The STS-92 crew strides eagerly to the waiting Astrovan that will take them to Launch Pad 39A for liftoff at 8:05 p.m. EDT to the International Space Station (ISS). They are (from front to back) Pilot Pamela Ann Melroy and Commander Brian Duffy; and Mission Specialists Leroy Chiao and William S. McArthur Jr.; Peter J.K. Wisoff; Michael E. Lopez-Alegria and Koichi Wakata of Japan. 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 second for Wakata. Landing is expected Oct. 21 at 3:55 p.m. EDT
