Why can astronauts not talk to each other without communication equipment on the moon?

There is no air on the moon. Sound waves only propagate through a medium, such as air, water, etc. Sound waves cannot propagate through a vacuum, therefore the astronauts had to use radios to speak to each other.

What does an astronauts do on a planet?
The only place astronauts have been other than Earth, is on the moon. When they were there, they did some exploring to see what it was like. They took samples of the soil and rocks to bring back to Earth. They tried to learn as much as they could while they were there. If astronauts get to visit other planets, they would do the same kinds of things.

Can you touch planets?
Sorry to bring down your dream, but you cannot touch other planets unless you have some sort of equipment, like astronauts have. But you are touching Earth. :D
Can astronauts hear each other?
As there is no air , it is difficult , but astronauts use radios.
Who were the other astronauts on the mission with Neil Armstrong?
The other astronauts were Michael Collins and Edwin E. Aldrin Jr
What items are not allowed on the space shuttle?
Astronauts aboard the space shuttle, like other space craft including the ISS, have to be most careful about loose items in micro-gravity. Food in particular is carefully planned to prevent crumbs and other small bits from getting loose and ending up in sensitive equipment or in an astronauts eye.
Who flew on the space shuttle?
Astronauts aboard the space shuttle were primarily NASA astronauts, astronauts from Canada, Europe and other countries.
Astronauts on a space walk cannot hear each other. Why?
They can not hear each other through the natural environment due to there being no medium for the sound waves to travel through. However, they can hear each other through the use of radio communication.
