Because when in space you need to have an atmosphere of your own. Without one you wouldn't have any air. The moment you tried to inhale without a helmet... you'd implode.

What are space helmets made of?
Space helmets are usually made of a strong polycarbonate material for durability and protection from the vacuum of space. They also have specialized visors made of materials like gold coating to protect astronauts from harmful radiation and extreme temperatures in space. Inside, helmets have padding and ventilation systems to keep astronauts comfortable during spacewalks.
How did astronauts speak on the moon?
Astronauts communicated on the moon using radio transmissions through their space suits. They spoke into a microphone inside their helmets, which transmitted their voices to their fellow astronauts and mission control on Earth. The radio transmissions allowed for clear communication despite the challenges of being in space suits and helmets.
Why do astronauts wear a hat?
Astronauts wear helmets or space suits, not hats, to provide protection in space from extreme temperatures, micrometeoroids, and radiation. The helmet also ensures they have a stable supply of oxygen and communication.
What are facts about a space helmet?
Space helmets are designed to protect astronauts from extreme temperatures, micrometeoroids, and harmful radiation in space. They are equipped with a visor that can be adjusted to protect the eyes from the sun's glare and other bright lights. The helmets also contain communication systems to allow astronauts to speak with mission control and fellow crew members.
What materials are the space helmets made from?
Space helmets are typically made from a combination of materials such as high-strength plastics, polycarbonate visors, and reflective coatings to protect astronauts from space debris, extreme temperatures, and harmful radiation. The helmets also include padding for comfort and to help absorb impact in case of emergencies.
Why can astronauts hear on moon if they come close to each other so that their helmets touch?
Normally, to communicate in space, astronauts need radios. This is because sound (in this case, speech) requires a medium (such as air) to move through. In space, since there is no air, astronauts cannot talk to one another directly. However, in your case, the astronauts may converse because their helmets are touching - thus giving the sound waves a medium to move through - the helmets.
What do all astronauts have in common?
They all wear space helmets and eat the same things.
Why should the astronauts use a spacesuits and helmet while walking in the space?
Astronauts wear spacesuits due to the absence of pressure in space. They need to maintain the pressure level on Earth by isolating themselves from actual space. For the helmets: there is no oxygen in space. Humans require oxygen to live, inhaling it through their nose and mouth. Therefore if they do not wear helmets, they will die instantly from loss of oxygen.
What type of oxygen is in outer space that make us use helmets?
There is no oxygen in space. Astronauts have to take oxygen with them.

What do astronauts eat for lunch?
No, astronauts do not take off their helmets to eat. Astronauts do not normally wear their helmets except when exposed to the vacuum of space. They are not normally exposed to space when in a spacecraft (Apollo, Skylab, Shuttle, Space Station, etc.). They eat while in the spacecraft, so there is no need to remove their helmets.
When astronauts travel in space they must wear special helmets. Why?
The helmets are part of their space suits. They do not normally wear space suits unless they are going outside the spacecraft. Since there is no air outside and it can be very cold or hot. They need the suits to breathe and to protect them from the heat or cold and the vacuum of space which would kill them.

Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
How do they breath in space?
The astronauts breath as they have an oxygen tank which they keep attached with their space suit.
