I even hear it during talk back, but mostly I hear an occasional single beep at even intervals during NASA space communications and lunar landing footage. What is it and why does it happen? I ask because I can't think of a reason why we hear the beeps together with the astronaut's voices and static.

It is what is called a "roger beep". It is widely used in professional and amateur simplex voice radio communications(CB, police, military). If you ever used a walkie talkie and it had a roger beep functionality this beep comes out of your transmitter every time you release the "push to talk" button to notify the other users of the frequency channel that they can start speaking. It saves you from saying "over" or "roger" all the time.

Well, I'd never really concidered it..

But if I had to venture a guess, I'd say to assure that nothing has happened. I don't think they'd hear a "Boom" if it exploded a hundred miles up.

But then, most of the equipment is monitored from the ground, if something happened they'd probably be aware of it, if nothing else, by the total lack of signal.

Dunno.
