Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut's whistling can't travel over to the other astronaut's ears. That's why the astronauts use radios to communicate—even if they're floating in space right next to each other!

Answer 2

Answer:

Sound cannot travel in space as there is no air in space. Astronauts use microphones.

Explanation:

Sound needs a medium to travel i.e usually air. Microphones are part of the astronauts‘ head set.
