How do astronauts protect people?

We still often wonder how miraculous the astronaut's protective suit is to help people survive in space. So let's find out the interesting information that revolves around the astronaut wearing clothes before going out into space in this article.

According to CosmosMagazine, the previous astronauts who stepped out of the space station to carry out missions, they will have two options with NASA astronaut introduced in 1984 and Russian Orlan suit in the chapter. submitted to Russian space launched in 1960. Over the decades of innovation, the astronaut suit has had more modern changes.

Through decades of innovation, astronaut suits today have made more modern changes.

Not only are they able to provide oxygen, regulate body temperature, or even support the hygienic conditions, astronaut suits also function to protect against debris flying around the Earth. However, these are just general functions. To gain a deeper understanding of the functions of each part of a suit, readers can learn more in the information below:

Helmet

A place to protect the head and also a place to store oxygen provided from oxygen tanks to provide life for astronauts. The inside of the helmet is a transparent plastic sheet. If the astronauts are thirsty, they can bite a small tube and suck the liquid contained in a bag of about 0.95 liters capacity mounted inside the cap.

The inside of the helmet is a transparent plastic sheet.

Inside the astronaut's helmet is also equipped with another special hat called snoopy cap . This hat is often attached to a mic to keep in contact between astronauts and crew.

Snoopy cap.

The outer part of the hat that surrounds the plastic sheet is covered with a gold-plated layer to protect the skin from ultraviolet rays, glare and protect the camera from close-up astronauts (the crew can also see everything work in real time from the camera). The outer caps are made of polycarbonate, a hard and light enough material to make bulletproof glass, but their use in outer space to avoid small debris from meteorites and other debris can hit Touch with astronauts.

Upper body

The upper body is the armor that protects the body from the neck to the astronaut's abdomen. It is also in this armor that supports the life and control of modules of the entire map.

In this armor is a place to support life and control the modules of the entire map.

The display and control modules are mostly placed in the front. There, astronauts can adjust a lot of settings including temperature, mass and oxygen.

An equally important part is the rope attached to the astronaut with the spacecraft to avoid being washed away in a zero gravity environment. This wire is connected to the upper body via a port called D-ring ( D- shaped).

An equally important part is the rope attached to the astronaut with the spacecraft.

Even if the unfortunate astronaut is separated from the spacecraft, the suit also acts like a relief buoy. Through the ability to blow nitrogen to push forward, combined with a steering wheel, astronauts can navigate to quickly return to the safe ship.

Arm

The arm part is attached to the body and there are many different sizes to fit the arm length.

Arm parts include 14 layers. The first three layers closest to the skin are woven fabrics made from nylon and spandex has a cooling and ventilation effect on the skin. Nylon material works to maintain pressure, while woven fabric made from polyethylene terephthalate (PET) will help maintain the shape of the suit.

Arm parts include 14 layers.

Next is another nylon fabric, and is covered by 7 layers of aluminum alloy aluminum polyester (Mylar) that works against meteorite debris and small debris that can pierce through the suit. The remaining outer layers are made of materials that combine Gore-Tex, Kevlar and Nomex with water, bullet and fire resistance.

This glove comes with a work checklist right on the wrist.

Attached to the arm parts are gloves. Astronauts can easily turn their wrists, especially this part also functions to warm your fingers if you feel cold when you are in space. Interestingly, this glove comes with a work checklist right on the wrist, so that astronauts can get a detailed idea of ​​what to do immediately.

Lower body

Is the astronaut's lower body protection. This unit is connected to the upper body via a rack, and the wearer can rotate and move easily and comfortably.

This part is connected to the upper body via a support.

A screw system is used at the coupling point between the lower body and the shoe. Especially the astronaut's shoes used in outer space have almost no small grooves to create friction as usual.

Astronauts are wearing a very special adult diaper called the Maximum Absorbency Garment (MAG).

Of course there will be many missions out of space that last for hours, which poses a concern if the astronaut is "sanitary" , things will get very bad. Fortunately, the astronauts wear a very special adult diaper called the Maximum Absorbency Garment (MAG). This is a very good fabric that absorbs urine and feces. However rarely MAG is used in outer space. The purpose of wearing MAG helps provide astronauts peace of mind when performing tasks outside the space station.

Life support system

The system of life support devices for astronauts is attached to the back. This system includes a lithium hydroxide respirator that filters CO2 in the air at the astronaut's airway by producing Li2CO3 (lithium carbonate) and water, much like the snorkelers of underwater divers. .

Next is the oxygen tank, the most important source of pure oxygen for astronauts. Oxygen will always be blown and transmitted regularly through a battery-powered blower. Such an oxygen tank can supply the astronauts with oxygen for 7 consecutive hours and more than half an hour of storage in an emergency.

This system provides cooling water to control and balance temperature, absorb sweat and prevent condensation. Especially, the system also integrates astronaut warning function in case of malfunction.

An astronaut looks cumbersome and entangled but it is a means of protecting life when out of space so far humans can do it.

You may have seen it on TV or somewhere, an astronaut looks bulky and entangled. Even so, it is possible for all people to protect life when they are out of space. Of course, in the future, under the hands of human talents, the clothes may become more compact and more convenient for astronauts.
