Sound is carried by vibrations of molecules. When you talk here on Earth, air molecules transmit the vibrations and allow others to hear you. In open space there are very few molecules at all so there is nothing to carry the vibrations.
Radios use radio waves to transmit information from one to another. These waves move through space by themselves so they can be transmitted from one astronaut to another. Then the radio turns the wave back into sound in the air filled compartment the astronauts breath in.

Why do astronauts in space have to use radios to talk to each other?
Astronauts in space use radios to communicate because sound cannot travel in the vacuum of space, where there is no air to carry sound waves. Radios convert voice into electromagnetic signals, which can travel through the vacuum and be received by other radios. This communication is essential for coordinating tasks, sharing information, and ensuring safety during missions. Additionally, radio communication allows astronauts to stay in contact with mission control on Earth.
Why did astronauts use radios to talk on the moon?
There are many reasons, but significant ones are related to available atmosphere. The astronauts must stay in their space suits to get breathable air. Denser air is better for the transmition of sound. So it is hard to get sound to go through the space suit and then hard to get it to go through the low density atmosphere of the moon. Radios are easier and can go much farther.
Why did the astronauts have to use radios on the moon?
Astronauts on the moon used radios to communicate with mission control and other astronauts. The distance to Earth was too great for them to communicate in real time without radios. Additionally, the space suits and helmets they wore made it difficult to communicate verbally with each other.
How do astronauts communicate in space?
Astronauts mainly communicate in space using radio waves. They use radios to talk to mission control on Earth and to communicate with each other inside the spacecraft. They can also use video conferencing and email for communication purposes.
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.
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 do astronauts who land on moon talk through wireless sets using radio waves?
Sound needs air to travel through, and as there's no air on the moon. Astronauts have to use radios to talk to each other when in an envrionment without air. Radio waves travel through space and have no trouble traveling where there's no air.

How do astronauts talk to their families?
Just like anyone else does. On the phone! If they are in space they don't talk to their family probably.
What do astronauts do all day in space?
Astronauts in space spend their days conducting experiments, maintaining the spacecraft, exercising to combat muscle and bone loss, communicating with mission control, and documenting their experiences through photography and videography. They also have scheduled periods for relaxation and personal time.
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.
What do astronauts take with them to the moon?
If you are travelling to space, you would have to take:FoodWaterOxygenA radio (to talk to your families on Earth)A camera (to take pictures of the planets)We're sorry if this did not answer your question, but it did answer a little bit of it.
