Astronauts are characters who have repeatedly received the title of heroes. And it’s no less, because these hardened men must perform strong physical and mental training to make trips to other planets.
An exclusive wardrobe
But in order to carry it out, they must have an apparel that is very attractive to the eye, but beyond the aesthetic, the main function of this costume is survival.
Within the spaceships and ferries that leave our atmosphere, the atmosphere is modified so that man can move freely. When leaving the ships, to investigate the surroundings, they must load a portable terrestrial environment, the primordial feature of an astronaut costume.
The clothing becomes a mini reproduction of the environment in which a human being would be at sea level, but the gas that is introduced into the suit is 100% pure oxygen; so an astronaut inside his suit sucks in more oxygen than a man who lives on a coast. This gas is used to remove nitrogen that builds up in bodily fluids and thus prevent distressing diseases such as stroke.
One of the few places on earth that closely resembles microgravity conditions on a spacewalk is within drinking water. Nasa (The National Aeronautics and Space Administration) uses pure water pools to perform the respective costume tests.
The US company Hamilton Standard is in charge of manufacturing and maintaining the equipment of Nasa employees. Before each mission, this company must deliver 14 suits with the respective performance tests.
An astronaut suit looks more like a telecommunications network system, as it is a swarm of cables and interconnects that in turn serve to emit and receive shortwave signals. Each corner of the suit is designed to attach a strap pocket, which is used to store the tools that may be used in the mission.
The complete suit consists of a thermal mesh, an electric belt for extra vehicular activity; a urine collector, a torso protector, a semi-pressurization part, a helmet for extra vehicular activity, a communication system, an adapter for the life support system, a control module, a primary life support system, gloves for extra vehicular activity, a secondary oxygen supply, an umbilical refrigerator, an environmental pollution control and a battery.
This complex suit comes to weigh approximately 120 kilos, the white outer layer is of a material that reflects light to fade the heat.
Inside the suit, there is a mesh that protects the interior fabrics, from possible tears. It is known as the kevlar layer, also consists of mostly cotton and provides a pleasant touch to the astronaut. In addition, it has a faster absorption of sweat.
