If the pressure inside of the lunar module was 1/5 that of Earth, would that mean the astronauts breathing would be affected? Go into a room and begin sucking out the air, I bet soon you'd become lightheaded. I'm no doctor but that's my thinking on that theory. Yea, it's feasable that the craft could withstand 1/5 atmosphere, but could the crew?
