In the Orbiter Processing Facility, STS-115 Mission Specialist Joseph Tanner gets familiar with a camera that is a mockup of one the crew will use to take photographs on-orbit. With him are Mission Specialists Steven MacLean, who represents the Canadian Space Agency, and Heidemarie Stefanyshyn-Piper. The crew is at the center for Crew Equipment Interface Test activities, which involves equipment familiarization, a routine part of astronaut training and launch preparations. The mission will deliver the second port truss segment, the P3/P4 Truss, to attach to the first port truss segment, the P1 Truss, as well as deploy solar array set 2A and 4A. Launch on Space Shuttle Atlantis is scheduled for late August. Photo credit: NASA/Kim Shiflett
