In the bright morning sun, Space Shuttle Discovery towers above the landscape, and cars below, as it sits on Launch Pad 39A. At left can be seen the environmental chamber known as the “white room” that provides access inside the orbiter when it is in place. The white room is at the end of the Orbiter Access Arm, moved away from the Space Shuttle in this photograph. 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
