Astronauts are the kind of people who look at the world and think, “We can do better.”
They’re the ones who don’t just sit back and let things happen, they make things happen. They’re the ones who aren’t afraid to dream big and go after their dreams. They’re the ones who will tell you that if you want something badly enough, you can have it—even if it seems impossible.
And they’ll help you get there too.

What do astronauts wear in space?
Space is a very challenging place to explore. There is no air in space, so there is nothing to breathe. It is very cold, unless the sun is shining onto you – and then, without air to protect you, the rays of the sun would soon burn you!
To survive in space you need a suit that protects your body from the heat and cold, and surrounds you with air to breathe. Space suits are pressurised, meaning they are full of air to support your body, which is why they look puffed up.
A space suit is like a tiny spaceship for one. It is a very complicated machine, with air conditioning, heating, air to breathe and water to drink. It even has a built in toilet!
Some space suits attach to a rocket powered backpack, which allows the astronaut wearing it to fly around in space.
Spacesuits were first invented around 80 years ago, for early pilots who wanted to fly really high. As pilots fly higher and higher, the air becomes thinner, so they need air to breathe and to support their bodies. The earliest suits were made of rubber and cloth and were stiff, bulky and hard to move around in.
In the 1950s and 1960s, Russia and America got into a race to be the first into space. Although the earliest astronauts stayed inside their spacecraft, scientists knew they needed protection, and so started work on better space suits for these missions.
The first NASA spacesuits were silver in colour, because scientists thought this would reflect the burning hot sun rays. They had hoses on them that were attached to machines that kept them supplied with air and cooling water. The picture on the left shows the first seven NASA astronauts, selected from the best Airforce test pilots, to fly on the Mercury space missions that put the first Americans into space.
What do astronauts wear on their head?
In space, astronauts wear a helmet. The helmet is their protection from the vacuum of space and the rays of the sun. It’s also their way to communicate with each other and with mission control.
On the inside of the helmet, there’s a communication system that allows astronauts to talk to each other and communicate with mission control. It also has a microphone so astronauts can hear what mission control is saying. The speakers are built into the suit itself so they’re always on hand when you need them!
What is a Space Helmet?
The space helmet has been one of the most recognizable symbols of space exploration for decades. The iconic piece of equipment has show up in numerous aspects of both popular culture and scientific reality including the early movie serials of the 1930s like Flash Gordon, B-Movies such as Robot Monster in the 1950s, photographs of helmet-wearing astronauts on the moon from the 1960s and 1970s, and the videos of spacewalkers repairing the International Space Station (ISS). The space helmet is one of the most important parts of a space suit, and is required for survival in the harsh conditions of outer space.
The space helmet fulfills three primary purposes and many smaller ones. First, it allows pressure to be maintained around the wearer’s head while in the vacuum of space. Second, the space helmet provides breathable oxygen for the person wearing it. Third, the helmet allows the wearer to see, while also providing protection against extreme light, radiation, and other harmful rays. The helmet can also house other important items including communications gear, water, food, padding, and thermal coverings.
Most space helmets have a similar look to them – they tend to be both hard-shelled and bubble-shaped. The hard shell assists in maintaining pressure in space’s vacuum. The bubble shape is necessary in most cases because the helmet is attached to the space suit and does not turn or move. The person wearing the attached helmet must be able to turn their head inside of it, resulting in the helmet’s large bulbous form.
Another common space helmet feature is the visor system. There have been many model types and names for the system, including the Lunar Extravehicular Visor Assembly (LEVA), Skylab Extravehicular Visor Assembly (SEVA), and Extravehicular Visor Assembly (EVA or EVVA). The most prominent part of the visor system is easily recognized by its golden color, and is, in fact, coated by a thin layer of gold. This visor protects the wearer from the sun’s harmful rays that are normally filtered by the Earth’s atmosphere. An additional shaded but transparent visor may be included for protection. Opaque shades on the sides and top of the visor system can be pulled down to block light when necessary.
Communication is another important aspect of the helmet. In some spacesuits, microphones and earphones that connect to a radio system are built into the helmet so that explorers can communicate while in space. Other spacesuits have a separate piece of headgear that is worn under the helmet. This additional piece is called the Communications Carrier Assembly in NASA suits, and has been nicknamed the “Snoopy Cap” in popular culture.
Why do astronauts wear pressurized suits
Astronauts must wear spacesuits whenever they leave a spacecraft and are exposed to the environment of space. In space, there is no air to breath and no air pressure.We know, air only flows from high pressure to low pressure. Space has zero air pressure. Our lungs always has some air pressure.
So, if astronaut moves to space, without pressurized suits, the air from his lungs will move to outside space ( low pressure) but he cannot breathe in air, as pressure in lungs is never lower than space press ure (which is zero). The only way he can breathe is, by creating a lower pressure in lungs, which is impossible.
Lungs can only create small pressure differences.So, astronaut will choke to death.When pressure suits are provided, atmospheric pressure is maintained around him in his suit, and his lungs can easily take in and leave out air.So, pressure suits are necessary.
