In space, there is no air to carry sound waves. Sound waves are vibrations that travel through a medium, such as air, water, or solid objects. Without a medium to carry the vibrations, sound cannot be transmitted. This is why astronauts in space cannot hear one another or any other sounds. They must use radios or other communication devices to communicate with one another.
