As we all know, space is full of various dangers. In addition to cosmic radiation, various microorganisms and fungi, there are only a few.
What about the clothes they wear? How does it manage to protect the astronauts?
Astronauts wear a jumpsuit in their spacesuit that serves for ventilation and cooling.

These overalls are made of elastic materials. It’s like a network of thin tubes. The water coming out of these pipes helps balance the body temperature of astronauts during space missions.
Astronaut suits consist of several parts. The part that covers the upper part of the body, It is made of fiberglass, a durable and hard material. Fiberglass is a glass-reinforced plastic.
Attached to this rigid body are the parts that protect the arms and legs. The flexible parts of spacesuits are made of multiple layers made of different materials occurs.
Each of these layers has different functions.

Thus, the outer layer is produced from the combination of three different materials. Even one of them It is a type of material used in bulletproof vests.The other two are waterproof and fire resistant.
7 different layers beneath the outer protective layer protect astronauts from against temperature changes and the damaging effects of small particles moving at high speed protects.
Because there is no air in space, certain substances that are liquid in the human body under normal atmospheric conditions can Keep the external pressure at the correct value to prevent it from turning into a gas must.
For this reason, spacesuits also contain a layer that is pressurized with oxygen.

The oxygen used in this system also allows astronauts to breathe. Helmets used in spacesuits, It must provide sufficient visibility for astronauts while fully fulfilling its protective duty.
For this reason, helmet visors protect astronauts from It is made of polycarbonate to protect it from the harmful effects of sun rays and high-speed particles.. It is also covered with a thin layer of gold particles.
In summary, the clothing astronauts wear allows them to move easily and simultaneously in space They are carefully produced and put into use to protect them from the harmful conditions in space.
