en.wikipedia.org/wiki/Space_suit

A space suit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon ...

The shell of the helmet is made of polycarbonate. Spacesuits are assembled at the headquarters of the National Aeronautics Space Agency in Houston. During space flights, they protect astronauts from potentially damaging conditions, and they serve as mobility aides when astronauts take a space walk outside spacecraft.

The next generation spacesuit was designed to protect against depressurization while the astronauts were in an orbiting spacecraft. However, space walks in these suits were not possible because they did not protect against the harsh environment of space. These suits were made up of five layers.

A space suit is composed of many layers of specialized fabric, including high strength composite materials, ortho-fabric, dacron, nylon/spandex, neoprene-coated nylon, urethane-coated nylon, tricot, aluminized mylar, and stainless steel. Each part of the space suit is made separately and then joined together.

NASA's first spacesuits were made for the Mercury program. Mercury was the first time NASA astronauts flew into space. The Mercury suits were worn only inside the spacecraft. NASA's first spacewalks took place during the Gemini program. Spacesuits for the Apollo program had boots made to walk on rocky ground.

What are space suits made of? Spacesuits are made of many different layers of material . Some of the layers protect astronauts from the temperature, which can really hot and really cold. Some layers protect them from micro meteorites that could fly into you at very high speeds, such as a material called Kevlar, which is almost bullet proof. ...

NASA astronauts first flew into space during the Mercury program. NASA’s first spacesuits were made for Mercury. The Mercury suits were only worn inside the spacecraft. NASA’s first spacewalks took place during its second space program, Gemini. The suits used for Gemini were better than the Mercury suits.

The space suit used for EVA during shuttle missions is the Extravehicular Mobility Unit (EMU), which has two parts: the space suit assembly (SSA), manufactured by ILC, and the life support system (LSS), manufactured by Hamilton Sundstrand (previously Hamilton Standard). The SSA is made of individual components which are assembled to fit each ...
