July 4th and Discovery

We are less than ten minutes until Discovery's scheduled lift-off. They say the third time is the charm, well this is the third time. A bit of foam has fallen off the eternal tank but NASA is not worried - the amount of foam coming off the external tank increaded when NASA switched to a non-CFC insulation which makes me wonder why don't NASA go back to giving the foam a light coat of white paint to see if it helps hold the foam together. Yes I know the lack of paint saves weight, but there have been changes to the orbiters since they went orange with the third mission's tank that make the orbiters themselves lighter. Fox News is talking about how tight the window is to get to the International Space Station. Circuit breakers to keep the heaters going on the SRB seals has popped but NASA is still go. Truthfully considering the temperatures I have to wonder why the heaters were even going, this is not the weather Challenger lifted off in to explode 73 seconds later.

God speed Discovery, safe voyage.
