Space Shuttle Endeavour sits atop the mobile launcher platform and crawler transporter after rollout from the Vehicle Assembly Building.

In the cloud-dimmed light of early morning, Space Shuttle Endeavour sits in place at Launch Pad 39A , atop the mobile launcher platform and crawler transporter, after rollout from the Vehicle Assembly Building. At its left are the Rotating Service Structure and Fixed Service Structure with the orbiter access arm extended. The access arm swings out to the orbiter crew compartment hatch to allow personnel to enter the crew compartment. At its outer end is the white room, an environmental chamber, that mates with the orbiter. While at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-88 launch targeted for Dec. 3, 1998. Mission STS-88 is the first U.S. flight for the assembly of the International Space Station and will carry the Unity connecting module. While on orbit, the flight crew will deploy Unity from the payload bay and connect it to the Russian-built Zarya control module which will be in orbit at that time. Unity will be the main connecting point for later U.S. station modules and components. More than 40 launches are planned over five years involving the resources and expertise of 16 cooperating nations. Comprising the STS-88 crew are Commander Robert D. Cabana, Pilot Frederick W. "Rick" Sturckow, Mission Specialists Nancy J. Currie, Jerry L. Ross, James H. Newman and Russian cosmonaut Sergei Konstantinovich Krikalev. Ross and Newman will make three spacewalks to connect power, data and utility lines and install exterior equipment
