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.
What else can I help you with?
When astronauts travel in space they must wear special helmets. Why?

How does sound get through space helmets?
Sound cannot travel through space because it requires a medium, such as air, to propagate. In space, there is a vacuum, so sound waves are unable to travel. However, astronauts can communicate with each other through space helmets by using radio transmissions or bone conduction technology that bypasses the need for air as a medium for sound.
Why do astronauts need helmets in space?
Astronauts need helmets in space primarily to provide life support by supplying oxygen and regulating temperature. Helmets also protect against the vacuum of space, which can cause bodily harm due to lack of pressure. Additionally, they shield astronauts from harmful radiation and micrometeoroids. Finally, the helmet's visor helps protect their eyes from intense sunlight and glare in the space environment.
Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
Will astronauts hear each other if their helmets are touching?
Yes, astronauts can hear each other if their helmets are touching because sound can be transmitted through solid materials. When their helmets make contact, vibrations can travel through the helmet material, allowing sound waves to pass between them. However, in the vacuum of space, they would not be able to hear each other through the air, as sound cannot travel in a vacuum.
What do all astronauts have in common?
They all wear space helmets and eat the same things.
How do astronauts hear each other when they touch helmets?
Astronauts can hear each other when they touch helmets because their spacesuits are equipped with communication systems that include microphones and earpieces, allowing them to transmit and receive sound even in the vacuum of space. When helmets make contact, the vibrations from their voices can also travel through the material of the helmets, enabling them to hear each other more clearly. This combination of technology and physical contact allows for effective communication in the challenging environment of space.
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 do you speak in space?
In space, sound waves cannot travel because there is no medium for them to travel through. Therefore, astronauts communicate with each other using radios and headsets inside their helmets. They talk and listen to each other through the radio system.
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 are people who travel space called?
People who travel in space are called astronauts.
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.
