Viewed from inside the Vehicle Assembly Building, Space Shuttle Discovery, atop the mobile launcher platform (MLP), begins its rollout to Launch Pad 39A before dawn. Beneath the Space Shuttle and MLP is the crawler-transporter that moves it all to the pad. Discovery is scheduled to launch Oct. 5 at 9:30 p.m. EDT on mission STS-92. Making the 100th Space Shuttle mission launched from Kennedy Space Center, Discovery will carry two pieces of hardware for the International Space Station, the Z1 truss, which is the cornerstone truss of the Station, and the third Pressurized Mating Adapter. Discovery also will be making its 28th flight into space, more than any of the other orbiters to date
