Eager to get to the launch pad and liftoff of Space Shuttle Discovery on mission STS-92, the crew hurries to the waiting Astrovan for the trip. From left are Mission Specialists Michael E. Lopez-Alegria, Koichi Wakata of Japan, William S. McArthur Jr., Leroy Chiao and Peter J.K. “Jeff” Wisoff; Pilot Pamela Ann Melroy; and Commander Brian Duffy. This launch is the fourth for Duffy and Wisoff, the third for Chiao and McArthur, second for Wakata and Lopez-Alegria, and first for Melroy. During the 11-day mission to the International Space Station, four extravehicular activities (EVAs), or spacewalks, are planned for construction. The payload includes the Integrated Truss Structure Z-1 and the third Pressurized Mating Adapter. The Z-1 truss is the first of 10 that will become the backbone of the Space Station, eventually stretching the length of a football field. PMA-3 will provide a Shuttle docking port for solar array installation on the sixth Station flight and Lab installation on the seventh Station flight. Launch is scheduled for 7:17 p.m. EDT. Discovery’s landing is expected Oct. 22 at 2:10 p.m. EDT
