In space, there is no wind or something to carry the sound waves. Sound waves must travel for people to hear. For example, if an explosion took place in space, you will not hear anything because the sound waves created by the explosion won't travel.

∙ 10y agoThere's no sound in space because sound is vibration through a medium, such as air or water. For a long time people thought there must be a medium they called aether in space for light waves to travel through, but as it turns out, light (actually all electromagnetic radiation, including radio and gamma rays) doesn't need a medium. So in a way you CAN "hear" from space when EM radiation is converted into sound by electronic devices.

∙ 13y agoNo as there is no air in space sound can not travel so they use radios.

∙ 8y agoYes. The statement that there is no sound in space comes from the fact that sound cannot travel through a vacuum. A manned spacecraft is filled with air, so sound can travel freely within it.

Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
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.
Why can astronauts not talk to each other without communication equipment on the moon?
There is no air on the moon. Sound waves only propagate through a medium, such as air, water, etc. Sound waves cannot propagate through a vacuum, therefore the astronauts had to use radios to speak to each other.
Do astronauts sleep in outer space?
Yes. Extra Fact: When in space, no one can hear you scream.
Do shuttle astronauts cease to hear engine thrust sounds once the shuttle and rockets exceed the speed of sound?
yes
Can astronauts hear each other?
As there is no air , it is difficult , but astronauts use 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 astronauts cannot hear each other in space?
Space is vacuum, and sound can't travel in vacuum.
Why is it when 2 astronauts have their helmets touching they can hear each other why?
because the sound waves travel through the metal of the helemets.
Can you hear can you hear through space suits?
Indeed! You can't hear what's going on around you, but you can hear other astronauts through their radio.
Why Do astronauts cannot hear each other on the moon?
Sound cannot travel through medium because it does not contain any particles to pass on the sound vibrations
Why can 2 astronauts on a spacewalk see each other but not hear each other without radios?
Since there is no air, the sound waves would not travel. Radio waves being electromagnetic do not rely on matter (atmosphere) to conduct them.

To hear astronauts in space the sounds waves are converted to?
rocket

What is the homophone of here-hear?
They are homophones of each other.
