    There’s a theory that astronauts may be able to communicate in space without their radios by touching helmets together. Don’t know if it’s ever been tried.

    And speaking of touching helmets, I can imagine another version of this comic where Bob is making a sexy scream, instead.

      Searched a bit and surprisingly couldn’t find any agency communication about this. I found that they use some gestures though.

        I saw somebody do the math and say that this method would dampen the voice so much that it might as well be said not to work. But I don’t know much about this topic, and I can’t say whether the math is correct, either.

        I mostly brought it up because it was interesting and let me make a joke about “touching helmets”.

          It is essentially the same concept as trying to listen in on a conversation in another room by putting your ear up to the wall.

          It technically works, but making out what is being said is not easy unless the other party is being exceptionally loud.

            In that case, it seems like the saying would be “In space, people can only hear you scream.”

          Maybe some special physical interface could be built in the helmet, but if space agencies never came up with a solution for this, it probably means it is not needed.
