So the countdown is continuing, and the weather looks fantastic. Here's the expected timeline from this point, assuming that the launch happens at the very opening of the launch window. I asked John Spencer last night what the two-hour launch window meant for the probable launch time, and he said, "The plan is indeed to launch as soon as the launch window opens -- let's hope that actually happens!" Cross your fingers...
