Can astronauts talk to each other in space?

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. That’s why the astronauts use radios to communicate—even if they’re floating in space right next to each other!

Can we talk without gravity?

The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. Their inability to talk directly is not caused by their helmets getting in the way, but is rather caused by the vacuum of space not carrying sound at all.

How does astronauts talk to each other?

How do astronauts communicate with each other? The astronauts have devices in their helmets which transfer the sound waves from their voices into radio waves and transmit it to the ground (or other astronauts in space). This is exactly the same as how your radio at home works.

Why can’t astronauts talk to each other in space?

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.

Can zero gravity be created on Earth?

Microgravity, which is the condition of relative near weightlessness, can only be achieved on Earth by putting an object in a state of free fall. Allowing the experiment hardware to free fall a distance of 432 feet (132 m) creates the microgravity environment at the Zero-G facility.

Why is it quiet in outer space?

In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears.
