Because sound needs particles to travel through ; when a sound from inside one helmet is made, the particles vibrate the surrounding particles therefore vibrating the other astronauts helmet particles ( as they are touching) allowing him to hear the sound.
Right now, Astronauts and Cosmonauts live inside the space station that orbits Earth.
because of unavailability of gravity.
Everyone needs to be protected against radiation, because radiation in strong doses can Kill or injure. A small amount that a person receives in an x-ray will do no harm; but, too strong a dose of radiation is very dangerous. Radiation is greater in outer space than it is on the earth, because, we are protected from radiation on earth by the atmosphere. Astronauts in outer space have no such protection.

Yes, albeit a very very expensive one.
Air vibrates helmet. Helmet vibrates helmet (two). Helmet vibrates air (inside helmet two).
