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.
Can you hear any sounds in space?
In space, sound does not travel because it is a vacuum, meaning there are no molecules to carry sound waves. Astronauts can communicate using radio transmissions inside their spacecraft, but they cannot hear sound like we do on Earth as there is no medium for sound to travel through in outer space.
Why do astronauts use radio waves instead of sound waves to communicate in space?
sound needs something to travel through and space has no air for it to travel
What do astronauts do in outer space?
They study how long to get to planets and if there is life in outer space.
How do astronauts survive in outer space?
with space suits
Why did astronauts who did experminets on the moon communicate with each other using walkie talkies even when they were right next to one another?
Sound needs to travel in medium like air, but there is no air in outer space, so sound is unable to travel. So basically sound needs air to travel, if there is no air sound cannot travel, when sound is unable to travel you cannot communicate (talk, speak, etc)
How do astronauts navigate in outer space?
radar
What are space suits?
These are the suits that the astronauts wear when they travel to outer space.
Why does an astronauts float when he is in outer space?
Because there is zero gravity in space
Do astronauts leave the ISS while in outer space?
no
What are the problems met by astronauts in outer space?
There are several problems met by astronauts in outer space. These problems include oxygen, radiation, gravity, weight, temperature, and food.
Why can't we communicate in outer space?
We can if we use radio. Without it, sound waves can't travel through space because there is no air for it to travel through.
