Intellectually, I'd known I was venturing out into space yet still the sight of it shocked me, profoundly. In a spacesuit, you're not aware of taste, smell, touch. The only sounds you hear are your own breathing and, through the headset, disembodied voices. You're in a self-contained bubble, cut off, then you look up from your task and the universe rudely slaps you in the face. It's overpowering, visually, and no other senses warn you that you're about to be attacked by raw beauty.
