(06/21/2001) -- Viewed from below, Space Shuttle Discovery nearly hides the orange external tank behind it. The twin solid rocket boosters can be seen on either side. Discovery waits in the Vehicle Assembly Building for rollout to Launch Pad 39A. Inclement weather has been a prime factor delaying the rollout. Discovery is scheduled for launch no earlier than Aug. 5 on mission STS-105, carrying the Expedition Three crew that will replace Expedition Two on the International Space Station
