Quote:I do NOT understand why they won't just PAINT THE DAMN TANK!Because paint has mass, and it takes reaction mass to push that mass into the air.
I believe the choice is to lift paint on the external tank up to the separation altitude or lift another day's rations for the crew into orbit; given that, I'm quite happy seeing unpainted external tanks.
