What song did they play when Neil Armstrong went out on the moon?

That event didn't need any musical background to set the mood, and it wasn't presided over by a disc jockey. There were some people on the TV broadcast, but even they were not saying anything. The only sounds we heard were the voices of the two men on the moon and the voices from the control center in Houston with whom they were in constant contact.


How can you tell if your a daughter of Zeus?

Well if you take Greek mythology you can memorize a lot and you will probably hear voices in your head and you would love lightning and probably feel connected to him. You may also have an addiction to bright things and bossing people around. You will most likely be drawn to wheather. The wheather may affect your mood, e.g. stormy=angry sunny=happy, cloudy=in between.


Why did the astronauts who walked on the moon have to use radios to talk to each other?

sound waves are mechanical waves that needs a medium such as air to travel through while radio waves are electromagnetic waves which doesn't need such medium to propagates. ofcourse there is air on the moon so may be the right answer is because astrounates cannot breath on the moon that's why they are using radio waves.


Why are their no sounds in outer space?

Sound is carried by vibrations of some material; normally vibrations in the atmosphere. Sounds can also be carried by vibrations in the ground or in the water. If you've ever seen old western movies, you might have noticed the scout putting his ear to the ground to "hear" far-off hoofsteps. Or if you've ever been at the ocean, you might have noticed that when you put your head under water, you can hear the sounds of fish, or ships, very clearly. There is no atmosphere in space, so there is no medium that can carry sound. However, if you were outside of a spaceship and you touched your space helmet to the hull of the ship, you'd be able to hear sounds within the ship; perhaps even the voices of people talking inside the ship. ===================== Answer 2 Sound waves need material medium to travel. In space there is nothing. Hence there is no sound. But it is wrong to say there is nothing as there is an ocean of particles in outer space. So the sounds that are produced is too low for any person to hear. Scientists have been able to capture these sounds and amplified it so that anyone can hear it.
