No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
This is because there is no air on the moon and it is a vaccum( no medium). Thus there is no medium for sound waves to travel.So two persons cannot hear their voice on moon. Q. There is no atmosphere on the moon.
Now, when the two astronauts are floating close to each other in space, without the use of any special device, they cannot talk to each other because there is vacuum between them. As there is vacuum, it means there are no molecules or particulate matter between them for the sound to travel.
Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...
No, there isn't sound in space.
This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.
On the surface of the moon, there is no air. As there is the absence of a medium, sound doesn't travel. Hence, we cannot hear anyone talking on the surface of the moon.
No, they cannot hear each other on the moon's surface because sound requires a medium to travel and since it is vacuum on the moon's surface, transmission of sound is not possible. Q. There is no atmosphere on the moon.
The moon does not have atmosphere. Since there is no medium which is necessary for generation and propagation of sound, between the astronauts, direct sound propagation between them is not possible.
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!
Sound cannot travel through the vacuum of space, but visible light and other forms of electromagnetic radiation can. One of these forms is commonly called radio.
While wearing the current space suits, astronauts wear a Communications Carrier Assembly (CCA), or "Snoopy Cap" — a fabric hat fitted with microphones in the ear area for listening and boom microphones in front of the mouth for speaking. These caps are worn under the helmet and visor that surround an astronaut's head.
Due to its less gravity, the atmosphere is not present on its surface. The air molecules are not present on the moon. Sound requires a medium to travel. Thus when we walk on the surface of the moon then the sound of our footsteps can not be heard.
Explanation: No, they can not hear each other on the moon. It is because there is no atmosphere (or medium) on the moon, and the sound needs a medium to travel.
Space has no air. Since sound waves require a material medium to propagate, therefore, astronauts cannot talk to each other in space.
The United States is the only country to have successfully conducted crewed missions to the Moon, with the last departing the lunar surface in December 1972.
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don't interact with one another). Thus there is no sound on the Moon.
Radio waves propagate in vacuum at the speed of light c, exactly 299,792,458 m/s. Propagation time to the Moon and back ranges from 2.4 to 2.7 seconds, with an average of 2.56 seconds (the average distance from Earth to the Moon is 384,400 km).
There are only a few places in the world where you can touch a piece of the Moon brought back during the Apollo missions, and they are all from this Apollo 17 sample. Recently, the Moon rock was briefly off display as we moved it to another place in the gallery. It is back now for our visitors to enjoy.
Although you might think it would be cool, humans could not live on the moon! (Maybe one day in the future…) The moon has almost no atmosphere, so there's no air for us to breathe. There is no water on the moon either, and we need to drink water to survive.
A device that would not work on the Moon is Siphon.
Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.
The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. These pressure waves steepen into shock waves and this is possibly why the corona gets so hot.
In theory, the footprints on the moon can last as long as the moon itself. However the moon is always being bombarded by micro-meteorites and charged particles from the Sun, putting the life-span of these footprints at around 10 - 100 million years.
So astronauts cannot hear each other in space as sound cannot travel in space. Q.
Once aboard the ISS, the crew communicates in a mixture of English and Russian, so astronauts must be fluent in one of those languages and have a high degree of competency in the other.
