The STS-92 crew begin their journey to Launch Pad 39A with a snack. Seated at the table (left to right) are Mission Specialists William S. McArthur Jr., Leroy Chiao and Koichi Wakata of Japan; Commander Brian Duffy; Pilot Pamela Ann Melroy; and Mission Specialists Peter J.K. “Jeff” Wisoff and Michael E. Lopez-Alegria. 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. 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. Launch is scheduled for 7:17 p.m. EDT. Landing is expected Oct. 22 at 2:10 p.m. EDT
