The STS-92 crew pose for a group photo after a snack prior to suiting up for launch. Seated left to right are Mission Specialists Peter J.K. “Jeff” Wisoff and Michael E. Lopez-Alegria; Pilot Pamela Ann Melory; Commander Brian Duffy; and Mission Specialists Koichi Wakata of Japan, William S. McArthur Jr. and Leroy Chiao. The mission is the fifth flight for the construction of the ISS. The payload includes the Integrated Truss Structure Z-1 and the third Pressurized Mating Adapter. During the 11-day mission, four extravehicular activities (EVAs), or spacewalks, are planned. The Z-1 truss is the first of 10 that will become the backbone of the International 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 ISS flight and Lab installation on the seventh ISS 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 8:05 p.m. EDT. Landing is expected Oct. 21 at 3:55 p.m. EDT
