At NASA's Kennedy Space Center in Florida, Discovery -- sitting atop an orbiter transporter -- nears the Vehicle Assembly Building. The orbiter's "rollover" from its processing facility is a milestone in prelaunch preparation. Once inside, Discovery will be raised to vertical and lifted up and over into high bay 3 for stacking with its redesigned external tank and twin solid rocket boosters.
In about a week, Discovery is expected to roll out to Launch Pad 39B, with the launch of mission STS-121 scheduled to take place during a window extending July 1 to 19.
