astronauts in space?

Question

How could two astronauts repairing the outside of a space shuttle talk to and hear each other without using radios?

Answer 1

see acc. to physics theory sound cannot travel in vaccum so space astranauts need to use radio waves in the form of wireless phones to communicate with each other,acc to u they r able to listen to each other without radio waves then there must be some other and developed device through which they can communicate.but without any such i disagree with u, they cannot communicate.u must be having som wrong information. check it out dear

Answer 2

To correct a previous answerer, yes radio do travel through a vacuum, ALL forms of electromagnetic radiation travel through a vacuum. Did the Apollo missions trail a piece of wire all the way to the moon?!?!? Has Voyager been trailing a piece of wire through the solar system?
The simplest ways to communicate in space would be through hand signals, another way that will work is by touching helmet visors. Since the sound of one voice vibrates one visor and those vibrations can be passed to the other visor.

Answer 3

They'd have to be in physical contact. With speach and sound being the result of waves or vibrations traveling through air, the only way to communicate without radios would be to allow the air inside the spacesuit to conduct the sound waves by contact. (most effectively by touching faceplates.

Answer 4

that's a international area Station - the final commander, who did the kind of excellent pastime of providing technological know-how to college little ones on an identical time as up there, became Canadian. the human beings sent up are specifically experienced to accomplish scientific experiments prepare on earth in countless international locations - they in many cases practice for months or years to get each and every thing to paintings surprising. The budget for the experiments consists of the value of having the guy up there. the human beings on board have finished working schedules and are saved busy. WE paid for most of the products of the ISS - this isn't any longer a Russian or Soviet station - and the crews of 6 each and every person isn't "completely manned by means of Russians" We all started dumping funds into this methodology on the commencing up by means of fact we (or they) destroyed the communist run Soviet Union (ask Ronald Reagan followers approximately their version) and we might have loved to no longer lose what we had already cooperated on.
