All Helmets Are To Remain On Until We Return to the Atmosphere

This morning, as Daniel knelt on the floor in a corner of his bedroom making a space ship out of legos, he discussed out loud why it is that astronauts must wear helmets at all times while they're in space:

"In outer space, you really would have to have helmets, because then, like all the gravity all around you has like something that can make you not breathe any more, so you wouldn't want to take off your mask there. ...So you would really need to keep your helmets on.
