NASA began fueling its most traveled shuttle shortly after sunrise Thursday. The weather outlook has improved to 90% "go" for the 4:50 p.m. (2150 GMT) liftoff.
This time, NASA is confident no hydrogen gas will leak and no cracks will develop in the fuel tank. Both problems cropped up during the initial countdown in November. The repairs took almost four months.

I will be watching from my patio, and praying for a safe flight.
