In the Space Station Processing Facility, members of the STS-92 crew get a close look at the Integrated Truss Structure Z1, part of the payload on their mission. STS-92 is the fifth U.S. flight in the construction of the International Space Station. The crew comprises Mission Commander Brian Duffy, Pilot Pamela A. Melroy, and Mission Specialists Koichi Wakata, Leroy Chiao, Peter J.K. Wisoff, Michael E. Lopez-Alegria, and William S. McArthur Jr. Wakata is with the National Space Development Agency of Japan. The Z1 is an early exterior framework to allow the first U.S. solar arrays on a future flight to be temporarily installed on Unity for early power. Another part of the payload is a pressurized mating adapter, PMA-3, to provide a Shuttle docking port for solar array installation on the sixth ISS flight and Lab installation on the seventh ISS flight. Launch of STS-92 is scheduled for Sept. 21, 2000
