Astronauts always wear white uniforms. Why, if NASA's favorite color? And, do you know the clothes were heavy and thick.
As we all know, is the astronauts work in space. There is no atmosphere, so the astronauts face the threat of harmful radiation from the sun. The radiation is not filtered by the atmosphere like when on earth. Therefore, astronaut suits designed to prevent harmful radiation is "touched" the body of an astronaut.

Each material has a specific response to radiation. For example, if a material is reflective red radiation (wavelength 620-750 nm) and absorb radiation, then the material will look red to our eyes. The same principle applies to other colors such as yellow (wavelength 570-590 nm), green (wavelength 495-570 nm), and blue (wavelength 450-495 nm).
If a material does not reflect (aka absorb) all radiation, then the material will appear black to our eyes. That is why, when the dark, the color looks to our eyes is black, because there is no light radiation reflected into our eyes.
What about the white material? Light radiation dipantulkannya what?
Materials which appear white in our eyes is the material which is reflecting all radiation. This is the reason for the white material used astronauts clothing.Dangerous radiation astronauts can not reach the body as reflected back to space by the white material.
White clothing also serves to maintain the astronaut's body to keep warm, because the radiation emitted by the body it will terpantulkan astronauts back to the (not lost to space).
Equipment that must be
In addition to the uniform "should be" white, nothing else other equipment must use an astronaut (or cosmonaut, the mention of the Russians). NASA space outfit that has a cool name extravehicular mobility unit, aka EMU is also equipped with:

1. Helmet. Useful to protect astronauts from the sun, cosmic rays, charged particles, and so forth, but the astronauts were still able to see clearly.
2. Gloves and boots. Protective hands and feet, but can still move freely.
3. Tool Primary Life-Support System. This device is useful as peyediakan oxygen, air pressure regulator, and humidity, this perngkat packed like a shoulder bag, heavy.
4. Radio communications. You know that the vacuum can not conduct sound?Well, the radio communication allows the Astonot communicate with each other when outside the aircraft.
Thick spacesuits

1. Five layers nylom dialuminisiumisasi, five dialuminiumisasi mylar film, as pelidung heat.
2. Nylon-coated neoprene, as protector of the meteor shower with a relatively small size.
3. Layer structure of polyester / dacron, as protector of the difference in pressure with the outside environment.
4. Kemi layer of nylon bags / polyurethane, as protector of the state outside of the vacuum.
5. The hinges on the main points of the joints, which allow the astronauts to move in the heavy clothes.
6. Wrapping the body that comes with cold water, this allows the astronauts to do heavy labor, even more than six hours nonstop, but without the slightest sweat.
7. Thin layer of nylon, which is useful to make the astronauts feel comfortable, and easy to get in and out, in and out of these clothes.
Well, so if we see that Superman can fly into space without wearing extra clothes, or science fiction films are also nullify the importance of specific uniform in space, must be questioned again. Because, no special clothing is what will happen:
1. You will pass out in less than 15 seconds, coz there is no oxygen at all.
1. You will pass out in less than 15 seconds, coz there is no oxygen at all.
2. Blood and body fluids will boil, and then freezing out there because there is no air pressure at all. On the Moon, for example, the temperature there ranges from 120 ° Celcius when it gets sunlight, and -100 ° Celsius while the Moon does not get sunlight. Well, you will not survive temperatures as hot and cold as this!
3. You will be in jeopardy of cosmic rays and charged particles from the sun, not to mention the tiny particles such as dust and rock that moves at high speed. Ih scary huh?! So astronauts have to wear space suits!
