Shuttle managers have set tomorrow at 12:39 EDT as the new launch date for STS 115. This time, things are looking a little better: there’s only a small chance of thunderstorms and no tropical storms or hurricanes in the Gulf of Mexico.
Still, the Air Force weather folks, who do forecasting for launch days, say that lift off isn’t a sure thing. Strict launch weather conditions mean that puffy cumulous clouds may be enough to force a scrub, and there is a chance of scattered showers at the Shuttle Landing Facility a few kilometres from the launch site. The bottom line is that the shuttle has only a 70% chance of getting off the ground tomorrow.
I’m headed back this afternoon, and I’ll write more when I arrive.
