The light waves they reflect travel through empty space but sound waves do not.

Do astronauts sleep in outer space?
Yes. Extra Fact: When in space, no one can hear you scream.
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.
Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
Would astronauts on the Moon be able to hear a rocket engine?
I hope so. However, if they see something that would be noisy on the Earth, but in space, like a rocket firing, they would not hear it in space, because sound needs a medium to travel through, like air. There is no air in space, it is mostly a vacuum. So the only sounds an astronaut should hear are his radio, his breathing and anything tapping on his helmet (the air in the helmet will transmit sound waves to his ears).
Can astronauts hear in space?
Sound doesn't propagate in space, or in any place without an atmosphere such as the surface of the moon. Sound is mechanical energy, and the energy must be "put into" the material (gas, liquid, solid) that is used to propagate it. This is in contrast to electromagnetic energy, like light, which is "self-contained" and can move through the vacuum of space. Astronauts can communicate by normal conversation inside a spacecraft or in the International Space Station. This is because pressurized air is introduced to simulate conditions on the earth (and allow astronauts to breathe). They can talk normally and be heard. But during a "space walk" or on the surface of the moon, all communication is by radio, even between individuals who are only a few feet apart. An interesting note is that two individuals who are "outside" can turn off their communications gear, press their face plates together, and have a conversation that no one else can hear. This lends new meaning to the term private conversation.
What conditions must astronauts prepare for when traveling to space?
No one being able to hear them scream.
To hear astronauts in space the sounds waves are converted to?
rocket

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 astronauts cannot hear each other in space?
Space is vacuum, and sound can't travel in vacuum.
How can people hear astronauts voices from space?
The voices are transmitted via radio.
How do astronauts hear in space?
They can't because sound needs something to bounce of like air.
Would astronauts be able to hear an explosion on the moon?
no, sound cannot travel to the vacuum of space

What are programs introduced by Space Camp for students?
Space Camp is just not an ordinary camp, its a camp for students where they just dont hear about what astronauts d, they do what astronauts do. The programs under Space Camp include: shuttle missions, underwater astronaut training, space shot etc. For more information you can log in to www.spacecampindia.com.
Can astronauts hear each other?
As there is no air , it is difficult , but astronauts use radios.
