft's own thermal control system.
The space suits functioned as individual, personalized space crafts designed to keep a human alive in the environment of space or the lunar surface. The production line at ILC followed NASA-mandated engineering guidelines that were significantly stricter than typical clothing manufacturing processes. Tolerance for variation in the stitches were ...

Beta cloth is a type of fireproof PTFE impregnated silica fiber cloth used in the manufacture of Apollo/Skylab A7L space suits, the Apollo Thermal Micrometeoroid Garment, the McDivitt Purse, [1] and in other specialized applications. Beta cloth consists of fine woven silica fiber, similar to glass fiber. The resulting fabric does not burn, and ...
