What is a space helmet?

The cosmic helmet has been one of the most famous symbols of the universe survey for decades. The iconic equipment appears in many aspects of both popular culture and scientific reality, including early film series for 30 years, such as Flash Gordon , B-Films such as Monster Robot The cosmic suit is necessary to keep the wearer's pressure in the harsh conditions of the universe. Meals, padding and thermal coverings.

Most cosmic helmets have a similar look-they tend to be both hard and in the shape of bubbles. The hard shell helps to maintain the pressure in the space vacuum. The shape of the bubbles is in most cases necessary because the helmet is attached to the space suit and does not rotate or move. The person who wears the connected helmet must be able to turn his head inward, resulting in a large cure form of the helmet.

Another common function of the space helmet is the Persore system. There were many types of models and names for the system, including the Lunar Extravehicular Side Assembly (Leva), Skylab Extravehicular Visor (SEVA) assembly, and an extravahicular (EVA or EVVA) assembly. The most important part of the hosting system is easily recognized in its gold color and is actually covered with a thin layer of gold. This view protects the wearer from the harmful rays of the sun, which are usually filtered by the Earth's atmosphere. Another shaded but may be included for protectionTransparent view. Naughty shades on the sides and the upper part of the host system can be pulled down if necessary to block the light.

Communication is another important aspect of the helmet. In some suit, microphones and headphones that connect to the radio system, they are built into the helmet so that explorers can communicate in space. Other suits have a separate piece of head worn under the helmet. This next piece is called a set of communication carrier in NASA suits and was nicknamed "Snoopy Cap" in popular culture.
