I'm allowing myself to use this thread to ask a related question. I was just wondering, in this video: http://youtube.com/watch?v=tKZzFTLrNvc
, what's that white gas/liquid coming from those small nozzles by the main engines? (first seen after about 6 seconds).
I don't know, but it might be the exhaust for some kind of cooling system in the engine.

The main purpose of the water is not cooling, but absorbing the sound wave energy from the rocket engines. Without it the whole platform would be shaken to pieces, or so I was told when I visited Florida. At 3:10 in the video he says "Sound Suppression Water System is armed.".
