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.


Why Do astronauts cannot hear each other on the moon?

Astronauts cannot hear each other on the moon due to the lack of air and atmosphere, which are necessary for sound to travel. Sound waves need a medium to propagate, and in the vacuum of space, there is no medium for sound to travel through. While astronauts can communicate through radios inside their helmets, they cannot rely on sound to transmit through the lunar environment.


Why can't astronauts communicate with each other in outer space?

Astronauts can communicate with each other in outer space using radio waves. However, the lack of atmosphere in space means there is no medium for sound to travel through, so they can't talk to each other in the same way we do on Earth. Instead, they use radio communication systems built into their spacesuits or spacecraft.


How many astronauts were abroad each space capsule launched during Nasa's Gemini space program?

i think but i am am not sure but i think it was 1-3 astronauts


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.

Can astronauts speak in space?

Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)


Astronauts on a space walk cannot hear each other. Why?

They can not hear each other through the natural environment due to there being no medium for the sound waves to travel through. However, they can hear each other through the use of radio communication.

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.
