NASA managers just gave a "go" for engineers to begin loading Discovery's 15-story external tank for a launch attempt at 3:04 p.m. today.More than 500,000 gallons of liquid hydrogen and liquid oxygen will be pumped into the bullet-shaped tank.

The tanking operation is scheduled to begin at 5:39 a.m. It is expected to take three hours to complete.
